Mangroves, tidal marshes, and seagrasses have been recognized as blue carbon coastal ecosystems they accommodate large stocks, enable long-term storage, the capacity to control greenhouse gas emissions possess potential reduce rise in atmospheric CO2 levels. In tropical subtropical intertidal zones, mangroves show significant productivity rapid deposition rates. Mangroves play an important role capturing, transforming, storing atmosphere into sediments for a long time displacing organic from zone offshores ocean. also help preventing storms, hurricanes, erosion, waves. Recently, threatened natural anthropogenic activities such urbanization, pollution, aquaculture tourism. They are expected hamper their essential services, defense, breeding grounds aquatic organisms' seafood supply, etc. Despite importance of mangrove forests sequestration well numerous goods services offer humans, including wood non-wood forest products, food, fisheries, medicines, eco-tourism, recreation. These deteriorating at alarming rates, necessitating immediate intervention. Thus, protection, restoration conservation this ecosystem gaining considerable attention researchers across globe. This paper provides information on different adaptations, mechanisms, roles ecosystem, estimation, influencing factors, threats, strategies invaluable habitat.

Deconstructing the mangrove carbon cycle: Gains, transformation, and losses

Ecosphere, Journal Year: 2024, Volume and Issue: 15(3)

Published: March 1, 2024

Abstract Mangroves are one of the most carbon‐dense forests on Earth and have been highlighted as key ecosystems for climate change mitigation adaptation. Hundreds studies investigated how mangroves fix, transform, store, export carbon. Here, we review synthesize previously known emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood soil sequestration, root litterfall production), transformations (food web transfer through herbivory, decomposition), losses (respiration CO 2 CH 4 , export, particulate dissolved export). We then technologies available to measure fluxes their potential, limitations. also compare mangrove net ecosystem productivity (NEP) with terrestrial forests. Finally, update global estimates current values area. found that contributions recently fluxes, such respiration minor (<1 Tg C year −1 ), while lateral significant (>35 ). Dissolved inorganic exports an order magnitude higher than other processes were highly variable, highlighting need further studies. Gross primary (GPP) (ER) per area within same However, ER/GPP was lower explaining sequestration. estimate mean NEP 109.1 (7.4 Mg ha ) or a budget balance, accounting losses, 66.6 (4.5 Overall, productive, despite due tidal exchange, they sinks.

Blue carbon is attracting substantial interest as a natural climate solution. Focus has been on countries with large blue stocks, though the high densities of ecosystems make them suitable for Small Island States small coastal habitats. hold 1806–2892 Tg carbon, and mangroves alone offset >10% land use emissions 11 States, highlighting their potential contribution to national change mitigation if they are protected restored. However, <10% have incorporated into National Greenhouse Gas Inventories or Forest Reference Emissions Levels, only 23% quantitative measurable targets, 36% no mention at all.

Mapping the Link between Climate Change and Mangrove Forest: A Global Overview of the Literature

Forests, Journal Year: 2023, Volume and Issue: 14(2), P. 421 - 421

Published: Feb. 18, 2023

Mangroves play a crucial role in maintaining the stability of coastal regions, particularly face climate change. To gain insight into associations between change and mangroves, we conducted bibliometric research on global indexed database Web Knowledge, Core Collection. A total 4458 literature were analyzed based information article metadata through scientometric analysis citation as well cluster analysis. Results suggest that countries such USA, Australia, China, India, Brazil are showing recent influential mangrove-related keywords blue carbon stock. Interestingly, “carbon stock”, “Saudi Arabia”, “range expansion” “nature-based flood risk mitigation” is among top networks field mangrove forest. The present expected to attract potential leaders research, government, civil society, business advance progress towards sustainability changing meaningfully.

Restoring blue carbon systems

Cambridge Prisms Coastal Futures, Journal Year: 2024, Volume and Issue: 2

Abstract Mangroves, tidal marshes and seagrasses have experienced extensive historical reduction in extent due to direct indirect effects of anthropogenic land use change. Habitat loss has contributed carbon emissions led foregone opportunities for sequestration, which are disproportionately large high ‘blue carbon’ stocks sequestration rates these coastal ecosystems. As such, there been a rapid increase interest using habitat restoration as climate change mitigation tool. This review shows that efforts able substantially blue stocks, while also having positive impact on various gaseous fluxes. However, increases spatially variable, biophysical factors such geomorphic setting. While potentially hundreds thousands hectares may be biophysically suitable restoration, activities still often conducted at small scales with mixed success. Maximizing potential gains through will require managers planners overcome the myriad socioeconomic governance constraints related tenure, legislation, target setting cost, push projects into locations unsuitable plant colonization.

Mangrove ecology guiding the use of mangroves as nature‐based solutions

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(11), P. 2510 - 2521

Abstract Mangroves are implemented as nature‐based solutions (NbS) for coastal protection, climate change mitigation (carbon sequestration) and other services. They play a core role in providing benefits biodiversity, livelihoods human well‐being. Ecological research has informed the use of mangroves NbS, but failure NbS projects often been due to misconceptions about mangrove ecology limited wide range ecological knowledge available. Enhanced spatial temporal variation processes, differentiation among tree species assemblages (including fauna microbial communities) provision ecosystem functions services, will support successful NbS. Knowledge responses interacting pressures uses zone resilient projects. Synthesis . The success can be improved with increased incorporation plants, animals microbes by sharing co‐producing within societies.
