The Geographical Sciences Committee (GSC) provides high-quality scientific, technical, and policy advice and recommendations to society and to government at all levels using the methods of spatial analysis and representation. The geographical sciences focus on understanding responses to the impacts of changing biophysical and human environments. Place-based responses in domains ranging from health to urbanization, hazards to migration, can be characterized in terms of vulnerability, resiliency, adaptation, and sustainability. The GSC addresses the geographic dimensions of human-environment interactions, spatial location and concentration, and place-based research and policy at all spatial scales. It is the official U.S. liaison to the IGU.
