The intervention areas of the Farmers’ Research Network (FaReNe) project in the Ségou and Mopti regions are experiencing food insecurity problems caused by poor soil fertility. It was to tackle this problem that the Participatory Innovation Development (PID) approach has been used in order to identify and enhance the value of local knowledge in the field of agro-ecological intensification. It is an approach that stimulates the creativity of the farming community to contribute to the improvement of its own living conditions. It is based on a multi-takeholder partnership that includes farmers, agricultural advisors and researchers. It is an approach that puts the innovative farmer at the heart of the process.
