Negotiated peace agreements rarely address the legacy of wartime sexual violence committed by state and non-state armed actors, even in cases where mass rape has been a prominent feature of the conflict. This article examines why this has been the case. It assesses the implications of UN Security Council resolution 1820 (June 2008), which calls for internationally mediated peace talks to address conflict-related sexual violence; advances reasons why doing so may contribute to more durable peace; and outlines where specific textual references to sexual violence in peace agreements could enhance the well-being of survivors and reduce the chances of brutal and widespread sexual violence persisting in the post-conflict period. The article focuses on five types (or elements) of peace agreement: (1) early-stage agreements covering humanitarian access and confidence-building measures; (2) ceasefires and ceasefire monitoring; (3) arrangements for demobilization, disarmament and reintegration (DDR) and longer-term security sector reform (SSR); (4) post-conflict justice institutions; and (5) provisions relating to reparations for victims of serious human rights abuses.
