Decision makers can use an indicator framework to obtain a better picture of the links between the complexity of factors in the environment—development process that might potentially influence human health. One such indicator framework is an adaptation of the pressure, state, response (PSR) framework developed by the OECD, which in turn is based on earlier work done by the Canadian government.
The PSR framework has been particularly useful in representing the way in which pollution affects the environment, for example by looking at the various pressures exerted on the environment, which affect the state (quality) of the environment and consequently demand a response for dealing with the situation. However, this framework has been criticized for being linear and unidirectional, and various adaptations have been proposed.
