LIVESTOCK INFLUENCE IN SPACE DISPERSION OF DEFORESTATION IN SILVES MUNICIPALITY IN CENTRAL AMAZON

Abstract

Geotechnology has seen a change in the way research is done in the forest area, its basic use being spread throughout the world, helping and assisting in the face of problems, such as this case or deforestation. The objective of this work is to analyze the influence of livestock on the spatial dispersion of deforestation in the Central Amazon Region, in the municipality of Silves, Amazonas. Using images of Landsat 5 orbital scenes, TM sensor from the year 2014, provided by INPE (National Institute for Space Research), using the supervised image analysis method for characterization of the coverage of only one, using seven repetitions, three in the areas of the hydrographic basins, four repetitions in the area of ​​highways of access to the municipality and six treatments corresponding to the buffers (area of ​​influence) of length (0.5 km to 3.0 km) varying in 0.5 km, being carried out with Pearson correlation, using geographical coordinates of the properties with livestock exploration and the areas with a class of defloration, together with field observations. The result of the supervised analysis of the images evidenced a taxa of 7% with coverage of only deforestation. About 92% of the deforestation is located within 2.0 km around repetitions in the hydrographic basins. Indicating that the areas close to hydrographic basins with livestock-oriented activities should be priority areas for interventions by public authorities to mitigate deforestation in the region.
