India accounts for roughly 18% of the world’s population but holds only 4% of global renewable freshwater resources. Groundwater serves as the primary water source for domestic, agricultural, and industrial uses, providing over 60% of irrigation and 85% of rural drinking water, leading to declining water tables across major agricultural regions.

Factors Responsible for Groundwater Depletion

• Agrarian Over-Extraction of Water-Intensive Crops: Heavily subsidized or free agricultural power policies incentivize excessive extraction via deep tube-wells, encouraging water-intensive crops like summer paddy and sugarcane in water-stressed belts of Punjab, Haryana, and western Maharashtra.
• Urbanization and Loss of Natural Recharge: Paving urban surfaces with concrete and encroaching upon catchment wetlands limits natural stormwater infiltration into local aquifers.
• Industrial Overuse Without Treatment: Industrial units often extract groundwater without setting up effective closed-loop wastewater recycling or artificial recharge systems.
• Deforestation and Catchment Degradation: Clearing forests on hill slopes accelerates surface runoff and reduces baseflow infiltration needed to replenish regional groundwater reserves.
• Climate Variability: Increasingly erratic monsoons, recurring dry spells, and higher summer temperatures reduce natural recharge rates while raising irrigation requirements.
• Inefficient Irrigation Practices: Widespread use of flood irrigation techniques causes water loss through evaporation and deep percolation, yielding low water-use efficiency.

Government Steps to Mitigate Groundwater Depletion

1. Policy and Statutory Interventions

• Atal Bhujal Yojana (ABHY): A ₹6,000 crore community-led program supported by the World Bank targeting 8,220 over-exploited Gram Panchayats across seven states, linking financial incentives with behavioral water-budgeting.
• Jal Shakti Abhiyan (Catch the Rain): A nationwide monsoon campaign focusing on desilting traditional stepwells (baolis), rejuvenating village tanks, and constructing rooftop rainwater harvesting structures.
• Mandatory CGWA Regulation: The Central Ground Water Authority regulates commercial and industrial extraction, mandating digital flowmeters, environmental compensation, and artificial recharge certification.

2. Infrastructure and Technology Measures

• Per Drop More Crop (PDMC under PMKSY): Subsidizes drip and sprinkler irrigation installations, improving on-farm water-use efficiency.
• Aquifer Mapping (NAQUIM 2.0): The Central Ground Water Board uses 3D hydrogeological mapping and heliborne geophysical surveys to map aquifer boundaries and identify recharge zones.
• Mission Amrit Sarovar: Constructed and rejuvenated over 60,000 community ponds to improve local groundwater recharge and provide village water storage.

3. Demand-Side Management

• Crop diversification programs encourage farmers to shift from paddy to pulses, oilseeds, and millets (Shree Anna), supported by minimum support price incentives.

Reversing groundwater depletion requires combining regulatory oversight with community-led water budgeting and micro-irrigation to ensure sustainable water security.
