Evaluation of Drought Risk in Gyeongsang-do Using EDI

The change of rainfall pattern due to recent climate change increases the occurrence probability of drought in Korea. Unlike other natural disasters, a drought has long duration, extensive area subject to damage, and greater socioeconomic damage than other disasters. In order to evaluate drought severity, meteorological drought indices are mainly used in practice. This study presents a more realistic method to evaluate drought severity considering drought climate factors as well as socioeconomic factors which are vulnerable to disaster. To perform a spatial evaluation of drought risk in Gyeongsang-do, drought risk was defined and analyzed through the hazard index and the vulnerability index. The drought hazard index was spatially assessed using the drought index and GIS. The drought vulnerability index was also spatially assessed using the 5 socioeconomic factors. As a result, the drought risks were compared and used for evaluating regional drought risk considering regional characteristics of Gyeongsang-do.????????? ??????????????? ?????? ??????????????? ????????? ?????????????????? ????????? ??????????????? ??????????????? ??????. ????????? ????????? ?????? ?????????????????? ?????? ??????????????? ??????, ??????????????? ???????????????, ????????????????????? ?????? ????????? ?????? ?????????????????? ??????. ?????? ????????? ????????? ???????????? ????????? ???????????? ????????? ??????????????? ???????????? ??????????????? ?????? ???????????? ??????. ??? ??????????????? ???????????? ????????? ????????? ??????????????? ????????? ????????? ??????????????? ????????? ???????????? ????????????????????? ?????????????????? ??? ??? ???????????? ???????????? ????????? ??????????????? ??????. ????????? ????????? ?????? ????????? ???????????? ????????? ????????? ???????????? ??????, ?????????????????? ????????? ????????? ????????? ????????? ???????????? ???????????? ???????????????. ????????? ????????? ????????? ??????????????? ????????????
