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 co

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.
