Sound Health 2008 Environmental Indicators: A report on the Status and Trends in the Health of Long Island Sound
 

What are Environmental Indicators? What is DPSIR?
Environmental indicators provide quantitative information on ecological resources, including the state of specific environmental conditions, good or bad. There are several methods to categorize and analyze types of indicators. For Sound Health, each indicator will be classified as a Driver, Pressure, State, Impact, or Response under the “DPSIR” framework.

Definitions of DPSIR Indicator Types
(Source: European Water Framework Directive)

Driver—an anthropogenic activity that may have an environmental effect (e.g. agriculture, industry); also driving force.

Pressure—the direct effect of the driver (e.g. an effect that causes a change in flow or a change in the water chemistry of surface and groundwater bodies.

State—The condition of the water body resulting from both natural and anthropogenic factors (i.e. physical, chemical, and biological characteristics).

Impact—The environmental effect of a human or ecological pressure (e.g. fish killed, ecosystem modified).

Response—The human response (e.g. habitat restoration, pollution reduction) to a pressure or state.
