2025-26 Dynamic Groundwater Assessment
- The dynamic groundwater assessment in India is conducted jointly by the Central Ground Water Board (CGWB) and the State/UT Ground Water Departments and the report is released under the authority of the Ministry of Jal Shakti.
- As per the 2025-26 Dynamic Groundwater Assessment.
- National SoE (Stage of Groundwater Extraction) is 60.63% which is safe , but 730 of 6,762 units (10.8%) are over-exploited, mostly in the North-West, West and South.
- Punjab is the worst case: it draws 26.32 BCM against 17.29 BCM extractable, an SoE of 152%. So Punjab uses about 52% more than it can sustainably withdraw.
- Irrigation uses 24.95 BCM of this.
- Farm practices drive the crisis: water-hungry crops, free power, MSP bias, flood irrigation and a tube well race.
- Degradation is about quality too: nitrate, fluoride, arsenic and uranium contamination.
Important concepts
- Aquifer: An underground layer that stores and releases water.
- Alluvial aquifers (Punjab, Haryana) recharge easily; hard-rock aquifers (Peninsular India) store little.
- Recharge: Water that seeps into aquifers from rain, canals, ponds and irrigation. India: 448.52 BCM a year.
- Stage of Groundwater Extraction (SoE): Extraction ÷ extractable resource × 100.
- Categories: Safe (up to 70%), Semi-critical (70–90%), Critical (90–100%), Over-exploited (above 100%).
- Over-exploitation: Drawing more than the aquifer refills each year, which amounts to mining water.
- Groundwater depletion: A long-term fall in stored groundwater.
- Groundwater stress: Pressure on supply to meet the demand, even if water is not absent. India measures it by SoE.
- Groundwater scarcity: Water not available or not usable when needed.
- Physical scarcity: aquifers drying, as in Bundelkhand or Bengaluru’s borewells in 2024.
- Economic scarcity: water exists deeper but the poor cannot afford to reach it, as with Punjab’s small farmers buying water.
- Falkenmark index (per person per year): below 1,700 m³ is stress, below 1,000 m³ scarcity, below 500 m³ absolute scarcity. India’s availability is about 1,486 m³ (2021 estimate), so India is water-stressed.
- Groundwater degradation: Loss of quality. Nitrate (Rajasthan, Tamil Nadu, Maharashtra), fluoride (Haryana, Karnataka), arsenic (Ganga–Brahmaputra plains), uranium (Punjab’s Malwa belt).
- Groundwater drought: Water levels stay low even after the monsoon because the aquifer did not refill.
- Virtual water: Water embedded in traded goods. Punjab’s rice and wheat sent to the central pool carry its aquifer out of the State.
How farming practices affect groundwater adversely?
- Wrong crops in wrong places: Paddy needs roughly 3,000–5,000 litres per kg yet is grown in semi-arid Punjab and Haryana; sugarcane dominates drought-prone Marathwada.
- Free or flat-rate power: Free in Punjab since 1997. When pumping costs nothing extra, no one saves water.
- MSP and assured procurement: Only wheat and paddy are reliably bought, which locks farmers into the rice-wheat cycle.
- Flood irrigation: Efficiency of about 35–40%, against about 90% for drip.
- Tube well race: Punjab has about 14 lakh tube wells. Deep submersible pumps replaced shallow ones, and each farmer pumps harder to keep up: a tragedy of the commons (Garrett Hardin, 1968).
- Tushaar Shah calls India’s groundwater economy an ‘atomistic’ or ‘anarchic’ system: millions of private pumps with no collective control.
- Loss of recharge structures: Ponds, tanks and johads encroached or silted; canals neglected.
- Chemical overuse: Excess urea leaches nitrate into aquifers.
- Soil damage: Compaction, loss of organic matter and stubble burning reduce rain soaking into the ground.
- Drainage failure: Waterlogging and salinity in SW Punjab (Fazilka, Muktsar), the opposite problem.
Present Legal and institutional framework
- Water is a State subject (Entry 17, List II), subject to Entry 56, List I.
- Indian Easements Act, 1882: The landowner can draw the groundwater beneath his land. There is no legal cap on private pumping.
- CGWA under Section 3(3) of the Environment (Protection) Act, 1986; its 2020 guidelines on groundwater use exempt agriculture.
- Model Groundwater Bill, 2016 (Mihir Shah Committee): groundwater as a common resource held in public trust.
- Judgments: Subhash Kumar v. State of Bihar (1991) read clean water into Article 21.
Challenges before the government
- Subsidy politics: Free power and MSP are hard to touch; metering meets farmer resistance.
- Legal gap: Land-linked groundwater rights leave no cap on private pumping.
- Federal limits: Few States have adopted the Model Bill; the CGWA does not regulate farm use.
- Weak markets for other crops: Maize, pulses and millets lack assured prices, storage and processing.
- Small landholdings: 86% of farmers are small or marginal (Agriculture Census 2015-16); drip costs too much for them.
- Food security: Punjab and Haryana feed the central pool, so a sudden shift could hurt the PDS.
- Data gaps: Sparse observation wells and few metered tube wells.
- Perverse effects: PM-KUSUM solar pumps make pumping free unless linked to buy-back of surplus power.
- Collective action and climate change: Shared aquifer, separate decisions; erratic monsoons raise irrigation demand.
Way ahead
- The Mihir Shah Committee (2016) recommended:
- Merging the CWC and CGWB into a National Water Commission.
- Treating groundwater as a common-pool resource held in public trust.
- Participatory aquifer mapping and management, with farmers as stakeholders.
- Shifting from supply-side to demand-side management.
- Procuring water-saving crops to support diversification.
- Stronger groundwater regulation, taken forward in the Model Groundwater Bill (2016).
- Price reform: Meter power with a free quota and pay for units saved (Pani Bachao Paisa Kamao). Separate farm feeders (Gujarat’s Jyotigram, 2003). Solar power buy-back (Dhundi solar cooperative, Gujarat).
- Monetary incentives : Pani Bachao Paisa Kamao scheme in Punjab incentivises farmers saving per kilowatt hours below the threshold.
- Crop shift: Per-acre incentives to leave paddy (Haryana’s Mera Pani Meri Virasat). MSP and procurement for maize, pulses, cotton and millets. Direct Seeded Rice and alternate wetting and drying.
- Efficiency: Micro-irrigation under PMKSY ‘Per Drop More Crop’, with group drip for small farmers.
- Recharge: Jal Shakti Abhiyan ‘Catch the Rain’, Mission Amrit Sarovar, MGNREGA water works, canal-based managed aquifer recharge.
- Legal reform: Adopt the Model Groundwater Bill; regulate by aquifer rather than land; bring Punjab into Atal Bhujal Yojana or a State version.
- Community management: Andhra Pradesh Farmer Managed Groundwater Systems (APFAMGS); Hiware Bazar, Maharashtra.
- Target the cultivator: Route benefits to tenants and smallholders, not landowners or pump owners.
