"In the last years after the fall of the Iron Curtain, migration to Vienna rose significantly so that in some parts of the city the share of foreign population increased up to 30% and more. One of the most visible results for public life in the city was the development of "ethnic parks" in traditional working class neighbourhoods. From some parts of the public this was seen as the first sign for the development of "slums". New users brought in unusual patterns of use, conflicts between different use groups arose, and tensions were high especially during hot summer days (and nights). Political attention focused on park life more thanever before, and public perception was partly painted in black and white ("Vienna should not become Chicago"). Traditional concepts for the management and the design of these urban spaces were no longer suitable. As apolitical reflex a new form of park management was established. The goals of this study have been first of all to find out what's really going on in those parks, then to identify how the different social and cultural background of residents influences the pattern of use, and last but not least how characteristics of the built environment influence the behaviour of park users. The second goal was to review the exiting strategied for design and management of those public spaces and contribute to the development of a new strategy, instead of ad hoc interventions for those parks."
