Gesine Bär focuses her investigation on health-promoting urban development as an intervention practice. She analyzes three case studies based on urban sociological and health science research and describes local health promotion processes as project-based activities that require specific conditions to be established. The author demonstrates that only through the networking of different spatial levels can changes develop and stabilize in the long term. The work was awarded the 2015 Dissertation Prize by the German Society for Social Medicine and Prevention, as well as the AOK Promotion Prize for Dissertations at the Faculty of Health Sciences at Bielefeld University.
