Book excerpt: In what ways has global urbanization affected the political process? This book offers a reflection on the transformations of urban politics worldwide in the past four decades, from interpersonal street-level politics to transnational governing institutions. Organized thematically, the book examines urban social movements, diversity politics, environmental politics and security politics at a global level and argues that living in an urban world calls for a profound rethinking of how we act politically. Through ethnographic incursions into the worlds of youth activists, domestic workers, rioters, barrio bandits and peripheral villagers, among others, from Mexico City and Hanoi to Montreal and New York, the book makes a number of theoretical propositions to redefine the field of urban political studies. Extending the view of urban politics beyond municipal and metropolitan institutions to the broader political process in cities, this book will be invaluable to advanced students and scholars interested in our urban future. For, as Boudreau convincingly suggests, global urban life is political life.
