Biodiversitas 20: 311-315. Mangrove forest ecosystem has been known for its roles in buffering coastal abrasions and being a reservoir for seafood production. However, very little information is available on its role in sequestering carbon and how its annual growth ability can benefit climate change mitigation. This study aims to determine carbon storage and sequestration by one, three and five-year-old Rhizophora apiculata Blume planted in PT. Ovivipari Bina Semesta (PT. BIOS). This study was conducted for over five months during 2015-2016, in purposively selected mangrove rehabilitation area. It used both harvestings as well as non-harvesting methods for estimation of carbon stock and carbon sequestration. The results show that the mangrove species has a very high ability to sequester carbon per unit area. The amount of carbon stored in plants aged 1 year, 3 years and 5 years were 0.363 tonnes ha-1, 5,591 tonnes ha-1 and 7,240 tons ha-1, respectively. The study also indicated that the carbon stock values obtained by non-harvesting method using allometric equation were higher than the values obtained by harvesting method.

Abstract. Banuwa IS, Afriliyanti R, Utomo M, Yusnaini S, Riniarti M, Sanjaya P, Suroso E, Hidayat W. 2019. Short Communication: Estimation of the above- and below-ground carbon stocks in University of Lampung, Indonesia. Biodiversitas 20: 676-681. University of Lampung in Indonesia has been promoting green campus program since 2004 to meet environmental goals, including specific targets for energy and CO2 reductions. This study was conducted to establish baseline data on the carbon stock and carbon sequestered in the campus of University of Lampung in order to support the program. The above-ground carbon stocks were estimated from tree biomass, understory biomass, and litters, while under-ground carbon stocks were measured by determining the organic carbon in soil. The results showed that the average above-ground carbon stock was 35.65 t.ha-1, consisted of 35.10 t.ha-1, 0.18 t.ha-1, and 0.12 t.ha-1 from trees biomass, understory biomass, and litters, respectively. The average below-ground carbon stock was 317.33 t.ha-1 and the CO2 uptake by plants was 130.74 t.ha-1. The Faculty of Agriculture with the largest area of green open space contributed to the highest carbon stocks and carbon sequestration, while the Faculty of Medicine showed the lowest values. The results could be essential to suggest the climate change mitigation effort, such as the expansion and optimization of green spaces area.

Abstract Background: Ethiopia is endowed with abundant bamboo resources. However, little is known about biomass, carbon sequestration and storage potential of bamboos. Therefore, this study was conducted to estimate the carbon sequestration and storage potential of Oxytenanthera abyssinica forests in Lower Beles River Basin, Northwestern Ethiopia. To this end, A total of 54 circular plots of 100 m2, with plots having a radius of 5.64, were established to conduct the inventory in Assitsa and Eddida bamboo forests, the typical bamboo sites in Lower Beles River Basin. Biomass accumulation of bamboo was estimated using an allometric equation based on diameter at breast height (DBH) and age. Soil samples were taken from two different soil depths (0 – 15 and 15 – 30 cm) to determine soil organic carbon.Results: Results indicate that a total of 1,620 bamboo culms were measured in the bamboo forests. The mean biomass of the bamboo forests in the study area accounted for about 140.11 ± 2.55 Mg ha-1. The mean biomass carbon and soil organic carbon stock of the bamboo forests were 65. 85 ± 1.19 and 69.70 ± 1.83 Mg C ha-1, respectively. Therefore, the mean carbon stock of the O. abyssinica bamboo forests was 135.63 ± 2.33 Mg C ha-1 with 497.8 ± 8.55 CO2 equivalents. Conclusion: Generally, the O. abyssinica bamboo forests of the study area have significant role in climate change mitigation. Therefore, sustainable management of these crucial vegetation resources will enhance their role in carbon sequestration and thereby, climate change mitigation.

Carbon stock is carbon stored both on the ground and land surface as plant biomass, dead plants (necromas), and in soil as soil organic matters. Change in carbon form becomes the basis for calculating emissions, where most of the carbon (C) elements that broken down into the air are usually bound to O2 and become CO2. Deforestation and degradation are the main threats on forest conservation in Indonesia. Deforestation and forest degradation that occur in Indonesia has led to the development of issues as a significant contributor to carbon emissions. The purpose of this study is to estimate carbon stocks in protected area at PT. Muara Sungai Landak Mempawah Regency, West Kalimantan Province. This study used non-destructive sampling. This method, was done by measuring the diameter of the tree and then using an allometric equation that is suitable for estimating biomass. The making of sample plots in this study is stratified on land cover condition and systematic sampling. The results show that carbon stock for the entire area/cover of the protected area of PT. Muara Sungai Landak is 25.970.08 tons. The highest carbon was in old shrubland cover with total of 15.425.15 tons, followed by young thicket 10.356.46 tons C. The smallest stock was in open peat land of 188.46 tons C. The calculation of vegetation in this study show the old shrub cover is 128.8 tons/ha.

ABSTRAKEmisi CO2 yang terakumulasi di atmosfer menyebabkan terjadinya perubahan iklim secara global. Untuk mengurangi dampak perubahan iklim, salah satu upaya yang dapat dilakukan saat ini adalah meningkatkan penyerapan karbon dan/atau menurunkan emisi di atmosfer. Ekosistem mangrove memiliki fungsi ekologis sebagai pereduksi karbon melalui proses sekuestrasi (C-sequestration). Tujuan dari penelitian ini untuk menghitung kerapatan, kandungan karbon dan serapan CO2 serta mengetahui hubungan korelasi kerapatan mangrove dengan kandungan karbon pada tegakan mangrove. Penelitian dilakukan dengan metode non-destructive sampling menggunakan persamaan alometrik. Pendekatan persamaan alometrik yang digunakan yaitu model alometrik biomassa pohon untuk jenis atau tipe ekosistem mangrove yang sudah tersedia atau dikembangkan di lokasi lain. Hasil pengukuran menunjukkan kerapatan tegakan mangrove di area tanam tahun 2004, 2007, dan 2010 adalah 1460 individu/ha, 1868 individu/ha, dan 2128 individu/ha. Biomassa pada area tanam tahun 2004 sebesar 206,77 ton/ha (103,39 ton C/ha, dan menyerap 379,09 ton CO2/ha). Area tanam tahun 2007 memiliki biomassa 293,73 ton/ha (146,86 ton C/ha, dan menyerap 538,50 ton CO2/ha), dan area tanam tahun 2010 memiliki biomassa 260,02 ton/ha (130,01 ton C/ha, dan menyerap 476,67 ton CO2/ha). Berdasarkan hasil penelitian, kerapatan jenis dan umur tegakan mangrove merupakan faktor yang mempengaruhi besarnya biomassa. Hasil uji regresi-korelasi menunjukkan, perubahan kerapatan mangrove akan berpengaruh secara signifikan pada ekosistem mangrove dalam menyimpan karbon dan menyerap CO2 dari atmosfer. Kata Kunci: Mangrove, biomassa, karbon, kerapatan jenis ABSTRACTEmissions of CO2 that accumulated in the atmosphere causes global climate change.  To reduce the impact of climate change, one of the efforts is increased carbon sequestration. The mangrove ecosystem has ecological function as reducing carbon through sequestration process (C-sequestration). Aimed of this research to calculate the density, carbon content and absorption ability CO2 as well as knowing the correlation of mangrove density with carbon sequestration in mangrove. The method used in this research is use non destructive sampling method with allometric equation. The approach allometric equations were used that tree biomass allometric models for the type or types of mangrove ecosystems that are already available or developed in other locations. The measurement results of mangrove density in planting area 2004, 2007 and 2010 were 1,460 individuals/ha, 1868 individuals/ha, and 2128 individuals/ha. Biomass at the planting area in 2004 amounted to 206.77 ton/ha (103.39 ton C/ha, and absorbs 379.09 ton CO2/ha).

The rapid development of infrastructure that occurred in the area of Tanjung Api-api resulted in changes in the function of mangrove land along the coast. Directly, this also impacts on the sustainability of ecological functions of mangroves. This study aims to estimate changes (prior to infrastructure development and current conditions) of aboveground carbon reserves stored in mangrove forests in Tanjung Api-api. This research was conducted in June-August 2016. Carbon stocks in mangrove along Tanjung Api-api were conducted by surveying the mangrove species and density, and then calculating biomass and carbon stock using allometric equation. While changes in carbon stocks are calculated by converting changes in mangrove area before and after infrastructure development to carbon stock value. The change of mangrove area was done by doing image data processing in 2005 and 2016. The results showed that mangrove Tanjung Api-api has 9 species of mangrove with total mangrove aboveground biomass of Tanjung Api-api is 1.1498 Mg.ha-1 and stored carbon of 0.5235 MgC.ha-1 and able to absorb CO2 of 1.1921 MgC.ha-1. The result of satellite image processing shows that there is a reduction of mangrove land of 1056.6 ha during the last 11 years from 9741.15 ha in 2005 (before development) to 8684.55 ha in 2016. Thus, there is a decrease of mangrove biomass by 1214.894 Mg, carbon stock is reduced by 553.090 MgC and CO2 uptake is reduced by 2029.84 MgC. Keywords : aboveground, CO2, mangrove, Tanjung Api-api

Abstract. Some climate scientists are questioning whether the practice of converting of non-forest lands to forest land (afforestation or reforestation) is an effective climate change mitigation option. The discussion focuses particularly on areas where the new forest is primarily coniferous and there is significant amount of snow since the increased climate forcing due to the change in albedo may counteract the decreased climate forcing due to carbon dioxide removal. In this paper, we develop a stand-based model that combines changes in surface albedo, solar radiation, latitude, cloud cover and carbon sequestration. As well, we develop a procedure to convert carbon stock changes to equivalent climatic forcing or climatic forcing to equivalent carbon stock changes. Using the model, we investigate the sensitivity of combined affects of changes in surface albedo and carbon stock changes to model parameters. The model is sensitive to amount of cloud, atmospheric absorption, timing of canopy closure, carbon sequestration rate among other factors. The sensitivity of the model is investigated at one Canadian site, and then the model is tested at numerous sites across Canada. In general, we find that the change in albedo reduces the carbon sequestration benefits by approximately 30% over 100 years, but this is not drastic enough to suggest that one should not use afforestation or reforestation as a climate change mitigation option. This occurs because the forests grow in places where there is significant amount of cloud in winter. As well, variations in sequestration rate seem to be counterbalanced by the amount and timing of canopy closure. We close by speculating that the effects of albedo may also be significant in locations at lower latitudes, where there are less clouds, and where there are extended dry seasons. These conditions make grasses light coloured and when irrigated crops, dark forests or other vegetation such as biofuels replace the grasses, the change in carbon stocks may not compensate for the darkening of the surface.

Alternatives of vegetations to store carbon need to be encouraged considering that forests are threatened by widespread destructions. One such vegetation is grasslands which have the potential for carbon storage and to reduce CO2 concentration in the atmosphere. At present, many enterprises have designed grasslands for many purposes. Grasslands at Cikalong Wetan and Little Farmers, West Bandung Regency were established under different pattern of plantation stands. The purpose of this research was to study the potential of carbon stock in grassland vegetation at these locations. Based on RaCSA method, the tree biomass was determined by nondestructive collection of density and basal area of trees, then calculated by an allometric equation. The ground cover biomass was determined by destructive collection of grass and roots. Total measured biomass was multiplied by 46% to obtain carbon storage. Based on the results, the potential of carbon stock in Little Farmers grassland (159,540 ton ha-1) is higher than in Cikalong Wetan (14,482 ton ha-1). Carbon stored in tree biomass gives the highest contribution to overall carbon stock potential in Little Farmers (94.84%) while carbon stored in below-ground understorey biomass gives the highest contribution in Cikalong Wetan (52.13 %). Different management of grasslands and pattern of plantation stands resulting a different contribution of carbon stock in every carbon pool. In order to maintain the carbon sequestration potentials of these locations, an agroforestry management such as agri-silviculture need to be encouraged. This study gives a comparison of the carbon sequestration potentials between two man-made grassland ecosystems. For many enterprises this study will aid in a management planning of man-made grassland in terms of ecosystem services, that is carbon sequestration.

Alternatives of vegetations to store carbon need to be encouraged considering that forests are threatened by widespread destructions. One such vegetation is grasslands which have the potential for carbon storage and to reduce CO2 concentration in the atmosphere. At present, many enterprises have designed grasslands for animal feed. Grassland at Little Farmers, Cisarua, West Bandung was established for many purposes, i.e. recreation, education, and animal feed. The purpose of this research was to study the potential of carbon stock in grassland vegetation at this location. Based on RaCSA method, the tree biomass was determined by nondestructive collection of density and basal area of trees, then calculated by an allometric equation. The ground cover biomass was determined by destructive collection of grass and roots. Total measured biomass was multiplied by 46% to obtain carbon storage. Based on the results, the potential of carbon stock in Little Farmers grassland is 6,506.23 kg/m2 with the potential for carbon storage below the ground (0.129 kg / m2) was slightly higher than the carbon stored above the ground  (0.101 kg / m2). Carbon stored in ground cover had been proven to be lower than woody plants (6,506 kg / m2). This study has pioneered in finding the carbon stocks potential of a man-made grassland, so it provides basis of an alternative land use that can be encouraged for carbon sequestration. For many enterprises, this study will aid in the conduct and management planning of grasslands with regards to ecosystem services preservation, such as carbon sequestration.

AbstractAside from the greenhouse gas reduction ability of palm oil-based biofuel as alternative to fossil fuels, another essential greenhouse gas mitigation ability of oil palm plantation is in terms of offsetting anthropogenic carbon emissions through carbon sequestration. In this context, this study was done to determine the carbon sequestration potential of oil palm plantations specifically in two areas in Mindanao, Philippines. Allometric equation was used in calculating the biomass of oil palm trunk. Furthermore, destructive methods were used to determine the biomass in other oil palm parts (fronds, leaves, and fruits). Carbon stocks from the other carbon pools in the oil palm plantations were measured which includes understory, litterfall, and soil. Results revealed that the average carbon stock in the oil palm plantations is 40.33 tC/ha. Majority of the carbon stock is found in the oil palm plant (53%), followed by soil (38%), litterfall (6%), and understory, (4%). The average carbon sequestration rate of oil palm plants is estimated to be 4.55 tC/ha/year. It is advised that oil palm expansions should be done on grasslands and barren lands instead of forest lands to avoid incurring “carbon debts”. It is also recommended that oil palms should be mixed with shrub crops species to enhance soil organic carbon as well as increase the aboveground biomass in oil palm plantations.

Mangrove forests in Indonesia play an important role in mitigating climate changes and providing other ecosystem services; however, their extent continues to decline. Information on mangrove community and its carbon stock, especially for Papua, is still limited. This study was conducted to describe vegetation structure and estimate carbon stock in Payumb Coast in Merauke District, Papua. There were three primary mangrove species identified, namely, Avicennia alba, Rhizophora apiculata and Sonneratia alba. Species dominance varied along a gradient of salinity and substrate perpendicular to the shoreline. A. alba is dominant in the closest zone to the shoreline (importance value 205.76%), while R. apiculata is dominant in the farthest zone (importance value 185,35). At the community level, the carbon stock in trees differed significantly between zones (p<0.05), with the highest in the zone dominated by R. apiculata. This study has provided preliminary data on carbon stock estimation at the community level; further studies should be conducted to estimate total carbon stock based on all above- and belowground components. More accurate estimations become important, as it was found that different species could contain significantly different carbon stock; thus producing variation among mangrove communities.
