Abstract

The aim of this study is to identify the environmental fragilities on the city of Monte Alto-SP and propose a land use zoning for better environmental management in this region. For this, it was used the methodological proposals of Ross (1994), which addresses potential and emerging fragilities, of Ross and Fierz (2017), which updates some concepts and classifications, and of Gouveia and Ross (2019), which conducts a integration of areas subject to flooding with the proposal of environmental fragility. As a result, it was observed that the class with the greatest predominance was the strong, occupying about 92.29% and 73.58% of the total area of potential and emerging fragility, respectively. To validate the accuracy of the methodology, the coefficient of linear determination (R²) between the obtained emergent fragility degrees and the occurrence of erosive processes present in the respective degrees was used. The erosions were made available by the Technological Research Institute – IPT (2012) and some additional ones were registered by the authors from Google Earth. The determined coefficient of linear determination is 0.6359, which means that the method used developed satisfactory results for the studied location. Finally, environmental zoning was proposed based on land use proposals to improve the environmental management and quality in the region, as the research shows a high environmental fragility in the municipality of Monte Alto-SP.
