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.

An “hydro-political” assessment of water governance in the Volta Basin is one of two preparatory activities intended to guide and inform the development of a generic methodological model for building local indigenous institutional principles into international/transboundary river basin institutional arrangements. This report details from a “top-down” perspective, the historical developments of water governance of the Volta River Basin, paying special attention to the economic, political and social dynamics of water management within the legal and institutional frameworks in the Ghana and Burkina Faso portions of the Volta basin. The findings are based primarily on literature review, interviews with some key professionals and to some extent, previous knowledge and field experience

With "integrated water resources management" (IWRM) the current buzzword in international circles, the real question is: how to operationalise a truly multidisciplinary approach to the effective management of shared watercourses. Based largely on the actual experience of HELP (Hydrology for the Environment, Life and Policy), the overall aim of the book is to produce a series of case studies from around the world (from the Aral Sea to Zimbabwe) that demonstrate how the "gaps" between hydrology, water law and management are actually bridged in practice. Is hydrological data relevant and used in the formulation of national and international water law and policy? Cases cited include examples of where this has happened and been successful or unsuccessful and where this has not happened and led to problems. This will act as a guide to how future water laws and polices can be made more effective via the use of accurate and up to date hydrological information.

This book presents papers from an international conference, held in Bonn, Germany in February 2005, that dealt with integrated water resources management in industrialized and developing countries. The papers detail such emerging concepts as blue and green water, virtual water, the water footprints of nations, multi-agent modeling, linkages between water and biodiversity, and social learning and adaptive management.

The book includes seventeen excellent researched and documented papers that reflect the diversity of thought, ideas and experiences related to IWRM. They draw from an extensive, inclusive and geographically representative range of theoretical propositions and practical examples. These include the implementation status of the IWRM concept at local, basin, regional and national levels; its appropriateness for the twenty-first century; main implementation gaps from the institutional, legal, policy, governance, management and technical viewpoints; the likelihood that IWRM’s entrenchment in laws, regulations and policies has led to smoother implementation and the reasons why that has been the case; reflexions on whether the attention given to IWRM is pushing other alternatives to the policy periphery; and the new conceptual constructions that can be put forward for discussion in the international arena. For the development and water communities it is imperative to debate and reach towards more illustrative conclusions regarding whether the promotion of the IWRM concept and its actual implementation status have been beneficial for development and how the notion could evolve to achieve this end. In-depth objective and constructive discussions, arguments, proposals and ideas are put forward for analysis by all interested parties. The book has the objective of fostering scholarly exchange, encouraging intellectual debate and promoting the advancement of knowledge and understanding of IWRM as a concept, as a goal per se and as a strategy towards development goals. This book was published as a special issue of the International Journal of Water Resources Development.

This report summarizes the findings of a collaborative effort to map and assess irrigated areas in the Limpopo Province, South Africa. The study was conducted by the International Water Management Institute (IWMI) in collaboration with the Department of Agriculture, Forestry and Fisheries (DAFF) and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the DAFF-supported ‘Revitalization of irrigation in South Africa’ project. Based on a combination of Landsat and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data, previous irrigated area mapping exercises carried out by DAFF and three-field ground truthing (GT) surveys, a total of 1.6 million hectares (Mha) of cropland were identified, with 262,000 ha actually irrigated in the 2015 winter season. The study also found that only 29% of all land equipped with center pivots was actually irrigated.
