International audienceThe communication will present the methods, results and implications of the AF Filières project which main objective is to improve knowledge on agri-food and forest-wood material flows, both at the scale of France and of the 13 French regions. Results allow in particular a better understanding of potential competition between different types of biomass uses (feed, food, energy, industry etc.). Environmental footprints associated with these material flows are also studied and an iterative knowledge improvement process is set in co-construction with stakeholders. Physical Supply and Use Tables are used at every step of the analysis
