Through the example of SCoT Du Grand Clermont, a territorial planning process, this paper shows how agriculture is integrated into an urban project for land use development. In our study, the place of agriculture in the planning depends on the actors involved during the process and on the interaction between these actors during the project. A more or less involvement of a variety of actors in the planning device, their respective weight in this one, their strategies and their interests, are variables which have an incidence on the consideration of the agriculture.
