Agropastoral farms in northern Cameroon face the challenge of adding value to their plant and animal coproducts in order to increase their resilience[Les exploitations agropastorales du Nord-Cameroun confrontées au défi de la valorisation de leurs coproduits végétaux et animaux pour accroitre leur résilience]

Description of the subject. Agriculture-livestock integration is one of the strategies adopted by agropastoralists in the North Cameroon region to reduce the risks associated with demographic pressure and climate change, in order to improve their productivity. Objectives. The aim of the study was to characterize the systems and practices for managing and recycling animal and plant co-products on agropastoral farms in northern Cameroon, as this is one of the keys to agroecology in agropastoral systems. Method. An in-depth survey was conducted on 108 selected farms. The data were analyzed using multivariate analysis (PCA) followed by classification (CAH). Results. Characterization according to farm structure, co-product management practices and technical performance enabled us to identify four classes of farm, namely small farms mainly focused on crop production (class 1), farms specializing in livestock farming (class 2), medium-sized farms combining crop production and livestock farming (class 3) and very large agro-pastoral farms (class 4). On average, farms used 28% of plant by-products to cover 25% of their fodder requirements (straw, tops), and 23% of animal by-products to cover 35% of their organic manure requirements (animal waste). Conclusions. This study showed that the recycling of co-products in agro-pastoral farms is low but increasing.
