This book presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater—a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. The book starts by analysing groundwater in the context of the hydrological cycle. Subsequently, groundwater systems as physical units, with their boundaries mainly defined by geological conditions, are reviewed. The next chapter looks at groundwater as a resource, paying attention, among others, to its quantity and quality, to the differentiation between renewable and non-renewable resources, and to the techniques for withdrawing groundwater. This is followed by a systematic documentation of the quantities of groundwater withdrawn and used around the world, and of the corresponding shares of groundwater in each of the main water use sectors. After that, steadily growing needs for groundwater management interventions are identified, resulting from local human activities and global change (including demography, economic development and climate change). Finally, groundwater resources management is addressed and real-life cases are described that illustrate actions taken and experiences with different issues in different parts of the world. The authors attempted to write this book in such a way that it is accessible to a wider readership than just groundwater professionals. It will also benefit non-groundwater specialists who work in groundwater-related fields (water managers, land use planners, environmentalists, agronomists, engineers, economists, lawyers, and journalists), by broadening their understanding of groundwater and making them aware of the huge variety of groundwater settings. Groundwater specialists will use the book as a convenient reference on the geographical diversity of groundwater. Part of the contents or interpretations offered may even be new to them or enhance their knowledge of some aspects. The many maps, tables, and references will save much time for those who would otherwise have to search elsewhere for basic information on the globe’s groundwater.

This collection of papers is a snapshot of modern hydrogeology in which highly technical methods and approaches sit side-by-side with overlapping legal, social, organisational, institutional and governance considerations. Groundwater is integral to many human and environmental systems. Indeed, there appears to be a growing realisation that some of the most pressing physical problems in the field of hydrogeology - over-abstraction, salinization or pollution - can only really be solved by taking a multi-disciplinary approach to the issues that takes all other related professions into account. Whilst a ‘technical’ solution may be readily deciphered, the larger challenge usually lies in the sustainably-funded and widely-accepted implementation of that measure. This book ranges from discussion and debate on the hot topic of hydraulic fracturing of wells or ‘fraccing’ for shale gas and its potential to disrupt groundwater systems, to the application of highly technical modelling procedures to help solve complex, real world problems. It is a window on the preoccupations of modern hydrogeologists and an insight into the way in which hydrogeological techniques and methods are being holistically adapted to address problems in the real world. This book is targeted at professional hydrogeologists, sociologists, experts in governance, law and policy as well as ecologists and other professionals that nowadays all sit alongside groundwater understanding. The book will also appeal to politicians, resource managers, regulators and others interested in sustainable water supply.

Water scarcity is spreading and intensifying in many regions of the world, with dire consequences for local communities, economies, and freshwater ecosystems. Current approaches tend to rely on policies crafted at the state or national level, which on their own have proved insufficient to arrest water scarcity. To be durable and effective, water plans must be informed by the culture, economics, and varied needs of affected community members. International water expert Brian Richter argues that sustainable water sharing in the twenty-first century can only happen through open, democratic dialogue and local collective action. In Chasing Water, Richter tells a cohesive and complete story of water scarcity: where it is happening, what is causing it, and how it can be addressed. Through his engaging and nontechnical style, he strips away the complexities of water management to its bare essentials, providing information and practical examples that will empower community leaders, activists, and students to develop successful and long-lasting water programs. Chasing Water will provide local stakeholders with the tools and knowledge they need to take an active role in the watershed-based planning and implementation that are essential for water supplies to remain sustainable in perpetuity.

“An urgent and at times terrifying dispatch from a distinguished reporter who has given heart and soul to his subject.”—Hampton Sides When the demographer Robert Malthus (1766–1834) famously outlined the brutal relationship between food and population, he never imagined the success of modern scientific agriculture. In the mid-twentieth century, an unprecedented agricultural advancement known as the Green Revolution brought hybrid seeds, chemical fertilizers, and improved irrigation that drove the greatest population boom in history—but left ecological devastation in its wake. In The End of Plenty, award-winning environmental journalist Joel K. Bourne Jr. puts our race to feed the world in dramatic perspective. With a skyrocketing world population and tightening global grain supplies spurring riots and revolutions, humanity must produce as much food in the next four decades as it has since the beginning of civilization to avoid a Malthusian catastrophe. Yet climate change could render half our farmland useless by century’s end. Writing with an agronomist’s eye for practical solutions and a journalist’s keen sense of character, detail, and the natural world, Bourne takes readers from his family farm to international agricultural hotspots to introduce the new generation of farmers and scientists engaged in the greatest challenge humanity has ever faced. He discovers young, corporate cowboys trying to revive Ukraine as Europe’s breadbasket, a Canadian aquaculturist channeling ancient Chinese traditions, the visionary behind the world’s largest organic sugar-cane plantation, and many other extraordinary individuals struggling to increase food supplies—quickly and sustainably—as droughts, floods, and heat waves hammer crops around the globe. Part history, part reportage and advocacy, The End of Plenty is a panoramic account of the future of food, and a clarion call for anyone concerned about our planet and its people.

December 2004, a tsunami swept over the coasts of Indonesia, Sri Lanka, India, Thailand, and other South Asian countries, leaving hundreds of thousands dead and many more without the resources to rebuild their lives. With casualties as far away as Africa, the aftermath was overwhelming: ships could be spotted miles inland; cars floated in the ocean; legions of the unidentified deadùan estimated 225,000ùwere buried in mass graves; relief organizations struggled to reach rural areas and provide adequate aid to survivors. The Indian Ocean Tsunami: The Global Response to a Natural Disaster is the first comprehensive assessment of the environmental, social, and economic costs of this tragedy. Soon after the tsunami, an international team of geographers, geologists, anthropologists, and political scientists traveled to the most damaged areas to observe and document the tsunami's impact. The Indian Ocean Tsunami draws on data collected by this team. Editors Pradyumna P. Karan and Shanmugam P. Subbiah, along with contributors from multiple disciplines, examine numerous issues that arose in the aftermath of the tsunami, such as inequities in response efforts, unequal distribution of disaster relief aid, and relocation and housing problems. The Indian Ocean Tsunami is organized into several sections, the first of which deals with the ecological destruction of the tsunami. It includes case studies and photographs of the damage in Japan, Indonesia, South India, and other areas. The second section analyzes the economic and social aspects of the aid responses, specifically discussing the role of NGOs in tsunami relief, the strengths and weaknesses of the reconstruction process, and the lessons the tsunami offers to those who are responsible for dealing with future disasters. In the tsunami's aftermath, the inadequacies of governmental and privately funded aid and the challenge of rehabilitating devastated ecosystems quickly became apparent. With this volume, Karan and Suhbiah illuminate the need for the development of efficient, socially and environmentally sustainable practices to cope with environmental disasters. They suggest that education about the ongoing process of recovery will mitigate the effects of future natural disasters. Including maps, photographs, and statistical analyses, The Indian Ocean Tsunami is a clear and definitive evaluation of the tsunami's impact and the world's response to it.

View: 321

Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Therefore, most recent books and papers concentrate mainly on these constituents and only a small number of papers describe the results of groundwater studies on other important water components such as calcium or magnesium. Calcium and magnesium are of great importance to human wellbeing and inadequate intake of either nutrient can impair health. The main objective of this book is to present a selection of studies on calcium and magnesium in groundwater and to highlight their importance for human health. The chapters in this book are written by hydrogeologists and hydrochemists as well as medical doctors and include: methods of investigation of calcium and magnesium in groundwaters, distribution and behaviour of calcium and magnesium in different aquifers, calcium and magnesium in bottled mineral and spring waters, and the significance of calcium and magnesium in waters for human health.
