Action plan launched over 'unprecedented' coral reefs damage

Scientists are moving ahead with plans for action to save the world's coral reefs, in the face of "unprecedented" damage.

A call to arms from three Pacific island nations whose reefs are in the crosshairs of the largest and longest-lasting coral bleaching event in recorded history has been presented at the International Coral Reef Symposium (ICRS) in Honolulu, Hawaii.

The heads of state from Palau, Micronesia and the Marshall Islands attended the conference and will provide a plan to help save their ailing coral reefs, which are major contributors to their local economies and the daily sustenance of their people.

The call to action, signed by the three presidents, asked for better collaboration between the scientific community and local governments, saying there needs to be more funding and a strengthened commitment to protecting the reefs.

The letter said: "If our coral reefs are further degraded, then our reef-dependent communities will suffer and be displaced."

They also called for more integration of "traditional knowledge, customary practices and scientific research" in building a comprehensive coral reef policy.

"We are not ready to write the obituary for coral reefs," James Cook University professor Terry Hughes, president of the ARC Centre of Excellence for Coral Reef Studies in Australia, said.

In response to the letter, the scientific community at the conference said: "We pledge to take up the 13th ICRS Leaders' Call to Action, and will work together with national leaders of the Federated States of Micronesia, the Republic of Palau, the Republic of the Marshall Islands, and the world to curb the continued loss of coral reefs."

Bleaching is a process whereby corals, stressed by hot ocean waters and other environmental changes, lose their colour as the symbiotic algae that lives within them is released.

Severe or concurrent years of bleaching can kill coral reefs, as has been documented over the past two years in oceans around the world. Scientists expect a third year of bleaching to last through to the end of 2016.

In the northern third of the Great Barrier Reef, close to half of the corals have died in the past three months, said Prof Hughes, who focuses his research there.

The area of the reef that suffered most is extremely remote, he said, with no pollution, very little fishing pressure and no coastal development.

"That's an absolute catastrophe," Prof Hughes said. "There's nowhere to hide from climate change."

But the panel of scientists emphasised the progress they have made over the past 30 years and stressed that good research and management programs for coral reefs are available.

The scientists said they just need the proper funding and political will to enact them.

The researchers focused on the economic and social benefits coral reefs contribute to communities across the globe, saying the critical habitats generate trillions of dollars annually but conservation efforts are not proportionately or adequately funded.

In the United States, the budget for the federal coral reef conservation programme is set at about 27 million (£19.4 million) a year, said Bob Richmond, director of the University of Hawaii's Kewalo Marine Laboratory and convener of this year's ICRS.

In Hawaii, he said, the reefs are valued at 34 billion dollars (£24 billion), and the return to the state's economy is about 360 million dollars (£258 million) annually - meaning the entire nation's budget for coral reef conservation is less than 10% of the annual return in that one state alone.

Florida, Texas, Puerto Rico, the Virgin Islands, Guam, American Samoa and the Northern Mariana Islands also have ailing reefs under the budget.

The Coral Reef Conservation Act of 2000, which aimed to protect coral reefs and create schemes to manage their conservation, has been plagued by political resistance and a severe lack of funding, Mr Richmond said.
