UN peacekeeping is a vital investment in global peace and security.The theme for this year’s Day is “Women in Peacekeeping: A Key to Peace” to help mark the 20th anniversary of the adoption of UN Security Council Resolution 1325 on Women, Peace and Security.Women peacekeepers make invaluable contributions to peacekeeping. They help improve overall peacekeeping performance, have greater access to communities, especially to women, and therefore, help in promoting human rights and protection of civilians. They also encourage women to become a meaningful part of peace and political processes; when diverse women participate in peace negotiations, the quality and durability of peace agreements increases, and when women are signatories of peace agreements, they are more likely to be implemented, which academic research shows helps to ensure sustainable peace and prosperity.
