Item Detail
Nodal Ministry Ministry of Jal Shakti (Dept. of Water Resources, River Development & Ganga Rejuvenation; Dept. of Drinking Water & Sanitation) [S3][S4]
Atal Bhujal Yojana ₹6,000 crore outlay; 2020–2026 (6 years); World Bank-supported; covers 7 states, 80 districts, 229 blocks [S4]
Jal Jeevan Mission Launched Aug 2019; goal — Har Ghar Jal (tap water to every rural household) [S4]
PMKSY 2015; irrigation infrastructure + water-use efficiency ("more crop per drop")
Water stress threshold <1,700 m³ per capita/year = "water stressed"; <1,000 m³ = "water scarce" (internationally accepted Falkenmark-type indicator) [S1]
India basin stress 11/15 major basins water-stressed; Krishna, Cauvery, Mahi, Tapi below scarcity line [S1]
Delhi case data Demand 1,250 MGD; supply ~70% of demand (mid-2026) [S1]
Monsoon deficit (June 2026) >40% below normal, nationally [S1]
Global Water Bankruptcy Report UNU-INWEH; author K. Madani; released 20 Jan 2026; ~4 billion people face severe water scarcity ≥1 month/year; ~75% of global population lives in water-insecure countries [S2]
Monitoring portal Atal Jal Portal & mobile app — public disclosure of Water Security Plans [S4]

5. Multi-Dimensional Analysis

Environmental - Aquifer depletion beyond safe yield limits and closed/polluted river basins with no outflow to sea are flagged globally by UNU-INWEH, mirrored in Indian basins like Krishna and Cauvery [S1][S2]. - Climate variability (40% monsoon deficit in a single month) shows rainfall dependency is no longer a reliable buffer for water security [S1].

Economic - Water stress threatens agriculture (irrigation-dependent basins), urban economies (Bengaluru's tech economy), and increases costs of tanker-based/private water supply substitution. - Infrastructure gaps — poor upkeep of existing assets and inadequate wastewater treatment — raise the marginal cost of "new" water versus recycled/treated water [S1].

Social - Urban water stress disproportionately burdens low-income households lacking piped connections, forcing reliance on informal tankers. - JJM's rural focus (Har Ghar Jal) targets equity in access but supply-side stress (as in Delhi) shows urban equity gaps persist [S4].

Administrative/Governance - Water is a State subject under the Constitution (Entry 17, State List; Entry 56, Union List for inter-state rivers), creating federal coordination challenges for basin-level management. - Atal Bhujal Yojana's community-led, demand-side model is an administrative innovation — devolving groundwater management to Gram Panchayats with public data disclosure via the Atal Jal Portal [S4].

Scientific/Technological - CEEW's basin-level water-stress mapping (11/15 basins) exemplifies data-driven diagnostic tools underpinning policy [S1]. - UNU-INWEH's "water bankruptcy" is a newly formalized scientific concept — basins/aquifers unable to return to historical hydrological norms [S2].

Geopolitical/Strategic - Report urges leveraging the 2026 and 2028 UN Water Conferences and the 2028 end of the Water Action Decade to reset global water governance — relevant to India's positioning in multilateral water diplomacy [S2].
