Taiwan, in recent years, due to the extreme climate changing, natural catastrophes were occurred which influenced the publics' lives and properties. Among the public, mountainous indigenes who live in reservoir catchment are threatened the most by natural disasters. Moreover, the governance of reservoir and catchment are simplified as 'upstream water control and downstream water supply' all the year round, which exists unbalanced frame of spacial power. It is not only against the principles of environmental justice but ignores the potential value of traditional ecological knowledge toward hydrological sustainable development, that causes unstable risky factors in catchment land governance. For example, residents who live in the upstream catchment area of Shihmen Reservoir are depending on cultivation. If the government only intends to protect water and restrain the land use without thinking of resources governance policy from the point of indigenous community development, it is unrealistic and difficult to achieve sustainable development. Therefore, the aim of this research, is based on empirical study to propose a community as a basis unit , designing a multiple targets common pool resource governance pattern for promoting organic farming to construct ecological communities, and simultaneously takes sustainable development, environmental justice, land ethics, and multiple functioning agriculture watershed governance policy into account. Nowadays, although The Indigenous Peoples Basic Law has been decreed, the governance of catchment are lack of local point of views and also difficult to show indigenous subjectivity that is needed to adjust to adopt the change of circumstances. Therefore, this study is abut to apply in-depth interview, focused group, and participant observation to start field works in indigenous communities. Also, this study is going to combine traditional ecological knowledge, ecological communities as well as land ethics, multifunctional agriculture as well as organic agriculture development theories, and other analytical tools, exploring how social organization and land view support and encourage economic/ non-economic activities of land resource use. Finally, this study is going to explore the path of 'common pool resource sustainable use', taking how to frame 'ecological communities' which corresponds land ethics and local development, so that advocates cross-scale regional collaboration. In the meantime, the specific suggestions of sustainable watershed governance which correspond environmental justice are provided.
