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.

                  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.
