Both land-use change and climate change are important drivers for water resources, and understanding the direction, magnitude, and timing of these influences can be challenging.  Another key challenge is to connect and communicate this science to water users, landowners, policy makers and program developers to help them adapt to changing conditions and find effective approaches for managing water and other ecosystem services.  Drawing on examples spanning from the Oregon Cascades to the Ecuadorian Andes to global syntheses, Dr. Farley will examine challenges associated with gaps in the scientific understanding of the effects of land-use and climate change on water resources and other ecosystem services as welll as efforts to fill gaps in communicating the science to stakeholders.
