Structural economic and demographic changes in the past decades inevitably lead to a reorganization of settlement structures. Relocating companies leave behind unused land in urban areas, while the growth of population in cities demands for the reclamation of undeveloped areas on the outskirts. In order to bring these two conditions in line it requires new, creative and co-operative strategies in spatial planning. Selective measures can promote the use of urban brownfields by land recycling and concurrently reduce the consumption of new land for residential and transportation purposes. Located in a built environment, brownfields offer new perspectives for the inner development of a city or township. Moreover, the use of these potentials has a significant impact on the competitiveness and the image of a city and should therefore be the binding goal of a future-oriented spatial planning. This masters thesis specifies the issue of recycling industrial fallow land and illustrates the different possibilities of reusing those sites. A theoretical approach to the topic is followed by a practical part including the analysis of three best practice projects in Austria and Germany. Finally, suggested measures can make politics and citizen more aware of the issue of land recycling and at the same time reduce the consumption of new reclaimed land.
