Agricultural intensification to meet the food needs of the rapidly growing population in developing countries is negatively affecting the water quality. In most of these countries such as Ethiopia, information on surface and especially groundwater quality is lacking. This limits the measure that ...

Restoration of degraded landscapes through the implementation of soil and water conservation practices is considered a viable option to increase agricultural production by enhancing ecosystems. However, in the humid Ethiopian highlands, little information is available on the impact of conservatio...


Akal, Adugnaw T.Dagnew, D.C.Belete, M.A.Tilahun, Seifu A.Mekuria, Wolde M.Steenhuis, Tammo S.[Impact of soil depth and topography on the effectiveness of conservation practices on discharge and soil loss in the Ethiopian Highlands]Impact of soil depth and topography on the effectiveness of conservation practices on discharge and soil loss in the Ethiopian Highlands

Intensification of rainfed agriculture in the Ethiopian highlands has resulted in soil degradation and hardpan formation, which has reduced rooting depth, decreased deep percolation, and increased direct runoff and sediment transport. The main objective of this study was to assess the potential i...


Hussein, Misbah A.Muche, HabtamuSchmitter, PetraNakawuka, ProssieTilahun, Seifu A.Langan, SimonBarron, JennieSteenhuis, Tammo S.[Deep tillage improves degraded soils in the (sub) humid Ethiopian highlands]Deep tillage improves degraded soils in the (sub) humid Ethiopian highlands

Water resources in sub-Saharan Africa are more overstressed than in many other regions of the world. Experiments on commercial farms have shown that conservation agriculture (CA) can save water and improve the soil. Nevertheless, its benefits on smallholder irrigated farms have not been adequatel...


Belay, Sisay A.Schmitter, PetraWorqlul, A.W.Steenhuis, Tammo S.Reyes, Manuel R.Tilahun, Seifu A.[Conservation agriculture saves irrigation water in the dry monsoon phase in the Ethiopian highlands]Conservation agriculture saves irrigation water in the dry monsoon phase in the Ethiopian highlands

In the northern highlands of Ethiopia, gully erosion is severe. Despite many efforts to implement gully prevention measures, controlling gully erosion remains a challenge. The objective is to better understand the regional gully erosion processes and to prevent gully head retreat. The study was c...


Addisie, Meseret B.Ayele, Getaneh K.Gessess, A.A.Tilahun, Seifu A.Zegeye, Assefa D.Moges, M.M.Schmitter, PetraLangendoen, E.J.Steenhuis, Tammo S.[Gully head retreat in the sub-humid Ethiopian Highlands: the Ene-Chilala Catchment]Gully head retreat in the sub-humid Ethiopian Highlands: the Ene-Chilala Catchment

Land use and management affects runoff and soil loss from a catchment. The present study investigated the effects of land use on runoff and suspended sediment concentration and yield in the northwestern Ethiopia. We selected two small catchments: cultivated land and grassland dominated catchments...


Dagnew, D.C.Guzmán, C.D.Akal, Adugnaw T.Tebebu, T.Y.Zegeye, Assefa D.Mekuria, Wolde M.Tilahun, Seifu A.Steenhuis, Tammo S.[Effects of land use on catchment runoff and soil loss in the sub-humid Ethiopian highlands]Effects of land use on catchment runoff and soil loss in the sub-humid Ethiopian highlands

The Ethiopian government has been implementing a land restoration program that aimed to restore degraded ecosystems and double agricultural productivity throughout the country since 2010. However, the success of the restoration program has been limited due to the lack of integrating gully erosion...


Zegeye, Assefa D.Steenhuis, Tammo S.Mekuria, Wolde M.Dagnaw, D.C.Addisse, M.B.Tilahun, Seifu A.Kasse, T.A.[Effect of gully headcut treatment on sediment load and gully expansion in the sub humid Ethiopian Highlands]Effect of gully headcut treatment on sediment load and gully expansion in the sub humid Ethiopian Highlands

Purpose - Agricultural intensification to meet the food needs of the rapidly growing population in developing countries affects water quality. In regions such as the Lake Tana basin, knowledge is lacking on measures to reduce non-point source pollutants in humid tropical monsoon climates. The aim...

Planning effective landscape interventions is an important tool to fight against land degradation and requires knowledge on spatial distribution of runoff. The objective of this paper was to test models that predict temporal and spatial distribution of runoff. The selected models were PED-WM, HBV...


Moges, M.A.Schmitter, Petra S.Tilahun, Seifu A.Langan, Simon J.Dagnew, D.C.Akal, Adugnaw T.Steenhuis, Tammo S.[Suitability of watershed models to predict distributed hydrologic response in the Awramba Watershed in Lake Tana Basin]Suitability of watershed models to predict distributed hydrologic response in the Awramba Watershed in Lake Tana Basin

Controlling soil erosion is important for maintaining land productivity and reducing sedimentation of reservoirs in the Ethiopian highlands. To gain insights on sediment loss patterns, magnitude of peak sediment events, and their contribution to annual loads, hydrometric and sediment concentratio...


Dagnew, D.C.Guzmán, C.D.Zegeye, Assefa D.Akal, Adugnaw T.Moges, M.A.Tebebu, T.Y.Mekuria, Wolde M.Ayana, Essayas K.Tilahun, Seifu A.Steenhuis, Tammo S.[Sediment loss patterns in the sub-humid Ethiopian Highlands]Sediment loss patterns in the sub-humid Ethiopian Highlands
