Resumo
This work presents and discusses the results about the expansion of the cultivation of
eucalyptus (Eucalyptus spp) in the Cerrado biome, including the analysis of related variables
in this process. The motivation for this research came from the recognition, using data from
the Brazilian Institute of Geography and Statistic, of the expansion of this crop, mainly in the
state of Mato Grosso do Sul, where it was verified in the last three decades changes in the
landscape with the replacement of cattle raising and agriculture. At the same time, there was a
regression in eucalyptus plantations in Bahia’s west. It can be argued that this expansion and
regression of areas are connected to the presence of forest-based industries in the region that
needs this raw material. Therefore, this study sought to identify areas where they are being
held eucalyptus plantations in the Cerrado with 2006 census data. These locations were
chosen based on these information, and the mapping of the highlighted counties according to
the data from the agricultural census. Then it was analyzed the variables physical, political
economical and social policies in the producing regions. Based on these features were pointed
the prone areas for the expansion of eucalyptus plantation in the Cerrado. In general, the
results show that there are a predominance of some characteristics in the choice of areas to be
cultivated, as a predominant deep sandly quartzly soils, relief in the class of 0 º to 8 º of
declivity and proximity to highways and rivers around 5 km and 3 km, respectively. Another
important result of this research, obtained by the intersection of the areas of eucalyptus to the
Cerrado and the map of land use (PROBIO), indicates that the expansion of this crop is
occurring over areas with remnant Cerrado vegetation.
