Abstract

The increasing development of urban spaces has led to the emergence of the heat island phenomenon. One of the consequences of this phenomenon is its impact on human health. The elderly in a society are among the most vulnerable people to heat waves. The present study was conducted with the aim of investigating the spatial pattern of risk caused by urban heat islands on the health of the elderly in Yazd n view of this goal, this study used the combination of social data and remote sensing. The statistical population of the study consisted of 26,169 elderly people over 65 years of age in Yazd city. The data were collected based on the latest census of the Statistical Center of Iran in 2016.In order to evaluate the intensity of urban heat islands in the five regions of Yazd city during the period from 2017 to 2022 in July, data was extracted using the MODIS 11A2 006 Aqua satellite and Google Earth engine. Then, a temperature map of Yazd city was prepared using ArcGIS software. In order to weight the exposure and vulnerability index of the elderly population, the high density of the elderly population in the regions and the ratio of the elderly population to the total population of the regions were used, respectively. Then, the data were analyzed using Creighton's risk theoretical framework. Based on the research results, three levels of urban heat risk were identified in Yazd city. The first group, high-risk areas, which were identified as critical areas due to the high levels of all three UHI intensity indicators, density,
