Sugarcane land use and water resources assessment in the expansion area in Brazil

摘要: Abstract Given that sustainability of Brazilian ethanol is intrinsically associated with the effects sugarcane expansion on land use changes, this paper aims to assess using data such as yield, water requirements, and production costs under rainfed irrigated management. The Paranaiba basin was selected a case study because recent large scale sugarcane. Enhanced Vegetation Index (EVI) methodology used identify dynamics during four crop seasons. Crop through footprint methodology, cane were estimated by combining Agroecological Zone Model CanaSoft. Results show most spatially distributed in central area basin, less potential for yield gain irrigation. This region has significant availability issues. A 54% increase (617,000–947,000 ha) identified, mostly from west, lesser extent southeast. Both areas represent improved edaphoclimatic (soil climatic) conditions, hence, higher yields, lower footprint, managements. Furthermore, there are subbasins quantity problems almost none quality or both concerns, which suggests greater possibilities accessing irrigation; however, an environmental cost practice average, 13 m3 Mg−1 (Mega gram, 106 g) blue footprint. In context highly water-intensive crop, soil climatic conditions enhances Brazil.
