The Zambezi river is the fourth longest in Africa, crossing or bordering Zambia, Angola, Namibia, Botswana, Zimbabwe and Mozambique. The river basin is widely recognised as one of the most important basins in southern Africa and is the focus of contested development, including water for hydropower and for agriculture and the environment. This book provides a thorough review of water and sustainable development in the Zambezi, in order to identify critical issues and propose constructive ways forward. The book first reviews the availability and use of water resources in the basin, outlines the basin's economic potential and highlights key concerns related to climate vulnerability and risk. Focus is then devoted to hydropower and the water-energy-food (WEF) nexus, sustainable agricultural water management, and threats and opportunities related to provision of ecosystem services. The impact of urbanisation and water quality is also examined, as well as ways to enhance transboundary water cooperation. Last, the book assesses the level of water security in the basin, and provides suggestions for achieving Sustainable Development Goal (SDG) 6. Throughout, emphasis is placed on entry points for basin-level management to foster improved paths forward.

The central challenge encountered by Arizona and many other arid regions in the world is keeping a sustainable water supply in the face of rapid population growth and other competing demands. This book highlights new approaches that Arizona has pioneered for managing its water needs. The state has burgeoning urban areas, large agricultural regions, water-dependent habitats for endangered fish and wildlife, and a growing demand for water-based recreation. A multi-year drought and climate-related variability in water supply complicate the intense competition for water. Written by well-known Arizona water experts, the essays in this book address these issues from academic, professional, and policy perspectives that include economics, climatology, law, and engineering. Among the innovations explored in the book is Arizona's Groundwater Management Act. Arizona is not alone in its challenges. As one of the seven states in the Colorado River Basin that depend heavily on the river, Arizona must cooperate, and sometimes compete, with other state, tribal, and federal governments. One institution that furthers regional cooperation is the water bank, which encourages groundwater recharge of surplus surface water during wet years so that the water remains available during dry years. The Groundwater Management Act imposes conservation requirements and establishes planning and investment programs in renewable water supplies.

The essays in Arizona Water Policy are accessible to a broad policy-oriented and nonacademic readership. The book explores Arizona's water management and extracts lessons that are important for arid and semi-arid areas worldwide.

It is difficult to imagine anything more important to the human population than safe drinking water. Lack of clean drinking water is still the major cause of illness and death in young children in developing countries. In more fortunate communities, where water treatment is practiced, the primary aim of water authorities is to provide water that is free from pathogens and toxins. Most countries now have water quality regulations, or guidelines, which are driving water authorities to produce purer water, with the minimum of contamination from natural or man-made origin. At the same time, consumers are demanding that chemicals added during the treatment of drinking water be kept to a minimum. As a consequence, conventional clarification methods are being challenged to comply with the new regulations and restrictions and our understanding of the mechanisms involved is being tested as never before.
Interface Science in Drinking Water Treatment contains a rigorous review of water treatment practices from a fundamental viewpoint. The book includes material from leading experts in the field of water treatment, reviewing their specific fields of expertise against a background of colloid and surface chemistry, and examines each step of the journey from source to consumer tap. It therefore permits the reader to develop a deep understanding of the complex processes taking place and of the necessary treatments which are vital for the provision of safe and palatable drinking water. The book is aimed at researchers, educators and practitioners in science and engineering, particularly those involved in water treatment and colloidal chemistry.
- Covers all existing water treatment processes, approached from a fundamental surface and colloid science viewpoint
- Unique collection of R&D authors, all experts in water treatment processes
- Comprehensive review of water treatment with a complete list of references

Microbial granules have practical importance in anaerobic and aerobic biological wastewater treatment. Advantages of granules are retention of biomass in reactor, diversity of microorganisms, complex structure, and resistance to unfavorable conditions. Microbial granules can be used to treat municipal and industrial wastewater for removal of organic matter, xenobiotics, nutrients, and heavy metals.
The book covers almost all aspects of formation and use of microbial granules in wastewater treatment. The data on aerobic microbial granulation are related mostly to laboratory systems due to few pilot systems in the world using aerobic microbial granules. However, by the analogy with anaerobic granulation, which is now used worldwide, it is possible to predict wide applications of aerobic granulation. This book will help researchers and engineers develop these new biotechnologies of wastewater treatment based on aerobic granulation.

* Covers all aspects of formation, organization, and use of microbial granules in wastewater treatment
* Integrates engineering, microbiology, and biotechnology of microbial granules
* Comprises of deep fundamental data as well as practical information for applications of microbial granules in wastewater treatment

*** The follow-up to the highly influential UN-HABITAT publication Water and Sanitation in the World's Cities, described as "surely the most impressive and important publication to come out of the UN system for many years" by Peter Adamson, founder of New Internationalist *** The first major study of water and sanitation issues in the many thousands of settlements in which most of the people of the developing world live *** Essential reading for professionals, researchers, teachers and students Half of the world's people live in urban areas, and roughly a third of these live in desperate poverty without access to basic amenities. Taking on the themes of UN-HABITAT's Water and Sanitation in the World's Cities (2003), this new volume focuses on the deficiencies in the provision of water and sanitation where most of the populations of the developing world live: in towns and small cities. Drawing on extensive unpublished research and 15 commissioned papers from experts involved in designing and implementing innovative projects around the world, this is the first major study of the problems facing the smaller urban centers that are recognized to be of enormous importance by governments, international agencies, NGOs and service providers. Tackling these problems is a crucial part of development and of good governance, and critical to meeting the Millennium Development Goals. The volume will be essential reading for all professionals and researchers in the relevant fields and a valuable resource for teachers and students of urban development.

One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

The world's population is expected to reach the eight billion mark very soon. As a result, there is a need for increased industrial and agricultural production to ensure human wellbeing. This in turn generates huge amounts of waste. Current waste treatment solutions are effective, but usually require huge capital investment, are labour intensive and potentially lead to hazardous by-products. This book presents the latest non-biological approaches to address issues related to the abundance of waste, offering insights into best practices in various regions around the globe. It highlights techniques such as chemical extraction, pyrolysis and ultrasonics, and a number of chapters include individual case studies to further enhance readers' understanding. This comprehensive reference resource is intended for graduate students, researchers and scientists, and is also a valuable addition to all agriculture and biotechnology libraries.

Water policy seems in perpetual crisis. Increasingly, conflicts extend beyond the statutory authority, competence, geographical jurisdictions, and political constituencies of highly specialized governing authorities. While other books address specific policy approaches or the application of adaptive management strategies to specific problems, this is the first book to focus more broadly on adaptive governance, or the evolution of new institutions that attempt to resolve conflicts among competing authorities.

Adaptive Governance and Water Conflict investigates new types of water conflicts among users in the seemingly water-rich Eastern United States. Eight case studies of water quality, water quantity, and habitat preservation or restoration in Florida were chosen to span the range of conflicts crossing fragmented regulatory boundaries. Each begins with a history of the conflict and then focuses on the innovative institutional arrangements-some successful, some not-that evolved to grapple with the resulting challenges. In the chapters that follow, scholars and practitioners in urban planning, political science, engineering, law, policy, administration, and geology offer different theoretical and experience-based perspectives on the cases. Together, they discuss five challenges that new institutions must overcome to develop sustainable solutions for water users: Who is to be involved in the policy process? How are they to interact? How is science to be used? How are users and the public to be made aware? How can solutions be made efficient and equitable?

In its diverse perspectives and unique combination of theory, application, and analysis, Adaptive Governance and Water Conflictwill be a valuable book for water professionals, policy scientists, students, and scholars in natural resource planning and management.

Based on the author's more than 35 years of experience, Particles in Water: Properties and Processes examines particles and their behavior in water systems.

This book is divided into four parts. The first part, Preliminaries, begins by introducing the basic theme of the book. It provides an overview of the current status of water resources utilization, the likely scenario of future demands, and advantages and disadvantages of systems techniques. An understanding of how the hydrological data are measured and processed is important before undertaking any analysis. The discussion is extended to emerging techniques, such as Remote Sensing, GIS, Artificial Neural Networks, and Expert Systems. The statistical tools for data analysis including commonly used probability distributions, parameter estimation, regression and correlation, frequency analysis, and time-series analysis are discussed in a separate chapter.

Part 2 Decision Making, is a bouquet of techniques organized in 4 chapters. After discussing optimization and simulation, the techniques of economic analysis are covered. Recently, environmental and social aspects, and rehabilitation and resettlement of project-affected people have come to occupy a central stage in water resources management and any good book is incomplete unless these topics are adequately covered. The concept of rational decision making along with risk, reliability, and uncertainty aspects form subject matter of a chapter. With these analytical tools, the practitioner is well equipped to take a rational decision for water resources utilization.

Part 3 deals with Water Resources Planning and Development. This part discusses the concepts of planning, the planning process, integrated planning, public involvement, and reservoir sizing.

The last part focuses on Systems Operation and Management. After a resource is developed, it is essential to manage it in the best possible way. Many dams around the world are losing some storage capacity every year due to sedimentation and therefore, the assessment and management of reservoir sedimentation is described in details. No analysis of water resources systems is complete without consideration of water quality. A river basin is the natural unit in which water occurs. The final chapter discusses various issues related to holistic management of a river basin.
