Understanding Blue Carbon and Need of Mangrove Productivity: Reviewing Different Projects along with Assessing their Success Rates and Suggesting Alternatives | Chapter 8 | Surviving Sundarbans: Tragedy and Hope, Edition 1

In this research paper, a detailed explanation of blue carbon and carbon sequestration is undergone. A special emphasis has been laid on Sundarban, as it serves to be the delta, having large mangrove forests. The mechanism of carbon capture of mangroves is explained. Also, a comparison of carbon-capturing capacities of different mangrove species is done. Different factors like salinity, temperature, soil type etc. which cause differences in carbon sequestration capacities of different mangrove species are enlisted. Special adaptations that mangroves require to survive in saline conditions are discussed. Discussions about various techniques for improving mangrove productivity till date are conducted. It is observed that although various scientific approaches and afforestation strategies are suggested by the Government to increase productivity in Sundarban, still results are still not as per expectations. The probable reasons behind such failures are highlighted, among which proper site selection, species variety selections and community participation are considered. Threats which are increasing mangrove mortality rates are emphasized. Lastly, alternative approaches like economic valuation methods and guidelines for the plantation of mangroves as bonsai in households are suggested.

Blue Carbon Dynamics in the Sundarban Biosphere Reserve (SBR): Impacts of Climate and Anthropogenic Factors | Chapter 7 | Surviving Sundarbans: Tragedy and Hope, Edition 1

The Sundarban Biosphere Reserve (SBR) in India, known as the world's largest mangrove forest, is a key player in global carbon cycling and other biogeochemical processes, serving as a significant blue carbon ecosystem. Blue carbon pertains to the carbon captured by marine and coastal ecosystems, especially mangroves, seagrasses, and salt marshes. Although various assessments of carbon stock and flux have been conducted over the past decades, there is still a lack of concrete understanding regarding carbon source and sink patterns, particularly in the biodiversity-rich Sundarbans, which encompasses a 10,000 km² mangrove area. To identify research gaps in mangrove blue carbon in this region, a recent decade-long inventory of carbon stock pools (including aboveground, belowground, and soil) and factors affecting carbon mass balance (such as cyclones, salinity, sea level rise, temperature, precipitation, and water-air CO² flux) was summarized. This review emphasizes carbon sequestration, storage in vegetation and soil, and the influence of anthropogenic and climatic factors. Gaining insight into these dynamics is crucial for developing effective conservation strategies and enhancing the SBR's role in mitigating climate change.
