Abstract: Biogas is a clean energy of the greatest development value in the agricultural and pastoral areas in Tibet. Household biogas development in the agricultural and pastoral areas in Tibet can solve the energy shortage problems in constructing new agricultural and pastoral areas. However, problems exist in household biogas development in Tibet:inadequate understanding of investment sources and returns, imperfect technology innovation and support in biogas development, unclear goal setting, and lack of investment risk sharing mechanism. To solve those problems,it is necessary to establish a mechanism for sustainable development of household biogas in agricultural and pastoral areas in Tibet with emphasis on encouraging policies,government responsibilities, and market orientation.

Key words: Tibet, agricultural and pastoral areas, household biogas, clean energy, biogas development, sustainable development
