<p>Cities now face more heat-related risks due to rapid urbanization and climate change. This study develops a detailed Hazard Risk Index (HRI) framework to assess the spatial variability of heat risk in Jaipur, undergoing significant land-use changes and rising LST. To ensure the robustness and internal consistency of the index, the study integrates data from field surveys with statistical methods such as descriptive statistics, t-tests, Principal Component Analysis (PCA), and KMO-Bartlett tests. The intra-urban differences between the Greater and Heritage Jaipur zones are shown by the spatial mapping of HRI components. Simultaneously, factor analysis and qualitative insights from case studies and FGDs are used to study resilience, capturing lived experiences of heat stress and adaptive behavior. The findings indicate consistently higher HRI scores in densely populated, commercially vibrant, and developed zones, attributable to increased exposure, insufficient institutional support, and restricted individual adaptability. The peripheral zones, such as Jhotwara, Bagru, Adarsh Nagar, and Kishanpole, have a relatively higher hazard risk. This higher hazard risk is mainly due to rapid and frequently unplanned urban expansion, elevated LST, and a mismatch between increasing exposure and inadequate heat-responsive infrastructure. Rising heat exposure results in significant health outcomes, including heat exhaustion, dehydration, diminished work efficiency, and chronic stress, particularly affecting outdoor workers and vulnerable populations. To better comprehend urban heat risk, the study emphasizes the significance of combining quantitative HRI evaluation with resilience analysis. It advocates for specific measures, ranging from home tactics to citywide governance solutions, to increase resilience in warming cities.</p>
