India faces severe water stress with 11 out of 15 major river basins below water scarcity thresholds, necessitating urgent policy interventions in climate-proofing, water reuse, micro-irrigation, and data-driven governance.

Key points

Water Stress Indicators: 11 out of 15 major river basins in India, including Krishna and Cauvery, have annual water availability below 1,700 m3 per person, with several below the scarcity threshold of 1,000 m3 per person (CEEW data).

Urban Water Crisis: Delhi's water supply meets only 70% of its 1,250 million gallons per day demand, reflecting systemic infrastructure gaps and poor upkeep of existing systems.

Climate-Proofing Water Systems: Granular climate risk assessments for water infrastructure can prioritize investments in high-risk areas like Thane and Navsari, leveraging funds like the Urban Challenge Fund (UCF).

Circular Water Economy: Treating and reusing wastewater for non-potable purposes (e.g., construction, landscaping) could generate ₹3 lakh crore and 1,00,000 jobs by 2047 (CEEW analysis).

Micro-Irrigation Expansion: Current coverage of 20% of India's 72 million hectares irrigated potential must expand with redesigned subsidies for small farmers and crop diversification to low-water, high-value crops.

[GS3-Economy] The economic opportunity from treated wastewater and micro-irrigation aligns with sustainable agriculture and urban infrastructure development under SDG 6 (Clean Water and Sanitation).

Data Gaps in Water Management: Lack of basin-level data on withdrawals and consumption hampers efficient allocation, necessitating AI-based monitoring and smart metering akin to electricity sector reforms.

Way Forward: Implement basin-level water accounting, scale up climate-resilient infrastructure financing through UCF, and mandate treated wastewater reuse in urban planning to achieve water security by 2047.

Key terms

Water Stress Threshold

Defined by the Falkenmark Index as annual availability below 1,700 m3 per person, with scarcity below 1,000 m3. Critical for GS3 (Environment) as it frames India's resource management challenges and interstate water disputes.

Urban Challenge Fund (UCF)

A financing mechanism for urban infrastructure projects, including water supply. Exemplifies fiscal federalism (GS2) by empowering cities like Visakhapatnam to secure ₹1,501 crore for water projects.

Pradhan Mantri Krishi Sinchayee Yojana (PMKSY)

A 2015 scheme to enhance irrigation efficiency through micro-irrigation and watershed development. GS3 relevance includes its role in doubling farmers' income and climate adaptation in agriculture.

Jal Jeevan Mission

A flagship central scheme launched in 2019 to provide piped water supply to all rural households by 2024. It focuses on decentralized water management through Gram Panchayats and aligns with SDG 6. UPSC relevance lies in its governance model and challenges in implementation.
