Study the implementation of forest decentralization in Cameroon is the subject of this research that the main issue is whether the transfer of forest management to councils and local communities led to new forms of governance contributing to the socio-economic local development and the conservation of forests in the Eastern region. The results of this study, based on multidisciplinary methodological approach and using governance as a framework for analysis, indicate unequal interdependence relationship between the councils and logging companies on the one hand and between village communities and loggers in the other. They also indicate the dependency of these three categories of actors toward state institutions whose authoritarian power remains strong and meaningful. With regard to the local development and the conservation of forests expected, the analysis shows results below expectations in the councils of Gari Gombo and Yokadouma. Although we note some socio-economic benefits for local people, but overall many weaknesses limiting for effective governance are highlighted. The prospects for the effectiveness of governance in Cameroon in general, and in the study area in particular, suggest an organisation of collective action around a shared goal, for the local development and the forest biodiversity conservation, between relevant strategic actors. In addition, it is also necessary that the council and community forests generate sufficient incomes to their beneficiaries, to achieve local development projects and to ensure forest regeneration.
