What A Million Corals In 2,500 Reefs Tell Us About Saving Them

What A Million Corals In 2,500 Reefs Tell Us About Saving Them

Researchers examined more than a million individual corals across 44 countries for a new study on how to save coral reefs in the Indian and Pacific Oceans.

When Joleah Lamb strapped on a scuba tank and plunged into the ocean over a decade ago, it was the first of many expeditions to examine the effects of climate change and other human-produced factors on coral.

Now, 13 years after that foray, she has contributed one of the largest amounts of data to a landmark study on coral reefs.

Lamb, an assistant professor of ecology & evolutionary biology at the School of Biological Sciences at the University of California, Irvine, is among more than 80 marine researchers worldwide who produced the report, which appears in Nature Ecology and Evolution.

The research encompassed over 2,500 reefs. Lamb provided its fourth-largest dataset, containing details on more than a million individual corals. Gathering the information required painstaking visual inspection, with Lamb and colleagues swimming underwater for as much as six hours each day. Armed with special measuring tapes, waterproof paper, and pencils, they recorded information on each coral, meticulously identifying the size and health of more than 300 unique species.

Observations of bleaching, a visible indication water is too warm, were key to this study. When temperatures rise, corals expel algae they normally depend on for energy. The depletion robs the corals of their color and turns them white. It also eventually starves them.

“There are efforts to use drones or satellites to collect this information, but you cannot get the high resolution needed to assess the vital complex architecture of reefs unless you are in the water,” says Lamb.

The scientists involved in the report say it’s not too late to save reefs if three strategies are immediately enacted in the Indo-Pacific. One is protecting from human impact those that are functioning, representing 17% of the reefs studied. Another is helping the 54% that are damaged but have the potential to recover. For 28%, it may be too late for rescue, which suggests some coastal societies will need to transition away from depending on them.

Lamb says Americans should be concerned about the research results. “There are a lot of reefs in our territories, such as Hawaii, American Samoa, and Guam,” she says. “They all face severe impacts from the loss of coral reefs, including on coastal protection, food, and income from tourism. And even if you don’t live close to a reef, carbon emissions contribute to climate change that harms corals worldwide.”

Researchers with the Wildlife Conservation Society, as well as other non-profit organizations and governmental agencies, participated in the study. Support for the study came from the John D. and Catherine T. MacArthur Foundation and the Bloomberg Philanthropies’ Vibrant Oceans Initiative.

A Critical Approach to Climate Change Adaptation: Discourses, Policies and Practices

by Silja Klepp, Libertad Chavez-Rodriguez
9781138056299This edited volume brings together critical research on climate change adaptation discourses, policies, and practices from a multi-disciplinary perspective. Drawing on examples from countries including Colombia, Mexico, Canada, Germany, Russia, Tanzania, Indonesia, and the Pacific Islands, the chapters describe how adaptation measures are interpreted, transformed, and implemented at grassroots level and how these measures are changing or interfering with power relations, legal pluralismm and local (ecological) knowledge. As a whole, the book challenges established perspectives of climate change adaptation by taking into account issues of cultural diversity, environmental justicem and human rights, as well as feminist or intersectional approaches. This innovative approach allows for analyses of the new configurations of knowledge and power that are evolving in the name of climate change adaptation. Available On Amazon
