# Environmental monitoring describes the state of the environment

Sweden has a well-developed system for monitoring the state of the environment, which describes both the current state and changes in the environment. The Swedish EPA coordinates the environmental monitoring. The Swedish time series are in many cases unique in their length.

Environmental monitoring provides a description of the state of the environment, while also identifying environmental changes and potential threats. The work consists of recurring, systematical studies. By comparing the current state to earlier measurements, changes in the environment can be detected.  This also enables the evaluation of the actual effects of environmental protective measures and strategies. Sometimes additional investigations are necessary to conclude if an observed change will lead to problems in the environment.

## National environmental monitoring

Sweden has a well-developed system for monitoring the state of the environment, which describes both the current state and changes in the environment. The Swedish EPA coordinates the environmental monitoring. The Swedish time series are in many cases unique in their length.

## Environmental monitoring program areas

Both the national and the regional monitoring are divided into ten program areas, which in turn consist of several subprograms.
