The NASA Land Cover/Land Use Change (LCLUC) Program awarded the University of North Carolina at Chapel Hill a three-year grant in the amount of $720,000 to examine the effects of social and ecological factors, particularly, human migration and tourism on the environment and on the sustainability of island ecosystems. The principal investigator is Stephen J. Walsh, Lyle V. Jones Distinguished Professor of Geography at UNC and director of the Center for Galápagos Studies.

While the Galápagos Islands are the central area of study for the grant, the project also includes Hawaii and Puerto Rico, as well as islands selected from around the globe that are similarly challenged by the multi-scale and multi-dimensional threats to island ecosystems and their sustainability.

Walsh specializes in satellite remote sensing, spatial simulation models, and population-environment interactions, and the NASA grant will support him and his co-investigators in their examination of the environmental impacts of economic development on remote island ecosystems. The grant, titled “Synthesis of Drivers, Patterns, and Trajectories of LCLUC in Island Ecosystems,” will explore the LCLUC that profoundly affects the natural environment in places like Hawaii, Fiji and the Canary Islands. An improved understanding of these connections is critical for identifying the effects of changing environments on exotic island ecosystems and explaining the impacts of the tourism industry and environmental and economic transitions on broader land use issues.
