The Kyoto Protocol provides for the involvement of developing countries in an atmospheric greenhouse gas reduction regime under its Clean Development Mechanism (CDM). Carbon credits are gained from reforestation and afforestation activities in developing countries. Bangladesh, a densely populated tropical country in South Asia, has a huge degraded forestland which can be reforested by CDM projects. To realize the potential of the forestry sector in developing countries for full-scale emission mitigation, the carbon sequestration potential of different species in different types of plantations should be integrated with the carbon trading system under the CDM of the Kyoto Protocol. This paper discusses the prospects and problems of carbon trading in Bangladesh, in relation to the CDM, in the context of global warming and the potential associated consequences. The paper analyzes the effects of reforestation projects on carbon sequestration in Bangladesh, in general, and in the hilly Chittagong region, in particular, and concludes by demonstrating the carbon trading opportunities. Results showed that tree tissue in the forests of Bangladesh stored 92tons of carbon per hectare (tC/ha), on average. The results also revealed a gross stock of 190tC/ha in the plantations of 13 tree species, ranging in age from 6 to 23 years. The paper confirms the huge atmospheric CO(2) offset by the forests if the degraded forestlands are reforested by CDM projects, indicating the potential of Bangladesh to participate in carbon trading for both its economic and environmental benefit. Within the forestry sector itself, some constraints are identified; nevertheless, the results of the study can expedite policy decisions regarding Bangladesh's participation in carbon trading through the CDM.
《京都议定书》规定发展中国家可通过其清洁发展机制参与大气温室气体减排体系。碳信用额来自发展中国家的造林和再造林活动。孟加拉国是南亚一个人口密集的热带国家,有大片退化林地,可通过清洁发展机制项目进行再造林。为了实现发展中国家林业部门全面减排的潜力,应将不同类型人工林中不同树种的碳固存潜力与《京都议定书》清洁发展机制下的碳交易体系相结合。本文在全球变暖及相关潜在后果的背景下,探讨了孟加拉国与清洁发展机制相关的碳交易前景和问题。本文分析了再造林项目对孟加拉国总体及特别是吉大港山区碳固存的影响,并通过展示碳交易机会得出结论。结果表明,孟加拉国森林中的树木组织平均每公顷储存92吨碳(tC/ha)。结果还显示,13个树种、树龄在6至23年的人工林总碳储量为190tC/ha。本文证实,如果通过清洁发展机制项目对退化林地进行再造林,森林将大量抵消大气中的二氧化碳,这表明孟加拉国有潜力参与碳交易以实现经济和环境效益。在林业部门内部,发现了一些制约因素;尽管如此,研究结果可加快孟加拉国通过清洁发展机制参与碳交易的政策决策。
