Abstract

Climate change is leading to an increase in agricultural droughts, with small-scale upland farming areas particularly vulnerable due to their lack of distinct water sources. These scattered mid-mountain regions are especially susceptible to agricultural droughts because they do not have well-defind sources for water extraction. This study aims to identify small-scale upland farming areas in Korea that are vulnerable to agricultural drought and in need of alternative agricultural water sources. To achieve this, evaluation criteria and indicators for irrigation-vulnerable agricultural areas were established, and these areas were extracted and quantitatively presented in terms of area and number of locations. The extracted irrigation-vulnerable agricultural areas cover an area of 10,330.7 ha and consist of a total of 2,635 village-scale farming locations, with the highest concentration of these areas in Gyeonggi-do. Based on this, an altitudinal analysis was conducted, and it was found that areas in Gangwon-do showed a lower rate of area reduction per 100 m elevation interval, while areas in Gyeonggi-do exhibited a higher rate of area reduction. This indicates that the target areas in Gangwon-do are located at relatively higher altitudes, while those in Gyeonggi-do are situated at lower altitudes. The results of this study are expected to serve as foundational data for selecting priority sites for the on-site application of alternative agricultural water systems in the future. Future studies may additionally be conduted to assess the effectiveness and economic viability of applying alternative agricultural water systems to irrigation-vulnerable agricultural areas.
