This briefing paper summarizes the important lessons learned since 2018 by Oxfam Denmark and the wider Oxfam confederation while promoting the women, peace and security (WPS) agenda and supporting WPS programming in Burkina Faso, Colombia, Ghana, Kenya, Lebanon, Mali, Niger, the Occupied Palestinian Territory, South Sudan, Syria, Uganda, Ukraine and Yemen, including under the Danish International Development Agency (Danida) strategic partnerships. It contains practical and policy-level recommendations for international actors working on the WPS agenda in various crisis and conflict contexts globally. The briefing paper shows that supporting and amplifying locally led feminist action by diverse women-led, women’s and LGBTQIA+ rights organizations, networks and groups is a central foundation for peace and justice.
