India has officially recognised heatwaves as a notified natural calamity, marking a significant shift in how the country responds to one of its fastest-growing climate risks.
The decision, announced on August 4, allows states to access financial support through disaster response and mitigation funds for heat-related interventions. Until now, many states could prepare heat action plans, but funding remained limited and fragmented. The notification gives those plans stronger legal and financial backing.
According to the National Disaster Management Authority, the additional resources can support measures such as cooling shelters, drinking water facilities, public awareness campaigns, early warning systems and improvements to thermal comfort in public spaces. Officials also expect the funding to encourage more cities and districts to develop local heat action plans over the coming years.
Experts say the move reflects a broader reality. Heatwaves are no longer isolated weather events but recurring risks with consequences for public health, labour productivity and urban infrastructure.
Outdoor workers, construction labourers, delivery personnel and other informal workers are among those most exposed to prolonged periods of extreme heat. Health experts also point to increased risks for pregnant women, older adults and people living in densely populated settlements with limited access to cooling.
The notification is expected to help governments move beyond emergency advisories and invest in long-term adaptation measures before temperatures reach dangerous levels. However, experts caution that funding alone will not determine success. The effectiveness of the policy will depend on how states implement heat action plans, strengthen healthcare systems and identify the communities most vulnerable to heat stress.
The significance of the decision extends beyond disaster management. It signals a change in how governments classify climate risks. Heatwaves have traditionally been treated as seasonal weather events requiring temporary responses. By bringing them within India’s disaster management framework, the government is acknowledging that extreme heat is becoming a persistent public policy challenge requiring sustained planning, institutional capacity and dedicated financial support.
