Book excerpt: This open access book on the state of peacebuilding in Africa brings together the work of distinguished scholars, practitioners, and decision makers to reflect on key experiences and lessons learned in peacebuilding in Africa over the past half century. The core themes addressed by the contributors include conflict prevention, mediation, and management; post-conflict reconstruction, justice and Disarmament Demobilization and Reintegration; the role of women, religion, humanitarianism, grassroots organizations, and early warning systems; and the impact of global, regional, and continental bodies. The book's thematic chapters are complemented by six country/region case studies: The Democratic Republic of Congo, Rwanda, Sierra Leone, Sudan/South Sudan, Mozambique and the Sahel/Mali. Each chapter concludes with a set of key lessons learned that could be used to inform the building of a more sustainable peace in Africa. The State of Peacebuilding in Africa was born out of the activities of the Southern Voices Network for Peacebuilding (SVNP), a Carnegie-funded, continent-wide network of African organizations that works with the Wilson Center to bring African knowledge and perspectives to U.S., African, and international policy on peacebuilding in Africa. The research for this book was made possible by a grant from Carnegie Corporation of New York.
