Análise geoambiental e da paisagem do município de Faina-GO, a partir do ano 2000

Abstract

This research seeks to develop an integrated geoenvironmental analysis of the municipality's landscape of Faina (Goiás - Brazil), from the year 2000, making it possible to understand the changes in landscape caused by human activities. For this, aspects of the environment were raised physical, with soil types and relief, to understand the relationship between land use and vegetation cover with topography. A temporal assessment of the forms of land use was also carried out, with the data available from the year 2000, in which it was found that agriculture is one of the human activities that most cause the deforestation of the Cerrado in the municipality. Thus, the conception and use of the Cerrado in agriculture puts the biodiversity of the biome at risk in municipality, in which the predominant land cover is pastures. These, in the year 2019, were in 55% of the municipality's area, in different types of soils and reliefs, such as Argisols red-yellow dystrophic, Pétric Plinthosols and in Regional Surfaces of Flattening and Relief of Hills and Hills. One of the explanations for the expressive use of pastures may be due to the increase in the number of cattle herds in the municipality which, since the 2000s, it has approximately 68 thousand animals, which demands a strong structure for feeding the herd. With this, it can be inferred that what remains of coverage Cerrado is in areas of low agricultural suitability, where the types of soil and characteristics of Reliefs prevented, in some way, the advancement of planted pastures. It is expected that new policies come so that these areas already open for pasture use are better utilized and so that more can be produced in smaller areas. In this work, we seek then bring a perspective of the changes from a geoenvironmental analysis, integrating aspects of the physical environment, land use and coverage and demographic and economic dynamics.
