Canada and the United States share the world's longest international border. For those living in the immediate vicinity of the Canadian side of the border, the events of 9/11 were a turning point in their relationship with their communities, their American neighbours and government officials. Borderline Canadianness offers a unique ethnographic approach to Canadian border life. The accounts of local residents, taken from interviews and press reports in Ontario's Niagara region, demonstrate how borders and everyday nationalism are articulated in complex ways across region, class, race, and gender. Jane Helleiner's examination begins with a focus on the "de-bordering" initiated by NAFTA and concludes with the "re-bordering" as a result of the 9/11 attacks. Her accounts of border life reveals disconnects between elite border projects and the concerns of ordinary citizens as well as differing views on national belonging. Helleiner has produced a work that illuminates the complexities and inequalities of borders and nationalism in a globalized world.
Organizing Nature explores how the environment is organized in Canada’s resource-dependent economy. The book examines how particular ecosystem components come to be understood as natural resources and how these resources in turn are used to organize life in Canada. In tracing transitions from "ecosystem component" to "resource," this book weaves together the roles that commodification, Indigenous dispossession, and especially a false nature-society binary play in facilitating the conceptual and material construction of resources. Alice Cohen and Andrew Biro present an alternative to this false nature-society binary: one that sees Canadians and their environments in a constant process of making and remaking each other. Through a series of case studies focused on specific resources – fish, forests, carbon, water, land, and life – the book explores six channels through which this remaking occurs: governments, communities, built environments, culture and ideas, economies, and bodies and identities. Ultimately, Organizing Nature encourages readers to think critically about what is at stake when Canadians (re)produce myths about the false separation between Canadian peoples and their environments.

The proposed new book fills a gap. It will do it admirably. There is no competing book. Present a synthesis of past work, 'connect the dots' so that the work of physical geographers, geomorphologists, physicists and climatologists, hydrologists and related fields can be made available within one book. Be a compendium of all that we know about dunes in the nominated regions. Show how such knowledge can help mankind as new generations face novel and unprecedented challenges.
Nearly one-third of the land area on our planet is classified as arid or desert. Therefore, an understanding of the dynamics of such arid ecosystems is essential to managing those systems in a way that sustains human populations. This second edition of Ecology of Desert Systems provides a clear, extensive guide to the complex interactions involved in these areas. This book details the relationships between abiotic and biotic environments of desert ecosystems, demonstrating to readers how these interactions drive ecological processes. These include plant growth and animal reproductive success, the spatial and temporal distribution of vegetation and animals, and the influence of invasive species and anthropogenic climate change specific to arid systems. Drawing on the extensive experience of its expert authors, Ecology of Desert Systems is an essential guide to arid ecosystems for students looking for an overview of the field, researchers keen to learn how their work fits in to the overall picture, and those involved with environmental management of desert areas.
The concept of fragmentation is explored in this book as it applies to arid, pastoral systems throughout the world. Global significance of the world's vast rangelands is large. Arid and semiarid rangelands make up almost 25% of the earth's landscapes and support more than 20 million people whose livelihoods depend on these lands. It is the home of the planet's last remaining megafauna and many other important species. The case is developed that fragmentation arises from different natural, social and economic conditions worldwide but creates similar outcomes for human and natural systems. With information from nine sites around the world the authors examine how fragmentation occurs, the patterns that result, and the consequences of fragmentation for ecosystems and the people who depend on them for their livelihoods.
The inaction of nation states and international bodies has posed significant risks to the environment. By contrast, cities are sites of action and innovation. In Sustainability, Citizen Participation, and City Governance, contributors researching in the areas of law, urban planning, geography, and philosophy identify approaches for tackling many of the most challenging environmental problems facing cities today. Sustainability, Citizen Participation, and City Governance facilitates two strands of dialogue about climate change. First, it integrates legal perspectives into policy debates about urban sustainability and governance, from which law has typically stood apart. Second, it brings case studies from Quebec into a rare conversation with examples drawn from elsewhere in Canada. The collection proposes humane and inclusive processes for arriving at effective policy outcomes. Some chapters examine governance mechanisms that reconcile clashes of incommensurable values and resolve conflicts about collective interests. Other chapters provide platforms for social movements that have faced obstacles to communicating to a broad public. The collection's proposals respond to drastic changes in urban environments. Some changes are imminent. Others are upon us already. All threaten the present and future well-being of urban communities.
Over the last century, the scale of Canada's domestic disaster response system has grown significantly due to the country's increased capacity for emergency management and the rise in natural hazards. However, there has been no systematic assessment of how effectively this multilevel system, which includes all levels of government and the military, has been integrated, and how efficient this system actually is at responding to high-level disasters. Using in-depth archival analysis and interviews with senior military and civilian officials on the inside, Boots on the Ground provides a detailed examination of Canada's disaster response system. Including policy recommendations focused on the expansion of emergency management networks, the maintenance of Canada's decentralized emergency management system, and disaster response resources for First Nations communities, Boots on the Ground aims to highlight opportunities to improve Canada's urgent disaster response. Boots on the Ground offers helpful lessons for students, policy makers, emergency management practitioners, and military officers, ensuring that readers gain concrete insights into the strategic and efficient implementation of disaster response initiatives.
Prosopis describes the enormous historical importance of these trees as a human food source and reviews the contemporary food science of the fruit derived from these trees. As well, this treatise reviews the native genetic resources of this genus on 4 continents and classical genetic and horticultural techniques that could help stabilize the environment and alleviate human suffering on some of the world's most destitute agro-ecosystems. This book is an essential read for researchers interested in forestry and plant science, environmental science, and functional foods. The legume family (Fabaceae) contains many genera and species that through their nitrogen fixing process provide high protein food and feed for humans and animals. As evidenced by its presence in Death Valley, California, which holds the record for the highest temperatures in the world, these types of plants can thrive in extreme environments.
The countries that make up the MENA region display wide diversity. One of the poorest countries in the world sits alongside two of the wealthiest, whilst the region's natural resources range from immeasurable oil and gas reserves to some of the scantiest natural endowments anywhere in the world. Yet through this diversity runs a common thread: water scarcity. Now, through the impact of human development and climate change, the water resource itself is changing,bringing new risks and increasing the vulnerability of all those dependent on water. Chris Ward and Sandra Ruckstuhl assess the increased challenges now facing the countries of the region, placing particular emphasis on water scarcity and the resultant risks to livelihoods, food security and the environment. They evaluate the risks and reality of climate change in the region, and offer an assessment of the vulnerability of agriculture and livelihoods. In a final section, they explore the options for responding to the new challenges, including policy, institutional, economic and technical measures.
The wild beauty of deserts has always been a source of fascination the world over. Mankind and Deserts 3 - the third and final volume - focuses on wind, frequently present in all deserts, either hot or cold. Wind plays a major role in aridity and landscapes bear numerous forms due to its action, erosion, transportation and surface formations, some discreet and others spectacular, such as vast expanses of towering yardangs. Aeolian dynamics lead to dune formation, simple or associated with sand ridges or ergs, as in the Sahara. Mankind has attempted, to varying degrees of success, to cope with sand accumulation; ignoring aeolian dynamics has led many development projects to failure. This is developed by Yann Callot, a Professor at Lyon University who studied aeolian dynamics in the Sahara. Traditional societies have adapted to live in deserts, establishing vibrant civilizations with original ways of living, managing water resources and creating routes for trade, especially for salt. In a changing environment, useful lessons can be drawn from the genius of mankind s adaptation to such diverse and fragile environments. This is explained by Marc Cote, who was a Professor at Constantine (Algeria) and Aix-en-Provence Universities. From ancient, almost mythical, exploration to modern scientific studies, deserts have come to be better known yet still hold great appeal. This book traces the history of their knowledge while providing a basis for understanding their features and the tools needed for their protection, in an ever-changing world.
Drylands have been cradles to some of the worlda (TM)s greatest civilizations, and contemporary dryland communities feature rich and unique cultures. Dryland ecosystems support a surprising amount of biodiversity. Desertification, however, is a significant land degradation problem in the arid, semi-arid and dry sub-humid regions of the world. Deterioration of soil and plant cover has adversely affected 70% of the worlda (TM)s drylands as a result of extended droughts as well as mismanagement of range and cultivated lands. The situation is likely to worsen with high population growth rates and accompanying land-use conflicts. The contributions to The Future of Drylands a" an international scientific conference held under the leadership of UNESCO a" address these issues and offer practical solutions for combating desertification along with conserving and sustainably managing dryland ecosystems. Major themes include the conservation of dryland biological and cultural diversity and the human dryland interface. This volume documents how our improved understanding of drylands provides insight into the health and future prospects of these precious ecosystems that should help ensure that dryland communities enjoy a sustainable future.
Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990
Drylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources. Originally published in 19990
This book examines the key technologies being deployed in an effort to tap the potential presented by world's deserts for siting large-scale solar power applications, and surveys the feasibility of such projects given the remoteness and the hostility of these environments. Focusing on large scale photovoltaics and concentrating solar thermal power, it explains how the systems work, projects that are being planned, the required scales, and the technical difficulties they need to overcome to function effectively. It then moves on to examine the economics of such projects (including financing) and the social and environmental effects they may have. Illustrated throughout by reference to built or planned projects, and written in a clear, jargon-free style, this is a must-read for anyone interested in the development of large scale solar applications.

Innate Terrain addresses the varied perceptions of Canada’s natural terrain, framing the discussion in the context of landscapes designed by Canadian landscape architects. This edited collection draws on contemporary works to theorize a distinct approach practiced by Canadian landscape architects from across the country. The essays – authored by Canadian scholars and practitioners, some of whom are Indigenous or have worked closely with Indigenous communities – are united by the argument that Canadian landscape architecture is intrinsically linked to the innate qualities of the surrounding terrain. Beautifully illustrated, Innate Terrain aims to capture distinct regional qualities that are rooted in the broader context of the Canadian landscape.

The hot and temperate deserts and their marginal steppe lands comprise one-third of the land surface of the world and are an increasingly critical area for the economic wellbeing of world populations. The remarkable mechanisms of floral, faunal, and human adaptation to the distinct and difficult environment of these arid zones, as well as the potential of modern technology for facilitating adaptation, are described and explained by Walton in the light of our most recent knowledge of the phenomena and processes involved. Beginning with a clarification of the definitions of arid and semi-arid regions and with the delineation of techniques for measuring the degree of aridity in these areas, the author shows that there is wide variation among the arid zones in landscape and climate and that there are numerous local and microclimates within any single arid region. The life cycles of the plants and animals of the arid zones are described and the water resources, including problems of salinity, mineral contamination, and the construction of reservoirs, are examined. Extensive treatment is given to potential agricultural adaptations and to pastoralism as the most widespread response to dry land. A final chapter summarizes attempts at adaptation to prevailing drought and discusses the kinds of future development that the author deems most likely in arid zones. Throughout the book emphasis is placed on specific, detailed analysis, with adequate tables and formulas for in-depth understanding of particular aspects of aridity. Examples from both Old and New Worlds are used to demonstrate the spheres in which progress is being made and to show the mistakes in past and present land use in arid areas. An essential supplement for courses in physical geography, the book will be useful in many area studies and in studies of economic development. "Kenneth Walton" was professor of geography at the University of Aberdeen. He was educated at the University of Edinburgh where he received an M.A. and Ph.D. in Geography and First Class Certificates in Geology and Social Anthropology. Walton has published widely and is the editor of "Map Making and Map Interpretation and Field Studies."

These collections of chapters could provide valuable guidance and scientific content not only for academics, researchers, and students but also for decision-makers in the MENA region and worldwide.
The 11 chapters provide a wide ranging perspective on some of the problems under investigation and several of the systematic approaches currently in use by those concerned with refining the knowledge of the changing environments in the world's drylands during the latter part of the Quaternary. Dealing with a part of the globe that is highly sensitive to small changes of climate, or other stresses such as human impact, this book brings together a set of excellent reviews that will be of great value to students beginning to understand the subject and to paleoenvironmental scientists actively concerned with finding solutions to problems of the region. Additionally, it will be an invaluable archive of important references covering the subject of arid lands palaeoenvironmental research. This volume achieves the aspirations of the International Geological Correlation Programme.
Desertification, land degradation and other geological hazards have resulted from the remobilization of dune areas and climatic change. Recent developments in satellite images of deserts, orbital images of Mars and Venus, and oil and gas discoveries in ancient dunes, have significantly advanced our understanding of desert environments. "The Geomorphology of Desert Dunes" explores how desert dunes are formed, how they change and their environmental importance. Drawing on extensive research from the deserts of South Africa, North America, India, Northern Europe and Australia, the author analyses dune types, patterns, sand seas and sediments, and investigates dune dynamics and processes at different temporal and spatial scales. Investigating the role of climatic change, the author concludes that a better understanding of dune processes and dynamics is vital for effective and appropriate mitigation of environmental problems in arid regions. |
