Paper Title
The Role of Mangrove Forests as Ecosystem Carbon Stocks in Climate Change Mitigation; Case of Langkawi Geopark, Malaysia and Qeshm Geopark, Iran

Abstract
One possible way of mitigating or at least slowing the amount of human carbon emission is via afforestation or reforestation of land also the carbon stored, sequestered and released from coastal ecosystems including tidal marshes, mangroves and seagrass meadows in order to incorporate carbon from atmospheric CO2 in to biomass. Blue carbon activities refer to sustainable coastal ecosystems management activities which result in avoided emissions from conversion and degradation, conservation, coastal management and restoration of coastal ecosystems (enhancement of carbon stocks through restoration and reforestation). The main objective of this research is to measure the role of mangrove forests as a Blue Carbon sink in Langkawi to ensure that their carbon sequestration and storage functions are maintained and emissions of greenhouse gases are avoided. The results show the critical role of mangrove forests in Langkawi Geopark as a blue carbon sinks. The progressive decrease in TOC content from the surface to the bottom of sediment cores was similar to earlier studies.
