Water Management in Africa and the Middle East: Challenges and Opportunities
This book provides a comprehensive description of groundwater resources in Ethiopia and its various dimensions (groundwater as resource, environmental functions, and socioeconomics). The prevailing knowledge of groundwater resources in Ethiopia (or elsewhere in Sub Saharan Africa) was based on geological and stratigraphic framework known nearly four decades ago (mainly 1960's and 70's). Thanks to the substantial geoscientific research since the 70's a new set of relevant geological/stratigrahpic data has been created that helps to re-define our understanding of groundwater resources in Africa as a whole and in Ethiopia in particular: a) For the first time the basement aquifer of Ethiopia has been described hydrogeologically based on genesis of regoliths (deep weathering and striping history); clear regional difference in groundwater potential is shown for the first time; comparative accounty has been given regarding groundwater occurrence in the generally low grade basement rocks of Ethiopia (Arabian Nubian shield) and high grade basement rocks of the rest of Africa. b) For the first time groundwater occurrence in multilayred sedimentary rocks account for spatial variation in degree of karstification; deformation history, and stratigraphy. c) The vast volcanic aquifers of Ethiopia which have previously classified based on their ages are now reclassified based on age, morphology (eg. groundwater in plateau volcanics, groundwater in shield volcanics) and aquifer structure. d) The loose alluvio lacustrine sediments which were known as least extensive in previous works based on areal cover are in fact shown to host the most voluminous groundwater resources in Ethiopia. These aquifers have now been described based on their geomorphology, extent, and genesis. The aim of this book is to use these newly created knowledge to redefine the understanding of groundwater resources in Ethiopia.
The first of three books in IFPRI's climate change in Africa series, West African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing 11 of the countries that make up West Africa -- Benin, Burkina Faso, Côte d'Ivoire, Ghana, Guinea, Liberia, Niger, Nigeria, Senegal, Sierra Leone, and Togo -- and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. West Africa's population is expected to grow at least through mid-century. The region will also see income growth. Both will put increased pressure on the natural resources needed to produce food, and climate change makes the challenges greater. West Africa is already experiencing rising temperatures, shifting precipitation patterns, and increasing extreme events. Without attention to adaptation, the poor will suffer. Through the use of hundreds of scenario maps, models, figures, and detailed analysis, the editors and contributors of West African Agriculture and Climate Change present plausible future scenarios that combine economic and biophysical characteristics to explore the possible consequences for agriculture, food security, and resources management to 2050. They also offer recommendations to national governments and regional economic agencies already dealing with the vulnerabilities of climate change and deviations in environment. Decisionmakers and researchers will find West African Agriculture and Climate Change a vital tool for shaping policy and studying the various and likely consequences of climate change.
This book contains 11 papers which cover a range of vital topics in the areas of water, agriculture, food security and ecosystems - the entire spectrum of developing and managing water in agriculture, from fully irrigated to fully rainfed lands. They are about people and society, why they decide to adopt certain practices and not others and, in particular, how water management can help poor people. They are about ecosystems - how agriculture affects ecosystems, the goods and services ecosystems provide for food security and how water can be managed to meet both food and environmental security objectives. This is the eighth book in the series.
For the past two decades, Integrated Water Resources Management (IWRM) has been the dominant paradigm in water resources. This book explores how ideas of IWRM are being translated and adapted in Mozambique, South Africa, Tanzania, Uganda and Zimbabwe. Grounded in social science theory and research, it highlights the importance of politics, history and culture in shaping water management practices and reform, and demonstrates how Africa has clearly been a laboratory for IWRM. While a new cadre of professionals made IWRM their mission, we show that poor women and men may not have always benefitted. In some cases IWRM has also offered a distraction from more critical issues such as water and land grabs, privatisation, the negative impacts of water permits, and a range of institutional ambiguities that prevent water allocations to small and poor water users. By critically examining the interpretations and challenges of IWRM, the book contributes to improving water policies and practices and making them more locally appropriate in Africa and beyond.
Today, raising capacity in water resources management entails supporting stakeholders and decision-makers to reach a common understanding on the priorities and necessary arrangements for sharing and allocating water-related goods and services. Valuation is central to this process, as setting priorities and making choices implies valuing certain uses and arrangements above others. Water valuation can help stakeholders to express the values that water-related goods and services represent to them. It also offers a means for conflict resolution and planning, informing stakeholders, supporting communication, and facilitating joint decision-making on priorities and specific actions. This report confronts concepts from the literature on water valuation with practical experiences from three local cases where an effort was made to embed existing valuation tools and methods in ongoing water resources management processes. It uses the lessons from this exploration to provide a first outline for a stakeholder-oriented water valuation process. This is expected to provide a useful starting point to help water professionals and policy-makers improve the use of water valuation as a means to support participatory processes of water resources management.
Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

Projects implementation in may Sub Saharan countries are always established to allieviate perceived need. In the case of water, the aim is to provide clean safe water to communities in needs. In most rural areas and in conflict prone areas, such kind of projects faces enormous challanges. South Sudan have been in war for decade and sectorian conflict affect many communities living in the rural areas. A number of factors affect the management of community water projects. Some of these risk factors are associated with conflict and continued political unrest in many sub saharan Africa. The most striking ones include competition among water service providers, use sub-standard equipment, political leaders interferences, limited finances, insufficient use of existing policies, incomplete project implementation and poor governance. The book is derived from a study carried in order to dentifiy, analyse and respond to risks arising either positively or negatively that affect the water projects rendering community at risk. A mixed research methods that involved both primary and secondary data sources was used to collect date for this book. A purposive sampling method used utilizing semi-structured questionnaires and interviews in order to collect releveance data and analyze the risks involved in the community water kiosks in South Sudan. Successsful community water project require holistic approach that should involves all the stakeholders, strengheneing institutional capacity and enactment of better laws and regulations including contract laws. In addition the use of modern business tools and techniques including cost management, operational management, risk management and project management can greatly enhance the performance of the water kiosk projects.
