Post-conflict peacebuilding has become a primary concern of international politics. Indeed, the UN reform agenda, including the creation of a peacebuilding commission, makes clear that more must be done to prevent societies from falling back into violent struggle. Building up domestic capacity to provide security in an accountable manner plays a crucial role in this context. Applying a security governance perspective, this volume examines a number of key issues that must be addressed by both post-conflict societies and the international community as they confront the task of rebuilding after armed conflict. This includes security sector reform (SSR), disarmament, demobilization and reintegration (DDR), rule of law and transitional justice.
