A Study on the Establishment of Criteria for Reduction measures of Mega Drought in Korea

Recently, climate change due to global warming has been frequented by large-scale weather disasters that have not been experienced in the past. Among various weather disasters, drought is one of the representative weather disasters in Korea recently along with heavy rains. In the case of drought, it occurs in a wide range in the short term and long term, and it is difficult to identify specific occurrence times, places, and causes, and damage and influence are enormous.

In the past, the Republic of Korea has been prepared with non-structural measures such as securing irrigation water for drought restoration, developing emergency management, and developing a drought information system based on drought index. The reduction measures for drought degradation were mainly used by Palmer Draught Severity Index (PDSI), Standardized Precision Index (SPI), Crop Moisture Index (CMI), Crop Specific Drug Index (CMI), and Profication (DICS Index), and Survey.

In this study, we intend to establish standards for reducing drought damage by investigating and analyzing drought damage characteristics in Korea. In the past, drought damage in Korea occurred in agriculture, living and industry, and the ministry manages and stores the data on drought damage. The drought damage in South Korea from 1965 to 2018 occurred a total of 204 times, mostly in South Gyeongsang and South Jeolla provinces, rather than in special cities and metropolitan cities. The purpose of this study is to analyze the characteristics of drought damage in Korea and establish the measures to reduce mega drought.
