5 EXERCISE

Understanding the Issue

In groups of 4-5, carry out the following tasks:
9-12 December, 2013 ? ? and 6 and put this into the first row of the table provided.
Select the drivers – pressures – state – impact chain from your exercises in sections 5
?

In the second row, identify an indicator and approximate trend line that, in your best
judgment, describes reality, or use actual data if available.

Note major changes in the indicator trend over time.

Description

Indicator and trend

Time: 20 minutes.

Identifying and explaining key trends in environmental state indicators is a central part of
creating a baseline understanding for policy analysis. Environmental state may be influenced
by anthropogenic drivers and pressures and these typically have some underlying policies.
For instance, over-fishing may be driven by the availability of easy credit for fishing fleet
development and no restrictions on potentially damaging fishing practices. However, state
variables are also affected by natural causes, and phenomena such as El Ni?o events can
contribute to fish population dynamics in positive and negative ways.

Such an analysis can also be conducted to better understand pressures and drivers. The case
example presented in section 4.4.2, illustrates this.
