Malnutrition and related diseases are expected to rise in Zimbabwe, peaking in the January to March 2005 period, according to a new report by the Famine Early Warning Systems Network (FEWS NET). While staple cereals are increasingly unavailable in rural areas, maize prices on the parallel market continue to climb, limiting the ability of households to buy enough food to satisfy their needs, said both FEWS NET and the World Food Programme (WFP) in separate surveys.
