기후변화 대응을 위한 양수장의 농업가뭄 취약성 실태 평가

초록

In order to implement practical alternatives to proactively cope with the agricultural drought, the potential vulnerability of irrigation pumping stationsto agricultural drought was quantitatively evaluated. Data for the 124 pumping stations which are correlatable to the three proxy variables, i.e. exposure,sensitivity, and adaptive capacity was collected by the Korea Rural Community Corporation, and then standardized considering distribution of each dataset. Finally, the vulnerability index was calculated by multiplying the weights determined by the expert survey. The results showed that the vulnerabilityindex ranged from 0.709 to 0.331 and the most vulnerable pumping stations such as Judam, Wongoo and Jinahn were mostly located in Gyeongbukprovince likely because of the climatological characteristics with high temperature and low rainfall around this area. In addition, it was found that theadaptive capacity was a dominant factor comparing to exposure or sensitivity proxy variables in contributing to the vulnerability. It is thereforerecommended that more practical alternatives should be employed to effectively reduce the vulnerability of an individual pumping station to agriculturaldrought. Furthermore, the corresponding data related to adaptive capacity should be systematically organized and managed at a field level to designreliable adaptation strategies.
