Geoprocessamento aplicado à avaliação de Áreas de Preservação Permanente de nascentes inseridas na área de influência do Complexo Portuário de Suape

Geoprocessing applied to the evaluation of Permanent Preservation Areas of springs located in the area of influence of the Suape Port Complex

Abstract

Springs are water bodies that are essential for the ecological balance of river basins, which are ideal units for use in environmental studies. Therefore, sought to evaluate the springs and their Permanent Preservation Areas, including the microbacteria of Riacho Algodoais, in the area of influence of the Port of Suape, using geotechnologies, such as the Mapbiomas program. The methodology consists of creating thematic maps and collecting quantitative data, analyzing from 2002 to 2022 variations in land use and occupation and contour dynamics that can influence the flow of water in the soil, such as the transport of materials and a possible distribution of contamination in the area. In the selected period, an increase was observed in the Urbanized Area class (+ 77.17%), as well as in Forest Formation (+ 53.51%). However, there was a reduction in the River, Lake and Ocean (-59.55%), which includes the water bodies in the research area. The study showed similarity with related publications, demonstrating that geotechnologies are effective tools for environmental monitoring, with an accurate approach to vegetation cover and contributing to the implementation of appropriate measures. Furthermore, they are essential in preventing and mitigating problems resulting from adverse environmental impacts caused by the interaction between human activities and the environment.
