Soil in the Environment is key for every course in soil science, earth science, and environmental disciplines. This textbook engages students to critically look at soil as the central link in the function and creation of the terrestrial environment. For the first time, Dr. Hillel brilliantly discusses soils as a natural body that is engaged in dynamic interaction with the atmosphere above and the strata below that influences the planet's climate and hydrological cycle, and serves as the primary habitat for a versatile community of living organisms. The book offers a larger perspective of soil’s impact on the environment by organizing chapters among three main processes: Physical, Chemical, and Biology. It is organized in a student-friendly format with examples, discussion boxes, and key definitions in every chapter. The book provides students of geology, physical science, and environmental studies with fundamental information and tools for meeting the natural resource challenges of the 21st century, while providing students of soil science and ecology with the understanding of physical and biological interactions necessary for sustainability. First textbook to unite soil science and the environment beyond what is traditionally taught Incorporates current knowledge of such hot topics as climate change, pollution control, human expropriation of natural resources, and the prospects for harmonious and sustainable development Organized in a student-friendly format with examples, discussion boxes, and key definitions in every chapter Full color throughout

Nudge – so heißt die Formel, mit der man andere dazu bewegt, die richtigen Entscheidungen zu treffen. Denn Menschen verhalten sich von Natur aus nicht rational. Nur mit einer Portion List können sie dazu gebracht werden, vernünftig zu handeln. Aber wie schafft man das, ohne sie zu bevormunden? Wie erreicht man zum Beispiel, dass sie sich um ihre Altervorsorge kümmern, umweltbewusst leben oder sich gesund ernähren? Darauf gibt Nudge die Antwort. Das Konzept hat bereits viele Entscheidungsträger überzeugt, darunter US-Präsident Barack Obama. Anschaulich und unterhaltsam präsentieren der Wirtschaftsnobelpreisträger Richard Thaler und Cass Sunstein einen neuen Ansatz der Verhaltensökonomie, der schon heute das Denken und Handeln in Politik und Wirtschaft prägt.

With the use of high-level soil management technology, Africa could feed several billion people, yet food production has generally stagnated since the 1960s. No matter how powerful the seed technology, the seedling emerging from it can flourish only in a healthy soil. Accordingly, crop yields in Africa, South Asia, and the Caribbean could be doubled or tripled through adoption of technologies based on laws of sustainable soil management. Principles of Sustainable Soil Management in Agroecosystems describes the application of these laws to enhance ecosystem services while restoring degraded soils and promoting sustainable use. With chapters contributed by world-class soil scientists, ecologists, and social scientists, this book outlines critical changes in management of agricultural soils necessary to achieve food security and meet the food demands of the present and projected future population. These changes include conversion to no-till and conservation agriculture; adoption of strategies of integrated nutrient management, water harvesting, and use of drip sub-irrigation; complex cropping/farming systems such as cover cropping and agroforestry; and use of nano-enhanced fertilizers. The book is based on the premise that it is not possible to extract more from a soil than what is put into it without degrading its quality. The strategy is to replace what is removed, respond wisely to what is changed, and be pro-active to what may happen because of natural and anthropogenic perturbations. The chapters, which exemplify these ideas, cover a range of topics including organic farming, soil fertility, crop-symbiotic soil microbiota, human-driven soil degradation, soil degradation and restoration, carbon sink capacity of soils, soil renewal and sustainability, and the marginality principle.

Principles of Soil and Plant Water Relations, 2e describes the principles of water relations within soils, followed by the uptake of water and its subsequent movement throughout and from the plant body. This is presented as a progressive series of physical and biological interrelations, even though each topic is treated in detail on its own. The book also describes equipment used to measure water in the soil-plant-atmosphere system. At the end of each chapter is a biography of a scientist whose principles are discussed in the chapter. In addition to new information on the concept of celestial time, this new edition also includes new chapters on methods to determine sap flow in plants dual-probe heat-pulse technique to monitor water in the root zone. Provides the necessary understanding to address advancing problems in water availability for meeting ecological requirements at local, regional and global scales Covers plant anatomy: an essential component to understanding soil and plant water relations

Nearly two billion people depend on hundreds of millions of smallholder farmers for food security. Yet, these farmers’ lives also hang in the balance due to their extreme vulnerability to the risks of soil degradation and depletion, soil exhaustion, climate change, and numerous biotic and abiotic stresses. Soil Management of Smallholder Agriculture explores the potential smallholder agriculture hold for advancing global food security and outlines the challenges to achieving this goal. The book addresses the challenges and opportunities that resource-poor and small landholders face and provides recommended management practices to alleviate soil-related constraints, and increase and sustain crop yield and production. It discusses the cultural, economic, social, and technological aspects of sustainable soil management for smallholder farmers. It then examines soil-related and institutional constraints, principles of sustainable agriculture, soil quality improvement, nutrient and soil fertility management, soil carbon sequestration, soil security, efficient use of resources, and agronomic production. Edited by experts, the book makes the case for the adoption of proven technologies of sustainable intensification, producing more from less, both for advancing agronomic production and adapting to changing climate. It outlines a strategy that will usher in a soil-based Green Revolution by increasing the use efficiency of energy-based inputs such as fertilizers, pesticides, and irrigation to restore soil quality, and sequestering carbon in the terrestrial ecosystems. This strategy helps small farms narrow the gap between the actual and attainable crop yield.

Der Entschluß, ein Buch über den Ursprung (bzw. die Ursprünge) des - bens zu verfassen, setzt voraus, daß man von diesem wissenschaftlichen „großen Problem“ noch immer fasziniert ist, wenn auch die erste intensive Beschäftigung mit dieser Thematik mehr als drei Jahrzehnte zurückliegt. Experimentelle Arbeiten über Protein-Modellsubstanzen unter den si- lierten Bedingungen der Urerde führten zur Entstehung eines der ersten deutschsprachigen Bücher über „Chemische und Molekulare Evolution“, das ich mit Klaus Dose (Mainz), von dem auch die Initiative ausging, v- faßte. Die enorme Erweiterung und Differenzierung dieses Forschungsgebietes führte in den letzten Jahren zur Gründung eines neuen, interdisziplinären Wissenschaftszweiges, der „Exo-/Astrobiologie“. Sie verfolgt das we- gespannte, ehrgeizige Ziel, das Phänomen „Leben“ im gesamten Kosmos zu erforschen. In den folgenden Kapiteln wird ein Überblick über die vielfältigen - mühungen von Wissenschaftlern gegeben, Antworten auf die Frage nach dem „Woher“ des Lebens zu finden. Dabei ist über Erfolge, aber auch Mißerfolge sowie über Diskussionen und gelegentlich harte Kontroversen zu berichten. Es soll aber auch deutlich dargestellt werden, wie viele of- ne Fragen und ungeklärte Rätsel noch auf eine Antwort warten. Es sind - ren mehr, als gern eingestanden wird! – Die Fülle an wissenschaftlichen Publikationen macht es leider unmöglich, über alle Bereiche dieses int- disziplinär ausgerichteten Teilgebietes der Naturwissenschaften mit gl- cher Ausführlichkeit zu berichten.

Was wäre, wenn wir Menschen von einem Tag auf den anderen verschwinden würden? Zum Beispiel morgen. Ein ungeheures Gedankenexperiment! Alan Weisman entwirft das Szenario einer unbevölkerten Erde – gestützt auf das Wissen von Biologen, Geologen, Physikern, Architekten und Ingenieuren und mit atemberaubender Phantasie. Schritt für Schritt vollzieht Weisman nach, wie die Natur unseren Planeten zurückerobert, und führt dem Leser dabei zweierlei vor Augen: was der Mensch in Jahrtausenden zu schaffen vermochte und über welch unerhörte Macht die Natur verfügt.
