Effects of demographic change for the use of natural resources – scenarios and approaches to action

For an informed and future-oriented land management - between the acute call in many places for an increased provision of building land on the one hand and the reduction of new land use as a goal of sustainable development on the other hand - reliable basic data is needed. The main objective of the project is therefore, following on from earlier nationwide surveys, to collect up-to-date data and information on building land reserves and infill development potential as well as on the status and methods of monitoring and mobilizing building land in German cities and municipalities. The project is carried out on behalf of the Federal Ministry of the Interior, Building and Community (BMI) and the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) in cooperation with the German Economic Institute (IW, Cologne). The survey is supported by the German Association of Cities and Towns and the German Association of Towns and Municipalities.
