The Congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the problem posed by the environmental toxin arsenic, with significant societal impact. The Congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and other specific issues on arsenic across a broader environmental realm. The Biennial Congress "Arsenic in the Environment" was first organized in Mexico City (As2006) followed by As2008 in Valencia (Spain), As2010 in Tainan (Chinese Taiwan), As2012 in Cairns (Australia), As2014 in Buenos Aires (Argentina) and As2016 in Stockholm (Sweden). The 7th International Congress As2018 was held July 1-6, 2018, in Beijing, P. R. China and was entitled Environmental Arsenic in a Changing World. The Congress addressed the broader context of arsenic research aligned on the following themes: Theme 1: Arsenic Behaviour in Changing Environmental Media Theme 2: Arsenic in a Changing Agricultural Ecosystem Theme 3: Health Impacts of Environmental Arsenic Theme 4: Technologies for Arsenic Immobilization and Clean Water Blueprints Theme 5: Sustainable Mitigation and Management Arsenic in drinking water (mainly groundwater) has emerged as an issue of global health concern. During last decade, the presence of arsenic in rice, possibly also other food of plant origins, has attained increasing attention. This is particularly true in the Asian countries, where the use of high arsenic groundwater as source of irrigation water and drinking water has been flagged as severe health concern. This has been accentuated by elevating arsenic concentrations in deep groundwater recharged from shallow high arsenic groundwater, which may have further detrimental effects on public health. Notably, China has been in the forefront of research on arsenic biogeochemical cycling, health effects of arsenic, technologies for arsenic removal, and sustainable mitigation measures. The Congress has attracted professionals involved in different segments of interdisciplinary research on arsenic in an open forum, and strengthened relations between academia, research institutions, government and non-governmental agencies, industries, and civil society organizations to share an optimal ambience for exchange of knowledge.

One of the core areas of study in civil engineering concerns water that encompasses fluid mechanics, hydraulics and hydrology. Fluid mechanics provide the mathematical and scientific basis for hydraulics and hydrology that also have added empirical and practical contents. The knowledge contained in these three subjects is necessary for the optimal and equitable management of this precious resource that is not always available when and where it is needed, sometimes with conflicting demands. The objective of Fluid Mechanics, Hydraulics, Hydrology and Water Resources for Civil Engineers is to assimilate these core study areas into a single source of knowledge. The contents highlight the theory and applications supplemented with worked examples and also include comprehensive references for follow-up studies. The primary readership is civil engineering students who would normally go through these core subject areas sequentially spread over the duration of their studies. It is also a reference for practicing civil engineers in the water sector to refresh and update their skills.

This book, which was first published in 1992 and then updated in 2007, provides a tool for dealing with the legal and institutional aspects of water resources management within national contexts and at the level of transboundary water resources. Like its two previous editions, it seeks to cover all aspects that need to be known in order to attain good water governance, but it provides updates concerning developments since 2007. These relate, inter alia, to the following: - the "greening" of water law, which calls for the progressive integration of environmental law principles into domestic and international water law; - the adoption, by the International Law Commission in 2008, of the Draft Articles on the Law of Transboundary Aquifers, and subsequent developments; - the emergence of the right to water as a self-standing human right; - the adoption of domestic water laws supporting integrated water resources management (IWRM) and enhanced public participation in planning and decision making; - the integration into these laws of tools facilitating adaptive water management as a response to climate variability and change; - progress in the implementation of EU law; - recent international agreements and judicial decisions; - efforts of regional organizations other than the EU to steer cooperation in the management of transboundary water resources and the harmonization of national laws; - institutional mechanisms for the management of transboundary water resources (surface and underground). Unique in its scope and nature, the book identifies the legal and institutional issues arising in connection with water resources management and provides guidelines for possible solutions in a manner accessible to a wide range of readers. Thus, it is a useful reference for lawyers and non-lawyers - engineers, hydrologists, hydrogeologists, economists, sociologists - dealing with water resources within government institutions, river basin commissions, international organizations, financing institutions and academic institutions, among other things, and also for students of disciplines related to water resources.

Water utilities are the main instrument for countries to achieve universal service coverage. In pursuing universal service coverage, water utilities have turned to pro-poor water services to extend water services in low-income areas. This thesis discusses the use of pro-poor water services by water utilities in Kenya, with the intention of highlighting the dimensions of the approach that require attention of policy makers and practitioners when engaging with the concept. Based on the analysis of the technologies, financial and organisational arrangements associated with the pro-poor concept, this thesis shows that the use of pro-poor strategies allows water utilities to reduce the risks of servicing low-income areas while still claiming to fulfil their mandate of providing access to all in a commercially viable manner. The analysis also shows that rather than a decision of the water utility, the choice for pro-poor strategies emerges as the result of a consensus or compromise between the different actors that constitute the broader institutional environment in which water utilities operate. The thesis concludes that while pro-poor water services may serve the interests of water utilities and other stakeholders, in the absence of well-directed subsidies and proper monitoring they will not result in low-income households benefiting from more affordable and reliable access to water.

The spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the Dinder and Rahad basins in Sudan is confronted by the lack of climatic, hydrological and ecological data. This book investigated the impacts of land degradation on the Dinder and Rahad hydrology and morphology, and interlinkage to the ecohydrological system of the Dinder National Park (DNP) in Sudan. It used an ensemble of techniques to improve our understanding of the hydrological processes and LULC changes in these basins. This included long-term trend analysis of hydroclimatic variables, LULC changes analysis, field measurements, rainfall-runoff modelling, hydrodynamic and morphological modelling of the Dinder river and its floodplain, with special focus on the Mayas wetlands. Moreover, this research is the first study to investigate the eco-hydrology of the DNP. It is expected that the results of the study will be beneficial to all stakeholders concerned and support decision-making processes for better management of water resources and ecosystem conservation in the area and possibly beyond.

Climate change is likely to continue to have severe impacts, including sea level rise. At the same time, population increase and development imperatives create additional pressure on available water resources. These changes are problematic for the Mediterranean coastal areas and especially the Nile Delta coast. Particular focus of this study is on salinization of groundwater resources in the Nile Delta Aquifer (NDA) due to saltwater intrusion. To assess current conditions and develop future adaptation strategies for the NDA, a 3D model simulating regional variable-density groundwater flow and coupled salt transport was constructed based on available data set, using the SEAWAT code. A method for identification of the most representative model has been developed, based on testing different simulation periods during which the NDA has 'evolved' from completely fresh groundwater conditions to conditions representative for the year 2010.This model was then applied to analyze possible future NDA conditions under several predefined scenarios of sea level rise and groundwater extraction. This analysis indicated that the impacts from further extractions of groundwater on availability of fresh groundwater in the aquifer are more significant compared to those from sea level rise. Furthermore, three different adaptation measures and their impacts in the Sharkeya Nile Delta governorate were tested. It was shown that that changing crop types and irrigation practices towards water saving options seem to be more promising than artificial recharge with injection wells or extraction and usage of brackish groundwater after desalination. The developed model is useful for further Water-Food Nexus studies.

Water is an irreplaceable and transient resource, which crosses political boundaries in the form of rivers, lakes, and groundwater aquifers. The collapse of the Soviet Union in 1991, led to the birth of fifteen countries including the five Central Asian republics, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. When the USSR ceased to exist, so did the centralised Soviet resource distribution system that managed the exchange and allocation of water, energy, and food supplies. A whole new set of international relations emerged, and the newly formed Central Asian governments had to redefine the policies related to the exchange and sharing of their natural resources. This book analyses the role of state power in transboundary water relations. It provides an in-depth study of the evolution of interstate relations in Central Asia in the field of water from 1991-2015. Taking as a case study the planned construction of the Rogun and Kambarata dams in Tajikistan and Kyrgyzstan, the author examines various forms of overt and covert power shaping interstate relations and the way hegemonic and counter-hegemonic measures are put in place in an international river basin. He argues that the intimate correlation between the concepts of power and hegemony can offer key insights to the analysis and understanding of transboundary water relations. While the analytical focus is placed on state power, the book demonstrates that hegemonic and counter-hegemonic tactics represent the ways in which power is wielded and observed. Offering fresh theoretical interpretations to the subjects of power and counter-hegemony in the Aral Sea basin, this book puts forward the original circle of hydro-hegemony, an analytical framework in which the various forms of power are connective in the function of hegemony. It will be of interest to scholars in the field of water and environmental politics and Central Asian Studies.

While water is an increasingly scarce resource, most existing methods to allocate it are neither economically nor environmentally efficient. In these circumstances, water markets offer developed countries a form of regulatory response capable of overcoming many of the shortcomings of current water management. The debate on water markets is, however, a polarized one. This is mostly a result of the misunderstanding of the roles played by governments in water markets. Proponents mistakenly portrayed them as leaving governments, for the most part, out of the picture. Opponents, in turn, understand commodification of water and administration by public agencies as incompatible. Casado Perez argues that both sides of the debate overlook that water markets require a deeper and more varied governmental intervention than markets for other goods. Drawing on economic theories of regulation based on market failure, she explains the different roles governments should play to ensure a well-functioning water market, and concludes that only the visible hand of governments can ensure the success of water markets. Casado Perez proves her case by examining case studies of California and Spain to assess the success of their water markets. She explores why water markets were more extensively institutionalized in California than in Spain in the first ten years since their introduction and how the role of governments in each case study impacted water market operation. This unique analysis of governmental roles in water markets, alongside qualitative studies of California and Spain, offers valuable guidance to understand environmental markets and to face the challenges presented by water management in regions with periodical droughts.

In 2017 four rivers in Aotearoa New Zealand, India, and Colombia were given the status of legal persons, and there was a recent attempt to extend these rights to the Colorado River in the USA. Understanding the implications of creating legal rights for rivers is an urgent challenge for both water resource management and environmental law. Giving rivers legal rights means the law can see rivers as legal persons, thus creating new legal rights which can then be enforced. When rivers are legally people, does that encourage collaboration and partnership between humans and rivers, or establish rivers as another competitor for scarce resources? To assess what it means to give rivers legal rights and legal personality, this book examines the form and function of environmental water managers (EWMs). These organisations have legal personality, and have been active in water resource management for over two decades. EWMs operate by acquiring water rights from irrigators in rivers where there is insufficient water to maintain ecological health. EWMs can compete with farmers for access to water, but they can also strengthen collaboration between traditionally divergent users of the aquatic environment, such as environmentalists, recreational fishers, hunters, farmers, and hydropower. This book explores how EWMs use the opportunities created by giving nature legal rights, such as the ability to participate in markets, enter contracts, hold property, and enforce those rights in court. However, examination of the EWMs unearths a crucial and unexpected paradox: giving legal rights to nature may increase its legal power, but in doing so it can weaken community support for protecting the environment in the first place. The book develops a new conceptual framework to identify the multiple constructions of the environment in law, and how these constructions can interact to generate these unexpected outcomes. It explores EWMs in the USA and Australia as examples, and assesses the implications of creating legal rights for rivers for water governance. Lessons from the EWMs, as well as early lessons from the new 'river persons,' show how to use the law to improve river protection and how to begin to mitigate the problems of the paradox.

The contingent valuation of water is one of the key components when wanting to implement proposals for integrated water management in mountain basins. Management of Hydrological Systems (MHS), is one of the great challenges that the Sustainable Development Goals (SDGs) currently demand. Mainly in mountain basins with fragile ecosystems that face strong pressures such as poverty, urban and population growth, low water supply and sanitation, and climate change. Management of Hydrological Systems aims for sustainable water management, through contingent water valuation, showing the reader in a didactic way the procedure to follow in mountain basins. This book offers a complete characterization of the main problems affecting this type of basin, as well as the detailed procedure of the contingent valuation of water, which directly involves users. As such, this work is offered in relation to this urgent need for practical guidance demanded by society (SDGs), and is based on practical and real examples, rather than theoretical constructions, from places where these issues have not been widely addressed. The text is recommended as a way forward, not only for water resource managers and decision- and policymakers but also for students and teachers who wish to implement this MHS guide.
