The objective of this study was to assess the carbon sequestration potential of cropland amended at different doses of solid household waste compost. Field experiments were conducted during four cropping seasons alternating maize and tomato. Soil samples were collected on experimental plots in 20 cm depth for soil organic carbon content determination using wet oxidation method while bulk density was measured by the core method (volumetric cylinder method) with undisturbed soil samples taken in 0 - 20 cm with steel cylinder of 100 cm3. Carbon sequestration potential varied with carbon content, bulk density and soil depth. The results shown that amount of carbon sequestered under maize cultivation (0.035±0.03 to 0.191±0.03 t C ha-1) was higher than those recorded under tomato growing areas (0.016±0.03 to 0.164±0.02 t C ha-1). Carbon sequestration rates ranged from 0.105±0.01 to 0.573±0.01 t C ha-1 yr-1 under maize cultivation and from 0.048±0.02 to 0.492±0.03 t C ha-1 yr-1 under tomato growing. It is able to conclude that household waste compost application contributes to increase carbon accumulation in soil.

Soil and vegetation were evaluated along IH-35 within Bexar County for carbon content. The objectives of this study were to evaluate the vegetative composition and carbon sequestration potential of vegetation along IH-35. Three 20 m transects were placed at each site and percent vegetative cover was estimated and above ground plant biomass and soil was collected from three 0.25 m2 subplots along each transect. Plant and soil samples were analyzed for carbon content using the loss-on-ignition method. Two non-native grasses, bermudagrass and King Ranch bluestem, were the dominant cover. Bermudagrass was more efficient in absorbing CO2 compared to King Ranch bluestem. The top 10 cm of soil in all samples contained more organic carbon than the lower 10 cm. Collection of field data has been completed and the soil and plant carbon content is being analyzed with the final results presented at the conference.

This study was carried out to analyze the carbon content in different parts of Alnus nepalensis, and to assess the effect of aspect and altitude in the carbon storage in Alnus nepalensis as well as to quantify the total carbon sequestration (stock) in Alnus nepalensis forest in the mid-hills of Kaski District. The inventory for estimating above and below ground biomass of forest was carried out using stratified random sampling technique. The carbon content in different parts of Alnus nepalensis was quantified using combustion method in the laboratory. For determining the soil carbon content, six soil profiles from each aspect were excavated and soil samples were taken from soil profile up to 1 m depth for deep soil and up to bedrock for shallow soils at the interval of 20 cm. Mean carbon content in stem, branches, leaves and bark of Alnus nepalensis were found to be 40.52%, 33%, 9.56% and 16.4%, respectively. Total biomass carbon sequestered in northern aspect was 30.20 t/ha while for southern aspect it was 39.00 t/ha. In both the aspects higher carbon sequestration was observed at an elevation range of 1200-1300m i.e. 34.8 t/ha and 45.6 t/ha in northern and southern aspects, respectively. Soil carbon sequestration in northern and southern aspects was found to be 113.4 t/ha and 169.30 t/ ha, respectively. The total carbon sequestration potential of Alnus nepalensis forest was estimated to be 186.05 t/ha.

Study Sites

Forest soils supporting Sal-Shorea robusta (Roxb. ex Gaertn. f.) plantations in the foot hills of Darjeeling and Kurseong Divisions in West Bengal were studied for their physicochemical characteristics and carbon sequestration potential. Soils are acidic, high in organic carbon and clay content but low in soil reaction (pH) and bulk density (BD). Thick deposit of leaf litter and its decomposition products increase the soil organic carbon (SOC). Significant amount of clay content also increases the moisture content which helps in decomposing the organic matter, reducing the bulk density of soil and reduces erosion. Soil organic matter tends to concentrate with roughly more than half of the soil organic carbon in the upper soil horizons (0-30cm) at all the study sites. Among the study sites, Samardanga block registers lowest SOC while Bamanpukuri block shows highest SOC stock.

Carbon sequestration by trees is one of the most cost-effective and efficient methods to remove carbon dioxide from atmosphere since trees remove and store carbon at higher rates compared to other land covers. Carbon storage by trees typically ranges from 1 to 8 MgC ha-1 yr-1.The carbon is sequestered in different parts of the trees as biomass. The measurements of biomass provide reasonably accurate estimate of the amount of carbon that was removed from lower troposphere over the years. Therefore, the present study investigates and compares the carbon stock of native Azadirachta indica and exotic Conocarpus erectus, which are extensively cultivated in the campus of the University of Karachi, Pakistan. The above-ground and below-ground biomass of 327 trees of A. indica and 253 trees of C. erectus were estimated by using non-destructive method. The average carbon content of A. indica is calculated to be 662.32 + 1144.81 Kg while that of C. erectus is 192.70 + 322.60 Kg. The independent t-test analysis showed significant difference (p < 0.001) between the means of the carbon content of both the species. The carbon contents of two different species were also correlated with bole’s diameter at breast height (DBH) and tree’s height. The analysis demonstrated greater correlation between the carbon content and the DBH of both the species compared to that with their height. The study will help to understand the carbon sequestration potential of two different types of species for planting particularly in urban area of the world.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-5, Issue-2, March-May 2016, Page: 89-97

Regeneration patterns of species population can address climate change by adaptive evolution or by migrating association to survival in their favorable climate and finally decide the particular forest future. This research examined the status of regeneration and carbon sequestration potential in tropical Sal (Shorea robusta) forest of Kanchanpur district, Nepal. For the study, a total of 63 concentric sample plots were investigated by using systematic sampling with 0.5% sampling intensity. Regeneration status of forest was estimated by calculating the density of each species in each developmental phase. The above-ground carbon stock of trees species were estimated using allometric equations. The studied forests had good regeneration status and Shorea robusta was the dominant species in terms of regeneration and carbon stock. Ramnagar community forest had greater number of seedling, sapling and tree than that of the Ganesh community forest. Reverse J-shaped population curves were recorded at both the study sites. This study provided information about the regeneration status, structure, composition and carbon sequestration potential of tree species which is very necessary for conservation and sustainable management of community forests. Studies indicate that community management has increased the carbon stock of forests and also has promoted the productivity of forests by altering the structure and composition of the community forests.

Abstract Background：The fast-growing introduced mangrove Sonneratia apetala is widely used for mangrove afforestation and reforestation in China. Some studies suggested that this exotic species outperforms native species in terms of carbon sequestration potential. This study tested the hypothesis that multi-species mangrove plantations might have higher carbon sequestration potential than S. apetala monocultures.Results: Our field measurements at Hanjiang River Estuary (Guangdong province, China) showed that the carbon stock (46.0±3.0 Mg/ha) in S. apetala plantations where the native Kandelia obovata formed an understory shrub layer was slightly higher than that in S. apetala monocultures (36.6±1.3 Mg/ha). Moreover, the carbon stock in monospecific K. obovata stands (106.6±1.4 Mg/ha ) was much larger than that of S. apetala monocultures.Conclusions: Our results show that K. obovata monocultures may have a higher carbon accumulation rate than S. apetala monocultures. Planting K. obovata seedlings in existing S. apetala plantations may enhance the carbon sink associated with these plantations.

Aim: To estimate the Carbon sequestration potential of trees in Urban green spaces of Pune city. Study Design: The methods suggested by Ravindranath and Ostwald were used for measuring the above and belowground biomass and estimation of carbon pool. Random sampling technique was used to collect soil samples. As the study area were one acre and above, each and every tree was sampled for various parameters. The GPS instrument was used for measuring latitude and longitude of each and every tree. Place and Duration of Study: The gardens developed by Pune Municipal Corporation (total   66 having an area one acre and above) Pune, Three years( from January 2015 to December 2015, January 2016 to December 2016, January 2017 to December 2017) Methodology: The gardens having an area one acre and above were selected for the work. Each and every tree is sampled along with its position on ground by using GPS instrument. Sampling of tree includes measuring Height and Girth at breast height (GBH). Later, the parameters like Volume, Mass, Wood density, Above and Below ground biomass, Total biomass and Total carbon were calculated as per the standard methods given by Ravindranath and Ostwald [1] Soil samples were collected randomly from a depth of 30 cm as it is a zone of highest microbial activity. Walkley‐Black Wet Oxidation method was used to find out soil organic carbon. Results: Total amount of above and belowground carbon sequestered was estimated to be 7,00,507.83 tonnes; litter and deadwood 24,904.05, and soil organic carbon 1879.905; and the sum of all were 7,27,291.785 tonnes. The exotic species sequester 2,69,287.4 tonnes and native sequester 80,966.55 tonnes of carbon. The rates of carbon in active markets are US$ 30 (Thirty dollars) per tonne.  Conclusion: Putting a conservative value of US$ 30 per tonne of CO2 locked in these sampled gardens, this carbon sink of about 7,27,291.785 tonnes of CO2 is worth of US $ 21818753.55 or Indian Rs. 1606733011.422/-It will help in Climate mitigation and reducing the carbon footprints of Pune city.

Mangroves are key ecosystems in strategies addressing the mitigation of climate change through carbon storage in several countries around the world. The main objective of this study is to quantify the carbon storage (above- and below-ground) in the biomass and sediment of mangrove forests (Avicennia marina and Rhizophora mucronata), as well as to estimate the carbon sequestration potential in the Gebel Elba Protected Area along the Egyptian–African Red Sea Coast. The mean recorded soil bulk density in both mangrove species was 1.16 g cm–3, while the recorded mean soil organic carbon (SOC) content was 34.95 g C kg–1. The total mean SOC content was statistically higher in A. marina stands (39.66 g C kg–1) than in R. mucronata stands (33.15 g C kg–1 ). The total mean SOC density for A. marina and R. mucronata amounts to 40.60 kg C m–3. We recorded the carbon sequestration rate of mangrove forests in Egypt as 11.36 g C m–2 year–1 and the total carbon sequestration potential as 5.97 Gg C year–1. The average single tree biomass was notably highly variable between different mangrove species and sites, with a total average tree biomass of 164.8 and 43.7 kg tree–1 for A. marina and R. mucronata, respectively. The results show that the average total tree carbon content is 74.3 and 18.0 kg tree–1 for A. marina and R. mucronata, respectively. While the recorded tree below-ground biomass was 54.1 and 32.6 kg tree–1, and above-ground biomass was 110.7 and 11.1 kg tree–1 for A. marina and R. mucronata, respectively. The recorded average biomass per hectare of mangrove was 74997.1 and 22536.8 kg for A. marina and R. mucronata, respectively. Moreover, the average total tree carbon content per hectare was 33782.3 and 9304.7 kg for A. marina and R. mucronata, respectively. However, for Egypt mangroves (525 ha), the total organic carbon content amounts to 17.73 Gg C for biomass and 5.97 Gg C year–1 for soil, with total of 23.7 Gg C of organic carbon content storage in the mangrove ecosystem in Egypt.

Lateritic soils of West Bengal supporting Sal (Shorea robusta Gaertn. f.) under different management systems viz., by Forest Protection Committee (FPC), Forest Department and without any management were studied to characterize the soils and their carbon sequestration potential. Soils were medium to high in bulk density, low in pH, low to medium in organic carbon, low in clay content and cation exchange capacity. The study reveals that the soils managed FPC contain higher carbon stock in comparison to that of plantation stand (managed by Forest Department) and degraded forest soils (all are in a contiguous area). The FPC management improves the soil health with comparatively high organic matter content which in turn lowers the bulk density, making the soil porous with higher moisture and nutrient holding capacity which ultimately enhances the carbon sequestration of soil. These results will be useful to the planners, forest managers and administrators.
