Forest plays a significant role in the overall balance of carbon in the atmosphere mitigating or exacerbating the effects of global warming. Forest carbon sequestration can potentially reduce the accumulation of greenhouse gases in the atmosphere. The US Environmental Protection Agency reported that land-use-land-change and forest activities resulted in a 13 percent offset of total U.S. CO2 emissions between 1990 and 2003 (EPA 2005). Globally, it has been estimated that about 11% to 39% of all carbon emissions from human origin come from the forest sector (HAO et al. 1990). Regarding global warming, the balance between forest conservation and deforestation can change forest sector activities from a solution to a problem and vice versa.
