Building water security in a rapidly drying India

The article highlights the growing crisis of water scarcity and depleting aquifers in India, exacerbated by climate change and erratic monsoons. The Council on Energy, Environment and Water (CEEW) notes that 11 out of 15 major river basins are experiencing water stress, meaning their annual per capita availability is below 1,700 cubic meters. Basins like Krishna and Cauvery have fallen below the water scarcity threshold of 1,000 cubic meters per person. This scenario reflects a critical environmental challenge, requiring a shift towards a circular water economy. This involves treating and reusing wastewater for non-potable purposes, reducing reliance on freshwater extraction. The United Nations University Institute for Water, Environment and Health (UNU-INWEH) warns of 'global water bankruptcy', emphasizing the need to integrate climate risk assessments into urban planning to protect vulnerable infrastructure from floods and changing precipitation patterns.

Addressing India's water crisis requires robust governance reforms and institutional capacity building, particularly at the local level. While national schemes like the Jal Jeevan Mission and Pradhan Mantri Krishi Sinchayee Yojana aim to improve infrastructure, significant gaps remain in maintenance, pollution control, and cost recovery. The article emphasizes the crucial role of urban local bodies (ULBs) and panchayats in implementing climate-proof water systems and city-level reuse plans. However, these bodies often face financial constraints. Leveraging mechanisms like the Urban Challenge Fund can provide vital financing for risk assessments and infrastructure upgrades. Furthermore, the lack of comprehensive, basin-level data on water withdrawal and consumption hinders effective decision-making and allocation. Implementing AI-based monitoring and smart metering, similar to the rollout in the electricity sector, is essential for identifying losses, ensuring equitable distribution, and preventing 'free riding' by over-extracting users.

Water is framed as a critical economic resource, essential for livelihoods and agricultural productivity. The current agricultural water use, characterized by inefficient flood irrigation, needs a structural shift towards micro-irrigation (drip and sprinkler systems). To achieve this, the article suggests redesigning subsidies to better target small and marginal farmers, by lowering the base unit size for eligibility. Additionally, encouraging a transition to low-water, high-value crops (like horticulture and oilseeds) is vital for cost recovery and sustainable agriculture. The economic viability of these shifts must be supported by strengthened risk mitigation tools, such as the Pradhan Mantri Fasal Bima Yojana. Beyond agriculture, the transition to a circular water economy presents significant economic opportunities. The sale of treated wastewater can generate revenue for municipalities, potentially reaching ₹3 lakh crore and creating substantial employment by 2047, highlighting the economic potential of sustainable water management.
