Why rice irrigation matters: a look at India’s 2026 water crisis

India's water math is stark before any climate-change induced shock is factored in: the country holds roughly 18% of the world's population but only about 4% of its freshwater resources. This gap has widened with rising population: Since 1970, water availability per capita has been halved. And the future looks even starker: By 2030, India’s water supply is predicted to fall 50 percent below demand.

Agriculture is a key economic sector in India: It employs over 40% of the workforce and contributes nearly 20% of GDP, while using 80 to 90% of available water, two to three times more than China or Brazil. According to the World Bank:

‘’In the past years, farmers have increasingly turned to groundwater, making it the dominant source of irrigation. However, unsustainable use of groundwater has led to the widespread depletion of this precious resource in many areas’’.

Addressing India’s water crisis therefore requires changing how farmers use water. This is particularly true of rice farming, which accounts for 40% of India’s irrigation water use.

This challenge is becoming more pressing with erratic rainfalls derived from changes in the monsoon cycle: Precipitations depend on the monsoon and are highly seasonal with 70% occurring in only three months.

What is happening this year

2026 is compounding that structural deficit with a bad monsoon year. This year, the India Meteorological Department is forecasting rainfall at only about 90% of the long-period average, with a 60% chance of a deficient season, as an emerging El Niño — which NOAA models suggest could strengthen into one of the more significant events on record and persist into the 2026-27 winter.  

The early warning signs are already visible in reservoir data: storage across India's 166 major reservoirs fell from 38% of capacity in late April to just 32% by July 2026. With roughly 60% of India's farmers dependent on monsoon rainfall for the kharif season, and government agencies already flagging 150-200 districts as vulnerable, a weak 2026 monsoon threatens to turn a chronic groundwater crisis into an acute one. 

Changing irrigation practices in rice agriculture matters more than ever now.
