Table 3: Transition rules for the two scenarios to create alternative futures
Land use type in scenario
“Climate mitigation”
The simulation of land use changes in each scenario followed the transition rules listed in
table 3. Plots of land were selected that fulfilled the land use type criterion, or the
combination of land use type and soils criteria. The attributes of the selected plots were
subsequently changed to represent the land use type of the respective scenario.
3.2.4 Assessment and report of impacts of the two scenarios on biodiversity
To assess the impacts of the two scenarios, the respective alternative futures were used as
input for the developed models in the ArcGIS model builder environment. The resulting
evaluation maps were color coded for the respective importance of each polygon on the 1 to
five scale. Furthermore, the respective distribution of areas for each level of importance
was summarized in a table, and illustrated in a bar chart for comparison (figure 2).
