India’s agriculture sector is increasingly vulnerable to rising temperatures, with a new joint report by the Food and Agriculture Organization (FAO) and the World Meteorological Organization (WMO) highlighting significant risks to crop production and farmer livelihoods across South Asia.
The report specifically identifies rice production in India as highly susceptible to heat stress, particularly in the fertile Ganges and Indus river basins. These regions, which serve as major rice-growing belts, are now facing increasing temperature extremes that can severely impact crop growth, flowering, and grain development.
Heatwaves during critical growth stages can lead to reduced yields and poor grain quality. Even slight increases in temperature during the flowering phase of rice can cause spikelet sterility, directly lowering production. As a result, both food availability and farmer incomes are at risk.
The report warns that continued warming could disrupt food security not only in India but across the broader South Asian region. Rice being a staple food for a large population, any decline in its production could have far-reaching consequences on nutrition and market stability.
In addition to crops, rising temperatures are also affecting water availability in these basins. Increased evaporation rates and erratic rainfall patterns are putting pressure on irrigation systems, further complicating farming operations. This creates a dual challenge for farmers—managing both heat stress and water scarcity.
The report stresses the urgent need for adaptation strategies, including the development and adoption of heat-tolerant rice varieties, improved water management practices, and climate-resilient farming techniques. Strengthening early warning systems and providing timely advisories to farmers will also be crucial in minimizing losses.
Experts believe that without immediate intervention, the combined effects of heatwaves and climate variability could significantly impact agricultural productivity and rural livelihoods in India. Strengthening resilience at the farm level will be key to ensuring long-term food security in the face of a warming climate.
