Abstract
Research on the risks of climate change to urban regeneration projects has been insufficient to date. Therefore, this study aims to compare and analyze the degree of risk of climate change impact on areas with and without urban regeneration projects (for Eup, Myeon, and Dong regional units) in Busan, South Korea. In this study, (1) climate change risk indicators were extracted based on the concept of risk (hazard, vulnerability, and exposure), (2) a spatial analysis was performed using a graphic information system (GIS), and (3) the primary influencing factors were derived through a logistic regression analysis. The principal results show that urban regeneration areas have a higher risk of climate change impact than other areas. The results indicate that urban regeneration areas have a higher population density per area and more impermeable or flooded areas can increase the risk of climate change impacts. We also discuss strategies to develop resilient cities and climate change adaptation policies for future urban regeneration projects.
Highlights
This study analyzed spatial differentiation and the degree of impact among climate change risk indicators from the perspective that urban regeneration sites could be more vulnerable to climate change risks
By demonstrating that urban regeneration sites are vulnerable to climate change, this study suggests improvements for future urban regeneration projects
The primary results of this study prove that urban regeneration sites have a higher risk of climate change impacts than sites without urban regeneration
Summary
Urban regeneration projects attract researchers and policy makers globally because of the positive social, cultural, environmental, and physical impacts of these projects on declining urban areas [1,2,3,4,5]. Urban regeneration projects have not focused on the resilience of these declining urban areas, which includes their response to mitigating the impacts of climate change on their residents. The most important reason for researching the impacts of climate change on urban regeneration projects is related to the infrastructure in these areas. Declining urban areas are concentrated in old apartment buildings, multi-family houses, and commercial business buildings and are vulnerable to the effects of climate change [6]. If urban regeneration projects fail to prevent or manage the response to climate change, damage and negative impacts on people are expected in urban regeneration sites that are vulnerable to climate change
