LE STUDIUM Multidisciplinary Journal. This is the final version of the article, which has been published in final form at : http://www.lestudium-ias.com/content/art-and-city-urban-space-art-and-social-movements-0; The proliferation of visual practices, engagements, and tactics on the streets and plazas of the cities connect art to the political constitution of local struggles on the one hand, and the global grassroots politics of the social movements, on the other. This project investigates the ideologies, relationships, meanings and practices that arise from the diverse interactions among the three social spheres: urban space, art, and social movements. In an innovative and multidisciplinary fashion, it addresses the pressing question in humanities and social sciences : How does art, as a cultural form, partake in contemporary urban transformations and social struggle ?
