Land Change Science Program

Home

Changes in the environment, land use, and climate can have significant impacts on our Nation’s economy, natural resources, infrastructure, and water, food, and energy security. To strengthen our Nation’s ability to respond and adapt to these stressors, the USGS Land Change Science Program conducts research to improve understanding of rates, causes, and consequences of climate and land use change.

Data and Tools

Climate history, land cover and land surface data and models are vital for assessing the impacts of climate change, evaluating ecosystem status and health, understanding spatial patterns of biodiversity, and informing land use planning.

New Land Cover Maps Depict 15 Years of Change across America

Today, the U.S. Geological Survey (USGS) released the latest edition of the National Land Cover Database (NLCD) for the U.S. – the most comprehensive land cover database that the USGS has ever produced. The NLCD 2016 documents land cover change in the Lower 48 states from 2001 to 2016. During this 15-year period, 7.6 percent of the conterminous U.S. changed land cover at least once.

LCS-funded Scientist's Work Highlighted as USGS Top Story

LCS-funded scientist, Kristen Manies, recently had her research with methane sensing drones highlighted as a USGS top story. The work uses unmanned aircraft to “sniff” methane gas escaping from thawing permafrost. Learn more about the amazing work she's a part...

National Climate Change Viewer data used in an evaluation comparing statistical downscaling methods and data sets

A comprehensive evaluation comparing hydroclimate projections derived from six statistically downscaled data sets, including data underpinning the National Climate Change Viewer (NCCV) was recently published.

The dependence of hydroclimate projections in snow‐dominated regions of the western United States on the choice of statistically downscaled climate data

We assess monthly temperature and precipitation data produced by four statistically based techniques that were used to downscale general circulation models (GCMs) in the Climate Model Intercomparison Program Phase 5 (CMIP5) (Taylor et al., 2012). We drive a simple water-balance model with the downscaled data to demonstrate the effect of the...

Arctic vegetation, temperature, and hydrology during Early Eocene transient global warming events

Early Eocene global climate was warmer than much of the Cenozoic and was punctuated by a series of transient warming events or ‘hyperthermals’ associated with carbon isotope excursions when temperature increased by 4–8° C. The Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma) and Eocene Thermal Maximum 2 (ETM2, 53.5 Ma) hyperthermals were of short...

Simulating the effects of climate variability on waterbodies and wetland-dependent birds in the Prairie Pothole Region

Understanding how bird populations respond to changes in waterbody availability in the climatically variable Prairie Pothole Region (PPR) of North America hinges on being able to couple hydrological and climate modeling to represent potential future landscapes. Model experiments run with the Pothole Complex Hydrologic Model using downscaled...
