gcamland is an open source R package that was built to allocate land across a variety of types based on changes in agricultural yield and commodity price. The land allocation algorithm is based on the one included in the Global Change Assessment Model (GCAM). gcamland includes the ability to run in a historical mode, enabling model validation and parameter estimation, or in a future mode, simulating changes in land use/land cover in the future. For both modes, gcamland can run a single simulation or a large ensemble of simulations with different parameters. When ensembles are generated in the historical mode, gcamland calculates the likelihood of a given parameter set by comparing to observational data. gcamland is publicly available via GitHub and has can be adjusted to represent alternative scenarios or configured to different regions and land types.
