The Women, Peace and Security (WPS) agenda and women's participation in peace processes are strongly supported by states. Yet financing to support the implementation of WPS has lagged behind overt international commitments to the agenda. WPS scholars and practitioners have highlighted the funding shortfalls for enabling WPS implementation and continued under-investment in gender-inclusive peace. In this article, we ask how much are donor states financially backing the implementation of gender-inclusive peace agreements which they promote? We use a high ambiguity-conflict model of policy implementation to explore the mechanisms of bilateral and multilateral financing for gender-inclusive peace. We trace to what extent international investments are supporting specific gender provisions in two progressive gender-inclusive peace processes, the 2016 Colombian Peace Agreement and 2015 Comprehensive Peace Agreement in the Philippines. In both case studies, we reveal a drastic gap between the international donor rhetoric and the funding. Patterns of financial investment do not follow nor support the life cycle of inclusive peace processes. We suggest key strategies for further research to address this policy and recommend that all gender provisions of peace agreements be monitored in-country and all gender-responsive investments be tracked and evaluated.
