What are the primary drivers of freshwater scarcity in megacities like Bangalore and Hyderabad? Suggest comprehensive solutions that address both supply and demand aspects of urban water management.

India supports 18% of world population with 3% of land surface and 4% of the world's water resources, creating significant demand-supply mismatches. Primary drivers of freshwater scarcity: 1) Scarcity of freshwater availability due to limited reservoir and burgeoning population. eg: Nega cities => 100 lore + population. 2) Skewed precipitation pattern due to global warming and climate change => eg: Drought in Bangalore living rainy period. 3) Increased runoff and lack of natural storage for rainwater. eg: According to NASA, with 1% rice in impervious surfaces, penetration declines by 88%.

over towers, building parks etc. 4) Resolving inter-state water disputes by basin level planning. eg: Kaveri dispute between Chennai n Bangalore. 5) Comprehensive capacity building of municipals to identify, assess, manage and distribute water. B) Demand-side: 1) Water cess should be charged after free allocation of minimum quota. 2) Localized management of residential complexes => incentives on generation of excess supply through drain water harvesting system. 3) Unit monitoring of wastage of freshwater => fines and penalised. 4) Water policies should be taught at school level to manage and conserve water. 5) Cultivation of awareness regarding requiring of water. Therefore, water is a key precious resource, and negatives need to amp up their efforts to ensure SDG-8
