The <\/span><b>IPCC Sixth Assessment Report<\/b><span style=\"font-weight: 400;\"> confirms that heatwaves have become more frequent and intense globally due to anthropogenic warming.<\/span><\/li>\n<li><b>Rapid Urbanisation and Urban Heat Island Effect<\/b><span style=\"font-weight: 400;\">: Unplanned urban expansion, concrete infrastructure, and high population density trap heat in cities, creating urban heat islands that significantly raise local temperatures.<\/span><\/li>\n<li><b>Deforestation and Loss of Green Cover<\/b><span style=\"font-weight: 400;\">: According to <\/span><b>Forest Survey of India reports<\/b><span style=\"font-weight: 400;\">, urban green cover in several metropolitan regions has declined due to infrastructure expansion. Reduced vegetation cover limits natural cooling, disrupts microclimates, and increases surface temperatures.<\/span><\/li>\n<li><b>Industrialisation and Energy Emissions: <\/b><span style=\"font-weight: 400;\">Growing industrial activity and transport emissions contribute to greenhouse gas accumulation and localized heat generation. During heatwaves in 2024, India\u2019s electricity demand reached record highs (reported by <\/span><b>Power Ministry and GRID-India<\/b><span style=\"font-weight: 400;\">), further increasing heat stress.\u00a0<\/span><\/li>\n<li><b>Geographic Vulnerability<\/b><span style=\"font-weight: 400;\">: India\u2019s tropical and semi-arid geography naturally predisposes large regions to high baseline temperatures, which are now being intensified by <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/climate-change\/\" target=\"_blank\"><strong>climate change<\/strong><\/a>.<\/span><\/li>\n<li><b>Weak Adaptation Systems<\/b><span style=\"font-weight: 400;\">: Limited urban planning for heat resilience, inadequate cooling infrastructure, and weak public health preparedness further amplify vulnerability.<\/span><\/li>\n<\/ul>\n<h2><b>Impact of India\u2019s Heat Crisis<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">India\u2019s heat crisis has wide-ranging consequences across social, economic, environmental, and public health dimensions. Its impacts are increasingly systemic, affecting both productivity and human well-being, with a disproportionate burden on vulnerable populations.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Thermal Injustice<\/b><span style=\"font-weight: 400;\">: The concept of thermal injustice highlights how heat burden is unequal across society. Heatwaves disproportionately affect the poor, elderly, children, and informal workers. According to CEEW, vulnerable groups such as construction workers, gig workers, and slum dwellers face the highest exposure to heat stress.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Economic Impact<\/b><span style=\"font-weight: 400;\">: Studies suggest potential GDP loss of up to 4.5 percent by 2030 due to heat stress (CEEW analysis).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Labour and Informal Sector Impact<\/b><span style=\"font-weight: 400;\">: Unlike those with access to private cooling, construction workers, street vendors, and delivery partners have <\/span><b>zero cooling autonomy<\/b><span style=\"font-weight: 400;\">; even small temperature increases reduce their productivity and income, forcing them to choose between health and livelihood.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Agricultural Impact<\/b><span style=\"font-weight: 400;\">: Heat stress reduces crop yield, increases irrigation demand, and disrupts sowing cycles. This threatens food security, especially for heat-sensitive crops like wheat.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Public Health Impact<\/b><span style=\"font-weight: 400;\">: Heatwaves increase heatstroke, dehydration, and cardiovascular stress. In 2024, India reported over 44,000 heatstroke cases during peak summer conditions (CEEW and media reports). However, underreporting remains a major issue due to weak surveillance systems.<\/span><\/li>\n<\/ul>\n<h2><b>Government Initiatives<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">India has taken several policy and administrative measures to reduce heat-related risks, although their implementation and effectiveness vary across regions.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Heat Action Plans (HAPs)<\/b><span style=\"font-weight: 400;\">: Implemented in multiple states and cities, these plans focus on early warning systems, public advisories, and inter-agency coordination;
