Resumo(s)
This study examines the potential of combining decision support approaches to identify
optimal bundles of ecosystem services in a framework characterized by multiple decision-makers.
A forested landscape, Zona de Intervenção Florestal of Paiva and Entre-Douro and Sousa (ZIF_VS)
in Portugal, is used to test and demonstrate this potential. The landscape extends over 14,388 ha,
representing 1976 stands. The property is fragmented into 376 holdings. The overall analysis was
performed in three steps. First, we selected six alternative solutions (A to F) in a Pareto frontier
generated by a multiple-criteria method within a web-based decision support system (SADfLOR)
for subsequent analysis. Next, an aspatial strategic multicriteria decision analysis (MCDA) was
performed with the Criterium DecisionPlus (CDP) component of the Ecosystem Management
Decision Support (EMDS) system to assess the aggregate performance of solutions A to F for the
entire forested landscape with respect to their utility for delivery of ecosystem services. For the CDP
analysis, SADfLOR data inputs were grouped into two sets of primary criteria: Wood Harvested and
Other Ecosystem Services. Finally, a spatial logic-based assessment of solutions A to F for individual
stands of the study area was performed with the NetWeaver component of EMDS. The NetWeaver
model was structurally and computationally equivalent to the CDP model, but the key NetWeaver
metric is a measure of the strength of evidence that solutions for specific stands were optimal for
the unit. We conclude with a discussion of how the combination of decision support approaches
encapsulated in the two systems could be further automated in order to rank several efficient solutions
in a Pareto frontier and generate a consensual solution
