India's Water Stress
Monsoon Dependence and Reservoir Management
India receives nearly 75% of its annual precipitation during the June-September southwest monsoon. The remaining months depend on stored surface water (reservoirs), groundwater, and diminishing snowmelt from the Himalayas. India has ~5,000 large dams, with the 130-166 monitored reservoirs providing irrigation (roughly 60% of their use), hydropower, and drinking water. A below-normal monsoon year — or a delayed winter rainfall (northeast monsoon failure) — directly reduces reservoir inflows. India's per-capita water availability has declined from ~5,177 cubic metres/year in 1951 to below 1,486 cubic metres/year (2020), crossing the "water stress" threshold of 1,700 cubic metres/person/year.
- Monsoon season: June 1 to September 30 (southwest monsoon, Bay of Bengal and Arabian Sea branches)
- India's average annual rainfall: ~1,170 mm, but highly variable geographically
- India's per capita water availability 2020: ~1,486 cubic metres/year (below 1,700 threshold = "water stressed")
- National Water Policy 2012: emphasises river basin as planning unit; advocates demand-side management
- Jal Jeevan Mission (2019): targets tap water to all rural households by 2024 (extended to 2026)
- Jal Shakti Abhiyan: catchment area treatment, waterbody restoration, recharge structures
