This paper demonstrates that the commercial development of alternative agrifood networks does not automatically lead to their conventionalization. The authors use the theoretical framework of the sociology of market agencements, inspired by actor-network theory, to analyze the functioning of three organizations in Pays de la Loire, in France. They first describe the organizational changes that enable these organizations to support the growing markets for organic and/or local products. Then, they show that these market agencements are, nonetheless, not characterized by a lack of remunerative prices and an inevitable disconnection between producers and consumers.
