Dinâmica de ocupação e passivos ambientais nos assentamentos rurais do município de Goiás-GO

Abstract

Studies are controversial about the influence of the implantation of rural settlements in the deforestation process, some point that there is an acceleration of this process, others already show that in these places the dynamics of land use follows a regional trend. In the Cerrado (the Brazilian savannah) this is still a little-known phenomenon. Our objective was to analyze land useand cover in rural settlements and for the municipality of Goiás, where they are located, with a focus on permanent preservation areas (APPs) of water courses. Geoprocessing and satellite image classification techniques were used for four years (1985, 1991, 1995 and 2018), with a time span of 33 years. To check the pattern of land use in areas inside and outside APPs, in rural settlements and in the rest of the municipality, principal component analyzes were used. The results show that the areas with native vegetation reduced by 33% and 34%, for the settlements and the rest of the municipality, respectively. The classes linked to agricultural activities had an increase between the initial and final year of the study. The occupation of the land by agricultural activities, within the areas of permanent preservation, had a greater reduction in the settlements. We conclude that the dynamics of land use and occupation in the settlements and in the rest of the municipality follow a similar trend, it cannot be saidthat the settlements are responsible for a greater deforestation of native areas of the Cerrado.
