Measuring Cost of Hunger in Africa (COHA) study:  Mauritania is among the third-phase countires (Cameroon, Botswana, Kenya, Mauritania) to implement the COHA study. The overarching objective of the multi-country study led by the AUC, NEPAD, WFP and UNECA, is to catalyse coordinated action and inform the design of nutrition-oriented policy frameworks and programmes, with greater investments to eradicate child undernutrition on the continent.
