- Alternative Abstract
- Global efforts in reducing anthropogenic carbon emissions in the atmosphere, as a measure of curbing climate change and global warming, can be accomplished in two major ways; reducing emissions from burning fossil fuels, and sequestering CO2 released into the atmosphere. The former involves identifying cleaner sources of energy such as renewables, and improving efficiency of energy systems, the latter requires capturing emitted CO2, either by employing direct Carbon Capture and Storage (CCS) systems, where CO2 from power plants are directly captured and geologically stored underground, or through indirect Carbon Capture and Storage by trees and plants. This research focus is on the indirect Carbon Capture and Storage by trees through afforestation, it shares an insight into the benefits of planting trees, which not only remediates the environment, but also could be key in earning foreign income, especially for developing countries. From the research, the sequestration potential of an afforestation project in Ghana (Forest Investment Program), funded by the Strategic Climate Fund (SCF) under provisions in the UNFCCC, was determined. It shows that, a volume of about 101,173.53 Mg C was sequestered for an area of 3,357.90 ha, in the first four (4) years after establishment, equivalent to 371,306.86 Mg CO2, and this accounts for about 1.85% of total CO2 emission in Ghana (20.1 million tonnes by 2018). The carbon credit value of the sequestered carbon is estimated at $1,990,083.34 USD, representing about 91.50% of total revenue ($2,174,920.37 USD) earned through Timber harvesting in the same region in 2018. The research process considered stem growth and biomass accumulation of 200 selected trees, of four species categories, and using allometric equations, determined the rate of stem growth which was then used as the main input data in a carbon simulation model (CO2FIX) to determine in a year-step, the sequestration potential of the various species and total sequestration potential. The implications of this research, considering just a fraction (stem growth) of total potential of trees planted for carbon sequestration, suggest that, with the appropriate policy driven tool and right silvicultural operations, Afforestation for carbon sequestration could yield great benefits in economic gains for developing countries whiles providing the environmental service of carbon sequestration.
