Inventory of water storage types in the Blue Nile and Volta River Basins by Johnston, Robyn M.,McCartney, Matthew Pdf

For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of integrated planning of storage in both basins. Recommendations are made for improved planning in the future.

The Volta River Basin by Timothy O. Williams,Marloes Mul,Charles A. Biney,Vladimir Smakhtin Pdf

The Volta River Basin (VRB) is an important transboundary basin in West Africa that covers approximately 410,000 square kilometres across six countries: Benin, Burkina Faso, Côte d’Ivoire, Ghana, Mali and Togo. Its natural resources sustain the livelihoods of its population and contribute to economic development. This book provides a comprehensive, interdisciplinary review and assessment of the issues and challenges faced. The authors provide a science-based assessment of current and future scenarios of water availability, the demands of key sectors, including agriculture and hydropower, and the environment under changing demographic, economic, social and climatic conditions. They also identify solutions and strategies that will allow available water resources to be sustainably used to improve agricultural productivity, food security and economic growth in the VRB. Overall, the work examines from a multidisciplinary and multi-stakeholder perspective the solutions and strategies to improve the use of water and other natural resources in the VRB to achieve enhanced food security, livelihoods and economic growth.

The Water Resource Implications of Changing Climate in the Volta River Basin by Matthew McCartney,Gerald Forkuor,Aditya Sood,Barnabas Amisigo,Fred Hattermann,Lal Muthuwatta Pdf

The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.

Agricultural Water Storage in an Era of Climate Change: Assessing Need and Effectiveness in Africa by Matthew McCartney,Lisa-Maria Rebelo,Stefanos Xenarios,Vladimir Smakhtin Pdf

By mitigating the vagaries of climate variability, agricultural water storage is widely anticipated to make a key contribution to climate change adaptation in Africa. However, if the planning of water storage is not improved, it is likely that many investments will fail to fully deliver intended benefits. This report describes the agricultural water storage continuum and some of the possible implications of climate change. A simple diagnostic tool which can be used to provide a rapid evaluation of the need and effectiveness of different water storage options, under existing and possible future climate conditions, is presented.

Shallow groundwater in the Atankwidi Catchment of the White Volta Basin: current status and future sustainability by Barry, Boubacar,Kortatsi, B.,Forkuor, G.,Gumma, M. K.,Namara, Regassa E.,Rebelo, Lisa-Maria,van den Berg, J.,Laube, W. Pdf

The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.

A case for pipelining water distribution in the Narmada Irrigation System in Gujarat, India by Shah, Tushaar,Krishnan, S.,Hemant, P.,Verma, S.,Chandra, A.,Sudhir, C. Pdf

Thanks to farmers’ resistance to provide land for constructing watercourses below the outlets, India’s famous Sardar Sarovar Project is stuck in an impasse. Against a potential to serve 1.8 million hectares, the Project was irrigating just 100,000 hectares five years after the dam and main canals were ready. Indications are that full project benefits will get delayed by years, even decades. In this paper, IWMI researchers advance ten reasons why the Project should abandon its original plan of constructing open channels and license private service providers to invest in pumps and buried pipeline networks to sell irrigation service to farmers.

Sustainable Use of Soils and Water by Fernando António Leal Pacheco Pdf

This book on the sustainable use of soils and water addressed a variety of issues related to the utopian desire for environmental sustainability and the deviations from this scene observed in the real world. Competing interests for land are frequently a factor in land degradation, especially where the adopted land uses do not conform with the land capability (the natural use of soil). The concerns of researchers about these matters are presented in the articles comprising this Special Issue book. Various approaches were used to assess the (im)balance between economic profit and environmental conservation in various regions, in addition to potential routes to bring landscapes back to a sustainable status being disclosed.

Managing Water and Agroecosystems for Food Security by Eline Boelee Pdf

Water protection, food production and ecosystem health are worldwide issues. Changes in the global water cycle are affecting human well-being in many places, while widespread land and ecosystem degradation, driven by poor agricultural practices, is seriously limiting food production. Understanding the links between ecosystems, water, and food production is important to the health of all three, and sustainably managing these connections is becoming increasingly necessary. This book shows how sustainable ecosystems, especially agroecosystems, are essential for water management and food production.

Environment and Society in Ethiopia by Girma Kebbede Pdf

Ethiopia is facing environmental and poverty challenges, and urgently needs effective management of its environmental resources. Much of the Ethiopian landscape has been significantly altered and reshaped by centuries of human activities, and three-quarters of the rural population is living on degraded land. Over the past two decades the country has seen rapid economic and population growth and unparalleled land use change. This book explores the challenges of sustaining the resource base while fuelling the economy and providing for a growing population that is greatly dependent on natural resources for income and livelihoods. Adopting a political ecology perspective, this book comprehensively examines human impacts on the environment in Ethiopia, defining the environment both in terms of the quantity and quality of renewable and non-renewable natural resources. With high levels of economic production and consumption also come unintended side effects: waste discharges, emissions of pollutants, and industrial effluents. These pollutants can degrade the quality of water, air, land, and forests as well as harm the health of people, animals, and other living organisms if untreated or disposed of improperly. This book demonstrates how the relationship between society and environment is inherently and delicately interwoven, providing an account of Ethiopia’s current environment and natural resource base and future considerations for environmentally sustainable development.

A Comparative Analysis of the Technical Efficiency of Rain-fed and Smallholder Irrigation in Ethiopia by Makombe, G.,Namara, R.,Hagos, F.,Awulachew, S. B.,Ayana, M.,Bossio, D. Pdf

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.

An Overview of the Development Challenges and Constraints of the Niger Basin and Possible Intervention Strategies by Regassa E. Namara,Boubacar Barry,Eric S. Owusu,Andrew Ogilvie Pdf

The Niger River Basin covers 7.5% of the African continent and is shared between nine riparian countries. The human population of the basin is growing at an average annual rate of about 3%, which makes the Niger River Basin one of the areas with the highest fertility rates in the world. The desert margin is expanding; climate change is negatively impacting rainfall; and urbanization, industrialization, and the human and livestock population are threatening the quantity and quality of available water resources. The basin population already suffers from chronic poverty. Based on a literature review, this paper suggests some key water-related and other interventions that are capable of easing the basin’s development challenges.
