Outline of Final Research Achievements

The purpose of this study is to implement the results of the research on Non-point source pollution control in the field of environmental economics in order to advance the conservation of wetlands in East Asian waters where Ramsar site is concentrated. In the theoretical study, a tournament approach is used to design a policy that could control Non-point source pollution independently of the number of polluters. In the research study, the coordination among important wetlands is classified into unregistered wetlands, registered wetlands, unregistered wetlands and registered wetlands, and the effects of changes in the order of registration and number of registered wetlands on the benefits of registered wetlands are organized.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は，本研究が新たに提案するトーナメント・アプローチによって，従来研究ではできなかった，汚染主体の数が少ない場合でも，多い場合でも面源汚染を適切に制御することを可能にしたことである。また，社会的意義は，面源汚染制御政策の各地域への実装によって，これまでのようにただ技術的解決だけに頼るのではなく，経済的インセンティヴに基づく政策を合わせることで，さらに汚染水準の改善を進めることが可能となることである。
