The article reports: "Food production in Zimbabwe has fallen by more than 50%, measured against a five-year average, due mostly to the current social, economic and political situation and the effects of the drought," the UN agencies [WFP and FAO] said. The underlying cause was described as "unwise policies over land redistribution."
