Abstract

As heat waves are becoming more frequent and extreme due to global warming, the Seoul metropolitan government has implemented policies to plan and operate cooling centers to prevent heat-related diseases. However, there is a lack of research that finds the relationship between the spatial distribution of cooling centers and vulnerability to heat waves. Therefore, this study aims to analyze whether the distribution of cooling centers throughout 425 administrative dongs in Seoul significantly relates to regional heat wave vulnerability. For this research, variables of climate exposure, sensitivity, and adaptability of 425 administrative dongs in Seoul were considered, and vulnerable areas to heat waves were identified by analyzing the Vulnerable-Resilience Index (VRI). Also, Hotspot analysis and ANOVA were conducted to find the relationship between the distribution of heat wave vulnerable areas and cooling centers. As a result, it showed that the existing distribution of cooling centers in Seoul needs to be improved by considering spatial vulnerability to heat waves for better accessibility. Based on the spatial analysis, additional cooling centers should be installed in some administrative dongs in Jung-gu, Yongsan-gu, Seongbuk-gu, and Gwanak-gu, Seoul. The results of this study would help provide guidelines for planning cooling centers with great accessibility to a vulnerable population.
