Sherka is one of the Aanaas in the Oromia Regional State of Ethiopia. Research by Ulrich Braukämper uncovered a local tradition that traced the origins of this woreda's name to an ancient Ethiopian province, Sharkha, which vanished as a political unit in the 16th century.[1] Part of the Arsi Zone, Sirkaa is bordered on the south by the Shebelle River which separates it from the Bale Zone, on the southwest by Bekoji, on the west by Digeluna Tijo, on the north by Tena, and on the east by Robe. Gobesa is the administrative center; other towns include Gaadoo Gunaa.
The altitude of this woreda ranges from 350 to 1350 meters above sea level. Perennial rivers include 25 kilometers of the Gumelo and 20 of the Rapese. A survey of the land in this woreda shows that 21.4% is arable or cultivable, 6.3% pasture, 2.7% forest, and the remaining 69.6% is considered swampy, mountainous or otherwise unusable. Pepper, black and white cumin and fenugreek are important cash crops.[2]
