Heat Resilience Framework: A Methodological Approach to Assessing a City’s Preparedness for Heatwaves

This study applies the Heat Resilience Framework (HRF) as a methodological approach to assess and compare heat resilience across Mumbai, Thane, and Nagpur. The HRF integrates multiple dimensions, namely Physical, Social, Economic, Institutional, and Environmental, to systematically evaluate vulnerabilities and adaptive capacities at the city level. Using the Analytical Hierarchy Process (AHP), indicators within each dimension were weighted and normalized to derive a comprehensive resilience ranking, allowing for a nuanced understanding of intra-city disparities and evidence-based policy interventions. The analysis reveals that Mumbai demonstrates the highest overall heat resilience, supported by strong physical, social, and institutional capacities, although economic resilience remains comparatively weaker. Thane exhibits relatively strong physical resilience but faces challenges in Institutional and Natural dimensions, contributing to a lower overall resilience score. Nagpur demonstrates the strongest economic resilience among the three cities but continues to face challenges in social resilience and adaptive capacity in the Natural dimension. These findings highlight the need for targeted interventions, including infrastructure improvements, financial inclusivity, strengthened institutional preparedness, and community-based resilience strategies, to address city-specific vulnerabilities. The study underscores the importance of adaptive measures such as green infrastructure, cool pavements, cooling shelters, and parametric insurance to enhance urban resilience. By leveraging the HRF, this study contributes to climate-responsive urban planning by offering a structured framework for policymakers to develop targeted, data-driven heat-mitigation strategies.
