In the western Baltic Sea, coastal fisheries are closely linked to the economic development of coastal communities and the impacts of climate change with the increasing loss of biodiversity. For a sustainable future of fisheries, multiple interests need to be considered. These include spatial and resource conflicts, which need to be recognized between different user groups and resolved through joint dialog. The SpaCeParti project, coordinated by the Center for Ocean and Society at Kiel University, aims to contribute to this by setting up so-called living laboratories in which users are actively involved in research. SpaCeParti is a project of the research mission sustainMare "Protection and Sustainable Use of Marine Areas" of the German Marine Research Alliance (DAM).
