Module 4.3 What are the DRIVERS and PRESSURES causing environmental change?
5 Once we have come to understand the specifics of the environmental state, we can then start developing
an integrated story of what is happening to the environment and why. We accomplish that by answering:
“What are the Pressures and Drivers that have caused the change to occur?” Examples of types of
drivers and pressures identified in many global environmental assessment reports, such as UNEP’s
9-12 December, 2013 2005, are provided in Table 6.

4. modification and movement of organisms
The purpose of identifying drivers and pressures is to establish an integrated story of likely causes of the
observed changes in the state of the environment. The story starts with identifying a pressure, which is
readily identifiable as a cause of the environmental change. For example, sewage discharge represents a
pressure causing changes in water quality in Tubli bay. A driver behind this particular pressure could be
rapid population growth and industrial development.
