Abstract. Dinilhuda A, Akbar AA, Jumiati, Herawati H. 2020. Potential of mangrove ecosystem as carbon storage for global warming mitigation. Biodiversitas 21: 5353-5362. The mangrove ecosystem in Karimunting Bay of West Kalimantan, Indonesia is one of the conservation areas with an area of 138.2 ha. Vegetation making up of that mangrove ecosystem is dominated by Avicennia marina. The existence of mangroves has a role in carbon storage. The ability to store carbon in mangrove forest ecosystems is four times greater than in other tropical forests around the world. Mangrove stems have the greatest ability in storing carbon by up to 55.52%. The research objective was to analyze the potential for carbon storage in the fringe mangrove ecosystem which was dominated by A. marina. This research method is based on a survey of vegetation density in the field. The survey was carried out in Karimunting Bay in three parts of the bay, north, central, and south. Each part of the bay consists of two locations, namely at the front of the breakwater towards the sea and behind the breakwater towards the land. Each location consisted of a plot of 10 x 10 with five replications. The vegetation parameters measured are the types of growth forms, the mangrove ecosystem species, and the diameter and height of the trees, as well as environmental parameters (pH, temperature, and salinity). Destructive method was used on A. marina stems for estimating analysis of mangrove carbon storage in the laboratory. A. marina stem samples were used to test the carbon content with LOI (Lost on Ignition) analysis. Analysis of changes in mangrove area is based on the 2009 and 2019 landscape images. The results show that the mangrove ecosystem of Karimunting Bay has a total density of 177,480 individuals/ha. The amount of carbon storage reached 99,231 mg/ha in 2019 and predictions of total carbon storage over the last 10 years are as much as 13,717,951 tons. Deposits of carbon in fringe mangrove illustrate the carbon dioxide absorption potential of 36,390,608 tons of CO2. The amount of CO2 absorption in fringe mangrove ecosystem type plays a role in reducing greenhouse gas (GHG) emissions with a conditional target according to the Nationally Determined Contribution (NDC) in 2030 of 834 million tons of CO2 to prevent temperature increases.

Similar to standing trees in the forests, wood products play an important role in enhancing the global sequestered carbon pool, by retaining the atmospheric carbon in a sequestered form for the duration of the functional life of the wood products. This study uses a temporal radiative forcing analysis along with the functional half-life of different wood products to evaluate the impacts of wood products on global warming, including carbon storage and life cycle greenhouse gas production/extraction emissions. The methodology is applied to Washington State’s aboveground biomass and timber harvest data, and to the State’s comprehensive wood products mix. A moderate harvest rate simulation within Washington Biomass Calculator is used to estimate state harvest level, and statewide wood products manufacturing data is used for developing wood product mix estimates. Using this method, we estimate that the temporal carbon storage leads to a global warming mitigation benefit equivalent to 4.3 million tCO2eq. Even after factoring in the greenhouse gas emissions associated with the harvest operations and wood products manufacturing processes, within the temporal model, the results show a net beneficial impact of approximately 1.7 million tCO2eq, on an annual basis. It can further be noted that Washington State’s annual biomass growth in its private forests exceeds its annual harvest, by a significant margin. This net yearly accumulation of biomass in the State’s private forests leads to additional global warming mitigation benefits equivalent to 7.4 million tCO2eq. Based on these results, we conclude that Washington’s private forestry industry is a net global warming mitigator for the State, equivalent to 12% of the State’s greenhouse gas emissions in 2015.

Negative Influence

Anthropogenic impacts, such as deforestation, soil erosion, and carbon dioxide emissions, have a negative influence over global warming due to the increase of CO2 levels in the atmosphere. The sustainable forest management is a way to mitigate climate change owing to the carbon storage capacity of forests. This study highlights the priority of forest management according to the integrated assessment of carbon storage under anthropogenic impacts in the administrative units of Ecuador. In the obtained map, the provinces Guayas, Esmeraldas, and Manabí showed the highest values of 25, 22.85 and 19.9, respectively, followed by two Amazon provinces, Morona Santiago and Sucumbíos. Therefore, we concluded that deforestation, soil erosion, and carbon dioxide emissions were more pronounced on the coast mainly due to agriculture and livestock activities and the forests in these provinces must have priority management. This analysis is useful for planning environmental practices in order to increase carbon storage as a strategy of mitigation for global warming.

Global warming is one of the environmental issues related to climate change. Coastal blue carbon ecosystems such as mangrove and seagrass have ability to combat global warming. Mangrove ecosystem has an important ecological function in efforts to mitigate global warming, by carbon storage. This study was done in Lansa Village mangrove forest and focused on mangrove leaf litter. The purpose of this study was to estimate carbon content in mangrove leaf litter. Leaf litter samples were collected by using a 1x1 m2 litter trap, which was made of black nylon with a mesh size of about 0.2 cm, 8 traps were put under mangrove trees canopy, with a height of 1.5 m above sea level or at the highest tide. The samples were taken and observed every 7 days. The samples were analyzed by using Dry-Ash Method. The results showed that the average litter production of gram wet weight (Gbb) and gram dry weight obtained during the study were 122.97 gbb m2/28 days, 4.39 gbb m2/28 days, 47.69 gbk m2/28 days, 1.83 gb m2/day. The average of mangrove leaf litter biomass is 30.12 g m2. The highest amount of carbon storage in mangrove litter was 19.30 gram C. The average value of the percentage of carbon content of all plots was 31.38% per day. Based on these results the estimated amount of carbon removal in mangrove leaves was 2.16 t C ha-1 y-1 or 337.18 t C y-1.and 1,237.45 t CO2 y-1.Ekosistem mangrove memiliki fungsi ekologis yang sangat penting dalam upaya mitigasi pemanasan global, yakni sebagai penyerap dan penyimpan karbon Hutan mangrove juga memiliki peran sebagai penyerap karbon dioksida (CO2) dari udara sehingga sangat berguna untuk mitigasi perubahan iklim. Tujuan dari penelitian ini adalah untung mengestimasi kandungan karbon pada serasah daun mangrove di hutan mangrove Desa Lansa, Kecamatan Wori, Kabupaten Minahasa Utara. penelitian ini dilakukan menggunakan metode litter trap yang berukuran 1x1 m2, yang terbuat dari nylon berwarna hitam dengan ukuran mata jaring (mesh size) sekitar 0,2 cm, sebanyak 8 buah dipasang di bawah kanopi pohon mangrove, dengan ketinggian 1,5 m di atas permukaan air laut atau pada pasang tertinggi untuk menampung jatuhnya serasah dan diamati setiap 7 hari. Hasil penelitian diperoleh rata-rata produksi serasah gram berat basah (Gbb) dan gram berat kering yang didapat selama penelitian, sebesar 122,97 gbb/m2/28hr, 4,39 gbb/m2/hr, 47,69 gbk/m2/28hr, 1,83 gbk/m2/hr. rata-rata biomassa serasah daun mangrove sebesar 41,07. Jumlah simpanan karbon tertinggi pada serasah mangrove sebesar 19,30 gram C.
