Their study used Geographic Information Systems (GIS) to examine historical changes in land-use and riparian forest cover in the newly established Lake Tana Biosphere Reserve in northern Ethiopia. Contrasting declassified U.S. government aerial photographs from 1964 to 1967 with present-day U.S. Geological Survey Landsat satellite imagery revealed widespread deforestation and riparian vegetation loss over the past 50 years.
Their findings add to the nascent literature on biosphere reserves in more-densely settled, fragmented forest landscapes. The paper began as a project in the environmental studies capstone course with Assistant Professor of Environmental Studies Travis Reynolds.
