Flood vulnerability characteristics considering environmental justice and urban disaster prevention plan in Seoul, Korea

Abstract

This study aimed to evaluate environmental injustice and analyze ood vulnerability characteristics in consideration of environmental justice and urban ood disaster prevention planning. We investigated various urban disaster prevention factors applied to the urban development process in Seoul from the perspective of environmental justice. Flood risk areas were identi ed and ood damage data from 2000 to 2018 were collected. Furthermore, a panel analysis was performed and the nal model was selected. The ood vulnerability characteristics were found to be detached houses having basements, aged detached houses, land area for detached houses, public assistance recipients, and population aged 65 years or above, which had impact factors of 8.323, 3.781, -2.877, 3.257, and 2.637, respectively. The results indicate that not only the socially vulnerable population lacks the ability to respond to oods, but buildings and areas with poor residential environments also suffer from ood damage. This implies that there is socioeconomically disproportionate exposure (termed as environmental injustice) in the process of urban ood prevention planning and urban development. Our results can contribute qualitatively and quantitatively to prepare a ood prevention plan based on environmental justice paradigm.
