Examining the resources needed to implement Security Council Resolution 1325 at national level as well as the gains, gaps and glitches of financing the women peace and security agenda. Over the last decade the policy environment on women, peace and security has gained significant momentum. The adoption of UN Security Council Resolution 1325 in 2000, the recent adoption of subsequent resolutions 1820, 1888 and 1889 and now the development of indicators for tracking the implementation of 1325 call for a moment of reflection. Reflection on what has been invested, what has been achieved and, most importantly, what impact these investments have had on women, peace and security. This reflective process should include an assessment of the resources dedicated to the implementation of the women, peace and security resolutions. The purpose of this document is to highlight the different approaches to identify the funding for and the resources spent on the implementation of Security Council resolution 1325 at the national level. It provides an analysis of the current situation of mobilizing domestic and international financial resources for the development of the agenda on women and peace and security. It also analyzes approaches to calculating the cost of a 1325 National Action Plan, and how resources of different initiatives have been used to support the implementation of resolution 1325. It highlights good practices and lessons learned over the last ten years. It is expected that the information and examples contained in the study will support the proper accounting for the funds dedicated for the Security Council resolution 1325, to be implemented in a more effective, transparent and coherent way.
