Abstract:The U.S. Environmental Protection Agency's (EPA) Regional Vulnerability Assessment Pro- gram (REVA) is designed to develop and demonstrate approaches to identify the ecosystems at the greatest risk from regional population growth and economic activity (Smith, 1999). A region is a multi-state area involving many metropolitan areas, drainage basins, associated ecosystems, and cultural infrastructures. The term vulnerability is a variable, ranging from no vulnerability to low and high vulnerability; without a qualifier, the term implies nothing. REVA is particularly used to compare risks arising from all sources of potential harm, acting alone or in combination, over the entire region. REVA is beginning with a pilot study conducted as part of the Middle Atlantic Integrated Assessment (MAIA). The study area includes all of Pennsylvania; Maryland; West Virginia; Virginia; the District of Columbia; and parts of North Carolina, Delaware, New York, and New Jersey. This area was selected because it has a wealth of ecological data collected by field surveys, remote sensing, and other ecological monitoring, modeling, and research activities.
The study reported herein addresses two key questions: (1) What will be the land conversion to urban use and nitrogen loading during the next 5 to 25 years? and (2) Where are the most vulnerable ecosystems located? Immediate objectives are these:

1. Integrate multiple data sources and existing assessment technologies
2. Expand research to fill critical gaps in our ability to apply existing data at the regional scale
3. Incorporate socioeconomic research to better understand factors driving environmental change and to more accurately assess the true costs of environmental degradation

REVA will test alternative approaches by applying the technology as it is developed to the MAIA and obtain feedback from decision makers at the regional and local levels and the public.
