Deterioration of environmental resources in South-East Asia, such as deforestation that is mainly caused by commercial logging, shifting cultivation and forest fire, is deeply related with the economical gaps between developed countries and developing ones. Therefore in order to construct the sustainable utilization systems of environmental resources and to improve quality of life, integrating of environmental conservation, regional development and social development is indispensable. LAO PDR, mainly located within the watershed of the Mekong River, is a landlocked country and the GDP per capita is only about US$ 220 in 1992. The forest converage, which is estimated about 47% in 1981, has decreased more than 20% during these fifty years. This paper mentioned (1) total framework of environmental resources management and utilization systems, (2) feasible strategic subsystems for sustainable development, (3) bottom-up participatory approaches of local farmers for regional management.
