Ten-year evaluation of the Great East Japan Earthquake through citizen participation-type research, aiming for coastal ecosystem conservation for a sustainable society

Research grant

Project Description

How will the ecosystem adapt to and recover from disturbance from a tsunami? To evaluate this correctly, it is necessary to analyze 10-year survey data. Therefore, since the year of the Great East Japan Earthquake, citizen participation-type biological monitoring research in tidelands has been carried out. This year monitoring will continue, and is planned to continue until the tenth year since occurrence, and the impact of subsequent disaster infrastructure developments, and the impact of the earthquake on the ecosystem, will be revealed. Also, information on the biological interaction of tideland ecosystems will be gathered from field experiments and surveys. Based on these results, sustainable coastal ecosystem conservation methods will be proposed. [No. R17-1011]
