Abstract | The role of C02 sinks has become more broadly known because of its role in the Clean Development Mechanism or Carbon Trading and Kyoto Protocol. The lack of easier, accurate, technically improved and environment friendly approaches for C02 sink quantifications of above ground biomass are leading the slow implementations of the Kyoto Protocol. Many researchers have shown that remote sensing data can be used for approximation ground biomass, seasonal yield and carbon sequestration. Remote sensing technology can be implemented at a regional or global scale to observe vegetation pattern and carbon balance. This research study investigated the use and efficiency of different resolution remote sensing data in the assessment of carbon sequestered by different land covers in Nakhon Nayok province of Thailand. Using allometric equations to calculate C02 sink from aboveground biomass in-situ and accordingly sequestered C02 amount in t/ha, three different resolutions remotely sensed data was used to estimate sequestered C02 amount over the same area. For accounting C02 seqestration this study use the data derived from the Surface Energy Balance Algorithm for Land (SEBAL) and the Carnegie Ames, Stanford Approach (CASA). From the 31 field sample points the sequestered C02 of the study area were compared to the sequestered value derived from the CASA model used on ASTER 15m, LANDSAT 30m and MODIS 250m image. Total 6.12 million ton, 8.33 million ton and 10.39 million ton of sequestered C02 were found for ASTER, LANDSAT and MODIS data respectively. Although the results in this study show a significant relationship between field and model methods, the remote sensing approach shows potential to accurately estimate carbon in fine resolution rather than coarse resolution. For considering the cell number, this model provided different values of sinks for same area, therefore a down scaling initiative was also taken from coarse tomedium and fine resolution for achieving C02 sequestered value of medium and fine resolution image. A scale factor has developed for MODIS 250m resolution image to achieve the result of LANDSAT 30m image. The scale factor for MODIS 250m is 0.801 and for downscaled MODIS 30m is 0.78 to achievthe sink result of LANDSAT 30m which has a significant relationship with real world. Therefore this study gave an insight in the possible application of remote sensing in carbon monitoring and potential of Nakhon Nayok province for CDM projects in Thailand for reducing greenhouse gas emissions to meet their targets when carbon becomes an internationally tradable commodity. |
