Environmental impact of integrated inner urban development concepts on the infrastructures of urban growth regions

Cities in growth regions face massive challenges. A booming economy and large-scale immigration are leading to tight land and housing markets. The question increasingly arises as to what extent the potential of inner development can meet the quantitative and qualitative requirements for the provision of living space and what synergies, but also burdens, can be identified with regard to the technical infrastructures in the cities. technical infrastructures in the cities. The project focused on large cities with more than 100,000 inhabitants in growth regions. The cities of Leipzig, Karlsruhe, Freiburg im Breisgau, Ulm and Osnabrück were selected as model cities for interdisciplinary cooperation. For each of the model cities three scenarios for population and land development were developed. All scenarios take into account both indoor and outdoor development for residential and commercial purposes, but with different emphases. These scenarios also formed the basis for the economic and ecological considerations based on them. The scenarios resulted in all five model cities a high rate of possible coverage of demand for residential units (WE) through internal development (incl. conversion) for the internal development scenario. As a result, between 38.5% and 92.4% of the WE required according to the projections could be met in the period 2020 to 2030 could be provided by internal development (incl. conversion). The prerequisites and framework conditions are different in each model city, so that comparisons between the cities are not meaningful or purposeful. Six recommendations for action were developed from the project, which meet the challenges with regard to the development of inner development potential, taking into account the technical infrastructures.
