The various safety organizations working on drinking water all warn about unhealthy constituents, as well as elements that can cause corrosion or scaling on pipes and installations. However, drinking water may also provide a substantial portion of the daily mineral intake, especially for the elderly and children, or those at risk of deficiencies due to unhealthy eating habits or starvation. Thus, a holistic approach to drinking water is presented in this book and the scope is extended from standards for undesirable substances to the basic mineral composition of water, examining 22 nutrient elements and ions and 21 toxic substances. The function of the nutrients in the body, symptoms of deficiency and overload, and advantages of the minerals from drinking water are presented, as well as symptoms of toxic elements from drinking water. The authors also suggest healthy ranges of minerals and mineral ratios for drinking water. The book offers a valuable resource for the health evaluation of drinking waters, for private well owners, public water producers and safety organizations alike.

This volume presents the outcome of an Agriculture Workshop organized by the Gulf Research Centre Cambridge (GRCC) and held at Cambridge University, UK during the Gulf Research Meeting 11-14 July 2012. Co-directed by the editors, the workshop, entitled "Environmental Cost and Changing Face of Agriculture in the Gulf States" was attended by participants from Australia, Bahrain, India, Kuwait, Oman, Saudi Arabia, Turkey, UAE, UK and Morocco. These scientists, educators, researchers, policy makers and managers share their experience in agriculture in the Gulf States, with the aim of helping to improve agriculture production and thus bridge the gap between local production and the food import. The papers gathered here were presented at the workshop and have all passed through rigorous peer review by renowned scientists. The diverse papers present various aspects of agriculture production in the evolving face of climate change and dwindling water resources in the region. The book covers topics such as the prospects of agriculture in a changing climate; the potential of climate-smart agriculture; the impact of food prices, income and income distribution on food security; improved efficiency in water use; challenges in using treated wastewater in agriculture; investment in foreign agriculture and agricultural research and development. The papers span the nations of the Gulf Cooperation Council, with specific case studies set in Oman, Bahrain and Kuwait.
This book provides an essential overview of ecotechnologies (also known as green infrastructure or nature-based solutions) which are considered to be relatively resilient to variations in stormwater and wastewater inflow. In particular, it focuses on various types of constructed wetlands, biofilters and ponds. Stormwater flows are inherently variable, due to rainfall events and fluctuations in loading. This variability has significant effects on the performance of treatment systems, but has rarely been specifically addressed in design manuals, performance assessments or modelling. The book's respective chapters cover the main contaminant categories of interest (nutrients, faecal microbes, metals and emerging contaminants) and their removal processes using ecotechnologies, addressing urban, industrial and agricultural applications. In addition, they review modelling tools with the potential to improve our understanding of flow variability and the ability to simulate and predict responses to it.
This book focuses on land and disaster governance in Asian countries. The Asian region has become increasingly vulnerable to natural disasters, including floods, cyclones, storms, earthquakes, drought, typhoons and tsunamis. Further, as a result of unsustainable changes being made in patterns of land use, catchment and coastal zones, increasing population density, migration patterns, and the spread of consumer culture across countries, the impact of natural disasters has increased manifold. The book addresses two major concerns in this field. Firstly, it discusses topics intended to raise awareness among all stakeholders of the critical aspects of disaster management in the context of Asia. Secondly, it calls upon policymakers, researchers, academics, practitioners, private enterprises and civil society organizations, as well as all those who have been, are and will be affected by natural disasters to search for innovative and novel approaches to reducing risk and managing disasters.
This book pursues a comprehensive, multidisciplinary approach in order to analyze the relationship between water and food security. It demonstrates that most of the world’s economies lack sufficient water resources to secure their populations’ food requirements and are thus virtual importers of water. One of the most inspiring cases, which this book is rooted in, is Italy: the third largest net virtual water importer on earth. The book also shows that the sustainability of water depends on the extent to which societies recognize and take into account its value and contribution to agricultural production. Due to the large volumes of water required for food production, water and food security are in fact inextricably linked. Contributions from leading international experts and scholars in the field use the concepts of virtual water and water footprints to explain this relationship, with an eye to the empirical examples of wine, tomato and pasta production in Italy. This book provides a valuable resource for all researchers, professionals, policymakers and everyone else interested in water and food security.
Contamination of the different components of environment through industrial and anthropogenic activities have guided new eras of research. This has lead to development of strategies/methodologies to curtail/minimize environmental contamination. Research studies conducted all over the globe established that bioremediation play a promising role in minimizing environmental contamination. In the last decade, phytoremediation studies have been conducted on a vast scale. Initial research in this scenario focused on screening terrestrial plant species that remove contaminants from soil and air. Later, scientific community realized that water is a basic necessity for sustaining life on earth and quality of which is getting deteriorated day by day. This initiated studies on phytoremediation using aquatic plants. Role of aquatic plant species in cleaning water bodies was also explored. Many of the aquatic plant species showed potential to treat domestic, municipal and industrial wastewaters and hence their use in constructed wetlands for treating wastewaters was emphasized. The present book contains five chapters. First two chapters provide information about types of contaminants commonly reported in wastewaters and enlists some important and well studied aquatic plant species known for their potential to remove various contaminants from wastewater. Subsequent chapters deal with mechanisms involved in contaminant removal by aquatic plant species, and also provide detailed information about role of aquatic plant species in wetlands. Potential of constructed wetlands in cleaning domestic and industrial wastewaters has also been discussed in detail. The strategy for enhancing phytoremediation capacity of plants by different means and effectiveness of phytoremediation technology in terms of monitory benefits has been discussed in last chapter. Last chapter also emphasizes the future aspects of this technology. Â
Scholarship on the right to water has proliferated in interesting and unexpected ways in recent years. This book broadens existing discussions on the right to water in order to shed critical light on the pathways, pitfalls, prospects, and constraints that exist in achieving global goals, as well as advancing debates around water governance and water justice. The book shows how both discourses and struggles around the right to water have opened new perspectives, and possibilities in water governance, fostering new collective and moral claims for water justice, while effecting changes in laws and policies around the world. In light of the 2010 UN ratification on the human right to water and sanitation, shifts have taken place in policy, legal frameworks, local implementation, as well as in national dialogues. Chapters in the book illustrate the novel ways in which the right to water has been taken up in locations drawn globally, highlighting the material politics that are enabled and negotiated through this framework in order to address ongoing water insecurities. This book reflects the urgent need to take stock of debates in light of new concerns around post-neoliberal political developments, the challenges of the Anthropocene and climate change, the transition from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs), as well as the mobilizations around the right to water in the global North. This book is essential reading for scholars and students of water governance, environmental policy, politics, geography, and law. It will be of great interest to policymakers and practitioners working in water governance, as well as the human right to water and sanitation.

Using renewable fuels and materials, drinking clean water and food, and breathing safe air are major issues for a sustainable world. This book reviews biodiesel production from microalgae, a promising energy source that does not compete with food production. Several advanced techniques to clean polluted waters, such as electrochemistry, ferrites photocatalysis and low-cost filtration are presented. Chapters also show various living organisms used as bioindicators of toxic metals. Decreasing ecotoxicity of pesticides using suitable surfactants is reviewed. The last chapter evidences new pollutants in urban soils, halogenated polycyclic aromatic hydrocarbons.
Urban water and wastewater systems have an inherent vulnerability to both manmade and natural threats and disasters including droughts, earthquakes and terrorist attacks. It is well established that natural disasters including major storms, such as hurricanes and flooding, can effect water supply security and integrity. Earthquakes and terrorist attacks have many characteristics in common because they are almost impossible to predict and can cause major devastation and confusion. Terrorism is also a major threat to water security and recent attention has turned to the potential that these attacks have for disrupting urban water supplies. There is a need to introduce the related concept of Integrated Water Resources Management which emphasizes linkages between land-use change and hydrological systems, between ecosystems and human health, and between political and scientific aspects of water management. An expanded water security agenda should include a conceptual focus on vulnerability, risk, and resilience; an emphasis on threats, shocks, and tipping points; and a related emphasis on adaptive management given limited predictability. Internationally, concerns about water have often taken a different focus and there is also a growing awareness, including in the US, that water security should include issues related to quantity, climate change, and biodiversity impacts, in addition to terrorism. This presents contributions from a group of internationally recognized experts that attempt to address the four areas listed above and includes suggestions as to how to deal with related problems. It also addresses the new and potentially growing issue of cyber attacks against water and waste water infrastructure including descriptions of actual attacks, making it of interest to scholars and policy-makers concerned with protecting the water supply.
The recent European Council Directive 114/08 requested the EU Member States to perform an assessment aimed at the identification and designation of the so-called European Critical Infrastructures (ECI). Every analysis of the results of the "first round" of identifications and designations has only taken into account the numbers of ECIs effectively designated, consequently leaving aside all of the other elements related to this important path towards a harmonized vision of the "European Security". This work, with its unprecedented approach, focuses on the elements that have maximized or frustrated the ambitious European objectives and on the issues that might have prevented the directive reaching its full potential. Furthermore, the study offers an in-depth perspective on the lessons learned - including those that can be learned from the US pre-post 9/11 CIP policies - as well as an assessment of the state of play of the Member States after the implementation of the directive, together with predictions for future challenges.
This book addresses most of the environmental impacts of sand mining from small rivers The problems and solutions addressed in this book are applicable to all rivers that drain through densely populated tropical coasts undergoing rapid economic growth. Many rivers in the world are drastically being altered to levels often beyond their natural resilience capability. Among the different types of human interventions, mining of sand and gravel is the most disastrous one, as the activity threatens the very existence of river ecosystem. A better understanding of sand budget is necessary if the problems of river and coastal environments are to be solved.

To keep drinking water safe involves more than following the letter of the law. This book introduces a comprehensive perspective and a proactive step-by-step approach to maintaining drinking water quality in distribution systems, and aids in delivering verifiably safe and economical water to end users. This second edition is updated throughout, and reflects the latest processes for improving drinking water quality in water systems and bringing those systems into compliance with the Lead and Copper Rule, the Disinfection By-Products Rule, and the Total Coliform Rule. It also presents the latest techniques for calming discolored water issues, keeping microbiological growth and biofilm formation in check, and preventing the formation of pinhole leaks in copper pipes. The book also aids in determining side effects of treatment chemicals, achieving simultaneous compliance with multiple regulations, and optimizing treatment chemical dosages. A typical water distribution system is complex and chaotic with varying piping configurations, water flows, chemical reactions, and microbiological activity. It is, therefore, no surprise that monitoring and assessing water quality can be a daunting task. Water Distribution System Monitoring: A Practical Approach for Evaluating Drinking Water Quality simplifies this task by providing the tools for well-defined and measurable control of water quality.
Water Crises and Governance critically examines the relationship between water crises and governance in the face of challenges to provide water for growing human demand and environmental needs. Water crises threaten the assumptions and accepted management practices of water users, managers and policymakers. In developed and developing world contexts from North America and Australasia, to Latin America, Africa and China, existing institutions and governance arrangements have unintentionally provoked water crises while shaping diverse, often innovative responses to management dilemmas. This volume brings together original field-based studies by social scientists investigating water crises and their implications for governance. Contributors to this collection find that water crises degrade environments, place untenable burdens on stakeholders, and produce or exacerbate social conflict, undermining ecological and social conditions that sustain effective collaboration. At the same time, water crises can promote institutional change that "resets" governance, promoting unusual and creative responses appropriate for local contexts. The studies in this volume provide evidence that, while water crises pose serious threats to environments and societies, they also provide opportunities to learn from experience and recraft water governance with coherent visions of more ecologically and socially sustainable futures. This volume was originally published as a special issue of Society & Natural Resources.
The increase in GHG gases in the atmosphere due to expansions in industrial and vehicular concentration is attributed to warming of the climate world wide. The resultant change in climatic pattern can induce abnormalities in the hydrological cycle. As a result, the regular functionality of river watersheds will also be affected. This Brief highlights a new methodology to rank the watersheds in terms of its vulnerability to change in climate. This Brief introduces a Vulnerability Index which will be directly proportional to the climatic impacts of the watersheds. Analytical Hierarchy Process and Artificial Neural Networks are used in a cascading manner to develop the model for prediction of the vulnerability index.
This volume provides a comprehensive perspective on geomorphic approaches to management of lowland alluvial rivers in North America and Europe. Many lowland rivers have been heavily managed for flood control and navigation for decades or centuries, resulting in engineered channels and embanked floodplains with substantially altered sediment loads and geomorphic processes. Over the past decade, floodplain management of many lowland rivers has taken on new importance because of concerns about the potential for global environmental change to alter floodplain processes, necessitating revised management strategies that minimize flood risk while enhancing environmental attributes of floodplains influenced by local embankments and upstream dams. Recognition of the failure of old perspectives on river management and the need to enhance environmental sustainability has stimulated a new approach to river management. The manner that river restoration and integrated management are implemented, however, requires a case study approach that takes into account the impact of historic human impacts to the system, especially engineering. The river basins examined in this volume provide a representative coverage of the drainage of North America and Europe, taking into account a range of climatic and physiographic provinces. They include the 1) Sacramento (California, USA), 2) San Joaquin (California), 3) Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota, USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA), 7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10) Danube (Romania), and 11) Volga (Russian Federation) Rivers. The case studies covered in these chapters span a range of fluvial modes of adjustment, including sediment, channel, hydrologic regime, floodplains, as well as ecosystem and environmental associations.
