  • NGT Report on Ganga Water Quality

    Why in the News?

    The National Green Tribunal (NGT) has raised concerns over the water quality of the Ganga at Triveni Sangam in Prayagraj, Uttar Pradesh. The river is failing to meet bathing standards due to high Biological Oxygen Demand (BOD) and faecal coliform contamination.

    Key Findings of the Ganga Water Quality Assessment at Triveni Sangam:

    • Water is unsafe for bathing as per Central Pollution Control Board (CPCB) standards.
    • BOD levels exceeded the permissible limit of 3 mg/L on multiple days in January 2025.
    • Government releasing 10,000-11,000 cusecs of fresh water to improve quality.
    • Faecal coliform levels (E. coli) far exceed safe limits due to sewage contamination.
    • Safe limit: 2,500 MPN/100 ml; Detected levels: 49,000 MPN/100 ml (Ganga) and 33,000 MPN/100 ml (Yamuna).

    What is Biological Oxygen Demand (BOD)?

    • BOD measures the amount of oxygen required by bacteria to break down organic matter in water.
    • Higher BOD levels indicate higher organic pollution, which can lead to oxygen depletion and aquatic life destruction.
    • Safe limit for bathing water is below 3 mg/L.
    • Excessive BOD levels suggest sewage, industrial waste, or decomposing organic matter contamination.
    • BOD levels above safe limits can cause waterborne diseases and disrupt aquatic ecosystems.

    PYQ:

    [2017] Biological Oxygen Demand (BOD) is a standard criterion for:

    (a) Measuring oxygen levels in blood

    (b) Computing oxygen levels in forest ecosystems

    (c) Pollution assay in aquatic ecosystems

    (d) Assessing oxygen levels in high-altitude regions

     

  • Parliamentary Panel recommends Paddy Residue MSP to curb Stubble Burning

    Why in the News?

    Recently, a parliamentary committee, led by Rajya Sabha MP Milind Deora, has suggested setting a minimum support price (MSP) for paddy residue. This aims to discourage farmers from burning stubble, which is a major cause of air pollution in Delhi.

    What were the observations made by the Parliamentary standing committee?

    • Stubble Burning as a Key Cause of Air Pollution: The committee acknowledged that stubble burning in Punjab and Haryana significantly contributes to Delhi’s air pollution during winter.
    • Farmers’ Constraints: Farmers burn stubble due to a short window (25 days) between paddy harvesting and wheat sowing.
    • State-wise Disparities: Punjab generates 16.1 million tonnes of non-basmati paddy straw annually, while Haryana generates only 4.04 million tonnes. Punjab also reported 10,990 stubble-burning incidents in 2023-24, compared to Haryana’s 1,406.
    • Existing Government Schemes: The Central government provides subsidies for crop residue management machinery, but high fuel costs make their usage unfeasible for many farmers.
    • Incentive Gap: Haryana provides higher financial support (₹7,000/acre for crop diversification, ₹4,000 for direct seeding of rice), whereas Punjab offers only ₹1,500 for direct seeding.
    • Technological Gaps: Even after mechanized harvesting, 10-15 cm of stubble remains in fields, which cannot be manually cleared due to labour shortages.

    What recommendations were given by the Panel?

    • Minimum Price for Paddy Residue: Establish a mechanism to determine a minimum price for paddy residue, similar to the Minimum Support Price (MSP) for crops, in consultation with the Commission for Air Quality Management (CAQM). The benchmark price should be announced before the Kharif season to reflect residue collection costs.
    • Promote Short-Duration Paddy Varieties: Urge state governments to promote short-duration paddy varieties instead of long-duration ones like PUSA 44.
    • Unified National Policy: Implement a unified national policy to integrate agricultural residue into bioenergy generation, ensuring inter-ministerial coordination.
    • Real-time Forecasting: Establish real-time mapping of crop acreage and forecasting of crop maturity and weather patterns to estimate land under cultivation and assess district-wise crop yields for better planning.
    • Storage Facilities: Set up interim storage facilities in districts where industries or end-users are not available within a 20–50 km range to facilitate efficient crop residue collection and transport.
    • Incentives and Subsidies: Provide incentives for the transportation of stubble to discourage in-field burning and subsidize machinery for in-situ paddy straw management. Farmers should get a 50 percent subsidy for machinery and 80 percent for establishing centers for renting out machines for managing paddy straw.
    • Technological Advancements: Develop technology that combines the work of harvesters and cutters to completely clear stubble from fields and promote early-maturing crop varieties.

    What is Delhi govt’s 20-point Winter Action Plan?

    • Real-Time Monitoring and Special Task Force: The plan includes the use of drones for real-time monitoring of pollution hotspots, marking a shift from manual inventory methods. Additionally, a special task force will be formed to oversee pollution control efforts and ensure compliance with regulations across various sectors.
    • Control Measures for Pollution Sources: The action plan emphasizes controlling dust pollution through increased water sprinkling, deployment of anti-smog guns, and strict regulations on construction sites. It also addresses vehicular emissions by promoting work-from-home policies and considering the implementation of an odd-even vehicle rationing scheme during high pollution days.
    • Public Participation and Emergency Measures: The plan encourages public involvement through campaigns and initiatives aimed at reducing pollution, such as banning firecrackers and promoting eco-friendly practices.
      • Emergency measures like artificial rain are also proposed to mitigate severe pollution events expected around Diwali and during stubble burning seasons.

    Way forward: 

    • Sustainable Agricultural Practices & Farmer Incentives: Strengthen financial incentives for crop residue management, promote widespread adoption of short-duration paddy varieties, and enhance technological solutions for complete stubble removal to reduce reliance on burning.
    • Integrated Pollution Control & Public Awareness: Implement a coordinated air quality management framework involving real-time monitoring, stricter enforcement of emission norms, and large-scale public participation campaigns to promote eco-friendly practices and behavioural change.

    Q Mumbai, Delhi and Kolkata are the three Mega cities of the country but the air pollution is much more serious probelm in Delhi as compared to the other two. Why is this so? (UPSC IAS/2015)

  • What is the Aravalli Safari Park Project?

    Why in the News?

    The Haryana government has proposed an ambitious 3,858-hectare Aravalli Safari Park spread across Gurugram and Nuh, which aims to be the world’s largest safari park.

    About the Aravalli Range

    • The Aravalli Range is one of the oldest fold mountain ranges in the world, dating back to the Proterozoic era.
    • It stretches 692 km from Gujarat to Delhi, passing through Rajasthan and Haryana.
    • The range acts as a natural green barrier, preventing the expansion of the Thar Desert into eastern Rajasthan and the Gangetic plains.
    • Highest Peak: Guru Shikhar (1,722 meters) in Mount Abu, Rajasthan.
    • Rivers originating from the Aravalli Range:
      • Banas and Sahibi Rivers (tributaries of the Yamuna).
      • Luni River, which flows into the Rann of Kutch.
    • Rich in mineral resources, including copper, zinc, lead, and marble.
    • The Aravalli hills play a critical role in groundwater recharge, acting as natural aquifers.
    • 80% of the range is in Rajasthan, while the rest is in Haryana, Delhi, and Gujarat.

    What is the Aravalli Safari Park Project?

    • The Haryana government has proposed a 3,858-hectare Aravalli Safari Park, intended to be the world’s largest.
    • The project covers 2,574 hectares in Gurugram and 1,284 hectares in Nuh.
    • It will include animal enclosures, botanical gardens, aquariums, cable cars, hotels, and an animal hospital.
    • Initially managed by the Tourism Department, the project is now under the Forest Department, with an expert committee overseeing its execution.

    Why is there Opposition?

    • Ecological Concerns: The Aravallis prevent desertification, and large-scale construction could disrupt groundwater recharge and biodiversity.
    • Threat to Water Security: The region acts as an aquifer, and excessive tourism, vehicular traffic, and construction could worsen Gurugram and Nuh’s water crisis, already classified as “over-exploited” by the Central Ground Water Board.
    • Legal Violations: The project falls under protected forest areas, governed by:
      • Forest Conservation Act, 1980.
      • Punjab Land Preservation Act (PLPA), 1900, restricting deforestation.
      • T.N. Godavarman Thirumulpad Judgment (1996), which extends legal protection to non-notified forest land.

  • [7th February 2025] The Hindu Op-ed: The saga of regulating India’s thermal power emissions

    PYQ Relevance:

    Q) Describe the benefits of deriving electric energy from sunlight in contrast to the conventional energy generation. What are the initiatives offered by our government for this purpose? (UPSC CSE 2020)

     

    Mentor’s Comment: UPSC mains have always focused on Environmental Impact Assessment studies (2015), and conventional energy generation (2020).

    On December 30, 2024, the MoEFCC extended the deadline for thermal plants to meet SO₂ emission norms by three years without explanation. Originally set for December 31, 2024, this delay affects 20 GW of plants near densely populated areas. These norms were set in 2015 to tighten particulate matter limits and introduced SO₂ norms for the first time, aligning them with standards in countries like Australia, China, and the U.S., despite the short timeline for compliance.

    Today’s editorial talks about the revised emission norms for Indian thermal plants and impact of these norms. This content will help in GS Paper 3.

    _

    Let’s learn!

    Why in the News?

    On December 30, 2024, India’s Ministry of Environment, Forest and Climate Change (MoEFCC) changed the Environment Protection Rules, extending the deadline for thermal power plants to meet sulphur dioxide (SO₂) emission standards by three years without providing any explanation.

    What are the revised emission norms for Indian thermal plants?

    • New Deadlines: On December 30, 2024, India’s Ministry of Environment, Forest and Climate Change (MoEFCC) extended the deadlines for thermal power plants to comply with sulphur dioxide (SO₂) emission norms by three years. The revised deadlines are:
      • Category A (By Dec 31, 2027) – Thermal plants within 10 km of NCR or cities with over 1 million population (e.g., Dadri NTPC, Koradi) must comply first due to high pollution and population density.
      • Category B (By Dec 31, 2028) – Plants in critically polluted areas or non-attainment cities (e.g., Singrauli, Korba, Chandrapur) get extended timelines due to severe environmental concerns.
      • Category C (By Dec 31, 2029) – All other plants (e.g., Talcher, Mundra, Simhadri) must comply last as they are in lower-risk areas with relatively better air quality.
    • Historical Context: The original norms were established in December 2015, with an initial compliance deadline set for December 2017. This was later extended multiple times due to various challenges.

    Note: The categories for compliance with SO₂ emission norms for Indian thermal power plants are based on location and environmental impact.

    What are the challenges around implementing the flue gas desulphurisation (FGD) technology?

    • Technical and Financial Hurdles: The implementation of FGD technology has faced delays primarily due to high costs, inadequate supply chains, and operational complexities. Many plants tendered contracts for FGDs but did not progress at a pace necessary to meet earlier deadlines.
    • Debate on Necessity: Recent studies commissioned by NITI Aayog and conducted by CSIR-NEERI have questioned the urgency and necessity of FGD installations for improving air quality, suggesting that focus should instead be on particulate emissions. This has led to confusion and varied interpretations of compliance requirements among stakeholders.

    How successful has India been in implementing emission norms for thermal power plants?

    • Limited Progress: As of late 2024, only about 22 GW of thermal capacity had installed FGDs, which is less than 8% of the total coal-fired power generation capacity in India. The overall progress has been slower than anticipated since the introduction of the norms.
    • Compliance Monitoring Issues: There is a lack of transparency regarding adherence to existing norms, as pollution control boards have not consistently verified compliance. This raises concerns about the effectiveness of regulatory oversight.

    What are the economic and environmental consequences of noncompliance and what measures are in place to address this?

    • Health Impacts: The extension of compliance deadlines poses risks to public health, especially in densely populated areas like Delhi-NCR, where air pollution is already a critical issue. SO₂ is known to contribute to respiratory and cardiovascular diseases.
    • Financial Burden on Consumers: Electricity regulators have allowed thermal plants to pass on the costs of installing FGDs to consumers, regardless of whether emission norms are met. This means consumers may end up paying for pollution control equipment that remains unused due to extended compliance timelines.
    • Environmental Compensation: For non-compliance beyond specified timelines, MoEFCC has introduced an environmental compensation scheme that penalizes plants based on their duration of non-compliance. This includes fees that escalate over time but may not be sufficient to incentivize timely compliance.

    Way forward: 

    • Strict Enforcement & Incentives – Strengthen regulatory oversight with real-time emissions monitoring, enforce penalties for non-compliance, and provide financial incentives or subsidies to accelerate FGD adoption.
    • Balanced Policy Approach – Address technical and financial barriers by improving supply chains, supporting domestic FGD manufacturing, and ensuring a phased yet firm transition while prioritising high-risk areas.

  • What is the SC directive on sacred groves?

    Why in the News?

    On December 18, 2024, the Supreme Court ordered Rajasthan’s Forest Department to map all sacred groves using satellite and ground surveys based on their cultural and ecological importance, regardless of their size.

    Note: In Rajasthan, sacred groves, locally known as ‘orans’, are estimated to number around 25,000, covering approximately 6 lakh hectares across the state.

    What are the implications of the December 18 order? 

    • Conflict with the Forest Rights Act (FRA), 2006 – The order contradicts the FRA, which was enacted to recognize and vest forest rights with gram sabhas. Instead, the decision shifts control from communities to the Forest Department.
    • Loss of Community Autonomy – Sacred groves, which have been traditionally protected by local communities, will now be governed by state authorities, potentially disrupting cultural conservation practices.
    • Potential Erosion of Traditional Governance Systems – The transfer of management could weaken customary laws and traditional conservation practices that have preserved these groves for generations.
    • Legal Precedence for Future Cases – By prioritizing the Wildlife Protection Act (WLPA), 1972, over the FRA, this order may set a precedent for other community-managed lands to be taken over by the Forest Department.
    • Impact on Livelihoods and Religious Practices – Communities that depend on sacred groves for religious, medicinal, and cultural purposes may face restrictions under the new classification as ‘community reserves’.

    What did T.N. Godavarman v. Union of India establish about the definition of ‘forest land’? 

    • Broad Definition: The Supreme Court established that ‘forest land’ includes not only areas understood as forests in the dictionary sense but also any area recorded as forest in government records, regardless of ownership.
    • Expert Committees: The ruling directed state governments to form expert committees to identify areas that fit this definition of ‘forest land’.

    How are sacred groves traditionally conserved by communities?

    • Watershed & Ecological Functions: Many sacred groves protect natural water sources, prevent soil erosion, and regulate local climate. Example: Orans (Rajasthan) – These groves support perennial water streams and serve as critical grazing lands for livestock.
    • Strict Protection through Customary Laws & Taboos: Communities impose strict prohibitions on tree felling, hunting, or resource extraction in sacred groves. Example: Sarpa Kavu (Kerala) – These groves are dedicated to serpent deities, and cutting trees is considered a bad omen.
    • Religious & Cultural Practices for Conservation: Rituals, festivals, and community prayers reinforce the spiritual importance of these groves. Example: Devara Kadu (Karnataka) – Annual worship ceremonies maintain local participation in conservation efforts.
    • Community Governance & Management: Local elders, priests, or village councils oversee the maintenance and enforcement of protection norms. Example: Jahera (Odisha, Chhattisgarh) – Tribal communities like the Gonds and Santhals manage these groves as sacred spaces.
    • Role in Biodiversity Preservation: The groves act as biodiversity hotspots, protecting endemic flora, fauna, and medicinal plants. Example: Law Kyntang (Meghalaya) – Khasi communities conserve these forests, which shelter rare orchids and medicinal herbs.

    Way forward:

    • Harmonizing Legal Frameworks – Amend policies to ensure the Forest Rights Act (FRA), 2006, and Wildlife Protection Act (WLPA), 1972, work in tandem, recognizing gram sabhas’ authority in managing sacred groves while ensuring ecological conservation.
    • Community-Centric Conservation – Strengthen traditional governance systems by legally empowering local communities to manage sacred groves, integrating scientific conservation methods with cultural practices.
