Studying Carbon sequestration in mangroves , Kalpitiya © Kumudini Ekaratne, IUCN, 2012
Disturbed mangrove in Puttalam lagoon has created many problems such as loss of habitat, threatening land use pattern of the lagoon, degradation of biodiversity, etc. expansion of shrimp farm and salt pans has become a major reason for habitat destruction. One hidden objective of mangrove restoration is the carbon sequestration. Therefore this project aims to calculate the potential biomass production and likely amount of carbon that can be sequestrated with mangrove rehabilitation in Puttalam lagoon. This project will also help to fill the research gap in quantifying the benefits of mangrove restoration.
The result from the field evaluation had shown that the highest percentage of carbon was in the stilt roots, while the lowest carbon percentage was in leaves and branches. Among the other findings were as follows:-
Around 60% of the population interviewed agreed that mangroves were important in reducing global climate change.
The tradeoff between research and uprooting of plants for analysis should be considered . Uprooting plants for research itself is a problem in the Puttalam Lagoon. Hence, it has been proposed that future carbon sequestration studies should involve only non-destructive methods.
