Governments, businesses, development agencies, and NGOs are increasingly turning to economic valuation as a way to protect coral reefs and mangroves. This process makes the economic case for protection and sustainable use of natural resources by showing the monetary, employment, and infrastructure benefits ecosystems provide—metrics that are easily understood by decision-makers.
But not all economic valuations are created equal. WRI's new guidebook shows how NGOs and other stakeholders can conduct economic valuations in ways that lead to real change on the ground.
Roughly 75 percent of the Caribbean's coral reefs are threatened--with more than 30 percent ranking in the "high" or "very high" threat category. But one reef system in Cuba, Jardines de la Reina (the "Gardens of the Queen"), offers great lessons—and hope—for effective coral reef management.
Governments, corporations, and development agencies are increasingly interested in putting a dollar value on ecosystems in order to balance conservation and development needs, a concept known as “economic valuation.” For example, St. Maarten’s government recently established the country’s first marine national park after a local organization found that the area’s coastal ecosystems contribute $58 million per year through tourism and fisheries. Belize enacted a host of new fishing regulations based on a WRI valuation, which found that coral reef- and mangrove-associated tourism contributes $150 million-$196 million per year to the country’s economy. And in Bonaire, park managers used economic valuation to justify the Bonaire Marine Park’s establishment of user fees—making it one of the few self-financed marine parks in the Caribbean.
These stories show that economic valuation can indeed lead to better coastal policy, conserving these ecosystems and securing their important economic contributions. However, according to new WRI research, these cases tend to be the exception in the Caribbean.
Economic Valuation and Coastal Policy in the Caribbean
In the Caribbean, there is keen interest in economic valuation of coastal ecosystems to inform policy and improve natural resource management. But while the literature on the value of coral reefs and mangroves in the Caribbean continues to grow, these ecosystems continue to decline.
WRI and the Marine Ecosystem Services Partnership (MESP) took a closer look at the impact of previous economic valuation studies in the Caribbean. Out of more than 200 studies of the economic value of the Caribbean’s marine ecosystem goods and services, we were only able to identify 13 that actually influenced marine and coastal management policies, such as those in Bonaire, St. Maarten, and Belize.
WRI co-hosted a dinner last week to honor Indonesia’s President Susilo Bambang Yudhoyono for advancing sustainability, especially in the Coral Triangle. The event took place at the Mandarin Oriental Hotel in New York City, where more than 300 guests from government, business, and the non-profit sector gathered to recognize Indonesia’s president.
WRI’s president, Andrew Steer, opened the event by reminding guests that President Yudhoyono is a “different kind of leader.” Earlier in his career, Steer spent eight years in Indonesia, and he’s seen firsthand how the country has approached its economic and environmental challenges.
“We live in perilous times,” Steer said. “We need innovative thinking and we need out-of-the-box thinking. Today, we have a leader who is an out-of-the-box leader.”
The Coral Triangle, an area stretching from southeast Asia to the edge of the western Pacific, is one of the most biologically diverse marine regions on earth. The area holds 30 percent of the world’s coral reefs and 75 percent of all known coral species. The region’s coral reefs provide food and livelihoods to more than 130 million people living within the Coral Triangle, as well to millions more worldwide.
Despite its importance, the Coral Triangle is the most endangered coral region on earth, with 85 percent of its reefs threatened by local activities like overfishing and destructive fishing, coastal development, and pollution. WRI and partners recently released a new report documenting this situation, Reefs at Risk Revisited in the Coral Triangle. The report provides both a region-wide and country-level perspective on the status of and threats to coral reefs off the coasts of Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands, and Timor-Leste. It also calls attention to the vulnerability of coral reefs in the Coral Triangle and factors leading to degradation and loss. The report aims to set priorities for management of reefs in the region.

Ever wonder how coral reefs contribute to the economy and human health? Or how 60 percent of these "rainforests of the sea" came to be so threatened by local activities? Or what, exactly, a coral polyp is? WRI's Reefs at Risk team, along with two renowned ocean advocates, have the answers to these questions and many more in the new video, Coral Reefs: Polyps in Peril.
WRI worked with Céline Cousteau, founder of CauseCentric Productions and granddaughter of ocean explorer, Jacques Cousteau; and Jim Toomey, creator of the Sherman’s Lagoon comic strip, to create the video. Through Cousteau’s narration and Toomey’s colorful fish animations, viewers can learn about the vital role reefs play in the health of the planet and important economies, the threats these coastal and marine ecosystems face, and how people can help save invaluable corals.
Coral reefs are beautiful, diverse, productive ecosystems. Many people love to marvel at these rainforests of the sea, but how much does the average person actually know about them? For example, how many people know whether a coral is a rock, a plant, or an animal?
This lack of understanding prompted WRI and partners to release a major report last year on threats facing the world’s coral reefs. The 120-page Reefs at Risk Revisited report contains a wealth of information on the world’s reefs, including a lengthy answer to the question, “What is a coral reef?” There was just one problem: Most people don’t read 120-page reports, so we needed to get the story of coral reefs out to a wider audience.
With more than 75 percent of the world’s coral species and twice the number of reef fish found anywhere else in the world, the Coral Triangle is the center of the world’s marine biodiversity. Stretching from central Southeast Asia to the edge of the western Pacific, 130 million people in the Coral Triangle region depend on marine resources for food and livelihoods. In this way, the region’s coral reefs and associated fisheries are vital to people and national economies, but they’re also severely threatened by overexploitation.
Recognizing the critical role that coral reefs play in people’s lives and the regional economy, the governments of the six countries that make up the Coral Triangle—Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands, and Timor-Leste—came together in 2009 to form the largest marine governance initiative in the world, the Coral Triangle Initiative on Coral Reefs, Fisheries and Food Security (CTI-CFF). Their common goal is to manage their valuable marine resources so that they can continue to provide benefits to people in the future.
Reefs at Risk Revisited in the Coral Triangle
In support of this ongoing initiative, the World Resources Institute and the USAID-funded Coral Triangle Support Partnership have just released a new report, Reefs at Risk Revisited in the Coral Triangle. The report provides both a region-wide and country-level perspective on the risks to reef ecosystems.

Since 1998, WRI has been using GIS (Geographic Information System) models to develop map-based assessments of threats to the world’s coral reefs. Reefs at Risk Revisited, released in February 2011, is the latest assessment in the series and is based on a nearly three-year study that produced the most highly-detailed global maps of coral reef threats to date. The study analyzed and mapped threats to coral reefs from local human activities such as coastal development, unsustainable fishing, and marine and land-based pollution, as well as climate-related threats caused by increasing levels of greenhouse gases in the atmosphere.
