Lecture 7 Trade offs

Question 1

When do interactions between different ecosystem services occur?

Answer 1

Interactions between different ecosystem services occur when multiple services respond to the same driver of change.

Question 2

What is trade off?

Answer 2

Trade off is when the use of one ecosystem service directly decreases the benefits supplied by another

Question 3

What is synergy?

Answer 3

Synergy is when the use of one ecosystem service increases the benefit of another

Question 4

What are ecosystem services bundles

Answer 4

ES bundles are sets of ES that appear togther across space and time

Question 5

Why doing a tradeoff analysis?

Answer 5

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

Question 6

What are the 2 different types of trade offs?

Answer 6

1) Negative correlation between ES

2) conflicting land use or management options

Question 7

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

Answer 7

• 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.

Question 8

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

Answer 8

-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;

Question 9

What are the integrative tools for trade off analysis?

Answer 9

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