This study presents the first meta-analysis on the economic value of ecosystem services delivered by lakes. A
worldwide data set of 699 observations drawn from 133 studies combines information reported in primary
studies with geospatial data. The meta-analysis explores antagonisms and synergies between ecosystem
services. This is the first meta-analysis to incorporate simultaneously external geospatial data and ecosystem
service interactions. We first show that it is possible to reliably predict the value of ecosystem services
provided by lakes based on their physical and geographic characteristics. Second, we demonstrate that interactions
between ecosystem services appear to be significant for explaining lake ecosystem service values.
Third, we provide an estimation of the average value of ecosystem services provided by lakes: between
106 and 140 USD$2010 per respondent per year for non-hedonic price studies and between 169 and 403
USD$2010 per property per year for hedonic price studies.
