Working with the Centre pour l’Environnement et le Développement (CED), Cameroon, and Bioclimate Research and Development, UK, on a Congo Basin Forest Fund project supported by the UK Department For International Development (DFID). We developed a participatory process for Monitoring Assessment and Verification of ecosystem service benefits from Reduced Emissions from Deforestation and Forest Degradation (REDD) projects in two Community Forests in Cameroon. We trained local technical staff and community field workers in mapping, forest survey, and participatory approaches to defining REDD baselines, and estimating project effectiveness; and produced methodologies, technical papers, and contributions to project design documents for submission to the Plan Vivo Foundation.
