KAUST Unveils World’s Largest Coral Restoration Facility on Red Sea Coast to Combat Global Bleaching Crisis

• New facility aims to produce up to 360,000 corals annually and restore 100 hectares of reef by 2030
• KAUST Coral Restoration Initiative targets 2 million coral transplants at Shushah Island

RIYADH — King Abdullah University of Science and Technology (KAUST) has inaugurated a large-scale coral restoration facility on the Red Sea coast, with a goal of producing up to 360,000 corals each year and rehabilitating 100 hectares of reef by 2030.

The launch of what KAUST describes as the world’s largest coral restoration facility was announced during the COP31 climate conference in Antalya, Türkiye, according to a university statement released Wednesday.

The KAUST Coral Restoration Initiative (KCRI) operates a land-based nursery and research campus. It plans to transplant more than 2 million corals across 100 hectares at Shushah Island by 2030 and establish a resilient reef ecosystem by 2040.

The project arrives as coral reefs worldwide face escalating threats from rising ocean temperatures and marine heat waves. The fourth global coral bleaching event, spanning 2023 to 2025, affected more than 84 percent of the world’s reef area, according to the National Oceanic and Atmospheric Administration (NOAA), marking the most severe episode on record. Scientists warn that a strengthening El Niño pattern, projected to intensify through early 2027, could subject vulnerable reefs to renewed heat stress.

KAUST notes that the Red Sea presents unique research opportunities because its corals thrive in some of the planet’s warmest and saltiest waters. This natural resilience may offer insights for protecting reefs elsewhere. The initiative combines the region’s distinctive coral species with KAUST’s marine science expertise to develop scalable cultivation methods and condition corals to withstand warmer waters before outplanting.

The effort also leverages the Coral Research and Development Accelerator Platform (CORDAP), an international initiative advancing scientific and technological solutions for coral conservation.

Research, Artificial Intelligence and Restoration

KCRI integrates four core components: a large-scale land-based coral nursery, sea-based nurseries, more than 50 research programs, and an artificial intelligence-driven monitoring system. Research areas include coral probiotics, heat-resistant coral breeding, robotics, and AI-based modeling.

The initiative employs eCoral, an AI-powered digital twin of the reef system, to identify optimal planting locations and guide ongoing monitoring.

“For the first time, we don’t just have the technology to predict the future of our oceans. We have the power to change it,” said Prof. Carlos Duarte, KAUST distinguished professor and CORDAP executive director. He characterized KCRI as a beacon of hope for the Red Sea and a potential model for global coral restoration.

Building Saudi Scientific Expertise

Saudi scientists, divers, and aquarists are central to the initiative, cultivating specialized skills in coral propagation, marine science, and reef restoration. KAUST frames the project as a long-term investment in the Kingdom’s marine science capabilities, extending beyond immediate environmental objectives.

“When we set out to develop KCRI, the ambition was to tackle a challenge that had never been addressed at this scale,” said Ian Campbell, senior vice president of KAUST’s National Transformation Institute. “Opening the facility is not the finish line. Its success will be measured by results achieved in the Red Sea, the expertise developed in Saudi Arabia, and the contribution our research can make to reef restoration worldwide.”

Amr Atiah, KAUST’s vice president of campus and community and former KCRI director of special projects, emphasized the opportunities the initiative creates for young Saudis. He noted growing interest among youth in marine science careers focused on protecting the Red Sea, and expressed hope that the program would inspire more to enter the field.

Protecting Marine Ecosystems

Coral reefs support roughly a quarter of all marine species, shield coastlines from storms, and sustain the livelihoods of more than 500 million people, according to KAUST. The university said KCRI aims not only to restore the Red Sea’s reef ecosystem but also to develop a framework adoptable by other coral restoration programs globally. KAUST is also collaborating with international partners to safeguard coral diversity for future generations.
