"The assessment was done using measurements derived from satellite imagery and spatial data bases. The information presented in this atlas is intended to help the reader visualize and understand the changing conditions across the region and how the pattern of conditions can be used as a context for community-level situations. This atlas was developed as part of the Environmental Monitoring and Assessment Program (EMAP) and is part of a larger, multi-organizational effort to assess environmental condition in the mid-Atlantic region."--From the publisher.

This book examines environmental security from the perspective of landscape sciences, identifying the forces that threaten environmental security at all levels. It stems from the last five years of the Pilot Study Project on Use of Landscape Sciences for Environmental Assessment sponsored by the NATO Committee on the Challenges of Modern Society. Readers explore concepts of environmental security from subjective and objective perspectives.
The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems. With the controls on point sources reducing chemical contamination, new environmental challenges associated with nonpoint sources have emerged. To adequately deal with these new problems, EPA's Office of Research and Development recognized the need to develop an overall under standing of the condition of our ecological resources, the trends in their condition, and the stressors affecting these systems on a broad scale. Toward this end, the En vironmental Monitoring and Assessment Program (EMAP) was established by EPA and has been strategically developing the scientific tools and techniques to monitor and assess the status and trends of aquatic ecosystems. EMAP scientists have developed new indicators and probability-based de signs to fill data gaps in the development of regional-scale assessments of our aquatic resources, as required in the Clean Water Act. We have a scientifically de fensible approach that allows: 100 percent coverage of the aquatic resources within broad geographic areas and the formulation of reference 'conditions for es tablishing the health of these resources. The use of these indicators and designs were successfully demonstrated in the landscapes, streams, and estuaries of the mid-Atlantic states as part of the Mid-Atlantic Integrated Assessment (MAlA).
The lands and waters of the Mid-Atlantic Region (MAR) have changed significantly since before the 16th century when the Susquehannock lived in the area. Much has changed since Captain John Smith penetrated the estuaries and rivers during the early 17th century; since the surveying of the Mason-Dixon Line to settle border disputes among Maryland, Pennsylvania, and Delaware during the middle of the 18th century; and since J. Thomas Scharf described the physiographic setting of Baltimore County in the late 19th century. As early as 1881, Scharf provides us with an assessment of the condition of the aquatic ecosystems of the region, albeit in narrative form, and already changes are taking place – the conversion of forests to fields, the founding of towns and cities, and the depletion of natural resources. We have always conducted our work with the premise that “man” is part of, and not apart from, this ecosystem and landscape. This premise, and the historical changes in our landscape, provide the foundation for our overarching research question: how do human activities impact the functioning of aquatic ecosystems and the ecosystem services that they provide, and how can we optimize this relationship?
The current rate and scale of environmental change around the world makes the detection and understanding of these changes increasingly urgent. Subsequently, government legislation is focusing on measurable results of environmental programs, requiring researchers to employ effective and efficient methods for acquiring high-quality data. Focusing on pollution issues and impacts resulting from human activities, Environmental Monitoring is the first to bring together the conceptual basis behind the complex and specific approaches to the monitoring of air, water, and land. Coverage includes integrated monitoring at the landscape level, as well as case studies of existing monitoring programs such as the Chesapeake Bay Program. The book also addresses the recent legislative focus on high-quality data results and conducting monitoring programs in different ecosystems and environmental media.
Environmental Indices: Systems Analysis Approach examines the theoretical development of environmental indices and their practical application. Indicators can be powerful tools in guiding data and information collection processes, and careful development will lead to more focused and cost-effective global monitoring and observing systems at international level. The authorship is drawn from a group of internationally distinguished scientists and researches who are actively working towards a comprehensive set of tools and protocols such as simulation models, fuzzy clustering analysis and GIS methodologies that will lead to the development of meaningful environmental indices. This book will be a vital reference work for students, teachers and researches, together with policy makers, planners and all professional involved in development programs.
