KAUST community members planted mangrove trees in the university's coastal wetlands as part of the 2022 Winter Enrichment Program (WEP). Mangrove forests are recognized as important carbon sinks, with KAUST hosting a thriving mangrove forest spanning over 110 hectares. The mangrove planting project was initiated to raise awareness of the negative environmental impact associated with travel-related carbon emissions from events like WEP. Why it matters: This initiative highlights the potential of mangrove forests in carbon offsetting and demonstrates KAUST's commitment to environmental sustainability.
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.
A collaborative research team including KAUST scientists has located a major sink for missing ocean plastic in coastal sediments and mangrove forests of the Red Sea and Arabian Gulf. Core samples showed a pattern of plastic sedimentation aligning with the history of global plastic production since the 1950s. Mangroves efficiently lock up microplastics in coastal soil, with plastic burial rates increasing similarly to global production. Why it matters: The findings highlight the critical role of mangroves in trapping plastic pollution and provide evidence that plastic sedimentation marks the start of a new geological epoch, the Anthropocene.
A new study uses the UNet++ deep learning model and Sentinel-2 satellite data to monitor mangrove dynamics in the UAE from 2017 to 2024. The model achieved a mean Intersection over Union (mIoU) of 87.8% on the validation set. Results indicate a significant increase in mangrove area, primarily in Abu Dhabi, contributing to enhanced carbon sequestration across the UAE.
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.
KAUST collaborated with artist Martha Atienza on an exhibition for the Diriyah Contemporary Art Biennale to highlight the role of mangrove ecosystems. Atienza visited KAUST and Thuwal to explore the local fishing culture and gather materials for her installation. KAUST donated 40 mangrove seedlings to support Atienza's installation, which opened on February 19. Why it matters: This partnership demonstrates KAUST's commitment to sustainability and using art to raise awareness about environmental issues in the region.
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.
KAUST's Hydrology, Agriculture and Land Observation Lab (HALO) uses remote sensing tools like drones to map and monitor agricultural sites, including one of the world's largest olive farms in Al Jouf. They also collaborate with the Ministry of Environment, Water and Agriculture of Saudi Arabia and the Center for Desert Agriculture. HALO's mangrove project focuses on carbon sequestration by Avicennia marina mangroves in the Red Sea as part of the KAUST Circular Carbon Initiative. Why it matters: This research contributes to understanding and promoting the conservation of mangrove ecosystems for carbon neutrality in line with Saudi Arabia's sustainability goals.
