Interventions to help coral reefs under global change-A complex decision challenge

Area of Science:

• Marine Biology
• Climate Science
• Conservation Science

Background:

• Coral reefs are critically threatened by global heat waves and climate change.
• Conventional management and climate change mitigation alone are insufficient for reef survival.
• Recent bleaching events necessitate a reevaluation of reef management strategies.

Purpose of the Study:

• To address the inadequacy of current strategies in sustaining coral reefs under climate change.
• To propose a comprehensive approach integrating mitigation, conventional management, and novel interventions.
• To emphasize the urgent need for research, development, and safe trialing of new reef management tools.

Main Methods:

• Review of current climate change impacts on coral reefs.
• Analysis of existing and potential management and adaptation strategies.
• Discussion of challenges, opportunities, risks, and uncertainties associated with new interventions.
• Proposal of a conceptual model for reef management decision-making.

Main Results:

• Current management and mitigation efforts are insufficient to combat climate change impacts on coral reefs.
• A portfolio approach including radical interventions (e.g., cooling, assisted evolution) is essential.
• Proactive research, development, and safe trialing of new interventions are urgently required.
• Effective solutions demand coordination across science, management, policy, and society.

Conclusions:

• Coral reef survival necessitates a paradigm shift towards proactive, adaptive management.
• Integrating novel interventions alongside conventional practices is crucial for resilience.
• A coordinated, society-engaged approach is vital to navigate the complexities of reef conservation in a changing climate.
