KAUST researchers collaborated with international scientists to propose a nature-based adaptive approach for coral restoration, published in Nature Reviews in Earth & Environment. The review emphasizes enhancing specific components of the coral holobiont to maximize the natural adaptive capacity of corals to survive climate change. It advocates for customized protection approaches based on the reef's degradation, location, and traits. Why it matters: This research offers a critical roadmap for preserving coral reefs, which are vital ecosystems threatened by climate change, by leveraging the corals' natural adaptive mechanisms.
KAUST researchers are using 3D printing with a novel calcium carbonate ink to create coral support structures that accelerate coral restoration. Their approach, named 3D CoraPrint, involves printing coral microfragments onto the structure, offering a head start for reef recovery. Two methods were developed: printing a mold for reproduction and direct printing for customization. Why it matters: This eco-friendly technique provides a potentially scalable solution to combat coral reef degradation, leveraging advanced materials and fabrication for ecological conservation in the region and beyond.
KAUST, in partnership with NEOM, is launching the KAUST Reefscape Restoration Initiative at Shushah Island in the Red Sea. The project will restore approximately 100 hectares of reefscape by growing and planting hundreds of thousands of corals. It will also establish a research and ecotourism center. Why it matters: This initiative demonstrates Saudi Arabia's commitment to preserving coral reefs using advanced research and technology, which could have significant implications for marine ecosystem conservation in the region and globally.
The KAUST Reefscape Restoration Initiative (KRRI) observed the first-ever mass synchronized coral spawning in the northern Red Sea at NEOM’s Shushah Island. In March 2023, KRRI launched on-the-reef restoration work at Shushah, propagating nearly 5,000 corals from a dozen species, nearly half of their 2023 annual target. KRRI is testing various coral propagation techniques and nursery designs, aiming to produce half a million corals per year. Why it matters: This initiative is a major step towards coral reef restoration in the Red Sea, aligning with Saudi Arabia's sustainable development goals.
KAUST has launched the KAUST Coral Restoration Initiative (KCRI), the world's largest coral restoration project, with a nursery on the NEOM coast capable of producing 40,000 corals annually. A secondary facility is under construction, designed to nurture 400,000 corals annually and expected to be completed by December 2025. The initiative aligns with Saudi Vision 2030 to bolster marine conservation efforts. Why it matters: This project demonstrates the Kingdom's commitment to environmental sustainability and leverages KAUST's research capabilities to address the critical issue of coral reef degradation, which has far-reaching implications for marine biodiversity and coastal communities.
KAUST scientists have successfully expanded coral spawning through controlled systems, producing approximately two million eggs from six coral species this season to support reef research. Researchers at KAUST's Coastal and Marine Resources (CMR) Core Lab developed facilities that replicate environmental signals to trigger spawning beyond natural seasonal cycles, enabling year-round access to gametes and larvae. This program represents the first successful implementation of shifted phase coral spawning in Saudi Arabia. Why it matters: This breakthrough provides unprecedented opportunities for advancing Red Sea reef restoration and marine science, allowing for continuous study of coral early-life resilience.
KAUST marine biologist Maggie Johnson is studying how to accurately measure environmental conditions to optimize coral restoration, focusing on temperature and light. She highlights the variability in precision and accuracy of commercially available instruments for measuring these parameters. Johnson notes that some instruments fail in the Red Sea's warm temperatures and high salinity, providing incorrect data. Why it matters: Accurate environmental monitoring is crucial for the success of coral reef restoration efforts in the face of climate change, especially in extreme environments like the Red Sea.
KAUST researchers are studying corals in the Red Sea and Arabian Gulf that are more tolerant of high temperatures. They are mating corals from different parts of the world, assuming that the offspring will be more heat-resistant. Using a commercial coral spawning system, the researchers can time coral spawning to cross colonies that would not naturally cross. Why it matters: This research aims to identify genes responsible for temperature resilience and use selective breeding to increase coral resilience in the face of rising ocean temperatures.
