Extreme heat has become a defining urban challenge in India, with Delhi illustrating how rising temperatures interact with dense built environments and unequal access to cooling. While Heat Action Plans (HAPs) set out a broad response framework, they do not yet incorporate granular evidence on how people’s ability to cope differs across neighbourhoods.

This study addresses that gap by integrating high- resolution climate and remote-sensing data with a primary survey of households to understand the spatial, social and behavioural dimensions of heat vulnerability at a neighbourhood-level in Delhi.
