Agroecology at the heart of the transformations of our food system is part of national and international public policy. The development of agroecological approaches along with their valorisations in the agri-food sector are multiple, generating ecnomic, ecologic and societal values. The actors of the downstream of the sectors (farmers, providers ...) and upstream (collectors, tranformers, distributors, ...) must guarantee food sovereignty while operating the transformations that are necessary. The latter are necessarily associated with agriculture productions and the large variety of its territories and actors.
