Over the past two decades, the oil sands region of northeastern Alberta has been the site of unprecedented levels of development. Alberta's Lower Athabasca Basin tells a fascinating story of how a catastrophic ice age flood left behind a unique landscape in the Lower Athabasca Basin, one that made deposits of bitumen available for surface mining. Less well known is the discovery that this flood also produced an environment that supported perhaps the most intensive use of boreal fo...

In its first edition, Soils established itself as the leading textbook in the fields of pedology and soil geomorphology. Expanded and fully updated, this second edition maintains its highly organized and readable style. Suitable as a textbook and a research-grade reference, the book's introductory chapters in soil morphology, mineralogy, chemistry, physics and organisms prepare the reader for the more advanced treatment that follows. Unlike its competitors, this textbook devotes considerab...

Forest soils form the foundation that underpins the existence of all forests. This book encapsulates soil ecology and functioning in northern forests, focusing on the effects of human activity and climate change. The authors introduce the fundamental principles necessary for studying forest soils, and explain the functioning and mutual influence of all parts of a forest soil ecosystem. A chapter is dedicated to each of soil acidity and heavy metal pollution, elevated carbon dioxide, nitrog...

Bioremediation is the use of microorganisms' metabolism to degrade waste contaminants (sewage, domestic, and industrial effluents) into non-toxic or less toxic materials by natural biological processes. Remediation through fungi—or mycoremediation—has multifarious possibilities in applied remediation engineering and the future of environmental sustainability. Fungi have the biochemical and ecological capability to degrade environmental organic chemicals and to decrease the risk associated ...

This book covers an overview of research on sediment textures, sedimentary structures, sediment composition and bioturbation structures including other aspects of tidal sedimentation. The analytical results for the tidal river sedimentation and essential aspects of relevant field studies along the entire stretch of the Thakuran River are being presented in this book. Filled with interesting results obtained from minutely observations, this book brings together outstanding facts of the tida...

A major history of early Americans' ideas about conservationFifty years after the American Revolution, the yeoman farmers who made up a large part of the new country's voters faced a crisis. The very soil of American farms seemed to be failing, and agricultural prosperity, upon which the Republic was founded, was threatened. Steven Stoll's passionate and brilliantly argued book explores the tempestuous debates that erupted between "improvers," who believed in practi...

High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present-day high-capacity machinery caused that the farmers lost the immediate and close contact ...

International concern in scientific, industrial, and governmental communities of xenobiotics in foods and in both abiotic and biotic environments over traces has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in ...

Fifteen years have passed since a small group of researchers at the Czech Geo logical Survey boldly convened a conference called GEOMON, Geochemical Monitoring in Representative Basins, held in Prague in 1987. The focus of the original GEOMON conference was rather narrow - monitoring of element pools and fluxes on a small catchment scale. Signaling a desire to broaden the focus to a more biogeochemical orientation, the 1993 meeting, also in Prague, was renamed BIOGEOMON. Tofoster wider int...

This book presents a beautifully illustrated overview of the most prominent landscapes of South Africa and the distinctive landforms associated with them. It describes the processes, origins and the environmental significance of those landscapes, including their relationships to human activity of the past and present. The sites described in this book include, amongst others, the Blyde River Canyon, Augrabies Falls, Kruger National Park, Kalahari desert landscapes, the Great Escarpment, Ste...

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from scie...

In view of the grave consequences of soil degradation on ecosystem functions, food security, biodiversity and human health, this book covers the extent, causes, processes and impacts of global soil degradation, and processes for improvement of degraded soils. Soil conservation measures, including soil amendments, decompaction, mulching, cover cropping, crop rotation, green manuring, contour farming, strip cropping, alley cropping, surface roughening, windbreaks, terracing, sloping agricult...
