Valuing Ecosystem Services Provided by Lakes: Insights from a Meta-Analysis∗
نویسندگان
چکیده
The values of ecosystem services provided by lakes and reservoirs are examined through a meta-analysis on an expanded worldwide database. The study assesses the socio-economic values attributable to the hydrological, biogeochemical and ecological functions provided by lakes and reservoirs (either natural or artificial). Based on the most extensive global database of non-market and market valuations of ecosystem services provided by artificial and natural lakes, we provide an estimation of the average value of a lake per household (84 USD$2010 per respondent and per year) and we offer some insights on how people value eleven different lake ecosystem services. A particular a high valuation is found for lake amenities whereas a low value is documented for the spiritual or symbolic appreciation of the lake. An interesting result is the fact that some interactions between ecosystem services appear to be significant for explaining lake values. This reflects some tradeoffs, synergies and antagonisms between ecosystem services. As a result, the value for a specific lake ecosystem service is shown to depend upon other ecosystem services provided by this lake. Keywords: Meta-Analysis, Lake, Ecosystem services, Environmental Valuation
