Since the establishment of the Youth, Peace and Security agenda in 2015 with UN Security Council Resolution 2250,and further specific frameworks for youth inclusion in formal peace processes with UN Security Council Resolution2419 (2018), there has been growing attention on the relationship between youth peacebuilders and the institutionstasked with building peace. While the priority for the international community has been on transforming the formalspace to facilitate a more inclusive landscape, young people have been doing the work to build the foundations for peace within their communities, despite limited access to resources and heightened security threats. To date,progress toward implementing inclusive strategies remains largely conceptual within the formal peace architecture.There are calls for accelerated action from youth and their allies in areas including capacity strengthening,knowledge solutions, community of practice and partnership, and institutionalization and policy. This reportcontributes to this strategic approach by offering practical recommendations for how the international community can support and amplify the fundamental and vital peace work already being done by youth. Drawing on interviews with youth peacebuilders in Afghanistan, South Sudan and Myanmar, this report examinesthe activities, leadership, and inclusion of youth in the formal peace processes and peacebuilding work beyondinstitutional processes. Research for this report was facilitated by Search for Common Ground and undertaken by youth researchers with support from adult researchers with the aim of strengthening the evidence base on youth inclusive peace processes and demonstrating the value of youth-led research. Research for this report wasundertaken as the February 1 coup occurred in Myanmar, and before the Taliban takeover of Afghanistan in August.The insights offered by the youth peacebuilders, however, remains even more relevant and urgent, as the events of 2021 demonstrate how fragile peace can be. Continued efforts towards substantive youth-inclusive peace practices requires a commitment to greatercoordination between youth and other peacebuilding stakeholders. Cooperation must occur both within formalsystems and between formal systems and the informal spaces where youth leadership is most often found. Youthpeacebuilders in South Sudan, Afghanistan and Myanmar are united in their advocacy for peace architecture thatrecognises and supports the work they are doing to create enabling environments for sustainable peace. Strongconsensus also exists amongst youth peacebuilders around the need for equitable and substantive access to peacenegotiations and other formal processes Currently, frustrations are heightened amongst youth activists. Despite international frameworks thatobligate member states to empower youth and take their needs seriously, implementation of this mandate remains constrained by politics, power, economics and exclusionary social discourses. Youth also face threats and significant risks in undertaking their peacebuilding work and participating in formal political processes.Despite these barriers, youth peacebuilders interviewed shared a transformative and foundational vision for peace.
