The great concentration of human population between 2 600-2 800 m above sea level in this part of Ethiopia suggests the availability of flat and ondulating topography at that altitude. Cattle are also found more at these elevations; lower altitudes
Glacial and periglacial phenomena in Ethiopia : a review

The glacial and periglacial geomorphology for the Simen and Bale Mountains in Ethiopia is reviewed. The Simen Mountains are mostly absent of relict perglacial landforms and today host a variety of miniature cryogenic phenomena. The Bale Mountains
host a few localized large relict cryogenic landforms (e.g. stone stripes), suggesting past sporadic permafrost. A variety of regional factors may have contributed to the more extensive periglacial activity in southern Ethiopia than in the higher Simen
Age of volcanism and rifting in southwestern Ethiopia
Field data and K-Ar isotopic ages from southwestern Ethiopia indicate that volcanism in this area began earlier than previously suspected, and that Quaternary volcanism was not restricted to the axial zone. That major rifting in this region did
Hominid occupation of the east-central highlands of Ethiopia in the Plio-Pleistocene
Stone artefacts and fossil evidence suggest that hominids did not reach the high plateau of Ethiopia until1.5 Myr ago. Contact between hominids of the plateau and the Rift Valley seems likely.
This paper investigates the performance of selected soil and water conservation measures in the highlands of Ethiopia and Eritrea, namely Fanya Juu, soil/stone bund, grass strips and double ditches. The impact of these techniques on runoff, soil

The paper examines the case of local community based institutions involved in wetland management in western Ethiopia. Drawing upon the findings of participatory fieldwork undertaken in eight communities, it is argued that although local institutions
Paleoenvironmental changes during the last 4000 yr in the Tigray, Northern Ethiopia
C 14 dating ; Ethiopia ; Geochronology ; Holocene ; Land use ; Palaeo-environment ; Palaeoclimate ; Stratigraphy ; Thermoluminescence
In this study, a high-resolution sequence of the main degradational and stability phases during the past 4000 yr in Northern Ethiopia, and in the Ethiopian Highlands in general, is presented. The paleoenvironmental reconstruction involved the use
Reservoir siltation in the semi-arid highlands of northern Ethiopia : sediment yield-catchment area relationship and a semi-quantitative approach for predicting sediment yield
Reservoir surveys were conducted to estimate sediment deposition rate for 11 reservoirs identified to be representative of catchments in the Tigray region of northern Ethiopia. Field surveys were conducted to characterize the catchments in terms
of erosional susceptibility based on factorial scoring approach. Finally, the factorial index was integrated with the catchment area to develop a semi-quantitative sediment yield potential prediction model for the highlands of northern Ethiopia.
