Urban Resilience and Climate Change: Developing a Multidimensional Index to Adapt against Climate Change in the Iranian Capital City of Tehran

Urban resilience studies have increased during recent years due to the significance of climate change as an alarming issue in centralized and highly populated cities where urban functionalities are disintegrated. Towards this aim, an Exploratory Factor Analysis (EFA) was enrolled to streamline the urban resilience to climate change over the 22 districts in Tehran after assessing the resilience objectivity. Based on the results, the city coverage was classified into best (41%), moderate (15%), low (14%), and least resilient (30%). In addition, the urban municipal districts were classified into five functional zones including Wellbeing-wealth (WWZ), Ecological Conservation (ECZ), Core (CZ), Downtown (DZ), and Neutral Zone (NZ) after evaluating the concept of urban functionality in the resilience framework. The results indicated that the socio-cultural component is considered as the fundamental necessity, along with eco-environmental and economic components in capacity building to urban climate resilience. In fact, more than half of the Tehran coverage is regarded as resilient. Thus, the rest should be prioritized, despite the need to inspire from top-ranked districts, especially D4. However, downtown and neutral zones, especially D9 and D21, which account for up to 12% of the least resilient areas, should be evaluated seriously. Finally, the robustness of the proposed methodology was compared to the studies addressing the same concept, and we offer some preparatory and adaptive measures for urban planners and policymakers
