Diversity of long and dynamic sectors of transition of agri-food systems in the territories : the case of legumes in the Occitanie region[Diversité des filières longues et dynamiques de transition des systèmes agroalimentaires dans les territoires : le cas des légumineuses en région Occitanie]

In a context marked by the affirmation of the framework of agroecological transtion, agrochains strategy is a source of concern, as they are the major part of French agribusiness environment. The understanding of the link between the territorial anchorage of stakeholders and their contribution to transition dynamics in the territories seems to be essential. First, this paper examines agrochain's positioning in a context of transition, then offers a perspective on two pulses chains – emblematic crops agroecological transition – in Occitanie region, the FILEG project and the PGI red label haricot tarbais. This view leads to confront their modes of organisation and to debate in a third part about their respective positioning. Thus, it seems that actors of long agrochains implement strategies at various scales to reach development objectives, but also to benefit from local advantages and large cooperations.
