Mangrove Avicennia marina in the Red Sea and their role in carbon sequestration and climate change mitigation

Abstract. Mangrove forests, particularly Avicennia marina in the Red Sea, are critical blue carbon ecosystems that play an essential role in global climate change mitigation. This study investigated six mangrove stands in the central Red Sea to examine how nutrient dynamics and physicochemical stressors influence carbon sequestration. Sediment analyses revealed total organic carbon (TOC) values ranging from 1.18% to 4.67%, with δ13C signatures (–29.7‰ to –26.8‰) suggesting both autochthonous and allochthonous carbon inputs. Sites exposed to higher salinity (40.7‰) and temperature (29.3 °C) recorded lower dissolved oxygen (5.2 mg/L) and stronger oxidative stress responses in A. marina leaves, as reflected by elevated catalase, superoxide dismutase, and glutathione-S-transferase activities. Nevertheless, nutrient-enriched sites, such as Rabigh, showed greater biomass and carbon accumulation, demonstrating the resilience of these mangroves under stressful conditions. Conserving and restoring Red Sea mangroves will therefore deliver dual benefits strengthening climate mitigation through CO₂ capture and enhancing ecosystem resilience in arid coastal environments.
