Pesticide use has changed considerably over the past five decades. Rapid growth characterized the first 20 years, ending in 1981. The total quantity of pesticides applied to the 21 crops analyzed grew from 196 million pounds of pesticide active ingredients in 1960 to 632 million pounds in 1981. Improvements in the types and modes of action of active ingredients applied along with small annual fluctuations resulted in a slight downward trend in pesticide use to 516 million pounds in 2008. These changes were driven by economic factors that determined crop and input prices and were influenced by pest pressures, environmental and weather conditions, crop acreages, agricultural practices (including adoption of genetically engineered crops), access to land-grant extension personnel and crop consultants, the cost-effectiveness of pesticides and other practices in protecting crop yields and quality, technological innovations in pest management systems/practices, and environmental and health regulations. Emerging pest management policy issues include the development of glyphosate-resistant weed populations associated with the large increase in glyphosate use since the late 1990s, the development of Bt-resistant western corn rootworm in some areas, and the arrival of invasive or exotic pest species, such as soybean aphid and soybean rust, which can influence pesticide use patterns and the development of Integrated Pest Management programs.

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 useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"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.

New data continually indicate that antioxidants may contribute to reductions in cancer risks and that chronic consumption of low levels of chemical carcinogens in our diet may contribute to an increased risk of developing specific types of cancers. Research also shows that in America today, the leading causes of death are cancer and heart disease.

Groundwater is endangered and polluted in several ways. Conservation and better management of this invisible resource should be a key ingredient of sustainable water policies. This is especially true in areas, such as many Mediterranean regions, which are already exposed to scarcity problems and which are likely to experience increasing competition between freshwater uses and users. Agriculture is an important user of groundwater not only in terms of abstractions, but also in terms of generation and release of pollutants. Agricultural policies, traditionally directed towards other objectives, are beginning to pay more attention to environmental considerations. However more effective initiatives are required to reduce the pressure upon groundwater resources and to achieve a better integration between agricultural and environmental policies. This book has been developed from three workshops held as part of the EU Concerted Action SAGA, "Sustainable Agricultural Use of Aquifers in Southern Europe: Integration between Agricultural and Water Management Policies" (FAIR5-CT97-3673). The Concerted Action and the workshops brought together researchers working in different but complementary fields, in order to get a picture of the state-of-the art about interlinkages between agriculture and groundwater, as well a critical review of alternative regulatory approaches and policy instruments aimed at improving groundwater management.
