Outline of Final Research Achievements

Conducting international joint studies in Indonesia and Philippines, where blue carbon in coastal ecosystems has been rapidly decreasing due to degradation of the ecosystem, we could clarify carbon dynamics and associated ecosystem characteristics and material cycles in blue carbon ecosystems consisting of mangroves, seagrass and others in the joint study areas. We conducted also the development of various simulation models to analyze and predict blue carbon dynamics in an integrated atmosphere-land-ocean system, and remote sensing analyses. Based on all these results, we succeeded in developing a model system which would enable the future prediction of the changes in the carbon dynamics and the decrease in the blue carbon stock under global warming and other anthropogenic impacts.
