In Summary

  • Extreme heat threatens Indian agrifood systems, risking rice, wheat, fruit, vegetable, dairy, and poultry yields due to pests and rainfall deficits.
  • Wet-bulb temperature extremes could reduce agricultural workers' capacity by 40% by 2100 under high-emission scenarios.
  • Recommendations include on-farm adaptations, early warning systems, financial services for farmers, and climate change mitigation.

In Summary

The Report warns that extreme heat is pushing global and Indian agrifood systems to the brink.

Key highlights of Report regarding Indian agriculture

  • Food Security Risk: Heatwaves are a major threat to Indian rice and wheat production, with the Ganges and Indus River basins facing the most intense risks.
    • Also, the yield for fruits, vegetables, dairy and poultry are projected to decline rapidly due to increased insect pests, diseases outbreaks, rainfall deficit, etc. with the rising heatwaves.
  • Threats to Agricultural Workers: by the end of 21st century under high-emission scenarios, wet bulb temperature extremes could lead to 40% fall in work capacity.
    • Wet-bulb temperature is the lowest temperature air can reach by evaporating water into it. It is a combined measure of heat and humidity that represents how effectively sweating can cool a person down.

Recommendations and Adaptation Strategies

  • On-Farm Adaptation and Innovations: such as heat-tolerant crops and livestock breeds, adjusting planting schedules, and altering management practices like improved irrigation and shading.
  • Early Warning Systems: such as seasonal outlooks, are vital to help farmers anticipate risks and implement protective measures.
  • Access to financial services: such as cash transfers, risk insurance and shock-responsive social protection  to vulnerable farmers are essential to recover from extreme heat damages and avoid poverty spirals.
  • Climate Change Mitigation: protecting global food security requires a decisive transition away from a high-emissions future.
