There are fears of a looming food shortage in Burundi after heavy rains damaged two successive harvests, say officials. 'More than half of the expected harvest was lost in flooding and siltation,' Methode Niyongendako, a consultant with the UN Food and Agriculture Organization (FAO), said. The rains peaked in mid-September and November, exceeding forecasts in terms of volume and frequency, and were the heaviest since October 1961, according to households questioned, added Niyongendako.
