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 Jornada Basin LTER is located in the Chihuahuan Desert, the largest in North America. This region of south central New Mexico has a history of nearly 100 years as the basis for scientific research. This work gives a thorough, encompassing review of the tremendous array of observations resulting from experiments conducted in this ecosystem. Beginning with thorough descriptions of the most salient features of the region, the book then reviews a wide range of archived and active data sets on a diversity of biotic and abiotic features. It next presents a syntheses of important topics including livestock grazing and remediation efforts. A concluding chapter provides a synthesis of the principles that have emerged from this body of work, and how these relate to the broader fields of ecology and natural resource management. It concludes with recommendations for future research directions. The insightful views expressed in this volume should guide management of arid landscapes globally. This is the sixth volume in the Long Term Ecological Network Series.

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.
This edited volume is devoted to the examination of the implications of the inevitable changes wrought by global change on the welfare and livelihoods of tens of millions of people who live in dryland regions. Global change is more than just climate change and the ramifications of changing trade patterns (geopolitical and economic aspects), the shift to the market economy, demographic factors (population growth, urbanization and re-settlement), receive attention here. Land use change specialists, policy makers and natural resource management agencies will find the book very useful. Chapters focus on examples that are drawn from a number of sources including previously unpublished studies on the impact of climate change, markets and economics on pastoralist and dryland farming households. The key focus is to provide readers with insights into the real world implications of change (including an analysis of the drivers of change) on these vulnerable groups within dryland societies. The role of humans as agents of these changes is canvassed. A regional analysis of the world's drylands is also performed including those in Australia, Argentina, India, North America, China, North Africa, Central Asia and Southern Africa.
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.
There is no question that Africa is endowed with abundant natural resources of different magnitudes. However, more than a decade of high commodity prices and new hydrocarbon discoveries across the continent has led countless international organizations, donor agencies, and non-governmental organizations to devote considerable attention to the potential of natural resource-based development. Natural Resource-Based Development in Africa places a particular emphasis on the actors that help us understand the extent to which resources could be transformed into broader developmental outcomes. Based on a wide variety of primary sources and fieldwork, including in-person interviews and participant observations, this collection contributes to both scholarly and policy discussions around the governance and economic development roles of local entrepreneurs, transnational firms, civil society groups, local communities, and government agencies in Africa's natural resource sectors. Natural Resource-Based Development in Africa explores the impact that these actors have on regional trends such as resource nationalism and local procurement policies as well as grassroots-related issues such as poverty, livelihoods, gender equity, development, and human security.
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.
Rising at 11,750 feet in the Sangre de Cristo range and snaking 926 miles through New Mexico and Texas to the Rio Grande, the Pecos River is one of the most storied waterways in the American West. It is also one of the most troubled. In 1942, the National Resources Planning Board observed that the Pecos River basin ""probably presents a greater aggregation of problems associated with land and water use than any other irrigated basin in the Western U.S."" In the twenty-first century, the river's problems have only multiplied. Bitter Waters, the first book-length study of the entire Pecos, traces the river's environmental history from the arrival of the first Europeans in the sixteenth century to today. Running clear at its source and turning salty in its middle reach, the Pecos River has served as both a magnet of veneration and an object of scorn. Patrick Dearen, who has written about the Pecos since the 1980s, draws on more than 150 interviews and a wealth of primary sources to trace the river's natural evolution and man's interaction with it. Irrigation projects, dams, invasive saltcedar, forest proliferation, fires, floods, flow decline, usage conflicts, water quality deterioration - Dearen offers a thorough and clearly written account of what each factor has meant to the river and its prospects. As fine-grained in detail as it is sweeping in breadth, the picture Bitter Waters presents is sobering but not without hope, as it also extends to potential solutions to the Pecos River's problems and the current efforts to undo decades of damage. Combining the research skills of an accomplished historian, the investigative techniques of a veteran journalist, and the engaging style of an award-winning novelist, this powerful and accessible work of environmental history may well mark a turning point in the Pecos's fortunes.
This book provides in-depth information on Caatinga's geographical boundaries and ecological systems, including plants, insects, fishes, amphibians, reptiles, birds, and mammals. It also discusses the major threats to the region's socio-ecological systems and includes chapters on climate change and fast and large-scale land-use changes, as well as slow and small-scale changes, also known as chronic human disturbances. Subsequent chapters address sustainable agriculture, conservation systems, and sustainable development. Lastly, the book proposes 10 major actions that could enable the transformation of Caatinga into a place where people and nature can thrive together. "I consider this book an excellent example of how scientists worldwide can mobilize their efforts to propose sound solutions for one of the biggest challenges of modern times, i.e., how to protect the world's natural ecosystems while improving human well-being. I am sure this book will inspire more research and conservation action in the region and perhaps encourage other groups of scientists to produce similar syntheses about their regions." Russell Mittermeier, Ph.D. Executive Vice-Chair, Conservation International
This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions. The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors' synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.
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.
WINNER OF THE STANFORD DOLMAN TRAVEL WRITING AWARD 2019 One third of the earth's land surface is desert, much of it desolate and inhospitable. What is it about this harsh environment that has captivated humankind throughout history? Travelling to five continents over three years, William Atkins discovers a realm that is as much internal as physical. From the contested borderlands of the USA to Australia's nuclear test zones, via Nevada's riotous Burning Man festival and the ancient monasteries of Egypt, he illuminates the people, history, nature and symbolism of these remarkable but often volatile places.
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."
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.
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. |
