Coffee output in the two main export-growing areas of Ethiopia, Africa’s largest producer of the beans, may decline 60 percent because of drought, the United Nations said.

The lower harvest may aggravate malnutrition in southern Ethiopia’s Gedeo and Sidamo zones, where hunger is rife as a result of the drought, falling world coffee prices and higher food prices, the UN Office for the Coordination of Humanitarian Affairs said in a report today.

Production in Gedeo may fall 67 percent from a year earlier, while that in Sidamo may decline 53 percent, Tamirat Mulu, the author of the report, said in a phone interview in the capital, Addis Ababa, today.

Ethiopia exported 170,888 metric tons of coffee last year. About 35 percent of that was high-grade washed coffee and 65 percent lower quality dried coffee. Sidama and Gedeo provide about 60 percent of Ethiopia’s washed coffee, Mulu said.
