Coffee is a major source of income for many Ethiopians

Scientists are warning that climate change poses a threat to coffee farming in Ethiopia.

Computer modelling carried out by a team at Britain's Royal Botanic Gardens concluded that almost two-thirds of Ethiopia's existing coffee plantations could become unsuitable for growing the crop by the end of the century.

But the team found that other parts of the country, at high altitudes, would be ideal and recommended early action to prevent damage to the industry, and perhaps even leading better tasting brews.
