Severe Heatwaves in Eastern India: Analyzing Geophysical Drivers and Governance Responses

From a governance perspective, heatwaves are no longer just seasonal discomforts but are recognized as major disasters with profound socio-economic ramifications. The public health infrastructure faces increased pressure from heat-related illnesses, while the 'wet-bulb temperature' threshold poses a lethal risk to outdoor laborers in the construction and agricultural sectors. Furthermore, the agricultural sector faces 'heat stress,' leading to reduced soil moisture and potential crop failures, which can trigger food inflation. The primary administrative response involves the implementation of Heat Action Plans (HAPs). While many states have developed HAPs, their effectiveness depends on local-level execution, such as adjusting school timings, providing public cooling centers, and ensuring water availability. However, policy experts argue that current HAPs often lack legal backing and dedicated funding, highlighting a critical gap in India’s disaster management framework that needs to be addressed through integrated urban planning and climate-resilient infrastructure. UPSC Relevance: This news serves as a critical case study for GS Paper I (Geophysical phenomena) and GS Paper III (Disaster Management). It illustrates the intersection of climate change, public health, and administrative preparedness. Aspirants should use this to discuss the limitations of current Heat Action Plans and the necessity of long-term heat mitigation strategies in Mains answers.
