DROUGHT MAY REDUCE ZIMBABWE COFFEE OUTPUT -GROWERS Zimbabwe's projected coffee output of 13,000 tonnes for 1987/88 could be reduced by drought, growers said. The main coffee growing areas in eastern Zimbabwe have received little rain since April 1986 and the Coffee Growers' Association has begun a survey to assess the effects of the drought, a spokesman said. Zimbabwe exported 11,000 tonnes of coffee in 1986, mainly to West Germany, Britain, Japan, the Netherlands, Switzerland and the United States.
