Environmental Protection AgencyPrincipal Areas of Focus
The planning and implementation of EPA’s program is integrated by the CCSP with other participating Federal departments and agencies to reduce overlaps, identify and fill programmatic gaps, and add EPA’s program also makes significant contributions to the high-level interagency bilateral climate dialogues that are led by the Department of State. EPA’s program supports research on climate impacts and adaptation in China, Italy, Canada, and India. These activities focus on evaluating the potential consequences of climate change and adaptation strategies. EPA’s program has four areas of emphasis: air quality, water quality, ecosystems, and human health. The results of studies done in these areas are integrated at particular places (such as watersheds). Air QualityStudies are planned that will examine the potential consequences of global change on air quality in the United States. The long-term goal of this focus area is to provide the approaches, methods, and models to quantitatively evaluate the effects of global change on air quality, and to identify technology advancements and adaptive responses and quantify their effect on air quality.Water QualityWater quality is affected by changes in runoff following changes in precipitation and evapotranspiration and/or changes in land use. The program is investigating the possible impacts of global change (climate and land-use change) on water quality using a watershed approach. The water quality studies will contribute to and benefit from human health and ecosystems studies.EcosystemsEPA’s mission is not only to protect human health but also to safeguard the natural environment. EPA provides environmental protection that contributes to making communities and ecosystems diverse, sustainable, and economically productive. Consistent with this goal, EPA’s Global Change Research Program has planned three research activities that evaluate the effects of global change on aquatic ecosystems (which may include lakes, rivers, and streams; wetlands; and estuaries and coastal ecosystems); invasive nonindigenous species; and ecosystem services. EPA’s investigations of the effects of global change on aquatic ecosystems will use as input the research being done by other CCSP agencies on marine and terrestrial ecosystems. Therefore, EPA’s ability to successfully complete its assessments depends crucially upon the ability of other CCSP agencies to complete their related research activities.Human HealthSince health is affected by a variety of social, economic, political, environmental, and technological factors, investigating the health impacts of global change is a complex challenge. As a result, health studies in EPA’s Global Change Research Program go beyond basic epidemiological research to develop integrated health evaluation frameworks that consider the effects of multiple stresses, their interactions, and human adaptive responses. Along with health sector studies conducted in conjunction with other CCSP agencies, there are research activities focused on the possible consequences of global change on weather-related morbidity and vector- and water-borne diseases. In addition, the results from EPA’s Global Change Research Program air quality studies will be used to evaluate health consequences.Intramural and extramural research contribute to all of EPA’s investigations. In an attempt to capitalize on expertise in the academic community, a significant portion of the program’s resources is dedicated to Program Highlights for FY 2007EPA will continue to make significant contributions to the ongoing research activities of the CCSP. EPA-sponsored investigations will continue to be conducted through public-private partnerships that actively engage researchers from the academic community, decisionmakers, resource managers, and other affected stakeholders. Highlights of specific activities that will be undertaken by EPA in FY 2007 follow:
Related ResearchIn addition to focused CCSP activities, EPA conducts research that contributes to the characterization and understanding of risks to ecosystems and to human health. The ecosystems-based research is designed to understand and predict ecosystem exposure, responses, and vulnerabilities to high-risk chemicals and non-chemical stressors (e.g., invasive species, genetically altered organisms) at multiple scales of biological organization and geographic scales. The research in human health is oriented toward assessing the cumulative health risks to humans (e.g., cancer, reproductive, cardiovascular)—including high-risk subpopulations (e.g., children)—from chemical stressors emanating from multiple sources. Both of these major research areas will be affected by and are inextricably interrelated with climate change.
