The United Nations World Water Development Report, published every three years, is a comprehensive review providing an authoritative picture of the state of the world's freshwater resources. It offers best practices as well as in-depth theoretical analyses to help stimulate ideas and actions for better stewardship in the water sector. It is the only report of its kind, resulting from the collaboration and contributions of the 26 UN agencies, commissions, program, funds, secretariats and conventions that have a significant role in addressing global water concerns. The news media are full of talk of crises - in climate change, energy and food and troubled financial markets. These crises are linked to each other and to water resources management. Unresolved, they may lead to increasing political insecurity and conflict. Water is required to meet our fundamental needs and rising living standards and to sustain our planet s fragile ecosystems. Pressures on the resource come from a growing and mobile population, social and cultural change, economic development and technological change. Adding complexity and risk is climate change, with impacts on the resource as well as on the sources of pressure on water. The challenges, though substantial, are not insurmountable. The Report shows how some countries have responded. Progress in providing drinking water is heartening, with the Millennium Development Goal target on track in most regions. But other areas remain unaddressed, and after decades of inaction, the problems in water systems are enormous and will worsen if left unattended. Leaders in the water sector can inform decisions outside their domain and manage water resources to achieve agreed socioeconomic objectives and environmental integrity. Leaders in government, the private sector and civil society determine these objectives and allocate human and financial resources to meet them. Recognizing this responsibility, they must act now Two volume set: 336 + 96 pages (case studies). Includes CD-ROM. Published jointly with UNESCO Publishing.

Why do many water management projects, begun with the best of intentions, still fail? How is it that large infrastructural water works often encounter opposition? Is it perhaps, among other things, the lack of attention for the cultural context? These and other intriguing questions are dealt with in this book. The authors, having 20 years of experience on water and sanitation in an international context, have investigated the relationship between water and culture world-wide in order to find new keys to successful and sustainable water management.

This book is based on extensive research and is intended to form a cultural road towards new sustainable water management practices. "Water: a way of life" takes the reader on a water journey through time and across the world's continents. Along the way it explains the past and present ways in which different cultures around the world, both traditional and modern, view and manage water in response to the distinct environment they inhabit. As beliefs and values are at the heart of any culture, it also highlights the views of the main world religions on water and its use. A better understanding of cultural water beliefs and practices may lead to new concepts for future sustainable water management - from flood management to water supply, sanitation and irrigation management.

The book will be useful to water professionals exporting knowledge and technologies to foreign countries where the challenge is to create sustainable solutions for water management by taking into account local, cultural factors. It is also intended to encourage world leaders, politicians and decision-makers responsible for water management to use their power, knowledge and influence to really make a change for the benefit of the people they represent. In this way, water can become a source of cooperation rather than a source of conflict.

The authors trust that this book, about water and culture, intended for a truly international audience, will be a source of inspiration.

Traditional approaches to hydrology have favoured a reductionist perspective. This text argues that hydrologists of the 21st century must increasingly look beyond the traditional boundaries of river channel or river catchment areas to consider new questions: firstly, how water resources should be managed in an integrated and sustainable way with a growing appreciation of the global dimension to water resource problems; secondly, how the search for solutions to water pollution, flooding, drought and environmental degradation requires a broader understanding of transboundary connections between components of the hydrosphere across a range of spatial and temporal scales. In an emerging age of water shortage, increasing dependence will also be placed upon existing monitoring and water distribution networks. Advances in data gathering systems and hydrological modelling have created new opportunities for assessing and managing these water resources. Similarly ecohydrology and palaeohydrological techniques are generating new types of data for model development and testing. This text will provide an excellent overview for post-graduates and researchers studying hydrology, meterology, environmental science and related topics. It will also be useful as supplementary reading for 2nd/3rd year undergraduates in these areas. The ruins of the flooded Derwent village emerged from Ladybower Reservoir, Derbyshire UK in autumn 1995. This image highlights a number of issues pertinent to contemporary hydrology such as: winter droughts severely restrict the replenishment on upland communities; the uneasy relationship between forestry and water resources in water supply catchments; water quality problemsassociated with acidification, turbidity and sedimentation; the aesthetic and ammenity value of impounded waters

An increment of urban flood risk in many areas around the globe is expected, accentuated due to climate change and urbanisation. Thus, appropriate flood risk management is crucial. Conventional approaches focus on grey infrastructure, which frequently do not address the root causes of risk. A change of paradigm is needed to develop effective adaptation strategies. Green-blue infrastructure (GBI) is a central concept to achieve adaptation to climate change. Its main strength is the ability to deliver multiple benefits. Although strong evidence exists demonstrating that GBI is a sustainable solution to reduce flooding, its adoption is still slow. Therefore, the objective of this research is to help decision-makers to adopt adaptation strategies to cope with flood risk while achieving other benefits. This study provides a framework which introduces co-benefits into decision-making for stormwater infrastructure planning. Besides, the multiple benefits are quantified and their impact on helping GBI implementation are evaluated. Finally, the effects of including co-benefits on the selection of flood mitigation strategies and the trade-offs among cost and benefits are assessed. This work contributes to enhance planning processes for flood mitigation combining green-blue-grey measures. It provides tools and knowledge to facilitate holistic decision-making, in order to ensure safe and liveable urban spaces for current and future conditions.

This volume provides an analytical and facts-based overview on the progress achieved in water security in Latin America and the Caribbean (LAC) region over during the last decade, and its links to regional development, food security and human well-being. Although the book takes a regional approach, covering a vast of data pertaining to most of the LAC region, some chapters focus on seven countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico and Peru). A full understanding of LAC's trends progress requires framing this region in the global context: an ever more globalized world where LAC has an increasing geopolitical power and a growing presence in international food markets. The book's specific objectives are: (1) exploring the improvements and links between water and food security in LAC countries; (2) assessing the role of the socio-economic 'megatrends' in LAC, identifying feedback processes between the region's observed pattern of changes regarding key biophysical, economic and social variables linked to water and food security; and (3) reviewing the critical changes that are taking place in the institutional and governance water spheres, including the role of civil society, which may represent a promising means to advancing towards the goal of improving water security in LAC. The resulting picture shows a region where recent socioeconomic development has led to important advances in the domains of food and water security. Economic growth in LAC and its increasingly important role in international trade are intense in terms of use of natural resources such as land, water and energy. This poses new and important challenges for sustainable development. The reinforcement of national and global governance schemes and their alignment on the improvement of human well-being is and will remain an inescapable prerequisite to the achievement of long-lasting security. Supporting this bold idea with facts and science-based conclusions is the ultimate goal of the book.

It also reflects the latest advancements in treatment technologies and reviews new laws and regulations related to drinking water.

This book reports the first systematic monitoring and modelling study on water availability, water quality and seawater intrusion of the Shatt al-Arab River (SAR) on the border of Iraq and Iran, where causes and concentration levels of salinity have not yet been fully understood, let alone addressed, leading to conflicting perceptions of its origin (external or internal), the natural conditions and the practices that can explain the current critical conditions. Current scientific knowledge on the SAR salinity problem is deficient, partially due to the complex and dynamic interaction between marine and terrestrial salinity sources, including return flows by water users of the different water sectors in the Euphrates and Tigris rivers upstream of the SAR. The development of a new series of monitoring stations and various modelling approaches helped to better understand the interactions between these different sources. The comprehensive and detailed dataset formed the basis for a validated analytical model that can predict the extent of seawater relative to other salinity sources in an estuary, and for a hydrodynamic model that can predict salinity changes. The adaptability of the models to changing conditions makes them directly applicable by water managers. The procedure can be applied to other comparable systems.

This title includes a number of Open Access chapters. The quantity and quality of waste generated and discharged into natural water bodies is a topic of serious concern. Consequently, there is a need for different strategies to address wastewater treatment and subsequent reuse, especially in arid and semi-arid areas where water shortages are the rule. Biological treatment processes constitute crucial tools in the biodegradation of organic matter, transformation of toxic compounds into harmless products, and nutrient removal in wastewater microbiology. Edited by a professor of genetics and microbiology with extensive research, this compendium provides an overview of the most current research into many facets of wastewater bioremediation. The book is broken into three sections: microbial communities for wastewater treatment, environmental factors, and treatments. It provides discussions on biological treatment processes for different types of wastewater, such as municipal wastewater and wastewater from tanneries; how environmental factors such as season dynamics affect the diversity of bacteria; and applications and treatment. The range of topics presented will be valuable for biological engineers and others involved with wastewater management. Researchers will find a wealth of studies that will prove fruitful for future investigation.

The rate of global increase in water abstraction for irrigation has been declining since the 1970's due to declining potentials for large and medium-scale irrigation developments, and is expected to further decline in the next decades. As such the significant proportion of the expected increase in production would have to be supplied from existing irrigated and /or cultivated lands. This in turn could be achieved by enhancing land and water productivity through improved performance and optimal operation and maintenance. With less than 15% of over 5 million ha irrigation potential harnessed, irrigation devolvement in Ethiopia remained low. Over 70% of the developed irrigation in the country belongs to small-scale irrigation serving smallholder farmers. While accelerated development of new irrigation, particularly of large and medium-scale schemes is relevant in Ethiopia, ensuring the performance and sustainability of existing schemes is also equally important. The existing irrigation schemes in Ethiopia are generally characterized by an overall performance and technical sustainability levels of below expectation. This thesis evaluates the performance of two large-scale (Wonji-Shoa and Metahara) and two community-managed (Golgota and Wedecha) irrigation schemes located in the Awash River Basin of Ethiopia. The study focussed on hydraulic/water delivery performance in the large-scale schemes, and on comparative and internal irrigation service (utility) evaluation in the community-managed schemes. Water delivery performance was evaluated using routine data and hydrodynamic modelling. Farmers' utility was evaluated using qualitative responses of water users. Major performance challenges in each category of schemes were addressed and operational/water management options for improvement were identified.

Droughts occur in arid and semi-arid areas of the world, but also in humid areas, and can develop over short periods (flash drought) or longer periods (seasons/decades). Even though progress has been made, it remains difficult to adequately characterize, monitor, forecast and manage droughts, due to their multi-faceted nature. Usually, drought does not directly cause fatalities, but a wide range of socio-economic and environmental effects may occur, and, depending on the region, water-and food-related diseases and casualties can be triggered. Europe has regularly been hit hard by drought (e.g. recently Russia), and large portions of USA, Mexico, Brazil, China, India, Central Asia, South Africa, the Great Horn of Africa, or Australia, have been affected by drought. So globally, drought affects more regions, and more people, than other natural hazards. Additionally, climate change projections for many areas indicate that droughts are likely to become more frequent and more severe due to the increased variability of precipitation and temperature, tied in some cases to decreased average precipitation and increased average temperature. Hence, there is an urgent need to improve drought preparedness through measures that reduce vulnerability to drought and the risks they pose, in particular considering the uncertain future. Drought. Research and Science Policy Interfacing includes contributions to the International Conference on DROUGHT: Research and Science-Policy Interfacing (Valencia, Spain, 10-13 March 2015), the final event of the EU FP7 research project DROUGHT-R&SPI (Fostering European Drought Research and Science-Policy Interfacing). The book aims to foster development of drought policies and plans to reduce risk and vulnerability, and to enhance preparedness and resilience. The book addresses the following topics : (1) past, present and future of droughts (natural hazards, identification and characterization, impacts); (2) indicators, monitoring and forecasting (including early warning systems), risk and vulnerability assessment and reduction at different scales, and (3) preparedness and mitigation options (risk and vulnerability perception, water management and governance under drought conditions, design and implementation of drought policies and plans from the local to the regional, national and international levels, research Interfaces with drought policies). Drought. Research and Science Policy Interfacing will be of interest to researchers and professionals in those fields related to drought, such as climatology, meteorology, hydrology, agronomy, ecology, water economy, and water management, as well as to policy makers involved in drought preparedness and mitigation strategies at local, regional, national and international levels.

The discussion on arsenic in the environment is complex and must grasp the importance of very many, mostly unrelated works on individual aspects. This volume represents one of the first comprehensive and interdisciplinary examinations into arsenic's behaviour in air, water, soils, sediments, plants and the human body. Based on state-of-the-art investigations into the global arsenic cycle, the related human toxicology and available remediation technologies, arsenic is assessed holistically in all the environmental compartments. Using the results of primary research, the authors offer concrete suggestions for risk reduction and management of environmental pollution that allow the reader to successfully tackle similar problems and find sustainable solutions. The book consists of three essential parts: Review of the current knowledge of arsenic behaviour in the environment (global biogeochemical cycles), toxicology, remediation techniques, immobilization technologies and environmental legislation Case studies for mining-related arsenic problems Discussion of mitigation and remediation technologies and approaches such as environmental education, hygiene training, backed by real experience and successful implementation in the study area In a highly coherent manner, the book makes use of 120 tables and figures, a large number of literature citations, and very detailed subject index (that encompasses references) to provide rapid and up-to-date access to all relevant information. Cross-references provide a great manoeuvrability between the chapters. The book delivers very insightful and hands-on approaches for graduate students and professionals working on arsenic questions not only in environmental science, but also in the fields of environmental engineering, medicine and social science.

This book focuses on industrial wastes that either join the streams or other natural water bodies directly, or are emptied into the municipal sewers, and their characteristics vary widely depending on the source of production and the raw material used by the industry, even during pre-industrial, industrial period and prospect of wastewater treatment for water resource conservation. The treatment of industrial wastewater can be done in part or as a whole either by the biological or chemical processes. Advanced treatment methods like membrane separation, ultra-filtration techniques and adsorption are elaborated. It would emphasize and facilitate a greater understanding of all existing available research, i.e., theoretical, methodological, well-established and validated empirical work, associated with the environment and climate change aspects.

Water and wastewater treatment normally take place in a series of continuous flow units, each designed to perform a step of the intended purification process - typically involving coagulation or flocculation, sedimentation or filtration, and disinfection. The flow pattern governs the residence/contact time, turbulence levels, collisions and shear to which different fluid portions are subjected in their passage through the unit. The efficiency of a given unit depends as much on the relevant physical, chemical or biological reaction as on the flow pattern taking place inside. This combined effect of flow features on process efficiency is often overlooked in teaching the design of water and wastewater treatment units, and so it is not uncommon to find treatment units in operating in a cost-ineffective way, causing health and environmental problems. This book introduces engineering students to concepts and practical measures associated with the rational design of treatment units, leading to more realistic and potentially optimal solutions for new units as well as for retrofitting existing units. Key basic concepts and suitable analytical tools are described, illustrated and worked through using practical examples. Engineering undergraduates and graduates should benefit from the book while undertaking standalone modules on the topic and/or supplementary classes of existing courses on unit treatment processes. The book may also be useful for technical and engineering staff involved in designing and/or retrofitting units for better cost-effectiveness and footprint reduction of the water and wastewater treatment sector.

The issue of water quality monitoring is becoming a huge area as the EU requirements for cleaner water increase. On-line monitoring involves measuring a body of water constantly and in-situ as opposed to analysing samples in the lab. Currently filling the gap in the market, "Wastewater Quality Monitoring: On-line Methods" provides information on how to produce the best analyses of wastewater in order to meet the above mentioned requirements.

This reference will prove invaluable to all local water companies, industrial companies producing wastewater, as well as environment agencies and researchers.

One of the most challenging aspects of climate change has been the increased pressure on water resources limited by droughts and new rain patterns, which has been exacerbated by rapid modernization. Due to these realities, disputes across national borders over use and access to water have now become more commonplace. This study analyzes the history and adjudication of transboundary water disputes in five international courts and tribunals, two US Supreme Court cases, and boundary water disputes between the United States and Canada and the United States and Mexico. Explaining the circumstances and outcomes of these cases, Kornfeld asks how effective the courts and tribunals have been in adjudicating them. What kind of remedies have they fashioned and how have they dealt with polycentric and sovereignty issues? This timely work examines the doctrine of equitable allocation of transboundary water resources and how this norm can be incorporated into international law.

This is a history of the hydropolitics of the Nile Valley from 1900 to 1988. Attempts to develop the Nile and control its waters are of vital significance to the future of the inhabitants of Egypt, the Sudan, Ethiopia, and East Africa. Acute drought and heavy flooding in the Nile Basin have brought disaster in the past, and the history of the area is the story of human effort to control the precious waters of the river. Written by a distinguished authority in the field, this highly interdisciplinary study will appeal to those interested in the environment, politics, third world development, anthropology, zoology, and economic history.
