Indian cities need to rethink their water future

📌 Summary:

• Context: a heatwave-aggravated water shortage — driven by a groundwater crisis and falling reservoir levels — has hit metros including Delhi, Mumbai, Bengaluru and Chennai
• Core argument: climate change alone cannot explain the scarcity; Indian cities are living "beyond their hydrological means" and the failure is structural and governance-driven
• Causal chain / drivers: (1) Dilapidated distribution networks + inadequate metering + poor municipal governance → high water losses (2) Untreated wastewater + under-harvested rainwater → scarce resources wasted (3) Decades of supply-side focus with neglect of demand-side management → overexploitation of aquifers
• Data & precedents: NITI Aayog's Composite Water Management Index (CWMI, 2018) warned of crisis; Jal Shakti Ministry's Dynamic Groundwater Resources Assessment flags aquifer over-extraction; Mihir Shah Committee (2016) flagged the supply-side bias and lack of institutional innovation
• India's vulnerability: cities flooded in the monsoon yet parched in summer; over-extraction by the well-heeled
• Solutions proposed: demand-side management; scientific household/industrial water-use audits; scale up nature-based solutions (lake restoration in Mumbai, Bengaluru); a concerted policy like China's Sponge City programme (permeable pavements, green infrastructure); build on the Atal Bhujal Yojana

🎯 UPSC Relevance: GS1/GS3 — urbanisation and water resources, sustainable development, municipal governance

📝 Prelims Facts:

• NITI Aayog Composite Water Management Index (CWMI), 2018
• Mihir Shah Committee (2016) — demand-side management
• Atal Bhujal Yojana; China's Sponge City programme

🔑 Key Term: Demand-side water management — managing consumption and efficiency rather than only augmenting supply.
