Child friendly spaces (CFS) have become a widely used approach to protect and provide psychosocial support to children in emergencies. However, little evidence documents their outcomes and impacts. There is widespread commitment among humanitarian agencies to strengthen the evidence base of programming. This report summarises studies on CFS in various crises: Buramino refugee camp, Ethiopia; Rwamwanja Resettlement Centre, Uganda; Domiz Refugee Camp, Iraq; Zarqa, Jordan; Goma IDP camps, Eastern Democratic Republic of the Congo; Nabatieh, Lebanon; and the Azraq Refugee Camp, Jordan. Key conclusions of the report include: CFS can benefit children – but the extent that they do varies widely; strengthening programme quality and fit to local circumstances should be the key programming priorities; programme innovation is required to present more engaging and effective interventions for older children; and longer-term follow-up is required to document the impact of interventions on the trajectories of children’s development.
