Carbon Sequestration in the Forests of Bangladesh
Abstract Bangladesh has huge degraded forestlands which can be reforested by the CDM projects. To realize the potential of the forestry sector in developing countries for full-scale emission mitigation, understanding carbon sequestration potential of different species in different types of plantations are important. This chapter deals with carbon sequestrating potentials of the A/R activities with the possible incorporation with the CDM in Bangladesh. The chapter finds that generally the forests of Bangladesh can sequester 92 tC ha–1 , on average and 190 tCha–1 in the reforested degraded hill forests in particular. This chapter confirms the potential contribution of the carbon sequestration of the forests of Bangladesh, and positively argues the incorporation of forests with the CDM activities. The A/R CDM policy makers in Bangladesh can get this chapter useful to them.
5.1 Introduction Global climate change is one of the most important issues concerning the international community now-a-days. It concerns the increasing accumulation of GHGs, principally CO2 , in the atmosphere due to industrial emissions and deforestation (Fearnside 2006; Houghton 2005; Nordell 2003). Forest ecosystems are deemed to be an important factor in climate change because they can be both sources and sinks of atmospheric CO2 . They can assimilate CO2 via photosynthesis and store carbon in biomass and in soil (Brown et al. 1996; Graham 2003; IPCC 2000; Lal 2005). Due to the cost-effectiveness in the emission reduction programs having high potential rates of carbon uptake because of the inherent biological growth in the forests and associated environmental and social benefits to the tropical developing countries, increased attention is being focused on tropical forestry to offset carbon emission (IPCC 2000; Moura-Costa 1996; Myers 1996). Tropical forests make up 80% of the total world forests and are recognized as having the greatest long-term potential to sequester atmospheric carbon, via protecting forested lands, slowing deforestation, reforestation, and agroforestry (Brown et al. 1996). Due to deforestation, harvesting, and forest degradation, the world’s forests are estimated to have a net source of 1.8 GtC yr–1 , of which 20% is from tropical deforestation (IPCC 2000).

Carbon Sequestration in the Forests of Bangladesh
et al. (2000) point out that the distribution of both income and GHG emissions is very unbalanced between various world regions. The relative importance of individual gases and sources of emissions differs from region to region. Kram et al. (2000) analyzed that currently developing countries account for about 46% of all emissions, but by 2100 no less they would contribute 67–76% of the global total, while the total income generated in these countries would reach 58–71% from only 16% i
