The classification of heatwaves as a disaster highlights the severe risks posed to public health, agriculture, and infrastructure in India. Prolonged heatwaves can lead to increased mortality, reduced crop yields, and strain on water and energy resources. Vulnerable populations, particularly in rural and urban low-income areas, are at heightened risk. The move also signals the need for international cooperation to address the financial shortfall in climate adaptation measures, which could leave many regions unprepared for escalating climate impacts.
