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 KAUST-led study analyzed the impact of natural forests on local temperatures across the globe, finding that forests provide the greatest climate benefits when conserved or restored in their native locations. The analysis showed that forests generally have net global cooling effects in areas where dense tree cover would naturally exist. The research highlights that forests buffer against extreme temperatures, providing warming effects in freezing areas and cooling effects in warm regions. Why it matters: The findings emphasize the importance of regional scientific evidence in guiding land-use and restoration decisions, ensuring effective and sustainable nature-based solutions in the face of climate change.
A KAUST-led research team is deploying DNA sequencing technology originally used on the International Space Station to analyze DNA samples in extreme environments along the Saudi Red Sea coast. The portable technology enables on-site extraction, concentration, and sequencing of samples from coral reefs and mangrove forests, minimizing DNA deterioration. Preliminary results indicate a more diverse and complex microbiome than previously found. Why it matters: This application of space-based technology to marine conservation in the Red Sea could provide critical insights into how coral reefs and mangroves adapt to climate change, informing preservation and restoration efforts.
KAUST Assistant Professor Dana Alsulaiman was named a L'Oréal-UNESCO For Women in Science Middle East Regional Young Talent. Alsulaiman was recognized for her work developing biomarker detection technologies for early and accurate disease detection. KAUST Ph.D. student Lila Aldakheel also received an award for her research on microplastics in mangrove forests. Why it matters: The recognition highlights the rising prominence and impact of female scientists at Saudi institutions in addressing key challenges like healthcare and environmental sustainability.
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.
