Although it is widely understood that energy and water are the world’s two most critical resources, their vital interconnections and vulnerabilities are less often recognized. This farsighted book offers a new, holistic way of thinking about energy and water—a big picture approach that reveals the interdependence of the two resources, identifies the seriousness of the challenges, and lays out an optimistic approach with an array of solutions to ensure the continuing sustainability of both. Michael Webber, a leader and teacher in the field of energy technology and policy, explains how energy and water supplies are linked and how problems in either can be crippling for the other. He shows that current population growth, economic growth, climate change, and short-sighted policies are likely to make things worse. Yet, Webber asserts, more integrated planning with long-term sustainability in mind can avert such a daunting future. Combining anecdotes and personal stories with insights into the latest science of energy and water, he identifies a hopeful path toward wise long-range water-energy decisions and a more reliable and abundant future for humanity.
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate The Dietary Reference Intakes (DRIs) are quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. This new report, the sixth in a series of reports presenting dietary reference values for the intakes of nutrients by Americans and Canadians, establishes nutrient recommendations on water, potassium, and salt for health maintenance and the reduction of chronic disease risk. Dietary Reference Intakes for Water, Potassium, Sodium, Chloride, and Sulfate discusses in detail the role of water, potassium, salt, chloride, and sulfate in human physiology and health. The major findings in this book include the establishment of Adequate Intakes for total water (drinking water, beverages, and food), potassium, sodium, and chloride and the establishment of Tolerable Upper Intake levels for sodium and chloride. The book makes research recommendations for information needed to advance the understanding of human requirements for water and electrolytes, as well as adverse effects associated with the intake of excessive amounts of water, sodium, chloride, potassium, and sulfate. This book will be an invaluable reference for nutritionists, nutrition researchers, and food manufacturers.
This book provides a novel cross-disciplinary approach to water, demonstrating the role water plays in shaping human lives. It uses anthropological information about water in Kenya, Wales and Spain to show how what water does in those areas has influenced the way that people can be with it.
The explorer and author of Walking the Americas and Walking the Himalayas delivers “a bold travelogue, illuminating great swathes of modern Africa” (Kirkus Reviews). Starting in November 2013 in a forest in Rwanda—where a modest spring spouts a trickle of clear, cold water—writer, photographer, and explorer Levison Wood set forth on foot, aiming to become the first person to walk the entire length of the fabled river. He followed the Nile for nine months, over 4,000 miles, through six nations—Rwanda, Tanzania, Uganda, South Sudan, the Republic of Sudan, and Egypt—to the Mediterranean coast. Like his predecessors, Wood camped in the wild, foraged for food, and trudged through rainforest, swamp, savannah, and desert, enduring life-threatening conditions at every turn. He traversed sandstorms, flash floods, minefields, and more, becoming a local celebrity in Uganda, where a popular rap song was written about him, and a potential enemy of the state in South Sudan, where he found himself caught in a civil war and detained by the secret police. As well as recounting his triumphs, like escaping a charging hippo and staving off wild crocodiles, Wood’s gripping account recalls the loss of Matthew Power, a journalist who died suddenly from heat exhaustion during their trek. As Wood walks on, often joined by local guides who help him to navigate foreign languages and customs, Walking the Nile maps out African history and contemporary life. “Woods emerges as a dutiful and brave guide.”—Los Angeles Times “Many have attempted this holy grail of an expedition—so I admire Lev’s determination and courage to pull this off.”—Bear Grylls “A brilliant book.”—Financial Times
This work provides those involved in water purification research and administration with a comprehensive resource of methods for analyzing water to assure its safety from contaminants, both natural and human caused. The book first provides an overview of major water-related issues in developing and developed countries, followed by a review of issues of sampling for water analysis, regulatory considerations and forensics in water quality and purity investigations. The subsequent chapters cover microbial as well chemical contaminations from inorganic compounds, radionuclides, volatile and semi-volatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, as well as potential terrorist-related contamination. The last chapter describes the Grainger prize-winning filter that can remove arsenic from water sources and sufficiently protect the health of a large number of people. Covers the scope of water contamination problems on a worldwide scale Provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants Describes the filter that won the $1 million Grainger prize and thereby highlighting an important approach to remediation
The United Nations General Assembly and the Human Rights Council recognised the human right to water in 2010. This formal recognition has put the issue high on the international agenda, but by itself leaves many questions unanswered. This book addresses this gap and clarifies the legal status and meaning of the right to water through a detailed analysis of its legal foundations, legal nature, normative content and corresponding State obligations. The human right to water has wide-ranging implications for the distribution of water. Examining these implications requires putting the right to water into the broader context of different water uses and analysing the linkages and competition with other human rights that depend on water for their realisation. Water allocation is a highly political issue reflecting societal power relations, with current priorities often benefitting the well-off and powerful. Human rights, in contrast, require prioritising the most basic needs of all people. The human right to water has the potential to address these underlying structural causes of the lack of access to water rooted in inequalities and poverty by empowering people to hold the State accountable to live up to its human rights obligations and to demand that their basic needs are met with priority.
Formally acknowledging water as a human right could encourage the international community and governments to enhance their efforts to satisfy basic human needs and to meet the Millennium Development Goals. But critical questions arise in relation to a right to water. What would be the benefits and content of such a right? What mechanisms would be required for its effective implementation? Should the duty be placed on governments alone, or should the responsibility also be borne by private actors? Is another 'academic debate' on this subject warranted when action is really what is necessary? Without claiming to prescribe the answers, this publication clearly and carefully sets out the competing arguments and the challenges.
The world's freshwater resources are coming under growing pressure through such environmental hazards as human waste, urbanization, industrialization, and pesticides. The problems are exacerbated through drought in many parts of the world. The improvement of the water quality itself and access to it have been major concerns for politicians and development agencies for over a decade. First officially formulated at the Rio Earth Summit of 1992, they have been restated or expanded since then. The UN Millennium Declaration of 2000 transformed general guidelines into specific targets. The international community pledged "to halve by 2015 the proportion of people who are unable to reach, or to afford, safe drinking water" and "to stop the unsustainable exploitation of water resources, by developing water management strategies at the regional, national and local levels, which promote both equitable access and adequate supplies." Thus, ten years after Rio it is time to take stock. Based on the collective inputs of 23 United Nations agencies and convention secretariats, this Report offers a global overview of the state of the world's freshwater resources. It is part of an on-going assessment process to develop policies and help with their implementation as well as to measure any progress towards achieving sustainable use of water resources. Generously illustrated with more than 25 full-color global maps and numerous figures, the report reviews progress and trends and presents seven pilot case studies of river basins representing various social, economic and environmental settings: Lake Titicaca (Bolivia, Peru); Senegal river basin (Senegal, Mali, Mauritania, Guinea); Seine Normandy (France); Lake Peipsi/Chudskoe (Estonia, Russia); Ruhuna basin (Sri Lanka); Greater Tokyo region (Japan); and Chao Phraya (Thailand). It assesses progress in 11 challenge areas, including health, food, environment, shared water resources, cities, industry, energy, risk management, knowledge, valuing water and governance. Proposing methodologies and indicators for measuring sustainability, it lays the foundations for regular, system-wide monitoring and reporting by the UN, together with the development of standardized methodologies and data. With its comprehensive maps, glossary, references and coverage of a broad range of themes and examples of real-world river basins, the UN World Water Development Report will no doubt prove to be a most valuable reference work.
