Outline of Final Research Achievements

In this study, we estimated the effects of forest maintenance implemented under ecosystem service payment policies using various models. We developed a method to present the estimated effects to payers and investigate their needs for various ecosystem services. Using this method, we conducted a survey in the Korikawa basin of Omura City, Nagasaki Prefecture. On the premise that payers' needs were expressed in accordance with the actual policy situation, the following knowledge contributing to policy improvement was obtained. Compared to the results of surveys that local governments have conducted to evaluate forest and environmental taxes, it is believed that this will enable a clearer understanding of payers' support for the policy. It became clear which of the various ways to participate in policy to meet one's own ecosystem service needs has the highest motivation to participate.
