This report demonstrates the horrifying scope and magnitude of sexual violence in armed conflict. The first part of the report, the Global Overview, profiles documented conflict-related sexual violence in 50 countries - in Africa, the Americas, Asia, Europe and the Middle East - that have experienced armed conflict over the past twenty years. Each profile contains a short summary of the conflict, a description of forms of sexual violence that occurred and, where available, quantitative data on sexual violence. The second part of the report, entitled Implications for the Security Sector, explores strategies for security and justice actors to prevent and respond to sexual violence in armed conflict and post-conflict situations. It focuses in particular on peacekeepers; police; the justice sector, including transitional justice; civil society initiatives; and how DDR programmes can address sexual violence. Sexual Violence in Armed Conflict: Global Overview and Implications for the Security Sector is an important resource for security sector and development institutions, advocates, humanitarian actors, and policy makers seeking to address sexual violence during and after armed conflict.
