In a report published Friday, the U. N. Food and Agricultural Organization foresees a nearly one-quarter drop in Zim babwe’s cereal production from last year. This includes a plunge of more than 50 percent in corn yields. The report says Zimbabwe will probably need to import more than 500,000 tons of cereals this year, but has only the hard currency to purchase about one-fifth that amount.
The FAO study says the urban poor and low-income residents of southern and eastern Zimbabwe are most vulnerable to food shortages.
Zimbabwe President Robert Mugabe has described the seizure of farms as a justified protest against the ownership by whites of about a third of the country’s productive land.
The government wants to expropriate white-owned land without compensation and redistribute it to landless blacks.
