Abstract:
Biofuels has emerging in Brazil as a viable option for a more sustainable future. Although it is necessary to assess land use, biomass production and water resources use for bioenergy production. The goal of this work was to evaluate the sugarcane productivity (potential and attainable) and the related water use considering potential areas of expansion for sugarcane cultivation within the Center-South region of Brazil. For attainable and potential productivity estimation it was applied the Agroecological Zone Model (AZM) implemented by LNBR team. The study area was the main six producing states of sugarcane in Center-South region. Therefore, productivity and water footprint were estimated throughout the same area. This work will support the assessment of sugarcane performance regarding potential and attainable yield and the related water footprint estimations. Therefore, it will be possible to indicate which are the areas in Brazil where sugarcane cultivation will produce satisfactory amounts of biomass in an efficient way regarding water use. Moreover, by producing more biomass using less water, it will be possible to quantify different requirements of land for different productivity and water scenarios.
