As part of a wider initiative for the social protection of children in post-war Bosnia and Herzegovina, UNICEF partnered with cantons and municipal governments in 2010 to establish Integrated Early Childhood Development (IECD) Centres; a situational analysis and piloting of the approach supported a sharpening of priorities and the development of practical solutions; longstanding partnerships between government actors and development agencies allowed for gradual capacity-building at the subnational level, enabling local uptake of new roles and responsibilities relating to early childhood development; aligning national policy with municipal action encouraged widespread adoption of changes, increasing consistency in approaches and securing sustainability of local efforts.
