Collectives that produce knowledge for action: feedback on legume production in Burgundy-Franche-Comté.

Summary Among the questions raised by the injunction to green agriculture, we seek to understand how crop rotation practices are evolving, particularly what leads farmers to insert legumes. This article explores how farmer collectives contribute to the adoption of new practices. Seventeen interviews conducted in Burgundy Franche-Comté with farmers who already include legumes in their crop rotation explored what collective work between peers brings to their exploration practices. Belonging to such groups allows farmers to regain a sense of decision-making autonomy, to pursue and achieve specific objectives, to learn and develop their knowledge, and to socialize. What stands out is the cognitive contribution of groups where knowledge is not only shared and exchanged, but also constructed. The collectives also provide moral support and are seen as facilitating tools for the development of agroecological practices.
