This book was released on 2018-09-27 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rate of global increase in water abstraction for irrigation has been declining since the 1970's due to declining potentials for large and medium-scale irrigation developments, and is expected to further decline in the next decades. As such the significant proportion of the expected increase in production would have to be supplied from existing irrigated and /or cultivated lands. This in turn could be achieved by enhancing land and water productivity through improved performance and optimal operation and maintenance. With less than 15% of over 5 million ha irrigation potential harnessed, irrigation devolvement in Ethiopia remained low. Over 70% of the developed irrigation in the country belongs to small-scale irrigation serving smallholder farmers. While accelerated development of new irrigation, particularly of large and medium-scale schemes is relevant in Ethiopia, ensuring the performance and sustainability of existing schemes is also equally important. The existing irrigation schemes in Ethiopia are generally characterized by an overall performance and technical sustainability levels of below expectation. This thesis evaluates the performance of two large-scale (Wonji-Shoa and Metahara) and two community-managed (Golgota and Wedecha) irrigation schemes located in the Awash River Basin of Ethiopia. The study focussed on hydraulic/water delivery performance in the large-scale schemes, and on comparative and internal irrigation service (utility) evaluation in the community-managed schemes. Water delivery performance was evaluated using routine data and hydrodynamic modelling. Farmers' utility was evaluated using qualitative responses of water users. Major performance challenges in each category of schemes were addressed and operational/water management options for improvement were identified.

Download or read book A Comparative Analysis of the Technical Efficiency of Rain-fed and Smallholder Irrigation in Ethiopia written by Makombe, G. and published by IWMI. This book was released on 2011-08-02 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 can be made by raising the frontier of the traditional systems and increasing the efficiency of the modern systems. Among the production constraints studied were land preparation, soil fertility, weed control, pests and diseases, soil erosion, input access and moisture deficiency. The most significant constraints on the irrigated systems were input access and moisture deficiency.

Book excerpt: Master's Thesis from the year 2021 in the subject Environmental Sciences, Hawassa University (Institute of Technology), course: Irrigation, language: English, abstract: Small scale irrigation is one of the important pillars of the food security strategy of Ethiopian government that designed to promote the food production of small holder farmers. This study was aimed in assessment of the current status and causes of underperformance of the selected small scale irrigation schemes. To meet the objectives, the primary and secondary data were collected. The primary data were collected through household interviews, focus group discussions, key informant interviews, field observation and measurement. The secondary data were collected from office of water resource and irrigation, office of agricultural, and natural resource, and different published materials. Discharge measurement was done in the canal network to determine the water delivery performance indicators such as conveyance efficiency, relative water supply, and relative irrigation supply of the schemes. The selected physical, financial and agricultural indicators were also used to assess the performance and identify the current status of the schemes.

This book was released on 2020-07-21 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-scale irrigation (SSI) provides great benefits to farmers in terms of increased yields and profits, better food and nutrition security and greater resilience to climate shocks. Ethiopia has high potential for expanding SSI and has invested considerably in this area in recent years. Despite these investments, several challenges to further expansion of irrigation technologies remain. Different stakeholders in the country play important roles in overcoming these barriers to further scale technologies for SSI. This paper explores institutional arrangements for the diffusion of small-scale irrigation technologies by mapping the landscape of key actors involved, their interconnections, and their influence. This paper draws on an analysis of stakeholder data collected through two participatory workshops in Ethiopia, one at the national level and one at the Oromia regional level, using the Net-Map approach. Results show the dominance of government actors in the diffusion of SSI at both the national and regional levels, while most private sector and NGO actors remain in the periphery. Participants in both workshops highlighted the need for increased financing services to support the adoption of SSI and measures aimed at increasing the supply of high-quality irrigation equipment, such as modern water lifting technologies. One notable difference between the national and regional results was that at the regional level, farmers, and to some extent traders and input suppliers, were considered to be more influential in the diffusion of irrigation technologies, while they were considered marginal actors at the national level.

This book was released on 2009 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 covers about 5 and 9% of the total cultivated land area, respectively.

This book was released on 2021-12-21 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report focuses on Koga, in Ethiopia, and describes the process of developing, designing, piloting and evaluating potential solutions to increase water productivity sustainably, which is the third objective of component 4 of the project on WaPOR (Using Remote Sensing in support of solutions to reduce agricultural water productivity gaps). As irrigated areas expand, more attention must be paid to on-farm water management so as to allow for optimal use and distribution of water resources. Using WaPOR data, that is, remote-sensing based water productivity parameters, this report characterises the status of water use and productivity in the Koga irrigation scheme. It also uses the data to measure the changes occuring after the implementation of low-cost tools and irrigation practices so as to: increase yield and to reduce the water consumed or applied during the irrigation season.

Available in PDF, EPUB and Kindle. Book excerpt: Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management: Irrigation Case Studies examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book includes practical case studies from around the world, including locations such as Africa, Australia, China, India, the Middle East, the United States, and more. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change
