This book applies interactive perspectives, which have historically mainly been discussed in the context of Western European countries, to case studies on water governance in Asia. It examines how these perspectives can be used to reveal complex and dynamic interactions in water governance in Asia, and how interactions between policies and practices, as well as those between formal institutes and emerging informal institutes, come to pass. In two introductory chapters and seven case studies in Asia (two from China, and each one from Japan, Thailand, the Philippines, Indonesia, and India), the book reveals the interactive forms currently emerging in Asia under hierarchical but often fragmented administrative systems. In addition, it explores emerging hybrid forms of interactive governance, which bring together governmental and non-governmental actors, and discusses how the expected role of government and roles of non-governmental actors could be changed to solve problems in a more cooperative manner. In this context, researchers from outside the locality could play an important role, helping facilitate such forms of interactive governance. The book offers extensive information on the essential features of interactive forms, and on the role of such transdisciplinary approaches, making it a valuable resource not only for scholars and university students, but also for policymakers and grass-roots practitioners directly involved in the interactive process of water governance.

This book tries to answer the question how different communities in such an arid area as the Iranian central plateau could have shared their limited water resources in a perfect harmony and peace over the course of history. They invented some indigenous technologies as well as cooperative socio-economic systems in order to better adapt themselves to their harsh environment where the scarce water resources had to be rationed among the different communities as sustainably as possible. Those stories hold some lessons for us on how to adjust our needs to our geographical possibilities while living side by side with other people. This work gives insight into the indigenous adaptation strategies through the territorial water cooperation, and describes how water can appear as a ground for cooperation. It explains the water supply systems and social aspects of water in central Iran. Topics include the territorial water cooperation, qanat's, the traditional water management and sustainability, the socio-economic context, the sustainable management of shared aquifers system and more.

This book presents a unique collection of up-to-date applications of graphene for water science. Because water is an invaluable resource and the intelligent use and maintenance of water supplies is one of the most important and crucial challenges that stand before mankind, new technologies are constantly being sought to lower the cost and footprint of processes that make use of water resources as potable water as well as water for agriculture and industry, which are always in desperate demand. Much research is focused on graphene for different water treatment uses. Graphene, whose discovery won the 2010 Nobel Prize in physics, has been a shining star in the material science in the past few years. Owing to its interesting electrical, optical, mechanical and chemical properties, graphene has found potential applications in a wide range of areas, including water purification technology. A new type of graphene-based filter could be the key to managing the global water crisis. According to the World Economic Forum's Global Risks Report, lack of access to safe, clean water is the biggest risk to society over the coming decade. Yet some of these risks could be mitigated by the development of this filter, which is so strong and stable that it can be used for extended periods in the harshest corrosive environments, and with less maintenance than other filters on the market. The graphene-based filter could be used to filter chemicals, viruses, or bacteria from a range of liquids. It could be used to purify water, dairy products or wine, or in the production of pharmaceuticals. This book provides practical information to all those who are involved in this field.

The establishment of clean, safe water is one of the major challenges facing societies around the globe. The continued urbanization of human populations, the increasing manipulation of natural resources, and the resulting pollution are driving remarkable burden on water resources. Increasing demands for food, energy, and natural resources are expected to continue to accelerate in the near future in response to the demands of these changing human populations. In addition, the complexity of human activities is leading to a diversity of new chemical contaminants in the environment that represent a major concern for water managers. This will create increased pressure on both water quantity and quality, making it increasingly difficult to provide a sustainable supply of water for human welfare and activities. Although protection of water resources is the best long-term solution, we will also need innovative novel approaches and technologies to water treatment to ensure an adequate superior quality resource to meet these needs. Solving tomorrow's water issues will require unique approaches that incorporate emerging new technologies. Great advances have been made in the area of nanotechnology. Due to their unique physical and chemical properties, nanomaterials are extensively used in antibacterial medical products, membrane filters, electronics, catalysts, and biosensors. Nanoparticles can have distinctly different properties from their bulk counterparts, creating the opportunity for new materials with a diversity of applications. Recent developments related to water treatment include the potential use of carbon nanotubes, nanocompositae, nanospheres, nanofibers, and nanowires for the removal of a diversity of chemical pollutants. By exploiting the assets and structure of these new materials, such as increased surface area, high reactivity, and photocatalytic action, it will be possible to create technologies that can be very efficient at removing and degrading environmental pollutants. Understanding and using these unique properties should lead to innovative, cost-effective applications for addressing the complexities of emerging needs for water treatment and protection. Although still in the early stages, research into the application of nanotechnology shows great promise for solving some of these major global water issues. This comprehensive text describes the latest research and application methods in this rapidly advancing field.

This book focuses on interdisciplinary issues of human health in the changing urban environments of India's largest megacities-Delhi and Mumbai. The authors explore human health concerns related to increased temperatures and air pollution in these cities in a study based on primary data collected through interviews, as well as secondary data on causes of mortality from 2001 to 2012. During this period, the surface temperatures for both megacities were mapped using Landsat Images. The rapidly increasing populations of cities and urban centers alter ecosystem services such as water, air and land cover, with disastrous impacts on health and wellbeing, particularly in megacities. In 2015, polluted air was estimated to have been responsible for 6.4 million deaths worldwide, and it is projected that it will cause between 6 and 9 million deaths per year by 2060. In 2017, outdoor air pollution resulted in 1.2 million deaths in India and brought about a 3% loss in GDP. The increase in population, vehicles, and industries has led to changes in land use and land cover and a rise in city temperatures and air pollution, creating urban heat islands (UHIs). Together, UHIs and air pollution have damaging impacts on human health that range from stress and headache to asthma, bronchitis, and chronic diseases, and even to death. Delhi has been experiencing emergency conditions in terms of environmental health over the past two years. At the same time, both the Delhi and Mumbai urban agglomerations are growing at a rapid pace, and the United Nations has projected that they will be the second and third most populous cities in the world by 2025. In this context, the book offers significant insights into the past patterns and responses to the present global urban health emergencies, and explores sustainable means of combating the problem to enable college and university researchers to develop innovative solutions. Further. It presents trans-disciplinary research that cuts across the WHO Action Plan, the Sustainable Development Goals, the Sendai Framework for Disaster Risk Reduction, and Habitat III to help policymakers gain a better understanding of the global challenges of urban health and wellbeing. The book is especially useful for students and researchers in geography, urban demography, urban studies, environmental studies, health sciences, and policy studies.

UV-Visible Spectrophotometry of Water and Wastewater, Second Edition, represents an update to the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples, the book illustrates how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (e.g., Nitrate, TOC) and simultaneously qualitative information on the global composition of water and its variation. This second edition presents the current methods and applications for water quality monitoring based on UV spectra, including the most recent works and developments. After the introduction of the basics for UV spectrophotometry understanding, the applications of UV measurement are presented, both from the family of chemicals and water quality parameters and from the type of water. Writing from years of experience in the development and applications of UV systems and from scientific and technical works, the authors provide several useful examples showing the great interest of UV spectrophotometry for water quality monitoring. At the end of the book, the UV spectra library of the first edition is updated with dozens of new chemicals of interest.

The book examines a new concern in water quality policy, namely aquatic micropollutants. Micropollutants are chemicals detected in small concentrations in waterbodies today, originating from pharmaceuticals, cosmetics, or detergents, among others. Since the regulation of micropollutants is a fairly new issue, it has been largely neglected in social sciences. However, the search for appropriate solutions is of high political relevance at both the national and international levels, with many open questions arising that concern the most adequate governance structures and steering mechanisms. Solutions suitable for classical, macro-pollutants, such as nutrients, do not necessarily apply to micropollutants because of the diversity of compounds and sources, and for technical, financial, and societal reasons. The book addresses this knowledge gap by investigating the steering mechanisms at hand and their prospect for problem solving. In this regard, the research provides a systematic depiction and comparison of policy designs in place for the reduction of micropollutants in the Rhine basin. Moreover, the study yields insights into the governance structures in place, into actors' responsibilities and constellations, and policy processes regarding micropollutants. The study is furthermore embedded into broader theoretical questions of policy research. More precisely, this research is a contribution to policy analysis that aims to achieve more optimal policy results by providing for a better understanding of the nature of policy designs and the social mechanisms behind the choice of them. Despite the intrinsic aim of policy analysis at contributing to more optimal policy outcomes, there remains a lack of research regarding analytical tools that enable an ex-ante assessment of policy designs' problem-solving abilities. To explore such a research path, this book proposes a novel index of policy comprehensiveness for quantifying the prospective performance of policy designs in alleviating an underlying policy issue, e.g. reducing pollutants in waters. Furthermore, the book uncovers the social mechanisms behind policymaking and turns to the question: In which social settings is it possible to achieve a comprehensive policy design? Compared to purely micro-level explanations, the advantage of the network approach is that it goes beyond the mere aggregation of policy actors' attributes by taking into consideration actors' interdependencies. In order to take the network approach seriously, the study systematically links the structure of a policy network with comprehensive policy designs. Network concepts, such as coalition structure, interconnectedness, and belief similarity, are employed from policy change research here in order to explore the link between structural network characteristics and comprehensive policy design. By studying how network structures affect policy design, the book critically examines the explanatory value of the network approach.
