Edaphic Properties

India is voluntarily committed towards reducing carbon emission. Rubber plantation could be an important means for carbon sequestration at state and national level. Tripura holds second position as rubber grower state in India, spreading over 72273 hectare areas. Present study designed to estimate the carbon storage potential, sequestration rate and some selected edaphic properties under four different aged rubber plantations viz. HB05, HB10, HB15 and HB20, following stratified random sampling methodology. Total, 40; 100×10 m transects were laid for estimation of biomass carbon stock and transects were further subdivided in to five equal quadrates 20×10 m sized for sampling soil. The stand structural variables like mean girth size, height, basal area, tree carbon and overall carbon stock significantly varied among the different aged rubber plantations. The periodic annual increment in terms of carbon sequestration was estimated at the rate of 2.97, 3.30, 3.14 and 2.82 (Mg C ha-1 yr-1). The result indicated that total carbon stock in rubber plantation was 202.48 Mg ha-1, out of which tree carbon shared 41.85 and Soil Organic Carbon (SOC) 160.71 Mg ha-1 respectively. SOC did not show any significant variation along the plantation ages. The study suggested that the potentiality of carbon sequestration of rubber plantation in Tripura has immense scope for future carbon credit and incentives.

Assessment And Monitoring

The carbon assessment and monitoring in small scale forests like agroforests are difficult tasks but it creates enormous opportunity as carbon credit. This study aims to assess carbon sequestration potential in agroforestry including soil carbon using google earth imageries. Agroforestry of Ratanpur village in Tanahun district Nepal was selected as the study site. Total agroforests of 19 farmers were selected as the experimental and no agroforests area of 4 farmers were selected as the control site. The high resolution imageries of 2020 and 2015 were acquired from Google earth pro. The digitization was done to classify the image into agriculture, agroforestry, natural trees, settlement areas and others. Total enumeration was done to measure the diameter and height of the plants (tree species) planted in the agro-forest. Moreover, total 69 soil samples were collected from 0-10, 10-20 and 20-30 cm depth. The biomass was calculated using Chave et al. equation while soil carbon was analyzed using Walkley Black method. The biomass was converted into carbon which was used to calculate mean annual carbon increment. The result showed the highest carbon stock was 17.6 kg/ stand of Paulownia tomentosa. Total carbon sequestration potential was 2057.689 kg and its monetary value was US$ 30.863. The mean soil carbon stock of agro-forest was higher 52.92 ton/ha than this of 50.3 ton/ha in agriculture site. The map showed it was 7.63 ha agroforest in map of 2020. The overall accuracy of map of 2015 was 90.91% with Kappa coefficient 0.86 but these values were 80.65% and 0.74 respectively of map of 2020. One-way ANOVA and Post hoc test showed that there was significant difference in species wise carbon stock per stand at 95% confidence level. The research will be useful to understand the carbon stock in agroforestry practices.

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.

The present field experiment entitled ‘Nutrient management and carbon sequestration potential of the rubber-based intercropping system in Western Ghat region of Karnataka’ was conducted at farmers’ field of Harishi village of Soraba taluka of Shivmogga District, Karnataka, India during 2017 to 2019. The experiment was laid out in split-plot design with three replications. Two practices applied on rubber was the application of Farm Yard Manure (FYM) as an organic practice and NPK as inorganic practice and nine treatments consisting of different organic manures biofertilizers and NPK as inorganic fertilizer was applied on Bird’s Eye Chilli (BEC) grown as an intercrop. The results showed that application of NPK on rubber resulted in a maximum mean annual increment in basal diameter (0.56 cm) and crown diameter (0.28 m) in one-year-old rubber and height (0.77 m), basal diameter (0.62 m) crown diameter (0.21 m) in two-year-old rubber. Among nine treatment of BEC, application of NPK resulted in higher growth parameters of rubber at both age levels. Interactions were non-significant on all growth parameters. Age and different manures also influenced the carbon sequestration potential of the system. Hence the application of NPK may be recommended for cultivation of rubber.

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.

This study provides a preliminary assessment of the biophysical potential for carbon sequestration. Quantification of carbon stock and estimation of carbon sequestration potential was carried out in the Kpashimi Forest Reserve, Niger state, Nigeria. Carbon stock was measured in the six vegetation communities existing in the study area. Forty-eight randomly selected 20 x 20 metre quadrats were established wherein data was collected from the main forest carbon pools; including above ground tree, below ground root, undergrowth (shrub grasses), dead wood, litter and soil organic carbon. Biomass of the respective pools was quantified by destructive sampling and use of allometric equations. Thereafter, biomass values were converted to carbon stock equivalent. Four satellite imageries TM, SPOT, ETM+, and NIGERIASAT-1 of 1987, 1994, 2001 and 2007 respectively were used to estimate vegetation cover and carbon stock change over 20 years. The results showed that average carbon stock density (Mg C/ha) of the vegetation communities was in the decreasing order; Riparian forest (123.58 ± 9.1), Savanna woodland (97.71 ± 8.2), Degraded forest (62.92 ± 6.1), Scrubland (36.28 ± 4.1), Grassland (18.22 ± 5.1), and bare surface (9.31 ± 3.1). Deforestation and forest degradation between 1987 and 2007 have resulted in emission of 240.2 Mg (ton) C ha-1 at an annual rate of 12.01 Mg C ha-1. This suggests that the study site has carbon sequestration potential of 240.2 Mg C ha-1 based on its capacity to increase carbon stock through restoration; back to speculated 1987 levels and even higher. Thus, the study recommends the need to analyse carbon offset project feasibility in the study area.

<p>Reducing carbon footprint has increasingly become an important topic regarding the management of industries and universities from different fields. Newcastle University promised to achieve the goal of net-zero carbon dioxide emissions by 2040, and the first process from this ambitious target is to produce a 43% reduction by July 2020, against a 2005/06 baseline. According to the report from Carbon Management Plan 2019 of Newcastle University, there are still 1,720 tons of carbon that should be reduced or offset during this year.</p><p>Two farms were investigated in this project: Nafferton Farm (NF) and Cockle Park Farm (CP) . Soil sampling was conducted within each field at three depth increment (0-30 cm, 30-60 cm and 30-90 cm) separately. Except for soil analysis, this study also chooses some plots in the woodlands around two farms to estimate the carbon storage by various vegetation species, and these two sections will offer comprehensive information about the quality and quantity of carbon in two farms.</p><p>On average, the percentage of total carbon (TC) from all soil profiles was higher under woodland than crop fields in CP. Because the hectare of crop fields is greater than woodland, the sum of total carbon in individual soil layers from the areas is comparatively larger in crop lands, where C stock is 14,122 tons, 6,017 tons, 5,437 tons for the 0-30 cm layers, 30-60 cm layers and 60-90 cm layers, respectively. Meanwhile, the data is 1, 905 tons, 822 tons, and 648 tons for three soil depth layers in the woodland of CP. In Nafferton Farm, the value of TC from the corresponding soil layers is 17,841 tons, 6,844 tons, 6,177 tons separately.</p><p>The results attained so far represent that TC and soil organic carbon (SOC)  in each farm are all statistically significantly different (p< 0.001) with respect to soil depth, but differences were not significant with respect to crop and tree species grown in a single area. Moreover, TC in surface soil of NF is statistically higher (p< 0.01) than that in CP. In Cockle Park Farm, C contents from woodland were considerably higher than those in crop fields (p< 0.001) and the difference of TC and SOC at individual depth layer cannot be ignored. Gross carbon sequestration of plants in woodland is 150.64 tons’ annually, which was calculated by i-Tree Ecosystem Analysis. Simultaneously, the total carbon of trees, including leaf biomass and tree trunks, is in a range of 3,198- 4,096 tons in the woodland of CP. Consequently, the current quality of carbon in topsoil from the whole fields of two farms and the woodland of CP is 35,610 tons which is over four times as high as the estimated carbon emission produced by University in 2019/20 ( 8, 181 tons).</p><p>Overall, it is recommended that the management team of university should attach importance to the operation of two farms. The expectation of mitigating 1,720 ton’s carbon in the short term can be fulfilled if the management department considers converting 58.79 ha crop fields to mixed-species woodland.</p>

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
