KAUST is collaborating with Coastline Company to convert Red Sea seaweed, specifically Sargassum, into valuable commodities. This initiative addresses the environmental hazard of decomposing seaweed blooms and promotes local employment and a circular economy. KAUST is exploring the use of Sargassum to produce fabric raw materials, alginate for food, biostimulants for agriculture, and fucoidans for therapeutic applications, processing it in a biorefinery manner. Why it matters: This project aligns with Saudi Arabia's sustainability priorities and demonstrates the potential of marine biomass in various industries, including fashion through collaboration with the Saudi Fashion Commission and PYRATEX®.
KAUST researchers from the Red Sea Research Center (RSRC) and Computational Bioscience Research Center (CBRC) found macroalgae DNA prevalent in the open ocean, up to 5,000 km from coastal areas. 69% of drifting macroalgae sinks below 1,000 m depth, sequestering carbon in deep ocean waters. The study used metagenomes generated by global ocean expeditions Tara Oceans and Malaspina, analyzed via KAUST's DMAP platform and Shaheen supercomputer. Why it matters: The findings confirm the role of macroalgae in carbon sequestration, highlighting their importance in blue carbon assessments for climate change mitigation and underscoring KAUST's contribution to environmental sustainability research.
KAUST Professor Carlos Duarte gave a TED Talk on seagrass, highlighting their importance as marine ecosystems. His research focuses on Zostera marina, the first marine angiosperm to be fully sequenced. Duarte's team discovered massive clones of Posidonia oceanica in the Spanish Mediterranean, estimated to be 200,000 years old, which play a critical role in carbon sequestration. Why it matters: This research underscores the potential of seagrass in mitigating climate change and protecting coastal regions, emphasizing KAUST's contribution to marine science and environmental sustainability.
KAUST's Professor Carlos Duarte contributed to sequencing the genome of Zostera marina (eelgrass), work published in Nature. The research identifies gene loss and adaptation mechanisms related to the plant's transition from land to marine environments. Eelgrass developed salt resistance, which could inform selective breeding for salt-tolerant food crops. Why it matters: Understanding the eelgrass genome can help in conservation efforts and provide insights into plant adaptation to climate change and marine environments.
KAUST, the National Livestock and Fisheries Development Program (NLFDP), and the National Research and Development Center for Sustainable Agriculture (Estidama) are collaborating to explore algae-based biostimulants for agriculture. These biostimulants, derived from marine algae, enhance plant growth and nutrient uptake without the negative impacts of chemical fertilizers. KAUST already operates a commercial-scale algae manufacturing plant capable of producing tons of algae per month for biostimulant production. Why it matters: This initiative positions Saudi Arabia as a leader in sustainable food technology by leveraging algae biostimulants to improve soil health and reduce dependence on imported raw materials.
KAUST and the Saudi Red Sea Authority (SRSA) have signed a Memorandum of Understanding (MoU) to collaborate on biodiversity sustainability and marine environment protection in the Red Sea. The collaboration will focus on assessing the impact of coastal tourism, exchanging expertise, and aligning strategies for new initiatives. The MoU aims to support Saudi Vision 2030 targets through strengthened local partnerships. Why it matters: This partnership demonstrates KAUST's commitment to environmental sustainability and highlights the growing importance of protecting the Red Sea's unique ecosystem amidst increasing tourism and development.
KAUST held a Research Workshop on Blue Carbon on March 20 and 21. The workshop focused on the role of blue carbon ecosystems, such as mangroves and seagrass meadows, in mitigating climate change. Experts discussed the importance of these ecosystems. Why it matters: This highlights growing research and awareness in Saudi Arabia around leveraging natural resources for climate solutions.
International ocean experts convened at COP25's Oceans Actions Day to discuss ocean and coastal climate actions, emphasizing their role in achieving sustainable development goals. Carlos Duarte, KAUST professor of marine science, highlighted the importance of conserving marine ecosystems like mangroves and seagrasses for carbon sequestration and coastal protection. He also noted Saudi Arabia's interest in promoting ocean and coastal climate actions under its G20 Presidency. Why it matters: The event underscores the crucial role of marine ecosystems in mitigating climate change and achieving global sustainability goals, with KAUST playing a prominent role in research and advocacy.
