The Agenda is implemented in each State party, on the basis of a national implementation plan, guided by the overall Action Plan, for each implementation phase. The end dates of each of the five implementation phases are 2020, 2025, 2030, 2035 and 2040. Each State party reports to the African Children’s Committee at the end of each phase. Implementation should be aligned with States’ other international obligations and commitments AU member States should align their national implementation plans and the various Action Plans with their commitments and obligations under AU Agenda 2063, the SDGs and other international treaties.

The AU’s political engagement should target these States. As far as under-5 mortality is concerned, in 2013, ten sub-Saharan African States had a rate of above 100 per 1 000 live births. This group includes five countries emerging from or experiencing conflict (Angola, the Central African Republic, the Democratic Republic of the Congo (DRC), Sierra Leone and Somalia); and five other States (Chad, Guinea-Bissau, Mali, Niger and Nigeria). The latter five States, in particular, should be targeted and supported with capacity building, the development of programmes, and donor support. As far as child marriage is concerned, the two countries with the highest prevalence of child marriages (as a percentage of women between the ages of 20 and 24 years who were first married or in union before they were 18 years old) are in Africa, namely, Niger (with 76 per cent) and the Central African Republic (with 68 per cent).
