방재력 비용 지수를 이용한 복구활동의 효과 분석

In Korea, post-disaster recovery costs were spent more than disaster losses every year, and in particularly, heavy rain events required the high ratio of recovery costs to losses. These high ratios of recovery costs to losses and their dependency on disaster types imply that we have to consider the recovery costs as well as losses to determine a priority for disaster mitigation projects.We propose the resilience cost index to be used as a standard,which is the summation of recovery costs and losses divided by exposure, such asGrossDomestic Product or population. The recovery cost spentmore than losses after disasters in Korea might be aimed to reduce future losses and subsequently recovery costs, or the future resilience cost index, rather than to get recovered to a pre-disaster state. To assess the impact of this high recovery cost on resilience enhancement, we monitor the resilience cost index. Monitoring results show that the post-disaster recovery has not affected the national and regional resilience yet, probably because it is too soon to see the impact given that the resiliencewas introduced in Korea only a couple of years ago. These study results showthat the resilience cost index can be used to not only support decision making in disaster management but also analyze the impact of recovery activities on national and regional resilience.
