We analyze the socio-political dimension of spatial development. We focus on the following questions: (1) Why and how are resources regulated e.g., land, housing, scenic landscape, food, biodiversity? (2) Which strategies are followed by actors to secure their access to resources? (3) Which institutions (rules of the game) provide a contribution to strong sustainability? In particular our research aims to understand how land-use planning can contribute to fight against urban sprawl, how affordable housing can be secured and how sustainable food provision can be ensured.
