IMD Study Highlights Shifting Climate Zones in India
IN · Published Nov 5, 2026
• A recent study by the India Meteorological Department (IMD) has revealed significant shifts in India's climate zones, driven by changing rainfall patterns and rising temperatures. Northern India is becoming drier, with regions like Gangetic West Bengal and Bihar experiencing a long-term decline in annual rainfall between 1981 and
• In contrast, peninsular India, including the Konkan coast, coastal Karnataka, and Kerala, is witnessing an expansion of the tropical monsoon zone, indicating wetter conditions. Central India has seen a modest 2% increase in monsoon-dominated areas between 1951–1980 and 1991–

Impact & Risks

The shifting climate zones pose significant risks to agriculture, water resources, and ecosystems across India. Drier conditions in northern regions could exacerbate water scarcity and impact crop yields, particularly in Gangetic West Bengal and Bihar. Conversely, increased rainfall in southern and coastal areas may lead to flooding and changes in agricultural practices. Maharashtra's transition to a semi-arid climate could further strain water availability and farming in Vidarbha and Marathwada. These changes highlight the need for adaptive strategies to mitigate the impacts of climate variability on livelihoods and ecosystems.
