Against the backdrop of rising rents, gentrification, displacement, and the criminalization of poor and homeless people in cities worldwide, a growing number of urban grassroots groups and social movements are fighting for their “right to the city.” At a recent two-day workshop, the Rosa Luxemburg Stiftung — New York Office and the Right to the City Alliance (also based in New York City) brought together housing justice groups from six European and three U.S. cities working on a variety of issues: gentrification and tenant rights, foreclosures and evictions, homelessness, and neoliberal city redevelopment. The goal was to determine the commonalities, differences, and best practices of these groups in order to network and learn from each other — thus contributing to better organized and more effective grassroots movements for housing justice at a time when the powers and interests of finance are tearing communities apart and dispossessing millions.
