Land-use/Land-cover Change Modeling

Approximately 35% of the US and approximately 82% of DOI lands are “drylands” found throughout the western US. These lands contain oil, gas, oil shale, shale oil, and tar sand deposits and the exploration for and extraction of these resources has resulted in hundreds of thousands of operating and abandoned wells across the West. These arid and semi-arid lands have unique soil and plant communities...

The USGS is collaborating with researchers from other agencies, academia, and industry to predict coastal impacts from hurricanes. The results from this study will better inform coastal morphological change models, which will lead to improved hurricane impact projections.

Tidal marsh vegetation grows in a narrow elevation zone between sea level and the upland behind it. These plant communities have evolved to accumulate sediment over time and maintain their relative elevation with gradual rates of change in sea level. It is uncertain which marsh vegetation communities will be able to accumulate sediment at a rate that keeps pace with accelerated sea level rise.

Overview of Nisqually River Delta ecosystem services modeling

Understanding the rates and causes of land-use/land-cover (LULC) change helps answer questions about what, where, how, and why the Earth’s surface is changing. Land-surface change results from human activities or natural processes like floods, droughts, and wildfires, and many of these change processes are observable in satellite imagery. The growing historical catalog of satellite images allows...

We are a research team focusing on understanding the rates, causes, and consequences of land change across a range of geographic and temporal scales. Our emphasis is on developing alternative future projections and quantifying the impact on environmental systems, in particular, the role of land-use change on ecosystem carbon dynamics. We are interested in how land-use and climate systems will...

Land Cover Trends was a research project focused on understanding the rates, trends, causes, and consequences of contemporary U.S. land use and land cover change. The project spanned from 1999 to 2011. The research was supported by the Climate and Land Use Change Research and Development Program of the U.S. Geological Survey (USGS) and was a collaborative effort with the U.S. Environmental...

By using the USGS- developed, GIS-based tool, we can automate the dasymetric mapping process. We have worked with various communities to create accurate population density maps to aid in risk and vulnerability analysis linked to natural hazards. By using the USGS- developed, GIS-based tool, we can automate the dasymetric mapping process. We have worked with various communities to create accurate...
