This textbook is aimed at the majority of students, who need to quickly acquire a concise overview of soil science. Many current soil science textbooks still cater for a traditional student market where students embark on three years study in a narrow discipline. The growth in modular degree schemes has meant that soil science is now often taught as self-standing unit as part of broad based degree program. Students pursuing this type of course are increasingly reluctant to purchase expensive textbooks that are too detailed and often assume a scientific background. For those opting to specialise in soil science there are a variety of good textbooks to choose from. This short informative guide, will be particularly useful for students who do not possess a traditional scientific background, such as those studying geography, environment science, ecology and agriculture. Only textbook to cater for introductory courses in soil science. Provides an affordable concise overview of soil science. Learning exercises and chapter summaries enhance usability. Annotated suggestions for further reading. Based on proven and successful modular course structure. Emphasis on readability and interactive learning. No scientific background assumed.

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.

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.

Böden gehören zu den wichtigsten Lebensgrundlagen der Menschheit. Sie unterscheiden sich in den verschiedenen Regionen der Erde außerordentlich stark. Dieser Bildatlas beschreibt und illustriert die Böden der Welt im Zusammenhang mit ihren Naturräumen. Grundlage ist die internationale Bodenklassifikation WRB (World Reference Base for Soil Resources) in der Neuauflage von 2006. Darin sind zahlreiche Begriffe neu bzw. schärfer definiert. Mit den Technosolen und Stagnosolen fanden zwei neue Referenzbodengruppen Aufnahme. Auch die weitere Untergliederung der Böden mit Hilfe von Qualifiern wurde deutlich verändert und erweitert. Diese zahlreichen Änderungen in der WRB von 2006 sind in die 2. Auflage des Buches eingegangen. Das Buch ist nach Ökozonen gegliedert. Für jede Ökozone werden Lage, Klima und Vegetation mit den sich daraus ergebenden bodenbildenden Faktoren beschrieben. Darauf folgen umfassende Informationen über deren repräsentative Böden: Definition der Böden, diagnostische Horizonte, Eigenschaften und Materialien, physikalische, chemische und biologische Merkmale, Vorkommen und Verbreitung, Nutzung und Gefährdung, Prozesse der Bodenbildung. Zahlreiche Diagramme zur Verbreitung der Böden, zu Profilmerkmalen und bodenbildenden Prozessen sowie viele neue Farbfotos von Bodenprofilen und -landschaften machen den Bildatlas zu einem ausgezeichneten Referenzwerk. Studierende und Lehrende sowie Entscheidungsträger werden zudem mit grundlegenden Erkenntnissen der Bodenkunde, des Bodenschutzes und der Bodenfruchtbarkeit vertraut gemacht. Bevölkerungswachstum und Bodendegradation in tropischen Gebieten, deren Böden von Natur aus nur eingeschränkt fruchtbar sind, machen die Ernährungssicherung in besonderem Maße zu einer Aufgabe der Bodenkunde.

»Ich bin einer von ungezählten Millionen, die durch Nelson Mandelas Leben inspiriert wurden.« Barack Obama Eine fast drei Jahrzehnte währende Gefängnishaft ließ Nelson Mandela zum Mythos der schwarzen Befreiungsbewegung werden. Kaum ein anderer Politiker unserer Zeit symbolisiert heute in solchem Maße die Friedenshoffnungen der Menschheit und den Gedanken der Aussöhnung aller Rassen wie der ehemalige südafrikanische Präsident und Friedensnobelpreisträger. Auch nach seinem Tod finden seine ungebrochene Charakterstärke und Menschenfreundlichkeit die Bewunderung aller friedenswilligen Menschen auf der Welt. Mandelas Lebensgeschichte ist über die politische Bedeutung hinaus ein spannend zu lesendes, kenntnis- und faktenreiches Dokument menschlicher Entwicklung unter Bedingungen und Fährnissen, vor denen die meisten Menschen innerlich wie äußerlich kapituliert haben dürften.
