Two community based coastal resource management (CBCRM) projects, implemented in Ream National Park and Peam Krasaop Wildlife Sanctuary are the first examples of CBCRM within Cambodia’s coastline. The processes of community organizing work that is discussed in this case study are based on the villagers’ daily activities and the work of the project teams. A main message from the study is that community fisheries management has reduced illegal activities and increased level of small scale catch in the community’s managed areas at both sites. The document describes the similarities and differences in the two sites and the methodology followed in the process of organizing the community in the two sites. Various trainings, workshops, study tours and day to day learning have helped the communities to develop action plans for managing their resources. Local communities’ rights to participate in coastal resources management has also been recognized by provincial governors and technical institutions. A set of recommendations have also been made. These include additional capacity building as well as encouraging and creating opportunities for stakeholders to support and participate in the management process.
