A compelling look at the challenges of freshwater conservation and management issues facing the United States at the start of the new millennium. Battles have been fought, lives have been lost, countries divided-and all for one reason-water. Freshwater Issues provides a quick education in the basics and essential issues of freshwater management. From water supply and resource information to the role of water in ecosystems, the coverage also provides global water data, examines uncertainties about future water supplies, and addresses technological advances in the development of water resources and environmental safeguards. Thorough treatment is given to water rights, allocation issues, and U.S. water laws and their many regional variations. This is followed by an explanation of the economics of water, from ownership and pricing to social impact and discussions of often-conflicting public, environmental, and private interests. The war over water has just begun.

This book addresses issues related to sources of groundwater pollution such as arsenic, uranium, fluoride and their effects on human health. It discusses extensively the removal of heavy metals, arsenic and fluoride from drinking water. Bioremediation and phyto remediation on biomass productivity are treated in several chapters in the book. The volume highlights leachate characteristics analysed both in the laboratory and in field studies assessing the trace metals in rainwater. This book is a study on the judicious management of natural resources and exposes environmental problems particularly those related to pollution and bioremediation.

This book presents new concepts as well as practical applications and experiences in the field of information technology for environmental engineering. The book has three main focus areas: firstly, it shows how information technologies can be employed to support natural resource management and conservation, environmental engineering, scientific simulation and integrated assessment studies. Secondly, it demonstrates the application of computing in the everyday practices of environmental engineers, natural scientists, economists and social scientists. And thirdly, it demonstrates how the complexity of natural phenomena can be approached using interdisciplinary methods, where computer science offers the infrastructure needed for environmental data collection and management, scientific simulations, decision support documentation and reporting.The book collects selected papers presented at the 7th International Symposium on Environmental Engineering, held in Port Elizabeth, South Africa in July 2015. It discusses recent success stories in eco-informatics, promising ideas and new challenges from the interdisciplinary viewpoints of computer scientists, environmental engineers, economists and social scientists, demonstrating new paradigms for problem-solving and decision-making.

New edition of a NOLS classic; the definitive book on environmental ethics and their relation to managing wildlands An excellent introduction to all relevant federal agencies and legislation Objectively examines various perspectives on difficult ethical questions

Originally published in 1992 as "An Introduction to Wildland Ethics and Management," this fully revised and updated edition is a powerful tool for understanding the challenges facing wilderness in the United States today. Beginning with the premise that land management must be informed by a well-developed wilderness ethic, the authors delve into some of the thorniest problems in environmental ethics, exploring them in clear, straightforward language: What is wilderness? Why should it be protected? Do animals have rights? Do trees? When should wilderness concerns trump individual priorities? The book also provides a fascinating history of the wilderness movement in America and gives a comprehensive survey of the legislation and agency structures that define wildlands management today. Essential reading for land managers, activists, policymakers, or anyone else who cares about the future of wilderness in the United States.

Since the arrival of Europeans about 500 years ago, an estimated 50,000 non-native species have been introduced to North America (including Hawaii). Non-native species figure prominently in our lives, often as ornamentals, sources of food or pests. Although many introduced species are beneficial, there is increasing awareness of the enormous economic costs associated with non-native pests. In contrast, the ecological impacts of non-native species have received much less public and scientific attention, despite the fact that invasion by exotic species ranks second to habitat destruction as a cause of species loss. In particular, there is little information about the ecological impacts of hyper-diverse groups such as terrestrial fungi and invertebrates.

A science symposium, Ecological impacts of non-native invertebrates and fungi on terrestrial ecosystems, held in 2006, brought together scientists from the USA and Canada to review the state of knowledge in this field of work. Additional reviews were solicited following the symposium. The resulting set of review/synthesis papers and case studies represents a cross-section of work on ecological impacts of non-native terrestrial invertebrates and fungi. Although there is a strong focus on Canadian work, there is also significant presentation of work in the northern USA and Europe.

Part travelogue, part history, and part environmental treatise, "Mekong - The Occluding River" is above all else an urgent warning that factors such as pollution, ecological devastation, and the depletion of natural resources are threatening the very existence of the Mekong River. Author Ngo The Vinh combines his vivid travel notes and collection of photographs with a meticulously researched history of the environmental degradation of the Mekong River. Translated from Vietnamese, the best-selling treatise outlines the myriad threats facing the river today. From oil shipments feeding the industrial cities of southwestern China to gigantic hydroelectric dams known as the Mekong Cascades in Yunnan province, China is the worst environmental offender, though the other nations along Mekong's banks behave no better. From Thailand to Laos to Vietnam, hydroelectric dams that threaten the Mekong and its inhabitants are being built at an alarming rate. To save the Mekong, Ngo The Vinh calls upon all the nations that benefit from its life-giving water to observe the "Spirit of the Mekong" in the implementation of all future development projects. To achieve this end, there must be a concerted and sustained commitment to cooperation and sustainability. At this critical cross-roads, we should remind ourselves of the mantra from Sea World San Diego: "Extinction is forever. Endangered means we still have time."

Grand Canyon For Sale is a carefully researched investigation of the precarious future of America's public lands: our national parks, forests, wildlife refuges, monuments, and wildernesses. Taking the Grand Canyon as his key example, and using on-the-ground reporting as well as scientific research, Stephen Nash shows how accelerating climate change will dislocate wildlife populations and vegetation across hundreds of thousands of square miles of the national landscape. In addition, a growing political movement, well financed and occasionally violent, is fighting to break up these federal lands and return them to state, local, and private control. That scheme would foreclose the future for many wild species, which are part of our irreplaceable natural heritage, and also would devastate our national parks, forests, and other public lands. To safeguard wildlife and their habitats, it is essential to consolidate protected areas and prioritize natural systems over mining, grazing, drilling, and logging. Grand Canyon For Sale provides an excellent overview of the physical and biological challenges facing public lands. The book also exposes and shows how to combat the political activity that threatens these places in the U.S. today.

Things have changed. In 1969 when the Convention for the Conservation of the Vicuna was drafted, in an attempt to save the vicuna from its tumbling decline towards extinction, both the science and the philosophy of wildlife conservation were radically different. It is thus a tribute to the prescience of those involved at the time that the rescue plan had, even through the harsh lens of hindsight, a d- tinctly Twenty First Century flavour. After all, it was predicated on the expectation that if vicuna could be saved, they would one day become a valued asset, generating revenue for the human communities that fostered their survival. Embodied in this aspiration are the main structures of modern biodiversity conservation - not only is it to be underpinned by science, but that science should be of both the natural and the social genres, woven into inter-disciplinarity, and thereby taking heed of e- nomics, governance, ownership and the like, alongside biology. In addition, it should include, as a major strut, the human dimension, taking account of the affected constituencies with their varied stakes in alternative outcomes. This c- temporary framework for thinking about biodiversity conservation is inseparable from such wider, and inherently political, notions as community-based conser- tion and ultimately sustainable use.

This book addresses the future of urbanisation on the Galapagos Islands from a systems, governance and design perspective with the competing parameters of liveability, economic and ecological, using the Galapagos as a laboratory for the theoretical and postulative understanding of evolving settlement and habitation. The Galapagos islands are one of the world's most examined and reported examples of a series of naturally evolving ecosystems. The biodiversity of these island ecosystems are the focus of tourism and the image across the world yet human settlement are part of the local ecology. While human intervention is limited, the islands are a distinctive context in which to consider the impact of human habitation as a part of our ecosystems. In this book, authors take the framework of complex adaptive systems (CAS) in which to model systems that grow and evolve, the relations between these various sectors change; systems that get more complex as they evolve. Tested and applied discretely in the two realms of natural and urban, for the first time this text will bring the two together in understanding options for the future of urban settlements on the Galapagos Islands and, by extension, consider how the approach can be used globally in other contexts.

This updated guide provides the latest findings about the biology and ecology of the Gulf of Mexico. It reflects the effects of recent storms and hurricanes, and includes an expanded chapter on sea turtles. Hundreds of detailed drawings introduce you to more than 300 marine creatures commonly found along the beaches and bays of this area. Easy-to-read descriptions explain the taxonomic feeding, mating, and migratory habits of these coastal residents. In addition, this guide tells you about many offshore creatures, such as oysters, shrimp, and lobsters, and the numerous animals that inhabit the subsea oil platforms.

This book provides insight into the instances in which wildlife species can create problems. Some species trigger problems for human activities, but many others need humans to save them and to continue to exist. The text addresses issues faced by economists and politicians dealing with laws involving actions undertaken to resolve the problems of the interaction between humans and wildlife. Here, the words 'problematic species' are used in their broadest sense, as may be appreciated in the short introductions to the various sections. At times, the authors discuss special cases while always extending the discussion into a more general and broad vision. At others, they present real cutting-edge analysis of ecological topics and issues. The book will be of interest to biologists, ecologists and wildlife managers involved in research on wildlife, parks, and environmental management, as well as to government departments and agencies, NGOs and conservation wildlife organizations. Even those in contact with nature, such as hunters, herders, and farmers, will be able to find a great deal of important information. Specific case studies are selected from among the most significant and prevalent cases throughout the world. A total of 26 papers have been selected for this book, written by zoologists, biologists and ecologists. Many have an interdisciplinary approach, with contributions by economists, criminologists, technical specialists, and engineers.

Pollution, resource depletion, habitat management, and climate change are all issues that necessarily transcend national boundaries. Accordingly, they and other environmental concerns have been a particular focus for international organizations from before the First World War to the present day. This volume is the first to comprehensively explore the environmental activities of professional communities, NGOs, regional bodies, the United Nations, and other international organizations during the twentieth century. It follows their efforts to shape debates about environmental degradation, develop binding intergovernmental commitments, and-following the seminal 1972 Conference on the Human Environment-implement and enforce actual international policies.

This book provides an in-depth analysis on community conservation in Mexico. The volume explores vivid examples and case studies that illustrate some of the critical issues at stake, including the participation of local communities in national and global conservation, indigenous and local perceptions of conservation initiatives in Southern Mexico, and challenges in ICCA governance and ecotourism. The book also reviews methodological approaches for understanding and strengthening community conservation, touching upon such topics as community-based biodiversity monitoring and tools for understanding children's perceptions of community conservation. Written by international experts in the field, Community Action for Conservation: Mexican Experiences is a lively and deep-running resource that offers invaluable stories and analyses of the Mexican experience with conservation.

Medina tells us that up to 2% of the urban population in developing countries survives by salvaging materials from waste for recycling, which represents up to 64 million scavengers in the world today. Despite these numbers, we know little about the impact of scavenging on global capitalism development. The author examines its historical evolution and its linkages with formal and informal sector productive activities in capitalist and non-capitalist societies, in case studies from Mexico, Brazil, Colombia, Argentina, Egypt, the Philippines, and India. His new book radically alters popular perceptions on scavenging, demonstrating that many widely-held beliefs are wrong: scavenging is not primarily the activity of the poor nor is it a strictly marginal activity; the economic impact of scavenging is significant and can increase industrial competitiveness; and scavenging can be compatible with a sustainable waste management system. Scavenging represents an adaptive response to poverty, yet at the same time it can be a resource to cities, whose contributions should be recognized and understood.

This book traces national policies behind the efforts of integrating education systems in Europe. In some regions of Europe, such as the Nordic countries, a high level of social integration was achieved by introducing radical comprehensive education systems. By contrast, in countries such as Germany and England, comprehensive education either failed almost completely, or was only partially implemented. Based on a wide-ranging historical analysis, this book offers the first fully comparative explanation of the divergent development of comprehensive education in Europe.

The Environmental Protection Agency is a young and dynamic federal agency facing the challenges of modern environmental protection. The political controversies and social impacts of the agency are immense, involving courts, legislatures, and elected officials, and the effects of its actions are far reaching, affecting every single person in the United States. After a brief history of the agency, chapters describe its organization, programs, controversies, key events, notable people, and impact on society. Topics covered include the Exxon Valdez oil spill, Three Mile Island, and The Clean Air Act, as well as biographies on administrators Carol Browner, William Ruckelhaus, and Anne M. Gorsuch.

Climate change, urban sprawl, abandonment of agriculture, intensification of forestry and agriculture, changes in energy generation and use, expansion of infrastructure networks, habitat destruction and degradation, and other drivers of change occur at increasing rates. They affect patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. Consequently, rapidly changing landscapes present many new challenges to scientists and managers. While it is not uncommon to encounter the terms "global change" and "landscape" together in the ecological literature, a global analyses of drivers of change in forest landscapes, and their ecological consequences have not been addressed adequately. That is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes with emphasis on causes and effects, and challenges faced by researchers and land managers. Initial chapters identify and describe major agents of landscape change: climate, fire, and human activities. The next series of chapters address implications of changes on ecosystem services, biodiversity conservation and carbon flux. A chapter that describes methodologies of detecting and monitoring landscape changes is presented followed by chapter that highlights the many challenges forest landscape managers face amidst of global change. Finally, we present a summary and a synthesis of the main points presented in the book. Each chapter will contain the individual research experiences of chapter authors, augmented by review and synthesis of global scientific literature on relevant topics, as well as critical input from multiple peer reviewers.
