In Dutch planning, there has always been an important role for spatial concepts. Their role has arguably changed with the recent decentralization of planning to the regional and local level. At the national level, guiding concepts of a more procedural nature have replaced the more substantive and place-based spatial concepts, leaving more room for regional and local interpretation. At the regional and local level, spatial concepts are still in use, but this seems to be in a more communicative, negotiating and developing role than before. In this paper, we analyse how place concepts are used to exercise power, mobilize recourses and frame meaning over the use of the peri-urban areas, in the changing Dutch planning context. This paper focuses on two competing place concepts for overlapping green urban fringe areas in The Hague Region, which have been promoted by different actor constellations and which represent different visions about the meaning of these peri-urban areas. The case study allows conclusions about the changing role of spatial concepts in Dutch spatial planning.
