Abstract: Climate change, driven by emissions of greenhouse gases from anthropogenic activities into the atmosphere, has been postulated to manifest phenomena such as extreme climate events as floods and heat waves and global warming. Studies have suggested increasing carbon sequestration in soils may help to remove carbon in the atmosphere in order to slow down the rate of climate change. Many studies of organic carbon stocks and inventories of forest, grassland and agriculture soils have been carried out, but few studies have examined the organic carbon stocks and inventories of urban soils. This thesis thus quantifies the soil organic carbon (SOC) stocks of urban parks in Singapore, examines the influence of factors such as depth, bulk density, vegetation type and the extent of vegetation coverage, geology and land use/cover histories on urban park SOC storages, and attempts to determine the significance of urban park SOC stocks to the carbon stocks of Singapore. SOC stocks of urban parks in Singapore are estimated to be slightly lower than SOC stocks of the primary forest of Bukit Timah Nature Reserve Singapore. Amongst all the factors of influence on urban park SOC stocks, vegetation type, land use/cover histories, bulk density and park management activities such as grass mowing and removal of leaf litter are suggested to have the considerable impact on urban park SOC stocks. Overall, urban park SOC stocks of Singapore are significant contributors to the carbon stocks of Singapore, and may be maximized by improving the considerable factors of influence which are suggested in this study.
