Environmental Monitoring; A Case Of Learning Through Evaluation?

The aim of environmental monitoring programs is to provide information useful in enforcing existing environmental statutes and helping to detect and prevent future problems. Despite the considerable number of monitoring programs being conducted, information on the quality of the nation's environment remains poor and of little use in supporting environmental policymaking. This paper examines the role evaluation has played in developing an effective nationwide environmental monitoring system. Background information on environmental monitoring programs is provided, followed by a discussion of the evaluations of past programs and recommendations made for improvement. One program in particular, the “Status and Trends” program administered by the National Oceanic and ATmospheric Administration, is examined to explore whether environmental monitoring demonstrates a case of learning through evaluation. “Status and Trends” is based on the experience gained during several of the previous monitoring programs and incorporates many of the recommendations spawned from earlier environmental programs. Whether the program demonstrates a case of learning through evaluation will depend on the ability of the program to evolve as we learn more about environmental quality and out ability to measure it.
