Envisioning the Agenda for Water Resources Research in the Twenty-First Century by Water Science and Technology Board,Division on Earth and Life Studies,National Research Council Pdf

In this century, the United States will be challenged to provide sufficient quantities of high-quality water to its growing population. Water is a limiting resource for human well-being and social development, and projections of population growth as well as changing social values suggest that demands for this resource will increase significantly. These projections have fueled concerns among the public and water resources professionals alike about the adequacy of future water supplies, the sustainability and restoration of aquatic ecosystems, and the viability of our current water resource research programs and our institutional and physical water resource infrastructures. With the goal of outlining a roadmap to guide policymakers, the Water Science and Technology Board (WSTB) held a series of discussions at several of its meetings in 1998-2000 about the future of the nation's water resources and the appropriate research needed to achieve their long-term sustainability. From those discussions, the board produced this report, the objectives of which are to: draw attention to the urgency and complexity of water resources issues facing the United States in the twenty-first century; broadly inform decision makers, researchers, and the public about these issues and challenges; identify needed knowledge and corresponding water resources research areas that should be emphasized immediately and over the long term; and describe ways in which the setting of the water research agenda, the conduct of water research, and investments devoted to such research should be improved in the next few decades. This report discusses major research questions related to the critical water issues that face the nation. It lays out an interdisciplinary research portfolio for the next 20 years and recommends agenda-setting processes that can maximize the nation's ability to prioritize and conduct water resources research.

Water as an Inescapable Risk by Anja du Plessis Pdf

The book presents an interdisciplinary systematic evaluation of increasing water stress and scarcity over the globe and specifically South Africa. South Africa is used as the prime example as the country is experiencing similar water challenges in terms of availability and quality as most regions across the globe. Water availability is predominantly used to illustrate water scarcity however, continued degradation of the world’s freshwater resources, by a multitude of natural and anthropogenic factors, have consequently exacerbated water stress and scarcity due to it being of insufficient quality for various uses. The increase of water scarcity through both natural and anthropogenic factors has in turn led to water being viewed as an increasing risk within all spheres. Water as a source of conflict has come to the forefront especially within regions which struggle to meet the increasing demands from different water users and trying to achieve future sustainability of the resource. The increase of water scarcity and stress as well as the continued pressure of population and economic growth has brought various new challenges into play. This book focuses on water as an increasing risk over the globe and specifically South Africa by reviewing both water availability and quality, evaluating water as a global and national risk. The book concludes by focusing on current limitations, necessary strategic actions as well as possible policy-related changes which may be required to adapt to future water challenges and to lessen water as an increasing risk.

Advancing the Science of Climate Change by National Research Council,Division on Earth and Life Studies,Board on Atmospheric Sciences and Climate,America's Climate Choices: Panel on Advancing the Science of Climate Change Pdf

Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

Water Availability and Management in Mexico by Elena María Otazo-Sánchez,Amado Enrique Navarro-Frómeta,Vijay P. Singh Pdf

This book presents several complex case studies related to water management and planning in the context of pollution, growing demands, and global climate change in Mexico, but which are also relevant for other countries in Latin America. These concerns are of critical importance for policymakers who are coping with multiple conflicting interests. Water availability in Mexico is polarized, with abundant rainfall and large rivers in the south, and desert-like conditions in the north. The central region, which is the most industrialized, is overpopulated. Mexico City pours millions of cubic meters of “blackwater” into the northern valley daily and receives its clean water from the south. To address these unsustainable conditions, the world's 4th biggest water treatment plant went into operation in 2018. The water infrastructure and governance must satisfy the demands of all sectors, including agricultural, urban, and economic activities. At the same time, water resources are affected by drought, and climate change puts constraints on the supply. As such, regulation and monitoring are important when it comes to adherence to agreed plans and priorities. The book is divided into four sections. 1: Water Availability discusses quantitative aspects, such as supply, methods of calculation, and fracking. 2: Water Quality highlights pollution risks and diagnosis of water resources. 3: Water Allocation examines the sectoral demands and vulnerability due to unsustainable irrigation. 4: Water Governance and Management focuses on laws, urban rules, national parks, planning, and integrated water resources management, among other topics. The chapters include illustrative case studies in Mexico, such as basins, cities, reservoirs, and aquifers, water supply demand assessment, planning, and management.

Integrated Groundwater Management by Anthony J Jakeman,Olivier Barreteau,Randall J Hunt,Jean-Daniel Rinaudo,Andrew Ross Pdf

The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

Quality Criteria for Water by United States. Environmental Protection Agency Pdf

The Federal Water Pollution Control Act Amendments of 1972 require the Administrator of the Environmental Protection Agency to publish criteria for water quality accurately reflecting the latest scientific knowledge on the kind and extent of all identifiable effects on health and welfare which may be expected from the presence of pollutants in any body of water, including ground water. Proposed Water Quality Criteria were developed and a notice of their availability was published on October 26, 1973 (38 FR 29646). This present volume represents a revision of the proposed water quality criteria based upon a consideration of comments received from other Federal agencies, State agencies, special interest groups and individual scientists. Standards and their criteria are given for over 54 chemicals.

Liquid Assets by Jill Boberg Pdf

Most writings linking demographic trends to water availability often look only at population-growth effects, treating water supplies as static and population as increasing, inexorably leading to a water-availability crisis. This report's more holistic view of the interaction between demographics and water resources considers more demographic and local water-availability variables. It focuses on conditions in developing countries, where these factors intersect with the fewest socioeconomic resources to mediate.

Confronting the Nation's Water Problems by National Research Council,Division on Earth and Life Studies,Water Science and Technology Board,Committee on Assessment of Water Resources Research Pdf

In order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.
