Above Ground Carbon Stock Through Palm Tree in the Homegarden of Sylhet City in Bangladesh

Abstract

An explanatory survey was conducted to assess the contribution of palm species in carbon sequestration in the homegarden of the Sylhet Metropolitan City Corporation of Bangladesh. Assessment was done by means of two stage random sampling. A total of 10 housing area were selected randomly for the study and 4 common palm tree species were found abundantly. From the observations abundance of palm trees [Areca catechu (175/housing area), Cocos nucifera (145/housing area), Borassus flabellifer (124/housing area) and Phoenix sylvestris (27/housing area)] were found higher in all homesteads in comparison with other species. Study revealed that total organic carbon (MTOC mt/ha) was highest in Cocos nucifera (12.48 mt/ha), followed by Areca catechu (4.20 mt/ha), Borassus flabellifer (3.02 mt/ha) and Phoenix sylvestris (0.59 mt/ha). Total amount of organic carbon stored by palm trees in homestead areas was found 20.28 metric ton/ hector in the study area. Study revealed that palm trees of homestead forest accumulate a good amount of biomass and is a good sinker of organic carbon from the atmosphere. Proper management of palm trees will help to improve the local, national and international community through carbon sequestration.
