Summary

The purpose of this study is to develop a model to determine the appropriate economic valuation of the full effects of pollution on aquatic ecosystems. The study determines the economic value of ecological goods and services by identifying the ways in which aquatic ecosystems are valuable to mankind, characterizing these benefits in ecological terms, and assessing the economic value. Alternative approaches to valuation such as suite of indicator variables (SIV) and other ecological scoring methods are also reviewed. A model is developed that takes into account recovery lags, irreversibilities, and uncertainty. These are important characteristics to ecosystems. Methods of benefit estimation for three uses: the environment as input, as a final good, and for non-use benefits, are discussed and directions for further work are presented.
