About

Changes in the environment, ecosystems, and land use can have significant impacts on our Nation’s economy, natural resources, infrastructure, as well as water, food, and energy security. Research conducted by the Ecosystems' Land Change Science Program provides scientific data to improve projections of change under different management scenarios and strengthen our ability to respond and adapt.

Who We Are and What We Do

 
USGS science helps to understand the causes and effects of environmental change. Ariana Sutton-Grier is the coordinator of the Land Change Science Program in the USGS Ecosystems Mission Area, whose scientists focus specifically on environmental changes that have occurred in the past, are taking place now, or will occur in the future. “We really are doing it all—past, present, and future,” Sutton-Grier said. “We're trying to understand how things like climate change and other environmental changes are affecting our ecosystems.”
Program Mission

The Program is at the frontier of interdisciplinary and integrated scientific research understanding patterns, processes, and impacts (past, present, and future) of changing environment, ecosystems, and land use on the Earth system.

 
Program Objectives 

The Program aims to address pressing socioenvironmental challenges by developing science applications that inform decision making. Current focuses are: 

  • Understanding the processes that influence cycling of water, nutrients, and carbon in terrestrial and aquatic ecosystems including the impacts of environmental extremes and disturbance.
  • Documenting patterns of change, developing a process-based understanding of drivers of change, as well as predicting ecosystem response to change in land use/land cover, environmental conditions, and climate.
  • Using paleoclimate and instrumental records to document magnitudes, patterns, and impacts of past and recent change on North American ecosystems and use this knowledge to improve future climate models.

To address these goals, research is carried out in many ecosystems, including wetlands, tundra and sea ice, rangelands, forests, drylands, freshwater, coastal and marine systems, and mountain ecosystems, as well as some urban areas, across North America with the help of partners around the world.
