Working to Protect Reefs at Risk

Seventy-five percent of the world’s coral reefs are threatened by human activities, according to Reefs at Risk Revisited, a new global analysis led by Lauretta Burke of the World Resources Institute and more than 25 partner institutions including Conservation International (CI). Nearly a third of the world’s coral reefs have become more threatened since the original Reefs at Risk report was released more than 10 years ago. The new analysis incorporates knowledge about threats to corals reefs from climate change, in addition to documenting increasing impacts like those from overfishing and run-off.

It is troubling to me to see the drastic increase of the impacts on these extremely valuable resources over the last 10 years. This latest report is an urgent warning that we can lose many of the world’s coral reefs within our lifetimes, and highlights the critical linkage between healthy ecosystems and human well-being. Reefs at Risk Revisited highlights this linkage by documenting the degree to which coastal people depend on coral reef resources.

Coral reefs provide several critical benefits, known as ecosystem services, to more than 275 million people who live within 30 kilometers (18 miles) of a coral reef. These benefits range from protecting coastlines from storms and sustaining vital fisheries to bringing in millions of dollars a year from tourism. If coral reefs continue to decline, coastal communities could see major losses in their livelihoods, particularly in several countries where CI works, such as the Philippines, Comoros, Vanuatu, Tanzania, Kiribati, Fiji and Indonesia.

Many countries have made important steps in their efforts to protect coral reefs. For example, CI has worked with the government of Kiribati to create the world’s largest World Heritage Site, the Phoenix Islands Protected Area. However, sustainable management of coral reefs remains a struggle because regulations are not always enforced. Reefs at Risk Revisited found that only 6 percent of the coral reefs currently protected in marine protected areas (MPAs) are considered to be effectively managed.

From my own research, I know that MPAs can help to stop coral decline and that the benefits of protection increase over time. Work from many other scientists also has shown that sustainable management of coral reefs can help ensure the continued delivery of ecosystem services that hundreds of millions of people rely on. We strongly encourage local and global policymakers to take these factors into consideration — and take action now to preserve coral reefs.

    After many years of working in the marine industry I retired, and expected to spend lots of time under the mango tree. It was not to be. Using my limited skill set I took on the mission to provide free logistical support to organizations with educational, scientific, environmental, and medical interests, operating in remote areas of the Western Pacific and Philippine islands. Using a little boat the “Motor Vessel Carabao” I designed and built for this my mission I have started supplying books to small reading rooms small libraries in island communities, delivering good for organizations, and provide sail cloth to fisherman still using sail power. I have a up coming trip to Banton Island, Bulalacao, Mindoro and then I will be stopping by Apo Reef for a sea turtles survey.
    Can you help me get in touch with your people in the Philippines ?
    I would like to help out where I can

    Interesting point about the enforcement side. I am absolutely certain that state agencies will have to cut back on their personnel costs due to tighter budgets. Here in Hawaii, there are all kinds of threats to our reef – luckily there are a few companies who are taking it upon themselves to stop selling coral jewelry. One of those companies is Na Hoku Jewelers. Thanks again for bringing this important topic to light!
