Indian cities need to rethink their water future

📌 Summary:

• Context: A heat wave has been aggravated by severe urban water shortage driven by a groundwater crisis and falling reservoir levels, hitting metros such as Delhi, Mumbai, Bengaluru and Chennai
• Core argument: Climate change alone cannot explain the scarcity; Indian cities are living beyond their hydrological means and treat each crisis as an isolated event rather than fixing structural causes
• Early warnings ignored: NITI Aayog's Composite Water Management Index (CWMI, 2018) warned of a dire situation; the Jal Shakti Ministry's Dynamic Groundwater Resources Assessment has flagged over-extraction of aquifers
• Causal chain of urban inefficiency: dilapidated distribution networks (high leakage), inadequate metering, poor municipal governance, untreated wastewater, and underharvesting of rainwater all prevent optimum use of scarce water
• Policy diagnosis: the Mihir Shah Committee (2016) noted Indian water policy focused on augmenting supply while neglecting demand-side management; this aided food security but left a gap in institutional innovation
• Solutions urged: demand-side management with scientific analysis of household and industrial use to curb overexploitation by the well-heeled; scale up nature-based solutions (lake restoration in Mumbai, Bengaluru) and adopt a sponge-city style policy (permeable pavements, green infrastructure) like China to retain rainwater
• Programmes cited: Atal Bhujal Yojana as an early step toward efficient water use in agriculture

🎯 UPSC Relevance: GS1/GS3 - urbanisation and urban governance, water resource management, demand-side management, and sustainable city planning.

📝 Prelims Facts:

• Composite Water Management Index (CWMI) is a NITI Aayog initiative (2018)
• Atal Bhujal Yojana promotes efficient groundwater use, especially in agriculture
• Mihir Shah Committee (2016) reviewed water management; the Dynamic Groundwater Resources Assessment is by the Jal Shakti Ministry
• Sponge City is a Chinese urban water-retention model

🔑 Key Term: Demand-side management - reducing and rationalising water consumption (metering, pricing, efficiency) rather than only augmenting supply.
