“…The inclusion of DOM will certainly improve accuracy in emissions and removals reporting, particularly where forest management is applied for wood resource extraction. The highest DOM found in degraded mangrove of 24.34 ± 6.67 Mg ha −1 is comparable with those found in Kenya of 29.92 ± 36.72 Mg ha −1 [ 32 ] .…”

Background Using ‘higher-tier’ emission factors in National Greenhouse Gas Inventories is essential to improve quality and accuracy when reporting carbon emissions and removals. Here we systematically reviewed 736 data across 249 sites (published 2003–2020) to derive emission factors associated with land-use change in Indonesian mangroves blue carbon ecosystems. Results Four management regimes—aquaculture, degraded mangrove, regenerated mangrove and undisturbed mangrove—gave mean total ecosystem carbon stocks of 579, 717, 890, and 1061 Mg C ha−1 respectively. The largest biomass carbon stocks were found in undisturbed mangrove; followed by regenerated mangrove, degraded mangrove, and aquaculture. Top 100-cm soil carbon stocks were similar across regimes, ranging between 216 and 296 Mg C ha−1. Carbon stocks between 0 and 300 cm varied significantly; the highest values were found in undisturbed mangrove (916 Mg C ha−1), followed by regenerated mangrove (803 Mg C ha−1), degraded mangrove 666 Mg C ha−1), and aquaculture (562 Mg C ha−1). Conclusions Using deep layer (e.g., 300 cm) soil carbon stocks would compensate for the underestimation of surface soil carbon removed from areas where aquaculture is widely practised. From a project perspective, deep layer data could secure permanence or buffer potential leakages. From a national GHG accounting perspective, it also provides a safeguard in the MRV system.

“…Globally, mangrove deadwood stock calculated from a review of 76 sites has a mean of 16.9 ± 25.4 and 29.9 ± 36.7 Mg ha −1 or 8.4 ± 12.7 and 15.0 ± 18.4 Mg C ha −1 for standing and downed wood, respectively (Mugi et al, 2022). Deadwood accumulates on the forest floor at rates of 3.2 (1.6-5.7) Mg C ha −1 year −1 , with the lowest contributions in forests where wood is harvested for either fuel or fishing equipment (Mugi et al, 2022).…”

Mangroves are one of the most carbon‐dense forests on the Earth and have been highlighted as key ecosystems for climate change mitigation and adaptation. Hundreds of studies have investigated how mangroves fix, transform, store, and export carbon. Here, we review and synthesize the previously known and emerging carbon pathways in mangroves, including gains (woody biomass accumulation, deadwood accumulation, soil carbon sequestration, root and litterfall production), transformations (food web transfer through herbivory, decomposition), and losses (respiration as CO2 and CH4, litterfall export, particulate and dissolved carbon export). We then review the technologies available to measure carbon fluxes in mangroves, their potential, and their limitations. We also synthesize and compare mangrove net ecosystem productivity (NEP) with terrestrial forests. Finally, we update global estimates of carbon fluxes with the most current values of fluxes and global mangrove area. We found that the contributions of recently investigated fluxes, such as soil respiration as CH4, are minor (<1 Tg C year−1), while the contributions of deadwood accumulation, herbivory, and lateral export are significant (>35 Tg C year−1). Dissolved inorganic carbon exports are an order of magnitude higher than the other processes investigated and were highly variable, highlighting the need for further studies. Gross primary productivity (GPP) and ecosystem respiration (ER) per area of mangroves were within the same order of magnitude as terrestrial forests. However, ER/GPP was lower in mangroves, explaining their higher carbon sequestration. We estimate the global mean mangrove NEP of 109.1 Tg C year−1 (7.4 Mg C ha−1 year−1) or through a budget balance, accounting for lateral losses, a global mean of 66.6 Tg C year−1 (4.5 Mg C ha−1 year−1). Overall, mangroves are highly productive, and despite losses due to respiration and tidal exchange, they are significant carbon sinks.

“…From the search results, 347 pieces of literature will be filtered. In the literature screening, the researcher chooses the title and abstract separately, as Mugi et al (2022) did. The results of the literature screening are only relevant to the management of mangrove ecosystems, and they only look at the last five years, from 2018 to 2022, so that data can be kept up to date.…”

This study examines the past and summarizes the main findings of 35 studies on managing mangrove ecosystems in Indonesia published between 2018 and 2022. The systematic use of the Preferred Items for the Systematic Review and Meta-Analysis (PRISMA) method showed that, in the last five years, mangrove ecosystem management had had a trend that led to the themes of deforestation and natural resource management, as well as to the themes of sustainable development, ecosystems, coastal zones, and forestry, which were the main topics of discussion in 2019. In addition, the words that have become dominant are ecosystem, forestry, and biodiversity. The limitations and gaps identified include aspects of tourist areas, the use of remote sensing, and quantitative and qualitative approaches that can provide knowledge for advancing mangrove ecosystem management studies in the future. Highlights The use of the R method in visualizing some information resulting from the integration of literature on mangrove ecosystem management, which has not been found in Indonesia Identification of research gaps in the form of deficiencies regarding mangrove ecosystem management Several thing that must be carried out in future research regarding mangrove eocosystem management
