Die Neunte Stadt
- Research Projects
In the collaborative research project Urban Region Ruhr 2030 the Department of Spatial Planning supported the cities of Duisburg, Mülheim an der Ruhr, Oberhausen, Essen, Gelsenkirchen, Herne, Bochum and Dortmund in creating a model for cooperation and attachment. The research project (2001-2004) influenced regional and municipal policy practice: the Urban Regional Contract 2030 forms the basis for master plans and a regional land use plan for cities. The book The Ninth City underlines the research relevance of spatial planning. Spatial developments can be analysed and shaped by border studies, the theory of polyrational cooperation, and possibility management.
