Management that takes evolution and adaptation into account can help rescue coral reefs from the effects of climate change, according to a new study.

Importantly, the results show that by making smart decisions to protect reefs today, conservation managers can generate the conditions that can help corals adapt to rising temperatures.

“It is well documented that climate change is causing corals to die off at an unprecedented rate, but our study provides tools that offer promise for their survival,” says coauthor Madhavi Colton, program director at the nonprofit Coral Reef Alliance. “Our results show that when evolution is enabled, conservation efforts can help corals adapt to rising temperatures.”

Saving coral reefs from climate change

Contrary to approaches that are popular today, such as focusing protection on reefs in cooler water, the study shows that protecting diverse reef habitat types across a spectrum of ocean conditions is key to helping corals adapt to climate change.

“We found that a diversity of reef types provides the variety that evolution depends on,” says coauthor Malin Pinsky, an associate professor at Rutgers University. “Hot sites are important sources of heat-tolerant corals, while cold sites and those in between can become important future habitats. Together, a diversity of reef types act as stepping stones that give corals the best chance for adapting and moving as climate changes.”

Key to successful evolution is management that improves local conditions for reefs by effectively reducing local stressors, such as overfishing and water pollution. However, the authors caution that not all management strategies are created equal.

“We used mathematical models to test the effects of management choices on coral reef outlooks,” says lead author Tim Walsworth, a postdoctoral researcher at the School of Aquatic and Fishery Sciences at the University of Washington.

“We found that corals in well-managed areas act as a source of baby corals in the future, essentially rescuing reefs after the climate stabilizes. Without both evolution and management, the corals in our model were unable to survive rising temperatures.”

Time to act

Coral reefs are one of the most diverse ecosystems on the planet and support the livelihoods of over 500 million people. Globally, they are estimated to be worth $375 billion per year.

The study shows that managing reefs to facilitate evolution today and in the future can enhance their prospects for long-term survival. This means creating managed area networks that contain a diversity of coral types and habitats and effectively reduce local stressors.

“This study shows that we know enough of the science to act—and with the effects of climate change only increasing, we have little time to waste,” Colton says.

The study appears in Nature Climate Change.

The study is the result of a collaborative research program Colton and Michael Webster of the Coral Reef Alliance launched. Additional coauthors and project collaborators came from the University of Washington, Stanford University, and the University of Queensland. Funding for the research came from the Gordon and Betty Moore Foundation.

Climate Adaptation Finance and Investment in California

by Jesse M. Keenan
0367026074This book serves as a guide for local governments and private enterprises as they navigate the unchartered waters of investing in climate change adaptation and resilience. This book serves not only as a resource guide for identifying potential funding sources but also as a roadmap for asset management and public finance processes. It highlights practical synergies between funding mechanisms, as well as the conflicts that may arise between varying interests and strategies. While the main focus of this work is on the State of California, this book offers broader insights for how states, local governments and private enterprises can take those critical first steps in investing in society’s collective adaptation to climate change.

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
