Conflicts over water are human-caused events with socio-political and economic causes. From Brazil's Movimento dos Atingidos por Barragens (MAB) to environmental activists in Pittsburgh, people are coming together to fight for control of their water. This book examines how movements are communicating and organizing against water privatization and other forms of water grabbing, and explores how movements engage with and learn from each other. Water is at the heart of this book, but Global solidarities against water grabbing is as much about collective struggle and popular organization as it is about water. Based on extensive fieldwork with two movements fighting against water privatization, the book uses anticolonial and feminist research methods to show how global communications and organizing are occurring around water and how Global North movements are engaging with and learning from the Global South and vice versa.
