Six Chemicals That Changed Agriculture is a scientific look at how the chemicals used in today's food production were developed, evaluated, and came to be in wide-spread use. From fertilizers to pest management, antibiotics to DNA, chemicals have transformed the way our food is grown, protected, and processed. Agriculture is the world's most important environment interaction, the essential human activity, and an increasingly controversial activity because of its use and presumed misuse of chemistry. The major characteristics of US agriculture for at least the last six decades have been rising productivity, declining number of mid-size farms, increasing farm size, an increasing percentage of farm production on fewer, large farms, increasing dependence of chemical technology and more developmental research being done by the agricultural chemical industry rather than by independent land-grant universities. Another equally important feature of modern agriculture is wide-spread suspicion of its technology by the public. The book will recount examples of this suspicion related to specific chemicals and present the essence of the suspicion and its results. Offers an historical analysis of the discovery and development some aspects of the chemistry of modern agriculture Addresses the advantages, disadvantages, desirable and undesirable results of the use of each of the chosen chemicals and compares and contrasts the real and frequently assumed problems of their use Provides valuable insights into the history and application of these focused chemicals, enabling readers to apply the lessons to new agricultural chemical developments

A NEW YORK TIMES NOTABLE BOOK OF THE YEAR | SHORT-LISTED FOR THE 2018 LIONEL GELBER PRIZE | NAMED A BEST BOOK OF THE YEAR BY: FINANCIAL TIMES * THE TIMES (LONDON) * AMAZON “Allison is one of the keenest observers of international affairs around.”— JOE BIDEN, former vice president of the United States China and the United States are heading toward a war neither wants. The reason is Thucydides’s Trap: when a rising power threatens to displace a ruling one, violence is the likeliest result. Over the past five hundred years, these conditions have occurred sixteen times; war broke out in twelve. Today, as an unstoppable China approaches an immovable America, and both Xi Jinping and Donald Trump promise to make their countries “great again,” the seventeenth case looks grim. A trade conflict, cyberattack, Korean crisis, or accident at sea could easily spark a major war. In Destined for War, eminent Harvard scholar Graham Allison masterfully blends history and current events to explain the timeless machinery of Thucydides’s Trap—and to explore the painful steps that might prevent disaster today. “[A] must-read book in both Washington and Beijing.”— NIALL FERGUSON, BOSTON GLOBE “[Allison is] a first-class academic with the instincts of a first-rate politician.”— BLOOMBERG NEWS “[Full of] wide-ranging, erudite case studies that span human history . . .

An oft-neglected element supports all life on Earth and holds a key to our future... Across the world, social, political, and economic pressures influence the biogeochemical cycle of phosphorus, the 11th most abundant element of the Earth's crust. Phosphorus is essential to produce our food, but it triggers algal blooms in lakes, rivers, and oceans when it slips through our hands. An understanding of this essential resource and how we have used and misused it over the years is crucial to the sustainability of our well-being on our planet. In this book, world authorities on phosphorus sustainability, Jim Elser and Phil Haygarth explain this element's involvement in biology, human health and nutrition, food production, ecosystem function, and environmental sustainability. Phosphorus chronicles the sustainability challenges phosphorus both poses and solves in various contexts. The book begins with its discovery over 350 years ago, moving to its basic chemistry, and the essential role it plays in all living things on Earth. Chapters go on to explain the rise in the usage of phosphorus in agriculture and how the increase in the mining of rock phosphate in the mid-20th century was essential for the Green Revolution. However, phosphorus emissions from human wastes and detergents triggered widespread algae blooms in the 1960s and 1970s. While such emissions have been brought under better control with wastewater treatment, diffuse emissions from farming continue to cause water quality degradation. The authors explain how these diffuse phosphorus emissions may worsen with climate change. In ten concise chapters, Elser and Haygarth offer engaging explanations of our historical use and abuse of phosphorus, including the phosphorus sustainability movement and new efforts to sustain food benefits of limited rock reserves following the price shock of phosphate rock in 2007-2008. Highlighting new approaches from phosphorus "Systems Innovators," Elser and Haygarth turn toward the emerging set of sustainable phosphorus solutions necessary to achieve a sustainable "phosphoheaven" and avoid "phosphogeddon." The book provides an insider's take on this essential resource and why all of us need to wrestle with the wicked problems this element will cause, illuminate, or eliminate in years to come.

What are the goals of agricultural science? What should the goals of agricultural science be? How do and how should the practitioners of agriculture address complex ethical questions? These questions are explored in this monumental book so that those in agriculture will begin an open dialoge on the ethics of agriculture. Discussion of foundational values, of why we practice agriculture as we do, should become a central, rather than peripheral, part of agricultural practice and education. If agricultural scientists do not venture forth to understand and shape the ethical base of the future, it will be imposed by others. Largely autobiographical, this book covers topics such as scientific truth and myth, what agricultural research should be done, an introduction to ethics, moral confidence in agriculture, the relevance of ethics to agriculture, sustainability, and biotechnology. * Written by an expert who has been engaged in agricultural education and research for over 35 years * Content is easily understandable by non-philosophers * The concepts of scientific truth and myth are contrasted and compared * Chapter sidebars highlight important concepts and can be used to engage students in further discussion * Companion website will accompany the book with further teaching aids and a discussion board

This book addresses herbicides and their use as an important aspect of modern weed management and strives to place them in an ecological framework. Many weed scientists believe agriculture is a continuing struggle with weeds--without good weed control, good and profitable agriculture is impossible. Each agricultural discipline sees itself as central to agriculture's success and continued progress, and weed science is no exception. While not denying the importance of weed management to successful agriculture, this book places it in a larger ecological context. The roles of culture, economics, and politics in weed management are also discussed, enabling scientists and students to understand the larger effects on society. Information on New herbicides included, along with the old herbicides that are important for understanding the history New section on weed resistance to herbicides and genetic engineering New information on invasive plants Expanded chapters on Biological Control, Pesticide Legislation and Regulation, Weed Management Systems, and more Instructor resources can be found at http://textbooks.elsevier.com/web/Login.aspx, and it is password protected.

How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role

WITH A FOREWORD BY WALTER MURCH Gene Phillips blends biography, studio history, and film criticism to complete the most comprehensive work on Coppola ever written. The force behind such popular and critically acclaimed films as Apocalypse Now and the Godfather trilogy, Coppola has imprinted his distinct style on each of his movies and on the landscape of American popular culture. In Godfather, Phillips argues that Coppola has repeatedly bucked the Hollywood "factory system" in an attempt to create distinct films that reflect his own artistic vision -- often to the detriment of his career and finances. Phillips conducted interviews with the director and his colleagues and examined Coppola's production journals and screenplays. Phillips also reviewed rare copies of Coppola's student films, his early excursions into soft-core pornography, and his less celebrated productions such as One from the Heart and Tucker: The Man and His Dream. The result is the definitive assessment of one of Hollywood's most enduring and misunderstood mavericks.

Introduction to Chemicals from Biomass, Second Edition presents an overview of the use of biorenewable resources in the 21st century for the manufacture of chemical products, materials and energy. The book demonstrates that biomass is essentially a rich mixture of chemicals and materials and, as such, has a tremendous potential as feedstock for making a wide range of chemicals and materials with applications in industries from pharmaceuticals to furniture. Completely revised and updated to reflect recent developments, this new edition begins with an introduction to the biorefinery concept, followed by chapters addressing the various types of available biomass feedstocks, including waste, and the different pre-treatment and processing technologies being developed to turn these feedstocks into platform chemicals, polymers, materials and energy. The book concludes with a discussion on the policies and strategies being put in place for delivering the so-called Bioeconomy. Introduction to Chemicals from Biomass is a valuable resource for academics, industrial scientists and policy-makers working in the areas of industrial biotechnology, biorenewables, chemical engineering, fine and bulk chemical production, agriculture technologies, plant science, and energy and power generation. We need to reduce our dependence on fossil resources and increasingly derive all the chemicals we take for granted and use in our daily life from biomass – and we must make sure that we do this using green chemistry and sustainable technologies! For more information on the Wiley Series in Renewable Resources, visit www.wiley.com/go/rrs Topics covered include: • The biorefinery concept • Biomass feedstocks • Pre-treatment technologies • Platform molecules from renewable resources • Polymers from bio-based monomers • Biomaterials • Bio-based energy production Praise for the 1st edition: “Drawing on the expertise of the authors the book involves a degree of plant biology and chemical engineering, which illustrates the multidisciplinary nature of the topic beautifully” - Chemistry World

Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide use--concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agriculture--globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
