Human intervention into the mangrove forest
for cutting trees, honey collection,
et al. ( 2012 ) estimated that 0.15
1.02 billion ton-
nes of carbon dioxide are released annually, and if
the rate of degradation continues, blue carbon
habitat conversion and clearance will release
centuries to millennia of accumulated carbon over
a few decades (Gordon et al. 2011 ). Apart from
human-induced changes in land use pattern, phe-
nomenon like erosion of river and estuarine banks
also dislodge chunk of blue carbon from their
survival ground (Fig. 8.1 )
Hypersaline condition due to reduced fresh-
water supply from upstream region also triggers
the degradation rate of blue carbon reservoir by
drastically reducing the biomass of the man-
groves. We made an extensive survey since 2005
in the central part of Indian Sundarbans and
observed that even after 8 years,
-
shing and
molluscan shell collection (for lime) also poses
threats to blue carbon community, although the
incidences are extremely local in nature. In
Indian Sundarbans region, poor island dwellers
enter into the deep forest after worshipping the
Goddess Bonobibi (Fig. 8.4 ) for collecting
mangrove timber and other forest products. They
have
rm belief that Bonobibi will be their life-
saver even during tiger attack.

been
identi
ed as an important missing piece or gap
zone in International and National Climate
Change mitigation matrix. The United Nations
Framework Convention on Climate Change
(UNFCCC) primarily aims to reduce green house
gases, conservation and enhancement of sinks
and reservoirs of coastal ecosystem. This process
encompasses the route map to integrate land use

bans, trees of the same species exhibited much
more growth with an average DBH value of
