  • Is groundwater contamination high in India?

    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.

  • Tirupati stampede: Why stampedes take place, how to mitigate risks

    Why in the News?

    Recently six people lost their lives in a stampede in Tirupati while waiting to collect tokens for Lord Venkateswara’s darshan.

    Why do stampedes take place?

    Stampedes are chaotic and uncontrolled movements of large crowds, often triggered by panic or an urgent rush to move in a confined or crowded space.

    • Venues that exceed their safe capacity can lead to dangerously crowded conditions. When too many people gather in a confined space, the risk of a stampede increases significantly.
    • Inadequate planning and lack of effective crowd control measures, such as clear exits and designated waiting areas, can exacerbate the situation. Poor organisation often leads to confusion and panic among attendees.
    • Narrow pathways, obstacles, and poorly designed event spaces can create bottlenecks during emergencies. These barriers make it difficult for people to move freely and can trap crowds, increasing the risk of crush injuries.

    How does human psychology lead to stampedes?

    • Panic Response: Panic can spread rapidly through crowds, causing individuals to act irrationally. When one person begins to push forward out of fear or urgency, it creates a domino effect where others follow without understanding the situation.
    • External Triggers: Events such as loud noises, sudden movements, or perceived threats (like a fire or an emergency) can trigger panic responses in crowds, leading to stampedes.
    • Psychological Factors: Theories of collective behaviour suggest that in large groups, individuals may act against their own interests when panic sets in.
      • For instance, the desire to escape a perceived danger can override cooperative behaviour, leading to chaotic pushing and shoving.

    How does the physical organisation of spaces contribute to stampedes?

    • Narrow Exits and Blocked Pathways: Limited exits and narrow pathways can create bottlenecks during emergencies, making it difficult for individuals to evacuate quickly.
      • When a crowd is forced to funnel through a small area which leads to panic and chaos, increasing the likelihood of a stampede as people rush to escape.
    • Poorly Designed Crowd Flow: Spaces that do not effectively manage crowd flow can exacerbate congestion.
      • Suppose different groups of people converge at the same point without clear guidance or separation that can lead to confusion and a surge of movement, triggering stampede conditions. Effective crowd management strategies are essential to ensure smooth movement.
    • Inadequate Lighting and Visibility: Insufficient lighting can disorient attendees and hinder their ability to navigate the space safely. In low-light conditions, individuals may struggle to see exits or understand the crowd dynamics, leading to increased panic and disorder during critical moments, which can precipitate a stampede.

    How to better prevent stampedes, or at least, mitigate their risks? (Way forward)

    • Effective Crowd Management: Limit crowd size through pre-registration, schedule staggered entries, and organise queues with barriers and clear signage. Use real-time monitoring tools like CCTV and AI-based systems to manage crowd density.
    • Improved Infrastructure and Emergency Readiness: Design venues with wide pathways, multiple exits, and clear evacuation routes. Provide on-site medical facilities and train staff in crowd control, first aid, and emergency response.
    • Public Awareness and Technology Use: Educate attendees on safety protocols, and use digital tools like online ticketing and mobile alerts to prevent physical queues and guide the crowd calmly during emergencies.

    Q) The interlinking of rivers can provide viable solutions to the multi-dimensional inter-related problems of droughts, floods, and interrupted navigation. Critically examine. (UPSC CSE 2020)

    Mentor’s Comment: UPSC mains have always focused on Benefits of interlinking of rivers in (2020), and ‘Advantages and challenges of River water linking ’  in (2017).

    On December 25, 2024, Prime Minister Narendra Modi started the Ken-Betwa River Link Project to address water shortage in the Bundelkhand region, covering parts of Uttar Pradesh and Madhya Pradesh. The project includes building a dam inside the Panna Tiger Reserve, causing worries about flooding the area. It plans to connect the Ken River, believed to have extra water, with the Betwa River to help the drought-hit Bundelkhand region, which had 58% forest cover back in 1938.

    Today’s editorial talks about the challenges of the river linking project and what could the alternatives to address the water scarcity in India. This content can be used in GS mains paper III to substantiate the argument related to river water linking projects.

    _

    Let’s learn!

    Why in the News? 

    Political leaders need to understand that linking rivers causes significant environmental damage and harms rivers and deltas in the long run.

    What are the environmental consequences of river interlinking projects?

    • Ecosystem Disruption: The construction of dams and canals can lead to the submergence of critical habitats, particularly in sensitive areas like the Panna Tiger Reserve. This threatens biodiversity and disrupts local ecosystems that depend on natural water flow patterns.
    • Altered Hydrology: Diverting rivers can change the natural hydrological cycle, affecting groundwater recharge and leading to increased salinity in deltaic regions.
      • This can have dire consequences for agriculture and local livelihoods, as seen in the case of the Indus Delta.
    • Loss of Eco-services: Rivers provide essential services such as sediment transport, nutrient cycling, and habitat support for various species. By treating river water as a mere resource for transfer, these projects overlook the ecological roles rivers play in sustaining biodiversity and maintaining soil fertility.

    How do river interlinking initiatives affect local communities and socio-economic dynamics?

    • Displacement and Livelihood Loss: Projects like the Ken-Betwa initiative can displace communities living in affected areas, leading to the loss of homes and agricultural land. The Daudhan Dam alone is expected to submerge around 9,000 hectares of land, impacting numerous villages.
    • Water Access Disparities: While these projects aim to provide irrigation and drinking water to drought-prone areas, they may inadvertently prioritize certain regions over others, exacerbating existing inequalities. 
    • Economic Dependency on Infrastructure: There is a risk that local economies become overly dependent on these large projects, which may not deliver sustainable benefits. The anticipated prosperity from such initiatives may not materialize if ecological degradation occurs or if the projects do not function as intended.
    What alternatives exist to address water scarcity without compromising ecological integrity?

    • Integrated Water Resource Management (IWRM): This approach emphasizes the need for holistic management of water resources by involving local communities in decision-making processes. It focuses on sustainable practices that balance human needs with ecological health.
    • Modern Irrigation Techniques: Implementing efficient irrigation methods such as drip irrigation can significantly reduce water usage while maintaining agricultural productivity. Israel’s success in this area demonstrates the potential for technology to enhance water efficiency without large-scale environmental disruption.
    • Rainwater Harvesting and Watershed Management: Encouraging local practices like rainwater harvesting can help communities manage their own water resources sustainably. This method enhances groundwater recharge and reduces dependence on external water transfers.

    Way forward: 

    • Promote Sustainable Water Management Practices: Implement Integrated Water Resource Management (IWRM) with community participation, modern irrigation techniques like drip irrigation, and local solutions such as rainwater harvesting to reduce dependence on large-scale projects.
    • Prioritize Ecological and Social Impact Studies: Conduct comprehensive studies on the environmental and social consequences of river interlinking projects to ensure sustainable development and protect biodiversity, livelihoods, and deltaic ecosystems.
