2.1 SCENARIO CONDITIONS
The CLUE model has a number of parameters that need to be specified before a
simulation can be made. The setting of these parameters is dependent on the
assumptions made for a particular scenario. In this exercise we will explore 4 different
scenario conditions:
Land requirements
Spatial policies (area restrictions)
Conversion elasticity
Land use conversion sequences
Different scenarios allow the comparison of different possible developments and give
insight in the functioning of the model. Such analysis is most easy by visual comparison
or through the calculation of the differences between the two scenarios in a GIS.
Assignment for exercise 2.1 to 2.5.
First run the model with the baseline scenario: use the original settings of the ‘main
parameters’ and select ‘region_nopark’ and ‘demand.in1’. Import the results (e.g. for the
start and end of the simulation, year 0 and year 14) and run the model again with
alternative the settings of the exercises 2.2 to 2.5. Compare the results in ArcView. Try
to relate the observed differences to the changes made in model settings.
