Global agriculture is now at the crossroads. The Green Revolution of the last century is losing momentum. Rates of growth in food production are now declining, with land and water resources becoming scarcer, while world population continues to grow. We need to continue to identify and share the knowledge that will support successful and sustainable

Agriculture in the 21st century will need considerable modification to remain both productive and sustainable. Greater production is needed to meet the needs of our still-growing populations and to combat hunger and poverty. Declines in soil health and the pollution of water sources are making many of our production systems less tenable. These adverse trends are exacerbated more and more by the impacts of climate change. There are, fortunately, alternative methods available for agricultural practice that can countervail these constraints. Biological Approaches to Regenerative Soil Systems brings together the work of both researchers and practitioners to map out better approaches to contemporary agriculture that draw upon both old and new knowledge. It presents the science that underlies more biologically driven strategies as well as contemporary innovative experiences in diverse parts of the world. Both accepted research and these varied experiences encourage confidence that these approaches, not relying primarily on the introduction of new varieties and on exogenous inputs, can succeed. This book updates and revises a preceding volume Biological Approaches to Sustainable Soil Systems published by CRC Press in 2006. So much has been learned and done on this subject in the past decade and a half that a second edition was warranted. For instance, the first edition was published, knowledge about plant-soil microbiomes, which are a frequent focus in this book, has mushroomed. Because sustainability is a broad term and an end-state, the editors preferred to assemble expertise regarding regenerative agriculture, which is concerned with the means for achieving sustainability. The concept of regenerative soil systems, entities that are more complex and multifaceted than "soil" alone, also incorporates a concern with having more resilient agricultural systems, ones that are better able to cope with the multiple stresses of climate change that are foreseen for the decades ahead. The book’s chapters representing a wide range of disciplines were contributed by 84 scientists and practitioners from 20 countries. Although they come from persons with in-depth knowledge of their respective fields, the chapters are written to be accessible to readers who are not trained in the specialized subjects. Taken together, the chapters provide students, researchers, practitioners, planners, and policy makers with a comprehensive understanding of both the science and the steps needed to regenerate and sustain soil systems around the world for the long-term benefit of humankind and the environment.

Poor land management has degraded vast amounts of land, reduced our ability to produce enough food, and is a major threat to rural livelihoods in many developing countries. This book provides a thorough analysis of the multifaceted impacts of land use on soils. Abundantly illustrated with full-color images, it brings together renowned academics and policy experts to analyze the patterns, driving factors and proximate causes, and the socioeconomic impacts of soil degradation.

Our capacity to maintain world food production depends heavily on the thin layer of soil covering the Earth's surface. The health of this soil determines whether crops can grow successfully, whether a farm business is profitable and whether an enterprise is sustainable in the long term. Farmers are generally aware of the physical and chemical factors that limit the productivity of their soils but often do not recognise that soil microbes and the soil fauna play a major role in achieving healthy soils and healthy crops. Soil Health, Soil Biology, Soilborne Diseases and Sustainable Agriculture provides readily understandable information about the bacteria, fungi, nematodes and other soil organisms that not only harm food crops but also help them take up water and nutrients and protect them from root diseases. Complete with illustrations and practical case studies, it provides growers and their consultants with holistic solutions for building an active and diverse soil biological community capable of improving soil structure, enhancing plant nutrient uptake and suppressing root pests and pathogens. The book is written by scientists with many years' experience developing sustainable crop production practices in the grains, vegetable, sugarcane, grazing and horticultural industries. This book will be useful for: growers, consultants, agronomists and soil chemists, extension personnel working in the grains, livestock, sugarcane and horticultural industries, professionals running courses in soil health/biological farming, and students taking university courses in soil science, ecology, microbiology, plant pathology and other biological sciences.

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.

The root is an organ that generally grows into the soil in developed plants that have adapted to terrestrial life but rarely is found above the ground. The roots have channels to transport nutrients and water to the stem and leaves. Studies on roots will provide opportunities to develop food security and environmental sustainability. This book explains root-soil interactions, ethnobotanical use of roots, secondary metabolite production, and soil resource acquisition from agricultural and ecological perspectives.

'Jules Pretty brings together the most comprehensive and carefully selected collection of writings available about sustainable agriculture. Together with an excellent overview chapter, the collected works provide the best available source for an enlightened analysis and debate about sustainability in agriculture. The four volumes will serve both as an excellent reader for students and a unique reference for all with an interest in the pursuit of sustainabiity in the food system' Professor Per Pinstrup-Andersen, Cornell University, former Chair of CGIAR Science Council and World Food Prize Laureate, 2001 'This is the single most comprehensive overview of sustainable agriculture, from ancient beginnings to the most topical modern issues. Jules Pretty has assembled a marvellous collection of the most seminal papers that are driving sustainable agriculture in all parts of the world.' Jeffrey A. McNeely, Chief Scientist, IUCN-The World Conservation Union 'Showing that, after all, humans can learn from experience, Jules Pretty has woven together the best of the old with the best of what is new and visionary. He gives us a solid, knowledge-based foundation for a badly needed new paradigm - that of an agriculture which sustains all life into the longer term. The impressive list of contributors ensures that all relevant areas have been competently assessed... A unique reference work for teachers, students and practitioners.' Hans R. Herren, World Food Prize Laureate, 1995 'An ambitious and deeply insightful series that unites the great minds not just of the agricultural, nutrition and environmental sciences, but also history, culture, economics, technology, learning and communications, policy, regulatory and institutional approaches. It will be a major reference work for all interested in the future of humanity and sustainable food and agricultural systems.' Parviz Koohafkan, Director, Environment, Climate Change and Bioenergy Division, FAO, Italy 'This work presents a body of knowledge that has come of age. It takes into account not only the science but also human behaviour, institutions and politics. It will be an invaluable support for practices that are rapidly gaining significance.' Professor Neils R�ling, formerly of Wageningen University, The Netherlands This 4-volume set, edited by the world's leading expert on agricultural sustainability, brings together and interprets the most influential, important and time-tested international scholarship across the fields of agriculture and food production with a set overview and individual volume introductions that make sense of this diverse and complex field. Volume I covers the history of agriculture from its ancient origins through successive technological and institutional revolutions to the present. Volume II examines the relationship between agriculture and the environment including agricultural contamination, greenhouse gases and climate change, environmental improvements and sustainability, integrated farming, eco-agriculture and agro-ecology, landscape restoration and environmental goods and services. Volume III provides full coverage of the modern industrialized global food system, corporate control, poverty, hunger and international successes, failures and challenges, diet and health, consumer behaviour and local alternatives to industrialization. Volume IV addresses how we think about land and our relationship to it, governance and stewardship of the rural commons, systems thinking, ecological literacy, social connections and a sustainable rural life, supportive and perverse agricultural subsidies and policies that shape food poverty and sustain agriculture into the future.
