N. LeRoy Poff is a Professor in the Department of Biology at Colorado State University and holds a partial appointment in Riverine Science and Environmental Flows in the Institute of Applied Ecology at Canberra Uni in Australia. Prof. Poff is a recognized global leader in the application of theory-driven ecological science to water resources management and freshwater sustainability.

His research and collaborative efforts over the last 30 years have contributed significantly to the scientific development and expansion of the field Environmental Flows. Prof. Poff collaborates extensively with hydrologists, fluvial geomorphologists, and engineers on questions of river resilience in a world of global change. He has published extensively on the ecological consequences of hydrologic alteration and on the expected impacts of climate change on aquatic systems. He also collaborates with and advises several NGOs, including The Nature Conservancy, American Rivers, and Conservation International. He was a keynote speaker at the 2007 Riversymposium and part of the committee responsible for drafting the Brisbane Declaration. He holds several honors, including past President of the Society for Freshwater Science and an elected Fellow of the Ecological Society of America and of the American Association for the Advancement of Science

Keynote presentation: Environmental Flows: A Framework to Achieve Social-Ecological Sustainability in a Changing World

The last 30 years have seen tremendous changes in the science, application and social acceptance of environmental flows. The 2007 Brisbane Declaration was a landmark in the development of the e-flows paradigm, formally recognizing the co-dependence of people and nature on renewable freshwater resources. In the 10 years since, progress in science, management, policy and legislation has elevated e-flows into a globally recognized platform to sustainably manage freshwaters for social and ecological benefit. But the effectiveness of achieving this potential is challenged by increasing demand for freshwater resources and by deep uncertainties about how global warming will affect the reliability of future water and hence potential conflicts among end users. Ecological scientists, water resources engineers and social scientists must innovate collaboratively to design science-based and socially-acceptable management schemes that can sustain human-dominated freshwater ecosystems in a changing world.
