Aquatic Ecosystems, Water Quality, and Global Change: Challenges of Conducting Multi-Stressor Vulnerability Assessments (Final Report)
EPA is annnouncing the release of the final report, Aquatic Ecosystems and Global Change: The Challenges of conducting Multi-Stressor Global Change Vulnerability Assessments.
This 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 final 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.
The intent is for this report to be a useful building block for future work on multi-stressor global change vulnerability assessments: (i) to bridge disconnects between the decision support needs of the water quality and aquatic ecosystem management communities and the priorities and capabilities of the global change science data and modeling communities; (ii) to help to synthesize lessons learned from more detailed, place-based, system-based, or issue-based case studies; and (iii) to prioritize future work in developing adaptation strategies for global change impacts.
