The region-specific regression models are used in IMAGE to calculate the suitability of land areas in annual time-steps. As well as the suitability assessment, some additional rules are applied. The suitability of strictly protected areas is substantially reduced, or these areas are regarded as entirely unsuitable based on scenario assumptions. Optionally, a small random factor can be included to account for inherent uncertainty and non-deterministic behaviour of land-use change processes, allowing the emergence of new agricultural patches. Agricultural land is expanded according to the final suitability ranking. Extensive pastures located in areas where the natural vegetation is grassland are assumed to be rather constant over time, and thus do not expand and are only abandoned as a result of climate change. | The region-specific regression models are used in IMAGE to calculate the suitability of land areas in annual time-steps.

Land use in IMAGE is modelled using dominant land use types per grid cell on a 5 x 5 minute resolution. In reality, land use is more heterogeneous. For some applications, dominant land use on 5 x 5 minute resolution, or the derived proportional land use on a 30 x 30 minute resolution may be sufficient. However, many applications require higher resolution and additional data, such as studies on biodiversity and agricultural intensification ([[Verburg et al., | Land use in IMAGE is modelled using dominant land use types per grid cell on a 5 x 5 minute resolution.
