This edited volume provides a critical discussion of particular trends that are widely recognised to influence water management by comparing them with what is actually happening in the field. Among others, these trends include water security, adaptive or integrative management, and the water-energy-food nexus, which are often presented as essential means to reaching more sustainable and resilient water use. However, the extent to which these trends have managed to structure concrete practices in water management remains uncertain. Informed by empirically grounded research, each chapter of this work engages with a particular approach, concept or theory. Together, they provide a nuanced picture of trends in water management that require universal remedies and global norms.

The book presents a critical and comparative analysis of the hydropolitical landscape of African transboundary river basins which, for much of the past century, have been affected by water scarcity. River and lake basins can become a source of tension and conflict due to a complicated mix of environmental, demographic, diplomatic, historical and geopolitical factors. This book, however, specifically focuses on the important, and often under looked, role played by scarcity in generating or exacerbating conflicts in shared river basins. Asserting that transboundary river basins tie states into a web of interdependence, this book raises awareness of how water scarcity, or the depletion of water resources, complicates this relationship as nations are forced to look beyond their own borders to meet the demand for water to satisfy multiple needs. Taking a comparative approach, it examines three shared basins: the Orange-Senqu, the Nile and the Niger River basins. While situated in different regions, all three basins are marked by serious environmental challenges that are detrimental to combustible hydropolitics over such shared water resources and they provide fascinating insights into the links between climate variability and change, water resources, human security, conflict, adaptation and regime capacity. Overall, this book argues that conflict over transboundary resources can be prevented given the establishment of norms, rules, and the role of external actors that help regulate state behaviour and control their impacts. This book will be of great interest to students and scholars of water resource management, hydropolitics, environmental conflict, resource scarcity and international relations. It will also be of interest to policymakers involved in transboundary water resource governance.

Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief. Stopping or reversing the trend requires management interventions. The North China Plain serves as an example. A management system is set up for a typical county. It contains three components: monitoring, decision support based on modelling, and implementation in the field. Besides all monitoring data, the decision support module contains an irrigation calculator, a box model, and a distributed groundwater model to project the outcomes of different water allocation scenarios. In view of grain security, a solution combines an adaptation of the cropping system with imports of surface water from the South. The Open Access book does not only describe the problem and the path to its solution. It also gives access to nine manuals concerning methods used. They include computer programs and the game Save the Water. The Chinese experience should be of considerable interest to other regions in the world which suffer from over-pumping of aquifers.

Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book includes practical case studies from around the world, including locations such as Africa, Australia, China, India, the Middle East, the United States, and more. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change

This book employs a suite of remotely sensed products and advanced technologies to provide the first comprehensive space-based sensing of Lake Victoria, the world's second largest freshwater lake that supports a livelihood of more than 42 million people, modulates regional climate, but faces myriads of challenges. Proper understanding of the lake and changes in its physical dynamics (e.g., water level, shorelines and areal dynamics) resulting from the impacts of climate variation and climate change as well as anthropogenic (e.g., hydropower and irrigation) is important for its management as well as for strategic development before, during and after climate extremes (e.g., floods and droughts) in order to inform policy formulations, planning and mitigation measures. Owing to its sheer size, and lack of research resources commitment by regional governments that hamper its observations, however, it is a daunting task to undertake studies on Lake Victoria relying solely on in-situ "boots on the ground" measurements, which are sparse, missing in most cases, inconsistent or restricted by governmental red tapes. To unlock the potentials of Lake Victoria, this book argues for the removal of obsolete Nile treaties signed between Britain, Egypt and Sudan in the 1920s and 1950s, which prohibits its utilization by the upstream countries. The book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. In a unique cross-disciplinary approach, the Book articulates the various climatic impacts and explanations from natural and anthropogenic origins, which affected Lake Victoria and its vicinity, including the drastic increase and depletion of water level in the Lake and dams, floods and droughts, water quality/security, crop health, food security, and economic implications. With no exception as in his many publications, Joseph L. Awange used data analysis methodologies including filtering, adjustment theory, and robust statistics, to quantify the hydrologic and other parameters, and their estimated uncertainties. The Book is recommended for readers from a diverse disciplines, including physical and social sciences, policy, law, engineering, and disaster management. Professor C.K. Shum, Ohio State University.

The over-exploitation of groundwater and marked changes in climate over recent decades has led to unacceptable declines in groundwater resources. Under the likely scarcity of available water resources in the near future, it is critical to quantify and manage the available water resources.

Is safe and sustainable water and sanitation for all an unaffordable pipedream? This book surveys the worldwide development of water and sewage services and the challenges in meeting Sustainable Development Goal 6 (SDG6) along with climate change, population growth and urbanisation. It explores the reasons why current SDG6 progress is failing, including weak policy implementation, staff shortages and inadequate funding, as well as the limited impact of aid funding. The author contends that despite a series of innovations, debt finance remains too small to address needs of developing economies. Therefore, instead of advocating new funding, this book proposes addressing the funding gap through technological innovation and more efficient management and procurement through a series of examples that have challenged traditional assumptions. After four decades of good intentions, SDG6 is making a difference in monitoring shortfalls for the first time, allowing for more effective responses. This book outlines the role of innovation in hardware development, procurement and installation, and discusses how network management and operations can most effectively address funding gaps. The potential for savings is considerable, if effectively replicated. New approaches are driving forward affordable resilience, including nature-based solutions such as upstream habitat enhancement to retain water and improve downstream water quality; the circular economy, including water, nutrient, energy and heat recovery from wastewater; and demand management. This book will be of great value to scholars, policy makers and practitioners interested in the global finance of sustainable water and sanitation.

This book introduces the latest research regarding the adsorption of heavy metals, toxic ions, and organic compounds at the interfaces of water/minerals, such as mineralogical characterizations, surface chemistry, and modification of natural minerals as adsorbents, as well as the adsorption of cations, anions, and organic compounds in water. Presenting findings by the authors and their co-workers, the book helps readers grasp the principals and benefits of using minerals for water treatment, as well as the advanced technologies in the area developed over last 30 years, especially the last 10 years.

The focus of municipalities has been on the supply of sufficient water quantities to the public with less attention paid to water quality. The deteriorating quality of raw water sources necessitates increased attention to water quality with professional scientists playing a central role at municipalities and water boards together with professional engineers. With many stringent regulations on the quality of drinking water and recreational water bodies, the young municipal chemist needs a handy manual to assist in the often neglected and complicated field of municipal water management. Grounded in Science, Introduction to Municipal Water Quality Management not only links theory and regulations in practice but also offers simple numerical examples to better understand the rules and encourage a quantitative application to everyday problems. Developed from a series of lectures between 2015 and 2019, Introduction to Municipal Water Quality Management will give young professionals the confidence to analyse their results and apply their knowledge in a numerical fashion.

This book expands the body of scientific knowledge on research and solutions for alternative water systems. It addresses a wide variety of water management issues in buildings, ranging from the technical possibilities, hydraulic and financial efficiency, and public acceptance of decentralized water systems, to their impact on sewage systems. Climate changes, population growth, and progressive urbanization are the main causes of the growing interest in alternative sources of water around the world. Decentralized systems are seen not only as solutions that can effectively save water, but also as systems that can operate partially or completely independently of centralized suppliers. With these aspects in mind, the main focus of this book is on showcasing a new approach to water management at the building scale. The findings and insights presented here will support the development of future technical guidelines for using alternative water systems in urban areas - an aspect that is particularly important since, in many European countries, these systems are only very rarely used.

The past half century has seen an evolution in thinking from 'flood control' to 'flood risk management', recognizing that risk results from both hazard and vulnerability. Rather than rely only on engineering structures to reduce flood magnitude or extent, recent policies emphasize avoiding construction in flood-prone areas (or moving people from floodplains), reducing impacts on exposed populations through early warning systems, and insurance to aid in recovery. Implementing this new approach faces many challenges but also offers opportunities for synergies, as described in this book for a range of large floodplain rivers and smaller urban streams across North America and Europe. This book is unique in presenting the voices of those on the front lines of implementing a new paradigm in flood risk management, each river with a unique set of challenges and opportunities derived from its specific geography as well as differences in governance between the American and European contexts.

This book presents state-of-the-art, essential methods and tools for flood risk assessment and management. The costs of damage caused by extreme weather events, among which floods are a major category, are rapidly rising, both globally and across Europe. The scope and scale of flood episodes point to the need for comprehensive proposals, including the implementation of flood protection measures in areas exposed to flood risk. This book is dedicated to flood damage assessment, and addresses the management of social, economic and environmental damage. It develops a general methodology for flood risk assessment and presents a range of effective flood protection methods in keeping with the objectives of flood risk management. As such, it offers a valuable resource for young researchers, academics, lecturers and water management practitioners alike.

Describing the natural state of eight important lakes in Asia and the human impact on these lake ecosystems, this book offers a valuable reference guide. Over the past several decades the Aral Sea, Dead Sea, Lake Balkhash and other major lakes in Asia have undergone significant changes with regard to their size, water level, chemical composition, and flora and fauna. Most of these changes resulted from the loss of water from tributaries (now used for irrigation farming) or increasing consumption in local industries and households. However, significant human impacts may have begun as early as 2000 years ago. In addition to the three lakes mentioned above, Lake Sevan (Armenia), the Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan), Lake Issyk-Kul (Kyrgyzstan), and Lake Lop Nur (China) are discussed as the most prominent examples of changing lake ecosystems. In contrast, an example of an almost pristine lake ecosystem is included with the report on Lake Uvs Nuur (Mongolia). For each lake, the book summarizes its origin and early geological history, and reconstructs its natural state and variability on the basis of proxy records from drilled or exposed lake sediments that have accumulated since the last ice age. The frequently observed reductions in lake level and size during most recent decades led often to significant environmental impacts in the respective lake catchments including vegetation deterioration, soil erosion and badland formation, soil salinization or the formation of sinkholes.
