Abstract

This study aims to estimate the value of environmental services that could be generated by seawater flowing in the Geumgang Estuary by using meta-regression for benefit transfer. The environmental services that can be generated by seawater flowing are assumed to be improved water quality, increased biodiversity, and enhanced water-friendly effect. The analysis was conducted using 122 data from 28 studies from EVIS. The results show that households in the neighborhood where seawater is distributed are willing to pay about KRW 46,918, KRW 7,752, and KRW 7,859 per year for improved water quality, increased biodiversity, and enhanced water-friendly, respectively. The WTP of the national households other than neighboring households was found to be KRW 19,401, KRW 3,206, and KRW 3,250 for the three environmental services, respectively. The WTP for water quality improvement is higher than that for biodiversity increase and water-friendly effect increase, which may be due to the fact that water quality improvement is an environmental service that is close to the use value. In addition, neighboring households have a higher WTP than national households because neighboring households are more likely to evaluate the benefits of seawater flowing as a use value, while national households are more likely to evaluate it as a non-use value.
