For societies that depend on agriculture, the process of meeting current or future welfare demands should not continue without regard to the potential long-term dangers of land resource over-use. With an increasing human and animal population in the Ethiopian highlands development efforts so far ...


Mohamed-Saleem, M.A.[Fragile East African highlands: A development vision for smallholder farmers in the Ethiopian highlands]Fragile East African highlands: A development vision for smallholder farmers in the Ethiopian highlands

Summarises the results of on-farm research conducted by the Highlands Programme (ILCA) in order to improve smallholder livestock productivity in the Ethiopian Highlands. Outlines the farming system around Debre Berhan. Discusses on farm trials and research activities on the integration of crossbr...


Gryseels, GuidoAnderson, F.M.Asamenew, G.Mesgina, A.Astatke, A.Wolde-Mariam, W.A.[On-farm research to improve smallholder livestock productivity in the Ethiopian highlands]On-farm research to improve smallholder livestock productivity in the Ethiopian highlands

In Ethiopia vertisols of the highlands are vast and underutilized. For increasing production on highland vertisol, a joint vertisol project undertook a range of integrated research activities. ILCA's research in this partnership project, the integrated research activities, the research approach, ...


Asamenew, G.Tedla, A.[Research on crop and livestock intensification on small farm vertisols: ILCA's experience]Research on crop and livestock intensification on small farm vertisols: ILCA's experience

The impact of grazing on physical properties of Vertisol was studied from 1996 to 2000 in the Ethiopian highlands. The study was conducted at two sites with 0-4 % and 4-8 % slopes at Tero Jemjem watershed in Ginchi, 80 km west of Addis Ababa. The main objective of this work was to study effect of...


Hailemariam, A.[Effect of livestock grazing on soil micro-organisms of cracking and self mulching vertisol]Effect of livestock grazing on soil micro-organisms of cracking and self mulching vertisol

Most soils in sub-Saharan Africa are P deficient, but the high cost of water-soluble P fertilizers limits the use of P fertilizers by resource-poor farmers. A low-cost alternative is to apply phosphate rocks. We evaluated the effectiveness of unacidulated (PR), 25 percent partially acidulated (PA...


Haque, I.Lupwayi, N.Z.Ssali, H.[Agronomic evaluation of unacidulated and partially acidulated Minjingu and Chilembwe phosphate rocks for clover production in Ethiopia]Agronomic evaluation of unacidulated and partially acidulated Minjingu and Chilembwe phosphate rocks for clover production in Ethiopia

Poor drainage of Vertisols in the Ethiopian mid-altitude highlands limits farming operations and cropping in the early rainy season. Thus, traditional crops are grown late in the season on the residual moisture in the dry season when waterlogging is less of a problem. Consequently performance of ...


Tedla, A.Sherington, J.Mohamed-Saleem, M.A.[Integration of forage and food crops grown sequentially on Vertisols under rainfed conditions in the mid-altitude Ethiopian highlands]Integration of forage and food crops grown sequentially on Vertisols under rainfed conditions in the mid-altitude Ethiopian highlands

The paper first discusses the need for moving from disciplinary to transdisciplinary research in addressing problems of human development and environmental management. Then the experience of a research project in highland Ethiopia is described. This started with disciplinary research and componen...

The impact of grazing on physical properties of Vertisol was studied from 1996 to 2000 in the Ethiopian highlands. The study was conducted at 2 sites with 0-4 and 4-8% slopes at Tero Jemjem watershed in Ginchi, 80 km west of Addis Ababa. The objective of the study was to compare selected soil phy...

Animal traction has been an integral part of most agricultural systems in Ethiopia for thousands of years. There is evidence that cattle were first used for ploughing in the latter part of the third millennium BC (Goe and Astatke, 1989). Today, the traditional cattle economy is directed mainly to...


Astatke, A.Mohamed-Saleem, M.A.[Draught animal power for land-use intensification in the Ethiopian highlands]Draught animal power for land-use intensification in the Ethiopian highlands

Although the majority of soils in Africa are P deficient, the high cost of conventional water-soluble P fertilizers limits their use by resource-poor farmers. Rockphosphates are a low-cost alternative. The effect of Egyptian rockphosphate (ERP) from two sources, applied at 50 kg P ha-1, on annual...
