Resumo
The main goal of this study, conducted in an area comprising
221 municipalities, in which 90% of the deforestation in the Legal Amazon
takes place, was to understand the role of the agrarian structure in the conversion
of forest into pasture and agriculture fields. Linear regression results
indicate that 54%–62% of the variation in deforestation occurred between 1997
and 2004, respectively, and are explained as a function of changes in the
amount of appropriated land in 1995. Likewise, up to 80% of the deforestation
can be well explained by the variation in land concentration. In fact, strong
spatial correlations were found between deforestation hotspots and land appropriation
and land concentration. On the other hand, these critical areas have
insufficient governance, particularly at the federal level. As the results of this
study clearly demonstrate, strong governance and institutional integration, with
emphasis on the territorial ordainment, are mandatory in order to reduce the
rapid pace of deforestation in the Brazilian Amazon.
