Landscape Change and Impacts
Landscape Change and Impacts
Land Use and Land Cover Change (LULCC) results from both human activities and natural climate and geomorphic processes. Using remotely sensed data, ground-based observations, historical accounts, and other reconstructions, the Ecosystems Land Change Science Program documents long-term patterns of LULCC, determines their consequences, and anticipates impacts of future management changes.

Holocene Hydroclimate of Western North America
The objectives of this project are to reconstruct detailed histories of Holocene hydroclimate and corresponding environmental change from geological archives such as lake sediment, peat, and wood to more fully understand past, ongoing, and future change and its impacts.
Paleohydrology of Desert Wetlands
Springs and wetlands are among the most highly threatened ecosystems on Earth. Although geographically limited, they support more than 20% of all the threatened and endangered species in the United States. Scientists from the U.S. Geological Survey are examining the rock record to determine how springs and wetlands responded to abrupt climate change during prehistoric times and the recent geologic...
Patterns in the Landscape – Analyses of Cause and Effect
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...
