Quantifying the Rapid Sugarcane Expansion for Ethanol Production in the Rio Grande basin, Brazil / Kvantifiering av hastig spridning av sockerrörsplantage på grund av etanolproduktion i Rio Grandes avrinningsområde, Brasilien
The search for sustainable sources of energy has found a realistic replacement to fossil fuels in ethanol and methanol. In response to this trend, sugarcane plantations have rapidly increased in Brazil. In this study, this sugarcane expansion was mapped for the River Grande basin in the northern São Paulo, considering the real extension of the plantation area in 1993, 2000, 2007 using Landsat satellite images. Comparisons between these three different land use scenarios showed a significant expansion of sugarcane plantations from 1993 to 2000 and a slight increase from 2000 to 2007.
