Land surfaces are disaggregated in the following categories:
- The surfaces dedicated to Agricultural activities (crops, meadows, pastures). They evolve with an annual trend using population and agricultural productivity (exogenous); the growth decreases when land use is close to saturation).
- The surface of forests evolves to account for the expansion of the agriculture surface.
- Urban areas evolve with an annual trend using urban population and GDP growth.
- Inland water and desert areas evolve with exogenous trends.
- Finally grassland surface (grasslands, shrublands, savannas, natural vegetation mosaic) is the difference between the total country / region area and all other surfaces.
Energy biomass is produced from the following surfaces:
- 1st generation biofuels: agricultural area, grassland
- other uses: forest area (for forest residues), grassland (for short rotation crops)
Yields evolve over time, based on historical evolution.
GHG emissions from agriculture and land-use are derived from a soft linkage with the GLOBIOM model.
