This book explores the ways that social movements are important and overlooked laboratories of learning and sources of knowledge-making, drawing on the findings from a collaborative research project which took place in Turkey, Colombia, Nepal and South Africa. It argues that social movements in the Global South, struggling in some of the most complex and conflict-affected contexts, can offer us exciting, innovative insights into the myriad of ways that movements learn and produce knowledge as they struggle for a better world. These movements advocate for marginalised communities defending their basic rights to education, health, housing, life, dignity and equal treatment before the law, often fighting against state repression and violence. Learning from the inspiring frontline, grassroots movements is at the heart of the struggle for global social justice.
