The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

Water for People, Water for Life available in PDF, EPUB and Kindle. 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. Visit the United Nation's Water Portal for more information on the report and on the International Year of Freshwater 2003.

This book was released on 2021-09-14. Water available in PDF, EPUB and Kindle. Spanning millennia and continents, a revealing history that “tackles the most important story of our time: our relationship with water in a world of looming scarcity” (Kelly McEvers, NPR Host). "Far more than a biography of its nominal subject ... The book stands as a compelling history of civilization itself." —The Wall Street Journal Book Review Writing with authority and brio, Giulio Boccaletti—honorary research associate at the Smith School of Enterprise and the Environment, University of Oxford—shrewdly combines environmental and social history, beginning with the earliest civilizations of sedentary farmers on the banks of the Nile, the Tigris, and the Euphrates Rivers. Even as he describes how these societies were made possible by sea-level changes from the last glacial melt, he incisively examines how this type of farming led to irrigation and multiple cropping, which, in turn, led to a population explosion and labor specialization. We see with clarity how irrigation’s structure informed social structure (inventions such as the calendar sprung from agricultural necessity); how in ancient Greece, the communal ownership of wells laid the groundwork for democracy; how the Greek and Roman experiences with water security resulted in systems of taxation; and how the modern world as we know it began with a legal framework for the development of water infrastructure. Extraordinary for its monumental scope and piercing insightfulness, Water: A Biography richly enlarges our understanding of our relationship to—and fundamental reliance on—the most elemental substance on earth.

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.
