Seminar paper from the year 2021 in the subject Agrarian Studies, grade: A, Haramaya University (Institute of Technology), course: Seiner Seminar, language: English, abstract: This text deals with the impact of irrigation water use on groundwater environment and soil salinity in Ethiopia. Irrigation systems have been under pressure to produce more with lower supplies of water. Various innovative practices can gain an economic advantage while also reducing environmental burdens such as water abstraction, energy use, pollutants, etc. Farmers can better use technological systems already installed, adopt extra technologies, enhance their skills in soil and water management, tailor cropping patterns to lower water demand and usage, reduce agrochemical inputs and more. Water scarcity has been defined as the point at which the aggregate impact of all users impinges on the supply or quality of water under prevailing institutional arrangements to the extent that the demand by all sectors, including the environment, cannot be satisfied fully.

Research Paper (undergraduate) from the year 2019 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, Haramaya University, course: Management of Arid and Salt Affected Soils, language: English, abstract: The aim of this study was to identify the nature and quantify selectively soil chemical properties of the study area, to characterize and categorize salinity soil based on their salt content of the study area and to give suggestion appropriated reclaim of salt affected agricultural land management practices. Soil salinity and alkalinity problems are commonly found in the arid and semi-arid regions of the earth due to insufficient annual rainfall to leach accumulated salts from the root zone. In other words, salt affected soils often occur in areas where soluble salts and sodium (Na) accumulate in soils through physical and chemical weathering of rocks or the pedogenic process of the soil development, atmospheric precipitation and fossil salts from marine or lacustrine environments. Moreover, heavy fertilizer application and use of poor-quality irrigation water and inadequate drainage have contributed to the development of salt affected soils and productivity deterioration of many soils in irrigated arid and semi-arid regions. Ethiopia is the first in Africa and the ninth country in the World having more than 11 million ha of salt affected soils which are mainly found in the Rift Valley, Wabi Shebele River Basin and various lowlands of the country. Following the establishment of large-scale irrigated farms, the problem become worse due to poor drainage system and inappropriate water management practices coupled with unsound reclamation procedures, To understand how improved soil fertility may assist in reaching these needs, it requires knowledge of salinity and sodicity related soil chemical properties the soils of the land’s agriculture. Such knowledge is believed to help the producers and production managers to understand about and make the necessary modifications in the soil-salt-water balance.

Sub-Saharan Africa, the poorest region worldwide, has only recently begun to fully address the issues of meeting the water needs of its rapidly growing population, to reduce the deepening poverty besetting the region and to accelerate economic growth. The Nile Basin, characterized by sharp spatial and temporal variations in water resources and including countries with different economies, social and political structures and capacities, illustrates the challenges of developing and managing the waters of the Nile River and its tributaries, lakes and wetlands equitably among its 10 riparian countries. Ethiopia, the major source of the Nile but one of the poorest countries in the Nile Basin, has recently begun to implement plans to harness more Nile water through hydroelectric and irrigation development both for national use and for transboundary development as part of the Nile Basin Initiative. The Ethiopian government and communities, by using different management approaches and resources, are trying to boost water, energy and food production, strengthen conservation efforts and mitigate potential repercussions of water resources development. These initiatives and programs have not been comprehensively examined. In this study, the editors address these and other issues surrounding water resources management in all economic and water sectors in Ethiopia within the setting of the Nile Basin, the first comprehensive treatment of this subject. The wide scope of this book is consistent with the tenets of integrated water resources management, which demand that all water uses be managed in an integrated fashion for optimum and sustainable benefits to all water users, both humans and ecosystems. This book reveals the impacts of various resource management approaches and practices in Ethiopia and the Nile Basin. Specifically, it examines how deforestation and prevailing land use practices have exacerbated soil aridity and flood events, why irrigated agriculture and hydropower development have caused floodplain degradation, livelihood hardships and water-related diseases, where industrial and agricultural development is increasingly polluting water resources, how household water supplies can be obtained through rainwater harvesting and the dependence on hydropower reduced through alternative energy sources and how misguided government policies have impeded efforts to deal with these and other challenges. Results reveal dynamic interrelationships between these processes and identify the human and environmental driving forces, which must be understood in effective integrated water resources management. Another unique contribution of this book is the examination of the role of government and communities in managing water resources in Ethiopia. Results show that the top-down approach used by the socialist Derg government in soil and water conservation and social programs exacerbated water problems and reduced community participation. Moreover, the failure of its economic program reduced agricultural production, increasing dependency on relief food and further impeding community initiatives in soil and water conservation activities. Many elements of central planning persist in spite of the decentralization drive by the current government, but there is evidence that integration of the top-down and bottom-up approaches to water resources management is necessary (and feasible) to strengthen and up-scale programs to the national level. The book identifies a number of customary water and soil management practices and institutions that may strengthen especially community-based rainwater harvesting, small-scale irrigation, reforestation, soil and water conservation and flood control efforts. This is an important book for researchers and students of resources management, rural development, hydrology and African studies.
