Ecosystem Services and the Gulf Disaster

The BP oil spill will degrade critical ecosystem services and their economic benefits for decades to come.

WRI’s Lauretta Burke discusses her work on measuring the economic value of coral reefs in the Dominican Republic and other Caribbean countries.

This policy note provides an overview of the range of actions, policies, and institutions around the globe that address nutrient pollution and eutrophication.

This policy note provides a snapshot of the sources of nutrient pollution and the corresponding socioeconomic drivers that are increasing nutrient levels in our waterways.

Belize’s Reefs and Mangroves Tagged with High Economic Value

Three key services provided by coral reefs and mangroves in Belize are worth an estimated US$395 million to US$559 million per year, according to a report released today by the World Resources Institute and the World Wildlife Fund.

EPA Partners With WRI to Heighten Awareness of Ecosystem Services

The World Resources Institute (WRI) and the U.S. Environmental Protection Agency (EPA) today announced a collaboration to deliver improved science and practical tools to help companies and governments protect ecosystems and address climate change.

Caribbean Sub-Regions

Nine Caribbean sub-regions—Bahamian, Bermuda, Eastern Caribbean, Florida, Greater Antilles, Gulf of Mexico, Southern Caribbean, Southwestern Caribbean, and Western Caribbean.

When the four threats – coastal development, sedimentation, marine-based pollution, and overfishing – are integrated into the Reefs at Risk Threat Index, nearly two-thirds of the region’s coral reef

Coral Disease Observations

Most reported observations of coral disease worldwide have been in the Caribbean.

Observations of coral bleaching in the Caribbean are widespread. Of the over 500 observations in recent decades, 24 were during the 1980s, over 350 during the 1990s, and over 100 since 2000.

Threats to coral reefs from overfishing were evaluated based on coastal population density adjusted by the shelf area (up to 30 m depth) within 30 km of the reef.

Threats to coral reefs from marine-based sources were evaluated based on distance to ports (stratified by size), intensity of cruise ship visitation, and distance to oil and gas infrastructure, proces

When corals undergo certain kinds of stress, much of the zooxanthellae – the symbiotic algae that provide coral polyps with nutrients – are expelled from the coral tissue.
