Résumé
Agroecology is a paradigm for transforming our agri-food system towards greater sustainability. Technical, organisational and commercial transformations require the convergence of new cognitive, normative and regulative rules. After outlining the institutionalisation of agroecology on an international scale and in French legislation, we present a heuristic framework for thinking about agroecological transition in the agri-food sector using the multilevel perspective from sociotechnical transition studies. This perspective conducts us to build an analytical framework at the level of the value chains to strengthen the understanding of the levers and brakes of the agroecological transition.
