Jeff Opperman, Ph.D., lead scientist for The Nature Conservancy’s Great Rivers Partnership, has been working to protect rivers and lakes for more than 15 years. He has provided strategic and scientific guidance to freshwater conservation projects across the United States as well as in China, Africa and Latin America. Through strategy development, scientific research, and support to field projects, Jeff focuses on protecting and restoring river-floodplain ecosystems and improving the environmental sustainability of hydropower.

Jeff describes how the world can achieve a future with both sustainable energy and healthy rivers.
Shoot Out the Lights: Science, Hydropower & Reality on the Mekong
The standard story: big dams disrupt the livelihoods of rural villages. But many communities welcome development; Jeff asks, can conservation minimize hydropower impacts?
Jeff and Qiaoyu Guo make the case that conservationists need a broader vocabulary to deal with dams than just the word “no."
Fighting dams is in the environmental movement's DNA. But is it time to change? Jeff argues that science-based collaboration offers a better future for rivers and fish -- and the people who depend on them.
Dam removal on Maine's Penobscot River means a brighter future for Atlantic salmon and other migratory fish. But an even greater value of the Penobscot may in fact lie in its meaning for countries that are just now beginning to plan and build dams. Jeff explores the possibilities.
Jeff writes about the value conservation adds to peoples' lives.
Floods destroy, Jeff writes, but they also create.
Jeff reflects on the 2011 Mississippi floods by focusing on what worked — and how we can build on it for even better river management.
Jeff discusses the American penchant to live where it’s sunny and why that’s bad for water sustainability.
Water doesn’t come from the tap or grocery store shelves, Jeff writes. It comes from nature. We need nature for clean water.
In a personal tribute to his area of expertise, Jeff discusses why he’s always been drawn toward rivers.
Jeff writes on the importance of the world’s deltas and why human activity is threatening these valuable resources.

Jeff Opperman, Ph.D.
Lead Scientist, Great Rivers Partnership
Jeff Opperman, lead scientist, has been working to protect rivers and lakes for more than 15 years. He has provided strategic and scientific guidance to freshwater conservation projects across the United States as well as in China, Africa and Latin America.
For the Nature Conservancy, Jeff leads a team that focuses on developing strategies for conserving rivers and improving the environmental sustainability of hydropower.
Jeff earned his B.S. in Biology from Duke University and a Ph.D. in Ecosystem Science from the University of California, Berkeley. He then studied floodplain ecology during a post-doctoral fellowship at the University of California, Davis. His scientific and policy research has been published in journals such as Science, BioScience and Ecological Applications. Jeff strives to communicate the challenges and opportunities of protecting fresh water through op-eds, articles and blog posts in such places as The New York Times, Outside, Grist, and The Guardian.
