This paper deals with the coexistence of agricultural models from the perspective of land management on the urban fringe. Our goal is to show how urban local authorities deal with and influence the coexistence of models when they are involved in farmland management, and more specifically when they determine which farmer should be allocated what land and under which lease agreement. To do this, we compare public processes of farmland allocation led by French local authorities on the urban fringes of Lyon, Montpellier, and Perpignan. This geographic study is based on qualitative methods (observations, interviews, and document analysis). The comparison of seven case studies illustrates the changing balances of power on urban fringes between agricultural models and between urban and agricultural stakeholders. As urban local authorities grant them land and legitimacy, farmers willing to develop agroecology and short food supply chains may settle in peri-urban areas, where access to land is otherwise very difficult for outsiders. Some public allocations of farmland divide space between models following agronomic and esthetic criteria, but few public bodies venture to hierarchize models by an unequal repartition of land property rights. Beyond their limited spatial impact, public allocations of farmland are actually important local initiatives for the institutional recognition of sustainable agriculture models, one driver within urban policies aiming at supporting a transition towards agroecology and more sustainable food systems. Governance processes could, however, be improved if local authorities would more explicitly tackle the possible issues related to the coexistence of diverse agricultural models in space, as in public debates and policies.
