Abstract


Global warming due to increased concentration of greenhouse gases causing climate changes throughout world. Best option to control greenhouse gases, other than the reducing fossil fuel burning, is to plant maximum trees. Trees consume huge amount of carbon as their body growth. This consumption or trapping of carbon is termed as carbon sequestration. Different tree species have different rate to remove and store carbon dioxide from atmosphere. The carbon sequestration rates also depend over regional climate, management practice, topography and texture of soil as well. Biomass accumulation and carbon sequestration comparative study from two different tree species was conducted at the premises area of Sindh Madressatul Islam University Karachi, Sindh, Pakistan by using non harvest methods. This method provides exact measurement of biomass accumulation and carbon removal by sequestration from tropospheric atmosphere layer.Present study reveals that the results of plant height, tree bole diameter at breast level (DBH), above ground biomass (AGB), below ground biomass (BGB), Biomass and carbon sequestration of plant Azardirachta indica were found higher (890 cm, 26.43cm, 298.35kg, 77.57kg, 375.93kg and 187.96 kg) as compared with the results of Conocarpus erectus (796.5cm, 12.10cm, 279.15 kg, 72.57 kg, 351.73kg and 175.86kg) trees.It is suggested that in order to get more carbon sequestrated through tree plantation, preference should always be given Azardirachta indica as compared Conocarpus erectus. This study helps to understand the potential of carbon sequestration of Conocarpus erectus and Azardirachtaindica while planting in urban areas.
