Cities today are increasingly at the forefront of the environmental and social crisis--they are simultaneously a major cause and a potential solution. Across the world, a new wave of urban social movements is rising to fight against corporate control, social exclusion, hostile immigration policies, gender oppression, and ecological devastation. These movements are building economic, social, and political alternatives based on solidarity, equality, and participation. This anthology develops the debates that began at the recent Transnational Institute of Social Ecology's (TRISE) conference about the dire need to rebuild the social and political realities of our world's cities. It discusses the prospects of radical urban movements; examines the revolutionary potential of the concept of "the Right to the City," and looks at how activists, scholars, and community movements can work together towards an ecological and democratic future. A fruitful conversation between theory and practice, this book opens new ground for rethinking systemic urban change in a way that challenges oppression and transforms how people work, create, and live together.
