One of the main outcomes of the eleven meetings of the Working Party was the recognition of the importance of interdisciplinary studies linking regional geochemistry with plant, animal and human health. The effects of major element deficiencies or excesses on plant health are well known; this is not the case for trace elements. In fact, rapid and reliable analytical methods for determining trace element abundances have only recently become available, and it is to be expected that important new information on trace element levels will be forthcoming. This, however, is only part of the problem because other factors such as element speciation, uptake and transmission may be more significant than total concentration. The pathways of elements from crops to animals are relatively well defined, but the aetiology of diseases attributable to elemental inadequacies or excesses is generally quite complex. Nevertheless, there is good evidence for diseases in livestock in the British Isles induced by deficiencies of Cu, Se and Co and Mo excess. On a world scale there is also convincing data on the effect of Na, P and I deficiencies and F excess on animal health. What is generally lacking, however, is adequate interaction between geochemists and biochemists, veterinary scientists and other concerned with animal health. Interpretation of geochemical data is complex as are connections between elemental abundances and the health of animals.

MULTI-SCALE BIOGEOCHEMICAL PROCESSES IN SOIL ECOSYSTEMS Provides a state-of-the-art overview of research in soil biogeochemical processes and strategies for greenhouse gas mitigation under climate change Food security and soil health for the rapidly growing human population are threatened by increased temperature and drought, soil erosion and soil quality degradation, and other problems caused by human activities and a changing climate. Because greenhouse gas emission is the primary driver of climate change, a complete understanding of the cycles of carbon and major nutritional elements is critical for developing innovative strategies to sustain agricultural development and environmental conservation. Multi-Scale Biogeochemical Processes in Soil Ecosystems: Critical Reactions and Resilience to Climate Changes is an up-to-date overview of recent research in soil biogeochemical processes and applications in ecosystem management. Organized into three parts, the text examines molecular-scale processes and critical reactions, presents ecosystem-scale studies of ecological hotspots, and discusses large-scale modeling and prediction of global biogeochemical cycles. Part of the Wiley - IUPAC Series on Biophysico-Chemical Processes in Environmental Systems, this authoritative volume: Provides readers with a systematic and interdisciplinary approach to sustainable agricultural development and management of soil ecosystems in a changing climate Features contributions from an international team of leading scientists Examines topics such as soil organic matter stabilization, soil biogeochemistry modeling, and soil responses to environmental changes Discusses strategies for mitigating greenhouse gas emission and improving soil health and ecosystems resilience Includes an introduction to working across scales to project soil biogeochemical responses to climatic change Multi-Scale Biogeochemical Processes in Soil Ecosystems: Critical Reactions and Resilience to Climate Changes is essential reading for scientists, engineers, agronomists, chemists, biologists, academic researchers, consultants, and other professionals whose work involves the nutrient cycle, ecosystem management, and climate change.

Research Council established the Ecosystems Panel in response to a request from the United States Global Change Research Program (USGCRP). The panel's charge included periodic reviews of the ecosystems aspects of the USGCRP, and this is the first of those reviews. It is based on information provided by the USGCRP, including Our Changing Planet (NSTC 1997 and earlier editions 1); ideas and conversations provided by participants in a workshop held in St. Michaels, Maryland, in July 1998; and the deliberations of the panel. In addition, the panel reviewed the ecosystems chapter of the NRC report Global Environmental Change: Research Pathways for the Next Decade (NRC 1999a, known as the Pathways report). The USGCRP is an interagency program established in 1989 and codified by the Global Change Research Act of 1990 (PL 101-606). The USGCRP comprises representatives of the departments of Agriculture, Commerce (National Oceanic and Atmospheric Administration and National Institute of Standards and Technology), Defense, Energy, Health and Human Services (the National Institute of Environmental Health Sciences), Interior, and State, as well as the Environmental Protection Agency, the National Aeronautics and Space Administration, the National Science Foundation, the Smithsonian Institution, the Office of Science and Technology Policy, the Office of Management and Budget, and the intelligence community (NSTC 1997). The USGCRP's research program is described in detail in Our Changing Planet (NSTC 1997, 1999). In brief, the program focuses on four major areas of earth-system science: 1) Seasonal to interannual climate variability; 2) Climate change over decades to centuries; 3) Changes in ozone, ultraviolet (UV) radiation, and atmospheric chemistry, and 4) Changes in land cover and in terrestrial and aquatic ecosystems. The fourth topic is the area in which advice was requested from the ecosystems panel. The Ecosystems Panel's charge has three parts: to provide a forum for the discussion of questions of ecosystem science of interest to scientists in and out of the federal agencies, to periodically review the ecosystem aspects of the USGCRP's research program, and to help identify general areas of ecosystem science that need additional attention, especially areas that cut across ecosystems and levels of ecological organization. In addressing the second item of its charge for this report, the panel first identified the most significant and challenging areas in ecosystem science, then used that identification as a basis to make recommendations to the USGCRP. Thus, this report is not a detailed review of the USGCRP's program, but rather an attempt to identify those areas that the panel concludes are most in need of attention by a general research program on global change. As noted in this report, some of those areas are already receiving attention by the USGCRP.

Geology and Health is an integration of papers from geo-bio-chemical scientists on health issues of concern to humankind worldwide, demonstrating how the health and well-being of populations now and in the future can benefit through coordinated scientific efforts. International examples on dusts, coal, arsenic, fluorine, lead, mercury, and water borne chemicals, that lead to health effects are documented and explored. They were selected to illustrate how hazards and potential hazards may be from natural materials and processes and how anthropomorphic changes may have contributed to disease and debilitation instead of solutions. Introductory essays by the editors highlight some of the progress toward scientific integration that could be applied to other geographic sites and research efforts. A global purview and integration of earth and health sciences expertise could benefit the future of populations from many countries. Effective solutions to combat present and future hazards will arise when the full scope of human interactions with the total environment is appreciated by the wide range of people in positions to make important and probably expensive decisions. A case to illustrate the point of necessary crossover between Geology and Health was the drilling of shallow tube wells in Bangladesh to provide non-contaminated ground water. This "good" solution unfortunately mobilized arsenic from rocks into the aquifer and created an unforeseen or 'silent' hazard: arsenic. Geologists produce maps of earth materials and are concerned with natural processes in the environment with long time-frame horizons. The health effects encountered through changing the water source might have been avoided if the hydrological characteristics of the Bangladesh delta had been known and any chemical hazards had been investigated and documented. A recurrence of this type of oversight should be avoidable when responsible parties, often government officials, appreciate the necessity of such integrated efforts. The book extols the virtues of cooperation between the earth, life and health sciences, as the most practical approach to better public health worldwide.
