This introductory book to the six volume series includes an introduction defining the critical zone for mankind that extends from tree canopy and the lower atmosphere to water table and unweathered rock. Soils play a crucial role through the functions and the services that they provide to mankind. The spatial and temporal variability of soils is represented by information systems whose importance, recent evolutions and increasingly performing applications in France and in the world must be underlined. The soil functions, discussed in this book, focus on the regulation of the water cycle, biophysicochemical cycles and the habitat role of biodiversity. The main services presented are those related to the provision of agricultural, fodder and forest products, energy, as well as materials and the role of soil as infrastructure support. They also include the different cultural dimensions of soils, their representations being often linked to myths and rites, as well as their values of environmental and archaeological records. Finally, the issue is raised of an off-ground world.

This book invites the reader to look differently at two seemingly mundane resources: soil and water. Water possesses extraordinary properties which form the foundations of life itself. Without water, there would be no life, and without soils, no terrestrial life. The interaction between soils and water is therefore fundamental to the habitability of Earth’s land surface. Through in-depth analyses and experimentation, Soils as a Key Component of the Critical Zone 3 explores the circulation of water in soils. Through its properties, soil directs the path of water, leading it to wet soils or not, be absorbed by plants, infiltrate or runoff, concentrate in certain areas or flood. The potentially catastrophic consequences of such floods are often due to the absence or insufficiency of prevention measures. This book thus shows the ways in which the relationship between water, life and soils is much more than a simple series of interactions or phenomena at interfaces and in fact constitutes a system with definite properties.

One third of the world's soils have already been degraded. The burden on the land continues to grow under the combined pressures of demography, urbanization, artificialization and mining, and there are increased demands on agricultural land: changing dietary preferences, land speculation, as well as new demands for agroenergy, fiber, green chemistry, and more. Resulting issues such as soil crusting, water and wind erosion, soil salinization and soil acidity therefore constitute a major threat. The authors of this book present the main processes and factors of soil degradation, different ways to prevent it and methods of rehabilitation. The book also deals with the origin and processes of metallic and organic soil pollution as well as methods of phytoremediation and restoration. It is one of the few books to explore the issue of soil artificialization and urban soil management and to highlight how agricultural and urban waste can be used to amend and fertilize cultivated soils.

The second edition of The Chemistry of Soils, published in 2008, has been used as a main text in soil-science courses across the world, and the book is widely cited as a reference for researchers in geoscience, agriculture, and ecology. The book introduces soil into its context within geoscience and chemistry, addresses the effects of global climate change on soil, and provides insight into the chemical behavior of pollutants in soils. Since 2008, the field of soil science has developed in three key ways that Sposito addresses in this third edition. For one, research related to the Critical Zone (the material extending downward from vegetation canopy to groundwater) has undergone widespread reorganization as it becomes better understood as a key resource to human life. Secondly, scientists have greatly increased their understanding of how organic matter in soil functions in chemical reactions. Finally, the study of microorganisms as they relate to soil science has significantly expanded. The new edition is still be comprised of twelve chapters, introducing students to the principal components of soil, discussing a wide range of chemical reactions, and surveying important human applications. The chapters also contain completely revised annotated reading lists and problem sets.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

2 nung der durch Änderungen in der Belastung und in den Entwässe rungsbedingungen verursachten Wirkungen meist nur sehr gering sind. Diese Feststellung gilt im besonderen Maße für alle jene Auf gaben, die sich mit der Wirkung des strömenden Wasser befassen, weil hier untergeordnete Abweichungen in der Schichtung, die durch Probebohrungen nicht aufgeschlossen werden, von großem Einfluß sein können. Aus diesem Grunde unterscheidet sich die Anwendung der theoretischen Bodenmechanik auf den Erd- und Grundbau ganz wesentlich von der Anwendung der technischen Mechanik auf den Stahl-, Holz- und Massivbau. Die elastischen Größen der Baustoffe Stahl oder Stahlbeton sind nur wenig veränderlich, und die Gesetze der angewandten Mechanik können für die praktische Anwendung ohne Einschränkung übertragen werden. Demgegenüber stellen die theoretischen Untersuchungen in der Bodenmechanik nur Arbeits hypothesen dar, weil unsere Kenntnisse über die mittleren physikalischen Eigenschaften des Untergrundes und über den Verlauf der einzelnen Schichtgrenzen stets unvollkommen und sogar oft äußerst unzuläng lich sind. Vom praktischen Standpunkt aus gesehen, sind die in der Bodenmechanik entwickelten Arbeitshypothesen jedoch ebenso an wendbar wie die theoretische Festigkeitslehre auf andere Zweige des Bauingenieurwesens. Wenn der Ingenieur sich der in den grundlegen den Annahmen enthaltenen Unsicherheiten bewußt ist, dann ist er auch imstande, die Art und die Bedeutung der Unterschiede zu er kennen, die zwischen der Wirklichkeit und seiner Vorstellung über die Bodenverhältnisse bestehen.

Das Standardwerk über vernünftige Ernährung Der Mensch gehört von der Konsititution seiner Verdauungsorgane her zu den Omnivoren, den Allesfressern. Das war in der Evolution sicherlich nützlich. Doch das heutige Überangebot von Nahrungsmitteln in Supermärkten und Schnellrestaurants bringt nicht nur ihn selbst körperlich an den Rand des Abgrunds, sondern ruiniert auch noch seinen Lebensraum und sein soziales Umfeld. Mit Biss und investigativer Recherche sieht sich Pollan um, wie unsere Nahrungsmittel hergestellt und verarbeitet werden, vom Maisfeld über Cheeseburger mit Pommes bis zum Öko-Menü. Er öffnet uns die Augen für unser gestörtes Essverhalten und für den Weg zurück zu Einfachheit und Genuss.

The world's water resources are coming under increasing stress, a stress that will become critical globally sometime during the next century. This is due to the rapidly rising population demanding more and more water and an increasing level of affluence. The book discusses the background to this issue and the measures to be taken over the next 20-30 years to overcome some of the difficulties that can be foreseen, and the means of avoiding others, such as the hazard of floods. It looks at the water resource and its assessment and management in an integrated fashion. It deals with the requirements of agriculture and of rural and urban societies and to a lesser extent with those of industry and power, against the background of the needs of the natural environment. It presents a number of ways and means of improving the management of national and international affairs involving fresh water. It highlights the importance of fresh water as a major issue for the environment and for development.
