An economic and ecological consideration of commercial coral transplantation to restore the marine ecosystem in Okinawa, Japan

Primary Country: Japan
Ecosystem: coral reef
Sample Value Estimates:
(a) tourism contributed roughly US$6.6 billion to the Okinawa economy in 2009, including the ripple effect, according to Okinawa prefecture. (b) No data on the exact economic contribution of coral reef-based tourism in Okinawa exists, but according to the Japanese Ministry of the Environment, the average ratio of coral reef based tourists in Okinawa between 2003 and 2007 was as high as 43.4%. (c) Assuming the price of transplanting an artificially produced coral transplant, or APT, is US$35 and the recurring profit margin in Japan is roughly 4%, the full cost of transplantation would be roughly US$33.6 per APT. All part of the cost is shouldered by the tourist divers themselves. (d) the price of transplanting a sexually propagated transplant, or SPT, that is produced from coral embryos, ranges from US$24 to $29, but the cost of producing SPT, is estimated to be 13.6-17.9 times as high as that of an APT.

Addtional Notes

 

SPTs cause no damage to the natural colonies and their genetic diversity is much higher. Despite these ecological merits, higher prices would lead to a reduction in the transplants purchased by tourist divers and the firms conducting Corporate Social Responsibility, except by those with high environmental awareness.
