A System Dynamics Analysis of Urban Heat Waves

Abstract

In this study, we analyzed the potential determinants of urban heat waves in Korea and their dynamic relationship using a system dynamics analysis approach. We developed an integrated causal loop diagram and identified the direct and indirect factors influencing urban heat waves. The followings are the main findings of this study. First, the rise of temperature in Korea is not simply due to the increase of impervious areas affected by urbanization but should be seriously recognized as a critical issue of heat waves which may lead to the annihilation of the areas. Second, for more accurate prediction of the temperature increase and development of effective policy responses, we need a new approach that focuses on a non-linear and dynamic relationship between urban heat wave process and urban safety. Third, it is critical to explore policy measures for maintaining socioeconomic conditions and improving the level of urban safety based on the multi-dimensional examination of causal relationships across various determinants for urban heat waves in South Korea.
