This report has been developed by DCAF, the Geneva Centre for Security Sector Governance, at the request of the Security Sector Reform Unit (SSRU) of the United Nations Department of Peace Operations. The report presents the findings of a multi-year research project aimed at mapping and analysing Security Council mandates on defence sector reform and the Secretary-General Reports reporting on their implementation.

This research project has been developed as part of the broader formal review of the UN Policy on Defence Sector Reform (2011) that the SSR Unit is leading in coordination with the UN Inter-Agency SSR Task Force. Based on the findings of the review, the report has issued a set of recommendations for members of the UN Security Council, staff of the UN Secretariat, and for the Policy review process more specifically.
