ABSTRACT:At the international level, it is recognised that environmental problems are best handled with the participation of all concerned citizens at the relevant level. However, the development of effective models for promoting citizen participation to solve environmental issues remains a work in process. With the goal of suggesting such a model, this study focuses on the system of Landcare in Australia, a nation-wide movement of community-based natural resource management that has been tackling Australian's serious environmental problems. Through analysing the outcomes of in-field research in Australia, this study describes three characteristic elements of the Landcare movement: establishing a system and a spirit of multi-party partnership throughout the nation; securing coordinators, who with flexibility to adjust to each locale, support local groups; and maintaining a holistic support system from governments who respect the autonomy of local groups. Through the discussion, this study shows the strengths of the three elements such as the diversity of the financial sources; and the challenges regarding the provision of financial and coordinating support to the communities. Also, it shows that there are activities that local groups and their networks within the movement have carried out that aim to overcome these challenges. This indicates that it is effective to establish a program which has a system and spirit of multi-party partnership, secures coordinators, and maintains a holistic support system from governments, for promoting citizen participation to deal with environmental issues.
