This Book includes selected papers that has been published in the Water journal Special Issue (SI) on Water Supply and Water Scarcity. Moreover, an overview of the SI is included. The papers selected for publication in the SI include review and research papers on water history, on water management issues under water scarcity regimes, on rainwater harvesting, on water quality and degradation, and on climatic variability impacts on water resources. Overall, the issue identify and highlight the main challenges in water sector, and particularly in management and protection of water resources and in use of alternative (non-conventional) water resources, especially in areas with demographic change and climate vulnerability in order to achieve sustainable and secure water supply. Furthermore, general guidelines and possible solutions for an improved and sophisticated water management system are proposed and discussed, such as the adoption of advanced technological solutions and practices that improve water-use efficiency and the use of alternative water resources, to address the growing environmental and health issues and to reduce the emerging conflicts among water users.
A radical new approach to tackling the growing threat of water scarcity Water is essential to life, yet humankind’s relationship with water is complex. For millennia, we have perceived it as abundant and easily accessible. But water shortages are fast becoming a persistent reality for all nations, rich and poor. With demand outstripping supply, a global water crisis is imminent. In this trenchant critique of current water policies and practices, Edward Barbier argues that our water crisis is as much a failure of water management as it is a result of scarcity. Outdated governance structures and institutions, combined with continual underpricing, have perpetuated the overuse and undervaluation of water and disincentivized much-needed technological innovation. As a result “water grabbing” is on the rise, and cooperation to resolve these disputes is increasingly fraught. Barbier draws on evidence from countries across the globe to show the scale of the problem, and outlines the policy and management solutions needed to avert this crisis.
This volume includes over 30 chapters, written by experts from around the world. It examines the environmental aspects of drought such as groundwater and soil contamination, river low-flow, urban water quality, and desertification. It also examines the effects of climate change and variability on drought, and discusses the differences in groundwater, rainfall, and temperatures and their related effects. It presents analytical modeling for better understanding drought in uncertain and changing climates.
One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones. This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.
Drought Challenges: Livelihood Implications in Developing Countries, Volume Two, provides an understanding of the occurrence and impacts of droughts for developing countries and vulnerable sub-groups, such as women and pastoralists. It presents tools for assessing vulnerabilities, introduces individual policies to combat the effects of droughts, and highlights the importance of integrated multi-sectoral approaches and drought networks at various levels. Currently, there are few books on the market that address the growing need for knowledge on these cross-cutting issues. As drought can occur anywhere, the systemic connections between droughts and livelihoods are a key factor in development in many dryland and agriculturally-dependent nations. Connects the biophysical, social, economic, policy and institutional aspects of droughts across multiple regions in developing world Analyzes policy linkages between government agencies, public institutions, NGOs, the private sector and communities Includes a discussion of gender dimensions of drought and its impacts Presents a multi-sectoral perspective, including the human dimensions of drought in developing countries
Water Scarcity and Sustainable Agriculture in Semiarid Environment: Tools, Strategies and Challenges for Woody Crops explores the complex relationship between water scarcity and climate change, agricultural water-use efficiency, crop-water stress management and modeling water scarcity in woody crops. Understanding these cause- and effect relationships and identifying the most appropriate responses are critical for sustainable crop production. The book focuses on Mediterranean environments to explain how to determine the most appropriate strategy and implement an effective plan; however, core concepts are translational to other regions. Informative for those working in agricultural water management, irrigation and drainage, crop physiology and sustainable agriculture. Focuses on semi-arid crops including olive, vine, citrus, almonds, peach, nectarine, plum, subtropical fruits and others Explores crop physiological responses to drought at plant, cellular and/or molecular levels Presents tool options for assessing crop-water status and irrigation scheduling
“An important story not just about [Texas’s] water history, but also about its social, economic, and political identity” (Western Historical Quarterly). As a changing climate threatens the whole country with deeper droughts and more furious floods that put ever more people and property at risk, Texas has become a bellwether state for water debates. Will there be enough water for everyone? Is there the will to take the steps necessary to defend ourselves against the sea? Is it in the nature of Americans to adapt to nature in flux? The most comprehensive—and comprehensible—book on contemporary water issues, A Thirsty Land delves deep into the challenges faced not just by Texas but also by the nation, as we struggle to find a way to balance the changing forces of nature with our own ever-expanding needs. Part history, part science, part adventure story, and part travelogue, this book puts a human face on the struggle to master that most precious and capricious of resources, water. Seamus McGraw goes to the taproots, talking to farmers, ranchers, businesspeople, and citizen activists, as well as to politicians and government employees. Their stories provide chilling evidence that Texas—and indeed the nation—is not ready for the next devastating drought, the next catastrophic flood. Ultimately, however, A Thirsty Land delivers hope. This deep dive into one of the most vexing challenges facing Texas and the nation offers glimpses of the way forward in the untapped opportunities that water also presents. “A hard look at a hard problem: finding sufficient water to live in a place without much of it. . . . McGraw’s fine book serves as a useful guide. Observers of Western waterways will want to have this on their shelves alongside the likes of Marc Reisner and Charles Bowden.” —Kirkus Reviews “In stark prose that often gleams like a bone pile bleached in the sun, McGraw travels back and forth across Texas to give a free-ranging but deadeye view of the crisis on the horizon.” —Texas Monthly “It’s hard to write about the slow creep of environmental crises like drought without resorting to shock tactics or getting lost in the weeds . . . [McGraw] draws out the conflicts in compelling ways by drilling into the plight of individual water users. Even if you feel no connection to Texas, these stories are relevant to every part of the country.” —Outside “Interviewing both scientific experts and everyday water users, [McGraw] clearly delineates the competing interests, describes political and geological reality, and makes a compelling argument for statewide water policy that utilizes modern technology and fairly weighs parochial needs against the good of the whole.” —Arizona Daily Star, Southwest Books of the Year
In the middle of the Mojave Desert, Las Vegas casinos use billions of gallons of water for fountains, pirate lagoons, wave machines, and indoor canals. Meanwhile, the town of Orme, Tennessee, must truck in water from Alabama because it has literally run out. Robert Glennon captures the irony—and tragedy—of America’s water crisis in a book that is both frightening and wickedly comical. From manufactured snow for tourists in Atlanta to trillions of gallons of water flushed down the toilet each year, Unquenchable reveals the heady extravagances and everyday inefficiencies that are sucking the nation dry. The looming catastrophe remains hidden as government diverts supplies from one area to another to keep water flowing from the tap. But sooner rather than later, the shell game has to end. And when it does, shortages will threaten not only the environment, but every aspect of American life: we face shuttered power plants and jobless workers, decimated fi sheries and contaminated drinking water. We can’t engineer our way out of the problem, either with traditional fixes or zany schemes to tow icebergs from Alaska. In fact, new demands for water, particularly the enormous supply needed for ethanol and energy production, will only worsen the crisis. America must make hard choices—and Glennon’s answers are fittingly provocative. He proposes market-based solutions that value water as both a commodity and a fundamental human right. One truth runs throughout Unquenchable: only when we recognize water’s worth will we begin to conserve it.
Because water access, distribution and quality are the most urgent challenges for societies across the world, this book focuses on the current and future demands and challenges in the areas of water scarcity we may face and possible solutions in terms of technology and management including infrastructure changes that are needed for the future smart cities. Readers of this book shall gain an increased understanding of water supply and its demands and shall learn some of the research trends to overcome global water scarcity and urban growth by creating smart cities.
