| Outline of Final Research Achievements |
The environmental change and deterioration of coral reefs may have a greater influence on local causes than global warming. Collecting changes in coral reef environments as "effects of global warming" leads to misleading measures to solve problems and solutions. In this research, as an example of the Ryukyu Archipelago where reef coral reefs are formed along the land area , changes in coral reef environments are tracked over the past decades with the seagrass seaweed bed as an indicator and the coral reef environment in Okinawa I tried to clarify the change.
Changes in coral reefs and coasts were extracted using satellite images, aerial photographs, UAV (drone), topographical maps. Significant changes were extracted in shallow water areas and coastlines of coral reef centered on the main island of Okinawa. Many were inferred that artificial activities were affected.
