Abstract |
Once drought occurs, it results in the extensive affected area and considerable socio-economic damages. Thus, it is necessary to assess drought risk and to prepare its counterplans. In this study, using various observation data on meteorological and socio-economical factors, drought risk was evaluated in South Korea. To quantify drought risk, Drought Hazard Index (DHI) was calculated based on the occurrence probability of drought, and Drought Vulnerability Index (DVI) was computed to reflect socio-economic consequences of drought. Drought Risk Index (DRI) was finally suggested by combining DHI and DVI. These indices were used to assess drought risk for different administrative districts of South Korea. The overall results show that the highest drought risk area was Jeolla Province where agricultural practice is concentrated. The drought risk map proposed in this study reflects regional characteristics, thus it could be utilized as a basic data for the establishment of drought preventive measures. |
