Effects of land use and land cover on sheet and rill erosion rates in the Tigray highlands, Ethiopia
- Effects of land use and land cover on sheet and rill erosion rates in the Tigray highlands, Ethiopia
- The AA. conducted runoff plot experiments in the semi-arid north Ethiopian Tigray highlands to investigate whether erosion rates are within the same order of magnitude as the rates observed in central, east and south Ethiopia, to measure the effects
- This study makes a multi-scale assessment over a time span of 30 years of environmental rehabilitation in one of the world's most degraded areas : the Tigray highlands. It study shows that in Tigray sheet and rill erosion rates have decreased
- investigations. The positive changes in ecosystem service supply that result from these conservation activities in the Tigray highlands are an issue of global concern.
- Specific sediment yield in Tigray-Northern Ethiopia : assessment and semi-quantitative modelling
- Sediment deposition in reservoirs is a serious off-site consequence of soil erosion in Tigray. Field rating of catchment characteristics and the sediment yield data from the reservoir survey were used for calibration and validation of the models

- By the example of Tigray/Ethiopia this contribution demonstrates the importance of the multi-proxy colluvial deposit, while emphasising it's suitability for geoarchaeological and palaeopedological research. The analysis of colluvial deposits

- 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

- The AA. evaluated the performance of 2 micro dams in Tigray by analyzing rainfall characteristics, surface water inflows and combined evaporation and seepage losses. Given the scarcity of reliable meteorological stations, transfer of rainfall data
- This paper presents the case of a natural rock fragment (RF) mulch whose lithology indicates that the RF are up-squeezed by the local vertisol. Based on the data from the experimental site located in the pass of Enda Maryam, Tigray, Northern

- This paper analyses the factors that control rates and extent of soil erosion processes in the May Zegzeg catchment near Hagere Selam in the Tigray Highlands. Soil loss rates due to various erosion processes, as well as sediment yield rates
- of Tigray. This analysis gives evidence of important environmental changes in the surrounding area, from the early Holocene to the present.
- of rock fragment cover along catenas, and the vertical variations in volumetric rock fragment content in soil profiles in the highlands of Tigray, northern Ethiopia. Natural and anthropogenic processes inducing these patterns are assessed.
- seeds in the bare inter-plant areas; and that seeds in the latter are more likely to be translocated by runoff to microsites under shrubs than to other open areas. The study area is located in the Geba river catchment, central Tigray, northern Ethiopia.
- In the May Zeg-Zeg catchment in Tigray, north Ethiopia, integrated catchment management has been implemented since 2004 : stone bunds were built in the whole catchment, vegetation was allowed to re-grow on steep slopes and other marginal land
- . Sediment yield was also measured at the catchment's outlet. This diachronic comparison of sediment budgets revealed that integrated catchment management is the way to combat land degradation in Tigray and other tropical mountains.
