Seweyna is one of the woredas in the Oromia Region of Ethiopia. Located in the eastern part of the Bale Zone, Seweyna is bordered on the south by Raytu, on the southwest by Ginir, on the northwest by Gaserana Gololcha, on the north by Legehida, and on the east by the Somali Region. Towns in Seweyna include Hada.
The geography of this woreda is characterized by a dry plain in the western part and lowland in the east marked by low escarpments, flood plains and lava flows. Elevations extend from 400 to 1850 meters above sea level. Major rivers include the Mekenisa, Dare, Manduba and Kurkura. A survey of the land in this woreda shows that 24.4% is arable or cultivable, 46.3% pasture, 24.1% forest or heavy vegetation, and the remaining 5.2% is considered degraded, mountainous or otherwise unusable. Corn, sorghum, wheat and teff are important local crops. Raising livestock is another important source of food and income, which include in order of importance shoats, camels and cattle; during the months of May and June, inhabitants of the western kebeles who rely more on raising crops, collect and consume a wild fruit called kulkal (known locally as Shonka). Seweyna is considered a chronically food insecure woreda, and food aid is received irrespective of their income levels.
Industry in the woreda includes 2 grain mills created with funding from the Regional government, as well as one wholesaler and 18 retailers. There were 19 Farmers Associations with 7750 members and no Farmers Service Cooperatives. Seweyna has no kilometers of road. About 10% of the total population has access to drinking water.
