Rights to forest products are difficult to decide in situations when traditional management institutions exist parallel to formal ones. Such situations raise the question of whether the institutions are complementary or prescribe contradictory rights and management principles. Based on a household survey and key informant interviews, the article focuses on how diverging management principles can be harmonized to satisfy national forestry goals in Nepal. Villages in the Trans-Himalayan district of Mustang used to manage forests according to their traditional institutions but after 1993 they were included in a new management regime called Conservation Area Management Committees (CAMCs). The findings revealed that the villagers appreciated development initiatives undertaken by the CAMCs but three disjunctions regarding forest management existed between the CAMCs and traditional institutions: there was a disjunction between the two sets of rules for forest resource utilization; there were role dilemmas of local residents who were entrusted with CAMC implementation; and there were spatial disjunctions when formal administrative forest borders did not coincide with customary ones. The simultaneous existence of two institutions thus blurred the rights to forest resources. The author concludes that knowledge of the disjunction between parallel institutions is vital for accommodating new management schemes such as REDD+. 相似文献

Probabilistic seismic hazard analysis in Nepal 总被引：3，自引：0，他引：3
The seismic ground motion hazard for Nepal has been estimated using a probabilistic approach. A catalogue of earthquakes has been compiled for Nepal and the surrounding region （latitude 26% N and 31.7% N and longitude 79° E and 90° E） from 1255 to 2011. The distribution of catalogued earthquakes, together with available geological and tectonic information were used to delineate twenty-three seismic source seismic source information and probabilistic earthquake hazard prediction relationship, peak ground accelerations （PGAs） have zones in Nepal and the surrounding region. By using the parameters in conjunction with a selected ground motion been calculated at bedrock level with 63%, 10%, and 2% probability of exceedance in 50 years. The estimated PGA values are in the range of 0.07-0.16 g, 0.21 0.62 g, and 0.38-1.1 g for 63%, 10%, and 2% probability of exceedance in 50 years, respectively. The resulting ground motion maps show different characteristics of PGA distribution, i.e., high hazard in the far-western and eastern sections, and low hazard in southern Nepal. The quantified PGA values at bedrock level provide information for microzonation studies in different parts of the country. 相似文献
