Cities are or have become the key locales of everyday life. Since a few years now, the majority of the world’s inhabitants is living in cities, and with this the protection of ‘the urban’ has become an ever more important challenge: The securing of the city, i.e. the development of comprehensive security dispositives specifically targeted to urban habitats, has become a pressing policymaker issue, and it now also emerges as a new research topic in international security studies. This 2016-2019 Swiss National Science Foundation Ambizione research project, institutionally attached to ETH Zürich’s new Institute of Science, Technology and Policy, contributes to this new security studies focus on cities. Based on a comparative empirical analysis of urban protection policies and practices in Switzerland, Morocco, Rwanda and Nepal, it examines how urban security dispositives are turned towards an integrated management of local, national and international dangers of all sorts. It analyses how this process includes use of new tools and actors, and integration and internationalization of existing ones, and how it is influenced by political systems, technological access, cultural influences and traditions of urban planning.
