Rising temperatures and air pollution threaten to slash rice yields by up to 75% in parts of Punjab, Haryana, and Uttar Pradesh by 2035, according to new research. Conversely, rice production in Gangetic Bengal is expected to remain stable, highlighting a shift in regional agricultural resilience due to climate change.
Rising temperatures and air pollution threaten to slash rice yields by up to 75% in parts of Punjab, Haryana, and Uttar Pradesh by 2035, according to new research. Conversely, rice production in Gangetic Bengal is expected to remain stable, highlighting a shift in regional agricultural resilience due to climate change. Key Findings from the Study: Northern Region Impact: - The study projects a significant decline in rice production in India's major breadbasket states, driven by high heat stress and pollution, which is noted to exceed earlier impact assessments. Regional Contrast: - While northern areas suffer, Gangetic West Bengal's, Odisha's, and neighboring regions' rice yields are expected to remain stable, potentially increasing the region's importance in future national rice production. Causes: The reduction in yields is largely due to rising temperatures during the growing season, which affects plant growth and increases vulnerability to extreme weather eve...
