Ano: 2008 URL: http://purl.umn.edu/118411 A comparative analysis of the technical efficiency of rain-fed and smallholder irrigation in Ethiopia AgEcon Makambe, Godswill; Namara, Regassa E.; Hagos, Fitsum; Awulachew, Seleshi Bekele; Ayana, Mekonnen; Bossio, Deborah A.. Agriculture is the most significant contributor to Ethiopia’s economy. Most of the agricultural production is under rainfed conditions and thus extremely sensitive to rainfall variability. Irrigation development, including smallholder irrigation, is used by the Ethiopian Government to attempt to mitigate the effects of rainfall variability. In this study, we look at smallholder irrigation - modern and traditional irrigation systems. A detailed description of the cropping patterns is given. The stochastic frontier production function approach is used to estimate technical inefficiency, and constraints to production are analyzed. Since the traditional system is found to be efficient but on a lower production frontier, the study shows that significant gains...

Ano: 2011 URL: http://purl.umn.edu/113012 Evaluation of current and future water resources development in the Lake Tana Basin, Ethiopia AgEcon McCartney, Matthew P.; Alemayehu, Tadesse; Shiferaw, Abeyu; Awulachew, Seleshi Bekele. Lake Tana, located in the headwaters of the Blue Nile, is valuable for many people including the communities who live around the lakeshore and those who live immediately downstream. The area has been identified as a region for hydropower and irrigation development, vital for economic growth in Ethiopia. A multidisciplinary study was conducted to assess the possible impacts of this development. This study found that current development has benefited some local people but adversely affected others. Future development will exacerbate pressure on the lake. Hard choices must be made about how the water is best utilized. It is important that all stakeholders, including local people, are involved in the decision-making process.

Ano: 2008 URL: http://purl.umn.edu/118410 Importance of irrigated agriculture to the Ethiopian economy: Capturing the direct net benefits of irrigation AgEcon Hagos, Fitsum; Makombe, Godswill; Namara, Regassa E.; Awulachew, Seleshi Bekele. Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation...

Ano: 2009 URL: http://purl.umn.edu/118388 Institutional settings and livelihood strategies in the Blue Nile Basin: Implications for upstream/downstream linkages AgEcon Haileslassie, Amare; Hagos, Fitsum; Mapedza, Everisto; Sadoff, Claudia W.; Awulachew, Seleshi Bekele; Gebreselassie, Solomon; Peden, Don. Through rapid assessment of existing literature and review of policy and other official documents, the report synthesizes the existing knowledge and gaps on policies and institutions and identifies key research issues that need in-depth study. The report provides an overview of the range of key livelihoods and production systems in the Blue Nile Basin (BNB) and highlights their relative dependence on, and vulnerability to, water resources and water-related ecosystem services. It also makes an inventory of current water and land related policies and institutions in the BNB, their organizational arrangements, dynamics and linkages and key policy premises. It highlights the major problems in institutional arrangements and policy gaps and makes suggestions for...
