Evaluation of Environmental Monitoring Strategies

AMBIO: A Journal of the Human Environment, 2003
In environmental monitoring, it is important that the monitoring system should emit early warnings when undesired events occur. These events may be sudden or of a more subtle nature. In the design of such monitoring systems, a proper balance between cost and risk must be achieved.
