DYNAMIC GROUNDWATER RESOURCES ASSESSMENT, 2025
1. At a Glance
- Annual nation-wide stocktake of replenishable groundwater carried out by Central Ground Water Board (CGWB) under the Ministry of Jal Shakti jointly with State/UT groundwater departments [S1].
- Reports four headline numbers: Annual Recharge, Extractable Resource, Annual Extraction, and Stage of Extraction (SoE), plus categorisation of every block/taluk/mandal as Safe / Semi-Critical / Critical / Over-Exploited [S1][S2].
- 2025 edition shows continued improvement: SoE 60.63%, share of "Safe" units up to 73.14% from 62.6% in 2017 — a recurring Prelims/Mains data point on water security [S2].
2. Why in the News
- Report released on 29 January 2026 by the Ministry of Jal Shakti for assessment year 2025 [S1].
- Marks the first national assessment showing over-exploited blocks falling below 11% (730 units), continuing the downtrend from 2017 [S2].
3. Background & Evolution
- Assessment first done in 1980; periodic exercises in 1995, 2004, 2009, 2011, 2013 [S3 inferred from PIB history].
- GEC-1997 (Ground Water Estimation Committee) norms used till 2013; replaced by GEC-2015 methodology, applied from the 2017 assessment onwards — introduces aquifer-wise computation of both Dynamic (replenishable) and In-storage (static) resources [S2].
- Since 2022 the exercise is conducted annually using the web-based "INDIA-GWRA" portal [S1].
4. Core Static Facts
- Nodal body: Central Ground Water Board (CGWB), under Department of Water Resources, RD & GR, Ministry of Jal Shakti [S1].
- Methodology: GEC-2015 (aquifer-wise; separates command/non-command, recharge/discharge season) [S2].
- Assessment Unit (AU) = Block / Taluk / Mandal / Firka.
- Total AUs (2025): 6,762 [S2].
- 2025 headline numbers [S1][S2]:
- Annual Ground Water Recharge: 448.52 BCM
- Annual Extractable Resource: 407.75 BCM
- Annual Extraction: 247.22 BCM
- Stage of Extraction (SoE) = 60.63%
- Categorisation thresholds (SoE) [S2]:
- Safe: ≤ 70%
- Semi-Critical: 70–90%
- Critical: 90–100%
- Over-Exploited: > 100%
- 2025 AU categorisation [S2]: Safe 4,946 (73.14%), Semi-Critical 758 (11.21%), Critical 201 (2.97%), Over-Exploited 730 (10.80%).
5. Multi-Dimensional Analysis
- Environmental: India remains the world's largest groundwater user; SoE of 60.63% means ~40% buffer nationally but masks acute regional stress in Punjab, Haryana, Rajasthan, Delhi — over-exploited belts in NW India [S2].
- Economic / Agricultural: Irrigation accounts for the dominant share of the 247.22 BCM extraction; the resource underwrites foodgrain output of the NW & southern peninsula [S1].
- Administrative / Federal: Water is a State subject (Entry 17, List II); CGWB assessment is advisory — categorisation triggers state-level regulation, NOC regimes & MGNREGS-linked recharge works [S1].
- Technological: Use of GIS, remote sensing & INDIA-GWRA portal for aquifer-level estimation under GEC-2015 [S2].
- Governance: Improvement (Safe units 62.6% → 73.14% between 2017-2025) attributed to Atal Bhujal Yojana, PMKSY, Jal Shakti Abhiyan: Catch the Rain, MGNREGS water-structures [S2].
6. Recent Developments (last 12-18 months)
- 2025 Report released 29 Jan 2026 — Annual Recharge 448.52 BCM; SoE 60.63%; 730 over-exploited blocks [S1].
- 2024 Report released earlier — SoE then ~60.4%; this year shows marginal further improvement [S2].
- Continued thrust under Atal Bhujal Yojana (2020-25) in 7 states (Gujarat, Haryana, Karnataka, MP, Maharashtra, Rajasthan, UP) for participatory groundwater management [S2].
7. Prelims Hooks
- Assessment year 2025 published January 2026 by CGWB / Ministry of Jal Shakti [S1].
- Annual Recharge: 448.52 BCM; Extractable: 407.75 BCM; Extraction: 247.22 BCM [S1].
- Stage of Extraction = 60.63% for India (2025) [S1].
- Total Assessment Units: 6,762; Over-exploited: 730 (10.80%) [S2].
- Safe category share rose from 62.6% (2017) → 73.14% (2025) [S2].
- Over-exploited share fell from 17.2% (2017) → 10.8% (2025) [S2].
- Methodology in use: GEC-2015 (replaced GEC-1997) [S2].
- Categorisation cut-offs: 70 / 90 / 100 percent of extractable resource [S2].
- SoE = Annual Extraction ÷ Annual Extractable Resource (NOT total recharge) [S1].
- CGWB falls under Dept. of Water Resources, RD & GR, Ministry of Jal Shakti (not MoEFCC) [S1].
- Water is in State List, Entry 17; inter-state rivers in Union List, Entry 56.
8. Mains Relevance
- GS-I: Distribution of natural resources — water; geographical features.
- GS-III: Conservation, environment & disaster management; Agriculture (irrigation); Food security.
- Probable stems: 1. "Despite a falling stage of groundwater extraction at the national level, India faces acute aquifer stress in pockets. Discuss with reference to Dynamic Groundwater Resources Assessment, 2025." 2. "Evaluate the GEC-2015 methodology in capturing aquifer-level groundwater dynamics in India." 3. "Examine the contribution of Atal Bhujal Yojana and MGNREGS to the improvement in 'Safe' category assessment units between 2017 and 2025."

10. Common Errors / Trap Areas
- SoE denominator is Extractable (407.75 BCM), not Total Recharge (448.52 BCM) — easy MCQ trap.
- CGWB sits under Ministry of Jal Shakti, not MoEFCC or MoA.
- CGWB ≠ CGWA — Board does assessment & R&D; Authority regulates extraction under EPA 1986.
- "Over-exploited" threshold is >100% SoE, not >90%.
- Assessment is annual since 2022; prior cycles were biennial/multi-year (don't say "decadal").
- Atal Bhujal Yojana covers only 7 states, not all-India.
