According to Calzadilla et al. (2013), global agricultural production is expected to decrease by 0.5% in the medium and 2.3% in the long termo Besides that, the distribution of harvested land is expected to change, implying modifications on production and intemational trade patterns (Calzadilla et al., 2013). In Brazil, global climatic changes are supposed to influence agriculture, which is responsible for 22% ofthe Brazilian gross national product (CEPEA, 2013),Adaptation ofproduction systems and mitigation of greenhouse gas emissionsare the main challenges imposed by global climate changes to agriculture.  atropical grasslands  aGLOBAL TEMPERATURE  aMATEMATHICAL1 aPEZZOPANE, J.
