The objective of this work is to evaluate the relationship between organic farming and food security in Cameroon. To achieve this, our study focused on field surveys through semi structured interviews in the Central and Littoral regions of Cameroon, a bibliographical review of gray and scientific literature, construction of the analysis grids; Definition of the typologies of organic agriculture and their potential consequences on food security based on a prototype developed in Benin as part of the ABASS project (Diversity of biological agriculture in sub-Saharan Africa and contribution to food security); Organization of two reflection workshops in the Central and Littoral regions of Cameroon, as these are the areas where most governmental and non governmental institutions and enterprises are located. These workshops were the occasion to mobilize a typology of actors because of their important contribution to the debates in progress on the models of agricultural development and that of organic farming in order to define organic farming in the context of Cameroon, To share knowledge bases on the topic among participants and to characterize its relationships or interactions with food security. These actors were: • the current national research institutions (institutes and universities) or international organizations favoring emergence3 organic farming; • State structures, non-governmental organizations, extension structures capable of putting in place regulatory mechanisms for organic farming; • contractors either in the agri-supply sector for the AB (bio-fertilizers, seeds, biological control agent...), or that of the production (farmer) and the agro-food processing of the products. At the end of this work, we arrive on the one hand to the result of the existence of three types of organic farming in Cameroon: “certified”, “natural”, “hybrid”. On the other hand, to evaluate the potential consequences of these biological agricultures on each dimension of food security.
