New Delhi - As summer grips the nation, India's approach to extreme heat is showing familiar patterns, with calls growing for a more structural and rights-based response. The National Disaster Management Authority (NDMA), in its annual ritual, has again reported on increasing preparedness. Yet, the prevailing strategy largely consists of short-term fixes. These include simple measures like setting up water kiosks, issuing public advisories, and creating shaded areas at transport hubs.
The inadequacy of current approaches is underscored by the observation that many implemented plans are mere imitations of strategies developed elsewhere, lacking genuine adaptation to India's specific contexts.
A "Cooling Doctrine" Takes Shape
A significant development in this discourse is the recommendation by the 16th Finance Commission to officially declare heatwaves as a national disaster. This designation would unlock dedicated central government funding for mitigation efforts. Beyond this, there's a growing consensus advocating for a fundamental shift towards a "National Cooling Doctrine." This doctrine posits that safe indoor temperatures should be recognized as a public health right, not a luxury.

The proposed doctrine emphasizes a move towards more sustainable and technologically informed solutions. This includes leveraging materials that facilitate passive cooling, adopting reflective roofing technologies, and exploring the implementation of district cooling systems. These large-scale, centralized cooling networks, seen in cities like Singapore and Dubai, could offer a more efficient method for cooling urban environments.
Past Failures and Future Directions
For the past decade, India has been experiencing recurring extreme heat events. The current response, as articulated by various analyses, remains largely superficial and reactive. The focus on temporary measures like water availability and shade, while necessary, fails to address the root of the problem – the need for resilient infrastructure and effective long-term planning.
The concept of a National Cooling Doctrine aims to introduce a more structural approach. It champions the integration of passive cooling techniques into building designs, such as the use of reflective white roofs and materials that inherently resist heat. Furthermore, there's a recognition of the need to develop air conditioning systems that are not only cheaper and more efficient but also tailored to India's unique climate and energy grid capabilities. This suggests a departure from simply importing solutions and a move towards indigenous innovation.
