Impacts of improving water management of smallholder agriculture in the Upper Blue Nile Basin

With its total area of about 200,000 square kilometers (km2), which is 20% of the country’s land mass, and accommodating 25% of the population, the Upper Blue Nile Basin (Abbay) is one of the most important river basins in Ethiopia. About 40% of agricultural products and 45% of the surface water of the country are contributed by this basin. However, the characteristic-intensive biophysical variation, rapid population growth, land degradation, climatic fluctuation and resultant low agricultural productivity and poverty are posing daunting challenges to sustainability of agricultural production systems in the basin. This calls for technological interventions that not only enhance productivity and livelihoods in the basin, but also bring about positive spillover effects on downstream water users. In this study, the farming systems in the basin have been stratified and characterized; and promising agricultural water management technologies, which may upgrade the productivity of smallholder rainfed agriculture while improving downstream water quality, have been identified. As a consequence, supplementary and full irrigation using rainwater and drainage of waterlogged soils are recognized as being among the promising agricultural water management technologies that can be easily scaled-up in the basin. The magnitude of the impacts of these technologies on the productivity of the upstream farming systems and the concomitant effects on the downstream water flow and quality are under investigation, assuming an assortment of scenarios.Length: pp.7-21River basinsFarming systemsCerealsRainfed farmingWater harvestingIrrigated farming

Improved water and land management in the Ethiopian highlands and its impact on downstream stakeholders dependent on the Blue Nile

Improved water and land management in the Ethiopian highlands and its impact on downstream stakeholders dependent on the Blue Nile – short title Upstream-Downstream in Blue Nile River project is one of the projects in the Nile Basin supported by the CPWF. It was implemented during from 2007 to 2009 through a partnership of 8 institutions. The Blue Nile is the major tributary of the Nile River, contributing about 62% of the Nile flow at Aswan. About two thirds of the area of this densely populated basin is in the highlands and hence receives fairly high levels of annual rainfall of 800 to 2,200 mm. However, the rainfall is erratic in terms of both spatial and temporal distribution with prolonged dry spells and drought often leading to crop failures. Currently, water resources are only marginally exploited in the upper basin but are much more developed in the downstream reaches. The population, located in the downstream part of the Blue Nile, is dependent on the river water for supplementary irrigation and energy production. Canal and reservoir siltation is a major problem, adding the burdens of poor riparian farmers. This project was envisaged to improve the scientific understanding of the land and water resources of the basin, and hypothesized that with increased scientific knowledge of the hydrological, watershed, and institutional processes of the Blue Nile in Ethiopia (Abbay), constraints to up-scaling adaptable best practices and promising technologies (technical, socio-economic, institutional) could be overcome, which will result in significant positive impacts for both upstream and downstream communities and state

Statues quo analysis, characterization and assessment of performance of irrigation in Ethiopia

Impact of irrigation on poverty and environment in Ethiopia: draft proceedings of the symposium and exhibition, Addis Ababa, Ethiopia, 27-29 November 2007. Colombo, Sri Lanka: International Water Management Institute (IWMI).This paper first looks in to the background on major challenges of Ethiopia with respect to poverty. It discuses the root cause of poverty and its vicious cycle nature, the interlink of population growth, the scarcity of land and natural resources, the extension of agriculture in to marginal land, the decreasing productivity, inability to invest and deepening of poverty and further aggravation as a result of various shocks such as drought, flood, war, etc. The paper also looks in to the importance of the broad agricultural water management in general and irrigation in particular with respect to increasing productivity and capability to break the vicious cycle and opportunity to reverse in to virtuous cycle that can help eradicate poverty and develop the poor economy. The paper also looks in to how poor management of water resources and impacts of variability of rainfall and related drought affecting the socio-economy and the overall wellbeing of the country to the extent that significant population became dependent on imported food. Results of broad assessment of water resources, database of irrigation development and potential, characterization by typology and major performance in Ethiopia are presented. Key water resources information related to each of the 12 river basins in Ethiopia is summarized. Details of existing irrigation and future potential are also captured in the paper. A geographic information system (GIS) database describing irrigation by typology, region and location, scheme size, type of structures, water source, number of beneficiaries, investment cost, etc, are some of the important attributes of the database. In addition, schemes that are operational and failed are identified in the database. Based on the broad database, performances of the schemes are highlighted. Furthermore, the various sites that are used in the detail study and the selection criteria for the impact of irrigation on poverty and environment project and the specific characteristics of these sites are described

Economics of selected water control technologies and their successful use: the case of Ethiopia

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. Marginal value products of farm inputs are found to be positive but their magnitudes differ by type of control structures, crop type, agro-ecology and regions. The net present values of all water control structures are positive. There is a favorable precondition for sustainable adoption of these controls technologies and institutionalizing some sort of cost recovery schemes. The level of education, the ratio of irrigated land allocated to irrigated annuals and perennials, access to markets and off-farm income are found to have significant effect on successful use of these control structures. Recommendations and policy implications are drawn accordingly
