Book excerpt: People across the globe engage in social and solidarity economics to help themselves, their community, and society on their own terms. Community Economies in the Global South examines how people who conscientiously organize rotating savings and credit associations (ROSCAs) bring positive changes to their own lives as well as others. ROSCAs are a long-established and well documented practice, especially those organized by women of colour. Members make regular deposits to a fund as a savings that is then given in whole or in part to each member in turn based on group economics. This book spotlights women in Latin America, the Caribbean, Africa, and Asia who organize and use these associations, composed of ordinary people belonging to similar class origins who decide jointly on the rules to suit the interests of their members. The case studies show how they vary greatly across countries in the Global South, demonstrating that ROSCAs are living proof that diverse community economies do exist and have been around for a very long time. The contributors recount stories of the self-help, activism, and perseverance of racialized people in order to push for ethical, community-focused business, and to hold onto local knowledge, grounded theory, and lived experience, reducing the need to rely on external funding as people find ways to finance sustainable, debt-free business ventures. The first collection on this topic edited by two women of colour with roots in the Global South, this volume is a rallying call to other scholar-activists to study and report on how racialized people come together, pool goods, and diversify business in the Global South.
