Aquatic Ecosystems, Water Quality, and Global Change: Challenges of conducting Multi-Stressor Vulnerability Assessments (External Review Draft)
EPA is annnouncing the release of the draft report, Aquatic Ecosystems and Global Change: The Challenges of conducting Multi-Stressor Global Change Vulnerability Assessments, for public review and comment. This draft report investigates the issues and challenges associated with identifying, calculating, and mapping indicators of the relative vulnerability of water quality and aquatic ecosystems to long-term forcings like land-use and climate change. The external peer review period is 8 weeks, and the public comment period is 45 days.[Federal Register Feb 28, 2011]

Impact/Purpose:
This draft report investigates the issues and challenges associated with identifying, calculating, and mapping indicators of the relative vulnerability of water quality and aquatic ecosystems, across the United States, to the potential adverse impacts of external forces such as long-term climate and land-use change.
Description:
This draft report investigates the issues and challenges associated with identifying, calculating, and mapping indicators of the relative vulnerability of water quality and aquatic ecosystems, across the United States, to the potential impacts of global change. Using a large set of environmental indicators drawn from the scientific and management literature, this draft report explores the conceptual and practical challenges associated with using such indicators to assess how the resilience of ecosystems and human systems may vary as a function of existing stresses and maladaptations.
