This seminar examines how land fragmentation, land cover change, and biodiversity changes — as observed and studied with remote sensing techniques — provide a greater global evaluation of these localized phenomena. Presenter Mathew Hansen is a Professor in the Department of Geographical Sciences at the University of Maryland. He is a remote sensing scientist with a research specialization in large area land cover and land use change mapping.

The AGU Sagan Lecture series is sponsored jointly by the Biogeosciences and Planetary Sciences Sections of AGU and aims to provide perspectives on astrobiology and public engagement on critical issues which transcends boundaries of disciplinary research and planetary boundaries. These lectures topics encompass, integrate, and synthesize multiple disciplines in a unique fashion to explore and to expand our knowledge of life without boundaries.
