The UN Security Council Resolution 1325 on Women, Peace and Security is the outcome of over a decade-long advocacy and collaborative engagement between civil society, academics and policy actors to get the international community to recognize the plight of women and girls not only in conflict situations, but also in post-war reconstruction activities. The contents of the document are built on four pillars: participation, protection, prevention, and finally relief and recovery. This paper analyses the implementation of UNSCR 1325 in Sierra Leone’s post-war reconstruction and peacebuilding processes from the end of the war in 2002 to the tenth-year anniversary of the Resolution in 2010. The researchers found that there has been an increase in women’s representation in politics and public decision-making spaces, although there is still much work to be done in this regard. Measures have been taken for the protection and safety of women, for the prevention of women and girls against sexual and gender-based violence, and for relief and recovery of women. The note concludes with recommendations for implementation of UNSCR 1325.
