Advanced description of the allocation procedure of the new Dyna-CLUE 2
version
The model is an adapted version of the CLUE-s model (Castella and Verburg, 2007;
Verburg et al., 2003) which is based on the spatial allocation of demands for different
land use types to individual grid cells. The version implemented (Dynamic Conversion of
Land Use and its Effects model: Dyna-CLUE version 2.0) combines the top-down
allocation of land use change to grid cells with a bottom-up determination of conversions
for specific land use transitions. The analysis starts by grouping the land use types into
two groups: those that are driven by demand at the regional level and those for which no
aggregate demand at the regional level can be determined. In many applications, the
demands can be specified for urban and agricultural land uses (including production
forest) while no specific demand can be determined for the (semi-) natural land cover.
The land cover types for which no demand can be specified are grouped into one, new,
category for which the aggregate change in area results from the dynamics of the other
land use types, i.e., the overall change in area of this new category corresponds to the
net change in the demand-driven land use types (Figure 1).
