Key Facts & Data Points
- Groundwater contribution: 62% of irrigation, 85% of rural drinking water, 50% of urban drinking water.
- Annual extraction: 245.64 billion cubic metres (BCM) – 60.47% of the national extraction rate.
- Annual recharge: 446.90 BCM (increasing since 2017).
- Groundwater monitoring stations: 43,228 (operated by CGWB).
- Artificial recharge works (Jal Sanchay Jan Bhagidari): 3,96,03,333 structures completed by Jan 2026.
Background & Context
- Groundwater constitutes ~99% of Earth’s liquid freshwater and is stored in aquifers.
- In India, it is the primary source for agriculture and a major source of drinking water.
- Governance is largely state‑centric, with the Centre providing technical and financial support.
- The sector is linked to SDG 6 (Clean Water & Sanitation), SDG 11 (Sustainable Cities), and SDG 12 (Responsible Consumption).
Drivers of Depletion
- Economic & policy incentives: Free electricity for farming and MSP‑driven cultivation of water‑intensive crops (paddy, sugarcane).
- Urbanisation: Conversion of recharge zones into impermeable surfaces; over‑pumping creates cones of depression and land subsidence.
- Climate change: Altered Southwest Monsoon patterns reduce recharge; higher temperatures increase evapotranspiration.
- Contamination: Nitrate, heavy metals (Cr, U, Pb), fluoride, and saline intrusion in coastal Gujarat.
- Legal framework: Indian Easements Act, 1882 treats groundwater as private property, hindering collective management.
- Institutional fragmentation: CGWB, CPCB, SPCBs, Ministry of Jal Shakti operate in silos.
Government Initiatives & Achievements
- Model Groundwater Bill, 2017 – adopted by 21 States/UTs.
- Jal Shakti Abhiyan – Catch the Rain (JSA:CTR) – geo‑tagging water bodies, reviving borewells.
- Jal Sanchay Jan Bhagidari (JSJB) – >39 lakh artificial recharge structures.
- National Aquifer Mapping & Management Programme (NAQUIM & NAQUIM 2.0) – Panchayat‑level aquifer data.
- Master Plan for Artificial Recharge (2020) – target of 1.42 crore structures for 185 BCM extra recharge.
- Atal Bhujal Yojana – community‑led management in 7 water‑stressed districts.
- Mission Amrit Sarovar – creation of 1‑acre ponds (≥10,000 m³) across districts.
- Monitoring – 43,228 CGWB stations for level and quality surveillance.
Strategies for Effective Management
- Water‑smart agriculture: drip & micro‑irrigation, zero‑tillage, precision farming; integrate with PMKSY.
- Institutional re‑engineering: shift from political to hydro‑geological boundaries; establish Aquifer Management Committees with legal authority.
- Digital Water Command System: IoT sensors, AI platform (e.g., ‘Bhu‑Neer’) for real‑time monitoring and predictive analytics.
- Financial restructuring: DBT for electricity subsidies, groundwater security cess for recharge fund.
- Nature‑based & advanced recharge: Managed Aquifer Recharge (MAR), solar‑desalination hybrids, bio‑char filtration, wastewater recycling, mandatory rainwater harvesting.
- Climate resilience: promote millets & pulses, water‑budget tools, community literacy.
Constitutional & Legal Provisions
- Article 21 – right to health includes access to safe water.
- Water (Prevention & Control of Pollution) Act, 1974 – limited groundwater provisions.
- Indian Easements Act, 1882 – treats groundwater as private property; reforms needed.
- Model Bill – aims to create a public trust doctrine for groundwater.
Significance for India
- Ensures food security by sustaining irrigation.
- Guarantees drinking water for rural and urban populations.
- Reduces regional disparities and mitigates climate‑induced water stress.
- Aligns with international commitments under the UN Water Convention and SDGs.
Potential UPSC Questions
- Discuss the drivers of groundwater depletion and evaluate the effectiveness of existing policy measures.
- Analyse the role of community‑led schemes like Atal Bhujal Yojana in achieving sustainable groundwater management.
- Examine the need for legal reform in groundwater governance in India.
