Farmers manage large areas of landscapes that are altogether designed by heterogeneous actors. Conflicts may eventually arise in complex regions like the Mediterranean where the urban and agricultural actors’ spaces for action easily overlap and concur for the use and management of soil and water. A territorial or landscape perspective is therefore required to inform the design of land management systems capable to meet the place-based development goals. Greater involvement of agronomy in the landscape arena would help to design landscape management policies that are better informed of farming systems. Our aim is to present a territorial approach that supported a prospective analysis for the design of shared land management actions using the territory game.
