Description Stock assessment of the blue carbon pool of selected patches of
mangrove sediment in the Vembanad Lake was done using the
standard protocols on a per ha basis and multiplied with the
estimated area to derive the blue carbon stock of the particular
fragmented mangrove stands of the species Avicennia officinalis
(Indian Mangrove), twice (in the post and pre-monsoon) during
October 2017-March 2018. The treatments included ‘aged’,
‘recent’, ‘healthy’ and ‘degraded’ mangroves of the selected
species and ‘control’ without mangroves. The overall mean
carbon stock in the A. officinalis sediments in selected locations
of the Vembanad Lake area was 136.09 Mg C/ha (Mg=mega
gram=1 tonne). This value is far low compared to the mean
global soil organic carbon stock in the mangrove ecosystem
(386 Mg C/ha). This finding suggests ample opportunity for
more carbon sequestration in the selected mangrove ecosystems
in Vembanad Lake, toward climate change mitigation measures.
The treatments differed significantly in the cumulative stock of
blue carbon and layer-wise blue carbon density in sediment
