The Western Geographic Science Center conducts research to help communities make decisions about the interaction between people and their environment. We conduct geographic research on the environmental and societal consequences of a changing landscape.

Our projects analyze human / environmental interactions spatially and temporally. Our work is collaborative, involving many partners and linking many different natural science and social science disciplines. Our work is concentrated in the 9 states of the USGS Western Region and is conducted on local and regional scales.

Tsunami Emergency Managers Meeting, Huntington Beach Lifeguard Headquarters

Nathan Wood PresentingHuntington Beach Tsunami Evacuation Map

Nathan Wood and Jeff Peters met with tsunami researchers from NOAA, CalOES, CGS and Emergency Managers from various California coastal communities to talk about their recent research in tsunami evacuation modeling. Others topics discussed include: tsunami early warning systems, aircraft based warning systems for rural areas, potential multi-phase evacuation plans, and updates on requirements for communities to qualify as TsunamiReady.

Home on the California Range, Year 2100: Land Use and Climate Change Could Impact Wildlife, Water Supplies

erosion structures

Grassland habitats on rangelands in California’s Central Valley and surrounding foothills could decline by as much as 37 percent by 2100 due to changes in land use and climate, according to new scientific projections by the U.S. Geological Survey.

“Results from this study reinforce the role of open rangelands in capturing water and reducing runoff,” said Dr. Kristin Byrd, the study’s lead author and a physical scientist with the USGS. “Maintaining rangelands can help mitigate the effects of climate change and drought.”

The complete research paper, “Integrated climate and land use change scenarios for California rangeland ecosystem services: wildlife habitat, soil carbon, and water supply,” by Kristin Byrd and others was recently released online in the journal “Landscape Ecology.”
