Building water security in a drying India

Question (10 marks, ~150 words):

India's water insecurity cannot be solved by supply-side projects alone. Critically examine, suggesting a way forward.

State the 4%/18% mismatch and 11/15 stressed basins. Argue demand-side (80% agri, micro-irrigation 20%), reuse (Rs 3 lakh cr by 2047), data/metering. Balance with supply augmentation. Way forward: basin-level, data-driven integrated management.
