More than 200 million children under the age of five in the developing world are at risk of not reaching their full development potential because they suffer from the negative consequences of poverty, nutritional deficiencies and inadequate learning opportunities (Lancet 2007). In addition, 165 million children (one in four) are stunted, with 90 percent of those children living in Africa and Asia (UNICEF et al, 2012). And while some progress has been made globally, child malnutrition remains a serious public health problem with enormous human and economic costs. Child death is a tragedy. At 6 million deaths a year, far too many children perish before reaching the age of five, but the near certainty that 200 million children today will fall far below their development potential is no less a tragedy.
