While there has been substantial progress in reducing global poverty in recent years, hundreds of millions of vulnerable children remain trapped in extreme poverty. This is especially the case on the African continent, where children account for the majority and growing proportion of the population. Despite rapid economic growth in several African countries, as well as significant achievements in both development and humanitarian interventions, a staggering number of African children remain vulnerable to extreme levels of deprivation. Existing challenges notwithstanding, a number of social policies and programmes proved successful in alleviating the burden of child poverty and deprivation. In addition to being vitally important in promoting and protecting children's rights, these social policies and programmes embody the international community's commitment to achieve the Social Development Goals (SDGs) and ensuring no one is left behind. What Works for Africa's Poorest Children? From Measurement to Action identifies the social policies and programmes that are most effective in supporting Africa's poorest and most vulnerable children, and examines the key features underpinning their documented success. It provides cutting edge examples on how we can identify child poverty and deprivation, analyses innovative ultra-poor child sensitive programmes, and provides new public financing and governance rights suggestions for child poverty elimination.
