When Canada's Changing North was first published in 1971, it quickly became a popular and reliable overview of the geography and culture of the Canadian North. In the three decades since it first appeared, great changes have occurred in this huge region that makes up two thirds of Canada's total area. This revised and expanded edition provides a new generation with a comprehensive and up-to-date introduction to the Canadian North and outlines how this region has become increasingly integrated into both the Canadian national fabric and the world.Among the many recent developments explored in Canada's Changing North is the legal recognition of aboriginal rights by the Canadian state, which has led directly to significant increases in their political and economic power. It also examines how economic development, which has long focused on non-renewable natural resources, particularly minerals, has grown to an enormous scale. Development of arctic oil and gas, which hinges on world supplies and national and international politics, has meant major changes across the North. Some of the new national parks in the Canadian North are already under threat from mineral development. Northern tourism has made it possible for a wide variety of affluent visitors to visit hitherto remote areas, affecting the ecology. The final selection, on northern challenges, discusses critical issues such as the impact of climatic change, the social needs (e.g. housing, education) of a rapidly increasing aboriginal population, environmental protection of unique regions, and defence of Arctic sovereignty. Of the sixty-two readings in this edition, forty-one are new.

Today, efforts are being made to rehabilitate badly degraded ecosystems and protect areas which have important ecological value, such as national parks, critical fish and wildlife habitats, natural communities and endangered species. Since human values are an integral part of the decisions to protect or rehabilitate-the goals and objectives for such actions are often unclear. Concepts of "health," "integrity" and "diversity" express important values associated with management actions but they do not provide clear guidelines for these actions. The criteria developed and applied in this book provide guidelines and serve as a road map to anyone involved in ecosystem management-scientists, land managers and policy makers.

Today environmental problems of unprecedented magnitude confront planet earth. The sobering fact is that a whole range of human activities is affecting our global environment as profoundly as the billions of years of evolution that preceded our tenure on Earth. The pressure on vital natural resources in the developing world and elsewhere is intense, and the destruction of tropical forests, wildlife habitat, and other irreplaceable resources, is alarming. Climate change, ozone depletion, loss of genetic diversity, and marine pollution are critical global environmental concerns. Their cumulative impact threatens to destroy the planet's natural resources. The need to address this situation is urgent. More than at any previous moment in history, nature and ecological systems are in human hands, dependent on human efforts. The earth is an interconnected and interdependent global ecosystem, and change in one part of the system often causes unexpected change in other parts. Atmospheric, oceanic, wetland, terrestrial and other ecological systems have a finite capacity to absorb the environmental degradation caused by human behavior. The need for an environmentally sound, sustainable economy to ease this degradation is evident and urgent. Policies designed to stimulate economic development by foregoing pollution controls both destroy the long-term economy and ravage the environment. Over the years, we have sometimes drawn artificial distinctions between the health of individuals and the health of ecosystems. But in the real world, those distinctions do not exist.

From the first appearance of the term in law in the Clean Water Act of 1972 (US), ecological integrity has been debated by a wide range of researchers, including biologists, ecologists, philosophers, legal scholars, doctors and epidemiologists, whose joint interest was the study and understanding of ecological/biological integrity from various standpoints and disciplines. This volume discusses the need for ecological integrity as a major guiding principle in a variety of policy areas, to counter the present ecological and economic crises with their multiple effects on human rights. The book celebrates the 20th anniversary of the Global Ecological Integrity Group and reassesses the basic concept of ecological integrity in order to show how a future beyond catastrophe and disaster is in fact possible, but only if civil society and ultimately legal regimes acknowledge the necessity to consider ecointegrity as a primary factor in decision-making. This is key to the support of basic rights to clean air and water, for halting climate change, and also the basic rights of women and indigenous people. As the authors clearly show, all these rights ultimately depend upon accepting policies that acknowledge the pivotal role of ecological integrity.

"Sprawl" - the spread of development from urban centers into the countryside - is recognized as one of the most serious threats to watershed functionality and health. Introduction to Watershed Development: Understanding and Managing the Impacts of Sprawl presents a logical framework to measure, minimize, and manage the problem of development. From the viewpoint of understanding the responses of watersheds to sprawl, this book addresses issues such as: how water bodies are linked to the land, what the horizon issues and problems are in watershed management, which surveying approaches can be used to monitor the change to watersheds, and how new, water-sensitive developments can be planned. Exploring what landscape architecture approaches cna be used to mitigate the problems of development, Introduction to Watershed Development is Robert L. France's distinctive and extremely well-informed perspective on watershed management, culled from the author's many years of research, scholarship, consulting, and teaching. -- from back cover.

Concepts of ecological integrity have recently been proposed to facilitate enhanced protection of biological and ecological resources against the threat of human activities. The promotion of ecological integrity as a basis for public policy and decision making stems from scientists and others concerned about the threats of human activities to ecosystems and species, and from philosophers attempting to derive a more suitable ethic to guide the relationships between humans and the non-human environment. Although ecological integrity has been proposed as a norm for public policy and decision making, the concept is relatively new and therefore the underlying scientific and philosophical rationales have not been fully developed. This book offers a number of perspectives to stimulate and inform future discussion on the importance and consequences of ecological integrity for science, morality and public policy. Audience: Environmental professionals, whether academic, governmental or industrial, or working in the private consultancy sector. Also suitable as an upper-level reference text.

The ecological sciences are a diverse array of major scientific disciplines. They grew from minor sciences, with little status in 1900, and now occupy crucial areas of research bearing on the future of our planet. This book describes a century of growth and development. A dramatic century-long rise in the status of ecological knowledge was accompanied by the rise of professional ecological organizations, the establishment of university faculties, and the creation of government agencies advising on conservation, natural resources, and the prevention of pollution. Like all sciences, ecology continues to yield new findings and surprising revelations. New technologies now address existential challenges facing our world. This book, documenting the rise of ecology, is an inspiring history portending an important role in the twenty-first century. Key Features: The author is the acknowledged authority on the history of ecology The content is familiar to members of the Ecological Society of America but has not previously been assembled into a single narrative Appropriate for a course in the history of ecology Provides a broad perspective on ecology Related Titles: Egerton, F.

Voices for the Watershed is a unique look at the singular and ecologically inter-connected region of the Great Lakes-St Lawrence watershed, including the headwater and upland regions. With contributions from experts from the United States, Quebec, and Ontario, this book offers an accessible introduction to the issues affecting the quality of our most essential and precious of natural resources - clean, fresh water - from headwater regions downstream to the Great lakes, the St Lawrence river, and ultimately the watershed's outflow to the sea. With thoughtful words and evocative photography, Voices for the Watershed promotes understanding and examines ecological problems, describing positive environmental actions and projects as well as ongoing concerns over the effects of pollution on wildlife and human health. The underlying themes throughout are that the drainage basins and ecosystems are under siege - from reckless land use decisions, soil erosion, acid rain, and massive habitat destruction - but that the situation is not hopeless. The authors feel strongly that education about the environmental threats - in the classroom and public forums - is essential to effecting positive change, and that conservation actions by citizen groups and individuals can be a driving force in effecting substantial reforms regarding environmental legislation and practices. Voices for the Watershed is an eye-opening look at not only the problems but possible solutions to help protect and preserve this resilient natural resource on which so many depend.

Policies promoting Toronto as a global city and provincial economic engine have been seen as beneficial to the development of all of Ontario, yet much of the province has borne significant environmental, social, economic, and political costs as a result of one city's growth. Contributors to this volume call for a radical re-imagining of public policy at local, provincial, and federal levels, that accounts for Ontario's overlooked regions. Beyond the Global City presents a kaleidoscopic view of the province - the rich fields and small towns of the southwest, the productive agricultural lands of rural Huron County, historic Kingston and the Upper St Lawrence, the social and cultural diversity of the Ottawa valley, the near mythical woodlands and waters of Muskoka and Georgian Bay, and the heavily exploited coasts and waters of the Great Lakes - to provide a deeper understanding of its various communities. In a series of regional studies, contributors describe each area's distinctive qualities and challenges and offer recommendations about what is needed to move them forward in a more equitable and sustainable way. Two initial historical chapters lay the framework for the regional discussions, while cross-cutting and integrated chapters analyze the state of natural and cultural heritage and current development theory provincially, offering guidance for the future.

On Hunger focuses on the interface between food and public health and on the flawed regulations intended to protect us. Food not only represents nourishment for the body; it also possesses other valuable aspects that are protected by international legal instruments. Westra argues for the importance of effecting radical changes: to protect and improve the present system of food production and distribution. Starting from several reports produced by the FAO and the WHO, Westra argues for the need of a complete and radical re-evaluatio of current practices and systems in order to meet the obligation of the international community to prevent hunger. There is a particular emphasis on the problems facing the poor in the third world, but also the different but equally grave problems of those in developed countries, where the emphasis remans on corporate profit rather than on the protection of individuals, as present dangers affect all, starting from the children of all ages. Most of the existing literature on hunger and food does not address the harm that current practices inflict on people globally. Laura Westra’s On Hunger focuses on the interface between food and public health and on the flawed regulations intended to protect us. Food not only represents nourishment for the body; it also possesses other valuable aspects that are protected by international legal instruments. Westra argues for the importance of effecting radical changes: to protect and improve the present system of food production and distribution. This timely book explores every aspect of this challenge, from the impact of climate change, the role of the media and obligations to future generations. Westra also considers the legality of financial contributions on the part of agribusiness to political figures and campaigns, as well as their intrusion in the drafting of bills and regulatory regimes. Finally, the book highlights more positive developments,including the expansion of the remit of the International Criminal Court to include environmental crimes. On Hunger offers an original take on this increasingly important issue and will provide fascinating reading for scholars and students in law, philosophy and human rights.
