Freshwater ecosystems are in trouble. For centuries -- and until very recently -- rivers and ecosystems were always managed using history as a reference point. As we move into an era of uncertainty surrounding climate and hydrology, how should we think about ecosystem management in the future?

In this episode of ClimateReady, we meet with Dr. LeRoy Poff, a Professor in the Department of Biology at Colorado State University and Chair of its Ecology Graduate Program. LeRoy is a leading authority on aquatic ecology and lead author behind the seminal environmental flows (“eflows”) theory on river restoration and management. For the last 20 years, eflow science has been used to guide management and policy around ecosystem performance and natural flow regimes in regulated rivers. However, the underlying assumptions of this theory and practice are being tested by climate change. With an updated take on eflows, LeRoy explains how we must move beyond the natural flow regime to meet the challenges of a non-stationary and changing world.

Following the main interview, we have a “Postcard from the Future” from Stephanie Lyons, a climate, environment, and water consultant with a story from Vietnam.
