Gomma is one of the woredas in the Oromia Region of Ethiopia. It is named after the former Kingdom of Gomma, whose territory was roughly the same as the modern woreda. Part of the Jimma Zone, Gomma is bordered on the south by Seka Chekorsa, on the southwest by Gera, on the northwest by Setema, on the north by the Didessa River which separates it from the Illubabor Zone, on the northeast by Limmu Kosa, and on the east by Mana. Towns include Beshasha, Choche, Ghembe, and Limmu Shaye. Guma woreda was separated from Gomma.
The altitude of this woreda ranges from 1,380 to 1,680 meters above sea level; however, some points along the southern and western boundaries have altitudes ranging from 2229 to 2870 meters. A survey of the land in this woreda shows that 60.7% is arable or cultivable (52.7% was under annual crops), 8.1% pasture, 4.6% forest, and the remaining 20.1% is considered swampy, mountainous or otherwise unusable. Land in cultivation included the two state coffee farms. Fruits, avocadoes and spices are important cash crops.
Coffee is also an important cash crop in Gomma; over 50 square kilometers are planted with this crop. Coffee is grown in this woreda under shade trees; while the dominant species are Albizia gummifera, which can shade as many as 150 coffee trees, and Millettia ferruginea, other species are also used as shade trees.
Industry in the woreda includes 118 grain mills, 35 coffee hulling and 33 coffee pulping mills, one sawmill, an office and furniture factory, and one edible oil mill. There were 45 Farmers Associations with 45,226 members and 21 Farmers Service Cooperatives with 43,088 members. One micro-finance institution operates in this woreda: the Oromiyaa Credit and Saving SC (OCS), established in 1997; its branch in Gomma was one of the first the OCS opened. While mismanagement forced the OCS to close that branch within the year, it was reopened in 2001 and serves customers in Agaro and 17 of the 39 kebeles. Gomma has 55 kilometers of dry-weather and 89 all-weather road, for an average of road density of 117 kilometers per 1,000 square kilometers. About 41% of the urban and 15.9% of the rural population has access to drinking water.
