Carbon Sequestration in Mangroves
31 July 2020
Mangrove forests cover large parts of the tropical coasts where they sequester substantial amounts of carbon (Blue carbon). This high net sequestration rate is of special importance for oceanic mangrove systems, as the build-up of peat is essential to avoid inundation due to sea level rise. Mangroves are being exposed to increasing quantities of external nutrients and labile organic compounds from agricultural runoff and wastewater. This research studied how ongoing eutrophication of mangroves could modify the carbon sequestration potential. Results showed the importance of explicitly considering nutrient inputs when estimating current and future rates of carbon sequestration and the potential risk of drowning of peat-based mangrove systems.
