Ex-<strong>Limu</strong> Kosa woreda 22 , that means current <strong>Limu</strong> Kosa and Chore Botor woredas,<br />

geographical grids. It had an area of 2,770.5 km² and has three urban centres 23 , including<br />
<strong>Limu</strong> Genet, the district’s capital. It is bordered <strong>on</strong> the south by Kersa woreda, <strong>on</strong> the<br />

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