This study is aimed at establishing a scientific foundation for and to support policies on climate change adaptation by formulating a system for quantitative evaluation of the risks posed by human system’s socioeconomic effects in accordance with climate change. Accordingly, quantitative evaluation of climate change risks on the coastal system was executed for study regions in Korea (Mokpo, Tongyeong and Masan) in the 3rd year of our research(2016).
Climate change which began in earnest since the Industrial Revolution has already progressed substantially. The existing climate-based coastal system has displayed high levels of vulnerability in Korea and around the world and the potential risks borne by Korea’s coastal system were found to be very high from the analysis of the effect of extreme sea level rise.
The quantitative risk system proposed in this study is a model concerned with: ① development of a climate change probability function → ② computation of an effect function → ③ computation of a damage function → ④ quantification of risks → ⑤ management of vulnerability risk. By applying this model system to the coastal cities in Korea (Mokpo, Tongyeong and Masan), it was found that these systems are vulnerable even by the climate standards of the present time, and their vulnerability is projected to increase due to future climate change. These vulnerabilities were closely related to the fact that the citied were partially built on landfills, and Mokpo was found to bear the
