Analyzing the Spatial Characteristics of Disaster Vulnerable Areas Prone to Sea-Level Rises

This study aims to examine the spatial characteristics of disaster-vulnerable coastal areas affected by sea level rise and derive policy implications for developing region-specific disaster prevention strategies. Based on previous research, physical, environmental, and social indicators were collected to identify vulnerable areas through a disaster vulnerability assessment. The analysis revealed that administrative districts located in low-lying and coastal zones exhibited relatively high levels of vulnerability. In particular, socio-demographic factors such as population density, the proportion of the elderly, and accessibility to disaster prevention facilities were found to exacerbate vulnerability when combined with physical risks. By adopting a quantitative approach, this study clarifies the structural characteristics of spatial vulnerability to sea-level rise and is expected to provide empirical evidence for prioritizing management areas and formulating differentiated disaster risk response strategies.
