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.
A KAUST-led international team has published research detailing the potential of marine-based solutions to combat climate change. The study assesses the effectiveness of 13 ocean-based measures, including reducing greenhouse gas concentrations and protecting marine ecosystems. The research will inform decision-makers at COP24. Why it matters: Highlighting the potential of ocean-based solutions can broaden the scope of climate action strategies in the region, where coastal environments and marine resources are vital.
KAUST's coastal wetlands contain 90 hectares of protected mangroves that support over 240 bird species and various marine life. These mangroves, predominantly Avicennia marina, sequester CO2 at a rate 30 times higher than other forests, burying it in sediment. This "blue carbon" storage occurs because the lack of oxygen in mangrove soils prevents the degradation of organic matter. Why it matters: This highlights the critical role of Red Sea mangroves in carbon sequestration and biodiversity, emphasizing their importance for regional climate change mitigation.
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.
A KAUST-led team used acoustic technology and net sampling to explore ocean depths in 146 locations worldwide. They found that the biomass of pelagic organisms in the deep sea is much larger than previously thought, especially below productive waters. Deep-sea fauna migrates to shallower areas to feed, transporting carbon to the deep sea. Why it matters: This suggests the ocean's carbon pump is more effective than previously understood, with implications for climate change mitigation strategies.
