Abstract: | In this article we present a framework for assessing climate change impacts on water and watershed systems to support management
decision-making. The framework addresses three issues complicating assessments of climate change impacts—linkages across spatial
scales, linkages across temporal scales, and linkages across scientific and management disciplines. A major theme underlying
the framework is that, due to current limitations in modeling capabilities, assessing and responding to climate change should
be approached from the perspective of risk assessment and management rather than as a prediction problem. The framework is
based generally on ecological risk assessment and similar approaches. A second theme underlying the framework is the need
for close collaboration among climate scientists, scientists interested in assessing impacts, and resource managers and decision
makers. A case study illustrating an application of the framework is also presented that provides a specific, practical example
of how the framework was used to assess the impacts of climate change on water quality in a mid-Atlantic, U.S., watershed. |
