Climate and Land Use Change Effects on Ecological Resources in Three Watersheds: A Synthesis Report (Final Report)

Notice

EPA announces the release of the final report, Climate and Land-Use Change Effects on Ecological Resources in Three Watersheds: A Synthesis Report.


Abstract

Cover of the Synthesis Report on Climate and Land Use Change Effects on Ecological Resources in Three Watersheds The purpose of this final report is to provide a summary of climate change impacts to selected watersheds and recommendations for how to improve the process of conducting watershed assessments in the future.

During the early 2000s, the Environmental Protection Agency’s (EPA’s) Office of Research and Development, Global Change Research Program, supported three watershed assessments to evaluate different approaches and tools for understanding and managing climate and land use change impacts on watershed ecological resources. Watershed assessments were conducted for (1) several small rivers in southern Maryland, (2) Arizona’s San Pedro River, and (3) California’s Sacramento River. In this report, we comparatively analyze the three case study approaches in order to develop recommendations that may be useful as guidance to others conducting similar assessments.

The watershed assessment case studies described in this report yield richness of detail in terms of methods and results, as well as inform more generally on best practices for conducting future watershed assessments. However these were pioneering studies addressing difficult and complex problems. Future assessments will continue to refine the understanding of how to maximize decision support, including providing necessary keystone capabilities and tools to effectively estimate climate change vulnerabilities, developing and supporting successful stakeholder processes, and characterizing uncertainty and scaling or transferring results to increase their relevance.
