Based on numerous grassroots initiatives and citizens’ experimentations that are being invented every day around the world and on a historical and anthropological approach, this book explores different ways of combining solidarity and organization. Solidarity-based management, governance of the commons, and Buen Vivir approaches are some of the perspectives analyzed in the context of a North-South dialogue in order to formulate the conceptual framework and practical steps of a social and environmental transition. It offers both theoretical background and living examples to students, professors and researchers to better understand and better teach new avenues for management.
