Abstract
The primary objective of this study was to estimate the amount of gas not emitted into the air in areas cultivated with sugarcane (Saccharum offcinarum) that were mechanically harvested. Satellite images CBERS-2/CCD, from 08-13-2004, 08-14-2005, 08-15-2006 and 08-16-2007, of northwestern São Paulo State were processed using the Geographic Information System (GIS)-IDRISI 15.0. Areas of interest (the mechanically-harvested sugarcane felds) were identifed and quantifed based on the spectral response of the bands studied. Based on these data, the amount of gas that was not emitted was evaluated, according to the estimate equation proposed by the Intergovernmental Panel on Climate Change (IPCC). The results of 396.65 km² (5.91% for 2004); 447.56 km² (6.67% for 2005); 511.54 km² (7.62% in 2006); and 474.60 km² (7.07% for 2007), calculated from a total area of 6,710.89 km² with sugarcane, showed a signifcant increase of mechanical harvesting in the study area and a reduction of gas emissions of more than 300,000 t yr-1.
