Abstract

Blue Carbon is a term coined in 2009 to draw attention to the role of vegetated coastal ecosystems (mangrove forests, sea grass meadows and tidal marshes) to mitigate climate change and the need to conserve and restore these valuable ecosystems. Blue Carbon refers to organic carbon that is captured and stored by vegetated coastal ecosystems in sediments and biomass sources. Recent findings have shown that vegetated ecosystems sequester ten times more carbon than tropical forests by area, and thus are extremely valuable for their long-term carbon storage capacity. In this review, the mechanism of carbon storage in coastal ecosystems have been investigated. Blue carbon sources and characterization and, their relationship with climate change as well as possible threats to vegetated coastal ecosystems have also been studied. Finally, in this study the differences between blue carbon and green carbon ecosystems and also the ability of blue carbon to store carbon were investigated.
