This legislation establishes a coordinated U.S. government approach to involving young people in peacebuilding and conflict prevention efforts worldwide. The bill designates a USAID Youth Coordinator to lead development and implementation of a comprehensive Youth, Peace, and Security Action Plan across federal agencies, requiring coordination between the State Department, Defense Department, Peace Corps, and other relevant offices. The coordinator will oversee efforts to meaningfully include youth ages 10-29 in peace negotiations, democracy programs, conflict resolution, and post-conflict recovery initiatives, with particular attention to underrepresented groups including young women and girls, LGBTQI+ youth, and youth from marginalized communities. The bill authorizes $5.5 million for a Youth, Peace, and Security Fund to provide grants and technical assistance to youth-led organizations working on peacebuilding and violence prevention. Congress must receive implementation reports starting one year after the action plan is submitted and biennially thereafter, with spending details and progress metrics made publicly available on USAID's website.
