Extreme heat threatens India’s rice production, agri workers: UN report
A FAO-WMO joint report warns that extreme heat threatens India’s agricultural workers and rice production, with the Indo-Gangetic plains at high risk and labour output potentially dropping sharply under high-emission scenarios. It cites historical monsoon extremes, El Niño considerations, and outlines adaptation strategies such as altered sowing times and heat-tolerant cultivars.
Why It Matters
The findings imply significant risks to India’s food security and rural livelihoods if heatwaves intensify, calling for urgent adaptation in farming practices and labour management.
Timeline
14 Events
April 22, 2026 – rice significance and monsoon dependence noted
April 22, 2026
The report notes that 70% of India’s caloric intake comes from rice and that summer monsoon rainfall provides up to 80% of annual rainfall.
April 22, 2026 – adaptation and mitigation strategies outlined
April 22, 2026
Strategies to sustain production include using cultivars that flower early in the morning, adjusting sowing times, breeding resistant varieties, and irrigation-based cooling; crop choices and adaptive management practices are highlighted.
April 22, 2026 – El Niño expected to establish around July
April 22, 2026
The report notes that El Niño is expected to establish around July, potentially affecting rainfall and agricultural conditions.
April 22, 2026 – report release: Extreme Heat and Agriculture
April 22, 2026
The FAO-WMO joint report 'Extreme Heat and Agriculture' was released, warning that heatwaves threaten agricultural workers and rice production in India. In the Indo-Gangetic plains, average labour output could fall below 40% of normal by the end of the century under high-emission scenarios, with the highest risk around the Ganges and Indus basins.
April 17, 2025 – wet-bulb threshold questioned
April 17, 2025
Harvard researchers reported that the wet-bulb temperature survival threshold of 35°C may be too high, with studies suggesting a threshold closer to 31°C.
Spring 2025 – Kyrgyzstan Fergana heat event
2025
In spring 2025, Kyrgyzstan’s Fergana mountain range endured a prolonged stretch of about 30.8°C, causing thermal shock to crops, contributing to a locust outbreak, higher evaporation reducing irrigation capacity, and a 25% decline in cereal harvests.
2022 ICAR-CRIDA heat wave findings
2022
The ICAR-CRIDA report 'Heat Wave 2022: Causes, impacts and way forward for Indian Agriculture' noted that March and April 2022 were the warmest months on record; extreme temperatures were 8 to 10.8°C higher than normal and rainfall was 60 to 99% below normal in 10 of 36 subdivisions.
2015 monsoon severe events
2015
The report notes that severe monsoon events were observed in 2015.
2014 monsoon severe events
2014
The report notes that severe monsoon events were observed in 2014.
2009 monsoon severe events
2009
The report notes that 2009 saw severe monsoon events.
2004 Gadgil paper cited on 2002 impact
2004
A 2004 paper published in an American Geophysical Union journal led by monsoon scientist Sulochana Gadgil is cited in the report.
2002 monsoon rainfall deficit
2002
A 20% deficit in monsoon rainfall in 2002 resulted in billions of dollars in economic damage and affected more than a billion people, a finding cited from a 2004 paper led by Sulochana Gadgil.
1987 monsoon among the most severe events
1987
The report notes that severe monsoon events were observed in 1987.
1972 monsoon among the most severe events
1972
The report notes that the monsoon's most severe events during the period were observed in 1972.
