Based on the suggestions made by the speakers of Plenary Session IV "Ch- lenges to the management of water resources and to countering deserti cation in the Mediterranean region" during the 15th Economic and Environmental Forum, the OCEEA proposed to organize a workshop on "Water Scarcity, Land Degra- tion and Deserti cation in the Mediterranean region - Environment and Security Aspects." In order to build on common synergies, OSCE sought co-operation with c- leagues from NATO, in particular from the Science for Peace and Security P- gramme. NATO has a longstanding expertise on the issue and had organised in Valencia, in December 2003, a NATO scienti c workshop on "Deserti cation and Security in the Mediterranean Region." The objective of the new proposed wo- shop would be to broaden its focus from the scienti c community to include also policy makers. 1 The workshop, aimed at government of cials from the Mediterranean Region, gathered representatives of Water management, Land degradation and Desert- cation Departments of Ministries of Environment and representatives from the Ministries of Foreign Affairs. In addition, policy makers, scientists and experts were also invited. The aim was to discuss how the OSCE, NATO and other c- petent organizations like the UNCCD, UNEP, MAP, and the EU could play a role in ensuring that environment and security linkages in terms of water scarcity, land degradation and deserti cation are addressed in the Mediterranean Region.

The Lake Governance book will focus on comparative analysis of governance structures by examining policy, legal and institutional structures of current transboundary commissions to develop a common framework for good governance of transboundary lakes. Cooperation among nations sharing natural resources is important for sustainable use of the shared resources. Lakes contribute a big part to GDP in most of the countries and in some cases are also responsible for providing fisheries (for food, source of protein and livelihood). Climate change and associated risks and uncertainties add more complexity to the problems. This book will explore current water governance challenges, knowledge gaps and recommend a framework for good lake governance.

This book describes the ecosystem of the Andean watersheds, covering the Californian valley, tropical Andes, and southern Andes. Case studies of the new methods and techniques used for hydrological research in the Andes are provided, and sustainability issues pertaining to Andean water resources are discussed in the context of climate change, social and economic issues, and public policy. Furthermore, the impact of economic development on the Andean ecosystem, specifically the effect on the water cycle and the water-energy-food nexus, are examined.

Focuses on the application of membrane technologies in removing toxic metals\metalloids from water. Particular attention is devoted to the removal of arsenic, uranium, and fluoride. These compounds are all existing in the earth's crust at levels between two and five thousands micrograms per kg (parts per million) on average and these compounds can be considered highly toxic to humans, who are exposed to them primarily from air, food and water. In order to comply with the new maximum contaminant level, numerous studies have been undertaken to improve established treatments or to develop novel treatment technologies for removing toxic metals from contaminated surface and groundwater. Among the technologies available, applicable for water treatment, membrane technology has been identified as a promising technology to remove such toxic metals from water. The book describes both pressure driven (traditional processes, such as Nanofiltration, Reverse Osmosis, Ultrafiltration,etc) and more advanced membrane processes (such as forward osmosis, membrane distillation, and membrane bio-reactors) employed in the application of interest. Key aspect of this book is to provide information on both the basics of membrane technologies and on the results depending on the type of technology employed.

In addition to presenting cutting-edge information and highlighting current trends and issues, the book proposes concrete solutions to help face this significant environmental threat. It is chiefly intended for researchers and industry decision-makers; international, national and local institutions; and NGOs, providing them with comprehensive information on the origin of the problem; its effects on marine environments, with a particular focus on the Mediterranean Sea and coasts; and recent and ongoing research activities and projects aimed at finding technical solutions to mitigate the phenomenon.

Water conflicts in India have now percolated to every level. They are aggravated by the relative paucity of frameworks, policies and mechanisms to govern the use of water resources. Based on the premise that understanding and documenting different types of water conflict cases in all their complexity would contribute to informed public debate and facilitate their resolution, Forum for Policy Dialogue on Water Conflicts in India, a collaborative initiative of the WWF project 'Dialogue on Water, Food and Environment', documented a number of such case studies. One of its kind in India, this book brings together an impressive sixty-three case studies - summarized status of the conflicts, the issues involved and their current position - and gives us a glimpse into 'the million revolts' that are brewing around water. While recognizing that each conflict is a microcosm of wider conflicts, the editors have classified these cases into eight broad themes that try to capture the dominant aspect of the conflict. These are: contending water uses; dams and displacement; equity-access-allocations; micro-level conflicts; water quality; trans-boundary conflicts; privatization; sand excavation and mining. With a mix of academics and activists as contributors, the book makes an important contribution to a new discourse on water in general, and water conflicts and conflict resolution in particular.

In Water Sheikhs and Dam Builders Francesca de Chatel discusses the problems and paradoxes of water resources in the Middle East and North Africa, exploring the past, present, and future of water in the region and exposing the roots of the current water crisis.

The author provides a colorful and diverse portrait of a resource that is inextricably entwined with the history and future of the region and its peoples. Based on four years of research and travel from Iran to Libya and from Israel to Syria, the book combines lively character sketches, interviews, travel descriptions, historical anecdotes, and hard facts to reveal the complexity of this invaluable resource. Besides identifying the causes of the current water crisis, the book also discusses the reasons behind the widespread lack of awareness of the problem among the general public. The book deals with a variety of themes, such as the role of water in religions and ideologies, the impact of large-scale water projects on people's perception of the resource, and the politics of water pricing. The first four chapters focus on the historical and cultural legacy of water in the region and form the background to the second part of the book, which addresses various aspects of the current crisis. The last two chapters look at the future of water management, identifying a number of strategies that could lead to a more sustainable water use.

By exploring the history and culture of water and approaching the subject from a human perspective, de Chatel takes an entirely new angle on the much-discussed question of water scarcity in the Middle East. Unlike other books on the subject that provide specialized geopolitical, economic, and hydrological analyses, Water Sheikhs and Dam Builders presents the reality of water scarcity through the eyes of those who have to confront the problem on a daily basis. As such, it will capture the interest of environmental scientists, water experts, and Middle East scholars as well as general readers with an interest in the Middle East and the environment.

Strategic Planning for Water examines the neglected relationship between planning for water and spatial planning. It provides the background to sustainable water management and assistance to spatial planners in understanding the complex water environment.

This extremely topical book examines the challenges of:

• how to ensure that water supplies are adequate to meet our future needs
• how to reduce the risk of flooding as we are faced by stormier winters and rises in sea levels
• how to better manage our waste water
• how to further improve the water quality of our rivers in response to the Water Framework Directive.

Essential reading for planners, developers and all those who must in future effectively incorporate water issues into their plans, developments and lifestyles if these are to be truly sustainable.

Since antiquity, humanity has used engineering techniques to manage the transport and distribution of its most important resource fresh water. Population growth and climate change are making the good management of water resources ever more essential and this book focuses on advanced methods for the control of water flow in open-channel systems.

Open-channel hydraulics are described by hyperbolic equations, derived from laws of conservation of mass and momentum, called Saint-Venant equations. In conjunction with hydraulic structure equations these are used to represent the dynamic behavior of water flowing in rivers, irrigation canals, transportation waterways and sewers. A lot of water is wasted because of poor management of such systems and automatic control has long been identified as a possible way to improve their operational management.

Building on a detailed analysis of open-channel flow modeling, Modeling and Control of Hydrosystems constructs control design methodologies based on a frequency domain approach. The difficulty involved with rigorous design of boundary controllers for hyperbolic systems is well known but, in practice, many open-channel systems are controlled with classical input output controllers that are usually poorly tuned. The approach of this book, fashioning pragmatic engineering solutions for the control of open channels is given rigorous mathematical justification. Once the control objectives are clarified, a generic control design method is proposed, first for a canal pool, and then for a whole canal. The methods developed in the book have been validated on several canals of various dimensions, from experimental laboratory canals to a large scale irrigation canal.

From the detailed analysis of realistic open-channel flow dynamics, and moving to the design of effective controllers, Modeling and Control of Hydrosystems will be of interest to control and civil engineers, and also to academics from both fields.

This volume describes various scenarios of conflict and cooperation over water resources among stakeholders in a variety of settings. It discusses treaty making over international rivers, bilateral cooperation on river development between South Africa and Lesotho, the political economy of water supply in the Pacific Island region, the establishment of the Mekong River Commission in Southeast Asia, comparative river basin management in the United States and South Korea, and the International Joint Commission formed by Canada and the United States to resolve boundary water conflicts. The book also explores national domestic conflicts over water resources in Bangladesh and China, Cold War hydropolitics in Southern Africa, water management conflicts in the Niger River Basin of West Africa, and water as commodity and source of conflict in Australia.

The central challenge for 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.

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.

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.

This book is an unique integrated treatise, on the concepts of fractional calculus as models with applications in hydrology, soil science and geomechanics. The models are primarily fractional partial differential equations (fPDEs), and in limited cases, fractional differential equations (fDEs). It develops and applies relevant fPDEs and fDEs mainly to water flow and solute transport in porous media and overland, and in some cases, to concurrent flow and energy transfer. It is an integrated resource with theory and applications for those interested in hydrology, hydraulics and fluid mechanics. The self-contained book summaries the fundamentals for porous media and essential mathematics with extensive references supporting the development of the model and applications.

Contamination of water supplies and the immediate availability of appropriate emergency responses to chemical, biological, radiological or nuclear (CBRN) events which result in contaminated water are becoming increasingly relevant and significant issues in the water industry and in the wider world. Consequently, new strategies and technologies are being constantly evolved and refined by leading experts in the field in order to achieve rapid and effective responses to water contamination events. Water Contamination Emergencies: Enhancing our Response brings together contributions from leading scientists and experts from both academia and industry in the field of water contamination and emergency planning. The book covers a wide range of topics including responses to water contamination emergencies, impacts on public health and commerce, risk assessment, analysis and monitoring, emergency planning, control and planning and threats to the water industry. This book is ideal for specialists in the field of water contamination and emergency response planning, especially researchers and professionals in industry and government who require an authoritative and highly specialised resource on water contamination management. The reader will gain an appreciation of the activities supporting the development of responses to contamination events; emergency actions required in response to the contamination of drinking water; and incident management. Also discussed are the importance of communication between organisations and the public; consumer perceptions and the need for robust and rapid screening of samples taken in response to potential contamination events in order to help answer the key question "Is this water safe to drink?"

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. The book offers clear and accessible methods for characterizing a range of particles both individually and as aggregates. The author delineates the principles for understanding particle properties and shows how such information contributes to the understanding and improvement of water treatment processes, including sedimentation, flocculation, and filtration. A distillation of the author's years of experience, the book explores practical applications of fundamental principles.

Outlining the origin, nature, and properties of particles in water, the author covers particle size, transport processes, and light scattering and provides a broad outline of important techniques for particle size determination. He discusses the important topic of surface charge, which plays a major role in colloid stability and interactions between particles, with some emphasis on the role of dissolved salts. The book gives an account of particle aggregation kinetics, the form of aggregates, and aggregate strength and explores coagulation and flocculation and the modes of action of some common additives used in these processes. The book concludes with an overview of important solid-liquid separation processes and the principles on which they are based.

The author presents the material in an easily accessible style, using just enough math to be clear but not so much as to be overwhelming. Highlighting the growing importance of advanced filtration systems in water treatment, this book provides an excellent summary of the behavior of particles in watersystems and in relation to the techniques designed to capture and remove them.

The problem of reservoir eutrophication and resulting increase of algal activity is common for seven Dutch waterworks. In this context, the text investigates dissolved air flotation (DAF) as an alternative for algae removal, compared to conventionally applied sedimentation.

This is the first monograph in English on the topic of the sienese acqueducts. The book reviews scholarly literature and archival sources including maps and diagrams, to better situate Siena's achievement in urban history and broadens our understanding of medieval technology and urban life. Michael P. Kucher argues that urban patronage of anonymous craftsmen provided the cultural foundations for the careers of better known engineers like Francesco di Giorgio and Leonardo da Vinci. The book joins the rapidly expanding field of works that focus on urban technology to shed new light on daily life in the medieval city.
