South Asia, home to nearly 25% of the global population, is disproportionately vulnerable to climate-related health risks. Rising temperatures, severe floods, prolonged droughts, and tropical cyclones have intensified public health challenges across the region, ranging from heat-related mortality to the spread of vector-borne diseases. By 2030, the World Bank projects that nearly 800 million South Asians will be exposed to life-threatening heat waves annually, while over 20% of the region’s population will face extreme flood risks (World Bank, 2025). Despite this growing crisis, national health policies remain fragmented, reactive, and underfunded, often failing to integrate climate adaptation into health system strengthening.
