How have humans changed rivers throughout history, and what issues of social and environmental justice shape human interaction with rivers and, more generally, water? These questions shape the research of Carson Fellow Melinda Laituri, who is engaged in a comparative study between the Danube and the Colorado River. By using remotely sensed data, Laituri tracks changes in the development of the river; Laituri’s research also examines the human right to water. Melinda Laituri is currently based in the Department of Forest, Rangeland, and Watershed Stewardship at Colorado State University. Her research focuses on the role of the internet and geospatial technologies of disaster management and cross-cultural environmental histories of river basin management.
