The rise of the Occupy movement, the Arab Spring and the Wikileaks controversy has demonstrated that the internet can play an important role in helping people to organise against unjust systems. While governments may be able to control individual activists, they can no longer control the flow of information. However, the existence of new information and communications technologies does not in itself guarantee that peoples' movements will win out against authoritarian governments or the power of economic elites. Drawing on extensive interviews and fieldwork, this book illustrates the importance of contributions from local movements around the world to the struggle for global justice. Including detailed case studies on opposition to genetically-modified crops in the south of India, and the digital liberties movement, this book is vital reading for anyone trying to understand the changing relationship between science, technology, and progressive movements around the world. This book will be of interest to students and scholars of International Politics, Social movements, Global Justice and Internet politics.
