Geografio de Somalio: Malsamoj inter versioj
Ĉefe en la plej arida orienta parto de Ogo, la ebenaĵo kun kelkaj izolitaj montoj laŭgrade deklivas al la [[Hinda Oceano]] kaj en centra Somalio konstituas la ebenaĵon de [[Mudugo]]. Plej grava eco de tiu orienta sektoro estas la longa kaj larĝa valo de [[Nugaal]], kun sia reto de sezonaj akvofluoj aŭ ''gvadioj'' aŭ ''ŭadioj''. La rivero Nugaal enfluas en la [[Hinda Oceano]] ĉe [[Eyl]]. La populacio de la orienta areo konsistas ĉefe el paŝtistaj nomadoj.
The Haud zone continues for more than sixty kilometers into Ethiopia, and the vast Somali Plateau, which lies between the northern Somali mountains and the highlands of southeast Ethiopia, extends south and eastward through Ethiopia into central and southwest Somalia. The portion of the Haud lying within Ethiopia was the subject of an agreement made during the colonial era. In 1948, under pressure from their World War II allies and to the dismay of the Somalis,<ref name="Federal">Federal Research Division, ''Somalia: A Country Study'', (Kessinger Publishing, LLC: 2004), p.38</ref> the British "returned" the Haud (an important Somali grazing area that was presumably 'protected' by British treaties with the Somalis in 1884 and 1886) and the [[Ogaden]] to Ethiopia, based on a treaty they signed in 1897 in which the British ceded Somali territory to the Ethiopian Emperor [[Menelik]] in exchange for his help against plundering by [[Somali clan]]s.<ref>David D. Laitin, ''Politics, Language, and Thought: The Somali Experience'', (University Of Chicago Press: 1977), p.73</ref> Britain included the [[proviso]] that the Somali nomads would retain their autonomy, but Ethiopia immediately claimed sovereignty over them.<ref name="Zolberg">Zolberg, Aristide R., et al., ''Escape from Violence: Conflict and the Refugee Crisis in the Developing World'', (Oxford University Press: 1992), p.106</ref> This prompted an unsuccessful bid by Britain in 1956 to buy back the Somali lands it had turned over.<ref name="Zolberg"/> The stretch of land has since been a considerable source of regional strife.
Southwestern Somalia is dominated by the country's only two permanent rivers, the [[Jubba River|Jubba]] and the [[Shabele River|Shabele]]. With their sources in the Ethiopian highlands, these rivers flow in a generally southerly direction, cutting wide valleys in the Somali Plateau as it descends toward the sea; the plateau's elevation falls off rapidly in this area. The adjacent coastal zone, which includes the lower reaches of the rivers and extends from the Mudug Plain to the [[Kenya]]n border, averages 180 meters above sea level.
