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.

This book explores the risks and benefits of crops that are genetically modified for pest resistance, the urgency of establishing an appropriate regulatory framework for these products, and the importance of public understanding of the issues. The committee critically reviews federal policies toward transgenic products, the 1986 coordinated framework among the key federal agencies in the field, and rules proposed by the Environmental Protection Agency for regulation of plant pesticides. This book provides detailed analyses of: * Mechanisms and results of genetic engineering compared to conventional breeding for pest resistance. * Review of scientific issues associated with transgenic pest-protected plants, such as allergenicity, impact on nontarget plants, evolution of the pest species, and other concerns. * Overview of regulatory framework and its use of scientific information with suggestions for improvements.

This new release presents the wealth of information gleaned about nonhuman primates nutrition since the previous edition was published in 1978. With expanded coverage of natural dietary habits, gastrointestinal anatomy and physiology, and the nutrient needs of species that have been difficult to maintain in captivity, it explores the impact on nutrition of physiological and life-stage considerations: infancy, weaning, immune function, obesity, aging, and more. The committee also discusses issues of environmental enrichment such as opportunities for foraging. Based on the world's scientific literature and input from authoritative sources, the book provides best estimates of nutrient requirements. The volume covers requirements for energy: carbohydrates, including the role of dietary fiber; proteins and amino acids; fats and fatty acids; minerals, fat-soluble and water-soluble vitamins; and water. The book also analyzes the composition of important foods and feed ingredients and offers guidelines on feed processing and diet formulation.

Our nation faces daunting challenges to its food and fiber system and to the condition of our natural resources in the coming decades. Rapid increases in world population and the pressure on resources generated by increasing per capita consumption as a result of increasing per capita income challenge the very basis of our standard of living-our food, fiber, and natural-resource base. As the nation faces the challenges, new technologies and new information systems are changing the face of biologic research. The US Department of Agriculture (USDA) has traditionally been the nation's primary public research engine in food, fiber, and natural resources. The National Research Initiative Competitive Grants Program (NRI) is a small part of that USDA research effort, but it accounts for a substantial portion of the nation's merit-based peer-reviewed fundamental research efforts in food, fiber, and natural resources. In 1997, USDA asked the National Research Council Board on Agriculture (now the Board on Agriculture and Natural Resources) to conduct an independent assessment of the NRI program.Specifically, USDA asked the Research Council to: perform a retrospective assessment of the quality and value of research funded by the program; determine whether the science and technology priorities in the major NRI programs are defined appropriately; assess how NRI activities complement other USDA programs, those of other federal agencies, and state programs in the private sector; and recommend the nature and content of changes for the future. This report summarizes the results of the committee's analysis. Chapter 2 summarizes the value of food, fiber, and natural resources-research to the United States, focusing on economic contributions and rates of return of food and fiber research. The committee's analysis of the quality, value, fairness, relevance, and responsiveness of the NRI competitive grants program is presented in chapter 3. Chapter 4 presents the committee's analysis of the role and scope of the NRI, including its scientific objectives, its value in training and education, and its complementarity with other research activities. The committee's analysis of NRI's priority-setting process and its research priorities is given in chapter 5.The committee's analysis of organizational and funding issues is given in chapter 6. Chapter 7 presents the committee's recommendations to improve the effectiveness of the NRI program. Additional supporting materials are found in appendixes A through I.

The rapid expansion of international trade has brought to the fore issues of conflicting national regulations in the area of plant, animal, and human health. These problems include the concern that regulations designed to protect health can also be used for protection of domestic producers against international competition. At a time when progressive tariff reform has opened up markets and facilitated trade, in part responding to consumer demands for access to a wide choice of products and services at reasonable prices, closer scrutiny of regulatory measures has become increasingly important. At the same time, there are clear differences among countries and cultures as to the types of risk citizens are willing to accept. The activities of this conference were based on the premise that risk analyses (i.e., risk assessment, management, and communication) are not exclusively the domain of the biological and natural sciences; the social sciences play a prominent role in describing how people in different contexts perceive and respond to risks.Any effort to manage sanitary and phytosanitary (SPS) issues in international trade must integrate all the sciences to develop practices for risk assessment, management, and communication that recognize international diversity in culture, experience, and institutions. Uniform international standards can help, but no such norms are likely to be acceptable to all countries. Political and administrative structures also differ, causing differences in approaches and outcomes even when basic aims are compatible. Clearly there is considerable room for confusion and mistrust. The issue is how to balance the individual regulatory needs and approaches of countries with the goal of promoting freer trade. This issue arises not only for SPS standards but also in regard to regulations that affect other areas such as environmental quality, working conditions, and the exercise of intellectual property rights. This conference focused on these issues in the specific area of SPS measures. This area includes provisions to protect plant and animal health and life and, more generally, the environment, and regulations that protect humans from foodborne risks.The Society for Risk Analysis defines a risk as the potential for realization of unwanted, adverse consequences to human life, health, property, or the environment; estimation of risk is usually based on the expected value of the conditional probability of the event occurring times the consequence of the event given that it has occurred. The task of this conference and of this report was to elucidate the place of science, culture, politics, and economics in the design and implementation of SPS measures and in their international management. The goal was to explore the critical roles and the limitations of the biological and natural sciences and the social sciences, such as economics, sociology, anthropology, philosophy, and political science in the management of SPS issues and in judging whether particular SPS measures create unacceptable barriers to international trade. The conference's objective also was to consider the elements that would compose a multidisciplinary analytical framework for SPS decision making and needs for future research.

The National Research Council's (NRC) Board on Agriculture and Natural Resources invited professional societies associated with agriculture and ecology to participate in a two-day workshop to explore leadership and a common vision for ecologically based pest management (EBPM). These proceedings describe the challenges of and opportunities for EBPM discussed by participants in the workshop.

Proponents of agricultural biotechnology believe that genetically modified (GM) crops have the potential to provide great ecological benefits, such as reduced pesticide and land use, as well as agricultural benefits. However, given the rapid emergence of commercial GM crops and the likely increase in their use, many groups have raised concerns about the potential unintended, adverse ecological effects of these crops. Some ecological concerns are enhanced development of pest resistance, crosspollination with wild relatives, and reductions in beneficial insects or birds. Ecological Monitoring of Genetically Modified Crops considers the latest in monitoring methods and technologies and to asks--What are the challenges associated with monitoring for ecological effects of GM crops? Is ongoing ecological monitoring of GM crops a useful and informative activity? If so, how should scientifically rigorous monitoring be carried out in the variety of ecological settings in which GM crops are grown?

The U.S. Department of Agriculture (USDA) requested that the Board on Agriculture and Natural Resources of the National Research Council (NRC) convene a panel of experts to examine whether publicly funded agricultural research has influenced the structure of U.S. agriculture and, if so, how. The Committee to Review the Role of Publicly Funded Agricultural Research on the Structure of U.S. Agriculture was asked to assess the role of public-sector agricultural research on changes in the size and numbers of farms, with particular emphasis on the evolution of very-large-scale operations.

Transgenic crops offer the promise of increased agricultural productivity and better quality foods. But they also raise the specter of harmful environmental effects. In this new book, a panel of experts examines: a Similarities and differences between crops developed by conventional and transgenic methods a Potential for commercialized transgenic crops to change both agricultural and nonagricultural landscapes a How well the U.S. government is regulating transgenic crops to avoid any negative effects. Environmental Effects of Transgenic Plants provides a wealth of information about transgenic processes, previous experience with the introduction of novel crops, principles of risk assessment and management, the science behind current regulatory schemes, issues in monitoring transgenic products already on the market, and more. The book discusses public involvementa "and public confidencea "in biotechnology regulation. And it looks to the future, exploring the potential of genetic engineering and the prospects for environmental effects.

Nonindigenous plants and plant pests that find their way to the United States and become invasive can often cause problems. They cost more than $100 billion per year in crop and timber losses plus the expense of herbicides and pesticides. And this figure does not include the costs of invasions in less intensively managed ecosystems such as wetlands. Nonindigenous Plants and Plant Pests examines this growing problem and offers recommendations for enhancing the science base in this field, improving our detection of potential invaders, and refining our ability to predict their impact. The book analyzes the factors that shape an invadera (TM)s progress through four stages: arriving through one of many possible ports of entry, reaching a threshold of survival, thriving through proliferation and geographic spread, and ultimate impact on the organisma (TM)s new environment. The book also reviews approaches to predicting whether a species will become an invader as well as the more complex challenge of predicting and measuring its impact on the environment, a process involving value judgments and risk assessment.This detailed analysis will be of interest to policymakers, plant scientists, agricultural producers, environmentalists, and public agencies concerned with invasive plant and plant pest species.

The science of animal nutrition has made significant advances in the past century. In looking back at the discoveries of the 20th century, we can appreciate the tremendous impact that animal nutrition has had on our lives. From the discovery of vitamins and the sweeping shift in the use of oilseeds to replace animal products as dietary protein sources for animals during the war times of the 1900s-to our integral understanding of nutrients as regulators of gene expression today-animal nutrition has been the cornerstone for scientific advances in many areas. At the milestone of their 70th year of service to the nation, the National Research Council's (NRC) Committee on Animal Nutrition (CAN) sought to gain a better understanding of the magnitude of recent discoveries and directions in animal nutrition for the new century we are embarking upon. With financial support from the NRC, the committee was able to organize and host a symposium that featured scientists from many backgrounds who were asked to share their ideas about the potential of animal nutrition to address current problems and future challenges.

Genetic-based animal biotechnology has produced new food and pharmaceutical products and promises many more advances to benefit humankind. These exciting prospects are accompanied by considerable unease, however, about matters such as safety and ethics. This book identifies science-based and policy-related concerns about animal biotechnologya "key issues that must be resolved before the new breakthroughs can reach their potential. The book includes a short history of the field and provides understandable definitions of terms like cloning. Looking at technologies on the near horizon, the authors discuss what we know and what we fear about their effectsa "the inadvertent release of dangerous microorganisms, the safety of products derived from biotechnology, the impact of genetically engineered animals on their environment. In addition to these concerns, the book explores animal welfare concerns, and our societal and institutional capacity to manage and regulate the technology and its products. This accessible volume will be important to everyone interested in the implications of the use of animal biotechnology.

Forests are major components of the earth's natural resources and they are increasingly critical to the welfare of the U.S. economy, environment, and population. Desires to improve forest management and productivity, preserve biodiversity, maintain ecologic integrity, and provide societal services, such as recreation and tourism, necessitate a strong forestry-research base. Given the clear importance of forestry research in sustaining forests for the future, the U.S. Department of Agriculture (USDA) Forest Service asked the Board on Agriculture and Natural Resources of the National Academies to undertake a study of the nation's capacity in forestry research. The Committee on National Capacity in Forestry Research was appointed to carry out the study, which was conducted to review the current expertise and status of forestry research and to examine the approaches of natural resources education and forestry-research organizations to meet future needs.

This is an interim report of the ad hoc Committee on Air Emissions from Animal Feeding Operations of the National Research Council's Committee on Animal Nutrition. A final report is expected to be issued by the end of 2002. The interim report is intended to provide the committee's findings to date on assessment of the scientific issues involved in estimating air emissions from individual animal feeding operations (swine, beef, dairy, and poultry) as related to current animal production systems and practices in the United States. The committee's final report will include an additional assessment within eight broad categories: industry size and structure, emission measurement methodology, mitigation technology and best management plans, short- and long-term research priorities, alternative approaches for estimating emissions, human health and environmental impacts, economic analyses, and other potential air emissions of concern. This interim report focuses on identifying the scientific criteria needed to ensure that estimates of air emission rates are accurate, the basis for these criteria in the scientific literature, and uncertainties associated with them.It also includes an assessment of the emission-estimating approaches in a recent U.S. Environmental Protection Agency (EPA) report Air Emissions from Animal Feeding Operations. Finally, it identifies economic criteria needed to assess emission mitigation techniques and best management practices.

This report is a congressionally mandated review of the US Department of Agriculturea (TM)s Research, Education, and Economics (REE) mission area, the main engine of publicly funded agricultural research in the United States. A changing social and scientific context of agriculture requires a new vision of agricultural research -- one that will support agriculture as a positive economic, social, and environmental force. REE is uniquely positioned to advance new research frontiers in environment, public health, and rural communities. The report recommends that REE be more anticipatory and strategic in its use of limited resources and guide and champion new directions in research.

The National Plant Genome Initiative was launched in 1998 as a long-term project to explore DNA structure and function in plants so that useful properties of plants can be understood, improved, and ultimately harnessed to address national needs, including agriculture, nutrition, energy and waste reduction. Experts in the community were asked to consider how to build on current accomplishments in order to address major questions in plant biology and to make recommendations for objectives for the next five-year phase of the Initiative.

Public confidence in the security of the US food and fiber system has been sustained by the quality, variety, abundance, and affordability of agricultural products in the United States. Although the system in place to defend against unintentional threats to agriculture has weaknesses and needs, the demonstrated ability of the system to resolve, accommodate, or manage critical food safety problems, temporary shortages of some commodities, plant and animal infestations and diseases, and natural disasters indicates that, in general, such confidence has been warranted. However, over the last several years, there has been recognition of the possibility and consequences of intentional threats directed at US agriculture. Such attacks could come from foreign or domestic terrorists and use biological, chemical, or radiological agents. They could be directed at the pre harvest (live plant and live animal) or post harvest (processing and distribution) stages of food and fiber production.Countering Agricultural Bioterrorism asseses the vulnerability of US agriculture to intentional threats and provides recommendations needed to strengthen and adapt the US system for defense against biological threats to agriculture.

Johne's Disease is a chronic, progressive intestinal disease caused by infection with Mycobacterium avium subspecies paratuberculosis (Map) that affects primarily ruminant animals. In recent decades there has been growing concern over the lack of effective control of this disease and questions have arisen regarding the possibility that Map infection could be a cause of some cases of Crohn's disease in humans. This report presents a broad outline of the steps that should be taken to control Johne's disease, reduce the spread of Map, and minimize effects of the disease in animals. The report also describes the weaknesses of our current research agenda and provides recommendations for a new research strategy to resolve the question of whether there is a link between Johne's and Crohn's diseases.

Updating recommendations last made by the National Research Council in the mid-1980s, this report provides nutrient recommendations based on physical activity and stage in life, major factors that influence nutrient needs. It looks at how nutrients are metabolized in the bodies of dogs and cats, indications of nutrient deficiency, and diseases related to poor nutrition. The report provides a valuable resource for industry professionals formulating diets, scientists setting research agendas, government officials developing regulations for pet food labeling, and as a university textbook for dog and cat nutrition. It can also guide pet owners feeding decisions for their pets with information on specific nutrient needs, characteristics of different types of pet foods, and factors to consider when feeding cats and dogs.

Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.

Food safety regulators face a daunting task: crafting food safety performance standards and systems that continue in the tradition of using the best available science to protect the health of the American public, while working within an increasingly antiquated and fragmented regulatory framework. Current food safety standards have been set over a period of years and under diverse circumstances, based on a host of scientific, legal, and practical constraints. Scientific Criteria to Ensure Safe Food lays the groundwork for creating new regulations that are consistent, reliable, and ensure the best protection for the health of American consumers. This book addresses the biggest concerns in food safetya "including microbial disease surveillance plans, tools for establishing food safety criteria, and issues specific to meat, dairy, poultry, seafood, and produce. It provides a candid analysis of the problems with the current system, and outlines the major components of the task at hand: creating workable, streamlined food safety standards and practices.

Centuries of scientific advances in agriculture have increased the quantity, quality, and variety of our food supply. Food in the United States is abundant and affordable, incomes are at record levels, nutrition and health knowledge is at an all-time high. Yet many Americans are not eating a proper diet. The result is an obesity epidemic that contributes to rising healthcare costs from increased rates of heart disease, stroke, diabetes, and several cancers. Whether we see food as medicine or as the cause of disease, medical and agricultural research have the potential to come together in innovative ways to help consumers and producers understand and face the challenges of following a healthful diet. More than 100 leaders in agriculture, health research, education policy, and industry convened at the National Academies in June 2003 to share their opinions on what would be a more efficient and effective system for conducting food and health research. Some of their thoughts follow.Participants concluded that no one organization or agency can solve food-related health issues alone-- the nation needs better mechanisms for bringing together its agriculture and health-care infrastructures to address food-related health problems. Addressing the obesity issue, in particular, will require a multidisciplinary strategy that includes research on foods, consumer knowledge and behavior, and the economics of food- and health-related activities, including food pricing, health-care costs, and agricultural support programs.

Genetically engineered organisms (GEOs) have been under development for more than 20 years while GE crops have been grown commercially during the last decade. During this time, a number of questions have cropped up concerning the potential consequences that certain GEOs might have on natural or managed ecosystems and human health. Interest in developing methods to confine some GEOs and their transgenes to specifically designated release settings has increased and the success of these efforts could facilitate the continued growth and development of this technology. Biological Confinement of Genetically Engineered Organisms examines biological methods that may be used with genetically engineered plants, animals, microbes, and fungi. Bioconfinement methods have been applied successfully to a few non-engineered organisms, but many promising techniques remain in the conceptual and experimental stages of development. This book reviews and evaluates these methods, discusses when and why to consider their use, and assesses how effectively they offer a significant reduction of the risks engineered organisms can present to the environment.Interdisciplinary research to develop new confinement methods could find ways to minimize the potential for unintended effects on human health and the environment. Need for this type of research is clear and successful methods could prove helpful in promoting regulatory approval for commercialization of future genetically engineered organisms.

This interim report assesses issues related to animal management, husbandry, health, and care at the Smithsonian Institution's National Zoological Park. The report finds that there are shortcomings in care and management that are threatening the well-being of the animal collection and identifies the "most pressing" issues that should be addressed.

Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.

Human-induced climate change is an important environmental issue worldwide, as scientific studies increasingly demonstrate that human activities are changing the Eartha (TM)s climate. Even if dramatic reductions in emissions were made today, some human-induced changes are likely to persist beyond the 21st century. The Kyoto Protocol calls for emissions reporting that separates out management-induced changes in greenhouse gases from those changes caused by indirect human effects (e.g., carbon dioxide fertilization, nitrogen deposition, or precipitation changes), natural effects, and past practices on forested agricultural lands. This book summarizes a September 2003 workshop where leaders from academia, government and industry came together to discuss the current state of scientific understanding on quantifying direct human-induced change in terrestrial carbon stocks and related changes in greenhouse gas emissions and distinguishing these changes from those caused by indirect and natural effects.

The confirmed case of "mad cow" disease (BSE) in June 2005 illustrates the economic impact of disease outbreaks, as additional countries closed their markets to U.S. beef and beef products. Emerging diseases also threaten public health--11 out of 12 of the major global disease outbreaks over the last decade were from zoonotic agents (that spread from animals to humans). Animal Health at the Crossroads: Preventing, Detecting, and Diagnosing Animal Diseases finds that, in general, the U.S. animal health framework has been slow to take advantage of state-of-the-art technologies being used now to protect public health; better diagnostic tests for identifying all animal diseases should be made a priority. The report also recommends that the nation establish a high-level, authoritative, and accountable coordinating mechanism to engage and enhance partnerships among local, state, and federal agencies, and the private sector.

The glassy-winged sharpshooter is one of the more recent invasive pests to afflict California agriculture. The insect transmits a bacterial pathogen that causes Pierce's disease, which has impaired production of wine, table, and raisin grapes in California. The report recommends strengthening the process and the priorities for research funded by state agencies and wine industry groups to address Pierce's disease and its vector. Research should be focused on identifying feasible options for controlling the spread of the disease and providing sustainable approaches that are adaptable and affordable over the long term. Several avenues of research be pursued more intensely including the genetic makeup of the pathogen that triggers Pierce's disease, understanding the mechanisms that make grapes resistant to the disease, the possibilities of introducing predator enemies to the sharpshooter, and new ways to manage the planting of crops to help avoid spread of the disease.

This report follows up on an interim report released in February 2004 that focused on immediate needs in the areas of animal care and management, recordkeeping, and pest control. The report finds that the zoo has made good-faith efforts to correct deficiencies noted in the interim report and has made some noticeable improvements in the past year in zoo operations and animal care. However, problems in areas such as staff training, workplace culture, and strategic planning still need to be addressed. Specifically, the report recommends that the zoo immediately develop and implement animal-care training programs to ensure that people who are directly responsible for the well-being of its animal collection are adequately prepared and competent. The report commends a zoo-initiated strategic planning process as a positive step, but recommends it contain a more detailed, comprehensive strategy of how it will meet short-term goals and that it should link plans to upgrade facilities with those to acquire animals. The zoo should also focus on improving communication among keepers, veterinarians, nutritionists, senior managers, and curators.
