The research was held in two terrestrial sites in Luzon, Northern Philippines, where the implementing organizations are comprised of entities from different sectors. The forest rehabilitation project, which was conducted in the Marikina Watershed in Antipolo, Rizal, utilized rainforestation and analog forestry methods. Adjacent to this site, REDD+ as a framework was implemented in General Nakar, Quezon. In the forest rehabilitation site, the private sector coordinated the initiative in partnership with non-government and donor organizations and the national government. In the REDD+ site, the private sector served to fund the pilot project in partnership with the Fauna and Flora International (FFI) and the Non-Timber Forest Products Exchange Program (NTFP-EP) in the Philippines. The research involved the conduct of interviews with the implementing organizations in both sites focusing on the processes of stakeholder engagement undertaken, the measurement of effective implementation for their respective projects and potential replication elsewhere, as well as the plans following from the end of the projects and other relevant components of the project design. Emphasis was also given to the potential roles the private sector played or plays in each project, their purpose for involvement, the possible alternative arrangements resulting from their participation, and the value of private sector collaboration in future REDD or REDD+ projects in the future. The intent of the research was to see how two unique but critical projects were being undertaken on the ground. A further focus of the research was to explore the benefits sharing resulting from the REDD+ project and observe corresponding arrangements in the forest rehabilitation projects.
