Three previous RAND volumes examined the record of American-, United Nations (UN)-, and European-led peacekeeping, peace enforcement, and postconflict stabilization operations. This volume considers similar missions by the African Union and several subregional African organizations. These missions range from mediation and traditional peacekeeping to peace enforcement and extended counterinsurgency campaigns. This report contains case studies of six of these missions in Burundi, the Central African Republic, Darfur, the Comoros, Somalia, and the Lake Chad Basin. The case studies are followed by a statistical comparison of U.S., UN, European, and African missions. The report concludes with recommendations for the relevant African institutions, the UN, and other organizations and governments interested in peace and security in Africa.Of the six missions examined, two were ultimately successful, and three have shown some progress. What is most remarkable and commendable about Africa's institutional role in regional peace operations is the level of cooperation generally achieved among the states most directly affected by these conflicts. African countries do not all agree with one another but instead have established effective consultation processes. They are also able to form ad hoc coalitions to pursue their shared interests. African-led peace operations have shown the flexibility to undertake a range of different types of tasks, up to and including high-intensity combat, under different subregional or continent-wide institutions, supported by varying partners. African institutions will likely develop new capabilities for peace operations, especially if new funds become available.
