Geosciences and Environmental Change Science Center
The National Land Change Assessment (NLCA) is a research effort that examines the causes, trends, and implications of United States land change. The project takes a comprehensive approach towards understanding land change by systematically examining land conversion and management across a full range of land use and land cover types and climate and ecological settings. Land change is a key driver of environmental change and has important implications related to climate variability and change, biodiversity, natural resources, and ecosystem services.
Historical and recent land transformations are examined using an innovative multi-scale ecoregion framework . The approach employs a variety of spatial analysis approaches to provide an understanding of the geographically- and temporally-variable processes of land change, focusing on the interactions between humans and their environment. A goal of the project is to provide a scientific basis for land management and policy decisions related to issues of sustainability and resilience.
How are the long-term trends, land change transitions, and historical legacies of land use change affecting social-environmental systems and sustainability? This research examines the spatial-temporal dynamics and implications of US land change within the context of global environmental change.
