Coastal Vulnerability Applied on Prevention and Management under Climate Change Impact

Abstract

Recently Taiwan's coastal land is highly development and utilization. Particularly in the west coastal space carry large bearing capacity. But the study assessment of the climate change capacity for coastal zoning has less researches in Taiwan. Therefore, this study discussed the management competition in laws, regulations and space, proposed the suitable designated range and criteria, established the indicators based on Chiu [1]. On the other hand, the increasing of typhoons frequency and sea level rise on the coastal impact are discussed. Combined with vulnerability in the coastal areas, through the relevant disaster risk analysis and assessment of coastal areas can be described by future adaptation strategies to climate change and coastal protection zoning basic analysis of the basis set. This study not only defined the range for Coastal Protection Areas (CPA), but also based on the suggestion of International Strategy for Disaster Reduction (ISDR) proposed the Coastal Vulnerability Index (CVI) and Coastal Vulnerability Level (CVL) fitting Taiwan's coastal environment by 10 factors and the impact of sea level rising. Finally, we developed a classification approach and designed criteria as a reference for coastal protection zone planning in the future.
