This brief, written by a young Kenyan human rights lawyer who works in the transitional justice and international criminal law field, provides an overview and road-map of the ways that youth-centered and youth-inclusive transitional justice efforts can advance durable peace and transformative peace processes. Drawing on the recommendations and findings of the YPS Progress Study, this policy brief points to the vital gap in the inclusion and participation of young people in transitional justice initiatives – a key dimension of peace processes and sustaining peace efforts. It argues that the gap in young people’s participation and inclusion undermines the potential efficacy, legitimacy, and durability of peace processes, as well as of truth, accountability, reconciliation, and prevention efforts, and further marginalizes young people wishing to transform conflict-affected and post-conflict societies.
