Carbon Stock Density

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.

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

<p>The global carbon cycle has been significantly modified by increased human demand and consumption of natural resources. Billions of tonnes of carbon moves between the Earth’s natural spheres in any given year, with anthropogenic activities adding approximately 7.1 gigatonnes (Gt) of carbon (C) to this flux. On a global basis, the sum of C in living terrestrial biomass and soils is approximately three times greater than the carbon dioxide (CO2) in the atmosphere; with the current soil organic carbon (OC) pool estimated at about 1500 Gt (Falkowski et al. 2000). With total global emissions of CO2 from soils being acknowledged as one of the largest fluxes in the carbon cycle, ideas and research into mitigating this flux are now being recognised as extremely important in terms of climate change and the reduction of green house gases (GHG) in the future. Additional co-benefits of increasing carbon storage within the soil are improvements in a soil’s structural and hydrological capacity. For example, increasing organic carbon generally increases infiltration and storage capacity of soil, with potential to reduce flooding and erosion. There are several management options that can be applied in order to increase the amount of carbon in the soil. Adjustments to land management techniques (e.g. ploughing) and also changes to cropping and vegetation type can increase organic carbon content within the subsurface (Schlesinger & Andrews, 2000). If we are able to identify specific areas of the landscape that are prone to carbon losses or have potential to be modified to store additional carbon, we can take targeted action to mitigate and apply better management strategies to these areas. This research aims to investigate issues surrounding soil carbon and the more general sustainability issues of the Gisborne/East-Cape region, North Island, New Zealand. Maori-owned land has a large presence in the region. Much of this land is described as being “marginal” in many aspects. The region also has major issues in terms of flooding and erosion. Explored within this research are issues surrounding sustainability, (including flooding, erosion, and Maori land) with particular emphasis on carbon sequestration potential and the multiple co-benefits associated with increasing the amount of carbon in the soil. This research consists of a desktop study and field investigations focusing on differences in soil type and vegetation cover/land use and what effects these differences have on soil OC content within the subsurface. Soil chemical and physical analysis was undertaken with 220 soil samples collected from two case-study properties. Particle size analysis was carried out using a laser particle sizer (LPS) to determine textural characteristics and hydraulic capacity. Soil organic carbon (OC) content was determined following the colorimetric method, wet oxidation (Blakemore et al. 1987), with results identifying large difference in soil OC quantification between sampled sites. National scale data is explored and then compared with the results from this field investigation. The direct and indirect benefits resulting from more carbon being locked up in soil may assist in determining incentives for better land-use and land management practices in the Gisborne/East-Cape region. Potentially leading to benefits for the land-user, the environment and overall general sustainability.</p>

Aim: To study the carbon sequestration process in tea based plantation system and to identify more potential carbon sequestration system amongst the tea based cropping system by studying carbon storage in different components of the plantation system. Methodology: The experiment was carried out in the Experimental Garden for Plantation Crops of Assam Agricultural University, Jorhat, Assam. Treatments were made in an on going, long term shade experiment on mature tea bushes, adapted to three levels of shades viz. tea as monoculture; Tea based cropping system with Areca palm and Tea with Albizzia odoratissima. Results: Among different tea plantations, tea-albizzia recorded superior performance, followed by tea-areca palm plantation in respect to biomass accumulation and carbon sequestration. Similarly, higher carbon stock was found in tea-albizzia plantations along with other physiological and edaphic parameters related to carbon sequestration attributed to an increase in carbon stock. Interpretation: Tea-albizzia plantation system has maximum potential for carbon offsetting from the atmosphere as well as carbon storage both above and below ground in the plantation ecosystem which might be helpful for future carbon management and economy as a whole.
