Book excerpt: Providing an overview of urban social movements from a diverse range of both empirical and theoretical perspectives, this Handbook includes not only a critical analysis of the transformations that have occurred in the urban landscape recently, but also sheds light on the strategies implemented by social actors in various socio-political and cultural contexts. It focuses on understanding better how and to what extent collective action around urban issues remains relevant in our modern world. This title contains one or more Open Access chapters.
