Abstract
There is a steady rise in global temperature and it is attributed to increased levels of carbon dioxide (Co2) in the atmosphere by 30% over the past 150 years. Carbon sequestration is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Cashew plantation, due to their long-lasting nature, prove to both remove carbon and improve soil quality as well as sequester carbon and break the cycle of poverty that leads to deforestation trends. To determine the amount of Co2 absorbed by trees, tree diameter is measured with a vernier caliper and the height using a clinometer. The methodology utilizes non-destructive allometric equations to evaluate the biomass of different tree parts, both above and below ground. The summing of the above-ground biomass (AGB) and below-ground biomass (BGB) would yield the total tree biomass (TB). This approach ensures accurate estimations of carbon stocks at the plot level, which would then be extrapolated to the hectare level for a comprehensive analysis. Subsequently, the census-based approach recommended by VERRA Carbon Standards is used to scale biomass estimates. The Shadman et al (2022) methodology is used to obtain the Tree Dry Weight (TDW), Total Carbon (TC) and the weight of carbon dioxide sequestered in the tree (CO2 weight)
