This book focuses on current food shortages and on the impact of pests in reducing world food supplies. At present, total worldwide food losses from pests are estimated to be about 45 percent. Preharvest losses alone, from insects, plant pathogens, and weeds, are estimated at about 30 percent. Additional postharvest losses from microorganisms, insects, and rodents range from about 10 to 20 percent. The contributors present data on the extent of these kinds of crop losses and analyze immediate and long-term pest management strategies. Emphasis is given to an evaluation of the effectiveness of integrated controls and the various new nonchemical pest controls used to reduce crop and livestock losses. The current worldwide environmental problems associated with both large-scale pesticide use and other pest control methods are also analyzed, including the impact that increased use of pesticides can be expected to have on the human environment. While the data included are technical, the presentation and analysis will be of interest to both the scientific community and the general public.

The field of pest control research, of increasing importance in a world short of food, has been plagued for many years by a variety of problems, among them (1) the instability (including pesticide resistance) of many control techniques, (2) the continuing need for improved pest management methods to increase world food supplies, and (3) the environmental and social hazards of currently used pesticides. What historical or other factors affect the ability of science to generate useful new technologies to alleviate these three major problems? Are there barriers to cooperation among the different pest control specialists? This book attempts to answer these questions, examining past events and projecting likely impacts on contemporary pest management systems. The authors--sociologists, economists, lawyers, ecologists, political scientists, and pest control scientists--examine the social, economic, political, and ethical factors that are important in shaping pest management systems, as well as developmental patterns that show the importance of these factors in shaping today's systems.

Pesticides have contributed impressively to our present-day agricultural productivity, but at the same time they are at the centre of serious concerns about safety, health and the environment. Increasingly, the public wonders whether the benefits of pesticides - the perfect red apple - "outweigh the costs of environmental pollution, human illness, and the destruction of animals and our habitat". Scientists and government officials are suspected of promoting commercial interests rather than protecting human welfare. This volume is the result of more than a year's study by leading scientists and policy experts who address the environmental, economic, ethical and health issues related to pesticides. In examining the social policies related to pesticide use, they consider the risks as well as the benefits. They show that to regain public trust, those who regulate and use pesticides must examine fair ethical questions and take appropriate action to protect public welfare, health and the environment.Anyone concerned with reducing our reliance on chemical pesticides and with how human activities can remain both productive and environmentally sound should find this volume of interest in a troubling debate. This book should be of interest to ecologists and environmentalists.

This book outlines the techniques for reducing pesticide use internationally through using integrated pesticide management, and assesses the resulting environmental and economic benefits. The goal of the book is to focus on reducing pesticide use, not eliminating it, in order to maintain yields and current cosmetic food standards and provide a sustainable agriculture.

Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30-50% of the earth's land surface. At the time of the first publication of this book in 1993, estimates indicated that 10-15 million hectares of land were being lost each year through erosion and salinisation from irrigation and that at such a rate of loss, topsoil reserves on most sloping lands would be depleted within two hundred years. Since humankind's dependency on the land for food is almost total, soil erosion represents a real threat to the security of our food supply. The need for the immediate conservation of the world's soil resources is therefore clear. As part of the response to this need, the International Union for the Conservation of Nature's Commission on Ecology convened a special working group to consider the problem of world soil erosion and to propose practical solutions for soil conservation. This important book presents the outcome of their work.

Chemical pesticides continue as a point of major controversy in our society. Increasingly stringent regulatory actions on the part of state and federal agencies, exemplified by the RPAR (Rebuttable Presump­ tion Against Registration) program of the Environmental Protection Agency, are supported by environmental groups and are generally op­ posed or viewed with skepticism by agriculturalists. The energy crisis invokes other questions on benefits of pesticides versus nonchemical controls and effects on labor utilization. As DDT and other persistent pesticides have been phased out, the more labile, short-lived chemicals have filled the voids in pest management systems; and effects on nontarget species appear to have declined in recent years as the shift occurred. However, nagging ques­ tions of the hazard to man and other nontarget species from long-term, low-level exposure to pesticides are frequently raised; and recent suggestions that certain well-known and long-used chemicals cause cancer, increase sterility, and initiate or augment other deleterious effects in test animals have instilled a sense of caution and raised con­ cern about the continued availability of some pesticides previously considered safe. So the facade of concern and confusion continues. This book is an outgrowth of a symposium at the meeting of the American Association for the Advancement of Science in February, 1978. An introduction has been added, and some of the papers have been modified since presentation.

Judicial reform became a priority for international development in the 1990s and remains central to EU enlargement conditionality today. Yet despite significant investment, there is limited empirical evidence about the effectiveness of these initiatives. This book addresses this gap through a comprehensive longitudinal study of Bosnia and Herzegovina's post-war judicial reforms.Drawing on unique survey data from judges and prosecutors, it provides the first long-term empirical assessment of post-conflict judicial reform outcomes. The findings reveal a complex picture: while reforms successfully established judicial independence and insulated courts from ethnic politics, they also created new vulnerabilities to corruption and impunity. The book demonstrates that judicial independence, when introduced without adequate integrity safeguards, can become counterproductive to rule of law objectives. Considering original survey data spanning more than two decades of post-reform implementation, it offers a critical analysis of judicial independence and accountability tensions and evidence-based insights for EU conditionality and development policy.It will be of interest to scholars and students of comparative law, transitional justice, and development studies, challenging prevailing assumptions about judicial independence, particularly in post-conflict settings.

Biofuels and food are dependent on the same resources for production: land, water, and energy. The conjuncture of food, energy, and climate crises demands a new direction in how to harness agriculture to the joint tasks of energy-saving, emissions reduction, and food security. Global Economic and Environmental Aspects of Biofuels focuses on the all-important question of the efficacy of biofuels as a solution to the global energy problem. Written by a distinguished team from five countries and multiple disciplines including agronomy, petroleum engineering, ecology, and meteorology, the book addresses the use of biofuels produced from crops and various organic materials as alternatives or supplements to petroleum. Key Features Discusses biofuels within the context of the world population problem, food, malnutrition, resource depletion, and climate change Asks the critical question whether the production of ethanol from corn, sugar cane, crop residues, and other organic materials has proven too costly in both economic and environmental termsAnalyzes the uses and interdependencies among land, water, and fossil energy resources in food versus biofuel production Includes case studies on the economic and environmental impacts of biofuel production and use from the United States, Europe, Brazil, and tropical environmentsExplores the future production of biodiesel and ethanol from salt-water algae and tropical palms, while recognizing the technological problems that must be resolved in processing these materialsThis book examines key environmental and economic issues associated with the production of ethanol as a fuel, from corn, sugar cane, crop residues, and other organic materials. It brings together the opinions of a number of U.S. scientists and experts from Spain, Italy, the United Kingdom, and Brazil, and highlights the remarkable agreement among the contributors on the pros and cons of biofuels as an answer to future petroleum shortages. This mix of contributors and opinions presents a well-rounded view of the subject that puts a spotlight on unresolved concerns and complexities that are often overlooked.

The aim of this volume is to collect and present available data, both published and unpublished, on energy use in agriculture and forestry production. Energy analyses for some sciences such as ecology are not new, but their applications to agriculture started in 1973. These analyses have grown rapidly in number and complexity. This handbook is intended for agriculturalists and others concerned with energy use in crop, livestock, and forestry production.
