Coastal ecosystem for carbon storage
A newly-publish paper provides more evidence to mangrove ecosystem function as carbon sink.
This paper pointed out that conversion of the small global extent of mangroves contribute to a large proportion global carbon emission, more than that of tropical rainforest. The paper also estimated the emission of carbon from the conversion of coastal ecosystem. The ecosystem being discussed in this paper includes tidal marsh, mangroves and seagrass.
“These coastal ecosystems are a tiny ribbon of land, only 6 percent of the land area covered by tropical forest, but the emissions from their destruction are nearly one-fifth of those attributed to deforestation worldwide,”
“One hectare, or roughly two acres of coastal marsh, can contain the same amount of carbon as 488 cars produce in a year. Comparatively, destroying a hectare of mangroves could produce as much greenhouse gas emissions as cutting down three to five hectares of tropical forest.”
