Examine the factors responsible for depleting groundwater in India. What are the steps taken by the government to mitigate such depletion of groundwater?(Answer in 250 words)

Introduction

Groundwater is a crucial source of water for agriculture, drinking, and industry in India, accounting for nearly 60% of irrigation and about 85% of rural drinking water supply. It also supports urban water needs, industrial production, and sustains ecosystems, making it central to India’s socio-economic development. India is the largest extractor of groundwater globally, which highlights both its importance and vulnerability. However, excessive extraction, coupled with weak regulatory mechanisms and unsustainable practices, has led to alarming depletion levels in many regions. According to the Central Ground Water Board (CGWB), several blocks in states like Punjab, Haryana, Rajasthan, and Delhi fall under the “over-exploited” category, posing a serious threat to water security, food security, and ecological sustainability.

Body

Factors Responsible for Groundwater Depletion

• Over-Extraction for Agriculture: Intensive irrigation for water-intensive crops such as rice and sugarcane in semi-arid and water-stressed regions leads to rapid groundwater decline. The Green Revolution regions are particularly affected due to monocropping patterns and assured procurement policies.

• Subsidized Electricity and Pumping: Free or highly subsidized electricity encourages indiscriminate use of tube wells, resulting in over-extraction without economic checks and promoting inefficient water use.

• Rapid Urbanization and Industrialization: Expanding cities and industries increase groundwater demand while reducing natural recharge due to concretization, encroachment of water bodies, and destruction of wetlands.

• Declining Rainfall Recharge: Climate change-induced variability, erratic monsoons, and reduced infiltration limit groundwater replenishment, especially in arid and semi-arid regions, aggravating water stress.

• Poor Water Management Practices: Inefficient irrigation methods such as flood irrigation, lack of water pricing, absence of metering, and weak community-based governance exacerbate depletion.

• Legal and Institutional Gaps: Groundwater is linked to land ownership, leading to unregulated extraction, as water is treated as a private resource rather than a common pool resource, resulting in a “tragedy of the commons” scenario.

• Lack of Awareness and Behavioral Issues: Limited awareness among farmers regarding sustainable water use and absence of incentives for conservation contribute to misuse.

Government Measures to Mitigate Groundwater Depletion

• Atal Bhujal Yojana: A World Bank-supported scheme promoting community-led groundwater management, participatory water budgeting, and behavioral change in water-stressed regions.

• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY): Encourages efficient irrigation practices such as drip and sprinkler systems under the “Per Drop More Crop” component, improving water-use efficiency.

• Jal Shakti Abhiyan: Focuses on water conservation, rainwater harvesting, afforestation, and watershed development through a mission-mode approach involving multiple stakeholders.

• Regulatory Framework: CGWB guidelines regulate groundwater extraction and classify areas into safe, semi-critical, critical, and over-exploited categories to guide targeted interventions.

• Crop Diversification: Government initiatives promote less water-intensive crops like millets, pulses, and oilseeds, supported by MSP reforms and awareness campaigns.

• Digital Monitoring and Data Systems: Use of GIS-based aquifer mapping under the NAQUIM program, remote sensing, and real-time monitoring systems to improve groundwater governance.

• Water Conservation Campaigns: Programs like “Catch the Rain” and mass awareness initiatives encourage community participation in water conservation.

Conclusion

Addressing groundwater depletion requires an integrated and multi-stakeholder approach combining

efficient irrigation technologies, sustainable cropping patterns, community participation, and robust regulatory frameworks. Strengthening institutional mechanisms, rationalizing subsidies, promoting behavioral change, and leveraging technology will be essential to ensure long-term water security, climate resilience, and sustainable agricultural growth in India.
