Since land degradation have been a critical factor for North Korea famine in mid-1990s, the process of land degradation in North Korea is crucial to understand the socio-ecological effects of this famine. Despite the great necessity of soil information or actual soil map of North Korea for the land degradation research, useful data as such are sparse and generally inaccessible. Therefore the prediction and estimation of soil properties in North Korea is first needed. From this standpoint, this study focuses on developing methods to predict and map the distribution of soils and their properties in North Korea. It attempts to generate predicted soil map as a result supported by a currently available database. The main methodology used in this study is landscape delineation suggested by Park et al. (2001) referred to as “Catena Method”, which is a quantification on the soil-landscape unit from Catena concept or Nine-unit landscape model. The procedure of this study consists of four steps: The first step is identifying spatial scale of each soil-forming factor by using spatial dependency analyses. The second step is delineating soil-landscape unit based on generic landscape processes. The third step is to assign existing soil type to the delineated landscape units based on soil knowledge and ‘legacy data’. The fourth step is making predicted soil map. Following previous steps, North Korea Predicted Soil type map were made, based on KFS’s forest soil system. We added an independent soiltype for classifying podzol-like soil which does not exist in South Korea, but expect to exist in North Korea. This study is the first step for specific soil study in North Korea. The procedure of this study can be used for making more accurate soil map if we could access more information of North Korea. Moreover, the result of this study is able to use cooperation for mitigating land degradation between North-South Korea.
