What Happened

Telangana's Dynamic Groundwater Resources Assessment for 2025 has been officially released, confirming escalating groundwater depletion across the state.
The assessment process for 2026 has formally commenced, following the methodology jointly developed by the Central Ground Water Board (CGWB) and respective state agencies.
Water management experts have argued against imposing a blanket ban on paddy cultivation as the primary solution to groundwater stress, instead advocating for increased water harvesting and comprehensive demand-side management.
Telangana's existing programmes — Mission Kakatiya (tank restoration), Mission Bhagiratha (drinking water supply), KLIP (water transfer), and Haritha Haram (afforestation) — are cited as the preferred multi-pronged framework.
In severely affected districts (formerly Nalgonda region), over 4.2 lakh acres of paddy withered and groundwater levels fell 3–5 metres in 2023–24, illustrating the urgency of the situation.

Groundwater Assessment in India — CGWB Methodology and the Dynamic GWR Report

Periodic assessment of India's dynamic groundwater resources is jointly carried out by the Central Ground Water Board (CGWB) under the Ministry of Jal Shakti and state/UT groundwater agencies. The most recent national report — Dynamic Ground Water Resources of India, 2025 — was released by the Ministry of Jal Shakti in December 2025. It uses the IN-GRES (INdia-Groundwater Resource Estimation System) platform, developed with IIT Hyderabad, to standardise data collection and computation across all assessment units (blocks/tehsils/mandals).

Total Annual Groundwater Recharge (2025): 448.52 Billion Cubic Metres (BCM).
Annual Extractable Groundwater Resources: 407.75 BCM.
Annual Groundwater Extraction (2025): 247.22 BCM.
Stage of Extraction (SoE) nationally: 60.63%.
Classification: Safe (<70% SoE), Semi-critical (70–90%), Critical (90–100%), Over-Exploited (>100%).
Safe assessment units improved from 62.6% (2017) to 73.14% (2025); over-exploited units fell from 17.2% to 10.8%.

Connection to this news: Telangana's 2025 assessment follows this national methodology. The state's release of its own report is part of the annual cycle, and the commencement of the 2026 assessment signals a regular monitoring cadence critical for evidence-based agricultural policy reform.

Groundwater Depletion and Paddy Cultivation — The Agricultural Nexus

Paddy (rice) is among the most water-intensive crops, requiring 1,200–2,000 litres of water per kilogram of output depending on cultivation method and climate. Telangana's rapid expansion of paddy cultivation, partly incentivised by assured procurement, has been identified as a key driver of groundwater depletion, particularly in the state's hard-rock aquifer zones. The debate between restricting water-intensive crops versus investing in water harvesting infrastructure mirrors a broader national tension between food security, farmer income, and natural resource sustainability.

Paddy requires approximately 1,400 litres of water per kg (compared to ~500 litres for millets).
Hard-rock aquifer regions (dominant in peninsular India including Telangana) have limited recharge capacity.
India uses approximately 89% of its freshwater for agriculture (highest sectoral share globally).
MSP-backed procurement of rice incentivises paddy cultivation even in water-scarce regions.

Connection to this news: Experts cited in Telangana's policy discourse argue that banning paddy shifts the burden onto farmers without addressing the structural supply-side deficit; more effective is augmenting recharge through watershed development, tank restoration, and check dams.

Mission Kakatiya — Tank Restoration and Groundwater Recharge

Mission Kakatiya is a Telangana state government programme aimed at restoring and rejuvenating the state's historic network of minor irrigation tanks, which were integral to traditional water management under the Kakatiya dynasty. The programme involves desilting tank beds, strengthening bunds, repairing sluices and weirs, and restoring feeder channels. Restored tanks increase surface water storage, reduce runoff, and enhance groundwater recharge — directly addressing the supply side of the groundwater equation without restricting agricultural choices.

Phase I target: restoration of 46,531 tanks across Telangana.
Desilting tanks increases their storage capacity and irrigated command area.
Restored tanks function as decentralised recharge structures for hard-rock aquifers.
The programme has been cited as a model for watershed-based water conservation nationally.

Connection to this news: Mission Kakatiya exemplifies the "harvest more water" approach that experts prefer over paddy bans — augmenting supply through decentralised storage and recharge rather than restricting cropping patterns.

Demand-Side Management in Water Policy — Pricing, Crop Diversification, and Micro-Irrigation

Demand-side management (DSM) for agricultural water involves price signals, crop diversification incentives, and water-use efficiency technologies to reduce per-unit crop water consumption. The Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) promotes micro-irrigation (drip and sprinkler systems) under its "Har Khet Ko Pani, More Crop Per Drop" framework. Crop diversification away from water-intensive paddy and sugarcane toward pulses, oilseeds, and millets is a key recommendation of successive National Water Policy documents (2012, and the draft 2019 revision).

PMKSY's micro-irrigation fund: ₹5,000 crore corpus at NABARD.
Drip irrigation can reduce water use by 30–50% compared to flood irrigation in paddy.
National Water Policy 2012 recognises groundwater as a common resource requiring public regulation.
The draft National Water Policy (under revision) emphasises aquifer-level management and community participation.

Connection to this news: The debate in Telangana directly reflects the tension identified in national water policy between supply-side augmentation and demand-side regulation — both of which are necessary for sustainable groundwater management, and both of which are tested concepts relevant to UPSC Mains.
