In the context of growing tourism and global warming, the fragile landscape of the Himalayas is under immense pressure because of rapid land cover changes in developing countries like Nepal. Remotely sensed data combined with ethnographic knowledge are useful tools for studying such changes. The quantitative change can be measured analyzing satellite images whereas local people’s perceptions provide supportive information. To measure such changes in Sagarmatha National Park of Nepal, Multispectral Scanner (MSS) and Thematic Mapper (TM) images since 1972 were used. Normalized Difference Vegetation Index (NDVI) was calculated for different elevation classes and land cover types. These measurements, along with land cover change (1992- 2006) analysis, shows a significant conversion of the areas covered by ice, shrub and grass to rock and soil. Factors including political conflict due to a Maoist rebellion group, inactive park management, increasing tourist demand, and consequent natural resources exploitation helped to explain the change in the forested areas. This is supported by the information from short, informal, semi-structured interviews with local people. However, the local people are unaware of global warming, which has caused the ice melting and glacial lake expansion. Although global causes are out of the immediate control of land managers, better management practices and managed tourism might help alleviate deteriorating Himalayan ecosystems.

The aim of this dissertation is to assess the political ecology of conservation governance and management of Sagarmatha (Mount Everest) National Park (SNP), SNP Buffer Zone (BZ) and the Buffer Zone Community Forest User Groups (BZCFUG) in Pharak in northeastern Nepal. It evaluates their performance in two adjacent regions (Khumbu and Pharak) from multiple perspectives, including the views of the residents (indigenous Sherpa people and minority immigrant community members), and the standards of current international conservation and human rights policies. This research is important because it relates to global, regional, national and local level conservation policies and practices, which have direct impacts on biodiversity conservation, climate change adaptation, the livelihoods of indigenous peoples and local communities, and rights. The discussion of buffer zone community forest in the Pharak region follows my M.Sc. thesis completed at the University of Wales, UK in 2000. This dissertation draws on my 2011 fieldwork and my long-time experience growing up in this region and working there for conservation and development organizations. I conducted qualitative research adopting field observation, semi-structured and focus group interviews and participating in BZ and BZCFUGs' meetings. I observe that implementation of CFUG, BZCFUG and buffer zone management programs (BZMP) in Pharak and BZMP in Khumbu have made significant progress towards achieving conservation of forests, habitats, wildlife species and sustainable production of forest products while reinstituting forest and natural resource use and improving management and governance rights. This suggests that community participation in forest commons and natural resource management and governance through devolution and decentralization of decision-making rights can achieve biodiversity conservation goals. By integrating indigenous peoples' and local communities' cultural and religious perspectives with scientific knowledge, a synergy can be achieved that benefits conservation. For this the free, prior and informed consent of the concerned indigenous peoples and local communities is prerequisite. Conservation goals need to consider the rights of indigenous peoples and local communities and meet their aspirations and international conservation standards of self-determination and autonomy.
