The dam dilemma: how to balance hydropower, rivers & people | Jessie Moravek | TEDxFulbrightGlasgow

Hydropower is a renewable resource, but that does not make it sustainable. Jessie Moravek examines the downsides to river hydropower, including declining fish populations, poor water quality and damaged ecosystems. But hydropower can be made sustainable, and Moravek explains how. Advocating for conservation and rivers can ensure that our hydropower is not just renewable, but sustainable for generations to come. Jessie Moravek is a graduate student studying how hydropower dams affect freshwater ecosystems around the globe. Her research focuses on the ecosystem effects of hydropower development in countries like Nepal, where freshwater biodiversity is under-studied and the hydropower industry is growing. She is also interested in dam removal projects, and how ecosystems reshape themselves when rivers are re-opened. Her previous research has focused on Pacific salmon food webs, wetland water quality in the Himalayas, hydropower development in Nepal, and weir removal projects in England. Jessie is currently studying at Lancaster University, England, where she is measuring changes in fish populations in response to river conservation works. Jessie originally hails from St. Charles, Illinois, where she grew up creek stomping and frog hunting in the stream near her house.
