This textbook is aimed at the majority of students, who need toquickly acquire a concise overview of soil science. Many currentsoil science textbooks still cater for a traditional student marketwhere students embark on three years study in a narrow discipline.The growth in modular degree schemes has meant that soil science isnow often taught as self-standing unit as part of broad baseddegree program. Students pursuing this type of course areincreasingly reluctant to purchase expensive textbooks that are toodetailed and often assume a scientific background. For those optingto specialise in soil science there are a variety of good textbooksto choose from. This short informative guide, will be particularlyuseful for students who do not possess a traditional scientificbackground, such as those studying geography, environment science,ecology and agriculture. Only textbook to cater for introductory courses in soilscience. Provides an affordable concise overview of soil science. Learning exercises and chapter summaries enhanceusability.

Scientists play a vital role in the effort to understand the environment and develop new, renewable sources of energy. They are able to identify environmental problems, search for viable solutions, and gauge the effectiveness of these solutions in a wide variety of green fields. They also advise government officials, businesses, and other people and organizations about various environmental issues and concerns. The need for scientific expertise in all aspects of conservation and environmental work suggests that demand for these professionals will be strong in the coming years. Science profiles 15 green careers in this highly sought-after field. Career profiles include: Biochemists Biologists Botanists Chemists Climatologists Ecologists Geologists Meteorologists Oceanographers Soil scientists Wetland scientists Wildlife scientists and more.

The authoritative guide to understanding and managing the ecological impacts of recreational activities in wildlands This third edition provides an updated and thorough examination of the ecological impacts of recreational use on wildlands and the best management practices to employ in places where recreation and preservation of natural conditions are both important - and often conflicting - objectives. Covering the latest research, this edition provides detailed information about the environmental changes that result from recreational use. It describes spatial patterns of impact and trends over time, then explores the factors that determine magnitude of impact, including amount of use, type and behavior of use, and environmental durability. Numerous examples, drawn from parks and recreation areas around the world, give readers insight into why certain areas are more heavily damaged than others, and demonstrate the techniques available to mitigate damage. The book incorporates both the first-hand experience of the authors and an exhaustive review of the world’s literature on the subject. Boxes provide quick access to important material, and further resources are referenced in an extensive bibliography. Essential reading for all park and protected area management professionals, this book is also a useful textbook for upper division undergraduate and graduate students on recreation ecology and recreation management courses.

It’s an astonishing fact that capturing all the energy in just one hour’s worth of sunlight would enable us to meet the planet’s food and energy needs for an entire year. The Solar Revolution tells the story of how scientists are working to reconnect us to the ‘solar economy’, harnessing the power of the sun to provide sustainable food and energy for a global population of 10 billion people: an achievement that would end our dependence on ‘fossilised sunshine’ in the form of coal, oil and gas and remake our connection with the soil that grows our food. Steve McKevitt and Tony Ryan describe the human race’s complex relationship with the sun and take us back through history to see how our world became the place it is today – chemically, geologically, ecologically, climatically and economically – before moving on to the cutting-edge science and technology that will enable us to live happily in a sustainable future.

This third volume in the SAGE Series on Green Society lays out the contours of the field of agri-food studies. It draws on scholars working in the fields of political ecology, rural sociology, geography, and environmental studies to paint a picture of the past, present, and future of agriculture and food. It provides readers with a basic understanding of the institutions, practices, and concepts to identify what is and is not a "green" food. Because food is so intimately connected to our daily lives, the food system offers perhaps the most promise to make change in a sustainable direction. This volume addresses what a sustainable and green food system might look like, what policies would help realize it, and what kinds of tradeoffs we face in deciding which paths to choose. Green Food: An A-to-Z Guide provides people interested in food and agricultural systems the basic analytical and conceptual ideas that explain why our food system looks the way it does, and what can be done to change it for the better. Roughly 150 entries discuss how to address issues related to a green food system, and vivid photos, searchable hyperlinks, numerous cross references, an extensive resource guide, and a clear, accessible writing style make the Green Society volumes ideal for classroom use.

This book discusses the association that exists between plants and their most important dietary component, nitrogen. The author combines ecological, physiological and biochemical approaches to provide the reader with an overall view of nitrogen in the biosphere and a specific view of nitrogen processing in plants. The processes which make up the nitrogen cycle, including mineralization, immobilization by microbes and nitrification, are discussed and the losses and gains of combined nitrogen from and to the cycle. The part which plants play in this cycling, by their processing of inorganic nitrogen into compounds which are required by plants and animals alike, and the chemistry and production of those compounds, is also covered. Transport of nitrogen compounds within the plant, and the fate of these compounds, is discussed. The final chapter considers the part which humans play in the cycling of nitrogen, with special reference to the nitrogen fertilizers used in agriculture.
