The article presents the qualitative review of the past and present situation of Sagarmatha National Park (SNP) in terms of conservation of natural resources and analyzes the problems in managing it. Major constraints and their solutions for promoting ecologically sustainable development of the park and its people are also proposed. The article concludes that Sagarmatha National Park, a biospheric reserve, demonstrates all kinds of interactions and demands an integrated approach for sustainable development which needs long-term planning. Absolute and immediate solutions to problems of such dimensions are rare. Reducing the problems to a bearable limit by tackling component problems of the whole ecological complex may be the best solution. (Rajeev Ranjan Singh 2007-02-18)
