Teerawong LAOSUWAN and Yannawut UTTARUK
The purpose of this study was to estimate the above ground carbon capture in small scale agroforestry areas of Inpang Community Forest Network, Sakon Nakhon Province, Thailand using remote sensing technology. This procedure was conducted from the satellite imagery Landsat 7 ETM+ information, which would be modified by atmospheric correction to verify it and generate Modified Soil Adjusted Vegetation Index 2 (MSAVI-2) along with model of determining Fractional Cover (FC) in order to determine the energy reflectance of vegetation index and fractional cover. The data obtained from the satellite through the above process were brought to determine the correlation with data from field surveys with statistical methods. The resultant equation was the Y = 0.0259e0.067X. Such equation could be used to calculate the above ground carbon capture in the areas of interest. The results of estimating carbon content and carbon equivalent of small scale agroforestry areas with total space of 749.71 rai represented above ground carbon capture volume of 6,171.99 tons per rai or 22,630.63 tons of carbon dioxide equivalents (Ton CO2 Equivalent).
