Escalating Heatwaves in North India: Climate Change and the Urban Heat Island Challenge

The implications are multi-dimensional. From a public health perspective, extreme heat leads to increased morbidity and mortality, particularly among vulnerable populations like outdoor laborers, the elderly, and children. Economically, it strains the power grid due to surging cooling demands and threatens agricultural productivity by causing heat stress in crops and depleting groundwater levels. For governance and policy, this necessitates a shift from reactive relief to proactive mitigation. While many states have implemented Heat Action Plans (HAPs), there is a need for better integration of these plans with urban local body (ULB) bylaws. Long-term strategies must include increasing urban green cover, promoting 'cool roofs,' and designing climate-resilient infrastructure. Furthermore, the recognition of heatwaves as a 'notified disaster' under the Disaster Management Act remains a critical point of discussion for better resource allocation. UPSC Relevance: This topic is crucial for GS Paper I (Geophysical phenomena) and GS Paper III (Disaster Management). Aspirants should be able to explain the UHI effect and evaluate the effectiveness of Heat Action Plans in the context of climate change adaptation and urban governance.
