บทคัดย่อ (EN): Thailand is the world's largest producer of natural rubber. Rubber tree plantation has increased from 1.76 million ha in 1990 to 2.07 million ha in 2007. Rubber tree can be the potential sources of carbon storage, in its biomass of stem, branch, leaf and root. As the economic life of the rubber trees is 25-30 years, about 3-4% of the rubber tree growing area is cut down for replanting annually. This fraction of carbon is used and therefore conserved in the form of furniture or the other rubber wood products approximately 30 years. Moreover, combustion of rubber wood residues for energy is gaining popularity as an industrial substitute for fuel oil. This study aims to evaluate the carbon stock and flow in the rubber tree plantation and utilization in Thailand during 1990-2004. The carbon stocks in living rubber tree (above- and below-ground) were estimated by using allometric equation. GIS spatial analysis technique was applied to quantify soil organic carbon. The carbon emission by rubber tree cultivation and carbon budget in rubber wood products were estimated from survey data and literature review by using IPCC guideline. The annual carbon pool under rubber tree plantation area in Thailand during 1990-2004 was 90.55 million tC. In 2004, the soil organic carbon content in rubber tree plantation at 0-100 cm soil depth was 386.85 million tc. The average accumulations of carbon through furniture products, particle boards, and MDF boards during 1990-2004 were 23.57 tC yr-1. The carbon stocks in the entire rubber wood products in 2004 were estimated to be 50.81 million tC. The annual carbon stock in natural rubber products from rubber tree plantation in Thailand during 1990-2004 was 1.80 million tC yr-1. The annual GHG emissions from burning area for land preparation, fuel use during land preparation, gasoline used in harvested area, diesel used in harvested area, and direct synthetic nitrogen (N) fertilizer application in rubber tree plantation during 1990-2004 were 57,642, 8,116, 70,429, 9,198, and 137,495 tCO2-eq year-1. The annual GHG emissions from transportation of rubber wood between the harvest area and the sawn-wood factory for 1990-2004 periods were 242,353 tCO2 year-1, Emission from electricity used in sawn wood and furniture processing during 1990-2004 was 1,215,761 tCO2-eq yr-1, respectively. The estimating of bioenergy production from waste of rubber wood during 1990-2004 was approximately 142,178 TJ yr-1. During 1990-2004, the potential of residual fuel oil could be substituted by waste of rubber wood approximately 3,575,264,697 liter yr-1 which could be emitting GHG (CO2, CH4 and N2O) about 11,041,910 tCO2-eq yr-1.
