This article presents the findings of a study undertaken to assess environmental impacts of two selected large scale irrigation schemes on natural resources in Ethiopia. The study puts special emphasis on linkages and implications of the utilized water source, ground water hydrology and soil char...

The discharge of the Nile River is highly dependent on the flow generated in the highlands of Ethiopia. However, little is known about the local (i.e. small scale) watershed hydrological response, due in part to a lack of long duration, continuous hydrological data. The goal of this paper was to ...


Collick, A.S.Easton, Z.M.Ashagrie, T.Biruk, B.Tilahun, S.Adgo, E.Awulachew, Seleshi BekeleZeleke, G.Steenhuis, Tammo S.[A simple semi-distributed water balance model for the Ethiopian highlands]A simple semi-distributed water balance model for the Ethiopian highlands

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...

Ethiopia has an irrigation potential of 5.3 million ha (Mha) of which 3.7 Mha can be developed using surface water sources, and 1.6 Mha using groundwater and rainwater management. Irrigation contributes to rapid transformation of agriculture as present-day agriculture is dominated by rainfed sing...

Unless attention is given to productivity improvements in food production, feeding the ever-increasing population persist to be the challenge for Ethiopia. The hope that irrigation development improves the productivity of agriculture, ensures food security, overcome impacts of rainfall variabilit...

The main focus of this article is to explore whether access to selected agricultural water management (AWM) technologies has led to significant reduction in poverty and, if they did so, to identify which technologies had higher impacts. In measuring impact we estimated the average treatment effec...

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...

With its an estimated human population of 85 million which increases annually at about 2.7 per cent, Ethiopia is the second most populous country in Sub-Saharan Africa (SSA) only after Nigeria. Agriculture contributes about 45% and 85% to the GDP and the export earnings, respectively. However, ag...

This paper provides study results of irrigation in Ethiopia. Broad performances criteria for national and regional levels of irrigation are established. The national performance according to functioning schemes, command area size and number of beneficiaries as compared to design targets are 87%, ...

This paper provides an overview of poverty levels, hydrology, agricultural production systems and water productivity in the Nile Basin. There are opportunities to manage water better in the basin for use in agriculture to improve food security, livelihoods and economic growth by taking into accou...
