Carbon Sequestration in the Plantations of Chittagong Hilly Areas of Bangladesh

摘要

The study was conducted in the plantations of 13 tree species of Chittagong hilly areas, Bangladesh, with the objective of quantifying carbon sequestration. It was revealed that there was a gross 191 ton/ha catbon stock in the studied plantations. Thehighest soil(including humus) carbon content(113 ton/ha) was found in the Jarul(Lagerstroemia speciosa) plantation and the lowest(83 ton/ha) was found in the Pine(Pinus caribaea) plantation. Most of the plantations were found to possess the litter carbon contents as 3 ton/ha except Mehegoni(Swietenia mahagoni), Pine(Pinus caribaea) and Dhakijam(Syzygium grande) plantation, which possessed only 2 ton/ha catbon. The results represented that 3 13 ton/ha/year for fuelwood collection and 1.24 ton/ha/year for litter collection by the surrounding people, carbon were lost from the plantations. The net increment of carbon in the plantations was 3 86 ton/ha/year. The study revealed a promising result of carbon sequestration by the plantation species in the Chittagong hilly areas, which shows a potential of plantation species to participate in the international carbon trading.
