Several devastating conflicts have persisted in Sub-Saharan Africa for the past 20 years or more. Some countries are still emerging from the era of cold war politics, while debilitating internal struggles continue to plague others. Ethiopia, Namibia, South Africa, Uganda, and more recently, Angola and Mozambique are examples of the former. The latter is illustrated by the situation in countries such as Liberia, Somalia and the Sudan. This study, the transition from war to peace in Sub-Saharan Africa, offers practical guidance and examples of good practice for improving the design and implementation of programs for demobilization, reinsertion, and reintegration of ex-combatants and their dependents in client countries. It also provides a list of early warning signals that indicate whether the demobilization and reintegration programs (DRPs) process is not going according to plan and suggests preventive actions. Work on the ground, as well as case analysis in countries such as Ethiopia, Namibia, Uganda, Angola, Mozambique, and Rwanda form the basis of the suggested good practice in DRPs.
