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 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.

In Africa, most major rivers, freshwater lakes, and aquifers are shared by two or more countries. These nations are becoming increasingly vulnerable to conflict, and their vulnerabilities are made more acute by climatic variations in precipitation, increasing urbanization, industrialization and environmental degradation. The concept of resilience and vulnerability as it relates to water resources is tackled in this report within the framework of sustainability and relates to the ability of the human and bio-physical systems to adapt to change.--Publisher's description.

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.

Fresh water is one of man's most vital needs. The distribution of water within river basins has a direct bearing on the organization of water resources development to meet this ever-expanding need. River basins, despite their very great diversity in other respects, have one physical characteristic in common: each is a more or less self-contained unit within whose bounds all the surface and part or all of the ground waters form an interconnected, interdependent system. This inter dependence has such far-reaching implications - for pollution and flood control, apportionment of supply, relations between upstream and downstream riparians, to mention only a few examples - that the river basin has become almost universally accepted (within the past 20 or 30 years at least) as the unit of optimal water resources de velopment. Professor Teclaff's work (which was originally submitted to the New York University School of Law as a doctoral dissertation) is the first fully developed response to the important resolution passed by the International Law Association at its New York meeting in I958 recognizing the legal nature of the international river basin. His study quite properly, therefore, poses the question whether the adoption of the river basin unit is a temporary phenomenon, reflecting the current stage of technology and of administrative, economic, and legal thought on water resources development, or whether the de terminative influence of the river basin's physical unity which has always operated in the past will continue to operate in the future.

Freshwater is needed in every aspect of life and is probably the most fundamental resource in sustaining life. It has been and will remain a key determinant of population growth and distribution, social and political organization and the quality of life. The aim of this study is to evaluate the costs and benefits as well as the tradeoffs and complementarities across water using sectors in the Volta River basin, notably Burkina Faso and Ghana. The model used was coded in the modeling language of the General Algebraic Modeling System. The author points out that profits per unit of water and hectare vary by crop and that liberalizing crop patterns could increase farmer profits from crop production. The study shows that increasing irrigated areas through inefficient water use systems in the basin will effectively render un-operational, the small hydropower projects in Burkina Faso and reduce the amount of power that the Akosombo reservoir can generate per month.

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 guide to help planners and engineers to the improvment of future water projects. The past century of global experience on water projects is presented as the basis for creating new approaches. First-hand analyses, including 35 case studies from 25 countries, portray the influence of politicians, biologists, engineers, computer models and physicians on the spectacular successes and failures of the builders of canals and dams. By drawing on this experience, the author outlines methods for assessing, predicting and preventing major water-associated diseases around large dams, canals and irrigation systems.

Water Resource Conflicts and International Security: A Global Perspective is an edited collection by Dhirendra K. Vajpeyi which analyzes the increasing global demand for water in economic and social development, and the dire need to efficiently manage this vital natural resource, particularly in water-scarce countries in the Middle East, Asia, and Africa. Several environmental- and human-induced factors, such as urbanization, industrialization, climate change, and agricultural needs, have created a near-crisis situation in many countries. Subsequently, there is an increasingly intense competition to utilize available water resources in these most heavily-affected regions; transboundary rivers, lakes, and streams which are shared by more than one country pose potential for political conflict, armed conflict, and, in the best of cases, cooperation. The contributors of Water Resource Conflicts and International Security present ten case studies in seven chapters, highlighting the competition between countries in Asia, Africa, and the Middle East. In his conclusion, Dhirendra K. Vajpeyi suggests several policy measures that governments may implement in order to minimize the potential for conflict.

Household water provides the entry point for this ethnography and study of institutional change. The book discusses the political economy of poverty and presents the polyphone discourse on water and the environment. It outlines water history and water rights from the 1970s onwards, and analyzes social dynamics. It offers a critical voice in the debate on climate change by arguing that local and global perceptions are not necessarily coherent.
