In cities across the world grassroots initiatives organize alternative forms of provisioning, e.g. food sharing networks, energy cooperatives and repair cafés. Some of these are recognized by local governments as engines in sustainability transitions. In this talk, I will discuss different ways that local governments interact with, and use, such grassroots initiatives, drawing from case studies in Berlin and Gothenburg. An argument will be made for that we need to reconsider what municipal infrastructure should entail, i.e. not only the traditional infrastructure for transport and waste but also new infrastructure for repairing and sharing. Karin Bradley is Professor of Urban and Regional Studies at KTH Royal Institute of Technology, Stockholm, Sweden. Her research concerns planning and policy for sustainability transitions, the role of civil society, alternative economies and justice aspects of transitions. She has been the co-director of the eight-year research programme Mistra Sustainable Consumption – from niche to mainstream that engages researchers from different disciplines as well as municipalities, civil society organizations, companies and national authorities in Sweden. She has had several assignments for the Swedish government, including leading a public inquiry on the sharing economy.
