ABSTRACT: Farmland abandonment has been a significant issue in mountain regions. Thus, many studies have attempted to uncover its driving factors. Most existing studies take a large- or meso-scale view of mountain regions, and there are a few studies that provide community-level analysis. Therefore, it is unclear how ecological and sociopolitical factors are actually combined to influence farmland abandonment at a community level. Thus, we conducted a field survey in the mountain village of Ladakh, northern India, beginning in 2009 and tried to understand the farmland abandonment occurrence process from the viewpoint of traditional altitudinal models of land use. Using data collected during the survey, a relationship between altitude and farmland abandonment was established. However, this relationship was complex, combining traditional forms of land use system in the village. The altitudinal model of land use was very common in mountain regions
thus, discussions of current land use issues should be based on an understanding of such traditional altitudinal systems.
