The document summarizes a program called Capacity Building in Conflict Cities that aimed to strengthen the capacity of youth and municipal leaders in six cities (Addis Ababa, Asmara, Freetown, Kigali, Kabul, and Nablus) to deliver services to vulnerable youth and children. The program involved city-to-city partnerships and exchanges to share best practices. It established One Stop Child and Youth Centers in each city led by trained local youth to provide activities and education in nutrition, ICT, health, sports, and arts for at-risk youth. The program underwent two phases, with the first focusing on exchanges between partner cities and the second on additional local capacity building in three cities.
