Demeter - A Land Use and Land Cover Change Disaggregation Model

Demeter provides a flexible and repeatable methodology to connect models at varying scales to account for land surface changes

Demeter disaggregates regional allocation and future projections of land into multiple resolutions of gridded land use and land cover representations to advance the science of multi-sector, multi-scale research.

The Science

Land use and land cover have a strong influence on the evolution of the Earth system, but tools for downscaling and propagating these changes across different modeling platforms are limited.

Demeter, an open-source model developed by the U.S. Department of Energy's Pacific Northwest National Laboratory, is designed to translate regional projections of future land use from integrated human-Earth system models into high-resolution representations of time-evolving land cover suitable for input into complex Earth system and global hydrologic models.

The Impact

Demeter provides a flexible and repeatable methodology to connect models that produce or require land use and land cover data at varying scales. Demeter is a well-documented, open-source community model that uses a common scale-independent methodology to advance the science of multi-sector, multi-scale dynamics research.
