2
DPSIR model

• A causal framework for describing interactions
  between society and the environment.

3
Driving forces

• Underlying factors that influence development
  such as population growth, energy consumption,
  economic growth and industrial production.
• Driving forces may be of economic, judicial,
  social, political or technological nature.
• CASE ACID RAIN Economic growth gt Energy
  consumption.

4
Pressures

• Human activities that influence the natural
  environment and changes its state.
• Examples Emissions of polluting substances or
  resource exploitation such as land use.
• CASE ACID RAIN Sulphur and nitrogen emissions to
  air.

5
State

• Current state of the environment.
• CASE ACID RAIN Acidification of lakes and rivers.

6
Impact

• Effect of changes on both environment and
  society.
• CASE ACID RAIN 18 lost salmon stocks, 12
  endangered gt 3 billion NOK lost every year.

7
Response

• Society can make political, economic or
  behavioural changes as a reaction to changes in
  the environment.
• Responses can be aimed at any of the links in the
  causal chain (DPSI).
• CASE ACID RAIN Limiting emissions (aimed at P),
  liming rivers (aimed at S).

8
Case Ground water depletion

• Driving forces Population growth,
  subsidies/political agenda gt agricultural growth
• Pressure Ground water extraction, water
  consumption
• State Ground water level
• Impact Increased water salinity gt soil salinity,
  reduced aflaj flows gtloss of cultural
  environments
• Response Producing desalinated water (I),
  raising awareness (P),
