“…We found a two-to fivefold difference in SAR, as well as in OC and TN burial rates in estuaries across a~120 km coastline. The range in SAR of the studied mangroves (2.1-8.8 mm yr −1 ) was within the global average (7.7 mm yr −1 ; Arias-Ortiz et al 2018), with SAR in the Piraquê-Açu mangrove forests and tidal flats (8.8 mm yr −1 and 18.6 mm yr −1 , respectively) being close to the highest global accretion rates (Breithaupt et al 2014;Kusumaningtyas et al 2019;Wang et al 2019). SAR commonly increase from the low (tidal flats) to high-intertidal (mangrove forests) in estuaries globally, although coastal geomorphology and forest structure may change in relation to regional patterns (Alongi et al 2001(Alongi et al , 2005Sanders et al 2010a;MacKenzie et al 2016;Perez et al 2018).…”

The potential of Blue Carbon as an integral part of global climate change adaptation and mitigation strategies requires quantification of drivers and rates of organic carbon (OC) burial and storage. However, there is limited recognition of how land use impacts benthic assemblages, their bioturbation potential, and OC burial in mangrove forests and tidal flats. Here we evaluated the effects of mangrove deforestation on benthic bioturbation potential (BPc), sediment accretion rates (SARs), and OC and total nitrogen (TN) burial in mangrove soils and tidal flat sediments from three estuaries in tropical Brazil. SARs based on 210 Pb dating varied significantly among undisturbed estuaries (2.1-18.6 mm yr −1) and the OC and TN burial rates were respectively 46% and 16% higher than global averages. The cleared mangrove sites had a twofold lower SAR, 40-fold lower OC burial, and over 100-fold lower TN burial when compared to undisturbed forests, revealing the pervasive impacts of land use. Variation in benthic assemblage structure and BPc among sites suggests that the composition and activity of macrofaunal communities may facilitate OC burial in some cases, yet the global extent and significance of bioturbation requires further study. Our work reveals a strong spatial variability in C burial in undisturbed mangrove forests and a decreased capacity of mangroves to accumulate C and sediments due to land use effects.

“…Indonesia sendiri memiliki area hutan mangrove yang luas. Stok karbon global rata-rata yang dimiliki oleh ekosistem mangrove diperkirakan mencapai 956 Mg C ha −1 , yang jauh lebih tinggi daripada hutan hujan tropis, rawa gambut, rawa asin, dan padang lamun [5]. simpanan karbon di hutan mangrove lebih tinggi dibandingkan simpanan karbon pada tipe hutan lainnya, dimana simpanan karbon terbesar terdapat pada sedimen mangrove.…”

Kadar karbondioksida (CO2) di alam semakin bertambah seiring dengan berkembangnya peradaban manusia. Disisi lain, hutan mangrove dapat menyerap dan menyimpan karbon dalam jumlah yang besar dan waktu yang lama, sehingga mampu berperan dalam mitigasi perubahan iklim. Tujuan dari penelitian ini adalah mengetahui kandungan karbon yang ada pada tegakan, sedimen, dan serasah daun mangrove serta tingkat penyerapan CO2. Penelitian ini dilaksanakan pada November 2019 di kawasan ekosistem hutan mangrove Desa Bedono, Sayung, Demak. Metode yang digunakan dalam pengambilan sampel adalah metode purposive sampling di 4 stasiun dengan total titik sampling 12. Analisis karbon menggunakan persamaan allometrik untuk menghitung simpanan karbon pada tegakan, kemudian untuk sedimen dan serasah daun menggunakan metode Loss on Ignition (LOI). Hasil yang diperoleh yaitu ditemukan 2 jenis mangrove pada lokasi penelitian yaitu Avicennia marina, dan Rhizopora mucronata. Nilai kerapatan jenis masing-masing spesies yaitu 4875 indv/ha, dan 200 indv/ha. Persentase penutupan rata-rata sebesar 76,94%. Kandungan karbon yang ada pada tegakan, sedimen, dan serasah daun mangrove masing-masing yaitu mangrove sebesar 190,257 ton karbon/ha, 480,608 ton carbon/ha, dan 0,00165 ton carbon/ha /hari.

“…Possible reasons for the lack of correlation between soil TOC and distance from shoreline could be due to the inhomogeneous underlying basement rocks and sediments, as well as varying soil depths and development stages. Donato et al (2011) in Kusumaningtyas et al (2018) showed that mangrove ecosystems are also one of the richest ecosystems that absorb and store carbon in 65 tropical regions. Mangroves absorb and store large amounts of organic carbon in sediments and biomass of plants, trees and leaves which makes them an important natural 67 carbon sink (Twilley et al, 1992;Bouillon et al, 2008).…”

Mangroves have a major role as carbon absorption and stock. However, this potential cannot be maximized, due to the high level of mangrove damage. The research question is the extent of the ability of mangroves to absorb carbon dioxide (CO2) and store it in the form of biomass. The purpose of this study was to determine the absorption ability and carbon stock of various types of mangove. The research location was chosen in Pejarakan village, Buleleng Regency, Bali Province, Indonesia as a case study. The method used is non-destructive to obtain diameter data at the height of mangrove trees, by collecting garbage and sediment samples manually on the floor of mangrove forests and to motivate the Government and local communities to restore mangrove forests. The results showed that the high density types of Sonneratia alba turned out to have the ability to absorb and store carbon, compared to other mangrove species. The results showed that S. alba is estimated to have the ability to absorb 57.60 tons of CO2 ha-1 which is equivalent to 15.71 tons C ha-1. While the lowest value is the Osbornia octodonta with the lowest density value. S. alba's ability to store carbon is 5.56 tons of CO2 ha-1 or equivalent to 1.52 tons C ha-1. The conclusion is that S. alba has the highest ability to absorb and store carbon.
