Ecosystem Portfolio Models
The model evaluates performance of land use plans against
multiple management criteria, incorporating economic, ecological,
and human well-being submodels.
The South Florida Ecosystem Portfolio Model (SFL EPM) is a Geographic Information System-based multi-criteria decision support web tool that evaluates land use plans and proposed land use/land cover (LU/LC) changes in terms of performance criteria related to three dimensions of value: 1) modeled ecological criteria related to ecosystem services, expressed as “ecological value” 2) predicted land market prices and the associated probability of LU/LC conversion, and 3) community quality-of-life indicators. Each of these dimensions is implemented as a sub-model of the EPM that generates “value maps” for a given land use pattern and set of user-elicited preferences, where the value map reflects changes in parcel and landscape attributes. The modeled parcel/landscape attribute changes are related to land use/cover change, including changes in habitat potential and landscape fragmentation, distances to human perceived amenities, community “character”, flooding and hurricane evacuation risks, water quality buffer potential, ecological restoration potential, and other relevant performance criteria. Users can examine the resulting value maps for one or more land use/cover patterns under different weighting schemes, allowing the user to explore how different prioritizations of objectives affects the evaluation process. More broadly, users can also compare ecological value maps, predicted land price maps, maps of community quality-of-life indicators for sets of land use/cover patterns to characterize regional-scale trade-offs between ecological, economic, and social values. By using maps as the means of comparison, local details are retained, while regional patterns emerge.
