Read the case study:

WVI Child-Friendly Spaces (CFS) Intervention at Buramino Camp, Dolo Ado, Ethiopia:

Buramino refugee camp, located along the southern Somali-Ethiopian border, was selected in cooperation with World Vision Ethiopia as the first evaluation site. At the time of the evaluation, the Ethiopian Administration for Refugee and Returnee Affairs (ARRA), the main implementing partner of UNHCR, had organised five camps within two hours of the Dollo Ado transit centre to address the growing needs of Somali refugees who had migrated in response to drought and ongoing conflict in the region. In January 2012, World Vision Ethiopia’s first Child Learning Centre (subsequently referred to through this report as a CFS site) was established, offering a range of services to children aged six to 17 years. The second CFS site started activities later that year, in May 2012. Within the wide continuum of CFS programming approaches, these two sites emphasised functional literacy and numeracy skills. Based on discussions with ARRA and parents of children attending these centres, psychosocial activities, such as drawing, singing, and recreational play, were included, but to a modest degree. On-site counselling and a feeding programme were also offered. To help meet the overwhelming demand in the camp, each centre provided two three-hour sessions for children: a morning session for younger children aged six to 11 and an afternoon session for older children aged 12 to 17. The first CFS provided services for 784 children (500 aged between six and 11 and 284 aged between 12 and 17). The second CFS site provided services for 787 children (506 aged between six and 11 and 281 aged between 12 and 17).
