Q

To ensure that in decision making all the relations/associations that cause trade offs and synergies are well known, to prevent unwanted consequences

Q

What are the important factors to consider when doing any kind of trade-off analysis?

A
  • Differences in the Temporal dimension/ dynamics of ecological functions;
  • Differences in units of different ES;
  • Differences in the spatial extent of the ecological functions;
  • Visual representation of those interactions.

Q

What are the types of trade-off visualisation/quantification tools? And what are the disadvantages of each?

A

-Pear wide tool (only for comparing 2 ES);
-Multivariate analyses:
Principle component analysis (PCA) ( only for when all components are quantitative)
or Multiple Correspondences analyses
( for when components are factors)
But there can be a mic between those two;

Q

What are the integrative tools for trade off analysis?

A

extended CBA and Multicriteria analysis ( those are complementary, the result of one can be used to run the other)
