Ex-Limu Kosa woreda 22 , that means current Limu Kosa and Chore Botor woredas,
lies in the northern part of Jima zone, between 7°50’ and 8°36’N, 36°44’ and 37°29’E
geographical grids. It had an area of 2,770.5 km² and has three urban centres 23 , including

the woreda lies between 1,200 and 3,020 masl. Several perennial rivers (Gibe, Awetu, Dembi,
etc.), intermittent streams, springs and Cheleleki Lake are found there. Climatically, Limu
Kosa woreda is classified into dega (10%), woïnadega (65%) and kola (25%) zones 24
