Resumo
This research has focused on the land use dynamic in the settlement land projects
located in the state of Goiás with the predominance of intensive agriculture (commodities),
family agriculture and extensive livestock. The main objective is to analyze the influence and
the impacts of different agriculture activities developed regionally over the remaining native
vegetation in the Settlement Projects. Our hypothesis is that different forms of occupation and
economic exploitation in the Cerrado have different impacts on the legal reserve vegetation
found in the rural settlements. Thus we attempted to understand the environmental condition
of the rural settlements in its micro region, analyze the evolution of deforestation within the
settlements and their surroundings, trying to understand the relationship of the developed
agricultural activities with the rural settlements patterns. Our methodology adopted the use of
GIS techniques, satellite image classification (Landsat-TM 5 and RapidEye imageries),
besides the use of geo-referenced data and visiting fieldwork at the settlement samples. The
results indicated that, although the rural settlements have a higher rate of deforestation
(between 1990 – 2010 period), the percentage cleared inside them was less than their
surroundings. This result shows that regions with more intensive land use (with agriculture or
pastures) tend to suffer with a higher pressure of the deforestation, both regionally and within
the settlements. Therefore, the settlements tend to follow the regional dynamics of
deforestation or conservation actions of the area where they are installed, bring the same
agricultural activities of their surroundings. We conclude that the settlements from rural
reform agrarian in the Cerrado biome are not isolated lands from the local reality, while their
small farmers settled can not be characterized as the main actors of the land use changes in Goiás state.
