The growing region Sidamo is located in the south of the country at the edge of the Ethiopian Highlands. Similarly to the other Ethiopian regions, coffee is cultivated in small peasant structures. Another well-known coffee region in Ethiopia is Harar, one of the highest growing regions worldwide. Ethiopia, the former Abyssinia, is known as the birthplace of coffee. Descendants of the oldest coffee plants were found in the Ethiopian Highlands. Today, the country is the most important exporter of Arabica. Some 12 million Ethiopians earn their living by growing coffee on mostly small plantations.
