2008 Rachel Carson Lecture by Ruth DeFries

Ruth DeFries delivered the 2008 Rachel Carson Lecture, "Changing Dynamics of Tropical Deforestation and  Atmospheric Carbon Emissions: Science Meets Policy," on March 18, 2008 in the Red Cedar Room of the Kellogg Center. View DeFries' handouts for the lecture.

DeFries is a member of the U.S. National Academy of Sciences, a fellow of the American Association for the Advancement of Science, a recipient of the MacArthur Foundation Prize and a fellow of the Aldo Leopold Leadership Program. She is currently professor of geography and earth system science in the  Interdisciplinary Center at the University of Maryland.

DeFries’ research investigates the relationships among human transformation of the land surface and the biogeochemical and ecological processes that regulate the Earth’s habitability. The research uses satellite imagery as a lens to examine changes in the land surface over large areas. The overall thrust of the research is to develop underlying science for balancing the needs of human society to transform the landscape for food production, settlements and other requirements while maintaining long-term habitability of the planet.
