Outline
4. Definition
• Blue Carbon includes ocean blue
carbon that represents carbon
stored in open ocean carbon
pools.
• Coastal Blue Carbon – The carbon
stored in tidal wetlands, which
includes tidally influenced forests,
mangroves, tidal marshes and
seagrass meadows, within soil,
living biomass and non living
biomass carbon pools.

24. Sustainable Development Goals
By 2020, sustainably manage and protect marine and coastal ecosystems to avoid
significant adverse impacts, including by strengthening their resilience, and take
action for their restoration in order to achieve healthy and productive oceans
25. Paris Agreement
• NAMA
• NDC (Art.4)
• REDD+ (Art.5)
• Adaptation (Art.7)
• Loss and Damage (Art.8)
• Green Climate Fund (GCF)
28. • Costal Blue Carbon, including
mangroves and segrass meadows
have huge potential for CC A&M
• Promoting ES provided by coastal
BC is timely
• Managing coastal BC including
restoration are biophysically and
socially complex but possible
• Coastal BC is globally recognized and
should be mainstreamed in the
(sub)national agenda
Concluding remarks
We have been working in pan tropical region covering 25 countries with the distribution shown here
Scientific community has recognized the wide range of services that coastal ecosystems can provide
Salt marshes, mangroves, and seagrass meadows are unique ecosystems that support aquatic biodiversity, provide hatching ground and nursery for fish, protect coastal zones from storm surges, wave and tsunami
They are also large storehouse of coastal Blue Carbon
The rates of C burial of these coastal ecosystems is significantly higher than any terrestrial ecosystems
Notably, mangrove is capable of capturing and storing C, as large as five times than lowland tropical forests that are mostly reside in sediments
Intact coastal BC has to be protected for CC mitigation and human well-being.
However, mangroves are among the most threatened and rapidly disappearing natural ecosystem
Deforestation rate of around 13 Mha of mangrove, mainly for aquaculture development is well above 1% per year
GHG emissions due to unsustainable coastal development is up to 1 Billion tons of CO2-eq per annum or 20% of emission from global deforestation
It is resulting a global economic loss of US$ 6-40 B
Mangrove conversions also leave millions of hectares of abandoned and degraded coastal wetlands
On the other hands, mangroves ecosystems enhance coastal resilience from SLR
With high scenario, the SLR by the year 2100 is almost 1 m
Scientists also predict that under high scenario, the interior mangroves will survive until 2070, while the fringe mangroves can only survive until 2055
Mangroves offer strategic measures to cope with SLR, hence adaptation to CC

Most sediment accreted in the mudflat when mangroves are preserved
Past accretion is not observed using 210Pb
Again, mudflat accumulate carbon the most (ca. 7 ton/ha/yr) and fringe accumulate the least due to waves and current
