Resumo
This work seeks to understand how demographic dynamics and changes in land use and
land occupation patterns are related to deforestation in the frontier regions of the
Deforestation Arc in the Amazon. Analysis include temporal and spatial scale and have
been conducted both within the general region and at the level of municipalities.
Initially, we used descriptive techniques to characterize the different phases of land use
and land occupation frontier. Then, a more detailed analysis is performed to identify the
variables that are more related to deforestation in the region through regression models.
Among the evaluated variables, the total pasture area is the one that best explains
deforestation. Demographic variables are not good predictors but, together with social
variables, they work well as indicators of the stage of the frontier. This is because
changes in land use patterns have been shown to be more strongly linked to the increase
in deforestation than, indeed, to population mobility.
