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.  相似文献

An emerging conflict with Trans-Himalayan pastoral communities in Ladakh’s Changthang Plateau threatens the conservation prospects of the kiang (Equus kiang) in India. It is locally believed that Changthang’s rangelands are overstocked with kiang, resulting in forage competition with livestock. Here, we provide a review and preliminary data on the causes of this conflict. Erosion of people’s tolerance of the kiang can be attributed to factors such as the loss of traditional pastures during an Indo-Chinese war fought in 1962, immigration of refugees from Tibet, doubling of the livestock population in about 20 years, and increasing commercialization of cashmere (pashmina) production. The perception of kiang overstocking appears misplaced, because our range-wide density estimate of 0.24 kiang km−2 (± 0.44, 95% CL) is comparable to kiang densities reported from Tibet. A catastrophic decline during the war and subsequent recovery of the kiang population apparently led to the overstocking perception in Ladakh. In the Hanle Valley, an important area for the kiang, its density was higher (0.56 km−2) although even here, we estimated the total forage consumed by kiang to be only 3–4% compared to 96–97% consumed by the large livestock population (78 km−2). Our analysis nevertheless suggests that at a localized scale, some herders do face serious forage competition from kiang in key areas such as moist sedge meadows, and thus management strategies also need to be devised at this scale. In-depth socioeconomic surveys are needed to understand the full extent of the conflicts, and herder-centered participatory resolution needs to be facilitated to ensure that a sustainable solution for livelihoods and kiang conservation is achieved.  相似文献
