Abstract

Global warming and climate change due to escalating concentrations of carbon dioxide is a major issue of global concern today. Scientists have observed that CO2 concentrations in the atmosphere have been increasing significantly over the past century, compared to the pre-industrial era (280 ppm). The recent average CO2 concentration recorded at Mauna Loa observatory was 418.90 ppm (July 2022). Anthropogenic activities like burning of fossil fuels, land use change and deforestation along with fuel combustion activities, industrial processes and natural gas processing were reported to be the major carbon dioxide emissions sources. The increased atmospheric carbon dioxide levels have led to several adverse consequences and reduction of these carbon dioxide concentrations in the atmosphere can be achieved via carbon sequestration strategies. Among the various physical, chemical and biological carbon sequestration strategies, the biosequestration employing the trees has gained much attention as it offers an ecofriendly approach. Though the significance of forested areas in carbon sequestration has been well studied and documented, few attempts have been made to monitor the potentials of urban forests/ green spaces. In the present study an attempt has been carried out to assess the carbon sequestration potentials of selected trees of Swaraj Round, Thrissur, Kerala. For the present study trees belonging to the outer belt of Swaraj round were identified up to species level along with common name and the carbon sequestration efficiencies were worked out. Upon comparing the carbon assimilation potentialities of trees, the tree species belonging to Fabaceae family members were noted with enhanced carbon sequestration potentials. The present study highlights the significant role of urban green spaces which acts a local carbon sink.
