Climate Change and Heatwaves in India: Review of Impacts on Public Health, Livelihoods, and Policy

Abstract

This paper presents a literature review studying the impacts of climate change and heatwaves on public health and livelihoods, with a focus on India. As global climate change accelerates, heatwaves are becoming more frequent and intense, necessitating new approaches to mitigate their effects on vulnerable populations, especially in urban areas. The review draws on recent studies (2021-2024) that explore the intersections of climate change, heatwaves, public health, livelihoods, policy interventions, and Heat Action Plans. The main findings reveal that heatwaves in India have significant public health impacts, such as increased mortality and morbidity, and disproportionately affect livelihoods, especially in agriculture and informal labor sectors. Vulnerable populations, including urban dwellers and informal workers, face heightened risks, further exacerbated by inadequate infrastructure and policy gaps. The purpose of this review is to synthesize current research to highlight these vulnerabilities and identify gaps in knowledge and policy response. A comprehensive, localized approach combining detailed risk assessments, nature-based solutions, technological innovations, and strengthened governance is essential for effective heatwave management in India. The findings underscore the urgent need for continued research focused on local spaces and comprehensive policy interventions to address the escalating risks posed by climate-induced heatwaves, setting the groundwork for future research and effective heatwave management strategies.
