Development of coral restoration technology for islands

由于全球变暖导致的珊瑚白化，世界各地的珊瑚礁正在迅速退化。珊瑚退化最严重的情况是在礁滩上失去珊瑚。生长在礁滩上的珊瑚受到海浪的侵蚀，岛屿也不会下沉。此外，在热带国家，珊瑚作为珊瑚礁生态系统的主要生产者一直被保存着。利用新开发的炉渣陶瓷珊瑚沉降装置，成功开发了外礁浅滩珊瑚修复技术，并在日本关井潟湖和印度尼西亚布纳肯国家公园开发了珊瑚修复技术。

Coral reefs around the world have been rapidly degrading due to the coral bleaching caused by global warming. The largest critical situation of the degrading corals is to lose corals on the reef flat. Corals growing on the reef flat have been prevented from erosion of coral reef by wave and Islands from sinking. Also, corals have been kept coral reef ecosystem as a primary producer in the tropical countries. We successfully developed coral restoration technology for the shallow reef flat at the outer reef, by newly developed slag-ceramic coral settlement device and developed the coral restoration technology to use it at Sekisei Lagoon, Japan and Bunaken National Park in Indonesia.
