Abstract

Agriculture is an economic activity highly depends on the weather and climate conditions, being these factors the main responsible for changes in agricultural yield variation along crop seasons. One way to mitigate possible impacts from climate change may be related to agricultural practices adopted. Thus, the hypothesis of this study is that probably, some agricultural management adopted by the sugarcane industry such as soil tillage and irrigation, may increase the resilience on climate change through substantial change in the soil water holding capacity. The probable change in the soil water holding capacity can contribute to the biomass production in restrictive environments, i.e., in areas where water regime is not favorable for cane development. Thus, through an ensemble approach using soil-plant-atmosphere transfer models, long-term information (100 years) about the frequency distribution of sugarcane yield and water balance components (surplus, water deficit and evapotranspiration) in a sugarcane expansion area in Cerrado environment under some future climate change scenarios will be generated. The water balance information will be used for area classification according to performance indicators (resilience, vulnerability and magnitude), which will relate to the possibility of sustainable use of irrigation.
