The total water demand in India is expected to increase by 22% and 32% by 2025 and 2050, respectively, from the present level of 680 billion cubic meters (Bm3). The industrial and domestic sectors will account for most of this excess demand(almost) 85% ).
While efficiencies in irrigation would lead to a drop in demand for water in farmlands, a small decline in food production is expected overall. Overall, water in India in future would be almost sufficient for food production.
However, the water usage pattern for food production would change, and lead to regional water crisis in many places.
Needless to say India requires investments and education in recharging groundwater, spreading water saving technologies and increasing crop productivity growth.
