Water Management – Institutional Reforms, Conservation Efforts, etc.

Water Management – Institutional Reforms, Conservation Efforts, etc.

Our water challenge is stark. Here are four ways to reimagine the solutions

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

India’s water crisis has reached a critical threshold, with per capita availability nearing scarcity levels and over 80% districts exposed to hydro-meteorological disasters. A major shift is being proposed, from viewing water as a free resource to treating it as a strategic economic asset.

Why is India’s water crisis structurally alarming?

  1. Resource Imbalance: India supports 18% global population with 4% freshwater, indicating structural scarcity.
  2. Declining Availability: Per capita availability dropped from 1,816 (2001) to 1,486 cubic metres (2021); projected to approach 1,000 cubic metres by 2050.
  3. Climate Variability: Monsoon patterns exhibit unpredictability, with increased rainfall intensity but fewer rainy days, causing floods and droughts simultaneously.
  4. Disaster Vulnerability: Over 80% of the population lives in districts prone to hydro-meteorological disasters.
  5. Groundwater Stress: India is the largest extractor of groundwater globally, leading to depletion and unsustainable use.

How does mismanagement aggravate the water crisis?

  1. Agricultural Inefficiency: Agriculture consumes ~90% of freshwater, dominated by water-intensive crops like rice and sugarcane.
  2. Policy Distortions: Subsidies on water, power, and fertilizers incentivize inefficient usage.
  3. Urban Mismanagement: Urbanization increases runoff, reduces groundwater recharge, and intensifies flooding risks.
  4. Wastewater Neglect: Only 28% of wastewater is treated, leading to pollution and loss of reusable water.
  5. Infrastructure Deficit: Lack of integrated water systems limits storage, reuse, and efficient distribution. 

Why must water be redefined as an economic resource?

  1. Economic Transformation: Recognizing water as a strategic national asset ensures efficient allocation across sectors.
  2. Governance Shift: Moves from free-resource perception to regulated and priced commodity.
  3. Incentive Alignment: Pricing mechanisms discourage overuse and encourage conservation.
  4. Sectoral Efficiency: Enables prioritization of high-value economic uses over inefficient consumption. 

What broad strategic approach is required before detailing specific solutions?

  1. Paradigm Shift in Water Governance: Recognises water as a finite economic and ecological resource, not a free good, ensuring efficient allocation and accountability.
  2. Integrated Water Resource Management (IWRM): Ensures holistic coordination across sectors (agriculture, urban, industry) and scales (local to national) for sustainable use.
  3. Demand-side Management Focus: Prioritises efficiency and conservation over supply expansion, especially in agriculture and urban consumption.
  4. Ecosystem-based Approach: Strengthens natural water systems (forests, wetlands, soils) to enhance recharge, storage, and resilience.
  5. Decentralised and Participatory Governance: Empowers local institutions, communities, and stakeholders for context-specific water management.
  6. Technology and Data-driven Management: Facilitates real-time monitoring, digital water accounting, and evidence-based policymaking.
  7. Circular Economy Orientation: Promotes reuse, recycling, and recovery of wastewater, reducing pressure on freshwater sources.

How can green water and ecosystem-based approaches help?

  1. Green Water Concept: Soil moisture (rainfed water) constitutes ~60% of rainfall storage globally, critical for agriculture.
  2. Soil Degradation: Chemical-intensive farming reduces soil’s water retention capacity.
  3. Nature-based Solutions:
    1. Mulching, no-till farming: Enhances moisture retention
    2. Agroforestry: Improves soil structure and water holding
  4. Forest Conservation: Protects upstream ecosystems and ensures downstream water availability.
  5. National Green Water Mission: Enables integrated landscape-based water management. 

How can agriculture transition towards water efficiency?

  1. Crop Diversification: Shift from water-intensive crops to millets, pulses, oilseeds.
  2. Irrigation Reform: Adoption of micro-irrigation (drip, sprinkler) systems.
  3. Subsidy Rationalisation: Reduces distortion in cropping patterns.
  4. Water Productivity: Aligns cropping with agro-climatic suitability.
  5. Data Insight: Agriculture uses nearly 90% water, yet contributes disproportionately lower economic output. 

What role can circular water economy play?

  1. Wastewater Reuse: Only 28% treated currently, indicating large untapped potential.
  2. Economic Potential: Treated wastewater could unlock a ₹3.2 lakh crore market by 2047.
  3. Industrial Reuse: Reduces freshwater demand in industries.
  4. Biogas & Fertiliser Recovery: Converts waste into energy and nutrients.
  5. Private Participation: Encourages PPP models in wastewater treatment infrastructure.

How should urban water management be redesigned?

  1. Sponge Cities Model: Cities absorb, store, and reuse rainwater through green infrastructure.
  2. Blue-Green Infrastructure:
    1. Wetlands
    2. Urban forests
    3. Permeable surfaces
  3. Flood Mitigation: Reduces runoff and urban flooding risks.
  4. Case Example: Restoration of ecosystems like Yamuna Biodiversity Park enhances resilience.
  5. Urban Expansion Challenge: Built-up area has increased by one-third since 2005, reducing natural recharge.

What governance reforms are required in water sector?

  1. Decentralised Governance: Empowers local bodies for water management.
  2. Digital Infrastructure: Enables real-time water accounting and monitoring.
  3. Transparent Pricing: Ensures cost recovery and discourages wastage.
  4. Regulatory Framework: Strengthens enforcement against illegal extraction.
  5. Swachh Bharat Mission 3.0: Targets decentralized wastewater management. 

Conclusion

India’s water crisis reflects systemic inefficiencies rather than absolute scarcity. A shift towards economic valuation, ecosystem restoration, efficient agriculture, and circular water systems is essential. Integrated governance and behavioural change remain critical for long-term sustainability.

India’s status as world’s rice leader augurs a water crisis

Explained | Agriculture | Mains Paper 3: Agriculture and related issues

Introduction

Rice production has expanded sharply due to assured procurement, rising subsidies, and export demand. However, groundwater-dependent irrigation has become the dominant mode in northern India. Despite strong monsoons in recent years, extraction rates exceed natural recharge. Government classification of aquifers as “over-exploited” or “critical” signals a structural imbalance between agricultural policy and water resource sustainability.

Why in the News

India overtook China to become the world’s largest rice producer in 2023, exporting nearly double the quantity compared to the past decade and producing over 140 million tonnes of rice. While this achievement was politically and economically celebrated, it has intensified groundwater extraction in Punjab and Haryana. Borewell depths have increased from 30-40 feet to 80-200 feet, indicating rapid aquifer depletion. Rice cultivation in India consumes 3,000-4,000 litres of water per kg, 20-60% higher than the global average, turning agricultural success into a water sustainability concern of national scale.

How did India become the world’s largest rice producer?

  1. Production Expansion: Annual rice output exceeded 140 million tonnes, surpassing China in 2023.
  2. Export Growth: Rice exports nearly doubled in the past decade due to global demand and domestic surplus.
  3. Policy Support: Minimum Support Price (MSP) assurance ensured farmer preference for rice cultivation.

Why is rice cultivation intensifying groundwater stress?

  1. High Water Requirement: Producing one kilogram of rice requires 3,000-4,000 litres of water, exceeding global norms by 20-60%.
  2. Groundwater Dependence: Punjab and Haryana rice farmers primarily rely on borewell irrigation.
  3. Aquifer Depletion: Groundwater levels declined from 30-40 feet to 80-200 feet, indicating unsustainable extraction.

What role do subsidies play in water over-extraction?

  1. Electricity Subsidies: Free or low-cost power encourages excessive pumping of groundwater.
  2. Price Incentives: Rice prices increased by ~70% over the past decade, reinforcing crop preference.
  3. Input Distortion: Subsidies discourage transition to less water-intensive crops.

Why are Punjab and Haryana particularly vulnerable?

  1. Irrigation Pattern: Dominant reliance on groundwater over surface irrigation systems.
  2. Weak Monsoon Resilience: Despite strong rainfall, extraction continues beyond recharge capacity.
  3. Critical Classification: Aquifers in both states fall under “over-exploited” or “critical” categories.

How does groundwater stress threaten food security?

  1. Farmer Costs: Deeper borewells require higher capital and energy inputs.
  2. Production Risk: Aquifer depletion increases vulnerability to weak monsoons.
  3. Systemic Stress: India produces more rice than domestic requirements, amplifying water stress without proportional food security gains.

What corrective signals are emerging?

  1. Crop Diversification Incentives: Haryana introduced ₹17,500 per hectare subsidy for switching to less water-intensive crops.
  2. Policy Limitation: Incentives are seasonal and lack long-term assurance.
  3. Institutional Recognition: Government data acknowledges unsustainable groundwater extraction trends.

Way Forward

  1. Crop Diversification
    1. Shift Incentivisation: Expands cultivation of less water-intensive crops such as pulses and oilseeds through multi-year income assurance.
    2. Procurement Reform: Aligns MSP and assured procurement with water-efficient cropping patterns.
  2. Rationalisation of Subsidies
    1. Power Pricing: Reduces indiscriminate groundwater pumping by restructuring free electricity for agriculture.
    2. Input Targeting: Replaces universal subsidies with direct income support decoupled from water use.
  3. Water-Efficient Irrigation
    1. Micro-Irrigation Expansion: Enhances adoption of drip and sprinkler systems to improve water productivity.
    2. Alternate Wetting and Drying (AWD): Reduces water use in paddy cultivation without yield loss.
  4. Groundwater Governance
    1. Aquifer Management: Strengthens block-level monitoring and annual recharge-extraction audits.
    2. Regulatory Enforcement: Restricts borewell depth expansion in over-exploited zones.
  5. Export Rationalisation
    1. Water Footprint Accounting: Integrates virtual water costs into export policy decisions.
    2. Surplus Management: Aligns export volumes with regional water availability.

Conclusion

India’s rise as the world’s largest rice producer reflects policy certainty, farmer responsiveness, and export competitiveness. However, the same policy framework has accelerated groundwater depletion in key agrarian states. Without reorienting incentives toward water-efficient agriculture, food security gains risk becoming ecologically unsustainable. Long-term agricultural resilience requires aligning production, procurement, and irrigation policy with groundwater realities rather than output maximisation alone.

PYQ Relevance

[UPSC 2020] What are the major factors responsible for making the rice-wheat system a success? In spite of this success, how has this system become a bane in India?

Linkage: This question directly links to MSP-led rice expansion, groundwater-intensive irrigation, and subsidy-driven cropping patterns, as highlighted in India’s rise as the world’s largest rice producer.

[20th November 2025] The Hindu OpED: Hidden cost of polluted groundwater

op-ed snap | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

PYQ Relevance

[UPSC 2024] The world is facing an acute shortage of clean and safe freshwater. What are the alternative technologies which can solve this crisis? Briefly discuss any three such technologies citing their key merits and demerits.

Linkage: This PYQ is important for UPSC as freshwater scarcity and contamination are core GS-III themes. The article links directly by highlighting toxic groundwater, failing treatment systems, and the urgent need for affordable purification technologies.

Mentor’s Comment

Groundwater contamination in India is no longer a silent environmental issue, it has become an economic, social, and public-health emergency. This topic is highly relevant PYQ for UPSC, as water scarcity and groundwater contamination are recurring GS-III themes. The article directly aligns by showing how polluted aquifers and weak treatment systems make alternative purification technologies essential for India’s water security.

Introduction

Groundwater, the backbone of India’s drinking water and irrigation systems, is now increasingly polluted with heavy metals, industrial residues, and excess fertilizers. Reports from multiple states reveal a rise in fluoride, arsenic, uranium, and nitrate contamination, creating a public-health disaster and long-term economic losses. The issue has moved from isolated pockets to a nationwide development challenge demanding regulatory urgency, technological solutions, and sustainable water governance.

Why in the News

Recent rounds of India’s Groundwater Quality Report (2022) and field evidence from Punjab, Gujarat, Telangana, and Haryana indicate a sharp rise in toxic contamination, including fluoride-linked deformities, arsenic poisoning, and uranium beyond safe limits. The scale is unprecedented: nearly 600 million Indians rely on groundwater, and contamination is now accelerating due to over-extraction, fertilizer misuse, and industrial discharge. The crisis is no longer environmental, it is weakening agricultural incomes, burdening households with high medical costs, and threatening India’s export competitiveness.

What Is Causing Groundwater to Become Toxic?

  1. Heavy Reliance on Groundwater
    • Over-extraction: Agriculture absorbs over 60% of India’s groundwater, exceeding sustainable limits in several districts.
    • Irrigation intensity: Canal systems have stagnated, forcing farmers to depend on tube wells.
    • Result: Declining water tables concentrate pollutants and accelerate toxicity.
  2. Chemical Contamination from Agriculture
    • Excess fertilizer and pesticide use: Leads to nitrate accumulation and leaching into aquifers.
    • Heavy metals: Arsenic, fluoride, uranium exceed permissible limits in many districts.
    • Impact: Childhood skeletal deformities, fluorosis, long-term organ damage.
  3. Industrial and Sewage Discharge
    • Untreated effluents: Lack of sewage treatment expands contamination beyond village boundaries.
    • Industrial residues: Agro-processing and manufacturing hubs increase heavy metal presence.
    • Outcome: Polluted aquifers affecting both rural and peri-urban areas.

How Groundwater Pollution Impacts Health and Society

  1. Rising Health Burden
    • Skeletal deformities, fluorosis, kidney damage: Result of toxic metals in drinking water.
    • Children disproportionately affected: Early-life exposure lowers future productivity.
  2. Debt and Medical Expenditure
    • High out-of-pocket expense: Families spend heavily on hospital visits and bottled water.
    • Wealthier households cope better: Poorer families cannot afford alternative water sources.
  3. Intergenerational Impacts
    • Impaired cognitive development: Arsenic and fluoride exposure affects education outcomes.
    • Lower economic mobility: Chronic illness depresses earning capacity.

How Groundwater Pollution Hurts Agriculture and the Economy

  1. Loss of Farm Productivity
    • Poor water quality reduces crop yields: Long-term exposure to contaminated irrigation water.
    • Heavy metals affect soil health: Reducing crop diversity and nutritional value.
  2. Threat to India’s Export Market
    • Buyers demand stringent quality checks: Contamination threatens rice, spices, fruits, vegetables.
    • The $50-60 billion agri-export sector risks losses due to toxicity and traceability issues.
  3. Vicious Cycle of Over-Extraction
    • Declining tables led to more drilling which leads to more contaminants: Increases farmer indebtedness.
    • High fertilizer use worsens soil chemistry: Further reduces sustainability.

Why Policy Failure Allowed This Crisis to Escalate

  1. Weak Enforcement of Pollution Norms
    1. Inadequate regulation of industrial discharge: Leads to untreated sewage entering aquifers.
    2. Poor monitoring: Rural areas lack regular water quality surveillance.
  2. Lack of Decentralised Treatment Systems
    1. Dependence on centralized schemes: Community-level solutions not prioritized.
    2. Delayed response: Slow implementation of purification units.
  3. Limited Agricultural Diversification
    1. Punjab’s water-intensive cropping pattern: Maintains heavy groundwater stress.
    2. Minimal shift to millets/pulses despite policy incentives.

Way Forward

  1. Nationwide Real-Time Groundwater Monitoring
    • Open access digital platform: Communities should know what they are drinking/using to irrigate.
    • Data-driven planning: Better targeting of polluted zones.
  2. Strengthen Industrial and Sewage Regulations
    • Strict enforcement of effluent norms: Prevent industrial leakages.
    • Expand sewage treatment infrastructure: Particularly in peri-urban zones.
  3. Agricultural Policy Reform
    • Shift away from water-intensive crops: Encourage pulses, maize, oilseeds.
    • Promote micro-irrigation: Reduce water table stress.
  4. Localised Water Purification
    • Community-level treatment plants: Immediate relief in severely contaminated areas.
    • Affordable household filtration for poor families.
  5. Long-Term Water Security Planning
    • Integrating health, agriculture, and environment: Holistic approach to water governance.
    • Prevent groundwater from becoming India’s next major economic crisis.

Conclusion

Groundwater contamination has transformed into a multidimensional crisis affecting public health, agriculture, exports, and intergenerational equity. Without strict regulation, real-time monitoring, and agricultural diversification, the economic and health losses will escalate. India must act decisively before the groundwater crisis becomes irreversible.

Heavy metals found in Cauvery fishes

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

Researchers from Bharathidasan University, Tiruchirappalli, reported alarming levels of heavy metal pollution in the Cauvery River and its fish species, warning against excessive consumption.

Key Findings of the Study:

  • Scope & Period: Conducted August 2023–February 2024, covering 18 sediment and 10 fish-sampling sites, analysing chromium (Cr), cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn).
  • Contamination Levels: Several rivers stretches showed cadmium and lead concentrations exceeding international safety limits in both sediments and fish tissues.
  • Pollution Hotspots: The Erode stretch emerged as the most polluted, influenced by textile dyeing, electroplating, tannery effluents, urban sewage, and agricultural runoff.
  • Bioaccumulation Pattern: Metal concentration followed the trend, liver > gills > muscle, reflecting tissue-specific accumulation in aquatic species.
  • Toxic Metal Dominance: Cadmium and lead were identified as the most toxic, persistent, and bioaccumulative, posing long-term ecological and health hazards.

Risks Associated:

  • Ecological Impact:
    • Heavy metals disrupt fish reproduction, growth, and survival, destabilising aquatic food webs.
    • Sediment toxicity alters microbial and plankton communities, reducing biodiversity and ecosystem resilience.
  • Human Health Risks:
    • Consumption of contaminated fish can cause carcinogenic and non-carcinogenic effects, particularly from cadmium and lead.
    • Cadmium affects kidneys and bones, while lead impairs nervous and cognitive functions, especially in children.
    • Chronic exposure linked to liver dysfunction, hypertension, and cancer.
  • Safe Consumption Limit:
    • Researchers recommend ≤2 fish servings/week (250 g each) to minimise health risk.
    • Continuous intake leads to cumulative toxicity and higher disease risk.

Back2Basics: Bioaccumulation and Biomagnification

What is Bioaccumulation?

  • Overview: It is the gradual buildup of toxic substances, such as heavy metals or pesticides, in the tissues of living organisms over time.
  • Mechanism: When uptake (from food, water, or sediment) exceeds the rate of excretion, contaminants accumulate within the organism’s body.
  • Example: Fish in the Cauvery absorb cadmium and lead from contaminated sediments and water faster than they can eliminate them, leading to higher internal concentrations than in their environment.

What is Biomagnification?

  • Overview: It refers to the progressive increase in the concentration of toxins as they move up the food chain.
  • Process: Smaller aquatic organisms ingest pollutants → fish eat these organisms → humans consume contaminated fish, resulting in magnified exposure.
  • Consequence: Top predators, including humans, end up with the highest toxin concentrations, making biomagnification a significant public health hazard in contaminated ecosystems.

 

[UPSC 2024] With reference to perfluoroalkyl and polyfluoroalkyl substances (PFAS) that are used in making many consumer products, consider the following statements:

1. PFAS are found to be widespread in drinking water, food, and food packaging materials.

How groundwater contamination is fuelling chronic illnesses

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

India’s groundwater is increasingly getting contaminated with toxic substances. Over 85% of rural drinking water and 65% of irrigation needs are met through groundwater, yet unregulated extraction, industrial waste, agricultural runoff, and poor sanitation have turned this life source into a silent killer.

Scale of the Crisis

The 2024 Annual Groundwater Quality Report by the Central Ground Water Board (CGWB) reported the following:

  1. Nitrates: Found in 20%+ samples (due to chemical fertilisers & septic tank leakage).
  2. Fluoride: Detected in 9%+ samples, leading to skeletal & dental fluorosis.
  3. Arsenic: Found in parts of Punjab, Bihar, Uttar Pradesh causing cancers & neurological damage.
  4. Uranium: Detected in Punjab, Andhra Pradesh, Rajasthan linked to kidney damage.
  5. Heavy metals: Iron, lead, cadmium, chromium, causing developmental & immune system issues.

Major Contaminants and Health Impacts

  • Fluoride Contamination: 
    1. Affects 230 districts across 20 states.
    2. Health impact: Skeletal fluorosis, stunted growth, joint pain.
    3. Rajasthan, MP, and UP report high prevalence.
    4. Example: Jhabua (MP) – 40% of tribal children affected
  • Arsenic Exposure:
    1. Concentrated in Gangetic belt.
    2. Health impact: Skin lesions, respiratory illness, cancers (skin, liver, kidney, bladder).
    3. Example: Ballia (UP) – Arsenic 200 g/L (20× WHO limit) linked to 10,000+ cancer cases.
  • Nitrate Pollution: 
    1. 56% districts exceed safe limits.
    2. Health impact: Blue Baby Syndrome in infants, gastrointestinal distress.
    3. Driven by fertilisers & poor waste management.
  • Uranium Contamination:
    1. Increasing due to over-extraction & phosphate fertilisers.
    2. Health impact: Nephrotoxicity, chronic organ damage.
    3. Example: Malwa (Punjab) – 66% samples risky for children.
  • Heavy Metal Pollution: 
    1. Sources: Industrial discharge, mining.
    2. Health impact: Neurological issues, anaemia, developmental delays.

Groundwater Death Zones: Case Studies

  1. Budhpur, Baghpat (UP) – 13 deaths in 2 weeks from kidney failure linked to industrial waste.
  2. Jalaun (UP) – Petroleum-like fluids from hand pumps due to underground fuel leaks.
  3. Paikarapur (Bhubaneswar) – Sewage leakage caused illness in hundreds.

Why the Crisis Persists: Root Causes and Systemic Failures:

  1. Institutional Fragmentation: Various agencies like the CGWB, the CPCB, the SPCBs, and the Ministry of Jal Shakti operate in silos, leading to a lack of a unified, coordinated approach.
  2. Weak Legal Enforcement: The Water (Prevention and Control of Pollution) Act, 1974, has inadequate provisions for groundwater. This, combined with lax enforcement and regulatory loopholes, emboldens polluters.
  3. Lack of Real-Time Data: Monitoring is infrequent and poorly disseminated. Without early warning systems, contamination is often discovered only after serious health consequences have emerged.
  4. Excessive Groundwater Extraction: Over-pumping lowers water tables and concentrates pollutants, making aquifers more vulnerable to both geogenic toxins and industrial contaminants.
  5. Deficient Waste Management: Inadequate industrial effluent treatment and poor sanitation infrastructure, especially in rural areas, allow pollutants to seep directly into aquifers

The Way Forward: A Multi-Dimensional Strategy

Addressing this crisis requires a bold, multi-dimensional strategy that integrates regulation, technology, health, and public participation.

  1. National Framework: Enact a comprehensive National Groundwater Pollution Control Framework with clear legal authority to regulate groundwater use and discharge.
  2. Modern Monitoring Infrastructure: Deploy real-time monitoring systems using sensors and public dashboards to create an early warning network.
  3. Targeted Remediation: Implement targeted interventions for specific contaminants, such as defluoridation plants in high-fluoride zones and arsenic removal technologies in affected regions.
  4. Waste Management Reforms: Enforce strict industrial effluent treatment norms and promote sustainable agricultural practices to reduce the use of chemical fertilizers.
  5. Citizen-Centric Governance: Empower local communities through Jal Gram Sabhas to manage local water resources, conduct community water testing, and raise public awareness.

Value Addition: Key Concepts:

  • Geogenic Contamination: Naturally occurring pollutants like arsenic and fluoride mobilized by human activity.
  • Anthropogenic Contamination: Human-induced pollution from industries, agriculture, and urban waste.
  • Skeletal Fluorosis: A debilitating condition causing bone deformities.
  • Methemoglobinemia (“Blue Baby Syndrome”): A potentially fatal condition in infants caused by nitrate-laced water.

Practice UPSC MAINS question:

“Groundwater pollution in India is no longer about scarcity—it is about safety and survival.” Discuss this statement with recent examples and suggest a multi-pronged approach to tackle this issue.

UNEP Frontiers 2025 Report on Legacy Pollutants

IOCRPrelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

The United Nations Environment Programme (UNEP), in its latest Frontiers 2025 report titled The Weight of Time, has warned that increased river and coastal flooding caused by climate change could unearth dangerous legacy pollutants from water bodies.

About Legacy Pollutants:

  • Definition: Legacy pollutants refer to toxic substances like heavy metals and persistent organic pollutants (POPs) that continue to remain in the environment even decades after their use has been banned or restricted.
  • Examples:
    • Heavy Metals: Lead, Cadmium, Mercury, Arsenic.
    • Persistent Organic Pollutants (POPs):
      • Pesticides: DDT (Dichlorodiphenyltrichloroethane), Aldrin, Endrin, Chlordane.
      • Industrial Chemicals: PCBs (Polychlorinated Biphenyls), Dioxins, Furans.
      • By-products: Produced from incineration, metal smelting, and waste burning.
  • Persistence: These substances are highly resistant to environmental degradation and accumulate in riverbeds, lakes, estuaries, and other sediment-rich ecosystems.
  • Health Hazards: Even at low exposure levels, legacy pollutants can cause: Neurotoxicity (nervous system damage), Immunotoxicity (immune disruption), Hepatotoxicity (liver damage), Reproductive toxicity (infertility, birth defects), Carcinogenicity (various cancers), Endocrine disruption etc.
  • Sources:
    • Past industrial practices, use of banned agricultural chemicals, and obsolete pesticide stockpiles.
    • Improperly managed chemical landfills, which still hold an estimated 4.8–7 million tonnes of POP waste globally.

UNEP Frontiers 2025 Report on Legacy Pollutants

Key Highlights of Frontiers 2025: The Weight of Time (UNEP):

  • Retreat of Toxins: Climate change-induced flooding can unearth and redistribute toxic legacy pollutants from contaminated sediments into the environment and food chain.
  • How? Floodwaters re-suspend heavy metals and POPs trapped in sediment.
  • Case Studies Cited:
    • Hurricane Harvey (Texas, 2017): Released mercury and carcinogenic chemicals from flood-induced sediment dispersal into Galveston Bay.

Groundwater crisis deepens in Karnataka’s hard rock terrain 

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

In a recent study, researchers from WELL Labs in Chennai studied Aralumallige and Doddathumakuru gram panchayats in the Upper Arkavathy watershed near Bengaluru, and found a sharp drop in groundwater levels caused by intensive farming practices.

What drives groundwater depletion in the Deccan Plateau?

  • Hard Rock Aquifers with Low Storage Capacity: The Deccan Plateau is underlain by basalt and granite (hard rock aquifers) that have limited porosity. These rely on fractures and weathered zones to store water, making them less efficient in holding groundwater. Eg: In Karnataka, 99% of the area depends on such aquifers, making sustainable storage difficult.
  • Deep Borewell Drilling Alters Natural Recharge: Borewells drilled into granite cause microfractures, allowing rainwater to bypass shallow aquifers and flow deep underground. This disrupts the natural recharge cycle and reduces groundwater retention.  
  • Water-Intensive Agriculture: Cultivation of vegetables, flowers, and exotic crops for urban markets like Bengaluru demands large volumes of groundwater. These crops are not suited to the dry, hard-rock geology of the region.  
  • Encroachment of Traditional Recharge Systems: Lakes and tanks, once used for groundwater recharge, are being encroached upon or neglected. Their discharge channels are blocked, eliminating natural recharge opportunities. Eg: The lake in Aralumallige (Karnataka), once a major recharge source, remained dry in 2022 despite heavy rainfall.

Why is reliance on borewells unsustainable in rural Karnataka?

  • Rapid Groundwater Depletion and Borewell Failures: Continuous extraction through deep borewells causes the water table to drop, making it harder to access groundwater over time. Eg: In the Upper Arkavathy watershed, the average borewell depth increased from 183m to 321m in just two decades. Over 70% of drinking water wells failed within 10 years of construction.
  • High Financial Burden on Farmers and Panchayats: Drilling deeper borewells costs ₹4–5 lakh, often unaffordable for small farmers, with no guarantee of success. Free electricity for pumping increases electricity consumption and debt for gram panchayats. Eg: Panchayats face mounting electricity bills, diverting funds away from development works to cover power costs.
  • Disruption of Natural Recharge and Local Hydrology: Borewells alter subsurface geology, causing rainwater to bypass shallow aquifers, reducing natural recharge. Eg: In Aralumallige and Doddathumakuru, borewell drilling weakened long-term water retention, contributing to chronic scarcity despite seasonal rains.

What is the socio-economic impact on local communities and governance?

  • Rising electricity debt: Free power for farmers fuels overuse, pushing gram panchayats into unsustainable debts as they divert development funds to pay power bills.
  • Borewell burden on small farmers: Drilling costs ₹4-5 lakh with no assurance of success, leading many farmers to lease land and migrate to cities.

What are the issues related to groundwater in Indian?

  • Overexploitation and Depletion: Unregulated extraction of groundwater for agriculture and urban use has led to rapid depletion of water tables. Eg: In parts of Punjab, Haryana, and Karnataka (like Aralumallige), water tables have fallen by over 100 meters in two decades due to borewell dependence.
  • Poor Groundwater Quality: Contamination by nitrates, fluoride, and arsenic poses serious health risks, especially in rural areas. Eg: In Bihar and West Bengal, arsenic contamination affects drinking water; in Karnataka, nitrate levels often exceed safe limits (50 mg/l).
  • Inadequate Data and Poor Management: Lack of real-time monitoring, insufficient local-level data, and fragmented water governance hinder sustainable planning. Eg: Despite groundwater overuse, local panchayats often lack predictive tools to estimate borewell failure or manage recharge zones effectively.

What are the steps taken by the Indian Government?

  • Jal Shakti Abhiyan (JSA): A nationwide water conservation campaign launched in 2019 to promote rainwater harvesting, recharge structures, and sustainable water use. Eg: In water-stressed blocks of states like Maharashtra and Rajasthan, the JSA promoted check dams and contour trenches to boost groundwater recharge.
  • Atal Bhujal Yojana (Atal Jal): A World Bank-assisted scheme launched in 2019 for sustainable groundwater management in 7 states. It focuses on community participation, water budgeting, and crop water use efficiency. Eg: In Gujarat and Madhya Pradesh, water user associations have helped monitor and reduce groundwater extraction.
  • Groundwater Regulation by Central Groundwater Authority (CGWA): The CGWA regulates groundwater usage in over-exploited areas by mandating No Objection Certificates (NOCs) for industries and commercial users.

Way forward: 

  • Promote Sustainable Farming Practices: Shift from water-intensive crops (like paddy, sugarcane) to less water-demanding crops suited to agro-climatic conditions.
  • Strengthen Local Water Governance: Empower Gram Panchayats to manage groundwater through community water budgeting, real-time monitoring, and local recharge efforts.

Mains PYQ:

[UPSC 2019] Enumerate the indirect taxes which have been subsumed in the goods and services tax (GST) in India. Also, comment on the revenue implications of the GST introduced in India since July 2017.

Linkage: The article talks about the GST replaced many older taxes like VAT and excise duty, helping create a single national market. Although GST collections have steadily grown—reaching ₹22.08 lakh crore in 2024–25—the revenue from tobacco (about ₹551 billion a year) is much less than the huge cost of tobacco-related health problems, which is ₹2,340 billion every year.

Two billion people don’t have safe drinking water

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

It’s shocking that 2 billion people around the world still don’t have access to safe drinking water, even though 95% of the global population uses what are called “improved water sources”. This reveals a hidden but serious public health problem.

IBAT Alliance

What defines ‘safe drinking water’?

Safe drinking water refers to water that is free from harmful contaminants such as bacteria, viruses, and chemicals. It must be located on the premises, readily available when needed, and safe to consume without causing health issues.

How does access vary across populations?

  • Majority Have Access, but Not Always at Home: While nearly 6 billion people have access to drinking water, around 2 billion still lack safe water at home.  Just 156 million people (around 1.4% of the global population) still collect water from unsafe sources like rivers or lakes.  
  • Disparities Exist Across Income and Geography: People in low-income or rural areas are more likely to lack access to safe, on-premises water. In most parts of Sub-Saharan Africa and South Asia, people still get their water from open sources such as rivers and lakes.

How does a lack of safe water impact public health in poor countries?

  • Spread of Waterborne Diseases: Unsafe water is a major source of diarrhoeal diseases like cholera, dysentery, polio, and hepatitis A. Over 800,000 deaths annually are attributed to waterborne illnesses, especially in low-income nations with inadequate sanitation.
  • Child Mortality and Malnutrition: Contaminated water contributes to malnutrition, as diarrhoeal diseases hinder nutrient absorption in children. In India, nearly 21% of children under five suffer from wasting (NFHS-5), with poor water and sanitation as key contributors. 
  • Healthcare Burden and Economic Loss: Frequent illness from unsafe water overwhelms fragile public health systems and reduces workforce productivity. In India, poor access to safe water and sanitation leads to an annual GDP loss of over 4% due to health and productivity issues (Ministry of Jal Shakti, 2021).

  • Progress in Access to Improved Water Sources: As of recent estimates, 95% of the global population uses an improved water source like piped water, borewells, and springs, even in many low-income countries.
  • Challenge of Household-Level Accessibility: Despite improvements, safe water is often not available at home, requiring people—mostly women—to travel long distances. Around 1.5 billion people still lack on-premise access, which limits reliability and increases the risk of contamination during transport.
  • Polluted water at the point of use: Water may be clean at the source, but it becomes contaminated during collection, storage, or transport.  

What are the alternative technologies which can solve this crisis?

  • Desalination Technology: Converts seawater into freshwater by removing salts and impurities using methods like reverse osmosis. Israel’s Sorek Desalination Plant provides 20% of the country’s water supply.
  • Solar Water Disinfection (SODIS): Uses UV rays from sunlight to kill bacteria and viruses in water stored in transparent bottles. It is widely used in rural Africa and India by households.
  • Atmospheric Water Generators (AWG): Extracts moisture from humid air and condenses it into clean drinking water. It was deployed in Rajasthan and UAE for areas with limited water but high humidity.

What are the steps taken by the Government?

  • Jal Jeevan Mission (JJM): Aims to provide functional household tap connections (FHTCs) with safe and adequate drinking water to all rural households by 2024. Eg: As of 2024, over 13 crore rural households have been provided with tap water connections under JJM.
  • Swachh Bharat Mission and Water Quality Monitoring: Focuses on reducing open defecation and water contamination by improving sanitation infrastructure and promoting hygiene.  
  • Atal Mission for Rejuvenation and Urban Transformation (AMRUT): Ensures universal water supply coverage in urban areas, with a focus on poor and underserved households. Under AMRUT, cities like Surat and Nagpur have significantly improved their 24×7 piped water supply networks.

Way forward

  • Strengthen Last-Mile Delivery through Infrastructure Expansion: Focus on household-level water connections, especially in rural and remote regions, by upgrading existing water supply networks and ensuring regular quality checks.
  • Promote Community-Based Water Management and Awareness: Encourage local governance (Panchayats, SHGs) and water user groups to manage water resources and promote safe water handling practices.

Mains PYQ:

[UPSC 2024] The world is facing an acute shortage of clean and safe freshwater. What are the alternative technologies which can solve this crisis? Briefly discuss any three such technologies, citing their key merits and demerits.

Linkage: The artice talks about the emphasizes that for water to be considered “safe drinking water,” it must be “free from contamination, located at home, and available whenever needed. This question directly addresses the global issue of an “acute shortage of clean and safe freshwater”. This directly aligns with the core problem presented in the article , which states that “two billion people” still do not have safe drinking water in their homes.

Water Management – Institutional Reforms, Conservation Efforts, etc.

[7th June 2025] The Hindu Op-ed: Water management in India needs a new course

op-ed snap | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

PYQ Relevance:

[UPSC 2013] Constitutional mechanisms to resolve the inter-state water disputes have failed to address and solve the problems. Is the failure due to structural or process inadequacy or both? Discuss.

Linkage: India’s water management problems are explicitly stated to be a result of a “fragmented and sectoral approach”. This contrasts sharply with the need for a holistic “new course.” The existing situation is problematic because “rivers and other waterbodies are often interstate and multiple political jurisdictions are involved in administering the same waterbody”.

 

Mentor’s Comment:  In 2025, global water governance takes a historic turn as the United Nations declares it the International Year of Glaciers’ Preservation and launches the Decade of Action on Cryospheric Science (2025–2034). These initiatives, aligned with World Water Day 2025 and World Day for Glaciers (March 21), focus directly on the vital connections between mountain glaciers, freshwater, and ocean ecosystems. They promote the “Source-to-Sea (S2S)” approach, which integrates water governance from glacial sources all the way to ocean outlets, acknowledging their ecological and hydrological continuity.

Today’s editorial will talk about water governance in India and the world. It will help with GS Paper I (Geography), GS Paper II (Policy Making) and GS Paper III (Environment).

_

Let’s learn!

Why in the News?

Scientists and decision-makers need to pay attention to the Source to Sea (S2S) approach.

What is the theme of World Water Day 2025?

  • Theme: Glacier Preservation
  • 2025 is also declared the International Year of Glaciers Preservation by the United Nations.
  • Marks the start of a Decade of Action on Cryospheric Science (2025-2034).

Why is it significant?

  • Crucial Source of Freshwater: Glaciers act as natural water reservoirs, supplying freshwater to millions downstream. Their preservation ensures sustained water availability for drinking, agriculture, and ecosystems. Eg: The Himalayan glaciers feed rivers like the Ganga and Brahmaputra, supporting millions of people in India.
  • Indicator of Climate Change: Glaciers are sensitive to global warming; their rapid melting signals climate change impacts. Protecting them helps monitor and mitigate broader environmental risks. Eg: Melting Himalayan glaciers contribute to changing river flows, affecting flood and drought patterns in South Asia.
  • Supports Sustainable Development: Preserving glaciers helps maintain mountain ecosystems and supports downstream communities dependent on glacier-fed waters for their livelihoods and economic activities. Eg: Alpine glaciers support mountain agriculture and tourism, critical to local economies in regions like Uttarakhand and Himachal Pradesh.

Why is the Source-to-Sea (S2S) approach important for global water governance?

  • Integrated Management of Water Systems: S2S treats freshwater and marine systems as a connected continuum, ensuring that actions upstream (rivers, lakes) consider their impact downstream (coastal and marine environments). Eg: Pollution control in river basins like the Ganges directly affects the health of the Bay of Bengal ecosystem.
  • Improves Coordination Across Jurisdictions: S2S promotes cooperation among multiple stakeholders and political jurisdictions, bridging fragmented governance to manage shared water resources effectively. Eg: The Manila Declaration encourages countries to work together on ridge-to-reef management to protect water quality from land to ocean.
  • Facilitates Sustainable Solutions for Water and Marine Challenges: By addressing the entire water cycle, S2S enables holistic strategies that tackle issues like pollution, water diversion, and habitat loss, benefiting both terrestrial and marine biodiversity. Eg: Initiatives under the SIWI Action Platform connect freshwater and marine experts to develop better water management practices globally.

What is the cryosphere? 

The cryosphere includes all frozen water parts of Earth, such as glaciers, snow, sea ice, and permafrost. It helps regulate the climate, reflects sunlight, and stores Earth’s freshwater.

How does the changing mountain cryosphere impact downstream water resources?

  • Altered Water Flow Patterns: Melting glaciers and shrinking snowpacks change the timing and volume of water flow downstream, leading to seasonal water shortages or floods. Eg: Reduced glacial melt in the Himalayas affects the flow of rivers like the Ganges, impacting water availability for millions.
  • Reduced Water Storage Capacity: Glaciers act as natural reservoirs, storing water during cold months and releasing it slowly. Their retreat means less buffering capacity during dry periods, causing water stress downstream. Eg: Declining glacier size in the Alps affects water supplies for European river basins in summer.
  • Increased Risk of Natural Hazards: Glacier melt can lead to the formation and sudden breach of glacial lakes, causing flash floods and damaging downstream ecosystems and communities. Eg: Glacial Lake Outburst Floods (GLOFs) in the Himalayas pose risks to villages and infrastructure along rivers like the Indus.

What are the key challenges India faces in managing its water resources? 

  • Groundwater Depletion: Over-extraction of groundwater for irrigation, industrial use, and domestic consumption has led to alarming depletion rates of aquifers. This poses a significant threat to long-term water availability and agricultural productivity. Eg, states like Punjab, Haryana, and Rajasthan report over 100% utilization of groundwater resources, leading to critical water scarcity.
  • Water Pollution: Water pollution from industrial effluents, untreated sewage, and agricultural runoff has made large quantities of freshwater unusable. According to the Central Pollution Control Board, more than 70% of India’s surface water is polluted, with rivers like the Ganga and Yamuna being majorly affected.
  • Climate Change and Erratic Weather Patterns: Changing rainfall patterns, prolonged droughts, and frequent floods induced by climate change are altering water availability. The Indian Meteorological Department has noted a decline in monsoon rainfall, which is critical for replenishing rivers, lakes, and groundwater reserves.

What are the steps taken by the Indian Government?

  • Formulation and Revision of National Water Policies: The government introduced the first National Water Policy in 1987, and since then, it has been periodically updated to address emerging challenges. The latest draft policies emphasize integrated water resource management and sustainability. Eg, the 2019 draft National Water Policy focuses on water conservation, efficient use, and equitable distribution.
  • Institutional Reforms and Coordination Bodies: Committees have been set up to improve water governance by restructuring key institutions. Eg, in 2015, a committee was formed to merge the Central Water Commission and Central Ground Water Board into a unified National Water Commission to foster better coordination and planning.
  • Promotion of Sustainable and Integrated Approaches: The government supports approaches like Source-to-Sea (S2S) management, which integrates land, freshwater, coastal, and marine resource management. Eg, pilot projects in the Indo-Gangetic basin and Delhi waterbodies are being explored under the S2S framework to address pollution and water quality comprehensively.

Way forward: 

  • Adopt Source-to-Sea (S2S) Approach Nationwide: Implement integrated water governance that connects glacial sources to coastal ecosystems, ensuring coordinated action across sectors and regions.
  • Strengthen Climate-Resilient Water Infrastructure: Invest in glacier monitoring, early warning systems, and sustainable groundwater management to adapt to climate-induced water variability and safeguard water security.

Is groundwater contamination high in India?

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Mains level: Challenges related to water resources;

Why in the News?

The Central Ground Water Board (CGWB) found that many states in India are facing a serious problem with high nitrate levels in groundwater.

What are the contaminants? 

The assessment of India’s groundwater quality has identified several significant contaminants, primarily driven by agricultural practices, industrial activities, and natural geological factors. The key contaminants include:

  • Nitrates: Excessive use of nitrogen-based fertilizers in agriculture leads to high levels of nitrates in groundwater. This is the most prevalent contaminant, with over 56% of India’s districts reporting nitrate levels exceeding the safe limit of 45 mg/l.
  • Fluoride: Fluoride contamination is a major concern, particularly in states like Rajasthan, Haryana, and Karnataka. Approximately 9.04% of tested groundwater samples had fluoride levels above the permissible limit of 1.5 mg/l.
  • Arsenic: Naturally occurring arsenic in certain geological formations poses serious health risks, particularly in alluvial plains where industrial activities may exacerbate contamination.
  • Uranium: Elevated uranium levels have been detected in several regions, with about 6.60% of samples exceeding the safe limit of 30 ppb (parts per billion). States like Rajasthan and Punjab report significant uranium contamination.
  • Iron: High concentrations of iron affect groundwater quality and can lead to aesthetic issues and potential health risks when consumed in large amounts.
  • Other Heavy Metals: Contaminants such as lead, cadmium, mercury, and chromium are also present due to industrial discharges and improper waste management.

What was the state of groundwater in 2024?

  • Overall Extraction Rate: The degree of groundwater extraction across the country was reported at approximately 60.4%, indicating that this level has remained relatively stable compared to previous years. This figure reflects the percentage of groundwater resources being utilized versus what is available for extraction.
  • Safe Blocks: About 73% of groundwater blocks were categorized as ‘safe,’ meaning they are adequately replenished to meet extraction demands. This represents a slight increase from previous assessments.
  • Recharge and Availability: Total annual groundwater recharge was noted to have decreased marginally from 449 BCM (Billion Cubic Meters) in 2023 to 446.90 BCM in 2024.
    • The annual extractable groundwater resources slightly declined from 407.21 BCM to 406.19 BCM.
  • Contamination Issues: Despite improvements in some areas, challenges remain, particularly with nitrate contamination, where 440 districts were identified as having excessive nitrate levels in their groundwater.

How are groundwater levels measured?

Groundwater levels are measured using a network established by the Central Ground Water Board (CGWB), which includes:

  • Observation Wells: Approximately 26,000 observation wells are used for manual measurements of groundwater levels.
  • Digital Monitoring: Since 2023, around 16,000 to 17,000 piezometers equipped with digital recorders have been installed to automatically measure and transmit groundwater levels to a centralized system for real-time monitoring.

What happens if nitrate presence is high in groundwater?

  • Health Risks: Elevated nitrate levels can cause methemoglobinemia, also known as “blue baby syndrome,” particularly in infants under six months old. This condition reduces the blood’s ability to carry oxygen, resulting in a bluish tint to the skin and potentially severe health complications if untreated.
  • Environmental Concerns: Excessive nitrates contribute to algal blooms in surface water bodies, which can deplete oxygen levels, harm aquatic ecosystems, and disrupt the balance of marine life.

Way forward: 

  • Sustainable Agricultural Practices: Promote the use of organic fertilizers, precision farming techniques, and regulated use of nitrogen-based fertilizers to minimize nitrate leaching into groundwater.
  • Strengthened Monitoring and Remediation: Expand digital groundwater monitoring networks, enforce strict industrial discharge regulations, and implement remediation techniques like bioremediation and constructed wetlands to mitigate contamination.

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Disaster Management
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Features of the Dam Safety Act, 2021

Why in the News?

The Supreme Court has criticized the Union government for its inaction in fully implementing the Dam Safety Act, 2021, nearly five years after its enactment.

What is the Dam Safety Act of 2021?

Details Enacted to ensure the structural and operational safety of over 5,700 large dams in India.

Objectives (Section 3):
• Prevent dam-related disasters by ensuring dam safety.
• Establish institutions for monitoring, maintenance, and emergency preparedness.
Structural Mandate
  • National Committee on Dam Safety (NCDS) (Sections 5–6): Chaired by the Chairperson of the Central Water Commission (CWC) and reconstituted every three years to develop policies, guidelines, and standards.
  • National Dam Safety Authority (NDSA) (Section 9): Implements NCDS guidelines, regulates dam safety standards, and resolves disputes between State Dam Safety Organizations (SDSOs) and dam owners.
  • State Committees on Dam Safety (SCDS) (Section 14): Provide state-level oversight.
  • State Dam Safety Organizations (SDSOs) (Section 15): Monitor and inspect dams at the state level, reporting to NDSA.
Other Provisions:

 
  • Responsibilities of Dam Owners (Section 38):  Form Dam Safety Units, prepare and implement Emergency Action Plans (EAPs), and conduct regular Comprehensive Safety Evaluations (CSEs).
  • Emergency Preparedness (Section 39):  Mandatory EAPs for rapid response in emergencies.
  • Penalties for Non-Compliance (Section 45):  Imprisonment up to two years, fines, or both for failing to comply with Act provisions.

Why is Dam Safety a priority concern in India?

  • Third-Highest Number of Dams Globally: India has over 4,407 large dams, following China and the USA.
  • Aging Dams: By 2025, over 1,115 dams will be more than 50 years old; By 2050, 4,250 dams will surpass 50 years of age, with 64 dams exceeding 150 years.
  • Decreasing Storage Capacity: Sedimentation reduces reservoir efficiency, affecting water availability for irrigation, drinking, and hydropower. Ex. Bhakra Dam has experienced 139.86% higher siltation rates than estimated, reducing its lifespan.
  • Structural Vulnerabilities: Poorly designed sedimentation management systems make many dams structurally weak over time. Extreme environmental events, such as floods, can exacerbate these vulnerabilities.
  • Lack of Data and Monitoring: Insufficient documentation of storage loss, sedimentation rates, and other critical metrics leads to a lack of preparedness.

Polavaram Project Controversy

Explained | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.
Note4Students

From UPSC perspective, the following things are important:

Mains level: Inter-state water dispute; Resource distribution;

Why in the News?

The Biju Janata Dal (BJD) has restarted its protest against the Polavaram multipurpose project in Andhra Pradesh, claiming it will flood large areas in Malkangiri, Odisha, displacing many tribal communities.

What were the recommendations by the Godavari Water Disputes Tribunal (GWDT) 1969?

The Godavari Water Disputes Tribunal (GWDT), was established to resolve water-sharing disputes concerning Godavari River water among the states of Andhra Pradesh, Maharashtra, and Madhya Pradesh (now Chhattisgarh). It made several key recommendations regarding the utilization of Godavari River water. Notable points include:

  • Water Allocation: The Tribunal allowed Andhra Pradesh to divert 80 TMC (thousand million cubic feet) of Godavari water at 75% dependability for irrigation and other uses, which could also substitute releases from the Nagarjunasagar project for the Krishna delta.
  • Inter-State Agreements: The Tribunal recognized various inter-state agreements that specified how water from the Godavari and its tributaries could be utilised, ensuring equitable distribution among the states involved.
  • Project Approvals: The GWDT endorsed the construction of projects like Polavaram, provided they adhered to specified Full Reservoir Levels (FRL) and operational guidelines.

What are the social and environmental impacts of the Polavaram Project?

  • Social Impact: The project is expected to displace over 150,000 people across approximately 276 villages, with many of these being tribal communities. For every five acres irrigated, one tribal family is projected to lose their land.
    • Infrastructure Strain: The project has faced funding challenges for rehabilitation efforts, leading to halted work on necessary infrastructure like canals, which could exacerbate social tensions among displaced populations.
  • Environmental Impact: The dam’s backwaters will submerge an estimated 3,731 hectares of forest land. The environmental impact assessments have raised concerns about ecosystem disruption, including increased vulnerability to erosion and regional landslides.

How is the project being managed politically and administratively?

  • National Project Status: Declared a national project under the Andhra Pradesh Reorganisation Act of 2014, the Central Government is responsible for executing the project while ensuring compliance with environmental and rehabilitation norms.
  • Polavaram Project Authority: A governing body has been established to oversee project execution, comprising representatives from both state and central governments. This authority is tasked with ensuring timely execution and adherence to regulatory requirements.
  • Political Dynamics: The project has become a focal point for regional politics, particularly as parties like the BJD leverage opposition against it to bolster their regional identity amidst changing political landscapes in states like Odisha.

What are the legal and regulatory challenges faced by the Polavaram Project?

  • Ongoing Litigation: Multiple states have challenged the project in court on grounds of inadequate environmental assessments and potential adverse impacts on their territories. Legal disputes have persisted since at least 2011, complicating project timelines.
  • Regulatory Compliance Issues: Environmental clearances for the project have been contentious, particularly following changes in flood situation estimates that were not incorporated into updated designs. This has raised questions about compliance with earlier environmental impact assessments conducted in 2005.
  • Funding Challenges: Financial constraints have hindered progress on rehabilitation efforts for displaced populations, leading to further legal scrutiny regarding compliance with social justice norms and commitments made during project approval processes.

Way forward: 

  • Comprehensive Impact Assessment and Mitigation: Conduct updated environmental and social impact assessments, including backwater studies, and implement robust mitigation measures for displaced populations, ensuring compliance with legal and regulatory frameworks.
  • Strengthen Inter-State Collaboration: Establish a transparent and inclusive mechanism involving all affected states to address concerns, promote equitable resource sharing, and expedite the resolution of legal and administrative challenges.

Why climate change poses an existential threat to Panama Canal?   

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Mains level: Impact of Climate change on Panama Canal;

Why in the News?

The Panama Canal, which links the Atlantic and Pacific Oceans through the Isthmus of Panama, opened to ships 110 years ago. Now, it is facing a serious threat to its existence.

System of Water Elevators

  • The Panama Canal utilizes a sophisticated lock system that functions as water elevators, allowing ships to navigate the elevation difference between the Atlantic and Pacific Oceans. This system is essential because the two oceans are at different elevations, with the Pacific being slightly higher.

Operation of the Locks

  1. Ship Enters: A ship approaches the first lock chamber, which is at sea level. The gate opens to allow the ship into the chamber and then closes behind it.
  2. Water Level Adjustment: The valve between the first and second chamber (at a higher elevation) is opened, allowing water to flow into the first chamber from the adjacent higher chamber. This increases the water level in the first chamber.
  3. Transition: Once the water levels between the two chambers are equalized, the gate between them opens, allowing the ship to move into the next chamber. This process is repeated until the ship reaches the desired elevation of 85 feet at Gatun Lake.
  4. Lowering: The reverse process occurs when lowering ships back to sea level at the other end of the canal.

Note: Each passage requires over 50 million gallons (approximately 200 million liters) of freshwater, primarily sourced from Lake Gatun, which is vital for the canal’s operation.

Threat of Climate Change

  • Recent droughts have led to significantly lower water levels in Lake Gatun because droughts were exacerbated by climate change and the El Niño phenomenon, which have led to significantly reduced water levels in the lake.
  • In 2023, rainfall was 43% lower than average, making it one of the driest years on record for the region.  which reduced the number of ships able to transit the canal.
  • In December, traffic dropped to as low as 22 ships per day, highlighting the vulnerability of the canal to climatic variations.

Contentious Solution

  • Proposed Dam: This $1.6 billion project aims to create an additional water source for the canal on the Rio Indio, potentially securing water availability for the next 50 years. However, it has sparked controversy due to its social implications.
    • Displacement Issues: The dam would flood the homes of approximately 2,000 residents, predominantly from lower socio-economic backgrounds, forcing them to relocate and lose their livelihoods. This raises significant ethical concerns regarding the balance between infrastructure needs and the rights of affected communities

Conclusion:

Before proceeding with the Rio Indio dam project, engage in thorough consultations with the affected communities, ensuring their voices are heard in the decision-making process. Need to develop a fair compensation and resettlement plan that prioritizes the socio-economic well-being of displaced residents, offering alternative livelihoods and housing options to minimize the negative impact on vulnerable populations.

Do you know about another elevation-based canal system? 

  1. Kiel Canal (Germany): The Kiel Canal features locks that raise and lower vessels to navigate the elevation differences between the North Sea and the Baltic Sea. It is one of the busiest artificial waterways in the world.
  2. Welland Canal (Canada): This canal connects Lake Ontario and Lake Erie and includes a series of locks that lift ships approximately 43 meters (141 feet) to bypass Niagara Falls. It is an essential part of the Great Lakes shipping route.

Trade from Panama Canal: 

  • The Panama Canal moves roughly $270 billion worth of cargo annually, which is the trade route taken by 40% of all U.S. container traffic alone. It handles about 5% of all global maritime trade.

Does India have laws on the movement of ballast water?

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: What is Ballast Water?

Mains level: Serious concern due to Ballast Water;

Why in the News?

The TN Water Resources Department (WRD) has informed the National Green Tribunal that it has requested ₹160 crore from Kamarajar Port in Ennore, Tamil Nadu, to address the removal of invasive mussels along the coast near the port.

  • The WRD has accused Kamarajar Port of being primarily responsible for the spread of this invasive species due to its failure to regulate ballast water from ships.

What is Ballast Water?

  • Ballast water is fresh or saltwater held in the ballast tanks of ships. It is used to provide stability and maneuverability during a voyage, especially when a ship is not carrying enough cargo or when additional stability is required due to rough seas.
  • Ballast water can carry a variety of biological materials, including bacteria, microbes, and small invertebrates. When discharged at a new location, this water can introduce non-native species into local ecosystems, potentially leading to ecological imbalances.

How Serious is the Problem?

  • Invasive Species in India: Scientists have recorded nearly 30 invasive species entering Indian waters through ship ballast water, with the charru mussel (Mytella strigata) being one of the most harmful. This species has replaced native species in critical habitats like Pulicat Lake in Tamil Nadu.
  • Ecological Impact: The introduction of invasive species can disrupt local ecosystems, outcompete native organisms, and significantly affect biodiversity. The charru mussel has a high survival rate and prolific reproduction, exacerbating its impact on marine environments.
  • Economic Consequences: The proliferation of invasive species can hinder fishing activities and affect the livelihoods of local communities dependent on marine resources.

What are Global Regulations?

  • Ballast Water Management (BWM) Convention: The International Maritime Organization (IMO) adopted the BWM Convention, which came into force in 2017. This convention aims to prevent the spread of harmful aquatic organisms and pathogens through ballast water.
  • Under the BWM Convention, ships must manage their ballast water to ensure that aquatic organisms and pathogens are removed or rendered harmless before discharge.
  • Compliance: Countries like Australia and New Zealand have stringent regulations to prevent ballast water from damaging their marine ecosystems, including rigorous checks of ballast water management systems.

What is India’s Position?

  • As of July 2023, India has not signed the BWM Convention, meaning there are no obligations for ships calling at Indian ports to comply with its regulations. This lack of participation raises concerns about the unchecked discharge of ballast water.
  • While other maritime regulations apply in Indian ports but the discharge of ballast water is not subject to checks or regulations, leading to potential ecological risks.

Way forward: 

  • Adopt and Implement the BWM Convention: India should consider ratifying the Ballast Water Management (BWM) Convention to align with international standards.
  • Strengthen Domestic Regulations and Awareness: Even before ratifying the BWM Convention, India can introduce national legislation to regulate ballast water discharge in its ports.

  • This legislation, instrumental in establishing central and state pollution control boards (CPCB and SPCBs), undergoes significant modifications under the proposed Bill, primarily concerning penalties and regulatory mechanisms.

About Water (Prevention and Control of Pollution) Act, 1974

Description
Objective To prevent and control water pollution and maintain or restore the wholesomeness of water resources
Applicability Applies to the entire territory of India, including streams, rivers, lakes, inland water bodies, subterranean waters, and territorial waters of the country
Establishments Establishes Central Pollution Control Board (CPCB) at the central level and State Pollution Control Boards (SPCBs) at the state level
Standards and Regulations Empowers Pollution Control Boards to prescribe standards for the discharge of pollutants and quality of water for various purposes
Consent Mechanism Requires industries and establishments to obtain prior consent from Pollution Control Boards before discharging pollutants into water bodies
Penalties and Enforcement Specifies penalties for contravention, including fines and imprisonment; authorizes officers to inspect premises, take samples, and issue directives for compliance

 

Key Amendments Proposed:

[A] Consent Exemptions for Establishing Industries

  • Prior Consent Requirement: Currently, the Act mandates obtaining consent from SPCBs for setting up industries or treatment plants likely to discharge sewage into water bodies.
  • Bill Provisions: The Bill empowers the central government, in consultation with the CPCB, to exempt certain industrial categories from seeking consent. It also authorizes the central government to issue guidelines for the grant, refusal, or cancellation of such consent.
  • Penalties: Violating the consent requirement or tampering with monitoring devices incurs penalties ranging from Rs 10,000 to Rs 15 lakh.

[B] Chairman of State Board

  • Nomination Process: While the Act vests state governments with the authority to nominate SPCB chairpersons, the Bill introduces central government-prescribed nomination procedures and terms of service.

[C] Discharge of Polluting Matter

  • Regulatory Measures: The SPCBs can issue directives to halt activities leading to the discharge of harmful substances into water bodies.
  • Penalties: Contraventions against pollution standards attract penalties ranging from Rs 10,000 to Rs 15 lakh, replacing the previous imprisonment provisions.
  • Amended Provisions: The Bill replaces imprisonment with penalties between Rs 10,000 and Rs 15 lakh for unspecified offences under the Act.

[D] Adjudication Mechanism

  • Appointment of Officers: It allows the central government to designate adjudication officers, with appeals against their decisions to be lodged before the National Green Tribunal.

From UPSC perspective, the following things are important:

Prelims level: Har Ghar Jal Initiative

Mains level: NA

har ghar jal

Central Idea

  • The Har Ghar Jal initiative, part of the Jal Jeevan Mission, aims to provide potable water connections to all rural households in India by 2024.
  • However, multiple sources and data analysis indicate that the initiative is likely to fall short of its target, with only 75% of village homes expected to have drinking water taps by April 2024.

Har Ghar Jal Initiative: A quick recap

  • Har Ghar Jal (translation: Water to Every Household) is a scheme initiated by the Ministry of Jal Shakti under Jal Jeevan Mission in 2019.
  • It aimed to provide tap water to every rural household by 2024.
  • Finance Minister announced the scheme in 2019 Union budget.
  • In August 2022, Goa and Dadra and Nagar Haveli and Daman and Diu became the first ‘Har Ghar Jal’ certified State and UT respectively with 100% tap-water access.
  • As of January 2023, other states and UTs Gujarat, Puducherry and Telangana have also achieved 100% tap-water access.
  • Since its inception, the scheme has significantly improved household clean tap water availability in India.

Challenges Faced by the Initiative

  • Delayed Progress: The COVID-19 pandemic and a lack of qualified manpower in states have contributed to the delayed implementation of the scheme.
  • Shortages of Essential Materials: The ongoing Russia-Ukraine war resulted in major shortages of steel and cement, crucial for manufacturing and connecting metal pipes, leading to delays and price revisions.
  • Manpower Shortage: Some states faced challenges in finding skilled workers to construct tanks, cisterns, and water connections of acceptable quality.
  • State-Specific Issues: Certain states, such as Rajasthan, face challenges in ensuring the availability of water, while West Bengal and Kerala struggle with water contamination issues.
  • Certification Gap: While the states report high coverage figures, there is a significant gap between reported and verified connections.

Expectations and Progress

  • Revised Expectations: The officials now expect about 75% of households to be covered by March 2024 and 80% by December 2024.
  • Work Yet to Begin: Around one crore households (5% of the total) have not even begun work under the scheme.
  • Timeframe Challenges: Connecting all households in villages that already have access to water sources takes an average of eight months, making it unlikely to finish in some places before 2025-26.

Political Factors and Connection Status

  • Political Angle: Some states, like Bihar and Telangana, did not rely on central funds and did not certify their connection status due to political considerations.
  • Significance of Certification: “Har Ghar Jal” villages certified as 100% compliant prominently display the images of the Prime Minister and Chief Minister, especially if Central funds were used.

Arsenic Contamination in India

Prelims Only | Governance | Mains Paper 2: Health & Education
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Arsenic Poisoning

Mains level: Not Much

arsenic

Central Idea: A recent peer-reviewed study suggests that even low levels of arsenic consumption can affect cognitive function in children, adolescents, and young adults.

Arsenic Contamination

  • Arsenic is a highly toxic element naturally present in the environment.
  • Contaminated water, particularly groundwater, is a major source of arsenic exposure.
  • Long-term arsenic exposure can lead to various health issues, including cancer, skin lesions, cardiovascular disease, and negative impacts on cognitive development.

Menace in India

  • Arsenic contamination in groundwater is one of the most crippling issues in the drinking water scenario of India.
  • According to the latest report of the Central Ground Water Board (CGWB), 21 states across the country have pockets with arsenic levels higher than the BIS stipulated permissible limit of 0.01 milligram per litre (mg/l).
  • The states along the Ganga-Brahmaputra-Meghna (GBM) river basin — Uttar Pradesh, Bihar, Jharkhand, West Bengal and Assam — are the worst affected by this human-amplified geogenic occurrence.
  • In India, arsenic contamination was first officially confirmed in West Bengal in 1983.
  • Close to four decades after its detection, the scenario has worsened.
  • About 9.6 million people in West Bengal, 1.6 million in Assam, 1.2 million in Bihar, 0.5 million in Uttar Pradesh and 0.013 million in Jharkhand are at immediate risk from arsenic contamination in groundwater.

Key findings of the recent study

(1) Arsenic impact on behaviour

  • The study found that individuals exposed to arsenic had reduced grey matter and weaker connections within key regions of the brain associated with cognitive functions.
  • Chronic exposure to arsenic could have significant consequences at a population level, leading to increased school failures, diminished economic productivity, and higher risks of criminal and antisocial behavior.

(2) Arsenic Exposure and Socioeconomic Factors

  • As previous studies have shown, arsenic exposure is particularly harmful to the poor.
  • The recent study reaffirms that economically and nutritionally disadvantaged individuals experience greater cognitive impairment from arsenic exposure.
  • The impact of arsenic on impairing cognition is more pronounced at a collective level rather than at an individual level.

Government Initiatives to address Arsenic Contamination

  • Governments in Bihar and West Bengal have taken steps to address arsenic contamination since the 1990s.
  • Strategies include promoting piped water access, installing arsenic removal plants, and encouraging groundwater extraction from deeper aquifers with lower arsenic levels.
  • The goal is to minimize arsenic exposure and mitigate its health impacts in affected regions.

Possible solutions

Some of the management options include

  • Uses of surface water sources
  • Exploring and harnessing alternate arsenic-free aquifer
  • Removal of arsenic from groundwater using arsenic treatment plants/filters
  • Adopting rainwater harvesting/ watershed management practices.

Groundwater Extraction and Land Subsidence

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: NA

Mains level: Groundwater exploitation issue

groundwater

Central Idea: Groundwater extraction in northwestern India, including Punjab, Haryana, Delhi, and Faridabad, has led to land subsidence and structural damage.

What is Groundwater?

  • Groundwater is the water found underground in the cracks and spaces in soil, sand and rock.
  • It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
  • Aquifers are typically made up of gravel, sand, sandstone, or fractured rock, like limestone.
  • Water can move through these materials because they have large connected spaces that make them permeable.
  • Aquifers, hand-dug wells, and artesian wells are different types of sources of groundwater.

Reasons for Depletion

  • Increased demand for water for domestic, industrial and agricultural needs and limited surface water resources lead to the over-exploitation of groundwater resources.
  • Limited storage facilities owing to the hard rock terrain, along with the added disadvantage of lack of rainfall, especially in central Indian states.
  • Green Revolution enabled water-intensive crops to be grown in drought-prone/ water deficit regions, leading to over-extraction of groundwater.
  • Frequent pumping of water from the ground without waiting for its replenishment leads to quick depletion.
  • Subsidies on electricity and high MSP for water-intensive crops is also leading reasons for depletion.
  • Inadequate regulation of groundwater laws encourages the exhaustion of groundwater resources without any penalty.
  • Deforestation, unscientific methods of agriculture, chemical effluents from industries, and lack of sanitation also lead to pollution of groundwater, making it unusable.
  • Natural causes include uneven rainfall and climate change that are hindering the process of groundwater recharge.

Impact of groundwater depletion

  • Lowering of the water table: Groundwater depletion may lower the water table leading to difficulty in extracting groundwater for usage.
  • Reduction of water in streams and lakes: A substantial amount of the water flowing in rivers comes from seepage of groundwater into the streambed. Depletion of groundwater levels may reduce water flow in such streams.
  • Subsidence of land: Groundwater often provides support to the soil. When this balance is altered by taking out the water, the soil collapses, compacts, and drops leading to subsidence of land.
  • Increased cost for water extraction: As the depleting groundwater levels lower the water table, the user has to delve deep to extract water. This will increase the cost of water extraction.

Mechanism of Land Subsidence

  • The relationship between excessive groundwater extraction and land subsidence became evident through the analysis of data from Gravity Recovery and Climate Experiment (GRACE) satellites.
  • Excessive groundwater withdrawal, coupled with limited monsoon rain, has resulted in critically low groundwater levels in the region.
  • Land subsidence occurs when underlying aquifers, which are deep water channels storing percolated water, are not adequately recharged.
  • The depletion of aquifers causes the layers of soil and rock above them to sink gradually.
  • This sinking of soil is similar to “soil settlement” observed in mining operations.

Regulation of Groundwater in India

(1) Central Ground Water Authority (CGWA)

  • It has the mandate of regulating groundwater development and management in the country.
  • It is constituted under the Environment (Protection) Act of 1986.
  • CGWA issues advisories, public notices and grant No Objection Certificates (NOC) for ground water withdrawal.

(2) National Aquifer Mapping and Management Programme (NAQUIM)

  • The NAQUIM is an initiative of the Ministry of Jal Shakti for mapping and managing the entire aquifer systems in the country.
  • It maintains the Hydrological Map of India.

(3) Atal Bhujal Yojana 

  • It is a Central Sector Scheme, for sustainable management of groundwater resources with community participation in water-stressed blocks.

Way Forward

  • Routine survey: There should be regular assessment of groundwater levels to ensure that adequate data is available for formulating policies and devising new techniques.
  • Assessment of land use pattern: Studies should be carried out to assess land use and the proportion of agricultural land falling under overt-exploited units.
  • Changes in farming methods: To improve the water table in those areas where it is being overused, on-farm water management techniques and improved irrigation methods should be adopted.
  • Reforms in power supply subsidies: The agricultural power-pricing structure needs to be revamped as the flat rate of electricity adversely affects the use of groundwater.
  • Monitoring extraction: There should be a policy in place to monitor the excessive exploitation of groundwater resources to ensure long-term sustainability.

Indian Sludge Shows High Fertilizer Potential: First Study Reveals

Prelims Only | Governance | Mains Paper 2: Government Scheme/Policies
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Namami Gange Program

Mains level: Read the attached story

Central Idea: The article discusses the results of an analysis of the sludge found in Indian sewage treatment plants (STP) that were set up to treat polluted water from the Ganga under National Mission for Clean Ganga.

About National Mission for Clean Ganga

Description
Launch 2014
Aim Cleaning and rejuvenating the Ganga river
Interventions Development of sewage treatment infrastructure, riverfront development, and public awareness campaigns
Approach River basin approach, identifying pollution hotspots and implementing targeted interventions
Implementing Agency NMCG
Responsibilities Coordinating efforts across stakeholders, including state governments, municipalities, and civil society organizations
Objective Improve water quality and ensure ecological and socio-economic sustainability of the Ganga river

 

Sludge classification

  • India doesn’t yet have standards classifying sludge as class A or B.
  • Treated sludge can be classified as class A or class B, as per the standards of the United States Environment Protection Agency.
  1. Class A sludge: It is safe to be disposed of in the open and useful as organic fertilizer.
  2. Class B sludge: It can be used in restricted agricultural applications, with the edible parts of the crop not exposed to the sludge-mixed soil, and animals and people not come into extensive contact.

Current sludge disposal practices

  • Currently, those awarded contracts for developing and maintaining STPs under the Namami Ganga Mission are also apportioned land for disposing off sludge.
  • However, the sludge is rarely treated, and during rains, it often makes its way back into rivers and local water sources.

Study’s findings

  • The sludge analysed after drying fell into the class B category.
  • Nitrogen and phosphorus levels were higher than those recommended by India’s fertilizer standards, but potassium levels of some sludges were less than recommended.
  • The degree of pathogens, as well as heavy metal contamination, was above the recommended fertilizer standards.
  • The calorific value of sludge ranged from 1,000-3,500 kcal/kg, which is lower than the average calorific value of Indian coal.

Recommendations to improve sludge quality

  • The report recommends storing the sludge for at least three months to kill pathogens and blending it with cattle manure and husk or local soil to reduce heavy metal.
  • However, this would still put it in class B, and converting it into grade A sludge would require far more extensive treatment.

Jal Shakti Ministry plans network of Groundwater Sensors

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Groundwater in India

Mains level: Read the attached story

groundwater

Central Idea: The Jal Shakti Ministry is working on an ambitious plan to deploy a vast network of groundwater sensors to continuously relay information on groundwater levels and contamination.

What is Groundwater?

  • Groundwater is the water found underground in the cracks and spaces in soil, sand and rock.
  • It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
  • Aquifers are typically made up of gravel, sand, sandstone, or fractured rock, like limestone.
  • Water can move through these materials because they have large connected spaces that make them permeable.
  • Aquifers, hand-dug wells, and artesian wells are different types of sources of groundwater.

Sensors-based Groundwater Monitoring

  • Under this new initiative, around 16,000-17,000 digital water level recorders will be connected to piezometers in the wells to transmit information digitally.
  • In the next three years, the CGWB aims to increase its network from the existing 26,000 to about 40,000.
  • When combined with similar networks possessed by other institutions, India will have about 67,000 digitally recordable units to monitor groundwater dynamics.

Significance of the move

  • This would make groundwater visible much the same way as air quality and meteorological variables
  • The information will be publicly accessible.
  • It will potentially provide groundwater forecasts to farmers that would be useful for sowing and updated advisories that can influence groundwater extraction policies by states

Why monitor groundwater?

  • Nitrate contamination – a result of the use of nitrogenous fertilizers – has been observed in some regions
  • Groundwater contamination, mostly “geogenic” (natural), hasn’t significantly changed over the years.
  • But nitrate contamination and fluoride and arsenic contamination have been observed in some regions and states.

Present system of monitoring

  • The Central Groundwater Board currently relies on a network of about 26 thousand groundwater observation wells.
  • It requires technicians to manually measure the state of groundwater in a region.

Groundwater Extraction in India

  • The total annual groundwater recharge in the country has been assessed as 437.60 billion cubic meters (BCM)
  • The annual extractable groundwater resource has been assessed as 398.08 bcm, with actual extraction of 239.16 bcm
  • The average stage of groundwater extraction for the country as a whole works out to be about 60.08%, and anything above 70% is considered “critical”

The Ministry of Jal Shakti has recently released the report of the first census of waterbodies in India.

Waterbodies Census

  • It is the first ever process of conducting a comprehensive survey of all the waterbodies in a particular region or country.
  • The census aims to identify and classify different types of waterbodies like ponds, tanks, lakes, and reservoirs, among others.
  • The information can help in the development of strategies for their conservation and management.

Major highlight: Definition of Waterbodies

  • The census defines a waterbody as a unit bounded on all sides that is used for storing water for various purposes.
  • These units can be either natural or man-made and may or may not have masonry work.
  • Waterbodies are used for a variety of purposes, such as irrigation, industrial use, pisciculture, domestic and drinking water supply, recreation, religious purposes, and groundwater recharge.
  • The report states that any structure that accumulates water from ice-melt, streams, springs, rain or drainage of water from residential or other areas or stores water by diversion from a stream, nala or river is also considered a waterbody.

Key facts: Distribution of Waterbodies

According to the report, India has 24.24 lakh water bodies like ponds, tanks, and lakes, with West Bengal having the highest number (7.47 lakh) and Sikkim having the least number (134).

Waterbody Type Percentage of Total Waterbodies Number of Waterbodies
Ponds 59.5% 14,42,993
Tanks 15.7% 3,81,805
Reservoirs 12.1% 2,92,280
Water Conservation Schemes/Percolation Tanks/Check Dams 9.3% 2,26,217
Lakes 0.9% 22,361
Others 2.5% 58,884

 

State-Wise Distribution of Waterbodies

  • The report highlights that West Bengal has the highest number of ponds and reservoirs, while Andhra Pradesh has the highest number of tanks.
  • Tamil Nadu has the highest number of lakes, and Maharashtra is the leading state with water conservation schemes.
  • South 24 Parganas district in West Bengal has been ranked as the top district having the highest (3.55 lakh) number of waterbodies across the country.

Issues highlighted: Encroachment of Waterbodies

  • Total 1.6% of waterbodies reported to be encroached
  • 4% of encroached waterbodies in rural areas, 4.6% in urban areas
  • 8% of encroached waterbodies have less than 25% area under encroachment
  • 8% of waterbodies have more than 75% area under encroachment

Conclusion

  • The census provides a comprehensive overview of the distribution of waterbodies in India, highlighting the states and districts with the highest number of waterbodies.
  • The data on encroachment of waterbodies can help in identifying areas where conservation efforts are needed to protect these valuable resources.

International Water Action Conference and Voluntary Commitments

op-ed snap | Enviro & Biodiversity | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India
Note4Students

From UPSC perspective, the following things are important:

Prelims level: UN Water Action Conference

Mains level: Water agenda, voluntary commitments and challenges

Conference

Central Idea

  • The International Water Action Conference held by the United Nations in March 2023, which resulted in over 670 commitments from various governments, multilateral institutions, businesses, and non-governmental organizations to address water security issues. There are implications of these commitments which needs to be examined the challenges associated with achieving universal, safe, affordable, and equitable access to water in line with SDG 6.

The Water Action Conference and its objective

  • First UN conference on freshwater: The Water Action Conference held in March 2023 was the first UN conference on freshwater in almost 50 years.
  • Aims to advance water agenda and achieve SDG 6: The conference aimed to review the Water Action Decade 2018-2028, which aims to advance the water agenda and achieve SDG 6, sustainable management of water and sanitation for all.

Themes of the conference

The Conference has five themes that support the SDG 6 Global Acceleration Framework:

  1. Water for Health: Access to ‘WASH’ (Global Water, Sanitation, & Hygiene) including the Human Rights to Safe Drinking Water and Sanitation
  2. Water for Sustainable Development: Valuing water, the water-energy-food nexus and sustainable economic and urban development.
  3. Water for Climate, Resilience and Environment: Source to sea, biodiversity, climate, resilience and disaster risk reduction.
  4. Water for Cooperation: Transboundary and international water cooperation, cross sectoral cooperation and water across the 2030 Agenda.
  5. Water Action Decade: Accelerating the implementation of the objectives of the Decade for Action, including through the UN Secretary-General’s Action Plan.

Conference

What is Water Action Decade (2018–2028)?

  • In December 2016, the United Nations General Assembly unanimously adopted the resolution International Decade (2018–2028) for Action Water for Sustainable Development to help put a greater focus on water during ten years.
  • It aims to advance the water agenda by energizing existing programs and projects and inspiring water action to achieve the 2030 Agenda, in particular, Sustainable Development Goal 6 (SDG 6), which envisions the sustainable management of water and sanitation for all.
  • The initiative focuses on promoting action-oriented partnerships to improve water resources management, water-use efficiency, and access to safe drinking water and sanitation services. The Decade aims to create a platform for sharing knowledge and experiences, promoting innovation, and building capacity for sustainable water management.

The International Water Action Agenda and commitments made

  • International Water Action Agenda: The conference resulted in the international Water Action Agenda, to which over 670 commitments were made by governments, multilateral institutions, businesses, and non-governmental organizations to address water security issues.
  • Commitments are voluntary: Nearly 164 governments and 75 multilateral organizations made commitments, but these commitments are voluntary and legally non-binding.

Implications of commitments made

  • The commitments embodied in the Water Action Agenda must be scrutinized to see whether they will yield universal, safe, affordable, and equitable access to water that is consistent with SDG 6.
  • Meeting this target by 2030 will require capital expenditures of $114 billion per year.
  • The recurring operations and maintenance for basic water and sanitation service (WASH) costs are estimated to rise from about $4 billion to over $30 billion per year by 2030.

Conference

Challenges associated with achieving SDG 6

  • Funding: Funding from regional, national, and international sources prioritizes new water infrastructure rather than water maintenance services, resulting in decreased service for water customers.
  • Investment: The investment required would require valuing water, which in turn requires robust water measurement and accounting.
  • Limitations: There are serious limitations in our knowledge about the volume, flux and quality of water in lakes, rivers, soils and aquifers. There are huge gaps in water usage data.

India’s commitments and challenges

  • India made two significant commitments at the conference:
  1. An investment of $240 billion in the water sector and
  2. Efforts to restore groundwater levels.
  • However, groundwater extraction in India increased from 58% to 63% between 2004-17, further exacerbated by climate change resulting in intermittent rainfall, which further undermines the recharge potential.
  • The revised Groundwater Bill 2017 vests State groundwater boards with creating laws, managing water allocation and other relevant issues.
  • The State boards are understaffed, and lack in expertise and prioritizing socio-political conflicts over groundwater resources.

Facts for prelims

Purpose of the conference

  • International conferences on water aim to better align activities by governments, companies, NGOs, and funders around a few grand challenges.
  • They help countries learn from the experiences of others, transfer technology, and invest.
  • Water problems tend to be local and need local solutions, so there is a challenge of mobilizing globally to solve local water problems.

Water challenges discussed

water

  • While access to safe drinking water and sanitation is challenging, extending services to underserved populations is relatively uncontroversial.
  • However, improving access to water and sanitation no longer translates directly to sustained access.
  • The water problem is no longer about access to water and sanitation; the remaining SDG 6 targets address the need to sustain agriculture, industry, and natural ecosystems.

Outcomes of the 2023 Conference

  • The conference’s proceedings resulted in a lot of talk, fragmented discussions, and no binding commitments.
  • There were 713 diverse voluntary commitments by philanthropic donors, governments, corporations, and NGOs, with 120 relevant to India.
  • Commitments included a $50-billion commitment from the Indian government to improve rural drinking water services under its Jal Jeevan Mission.

Examples of Commitments

  • Technology: Specific innovations in wastewater treatment or solar treatment of water in remote areas, and a number of proposals for incubation platforms.
  • Data and Models: Cost-effective approaches to data-generation included sensors and satellite data. Other efforts offered data analysis tools.
  • Knowledge Sharing: One useful tool was the W12+ Blueprint, a UNESCO platform that hosts city profiles and case studies of programs, technologies, policies that addresses common water security challenges.
  • Capacity Building: Efforts offered to help marginalized communities and women understand how to exercise their rights.
  • Civil Society: Platforms for collective action by civil society groups lobbying for changes in regulations.
  • Environmental, Social, and Corporate Governance: The conference concluded that effective water governance hinges on these broad areas, and weaving them into the Water Action Agenda is a step.

Uranium Contamination in Groundwater

op-ed snap | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Uranium contamination, causes and effects

Mains level: Groundwater pollution

Groundwater

Context

  • The most recent report on the state of groundwater released by the Central Groundwater Board. It revealed that the twelve Indian states have uranium levels beyond permissible limits in their groundwater. Uranium concentrations in the country’s shallow groundwater range from 0-532 parts per billion (ppb), according to the document titled Groundwater yearbook 2021-2022 released in January, 2023.

What is a Safe level of uranium in groundwater?

  • The safe levels for uranium in groundwater in India are 30 ppb as prescribed by the Bureau of Indian Standards (BIS) and the World Health Organization (WHO).
  • The safe level of 30 µg/L is established to minimize the risk of these health effects. However, it should be noted that long-term exposure to even low levels of uranium can also cause health problems.

Crack Prelims 2023! Talk to our Rankers

Findings of the report

  • No presence in Kerala: Uranium concentration is found to be within safe limits in 13 states and none of the samples collected from Kerala had its presence.
  • Punjab worse affected: Punjab is the worst-affected state in terms of the percentage of wells found to have uranium concentration of more than 30 ppb, the safe level. Nearly 29 per cent, or about three in every 10 wells tested in Punjab, is contaminated with uranium. Uranium presence in Punjab’s groundwater is found to be 17.7 times more than the safe limit prescribed by WHO. The concentration of the element was also highest in the state, with 532 ppb.
  • Haryana stands second: Haryana is the second state in terms of uranium prevalence in groundwater. The state also recorded the second-highest concentration of uranium in the country, with 518 ppb or 17.3 times the WHO-prescribed safe limit.
  • Uttar Pradesh third largest in terms of uranium concentration: The state was the third-highest in terms of uranium concentration, with 532 ppb or 7.9 times more than the safe limit. For example, 9.2 per cent of the samples from Uttar Pradesh had a high concentration of uranium.
  • Localised pockets of other states: Uranium concentration was found to be higher than the threshold level in localised pockets of seven other states Madhya Pradesh, Tamil Nadu, Chhattisgarh, Gujarat, Odisha, Telangana and Bihar.

Groundwater

Uranium: A toxic element

  • Uranium is a nephrotoxic element, which means people dependent on groundwater containing the element are at a higher risk of impaired renal function and kidney disease.
  • Exposure to uranium may also lead to other adverse health impacts, including bone toxicity and problems such as neurological effects, reproductive and developmental effects, and immune system effects.
  • Ingestion of large amounts of uranium can lead to immediate health effects such as nausea, vomiting, and diarrhoea. Inhalation of uranium dust or fumes can cause lung irritation and damage, including lung cancer.

Groundwater

Causes of contamination

  • Geogenic plus anthropogenic: Geogenic processes are responsible for uranium contamination, but the overexploitation of groundwater can also be a reason for it.
  • High concentration largely due to natural uranium content: High levels of uranium are largely due to natural uranium content in aquifer rocks, oxidation state and groundwater chemistry, noted researchers from Duke University.
  • High bicarbonate levels: Extreme bicarbonate levels were also found at the sites with high uranium levels. Bicarbonates help to bring the uranium out of the source rocks and is a reason for the high occurrence of the element, said Rachel Coyte, the lead author of the study.
  • Human-made causes too be behind this: Groundwater-table decline, nitrate pollution and over-exploitation of groundwater from irrigation further exacerbate uranium mobilisation, said the study.
  • Overexploitation of groundwater: Overexploitation of groundwater resources is likely to be one of the reasons for uranium and other geogenic contaminants, including arsenic and fluoride, according to the BARC study published in 2021.

Groundwater

Reverse osmosis could be a probable solution

  • Reverse osmosis (RO) is a way to purify water.
  • It uses a special membrane to filter out impurities, such as minerals and other dissolved contaminants, including toxic elements such as uranium.
  • The water is forced through the membrane by applying pressure, leaving behind the impurities and creating clean, purified water on the other side.
  • The impurities are removed by the membrane and the clean water is collected.

Did you know?

  • BARC has conducted studies on the removal of uranium from drinking water using a hybrid membrane technique.
  • Field studies are also being carried out in a few districts of Punjab based on RO technique at a village level to provide potable water, stated the BARC researchers.

Conclusion

  • Uranium contamination has been attributed to geogenic processes coupled with the overexploitation of groundwater in the country. This assessment of uranium contamination in groundwater across India highlights the need for an urgent response. Reverse osmosis (RO) is one of the latest membrane-based technologies used in water purification systems to remove uranium could be a solution.

Mains question

Q. Almost half of India’s states have uranium levels in their groundwater above permissible limits. Highlight the causes and effects of uranium contamination in groundwater.

The great Indian thirst: The story of India’s water stress

op-ed snap | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: various water reports

Mains level: water conservation

water stressContext

  • United Nations World Water Development Report of 2022 has expressed global concern over the sharp rise in freshwater withdrawal from streams, lakes, aquifers and human made reservoirs, significant water stress and also water scarcity being experienced in different parts of the world.

Who publishes the UNs world water development report?

  • The United Nations World Water Development Report (WWDR) is published by UNESCO, on behalf of UN-Water and its production is coordinated by the UNESCO World Water Assessment Program (WWAP).

What is the level of water stress in India?

  • The Global Drought Risk and Water Stress map (2019): It shows that major parts of India, particularly west, central and parts of peninsular India are highly water stressed and experience water scarcity.
  • Composite Water Management Index (2018): Released by Niti Aayog indicates that more than 600 million people are facing acute water stress.
  • India is the world’s largest extractor of groundwater: Accounting for 25 per cent of the total. 70 percent of our water sources are contaminated and our major rivers are dying because of pollution.

water stressWhy is Rural to Urban transfer of water becoming an issue in India?

  • Rising urban population: According to Census 2011, the urban population in India accounted for 34% of total population. It is estimated that the urban population component in India will cross the 40% mark by 2030 and the 50% mark by 2050 according to World Urbanization Prospects, 2018.
  • Water use in the urban areas: Water use in the urban sector has increased as more and more people shift to urban areas. Per capita use of water in these centers rises, which will continue to grow with improved standards of living.
  • Shifting of water source in Urban areas: As the city grows and water management infrastructures develop, dependence shifts to surface water from groundwater. For example: In Ahmedabad, more than 80% of water supply used to be met from groundwater sources till the mid-1980s. Due to such overexploitation of groundwater the depth to groundwater level reached 67 meters in confined aquifers. The city now depends on the Narmada canal for the bulk of its water supply.
  • Dependence of urban areas on rural areas for water source and rural-urban disputes over water: Cities largely depend on rural areas for raw water supply, which has the potential to ignite the rural-urban dispute. For example: Nagpur and Chennai face the problem of rural-urban water disputes.

 

water stressReasons for disputes

  • Diversion of resource: Water is transported to urban areas at the expense of rural areas. Due to the high population in urban areas the water requirement for daily use is very high.
  • High demand of water for industrial purposes: In urban areas the water is heavily used in industries creating water stress.
  • High Agriculture dependence: In the rural areas water is used mainly for irrigation purposes and due to heavy dependence on agriculture the water is very essential in rural areas.
  • Water pollution: In cities, most of this water is in the form of grey water with little recovery or reuse, eventually contributing to water pollution.
  • Bad governance: Politicization of water for vote bank and skewed distribution of water particular regions For example: Andhra and Telangana.

water stress Climate change exacerbate the rural-urban disputes 

  • Affecting rainfall pattern: Climate change affects the amount of rainfall in the region which is the prime source of both surface water and groundwater.
  • Increase rate of evaporation over surface water: because of high temperature the surface waters of lakes, rivers, canals etc. face high evaporation water loss.
  • Melting of glaciers: glaciers are the sources for perennial rivers of India. Due to global warming, glaciers are melting and hence affecting the perennial nature of rivers.
  • Frequent droughts: It affects the groundwater recharge process and drying of surface waters which creates shortage of water. It exacerbate the rural-urban conflict.

Prelims level: mullaperiyar dam

Mains level: dam safety bill ,DRIP.

dam safety billContext

  • Integrated risk assessment of dam safety required to prevent human-made disasters: Experts

Why in news?

  • The recent floods in the Mahanadi basin in Odisha have brought to the fore, the faulty management of dam safety, which were built to mitigate floods and not be the cause of them.

What is a dam?

  • A dam is a barrier that stops the flow of water and results in the creation of a reservoir. Dams are mainly built in order to produce electricity by using water. This form of electricity is known as hydroelectricity.
  • Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.

Key facts

India has 5,745 large dams according to the National Register of Large Dams, 2019, prepared by the Central Water Commission. Some 5,334 of them are operational and the remaining 411 are under construction.

What is the Dam Safety Act, 2021?

  • The Act comprehensively postulates for surveillance, inspection, operation and maintenance of dams to prevent disasters.

Features

  • National Committee on Dam Safety (NCDS): It will be constituted and will be chaired by the chairperson, Central Water Commission. Its’ functions will include formulating policies and regulations regarding dam safety standards and prevention of dam failures, analyzing the causes of major dam failures, and suggesting changes in dam safety practices.
  • National Dam Safety Authority (NDSA): It will be headed by an officer, not below the rank of an Additional Secretary, to be appointed by the central government. The main task of this authority includes implementing the policies formulated by the NCD, resolving issues between State Dam Safety Organisations (SDSOs), or between an SDSO and any dam owner in that state, specifying regulations for inspection and investigation of dams.
  • State Dam Safety Organisation (SDSO): Its functions will be to keep perpetual surveillance, inspection, monitoring the operation and maintenance of dams, keeping a database of all dams, and recommending safety measures to owners of dams.
  • Dam Safety Unit: The owners of the specified dams are required to provide a dam safety unit in each dam. This unit will inspect the dams before and after the monsoon session, and during and after any calamity or sign of distress.
  • Emergency Action Plan: Dam owners will be required to prepare an emergency action plan, and carry out risk assessment studies for each dam at specified regular intervals.
  • Certain offences: The act provides for two types of offences – obstructing a person in the discharge of his functions, and refusing to comply with directions issued under the proposed law.

dam safetyDam rehabilitation and improvement programme DRIP

  • Government of India, with financial assistance from the World Bank initiated Dam Rehabilitation and Improvement Project (DRIP) in April 2012 with an objective to improve the safety and operational performance of selected existing dams along with dam safety institutional strengthening with system wide management approach. It was a State Sector Scheme with Central component.

Do you know?

Kali Bein and its cultural significance

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Kali Bein

Mains level: River water management issues

Punjab CM has been admitted to hospital, days after he had drunk a glass of water directly from the Kali Bein, a holy rivulet in Sultanpur Lodhi.

What is the Kali Bein?

  • The 165-km rivulet starts from Hoshiarpur, runs across four districts and meets the confluence of the rivers Beas and Sutlej in Kapurthala.
  • Along its banks are around 80 villages and half a dozen small and big towns.
  • Waste water from there as well as industrial waste used to flow into the rivulet via a drain, turning its waters black, hence the name Kali Bein (black rivulet).
  • Dense grass and weeds grew on the water until a cleaning project started.

Why did Punjab CM drink water from it?

  • The occasion was the 22nd anniversary of the cleaning project, which had started on July 16, 2000.
  • The project has been slow for years after having made remarkable progress in the initial years.
  • Nevertheless, when Mann drank water from it directly, it was a much cleaner Kali Bein than it was before 2000.

Cultural significance

  • The Kali Bein is of great significance to Sikh religion and history, because the first Guru, Nanak Dev, is said to have got enlightenment here.
  • When Guru Nanak Dev was staying at Sultanpur Lodhi with his sister Bebe Nanki, he would bathe in the Kali Bein.
  • He is said to have disappeared into the waters one day, before emerging on the third day.
  • The first thing he recited was the “Mool Mantra” of the Sikh religion.

How did the cleaning project start?

  • It was started by environmentalist Baba Balbir Singh Seechewal with a handful of followers, without government help.
  • They removed weeds, treated the water and spread awareness among residents.
  • Six years of hard work paid off when then President A P J Abdul Kalam visited the site in 2006 and praised them for their effort.
  • The then government in Punjab then announced that it would take up the project to stop the discharge of untreated water into the rivulet.

What is its national significance?

  • At one stage, the project had become a role model for river cleaning missions.
  • The ‘Kali Bein Model’ was cited as the blueprint for the National Mission for Clean Ganga.
  • Uma Bharti, then Union Minister for Water Resources, River Project and Ganga Rejuvenation, visited the Kali Bein in 2015, and called it a Guru Sthan for the Ganga project.

Detecting Microplastics in Human Blood

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Microplastics

Mains level: Microplastics Contamination

A study by researchers from The Netherlands has found Microplastics in blood samples. About half of these were PET (polyethylene tertraphthalate) plastics, which is used to make food grade bottles.

What are Microplastics?

  • Microplastics are tiny bits of various types of plastic found in the environment.
  • The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
  • There is no universal agreement on the size of microplastics. It defines microplastic as less than 5mm in length.
  • However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the blood stream.
  • Hence they agreed on an upper limit on the size of the particles as 0.0007 millimetre.

What were the plastics that the study looked for in the blood samples?

  • The study looked at the most commonly used plastic polymers.
  • These were polyethylene tetraphthalate (PET), polyethylene (used in making plastic carry bags), polymers of styrene (used in food packaging), poly (methyl methylacrylate) and poly propylene.
  • They found a presence of the first four types.

Significance of the study

  • Making a human health risk assessment in relation to plastic particles is not easy, perhaps not even possible, due to the lack of data on exposure of people to plastics.
  • In this sense, it is important to have studies like this one.
  • The authors of the paper also remark that validated methods to detect the tiny (trace) amounts of extremely small-sized (less than 10 micrometre) plastic particles are lacking.
  • Hence this study, which builds up a methods to check the same, is important.

Health hazard of microplastics

  • It is not yet clear if these microplastics can cross over from the blood stream to deposit in organs and cause diseases.
  • The report point out that the human placenta has shown to be permeable to tiny particles of polystyrene ( 50, 80 and 24 nanometre beads).
  • Experiments on rats where its lungs were exposed to polystryrene spheres (20 nanometre) led to translocation of the nanoparticles to the placental and foetal tissue.
  • Oral administration of microplastics in rats led to accumulation of these in the liver, kidney and gut.
  • Further studies have to be carried out to really assess the impact of plastics on humans.

Water management needs a hydro-social approach

| Governance | Mains Paper 2: Governance, Transparency & Accountability, Citizens Charters,Government Scheme/Policies
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Global Environmental Change (GEC) programme

Mains level: Paper 2- Water management

Context

The Global Water System Project, which was launched in 2003 as a joint initiative of the Earth System Science Partnership (ESSP) and Global Environmental Change (GEC) programme, epitomises global concern about the human-induced transformation of fresh water and its impact on the earth system and society.

Valuation of water

  • It is globally estimated that the gap between demand for and supply of fresh water may reach up to 40% by 2030 if present practices continue.
  • SDG 6: The formation of the 2030 Water Resource Group in 2008, at the instance of the World Economic Forum, and the World Bank’s promotion of the group’s activity since 2018, is in recognition of this problem and to help achieve the Sustainable Development Goal (SDG) on water availability and sanitation for all by 2030 (SDG 6).
  • The latest UN World Water Development Report, 2021, titled ‘Valuing Water’, has laid stress on the proper valuation of water by considering five interrelated perspectives: water sources; water infrastructure; water services; water as an input to production and socio-economic development, and socio-cultural values of water.

Need for hydro-social cycle approach

  • Designing a comprehensive mix of divergent views about water along with ecological and environmental issues held by stakeholder groups is necessary.
  • In this context, a hydro-social cycle approach provides an appropriate framework.
  • It repositions the natural hydrological cycle in a human-nature interactive structure and considers water and society as part of a historical and relational-dialectical process.
  • The anthropogenic factors directly influencing a freshwater system are the engineering of river channels, irrigation and other consumptive use of water, widespread land use/land cover change, change in an aquatic habitat, and point and non-point source pollution affecting water quality.

The intra- and inter-basin transfer (IBT) of water

  • IBT is a major hydrological intervention to rectify the imbalance in water availability due to naturally prevailing unequal distribution of water resources within a given territory.
  • There are several IBT initiatives across the world.
  • The National River Linking Project of India is one of those under construction.
  • Based on a multi-country case study analysis, the World Wildlife Fund/World Wide Fund for Nature (2009) has suggested a cautious approach and the necessity to adhere to sustainability principles set out by the World Commission on Dams while taking up IBT projects.

Issues with assumptions, use and management of freshwater resources in India

1] Contestation on concept of the surplus and deficit basin

  • The basic premise of IBT is to export water from the surplus basin to a deficit basin.
  • However, there is contestation on the concept of the surplus and deficit basin itself as the exercise is substantially hydrological.
  • Besides this, rainfall in many surplus basins has been reported as declining.
  • The status of the surplus basin may alter if these issues are considered.

2] Low capacity utilisation

  • There is concern about the present capacity utilisation of water resources created in the country.
  • By 2016, India created an irrigation potential for 112 million hectares, but the gross irrigated area was 93 million hectares.
  • There is a 19% gap, which is more in the case of canal irrigation.
  • In 1950-51, canal irrigation used to contribute 40% of net irrigated area, but by 2014-15, the net irrigated area under canal irrigation came down to less than 24%.
  • Groundwater irrigation now covers 62.8% of net irrigated area.
  • Low efficiency of irrigation projects: The average water use efficiency of irrigation projects in India is only 38% against 50%-60% in the case of developed countries.
  • More water consumption for crops: Even at the crop level we consume more water than the global average.
  • Rice and wheat, the two principal crops accounting for more than 75% of agricultural production use 2,850 m 3/tonnes and 1,654 m 3/tonnes of water, respectively, against the global average of 2,291m 3/tonnes and 1,334m 3/ tonnes in the same order.
  • The agriculture sector uses a little over 90% of total water use in India.
  • And in industrial plants, consumption is 2 times to 3.5 times higher per unit of production of similar plants in other countries.
  • Similarly, the domestic sector experiences a 30% to 40% loss of water due to leakage.

3] Low use of greywater

  • Grey water is hardly used in our country.
  • It is estimated that 55% to 75% of domestic water use turns into greywater depending on its nature of use, people’s habits, climatic conditions, etc.
  • At present, the average water consumption in the domestic sector in urban areas is 135 litres to 196 litres a head a day.
  • If grey water production in the rural areas is considered it will be a huge amount.
  • The discharge of untreated grey water and industrial effluents into freshwater bodies is cause for concern.
  • The situation will be further complicated if groundwater is affected.

4] Other issues

  • Apart from the inefficient use of water in all sectors, there is also a reduction in natural storage capacity and deterioration in catchment efficiency.

Way forward

  • The issues are source sustainability, renovation and maintenance of traditional water harvesting structures, grey water management infrastructure, groundwater recharge, increasing water use efficiency, and reuse of water.
  • The axiom that today’s water system is co-evolving and the challenges are mainly management and governance has been globally well accepted.
  • It is important to include less predictable variables, revise binary ways of thinking of ‘either or’, and involve non-state actors in decision-making processes.

Conclusion

A hybrid water management system is necessary, where along with professionals and policy makers the individual, a community and society have definite roles in the value chain. The challenge is not to be techno-centric but anthropogenic.

Water Management – Institutional Reforms, Conservation Efforts, etc.

In news: Bhakra Beas Management Board (BBMB)

| Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Bhakra Nangal Dam

Mains level: River water management issues

Political parties in Punjab are up in arms over the Centre’s decision to amend the rules regarding appointments to two key positions on the Bhakra Beas Management Board (BBMB).

What is BBMB?

(a) Origin

  • The genesis of BBMB lies in the Indus Water Treaty signed between India and Pakistan in 1960.
  • Under this, waters of three eastern rivers— Ravi, Beas and Sutlej — were allotted to India for exclusive use while Indus, Chenab and Jhelum rivers were allocated to Pakistan.
  • In India, a master plan was drawn to harness the potential of these rivers for providing assured irrigation, power generation and flood control.
  • Bhakra and Beas projects form a major part of this plan and were established as a joint venture of the then undivided Punjab and Rajasthan.

(b) Establishment

  • Following the reorganization of Punjab on November 1, 1966, and the creation of the state of Haryana, the BBMB was constituted under Section 79 of the Punjab Reorganisation Act, 1966.
  • The administration, maintenance and operation of Bhakra Nangal Dam project was handed over to Bhakra Management on October 1, 1967.
  • On May 15, 1976, when the Beas Projects Works were completed and handed over, the Bhakra Management Board was renamed as Bhakra Beas Management Board (BBMB).
  • Since then, BBMB regulates supply of water and power to Punjab, Haryana, Rajasthan, Himachal Pradesh, Delhi and Chandigarh.

What is the constitution of the BBMB management?

  • The BBMB management includes a chairperson and two whole time members who are from the partner states of Punjab and Haryana.
  • They are designated as Member (Power) and Member (Irrigation) from Punjab and Haryana, respectively.
  • There is representation from each member state including Rajasthan and Himachal Pradesh as nominated by the respective state governments.
  • The total strength of BBMB is about 12,000 employees and out of these 696 are Group A officers and are posted from the partner states.

What changes have been made to the BBMB rules?

  • The GoI issued a notification on February 23, 2022 to amend the BBMB Rules 1974, thereby changing the criteria for the selection of whole-time members of the Board.
  • New rules specify technical qualifications for the appointments and pave for the appointment of the members from across India and NOT ONLY from Punjab and Haryana.

What has been the objection to the new rules?

  • The opposition to the new rules has come from within the engineers’ fraternity, farmers as well as the political parties of Punjab.
  • It is being labeled as an attack on the federal structure of the country.
  • The engineers have pointed out that hardly any engineer would qualify for appointment as per the new specifications.

 

Back2Basics: Indus Waters Treaty, 1960

  •  The Indus Waters Treaty is a water-distribution treaty between India and Pakistan, brokered by the World Bank signed in Karachi in 1960.
  • According to this agreement, control over the water flowing in three “eastern” rivers of India — the Beas, the Ravi and the Sutlej was given to India.
  • The control over the water flowing in three “western” rivers of India — the Indus, the Chenab and the Jhelum was given to Pakistan.
  • The treaty allowed India to use western rivers water for limited irrigation use and unrestricted use for power generation, domestic, industrial and non-consumptive uses such as navigation, floating of property, fish culture, etc. while laying down precise regulations for India to build projects.
  • India has also been given the right to generate hydroelectricity through the run of the river (RoR) projects on the Western Rivers which, subject to specific criteria for design and operation is unrestricted.

Kerala plans to replace Mullaperiyar Dam

Prelims Only | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Mullaperiyar Dam

Mains level: Not Much

Kerala plans to build a new dam to replace the 126-year-old Mullaperiyar dam in the Idukki district.

Mullaperiyar Dam

  • It is a masonry gravity dam on the Periyar River in Kerala.
  • It is located on the Cardamom Hills of the Western Ghats in Thekkady, Idukki District.
  • It was constructed between 1887 and 1895 by John Pennycuick and also reached in an agreement to divert water eastwards to the Madras Presidency area.
  • It has a height of 53.6 m (176 ft) from the foundation, and a length of 365.7 m (1,200 ft).

Operational issue

  • The dam is located in Kerala but is operated and maintained by Tamil Nadu.
  • The catchment area of the Mullaperiyar Dam itself lies entirely in Kerala and thus not an inter-State river.
  • In November 2014, the water level hit 142 feet for first time in 35 years.
  • The reservoir again hit the maximum limit of 142 feet in August 2018, following incessant rains in the state of Kerala.
  • Indeed, the tendency to store water to almost the full level of reservoirs is becoming a norm among water managers across States.

The dispute: Control and safety of the dam

  • Supreme court judgment came in February 2006, has allowed Tamil Nadu to raise the level of the dam to 152 ft (46 m) after strengthening it.
  • Responding to it, the Mullaperiyar dam was declared an ‘endangered’ scheduled dam by the Kerala Government under the disputed Kerala Irrigation and Water Conservation (Amendment) Act, 2006.
  • For Tamil Nadu, the Mullaperiyar dam and the diverted Periyar waters act as a lifeline for Theni, Madurai, Sivaganga, Dindigul and Ramnad districts.
  • Tamil Nadu has insisted on exercising the unfettered colonial rights to control the dam and its waters, based on the 1886 lease agreement.

Rule of Curve issue

  • A rule curve or rule level specifies the storage or empty space to be maintained in a reservoir during different times of the year.
  • It decides the fluctuating storage levels in a reservoir.
  • The gate opening schedule of a dam is based on the rule curve. It is part of the “core safety” mechanism in a dam.
  • The TN government often blames Kerala for delaying the finalization of the rule curve.

Radioactive Pollution in Water

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Raidioactivity

Mains level: Water Pollution

Radioactive pollution of water is newly emerging but is of grave concern for water pollution and human health.

Quick recap: Radioactivity

  • Radioactivity is the phenomenon of spontaneous emission of particles or waves from the unstable nuclei of some elements.
  • There are three types of radioactive emissions: Alpha, Beta and Gamma.
  • Alpha particles are positively charged He atoms, beta particles are negatively charged electrons and gamma rays are neutral electromagnetic radiations.
  • Radioactive elements are naturally found in the earth’s crust.

Radioactive contamination of Water

  • Natural: Percolation of naturally occurring radioactive materials (NORM) from the soil sediments to the aquifer causes groundwater contamination.
  • Man-made: Anthropogenic sources of such pollution include- nuclear weapon investigation, nuclear calamities, nuclear powerhouses and dumping of radioactive waste.

Various contaminant elements

  • Uranium, thorium and actinium are three NORM series that contaminate water resources.
  • A number of radionuclides are found in surface and subsurface waters, among which 3H, 14C, 40K, 210Pb, 210Po, 222Rn, 226Ra, 228Ra, 232Th and 234,235,238U are common.
  • Strontium-90, Caesium-137, etc are also formed by nuclear reactors, along with numerous unnecessary radioisotopes wastes.
  • 40K and 7Be are the most commonly found radioactive elements in the sludge generated in sewage treatment plants.
  • Nuclear reactors produce radioisotopes (Cobalt-60, Iridium-192, etc) that hand out as sources of gamma radiation in radiotherapy and numerous industrial appliances.

Oceanic sources

  • Oceans and seas are the natural repositories of naturally occurring uranium. It is found in the form of uranyl carbonate ion.
  • A significant concentration of uranium is supposed to be found in the greater salinity of the marine water.
  • 40K (Radioactive Potassium) is also found in considerable concentration in the marine environment.

Measuring radioactive pollution

  • Radioactivity is measured in Becquerel (SI unit) or in Curie.
  • Energy absorbed per unit mass is measured by Gray, while the unit Sievert measures the quantity of radiation absorbed by human tissues.
  • A small amount of radiation is found in all types of water but the extended amount of radiation is harmful to human health.
  • Radioactivity in drinking water can be determined by a gross alpha test.

Hazards of such pollution

  • Radioactive elements have an effect on the environment and can cause a risk to human healthiness if inhaled, injected or exposed.
  • Human tissues absorb radiation through polluted water and foodstuff, which can cause serious health risks.
  • High doses of radiation can cause acute radiation syndrome or cutaneous radiation injury.
  • Exposure to radiation causes various disorders in human physiology, including cancer, leukaemia, genetic mutations, osteonecrosis, cataracts and chromosomal disruption.

Froth formation in Yamuna

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Froth Formation

Mains level: Not Much

The visuals of devotees taking a dip in the froth-filled waters of the Yamuna River sent chills down the spine of the residents of Delhi.

What is Froth Formation?

  • This is a phenomenon that takes place on many lakes and streams.
  • Foam bubbles are produced when organic matter decomposes.
  • These foam-producing molecules have one end that repels water and another that attracts water and they work to reduce the surface tension on the surface of the water.
  • These foam bubbles are lighter than water, so they float on the surface as a thin film that gradually accumulates.

What causes the froth?

  • The presence of phosphates and surfactants in untreated sewage from Delhi, Haryana and Uttar Pradesh is a major reason behind frothing.
  • While these two components comprise of 1 per cent, the remaining 99 percent is air and water.

What are the sources of pollution that cause foam formation?

  • Untreated sewage may contain soap-detergent particles.
  • The other sources are industrial effluents, organic matter from decomposing vegetation, and the presence of filamentous bacteria.
  • The pollution from the sugar and paper industries in Uttar Pradesh also causes pollution in the Yamuna.

What are its health hazards?

  • Short-term exposure can lead to skin irritation and allergies.
  • If ingested, these chemicals may cause gastrointestinal problems and diseases like typhoid.
  • Long-term exposure to heavy metals in industrial pollutants can cause neurological issues and hormonal imbalances.

What India’s new water policy seeks to deliver

op-ed snap | Governance | Mains Paper 2: Executive & Judiciary,Governance, Transparency & Accountability, Citizens Charters
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Not much

Mains level: Paper 2- National Water Policy

Context

Over a period of one year, the committee set up to draft the new National Water Policy (NWP) received 124 submissions by state and central governments, academics and practitioners. The NWP is based on the striking consensus that emerged through these wide-ranging deliberations.

Major suggestion in NWP

Demand-side: Diversification of public procurement operations

  • Irrigation consumes 80-90 per cent of India’s water, most of which is used by rice, wheat and sugarcane.
  • Thus, crop diversification is the single most important step in resolving India’s water crisis.
  • The policy suggests diversifying public procurement operations to include nutri-cereals, pulses and oilseeds.
  • This would incentivise farmers to diversify their cropping patterns, resulting in huge savings of water.

2) Reduce-Recycle-Reuse

  • Reduce-Recycle-Reuse has been proposed as the basic mantra of integrated urban water supply and wastewater management, with treatment of sewage and eco-restoration of urban river stretches, as far as possible through decentralised wastewater management.
  • All non-potable use, such as flushing, fire protection, vehicle washing must mandatorily shift to treated wastewater.

3) Supply-side measure: Using technology to utilised stored water in dams

  • Within supply-side options, the NWP points to trillions of litres stored in big dams, which are still not reaching farmers.
  • NWP suggests how the irrigated areas could be greatly expanded at very low cost by deploying pressurised closed conveyance pipelines, combined with Supervisory Control and Data Acquisition (SCADA) systems and pressurised micro-irrigation.

4) Supply of water through “nature-based solutions”

  • The NWP places major emphasis on supply of water through “nature-based solutions” such as the rejuvenation of catchment areas, to be incentivised through compensation for ecosystem services.
  • Specially curated “blue-green infrastructure” such as rain gardens and bio-swales, restored rivers with wet meadows, wetlands constructed for bio-remediation, urban parks, permeable pavements, green roofs etc are proposed for urban areas.

5) Sustainable and equitable management of groundwater

  • Information on aquifer boundaries, water storage capacities and flows provided in a user-friendly manner to stakeholders, designated as custodians of their aquifers, would enable them to develop protocols for effective management of groundwater.

6) Rights of Rivers

  • The NWP accords river protection and revitalisation prior and primary importance.
  • Steps to restore river flows include: Re-vegetation of catchments, regulation of groundwater extraction, river-bed pumping and mining of sand and boulders.
  • The NWP outlines a process to draft a Rights of Rivers Act, including their right to flow, to meander and to meet the sea.

7) Emphasis on water quality

  • The new NWP considers water quality as the most serious un-addressed issue in India today.
  • It proposes that every water ministry, at the Centre and states, include a water quality department.
  • The policy advocates adoption of state-of-the-art, low-cost, low-energy, eco-sensitive technologies for sewage treatment.
  • Widespread use of reverse osmosis has led to huge water wastage and adverse impact on water quality.
  • The policy wants RO units to be discouraged if the total dissolved solids count in water is less than 500mg/L.
  • It suggests a task force on emerging water contaminants to better understand and tackle the threats they are likely to pose.

8) Reforming governance of water

  • The policy makes radical suggestions for reforming governance of water, which suffers from three kinds issues: That between irrigation and drinking water, surface and groundwater, as also water and wastewater.
  • Government departments, working in silos, have generally dealt with just one side of these binaries.
  • Dealing with drinking water and irrigation in silos has meant that aquifers providing assured sources of drinking water dry up because the same aquifers are used for irrigation, which consumes much more water.
  • And when water and wastewater are separated in planning, the result is a fall in water quality.

9) Creation of National Water Commission

  • The NWP also suggests the creation of a unified multi-disciplinary, multi-stakeholder National Water Commission (NWC), which would become an exemplar for states to follow.
  • Governments should build enduring partnerships with primary stakeholders of water, who must become an integral part of the NWC and its counterparts in the states.

Conclusion

The new National Water Policy calls for multi-disciplinary, multi-stakeholder approach to water management.

Who was Hermann Bacher?

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Hermann Bacher

Mains level: Watershed development in India

Hermann Bacher, popularly known as the ‘father of community-led watershed development in India’, passed away at the ripe old age of 97 years in Switzerland September 14, 2021.

Hermann Bacher

  • Born in 1924, Bacher, came to India in 1948 at the young age of 24 years.
  • He was to spend the next 60 years of his life here, most of it in Maharashtra.
  • Struck by the poverty he saw in rural Maharashtra, he dedicated his life to the upliftment of the poor, the landless and rural women.
  • Bacher was given Germany’s highest civilian award, the Federal Cross of the Order of Merit in 1994, in recognition of his outstanding efforts.
  • In 2017, the United Nations Convention to Combat Desertifiucation (UNCCD) awarded WOTR the prestigious ‘Land for Life Award 2017’.
  • He is widely regarded and respected as a true ‘man of God’ for whom selfless service of the poor was worship at its most sublime. He is fondly remembered as ‘Bacher Baba’.

Notable works

  • The 1972 droughts in Maharashtra led him to re-calibrate his developmental approach.
  • This meant that in rain-dependent rural Maharashtra, a shift had to be made from ‘resource exploitation’ to sustainable resource use, or ‘resource mobilisation’, as he described it.
  • He helped thousands of landless labourers’ secure title to land under the Land Reforms Act, 1957, beginning in 1965.
  • He also organised lakhs of farmers to develop their farms and increase their agricultural productivity by helping them access irrigation, improved and hybrid seeds etc.

Pioneering water harvest

  • Since rain fell in the watersheds and landscapes villagers lived in, the only way to harvest and conserve rainwater wherever it fell was to undertake watershed development measures.
  • The idea was that “running water must be made to walk; walking water made to stop and sink underground”.
  • This meant, planting trees and grasses, conserving forests, undertaking soil and water conservation works such as digging contour trenches, raising farm bunds, etc.
  • It also meant building water harvesting structures on the streams (check dams, earthen bunds, etc) in a systematic manner across the entire landscape of the village, beginning from the top.

Establishing the IGWDP

  • Through his work, was born the idea which later became the large-scale Indo-German Watershed Development Program (IGWDP) that he conceived and launched in Maharashtra in 1989.
  • This was in collaboration with and the support of the Governments of India, Maharashtra and Germany, NABARD and the non-profit sector.
  • Its unique and ground-breaking feature was that it put the villagers in the driver’s seat — the community would plan the programme, implement it and maintain the watershed assets.
  • Funds, substantial amounts, would be given directly to them and they would have to manage and account

Wastewater Treatment in India

DOMR | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Important facts mentioned

Mains level: Wastewater treatment in India

Sewage treatment plants (STPs) in India are able to treat a little more than a third of the sewage generated per day, according to the latest report of the Central Pollution Control Board (CPCB).

What is Wastewater?

Wastewater is used water from any combination of domestic, industrial, commercial or agricultural activities, surface runoff/ stormwater, and any sewer inflow or sewer infiltration.

In everyday usage, wastewater is commonly a synonym for:

  • Sewage also called domestic wastewater or municipal wastewater which is wastewater that is produced by a community of people.
  • Industrial wastewater, water-borne waste generated from a variety of industrial processes, such as manufacturing operations, mineral extraction, power generation, or water and wastewater treatment.
  • Cooling water, released with potential thermal pollution after use to condense steam or reduce machinery temperatures by conduction or evaporation
  • Leachate, precipitation containing pollutants dissolved while percolating through ores, raw materials, products, or solid waste
  • Return flow, carrying suspended soil, pesticide residues, or dissolved minerals and nutrients from irrigated cropland
  • Surface runoff, the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil.
  • Urban runoff, including water used for outdoor cleaning activity and landscape irrigation in densely populated areas created by urbanization
  • Agricultural wastewater, generated from confined animal operations

Wastewater in India

  • India generated 72,368 MLD (million litres per day) whereas the installed capacity of STPs was 31,841 MLD (43.9 per cent), according to the report.

Treatment facilities available

  • Of this installed capacity, developed and operationalized capacity was 26,869 MLD (84 per cent).
  • Of the total operationalised capacity, 20,235 MLD (75 per cent) was the actual utilised capacity.
  • In other words, out of total 72,368 MLD sewage generated every day, only 20,235 MLD is treated.

Skewed distribution

  • Five states and Union Territories (UT) — Maharashtra, Gujarat, Uttar Pradesh, Delhi and Karnataka — account for 60 per cent of the total installed treatment capacity of the country.
  • These, along with five other states and UTs — Madhya Pradesh, Haryana, Punjab, Tamil Nadu and Rajasthan — alone constitute 86 per cent of the total installed capacity.
  • Arunachal Pradesh, Andaman & Nicobar Islands, Lakshadweep, Manipur, Meghalaya and Nagaland have not installed sewage treatment plants.
  • There are states like Bihar which do have a small installed capacity of STPs. But on the operational front, they score a zero.
  • Chandigarh ranks first in terms of total sewage generated to what is actually treated. It generates 188 MLD of sewage and has an operational capacity to treat 271 MLD.

Major issue: Reuse of sewage

  • The reuse of treated sewage is an issue which hasn’t assumed much importance in the policy planning of many state governments.
  • Treated sewage water can be reused for horticulture, irrigation, washing activities (road, vehicles and trains), fire-fighting, industrial cooling, toilet flushing and gardening.
  • The proportion of the reuse of treated sewage is maximum in Haryana (80 per cent) followed by Puducherry (55 per cent), Delhi (50 per cent), Chandigarh (35 per cent), Tamil Nadu (25 per cent), Madhya Pradesh (20 per cent) and Andhra Pradesh (5 per cent).

Universal Declaration of the Rights of Rivers

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Rights of River

Mains level: River conservation

Activists have highlighted the plight of rivers as well as the support building up for according rights to them under the Universal Declaration of the Rights of Rivers.

What constitutes the Rights of Rivers?

  • Flow: If we look at a river as an ecosystem instead of cubic metres of water, then the ambit of rights gets broadened.
  • Flora and fauna: It includes aquatic flora and fauna, the biodiversity in its catchment areas, forests, its tributaries, groundwater, the rocks and soil in its bed and banks.
  • Human settlements: The rights of rivers in a sense would mean the ecological causes and conditions making up the natural habitat. Human settlements dependent is the prime factor.
  • Economy: Such rights should not put an end to fishing or other localized, subsistence-based human needs related to the river, but rather push for a healthy relationship respecting the river as an ecosystem.

Universal Declaration of the Rights of Rivers

  • The declaration is a civil society initiative to define the basic rights to which all rivers are entitled, according to a note by non-profit, International Rivers.
  • This trend of granting rights to nature, taking place across the world, signals the beginnings of a radical shift from an extractive mindset to one where conservation safeguards are being extended to nature.
  • The right to recognize rivers as living entities rather than mere human property started in 2008.
  • That year, Ecuador became the first country to constitutionally recognize the Rights of Nature.

Present campaigns

  • In the one year since the declaration, rights have been recognised or declared for the Boulder Creek watershed in the US, the Magpie River in Canada, the Alpayacu river in Ecuador and the Paraná river and its wetlands in Argentina.
  • Several campaigns calling for rights to be accorded to rivers have also incorporated the declaration.
  • These include campaigns for the Lempa river in El Salvador, Tavignanu river in France, Ethiope river in Nigeria, the Indus river in Pakistan and the Frome river in the UK.
  • In 2017, a treaty agreement between the Whanganui Iwi (a Māori tribe) and the New Zealand government recognized the Whanganui River as a legal person.

Recognition of such rights in India

  • In 2017, the Uttarakhand HC ruled that the Indian rivers Ganga and Yamuna, the Gangotri and Yamunotri glaciers, as well as other related natural elements are “legal persons” with all corresponding rights, duties, and liabilities of a living person.
  • Subsequently, in 2018, the same high court ruled that the entire animal kingdom has rights equivalent to that of a living person.

Challenges

  • Cultural practices: Activists and communities have been arguing for a need of cultural change that can bring about the ethic of care with regard to the rest of nature. Indigenous people have had such an ethic in their worldviews and ways of living.
  • Development paradigm: The most critical challenge is whether can rights be protected without changing the current development paradigm. Any paradigm shift also needs questioning of fundamental forms of injustices, including capitalism, statism, anthropocentrism, and patriarchy.
  • Cross-boundary issues: Rivers don’t necessarily follow human-made political boundaries. Indus, one of the longest that runs through China, Pakistan, and India, doesn’t flow as per political boundaries. Its contiguity demands a cross-boundary approach.
  • Cooperation deficit: There is still very limited understanding across the world on how a law on the rights of rivers can be implemented. What would be the best ways to ensure custodianship, restitution, compensation.

The federal government in the US has declared a water shortage for the Colorado river basin due to a historic drought.

Try this PYQ

Q. Consider the following pairs

River – Flows into

  1. Mekong — Andaman Sea
  2. Thames — Irish Sea
  3. Volga — Caspian Sea
  4. Zambezi — Indian Ocean

Which of the pairs given above is/are correctly matched?(CSP 2020)

(c) 3 and 4 only

(d) 1, 2 and 4 only

 

Post your answers here (you need to sign-in for that).

Colorado River

  • The Colorado River flows from the Rocky Mountains into the southwestern US and into Mexico.
  • The river is fed by snowmelt from the Rocky and Wasatch mountains and flows a distance of over 2,250 km (river Ganga flows through a distance of roughly 2,500 km) across seven states and into Mexico.
  • The Colorado River Basin is divided into the Upper (Wyoming, Colorado, New Mexico, Utah and northern Arizona) and Lower Basins (parts of Nevada, Arizona, California, southwestern Utah and western New Mexico).
  • In the Lower Basin, the Hoover Dam controls floods and regulates water delivery and storage.
  • Apart from the Hoover dam, there is the Davis Dam, Parker Dam and the Imperial Dam that regulate the release of water from the Hoover Dam.

Major lakes in its basin

  • Lake Mead is the largest reservoir in the US in terms of volume and was formed in the 1930s by the Hoover Dam in Southern Nevada.
  • Its main source of water is obtained from the Rocky Mountain snowmelt and runoff.
  • The other is Lake Powell, the reservoir created by the Glen Canyon Dam in Arizona.

Reasons for shortage

  • Since the year 2000, this river basin has been experiencing a prolonged drought.
  • This persistent drought has led to a lowering down of the water levels in the basin’s reservoirs to meet the demand over the years.
  • But even with great water storing capacity, over the years the demand for water from the basin has increased whereas supply is restricted.

Microplastics Pollution in Ganga

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Microplastic pollution

Mains level: Water Pollution

 

The Ganga is heavily polluted with microplastics at Varanasi, Haridwar, and Kanpur, Delhi-based non-profit Toxics Link claimed.

What are Microplastics?

  • Microplastics are plastics that are less than 5 mm in size but are a major source of marine pollution.
  • Untreated sewage from many cities along the river’s course, industrial waste, and religious offerings wrapped in non-degradable plastics pile pollutants into the river as it flows through several densely populated cities.
  • The plastic products and waste materials released or dumped in the river break down and are eventually broken down into microparticles.
  • The rivers finally transport significantly large quantities downstream into the ocean, which is the ultimate sink of all plastics being used by humans.

Microplastics in Ganga

  • They are non-degradable plastics that often entered the Ganga through industrial waste or packaging of religious offerings, its research found.
  • The density of population in the three cities also added to the problem because a large chunk of pollutants got directly discharged into the river by people living on the banks.
  • Among the three cities, the Toxics Link’s study found that sites at Varanasi showed the maximum load of microplastics in the water of the Ganga, as compared to the other two cities.
  • This might be due to cumulative downstream pollution as well as industrial and human activities.

On a global high

  • The researchers tried to compare the microplastics concentration in Ganga water with similar studies on other rivers across the globe.
  • It included the Rhine in Europe, the Patapsco, Magothy, Rhode in North America, and the Elqui, Maipo, Biobio, and Maule in South America.
  • They found the Ganga microplastics pollution was much higher.
  • This was in spite of a higher per capita consumption of plastic in the European countries, North and South America, as compared to India.

How does it impact people?

  • The Ganga is a source of water for not just drinking and bathing purposes but also for irrigation to a large extent.
  • Microplastics in river water, if ingested in humans or other organisms, can cause toxicity through various means.
  • Not only are these microplastics toxic themselves, they also have a tendency to absorb various toxins present in water, including harmful chemicals.
  • Although some of the effects of microplastics on public health are understood, a lot still needs to be done.

Answer this PYQ in the comment box:

Q. Why is there a great concern about the ‘microbeads’ that are released into the environment? (CSP 2019)

(a) They are considered harmful to marine ecosystems.

(b) They are considered to cause skin cancer in children.

(c) They are small enough to be absorbed by crop plants in irrigated fields.

(d) They are often found to be used as food adulterants.

Rooftop rainwater harvesting for India’s water stress

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Not much

Mains level: Rooftop Rain Water Harvesting

India’s rapid urban growth is expected to stress its already crumbling base of public service arrangements — especially its management of water and sanitation services, whose safe and reliable availability proved to be the first line of defence against this covid pandemic.

Q.Discuss how Rooftop rainwater harvesting can ease India’s water woes? (150W)

Rooftop Rain Water Harvesting

  • It is the technique through which rainwater is captured from the roof catchments and stored in reservoirs.
  • Harvested rainwater can be stored in sub-surface groundwater reservoirs by adopting artificial recharge techniques to meet the household needs through storage in tanks.
  • Capturing and storing rainwater for use is particularly important in dryland, hilly, urban and coastal areas.
  • It holds the potential to support the country’s preparedness against the incipient challenges of changing climate.

Water stress in India

  • An appalling confusion grips our policy makers and planners.
  • While the supply-demand gap is expected to widen by 50 per cent by 2030, many are still left without access to safe and sustainable water and sanitation services.
  • At least five Indian cities are already reported to have joined the list of world’s 20 largest water-stressed cities.

If we look at the present portfolio of water resources management for other cities, it will not be wrong to claim that many more will soon become qualified for joining this infamous list.

Exploring the complex problems

  • Water availability in India remains at the mercy of erratic patterns of precipitation.
  • Concretization of urban landscapes, symbolic of modern town planning imaginaries as to what an exercise in urban development has led to floods worsening.
  • Illegal encroachment along stormwater drains and urban rivers also aggravates the situation, not least by opening up spaces of active political contestation and negotiations.

A paradigm shift needed

  • In India, management of water was bundled as part of the prerogative claims of post-independent public institutions with public participation programs designed later on to serve only a placatory function.
  • This has led to the systematic exclusion of the public’s opinions in informing the design and implementation protocols of large public schemes.
  • It took the form of multi-purpose dams, irrigation canals, public water distribution systems, etc.
  • Despite this, India has now become a ‘water-stressed country.

A newer approach

  • Rising national empathy for river rejuvenation, watershed conservation and active public participation has, on the other hand, already started scripting a new paradigm for India’s water management.
  • It prompts decision-makers to look for solutions in the collective efforts of the citizens in managing their issues locally.

Right from the vedic times

  • Our Vedic ancestors, in their appreciation of the timeless bounty of water, always offered timely obeisance to water’s eternal gifts to mankind.
  • Their reverence to water can be found in the hymns and prayers offered to Varuna and Indra — Vedic Gods associated with water to riveting architectural gems and literary delights, each underscoring the centrality of water in our cultural revelries.
  • It is time our policies are re-designed to reflect these values.

Empowering people

  • Rooftop rainwater structures are perfectly poised to engender a transformative wave of public engagement in water management.
  • Thus it can act as a corollary for making water management an exercise in nurturing democratic routines.
  • To ensure that the public enthusiastically purchases this concept, a country-wide behaviour change campaign can be launched along the lines of the Swachh Bharat Mission.
  • This can emphasize people’s ‘ability and ‘motivation’ to romantically welcome these structures in their private premises.
  • This should rather be a ‘do-it-yourself’ model of engagement.

The Sardar Sarovar Dam is providing irrigation water in summer for the first time in history.

Sardar Sarovar Dam

  • The Sardar Sarovar Narmada Dam is a terminal dam built on the Narmada river at Kevadia in Gujarat’s Narmada district.
  • Four Indian states, Gujarat, Madhya Pradesh, Maharashtra and Rajasthan, receive water and electricity supply from the dam.
  • The foundation stone of the project was laid out by Prime Minister Jawaharlal Nehru on 5 April 1961.
  • The project took form in 1979 as part of a development scheme funded by the World Bank through their International Bank for Reconstruction and Development, to increase irrigation and produce hydroelectricity
  • Called the ‘lifeline of Gujarat’, it usually has no water for irrigation during summers.

Q.Which one of the following pairs is not correctly matched?

 

Dam/Lake River

(a) Govind Sagar: Satluj

(b) Kolleru Lake: Krishna

(c) Ukai Reservoir: Tapi

(d) Wular Lake: Jhelum

A successful model of river water sharing

  • River Narmada is a classic case of Integrated River Basin Planning, Development, and Management, with water storage available in all major, medium, and minor dams on the main river and its tributaries.
  • Its water is shared amongst four party states – Gujarat, Rajasthan, Madhya Pradesh and Maharashtra — in the ratio stipulated by the 1979 award of the Narmada Water Dispute Tribunal.

How has it saved water for summers?

  • During the monsoon from July to October, the reservoir operation is well synchronized with the rain forecast in the catchment area.
  • The strategic operation of River Bed Power House (RPBH) ensures that minimum water flows downstream into the sea and maximum water is used during the dam overflow period, which is not calculated in the annual water share.
  • These measures help in maximizing the annual allocation of water share.
  • Similarly, in non-monsoon months, the measures for efficient use of the allocated share typically include minimizing the conventional and operational losses.
  • It includes: avoiding water wastage, restricting water-intensive perennial crops, adopting of Underground Pipelines (UGPL); proper maintenance and operation of canals on a rotational basis.

‘Sea Snot’ outbreak in Turkey

India MappingPrelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Sea Snot, Marmara Sea

Mains level: Algal bloom

There has been growing environmental concern in Turkey over the accumulation of ‘sea snot’, a slimy layer of grey or green sludge in the country’s seas, which can cause considerable damage to the marine ecosystem.

What is ‘Sea Snot’?

  • ‘Sea snot’ is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change.
  • A ‘sea snot’ outbreak was first recorded in the country in 2007. Back then, it was also spotted in the Aegean Sea near Greece.
  • But the current outbreak in the Sea of Marmara is by far the biggest in the country’s history.
  • The nutrient overload occurs when algae feast on warm weather caused by global warming. Water pollution adds to the problem.
  • Environmental experts have said that the overproduction of phytoplankton caused by climate change and the uncontrolled dumping of household and industrial waste into the seas has led to the present crisis.

Where has it been found?

  • Turkey’s Sea of Marmara, which connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’.
  • The sludge has also been spotted in the adjoining Black and Aegean seas.

How badly can the crisis affect the marine ecosystem?

  • The growth of the mucilage, which floats upon the surface of the sea like brown phlegm, is posing a severe threat to the marine ecosystem of the country.
  • Divers have said that it has caused mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges.
  • The mucilage is now covering the surface of the sea and has also spread to 80-100 feet below the surface.
  • If unchecked, this can collapse to the bottom and cover the sea floor, causing major damage to the marine ecosystem.
  • Over a period of time, it could end up poisoning all aquatic life, including fishes, crabs, oysters, mussels and sea stars.

The problem of ageing dams in India

| Enviro & Biodiversity | Mains Paper 3: Disaster Management
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Rate of siltation

Mains level: Paper 3- Ageing dams and challenges associated with it

Ageing dams threaten India’s water security, affect farmers’ income and increases the frequency of flooding. 

What is a dam?

  • A dam is a barrier that stops the flow of water and results in the creation of a reservoir. Dams are mainly built in order to produce electricity by using water. This form of electricity is known as hydroelectricity.
  • Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.

Types of Dams

There are many dams in India, and hence there is a need to know about them as there are questions based on the dams of India. The Bank Exams like IBPS or SBI contains questions from this section.

Based on the structure the types of dams are as mentioned below:

  1. Arch Dam: An arch dam is a concrete dam that is curved upstream in the plan. It is designed so that the hydrostatic pressure (force of the water against it) presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses.
  2. Gravity Dam: Dams constructed from concrete or stone masonry are Gravity dams. They are designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. These are designed in such a way that each section of the dam is stable and independent of other section.
  3. Arch-Gravity Dam: This dam has the characteristics of both an arch dam and a gravity dam. It is a dam that curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls. The inward compression of the dam by the water reduces the lateral (horizontal) force acting on the dam.
  4. Barrages: A barrage is a type of low-head, diversion dam which consists of a number of large gates that can be opened or closed to control the amount of water passing through. This allows the structure to regulate and stabilize river water elevation upstream for use in irrigation and other systems.
  5. Embankment Dams: An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core.
  6. Rock-Fills Dams: Rock-fill dams are embankments of compacted free-draining granular earth with an impervious zone. The earth utilized often contains a high percentage of large particles, hence the term “rock-fill”.
  7. Concrete-face rock-fill dams: A concrete-face rock-fill dam (CFRD) is a rock-fill dam with concrete slabs on its upstream face. This design provides the concrete slab as an impervious wall to prevent leakage and also a structure without concern for uplift pressure.
  8. Earth-fill dams: Earth-fill dams, also called earthen dams, rolled-earth dams or simply earth dams, are constructed as a simple embankment of well-compacted earth. A homogeneous rolled-earth dam is entirely constructed of one type of material but may contain a drain layer to collect seep water.

Major Dams in India

The major dams in India have helped the inhabitants in a number of ways like:

  1. Providing adequate water for domestic, industry and irrigation purposes.
  2. Hydroelectric power production and river navigation.
  3. These major dams in India and their reservoirs provide recreation areas for fishing and boating.
  4. They have helped in the reduction of floods.

Some facts about the issue of ageing dams

  • India is ranked third in the world in terms of building large dams.
  • Of the over 5,200 large dams built so far, about 1,100 large dams have already reached 50 years of age and some are older than 120 years.
  • The number of such dams will increase to 4,400 by 2050.
  • This means that 80% of the nation’s large dams face the prospect of becoming obsolete as they will be 50 years to over 150 years old.
  • The situation with hundreds of thousands of medium and minor dams is even more precarious as their shelf life is even lower than that of large dams.

Impact on the storage capacity

  • As dams age, soil replaces the water in the reservoirs technically known as silt or sediment.
  • Therefore, the storage capacity cannot be claimed to be the same as it was in the 1900s and 1950s.
  • To make matters worse, studies show that the design of many of our reservoirs is flawed.
  • Almost every scholarly study on reservoir sedimentation shows that Indian reservoirs are designed with a poor understanding of sedimentation science.
  • The designs underestimate the rate of siltation and overestimate live storage capacity created.
  • Therefore, the storage space in Indian reservoirs is receding at a rate faster than anticipated.

Consequences

  • When soil replaces the water in reservoirs, supply gets choked.
  • The net sown water area either shrinks in size or depends on rains or groundwater, which is over-exploited.
  • Crop yield gets affected severely and disrupts the farmer’s income.
  • The farmer’s income may get reduced as water is one of the crucial factors for crop yield along with credit, crop insurance and investment.
  • It is important to note that no plan on climate change adaptation will succeed with sediment-packed dams.
  • The flawed siltation rates demonstrated by a number of scholarly studies reinforce the argument that the designed flood cushion within several reservoirs across many river basins may have already depleted substantially due to which floods have become more frequent downstream of dams. 

Consider the question “Ageing dams poses several challenges for India. Identify these challenges and suggest the measures to deal with these challenges.” 

Conclusion

The nation will eventually be unable to find sufficient water in the 21st century to feed the rising population by 2050, grow abundant crops, create sustainable cities, or ensure growth. Therefore, it is imperative for all stakeholders to come together to address this situation urgently.

Desalination Plants and their Feasibility

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Desalination plants

Mains level: Drinking water scarcity in Urban India

Maharashtra state govt. has announced the setting up of a desalination plant in Mumbai, becoming the fourth state in the country to experiment with the idea.

Try this PYQ:

Q.What is the role of ultraviolet (UV) radiation in the water purification systems?

  1. It inactivates/kills the harmful microorganisms in water.
  2. It removes the entire undesirable odour from the water.
  3. It quickens the sedimentation of solid particles, removes turbidity and improves the clarity of water.

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

What are Desalination Plants?

  • A desalination plant turns salt water into water that is fit to drink.
  • The most commonly used techniques used for the process is reverse osmosis where external pressure is applied to push solvents from an area of high-solute concentration to an area of low-solute concentration through a membrane.
  • The microscopic pores in the membranes allow water molecules through but leave salt and most other impurities behind, releasing clean water from the other side.
  • These plants are mostly set up in areas that have access to seawater.

How widely is this technology used in India?

  • Desalination has largely been limited to affluent countries in the Middle East and has recently started making inroads in parts of the United States and Australia.
  • In India, Tamil Nadu has been the pioneer in using this technology, setting up two desalination plants near Chennai in 2010 and then 2013, while there are two more to come.

Need for such plant

  • According to the projections, the population of Mumbai is anticipated to touch 1.72 crores by 2041 and accordingly, the projected water demand would be 6424 MLD by then.
  • Currently, BMC supplies 3850 MLD as against the requirement of 4200 MLD each day.

Is it ecologically safe?

  • The high cost of setting up and running a desalination plant is one reason why the Maharashtra government has over the last decade been hesitant in building such a plant.
  • Desalination is an expensive way of generating drinking water as it requires a high amount of energy.
  • The other problem is the disposal of the byproduct — highly concentrated brine (saltwater) — of the desalination process.
  • While in most places brine is pumped back into the sea, there have been rising complaints that it ends up severely damaging the local ecology around the plant.

Back2Basics: Osmosis and Reverse Osmosis

  • Osmosis is a phenomenon where pure water flows from a dilute solution through a semi-permeable membrane to a higher concentrated solution.
  • Semi-permeable means that the membrane will allow small molecules and ions to pass through it but acts as a barrier to larger molecules or dissolved substances.
  • As water passes through the membrane to the salt solution, the level of liquid in the saltwater compartment will rise until enough pressure, caused by the difference in levels between the two compartments, is generated to stop the osmosis.
  • This pressure, equivalent to a force that the osmosis seems to exert in trying to equalize concentrations on both sides of the membrane, is called osmotic pressure.
  • If pressure greater than the osmotic pressure is applied to the high concentration the direction of water flow through the membrane can be reversed.
  • This is called reverse osmosis. Note that this reversed flow produces pure water from the salt solution since the membrane is not permeable to salt.

Kaleshwaram Lift Irrigation System (KLIS)

| Enviro & Biodiversity | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Kaleshwaram Project, Lift irrigation

Mains level: Kaleshwaram Project

The National Green Tribunal (NGT) wants a relook at Kaleshwaram Project since the Telangana government subsequently changed the design of the project.

Try this question from our AWE initiative:

The Kaleshwaram Project

  • The Kaleshwaram Lift Irrigation System is considered to be one of the world’s largest multi-purpose projects.
  • It is designed to provide water for irrigation and drinking purposes to about 45 lakh acres in 20 of the 31 districts in Telangana, apart from Hyderabad and Secunderabad.
  • This project is unique because Telangana will harness water at the confluence of two rivers with the Godavari by constructing a barrage at Medigadda in Jayashankar Bhupalpally district.
  • It would reverse pump the water into the main Godavari River and divert it through lifts and pumps into a huge and complex system of reservoirs, water tunnels, pipelines and canals.

Records to its glory

  • The project has set many records with the world’s longest water tunnels, aqueducts, underground surge pools, and biggest pumps.
  • By the time the water reaches Kondapochamma Sagar, the last reservoir in the system, the water would have been lifted to a height of 618 metres from its source at Medigadda.
  • The total length of the entire Kaleshwaram project is approximately 1,832 km of which 1,531 km is gravity canals and 203 km comprises water tunnels.

How important is KLIS to Telangana?

  • The project will enable farmers in Telangana to reap multiple crops with a year-round supply of water wherein earlier they were dependent on rains resulting in frequent crop failures.
  • This year, Telangana farmers have already delivered bumper rabi crops of paddy and maize due to better irrigation facilities and an extended monsoon.
  • KLIS covers several districts which used to face rainfall deficit and the groundwater is fluoride-contaminated.
  • Apart from irrigation, a main component of the project is the supply of drinking water to several towns and villages and also to twin cities of Hyderabad and Secunderabad.
  • Mission Bhagiratha, the Rs 43,000-crore project to supply drinking water to every household in villages, draws a large quantity of water from the KLIS and some quantity from projects on River Krishna.
  • There is a burgeoning freshwater fishing industry in the state.

Issues raised by NGT

  • The NGT has observed that the Telangana government subsequently changed the design of the project to increase its capacity.
  • By increasing its capacity to pump 3 TMC water from 2 TMC, large tracts of forest land and other land was taken over and massive infrastructure was built causing adverse impact on the environment.
  • Extraction of more water certainly requires more storage capacity and also affects hydrology and riverine ecology of Godavari River.
  • Such issues have to be examined by the statutory authorities concerned.

B2Basics

National Green tribunal

  • It is a specialised body set up under the National Green Tribunal Act (2010) for effective and expeditious disposal of cases relating to environmental protection and conservation of forests and other natural resources.
  • With the establishment of the NGT, India became the third country in the world to set up a specialised environmental tribunal, only after Australia and New Zealand, and the first developing country to do so.
  • NGT is mandated to make disposal of applications or appeals finally within 6 months of filing of the same.
  • The NGT has five places of sittings, New Delhi is the Principal place of sitting and Bhopal, Pune, Kolkata and Chennai are the other four.

Structure of NGT

  • The Tribunal comprises of the Chairperson, the Judicial Members and Expert Members. They shall hold office for term of five years and are not eligible for reappointment.
  • The Chairperson is appointed by the Central Government in consultation with Chief Justice of India (CJI).
  • A Selection Committee shall be formed by central government to appoint the Judicial Members and Expert Members.
  • There are to be least 10 and maximum 20 full time Judicial members and Expert Members in the tribunal.

  • It is a masonry gravity dam on the Periyar River in the Indian state of Kerala.
  • It is located 881 m above mean sea level, on the Cardamom Hills of the Western Ghats in Thekkady, Idukki District of Kerala.
  • It was constructed between 1887 and 1895 by John Pennycuick and also reached in an agreement to divert water eastwards to the Madras Presidency area (present-day Tamil Nadu).
  • Pennycuick is widely worshipped as a hero by farmers in the four districts of southern Tamil Nadu, where water from the dam meets the drinking water needs and irrigates thousands of hectares.

Why is the dam special?

  • The dam was constructed surmounting many odds, with malaria and thick jungles taking a toll on workers. It was a huge challenge before him to construct the dam and divert the river course.
  • Pennycuick sowed the seeds of river interlinking to bring barren and rain-starved areas under cultivation.
  • To fund dam construction, gold ornaments were donated by Chettiar families and farmers in Cumbom valley also gave their meagre savings to Pennycuick.
  • Pennycuick even sold his ancestral property in Britain and spent the amount for completing the works of the dam when the expenses exceeded the allotted funds.
  • The British government endowed him with the ‘Companion of Star of India’, a high civilian honour. He died on March 9, 1911, at Frimley in Britain.

The Delhi Development Authority (DDA) is holding public consultations for the preparation of the Master Plan for Delhi 2041 with special focus on water bodies and the land.

Try this question:      

Q.Urban water resources management is an uphill task for Indian cities. Discuss.

What is Green-Blue infrastructure?

  • ‘Blue’ infrastructure refers to water bodies like rivers, canals, ponds, wetlands, floodplains, and water treatment facilities; while ‘Green’ stands for trees, lawns, hedgerows, parks, fields, and forests.
  • The concept refers to urban planning where water bodies and land are interdependent, and grow with the help of each other while offering environmental and social benefits.

How does DDA plan to go ahead with it?

  • In the first stage, the DDA plans to deal with the multiplicity of agencies, which because of the special nature of the state, has plagued it for several years.
  • DDA wants the first map out the issues of jurisdiction, work being done by different agencies on drains and the areas around them.
  • Thereafter, a comprehensive policy will be drawn up, which would then act as the common direction for all agencies.

Why such a policy?

  • Delhi has around 50 big drains (blue areas) managed by different agencies, and due to their poor condition and encroachment, the land around (green areas) has also been affected.
  • DDA, along with other agencies, will integrate them and remove all sources of pollution by checking the outfall of untreated wastewater as well as the removal of existing pollutants.
  • A mix of mechanized and natural systems may be adopted, and dumping of solid wastes in any of these sites will be strictly prohibited by local bodies, through the imposition of penalties.

Major features

  • The land around these drains, carrying stormwater, will be declared as special buffer projects.
  • The network of connected green spaces would be developed in the form of green mobility circuits of pedestrian and cycling paths.
  • It will be developed along the drains to serve functional as well as leisure trips.

Challenges ahead

  • The biggest challenge is the multiplicity of agencies.
  • Secondly, cleaning of water bodies and drains has been a challenge for agencies in Delhi for years now.

BIS’ draft standard for drinking water supply

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: BIS

Mains level: Water supply standards in India

The Bureau of Indian Standards (BIS) has prepared a draft standard for the supply system of piped drinking water.

Try this question for mains:

Q.Climate change, scarcity, population growth, demographic changes and urbanization pose challenges for water supply systems in India. Analyse.

About the Draft

  • Labelled ‘Drinking water supply quality management system — requirements for piped drinking water supply service’, the draft has been prepared by the BIS’ Public Drinking Water Supply Services Sectional Committee.
  • It outlines the process of water supply, from raw water sources to household taps.
  • It has been developed keeping in view the Centre’s Jal Jeevan Mission for providing safe and adequate drinking water to all rural households by 2024 through tap connections.
  • It is expected to make the process of piped water supply more uniform, especially in rural and underdeveloped areas of the country where the system runs on various government orders and circulars.
  • At present, the standard is expected not to be made mandatory.

Highlights of the draft

  • The draft outlines the requirements for a water supplier or a water utility on how they should establish, operate, maintain and improve their piped drinking water supply service.
  • The process begins with the identification of a water source, which can either be groundwater or surface water sources such as rivers, streams or reservoirs.
  • It doesn’t mention how water utilities should treat the water, but states that the process should be planned in such a manner that after treatment it should conform to the Indian Standard (IS) 10500 developed by the BIS.
  • The IS 10500 outlines the acceptable limits of heavy metals such as arsenic, and other parameters like the pH value of water, its turbidity, the total dissolved solids in it, and the colour and odour.

What is the water supply process?

  • The supply system as outlined in the draft should begin with the identification of a raw water source.
  • Water should then be pumped into the treatment plant and treated to achieve acceptable drinking standards.
  • After the water is released from the plant, there should be reservoirs in the distribution system for storage of this water, and disinfection facilities to get rid of contamination at any stage of distribution.
  • Pumping stations or boosters, if necessary, should be provided to maintain adequate pressure throughout the distribution system.

District Metering Area (DMA) concept

  • The document also states that the concept of district metering area (DMA) should be adopted where possible.
  • DMA is a concept for controlling leakages in the water network, which is essentially divided into a number of sectors, called the DMAs, and where flow meters are installed to detect leaks.
  • The water supplier/utility may provide bulk water meters in the water distribution system to ensure water audit, however, the provisions should be made for domestic meters also.

What’s there in the draft in addition to the water supply process?

  • There are guidelines on water audit, which is a calculation of the amount of water put into distribution against the amount that is consumed.
  • The draft states that a water audit should be conducted on a quarterly basis.
  • Effort should be made by the water agency to bring down the water loss up to 15% of the total water supplied in the system.
  • The water utilities are also required to conduct surveys among consumers and obtain feedback on their service as per the draft.
  • Guidelines on internal audit, management review, documenting performance indicators for improvement, and timely action against non-conformity issues also find mention.

From UPSC perspective, the following things are important:

Prelims level: Bhadbhut Project, Hilsa Fish

Mains level: Not Much

The Gujarat government recently awarded the contract for a the Bhadbhut project in Bharuch, Gujarat. It has faced protests from local fishermen for its likely impact on fishing patterns, notably those of hilsa.

Make a note of major dams in India along with the rivers, terrain, major wildlife sanctuaries and national parks incident to these rivers.

What is the Bhadbhut Project?

  • It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat.
  • The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
  • The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
  • The project also aims to prevent flooding in years when rainfall is higher than normal.
  • Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
  • The project is part of the larger Kalpasar Project, which entails the construction of a 30-km dam across the Gulf of Khambhat between Bharuch and Bhavnagar districts.
  • The reservoir is meant to tap the waters of the Narmada, Mahisagar and Sabarmati.

Why are fishermen upset?

  • The barrage is expected to interfere with the migration and breeding cycle of hilsa.
  • A marine fish, hilsa migrate upstream and arrives in the brackish water of the Narmada estuary near Bharuch for spawning usually during the monsoon months of July and August, and continue doing so till November.
  • Once the barrage is built, it is expected to block its natural entry.

About Hilsa Fish

IUCN status: Least Concerned

  • The Hilsa is a species of fish related to the herring, in the family Clupeidae.
  • It is a very popular and sought-after food fish in the Indian Subcontinent.
  • Though it’s a saltwater fish, it migrates to sweet waters.
  • It is the national fish of Bangladesh and state symbol in the Indian states of West Bengal and Tripura.
  • The fish contributes about 12% of the total fish production and about 1.15% of GDP in Bangladesh.

  • They perform significant environmental, social and economic functions — from being a source of drinking water and recharging groundwater to supporting biodiversity and providing livelihoods.
  • Their role becomes even more critical in the present context when cities are facing the challenge of rapid unplanned urbanisation.
  • Their numbers are declining rapidly. For example, Bangalore had 262 lakes in the 1960s; now only 10 of them hold water.

Issues with urban water bodies

  • Natural streams and watercourses, formed over thousands of years due to the forces of flowing water in the respective watersheds, have been altered because of urbanisation.
  • As a result, the flow of water has increased in proportion to the urbanisation of watersheds.
  • Ideally, natural drains should have been widened to accommodate the higher flows of stormwater.
  • But, on the contrary, they have been a victim of various unlawful activities:

(1) Pollution

  • There has been an explosive increase in the urban population without a corresponding expansion of civic facilities such as infrastructure for the disposal of waste.
  • As more people are migrating to cities, urban civic services are becoming less adequate.
  • As a result, most urban water bodies in India are suffering because of pollution. The water bodies have been turned into landfills in several cases.
  • Guwahati’s Deepor Beel, for example, is used by the municipal corporation to dump solid waste since 2006. Even the Pallikarni marshland in Chennai is used for solid waste dumping.

(2) Encroachment

  • This is another major threat to urban water bodies. As more people have been migrating to cities, the availability of land has been getting scarce.
  • Today, even a small piece of land in urban areas has a high economic value.
  • These urban water bodies are not only acknowledged for their ecosystem services but for their real estate value as well.
  • Charkop Lake in Maharashtra, Ousteri Lake in Puducherry, Deepor beel in Guwahati are well-known examples of water bodies that were encroached.

(3) Illegal mining activities

  • Illegal mining for building material such as sand and quartzite on the catchment and bed of the lake have an extremely damaging impact on the water body.
  • For example, the Jaisamand Lake in Jodhpur, once the only source of drinking water for the city, has been suffering from illegal mining in the catchment area.
  • Unmindful sand mining from the catchment of Vembanad Lake on the outskirts of Kochi has decreased the water level in the lake.

(4) Unplanned tourism activities

  • Using water bodies to attract tourists has become a threat to several urban lakes in India.
  • Tso Morari and Pongsho lakes in Ladakh have become polluted because of unplanned and unregulated tourism.
  • Another example is that of Ashtamudi Lake in Kerala’s Kollam city, which has become polluted due to spillage of oil from motorboats.

(5) Absence of administrative framework

  • The biggest challenge is the government apathy towards water bodies.
  • This can be understood from the fact that it does not even have any data on the total number of urban water bodies in the country.
  • Further, CPCB had not identified major aquatic species, birds, plants and animals that faced threat due to pollution of rivers and lakes.

Ammonia Pollution in Yamuna River

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Nitrogen pollution

Mains level: Preventing river pollution

For the second time in a week, the Delhi Jal Board (DJB) had to reduce water production capacity by 25 per cent after high levels of ammonia were detected in the Yamuna River.

Try this PYQ from CSP 2019:

Q. Consider the following statements:

  1. Agricultural soils release nitrogen oxides into the environment.
  2. Cattle release ammonia into the environment.
  3. Poultry industry releases reactive nitrogen compounds into the environment.

Which of the statements given above is/are correct?

(a) 1 and 3 only

(b) 2 and 3 only

(c) 2 only

(d) 1, 2 and 3

What is Ammonia and what are its effects?

  • Ammonia is a colourless gas and is used as an industrial chemical in the production of fertilizers, plastics, synthetic fibres, dyes and other products.
  • Ammonia occurs naturally in the environment from the breakdown of organic waste matter, and may also find its way to ground and surface water sources through industrial effluents or through contamination by sewage.
  • If the concentration of ammonia in water is above 1 ppm it is toxic to fishes.
  • In humans, long term ingestion of water having ammonia levels of 1 ppm or above may cause damage to internal organs.

A cause of concern

  • The level of ammonia in raw Yamuna water was 1.8 parts per million (ppm).
  • The acceptable maximum limit of ammonia in drinking water, as per the Bureau of Indian Standards, is 0.5 ppm.

Where does Ammonia come from?

  • Ammonia is produced for commercial fertilizers and other industrial applications.
  • Natural sources of ammonia include the decomposition or breakdown of organic waste matter, gas exchange with the atmosphere, forest fires, animal and human waste, and nitrogen fixation processes.

How is it treated?

  • The DJB at present does not have any specific technology to treat ammonia.
  • The only solution it adapts is to reduce production at its water treatment plants.
  • In addition to this, the board mixes raw water that carries a high concentration of ammonia with a fresh supply.
  • The amount of chlorine added to disinfect raw water is also increased when high levels of ammonia are detected.

What is the long-term solution to the problem?

  • Stringent implementation of guidelines against dumping harmful waste into the river, and making sure untreated sewage does not enter the water are two things pollution control bodies are expected to do.
  • But, a more organic method agreed upon by environmentalists and experts is to maintain a sustainable minimum flow, called the ecological flow.
  • This is the minimum amount of water that should flow throughout the river at all times to sustain underwater and estuarine ecosystems and human livelihoods, and for self-regulation.
  • The lack of a minimum ecological flow also means an accumulation of other pollutants.

Ganga water improves during lockdown

| Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: BoD, CoD

Mains level: Namami Gange

The Ganga water quality has improved remarkably during the lockdown period. This highlights the importance of synergy for absolute symbiosis between nature and man as the need of the hour.

Context

  • The novel coronavirus lockdown (COVID-19) pandemic has put millions in the throes of adversity — and yet, there is a reason to celebrate.
  • Over a month into the nationwide lockdown, air and water pollution levels have shrunk and the wildlife is free.
  • Of 36 monitoring units placed in the Ganga, water quality at 27 points was found suitable for bathing and propagation of wildlife and fisheries in the lockdown period

Status of rivers in India

  • India’s water bodies are in a poor state. The rivers are becoming dumpyard for untreated sewage and industrial waste.
  • In the name of economic growth, most rivers and streams have been turned into sewer canals and are getting difficult to be treated.
  • It is estimated that every day, almost 40 million litres of wastewater enters rivers and other water bodies; only 37 per cent is adequately treated.
  • A Centre Pollution Control Board (CPCB) report showed that critically polluted river stretches in the country have increased from 302 stretches in 2016 to 351 stretches in 2018.
  • The finding was based on Biological Oxygen Demand (BOD).

Ganga

  • According to CPCB, more than half of wastewater treatment plants in the basin do not comply with the discharge norms.
  • Since 1985, several programmes and schemes have been launched to clean the Ganga. It began with the Ganga Action Plan I, followed by Ganga Action Plan II.

  • In 2015, the biggest-ever initiative, Namami Gange was launched with a budget of over Rs 20,000.
  • Despite numerous programmes and huge funds, the Ganga still runs polluted.

The causes

  • More than 80 per cent of pollution in the Ganga is due to domestic sewage from surrounding towns and villages. The rest is contributed by industrial waste.
  • During the lockdown, domestic sewage would have increased owing to increased demand for water to maintain hand-washing hygiene. Industrial waste, however, stopped entering the Ganga.
  • Other activities such as tourism, fairs, bathing and cloth washing near the ghats were curtailed. Experts said these observations reflected that domestic sewerage was not the only cause of concern.
  • When sewage is mixed with industrial effluents, it gets difficult for the river to assimilate pollution.
  • One more reason was high number of western disturbances which brought rain and improved the flow in the river leading to dilution.

COVID-19’s gift to Ganga

  • After the nationwide lockdown was imposed, within 10 days signs of improvement in water quality started surfacing.
  • At Varanasi’s Nagwa Nala, the Dissolved Oxygen (DO) values were found increased to 6.8 milligram/litre against 3.8 mg/l on March 6, showcasing an extraordinary improvement of 79 per cent in DO values.
  • 30 per cent of the total BOD load was due to industries along the river, which amounted to 130-150 tons per day.
  • Since all major polluting industries are closed, the toxic load is off the river.

Surprisingly better

  • Ganga water at Haridwar and Rishikesh was reported fit for drinking due to 500 per cent decrease in sewage and industrial effluents.
  • A dip in the number of visitors at ghats in Haridwar also helped the river water quality.
  • The Ganga water has become fit for ‘achaman’, which means ritual sipping, after a long time.

Bringing the ambitions to reality

There is an urgent need to:

  • Reinvestigate the main source of pollution in Ganga and reorient all river cleaning policies and programmes based on lockdown findings.
  • Industries need to strictly adhere to discharge norms accompanied with strong enforcement of laws and regulations vis-a-vis strong monitoring and vigilance framework.
  • Setting up of effective interventions to clean rivers, reliable, representative and comprehensive data collected at high frequency in a disaggregated manner.
  • There is an urgent need to expand the network of monitoring stations on the Ganga, the Yamuna and tributaries of Ganga in more places.
  • Over-extraction and over-exploitation of Ganga’s waters have rendered long stretches of the river completely dry for much of the year. There is a need to maintain ecological flow to keep it clean for longer run.
  • Education and awareness needs to be carried out strategically.

Back2Basics: Biochemical Oxygen Demand

  • BOD is the amount of dissolved oxygen needed (i.e. demanded) by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period.
  • The BOD value is most commonly expressed in milligrams of oxygen consumed per litre of sample during 5 days of incubation at 20 °C and is often used as a surrogate of the degree of organic pollution of water.
  • BOD is similar in function to chemical oxygen demand (COD), in that both measure the amount of organic compounds in water.
  • However, COD is less specific, since it measures everything that can be chemically oxidized, rather than just levels of biodegradable organic matter.

[pib] Law for Rain Water Harvesting

PIB | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Law for Rain Water Harvesting

Mains level: Rooftop water conservation strategy

 

 

The Ministry of Housing & Urban Affairs has issued the Model Building Bye Laws, 2016 for guidance of the States/UTs and has a chapter on ‘Rainwater Harvesting’.

Why such move?

  • These laws aim to regulate the over-exploitation and consequent depletion of ground water.
  • It would enable States/UTs to enact suitable ground water legislation for regulation of its development, which includes provision of rain water harvesting.

About the Bye Laws

  • 33 States/UTs have adopted the rainwater harvesting provisions.
  • The provisions of this chapter are applicable to all the buildings.

Various provisions

  • As per Model Building Bye Laws- 2016, provision of rainwater harvesting is applicable to all residential plots above 100 sq.m.
  • Water being a State subject, initiatives on water management including conservation and water harvesting in the Country is primarily States’ responsibility.
  • So the implementation of the rainwater harvesting policy comes within the purview of the State Government/Urban Local Body / Urban Development Authority.

Back2Basics

Groundwater governance in India

  • Central Ground Water Authority (CGWA) has been constituted under Section 3(3) of the ‘Environment (Protection) Act, 1986’ for the purpose of regulation and control of groundwater development and management in the Country.
  • CGWA is regulating ground water withdrawal by industries/infrastructure/ mining projects in the country for which guidelines/ criteria have been framed which includes rainwater harvesting as one of the provisions while issuing No Objection Certificate.

Debating water quality

op-ed snap | Governance | Mains Paper 2: Governance, Transparency & Accountability, Citizens Charters,Government Scheme/Policies
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Not much.

Mains level: Paper 2- Jal Jeevan Mission, ensuring quality drinking water.

Context

The competitive politics of Delhi election has brought the issue of drinking water to centre stage.

Controversy over BIS water status report

  • Politicising of the report: The controversy started with the release of the BIS report for 21 major Indian cities, in keeping with the objectives of the ‘Jal Jeevan Mission’.
    • The mission aims to provide safe piped water to all households by 2024.
    • The fact that drinking water in Delhi was ranked the most unsafe, as the samples failed in 19 out of 28 parameters, was challenged by the Government of Delhi and the Delhi Jal Board (DJB).
  • Compilation of information on the existing status: The study is scheduled to cover all districts in the country within a year. Supply of potable water obviously requires first compilation of information on the existing status
  • Water as an urgent concern: The fact that water should be treated as an urgent concern for public health and the ecosystem of the country cannot be denied.
  • Imperceptible threat: The threats to human health due to poor water quality, except when they appear as an epidemic, are largely imperceptible.
    • This generally subjects the population to subtle health problems without its knowledge or consent.

Pollution and water crisis in India

  • Pollution contributing to water crisis: India is on the throes of a severe water crisis, not only because of a gradual reduction in per capita availability of water due to a rising population but also because of rising and unchecked pollution in the country’s rivers and water bodies.
    • It is a fact which is mostly overlooked in the deliberations on water resources management.
  • Only 30% sewage treatment capacity in major cities: As per published estimates of the Central Pollution Control Board, the country has a treatment capacity of only about 30% of sewage generated in the major cities.
    • Not to talk of other urban and rural areas where the sewage finds its way to local water bodies or rivers without treatment.

Impending water stress in the country

  • NITI Aayog report: A 2018 Report of the NITI Aayog has observed that currently, 600 million Indians face high to extreme water stress.
    • The report also states that about two lakh people die every year due to inadequate access to safe water.
  • Demand twice the supply by 2030: The crisis is only going to get worse.
    • By 2030, the country’s water demand is projected to be twice the available supply, implying severe water scarcity for hundreds of millions of people.
  • High methane in Yamuna water in Delhi: For the water coming from the Yamuna released from Haryana, the DJB has to often stop the supply for a few days if the concentration of methane goes up beyond a certain level.
    • This is because the tri-chloromethane that may be produced during the disinfection process is highly carcinogenic.
    • The effect may surface on human health not immediately but over a period of time.

The capital’s high pollutant load and need for improvement in governance

  • Contributing 50% pollutant: Delhi, which constitutes less than 1% of the total catchment of the Yamuna, contributes more than 50% of total pollutant load in the river.
    • Delhi has 7,000 km of sewer line as on date, against a requirement of 24,000 km.
    • The 17 sewage treatment plants being operated by the DJB are able to take care of not more than 30% of sewage treatment.
  • There is no sewerage system at all for over 45% of the population in unauthorised and even regularised colonies and rural areas.
  • As of now, there are 18 major drains carrying sewage, garbage and industrial effluents into the Yamuna.
  • Solid waste dumping in Yamuna: It is not only the untreated sewage water and industrial effluents, but also the solid wastes and construction material discharged by individuals, companies and municipal bodies that have caused the suffocation of the Yamuna.
    • Also, floodplains have been encroached upon by settlements.
  • Challenge of supplying quality water: Ensuring the supply of quality drinking water is not only expensive, but it also needs improvement in governance.
    • It needs technical knowledge on measurement and regulation of water quality.
    • It is not the fault of the DJB or the Delhi government alone that they have not been able to ensure a 100% supply of quality water to the citizens of Delhi.
    • Given the constraints they face, especially those concerning the water resources management and laws in the country.

Conclusion

The Jal Jeevan Mission, even if it has not been so far structured, conceptualised and funded adequately, has begun the important work of gathering information on the scale and scope of the problem and making it available in an open and transparent manner. The best outcome is that the competitive politics of the Delhi election has ensured a political debate on water quality.

Note4Students

From UPSC perspective, the following things are important:

Prelims level: Jalyukta Shivar Abhiyan

Mains level: Various schemes for drought management

 

 

Jalyukta Shivar, the flagship water conservation project launched by the earlier government has been officially scrapped by the present Maha government.

What is Jalyukta Shivar?

  • Launched in December 2014 after Maharashtra experienced consecutive droughts, the project aimed at rolling out measures that could potentially mitigate water scarcity in the most drought-prone villages in a systematic manner.
  • Nearly 52 per cent of the state’s geographical area is prone to drought, either naturally or due to poor rainfall.
  • This includes Marathwada and adjoining areas of Madhya Maharashtra and large parts of Vidarbha.
  • The project targeted strengthening and streamlining existing water resources like canals, bunds and ponds by arresting maximum run-off rainwater during monsoon.
  • Tasks to widen and deepen natural water streams and connect them to nearby water storage facilities like earthen or concrete check-dams were proposed.
  • In the first phase, planned during 2015 – 2019, Jalyukta Shivar envisaged making 5,000 villages drought-free, every year.
  • During its proposed tenure, the government eyed at making 25,000 drought-prone villages water-sufficient.

Was Jalyukta Shivar beneficial?

  • While the exact number of villages that were declared drought-free remains unknown, the programme attempted to bring water stress down in a majority of the most water-scarce villages in the state.
  • In January last year, then CM had announced that the scheme had transformed 16,000 drought-prone villages of Maharashtra.

What is the future of water conservation in the state?

  • Geologists and hydrologists, who worked on implementing the project, shared similar views and hailed Jalyukta Shivar.
  • This was mainly due to the interventions undertaken in the existing water reserves, planned de-silting activities, among many others.
  • However, experts agreed that the scheme was not appropriately implemented.
  • Now with Jalyukta Shivar no longer in existence, focused efforts of the past five years, in most likelihood, will go down the drain unless a similar scheme is introduced.
  • With rainfall variations getting more pronounced, in addition to depleting groundwater reserves, the state will need concrete interventions to tackle future water requirements.

The Government of India and the World Bank have signed a $450 million loan agreement to support the national programme to arrest the country’s depleting groundwater levels and strengthen groundwater institutions.

About the Programme

  • The World Bank-supported programme will be implemented in the states of Gujarat, Maharashtra, Haryana, Karnataka, Rajasthan, Madhya Pradesh, and Uttar Pradesh and cover 78 districts.
  • These states span both the hard rock aquifers of peninsular India and the alluvial aquifers of the Indo-Gangetic plains.
  • They were selected based on several criteria, including degree of groundwater exploitation and degradation, established legal and regulatory instruments, institutional readiness, and experience in implementing initiatives related to groundwater management.
  • This programme will contribute to rural livelihoods and in the context of climatic shifts, build resilience of the rural economy.

Objectives

The programme will, among others, enhance the recharge of aquifers and introduce water conservation practices; promote activities related to water harvesting, water management, and crop alignment; create an institutional structure for sustainable groundwater management; and equip communities and stakeholders to sustainably manage groundwater.

Particulars of the programme

  • The programme will introduce a bottom-up planning process for community-driven development of water budgets and Water Security Plans (WSPs).
  • Water budgets will assess surface and groundwater conditions (both quantity and quality) and identify current and future needs.
  • The WSP, on the other hand, will focus on improving groundwater quantity and incentivize selected states to implement the actions proposed.
  • Such community-led management measures will make users aware of consumption patterns and pave the way for economic measures that reduce groundwater consumption.
  • Crop management and diversification will be the other focus areas.

Arsenic Contamination

DOMRStates | Governance | Mains Paper 2: Health & Education
Note4Students

From UPSC perspective, the following things are important:

Prelims level: Arsenic poisoning and its effects on food chain

Mains level: Groundwater contamination

As the geography of arsenic contamination spreads, there is an urgent need for governments to reorient mitigation measures. That’s because the focus till now has only been on drinking water, but new research says arsenic has contaminated our food chain.

Arsenic contamination of water

  • Arsenic contamination in groundwater is one of the most crippling issues in the drinking water scenario of India.
  • According to the latest report of the Central Ground Water Board (CGWB), 21 states across the country have pockets with arsenic levels higher than the BIS stipulated permissible limit of 0.01 milligram per litre (mg/l).
  • The states along the Ganga-Brahmaputra-Meghna (GBM) river basin — Uttar Pradesh, Bihar, Jharkhand, West Bengal and Assam — are the worst affected by this human-amplified geogenic occurrence.
  • In India, arsenic contamination was first officially confirmed in West Bengal in 1983.
  • Close to four decades after its detection, the scenario has worsened.
  • About 9.6 million people in West Bengal, 1.6 million in Assam, 1.2 million in Bihar, 0.5 million in Uttar Pradesh and 0.013 million in Jharkhand are at immediate risk from arsenic contamination in groundwater.

Effects of arsenic poisoning

  • Long-term exposure to arsenic in drinking water can cause cancer in the skin, lungs, bladder and kidney. It can also cause other skin changes such as thickening and pigmentation.
  • The likelihood of effects is related to the level of exposure to arsenic and in areas where drinking water is heavily contaminated, these effects can be seen in many individuals in the population.
  • Increased risks of lung and bladder cancer and skin changes have been reported in people ingesting arsenic in drinking water at concentrations of 50 µg/litre, or even lower.

Affecting food

  • Recent research says arsenic contamination in groundwater has penetrated the food chain.
  • It eventually causes photo-accumulation of arsenic in the food crops, especially in the leaves, can emanate from contaminated water sprayed on them.
  • Yet the focus remained on drinking water, and the affected regions became the primary stake-holder in the mitigation approach.

Way forward

  • Mitigation measures — that are currently focused on drinking water — must have a more comprehensive approach to ensure arsenic-free water for drinking and agricultural products.
  • That means that the government must check for arsenic in water used for agricultural produce.
  • Both the Union and state governments must work toward facilitating research that can investigate the accumulation of arsenic in crops and addressing the agricultural concerns of the affected regions.
  • They must watch out for arsenic percolation in the food chain and the possibilities of biomagnification.
  • The government needs to also conduct a larger study on the arsenic contamination of our food chain and its health impacts to understand its spatial spread through the agricultural supply chain.

Energy stored in wastewater

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia
Note4Students

From UPSC perspective, the following things are important:

Prelims level: UNU-INWEH

Mains level: Need for wastewater management

The world generates about 380 trillion litres (tl) wastewater every year. These stores vast amounts of energy, nutrients for fertilizers besides, of course, water, according to recent study by the UN Institute for Water Environment and Health (UNU-INWEH).

Energy in wastewater

  • In principle, nutrients such as nitrogen, phosphorous and potassium recovered from wastewater produced annually can offset 13.4 per cent of global demand to produce fertilizers.
  • Assuming full-energy recovery, the study estimated, current wastewater volume could provide enough methane fuel to power 196 million households by 2030 and 239 million households by 2050.
  • Usable water reclaimed from wastewater can irrigate up to 31 million hectares (mha) of land, the study claimed.
  • The volume of wastewater being generated is projected to rise roughly 24 per cent by 2030 to 470 tl and 51 per cent by 2050 to 574 tl.
  • Treating wastewater efficiently can go a long way in achieving the UN-mandated sustainable development goals (SDG).

About UNU-INWEH

  • UNU-INWEH acts as the “UN Think Tank on Water” and contributes to the resolution of the global water challenge through a unique programme of applied research and education.
  • It conceives, develops, and manages water initiatives that help developing countries build their capacity for lasting improvements in human and ecosystem health, and overall reduction in poverty.
  • The  University is not a traditional university in the sense of having a faculty, campus, or students.
  • They respond directly to the regional and global water crisis and facilitate efforts to meet UN Development goals by providing a scientific evidence base.
  • UNU-INWEH carries out its work in cooperation with other research institutions, international organizations, individual scholars, and scientists throughout the world.

  • The project will store around 781 million cubic meters of water of river Ujh, a tributary of river Ravi.
  • It aims to provide uninterrupted water for irrigation to farmers in J&K’s Kathua district and to produce power.
  • After completion of the project, utilization of waters of eastern rivers allotted to India as per the Indus Water Treaty would be enhanced by utilising the flow that presently goes across the border to Pakistan.

Indus Waters Treaty, 1960

  • The IWT is a water-distribution treaty between India and Pakistan, brokered by the World Bank signed in Karachi in 1960.
  • According to this agreement, control over the water flowing in three “eastern” rivers of India — the Beas, the Ravi and the Sutlej was given to India
  • The control over the water flowing in three “western” rivers of India — the Indus, the Chenab and the Jhelum was given to Pakistan
  • The treaty allowed India to use western rivers water for limited irrigation use and unrestricted use for power generation, domestic, industrial and non-consumptive uses such as navigation, floating of property, fish culture, etc. while laying down precise regulations for India to build projects
  • India has also been given the right to generate hydroelectricity through run of the river (RoR) projects on the Western Rivers which, subject to specific criteria for design and operation is unrestricted.

Present Status of Development

  • To utilize the waters of the Eastern rivers which have been allocated to India for exclusive use, India has constructed Bhakra Dam on Satluj, Pong and Pandoh Dam on Beas and Thein (Ranjitsagar) on Ravi.
  • These storage works, together with other works like Beas-Sutlej Link, Madhopur-Beas Link, Indira Gandhi Nahar Project etc has helped India utilize nearly entire share (95 %) of waters of Eastern rivers.
  • However, about 2 MAF of water annually from Ravi is reported to be still flowing unutilized to Pakistan below Madhopur.
  • The three projects will help India to utilize its entire share of waters given under the Indus Waters Treaty 1960:

I. Resumption of Construction of Shahpurkandi project

  • It is a dam project under construction on Ravi River.

II. Construction of Ujh multipurpose project

  • It is a dam project under construction on Ujh, a tributary of Ravi River.

III. 2nd Ravi Beas link below Ujh

  • This project is being planned to tap excess water flowing down to Pakistan through river Ravi, even after construction of Thein Dam.
  • It aims constructing a barrage across river Ravi for diverting water through a  tunnel link to Beas basin.
