Findings of this study suggest that “restoring mangroves, which are common in tropical shallow marine settings, will lead to notable local #OceanAlkalinityEnhancement across a wide range of scenarios.”

“The process is seagrass & mangroves influence the organic & inorganic cycling of C in sediment, with strong impacts on diffusive #alkalinity fluxes. In carbonate-rich sediment, seagrass & mangroves foster carbonate dissolution, resulting in increased alkalinity production...

Through higher rates of carbon delivery and organic matter recycling mangroves produce a larger sedimentary #alkalinity pool, emphasizing their potentially important role in alkalinity-based #CarbonCapture.”

Furthermore, “the model analysis suggests that restored #seagrass meadows can drive rates of atmospheric CO2 uptake between 0.1 and 0.9 tCO2 ha−1 per year, depending on the background rate of #NetPrimaryProduction.”

“In systems with high background calcium carbonate concentration, the dissolution of calcium carbonate can considerably increase potential #CO2Removal (up to ∼0.9 tCO2 ha−1 per year).”

“The theoretical restoration potential of #seagrass ecosystems is suggested to be between ~8 and 25 million ha, with the result that the #OceanAlkalinityEnhancement associated with extensive seagrass restoration could potentially #remove between ~0.8 and 23 MtCO2 per year.”

Stochastic analysis of model “yields an estimated #CDR potential of ~1–17 tCO2 ha−1/yr, which when combined with an estimated theoretical mangrove restoration potential of ~9–13 M ha yields an estimated CO2 removal potential from restoration-induced #OAE of ~9–221 MtCO2/yr.”

Moreover, the results also suggest “a relatively minor impact of benthic methane (CH4) flux in #offsetting #CO2Removal. Mechanistically, > organic matter availability and < sediment O2 penetration would be expected to lead to enhanced rates of biological CH4 production.”

Restoration costs of seagrass and mangroves ⬇️
“At a nominal carbon price of 100 USD tCO2−1 #alkalinity-based #CO2Removal alone would #offset costs of up to 200–1,200 USD ha−1 annually for the restoration/maintenance of mangrove ecosystems,” research found.
