Abstract

Eucalyptus is the most cultivated species in reforestation in Brazil and has been pointed out one of the best options for the production of charcoal, pulp and paper, biomass and energy. This species is highly influenced by the climatic conditions of the growing site. In this context, it is necessary to carry out studies that seek to evaluate climatic risks and potential production in the different regions of Brazil, under current and future conditions. Thus, the objectives of this project are: a) to adapt, calibrate and evaluate different simulation models of eucalyptus growth; B) to simulate eucalyptus growth in different producing regions in Brazil; and c) to evaluate the impact of variability and climate change on eucalyptus productivity. For this, we will use observed data of eucalyptus productivity from different locations and years, in order to calibrate and evaluate the performance of the MZA-FAO, APSIM, 3PG, CenW and FOREST - DNDC models. With the calibrated models, a sensitivity analysis will be done with respect to the variables air temperature, rainfall, solar radiation and CO2 concentration in the atmosphere. Subsequently, historical series of meteorological data (current scenario) from different producing regions of Brazil will be used to evaluate the impact of variability and climate changes on the productivity of this species. In order to evaluate the future scenarios, five General Circulation Climatic Models (HadGEM2-ES, CSIRO-MK3-6-0, GISS-E2-R, MIROC-ESM and CNRM-CM5) and two scenarios of greenhouse gas emissions (RCP4.5 and RCP8.5) will be considered. Based on the results of this study, we intend to propose adaptation actions for eucalyptus cultivation, in order to mitigate possible negative impacts on forest production. (AU)
