Hunger, undernourishment, and malnutrition rates for Zambia have been reported in different publications as being extremely high and among highest rates in the world. The most recent statistics on undernourishment by Food and Agriculture Organisation (FAO), International Fund for Agricultural Development (IFAD) and World Food Programme (WFP) (2014) ranked Zambia as having the highest levels in Africa and second from the bottom in world at 48%, a figure which is projected for 2014 to 2016. The MoA, is among key stakeholders, which have queried these statistics given that Zambia recently experienced back to back surpluses in maize production which provides 70 percent energy supply requirement. This technical paper reviews the status of undernourishment, hunger and malnutrition in Zambia, examining how the rates have been calculated. It also explains the likely causes of the high rates of hunger and malnutrition in Zambia.
