Degradation of crop and grazing lands is a pervasive problem that negatively impacts agricultural productivity and livelihoods of crop-livestock farmers in the Blue Nile basin of Ethiopia. Area enclosure together with a cut and carry livestock feeding system is often advocated as an approach for ...

Restoration of grazing land to increase biomass production and improve soil properties in the Blue Nile Basin: effects of infiltration trenches and Chloris gayana reseeding
Ethiopia is often highlighted as a country in which a lot of foreign land acquisition is occurring. The extent to which these investments also constitute significant acquisitions of water is the subject of this paper. It is apparent that water availability is a strong driver of the recent surge o...

Water implications of foreign direct investment in Ethiopia's agricultural sector.
Land degradation is one of the major problems related to low productivity in Ethiopia. Vertisols are potential agricultural lands but are underutilized due to waterlogging during the rainy season and are prone to soil erosion due to the traditional practices of planting crops at the end of the ra...

Technical and economic performance of animal-drawn implements for minimum tillage: Experience on Vertisols in Ethiopia
In Ethiopia, Vertisols which are affected by water logging during the rainy season due to its physical and chemical characteristics are potential agricultural lands but are prone to soil erosion. The soil erosion rates of the cultivated Vertisols are accelerated due to the traditional practices o...

The study was conducted in three watersheds (Dapo, Meja and Mizewa) in the Ethiopian part of the Blue Nile Basin to estimate the on-site cost of soil erosion using the productivity change approach, in which crop yield reduction due to plant nutrients lost with the sediment and runoff has been ana...

Linking soil erosion to on-site financial cost: lessons from watersheds in the Blue Nile Basin
Rainfed agriculutre in Ethiopia is constrained by temporal and spatial variations in climate and severe land degradation caused by soil erosion that is exacerbated by lack of appropriate technologies. The continued shrinking per capita agriculutral land due to population growth and diminishing la...

Soil fertility depletion is among the major impediments to sustained agricultural productivity especially in the less developed countries because of limited application of fertilizers. Soil fertility maintenance requires a balanced application of inorganic and organic nutrient sources. This study...

Agronomic and economic efficiency of manure and urea fertilizers use on vertisols in Ethiopian highlands
In the highlands of Ethiopia, tillage methods and frequency affect drainage, soil erosion, moisture conservation, weeding and harvesting of crops. This is through their effects on soil physical, chemical and biological qualities. In this study, four tillage methods for land preparation, "broad be...

Waterlogging is a challenge to wheat (Triticum durum Desf.) productivity under the rainfed system on Vertisols in the Ethiopian Highlands. However, using suitable seedbed types and manipulating planting dates can minimize the effects. A four-year (2000-2003) field experiment was conducted to eval...

Using a production function, marginal productivity of farm inputs and benefit-cost analysis, we explore the economics of selected water control technologies. From the production function, all farm inputs, including irrigation water is found to have a significant and positive effect on yield. Marg...
