Examine the factors responsible for depleting groundwater in India. What are the steps taken by the government to mitigate such depletion of groundwater?

According to the UN World Water Development Report, India is the largest extractor of groundwater in the world, accounting for roughly 25% of global extraction. NITI Aayog’s Composite Water Management Index highlights a severe crisis, noting that over 50% of India's groundwater wells are witnessing a decline in water levels, posing a severe threat to the country's agrarian economy, food security, and urban sustainability.

Factors Responsible for Depleting Groundwater in India

1. Agricultural and Agrarian Factors:

• Skewed Cropping Patterns: The legacy of the Green Revolution has led to the widespread cultivation of water-intensive crops like paddy and sugarcane in semi-arid and water-stressed regions (e.g., Punjab, Haryana, and Maharashtra). Agriculture consumes nearly 89% of India's groundwater.
• Minimum Support Price (MSP) Bias: Open-ended procurement and assured MSP for wheat and paddy inherently disincentivize farmers from shifting to less water-intensive, climate-resilient crops like millets and pulses.

2. Policy and Economic Factors:

• The Water-Energy Nexus: Heavily subsidized or free electricity provided to the agricultural sector encourages farmers to run high-capacity tubewells continuously, leading to the rampant over-exploitation of deep aquifers.
• Legislative Loopholes: Under the Indian Easements Act, 1882, groundwater rights are tied to land ownership. This legally treats groundwater as a private commodity rather than a common-pool public resource, rendering its extraction highly unregulated.

3. Urbanization and Infrastructure:

• Loss of Recharge Zones: Unplanned urbanization, rapid concretization, and the encroachment of wetlands and natural lakes have drastically reduced the surface area available for natural rainwater percolation.
• Unregulated Industrial Extraction: Industries often rely heavily on groundwater for manufacturing processes without implementing adequate water recycling protocols.

4. Climatic and Environmental Factors:

• Erratic Monsoons: Climate change has led to spatial and temporal variations in rainfall. Fewer rainy days with higher intensity runoff reduce the time available for water to percolate and recharge aquifers.

Steps Taken by the Government to Mitigate Groundwater Depletion

To address this systemic crisis, the government has adopted a multi-pronged approach encompassing supply-side augmentation, demand-side management, and regulatory frameworks:

1. Institutional and Participatory Initiatives:

• Atal Bhujal Yojana (ABHY): A ₹6,000 crore World Bank-funded central sector scheme implemented in seven water-stressed states. It uniquely focuses on demand-side management and behavioral change through community-led Water Security Plans at the Gram Panchayat level.
• Jal Shakti Abhiyan (JSA): Launched as a mass movement with the theme "Catch the Rain, where it falls, when it falls", focusing on rainwater harvesting, watershed development, afforestation, and the rejuvenation of traditional water bodies.

2. Agricultural and Technological Interventions:

• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY): Through its 'Per Drop More Crop' component, the government is heavily subsidizing micro-irrigation techniques (drip and sprinkler systems) to drastically improve agricultural water-use efficiency.
• Promotion of Nutri-Cereals (Shree Anna): The National Millet Mission and the declaration of 2023 as the International Year of Millets aim to shift dietary and cropping patterns toward these drought-resistant, low-water crops.
• PM-KUSUM Scheme: While primarily an energy scheme, enabling farmers to set up grid-connected solar pumps allows them to sell surplus power back to the grid. This creates an economic incentive to conserve electricity and, by extension, groundwater.

3. Regulatory and Infrastructure Measures:

• CGWA Guidelines (2020): The Central Ground Water Authority introduced stringent guidelines making No Objection Certificates (NOC) mandatory for new and existing industries, infrastructure projects, and mining projects, accompanied by the levy of an Environmental Compensation charge for illegal extraction.
• Master Plan for Artificial Recharge (2020): Envisages the construction of millions of artificial recharge structures across the country to harness surplus monsoon runoff into groundwater aquifers.
• Amrit Sarovar Mission: Aimed at constructing or rejuvenating 75 water bodies in every district to enhance surface water availability and natural groundwater recharge.

Way Forward

While government initiatives have set the foundation, arresting groundwater depletion requires a paradigm shift.

• National Water Commission: The recommendations of the Mihir Shah Committee to merge the Central Water Commission (CWC) and the Central Ground Water Board (CGWB) into a unified National Water Commission must be expedited to ensure integrated water resource management.
• Legal Reforms: Decoupling water rights from land rights and enacting a comprehensive National Groundwater Management Law based on the Public Trust Doctrine is essential.
• Water Accounting and Pricing: Implementing smart water metering and direct benefit transfers (DBT) for electricity savings (e.g., Punjab’s Paani Bachao, Paisa Kamao scheme) can financially incentivize conservation.

Groundwater is a finite, critical resource. Moving from a mindset of 'supply augmentation' to strict 'demand-side management' and fostering a circular water economy (Reduce, Recycle, Reuse) is imperative to achieve Sustainable Development Goal 6 (Clean Water and Sanitation) and secure India's ecological and economic future.
