The special issue aims to investigate processes, projects and (new) terrains of resistance in the urban. Urban social movements striving for environmental and climate justice, energy democracy or “the right to the city” have emerged all around the world. They oppose against the privatization, commercialization and commodification of nature, public spaces and infrastructure. They share the idea of creating new urban commons and democratic forms of controlling them (be that water and energy re-municipalization, urban gardening, repair cafés, do-it-yourself-and-with-others initiatives, fab labs, new types of housing etc.).
