Territorial governance and actors’ coordination in a local project of anaerobic digestion. A social network analysis

International audienceBiogas is a process for producing renewable energy, which has recently gained interest in contributing to a territorial strategy for the deployment of the circular economy. The projects, which are collective in nature, bring together multiple actors or local stakeholders from a wide variety of backgrounds. The article proposes to analyze the territorial governance of this type of project by studying the relations of synergy and cooperation between stakeholders in the case study of the Syndicat Mixte du Point Fort (SMPF) of Cavigny (France). The results of the analysis of interaction and coordination networks show that local stakeholders develop dense relational networks that vary throughout the project. This high density is indicative of the importance of group cohesion in interactions, which is necessary to create a framework of trust and consultation that favours the success of territorial renewable energy projects. The measure of centrality of the interacting actors shows that the project leader (SMPF) plays the role of assembler and facilitator of the interaction networks facilitating the sharing of flows, knowledge, and collective learning
