Can environmental economic valuation techniques aid ecological economics and wildlife conservation?

I evaluate the potential usefulness of nonmarket valuation concepts and techniques from environmental economics for improving wildlife conservation. The concepts include distinguishing between on-site recreation use value and off-site passive use or existence values. In addition, I review 3 nonmarket valuation techniques. I illustrate the concepts and use of the technique of contingent valuation with a case study of valuation of increased ecosystem services for a riverine ecosystem. Results suggested that the benefits to households living along the river exceeded the costs of water rental from farmers and conservation easements.
