Didessa is one of the woredas in the Oromia Region of Ethiopia. It is named after the Didessa River, a tributary of the Abay River. Part of the Illubabor Zone, Didessa is bordered on the south by the Didessa River which separates it from the Jimma Zone, and on the north by Gechi. The major town in Didessa is Denbi.
Coffee is an important cash crop of this woreda. Over 50 square kilometers are planted with this crop.[1] The proposed Didessa Wildlife Sanctuary will extend along the all-weather road from Nekemte to Bedele. The proposed area of the reserve will cover about 1,333 square kilometers containing a watershed with 14 small streams, and the habitat of about 54 plant species, 30 mammal species, and a number of birds.[2]
