In Mali, Niger and Chad, 40% of children under five suffer from stunting. These children do not receive enough nutrients. Their bodies — their brains, bones and muscles — do not get enough calcium, iron or zinc or enough vitamins (A, B2, B12 etc.), so they do not have enough energy to grow and develop. Many of these children will suffer from chronic diseases and will have cognitive problems — so they won’t be able to go to school for long, if at all. As adults, they will have little chance to flourish and, secondarily, will have low economic productivity. Many will also die very young, often before turning five.
