Drought is one of the most influential disasters in sustainable agriculture and food security of nations. In order to preemptively respond to agriculturaldroughts, vulnerability assessments were conducted to predict the possibility of drought in the region, the degree of direct or indirect damage, andthe ability to cope with the damage. Information on agricultural drought vulnerability status of different regions is extremely useful for implementationof long term drought management measures. The purpose of this study is to develop and implement a quantitative approach for measuring agriculturaldrought vulnerability at sub-district level based on agricultural water and reservoirs. To assess the vulnerability in a quantitative manner and also todeal with different physical and socioeconomic data on the occurrence of agricultural drought, we selected the appropriate factors for the assessmentof agricultural drought vulnerability through preceding studies, and analyzed the meteorological and agricultural reservoir data from 2015 to 2018. Each item was weighted using AHP (Analytic Hierarchy Process) analysis and evaluated through the agricultural drought vulnerability estimation. Theentire national vulnerability assessments showed that Ganghwa, Naju, and Damyang were the most vulnerable to agricultural droughts. As a resultof analyzing spatial expression, Gyeongsang-do is relatively more vulnerable to drought than Gangwon-do and Gyeonggi-do. The results revealed thatthe methodology and evaluation items achieved good performance in drought response. In addition, vulnerability assessments based on agriculturalreservoir are expected to contribute supporting effective drought decisions in the field of agricultural water management.
Abstract
Drought is one of the most influential disasters in sustainable agriculture and food security of nations. In order to preemptively respond to agriculturaldroughts, vulnerability assessments were conducted to predict the possibility of drought in the region, the degree of direct or indirect damage, andthe ability to cope with the damage. Information on agricultural drought vulnerability status of different regions is extremely useful for implementationof long term drought management measures. The purpose of this study is to develop and implement a quantitative approach for measuring agriculturaldrought vulnerability at sub-district level based on agricultural water and reservoirs. To assess the vulnerability in a quantitative manner and also todeal with different physical and socioeconomic data on the occurrence of agricultural drought, we selected the appropriate factors for the assessmentof agricultural drought vulnerability through preceding studies, and analyzed the meteorological and agricultural reservoir data from 2015 to 2018. Each item was weighted using AHP (Analytic Hierarchy Process) analysis and evaluated through the agricultural drought vulnerability estimation. Theentire national vulnerability assessments showed that Ganghwa, Naju, and Damyang were the most vulnerable to agricultural droughts. As a resultof analyzing spatial expression, Gyeongsang-do is relatively more vulnerable to drought than Gangwon-do and Gyeonggi-do. The results revealed thatthe methodology and evaluation items achieved good performance in drought response. In addition, vulnerability assessments based on agriculturalreservoir are expected to contribute supporting effective drought decisions in the field of agricultural water management.
