In our rapidly changing and contested global environment, cities are becoming increasingly important. They are home to a majority of the world’s inhabitants and act as catalysts of social, political, economic, cultural and ecological change. The MA in Critical Urbanisms at the University of Basel offers a pedagogical platform to understand these planetary transformations. Our aim is to expand the study of the urban by examining today’s social struggles and global conflicts in relation to the legacies of empire and alternative practices of world-making and knowledge production. Our work starts from the premise that the world’s urban and environmental challenges call for new ways of thinking as well as acting. Imagining alternative futures means rethinking the present—its historical making, its political unfolding and the ways in which it is made sensible.
