Uso de geotecnologias para avaliação da recuperação de áreas degradadas da restinga da praia de Itamambuca, município de Ubatuba-SP

Abstract

Human actions have always been directly related to land use, because since the beginning, obtaining natural resources has been a means of subsistence, whether for agriculture or the need for civil construction or any other economic activity. These actions modified the plant structure and, consequently, the landscapes. The 2012 Brazilian Forest Code aims to minimize environmental impacts and imbalances caused to native forests, through laws that enable the conservation of permanent preservation areas, to ensure that future generations continue to enjoy natural riches. The presente work aims to carry out a temporal analysis of land use and occupation through the use of orbital images from Landsat-7 satellites, for the years 2013 and Landsat-8, for the year 2023. The aim is to generate data that demonstrate the evolution of the landscape in the Itamambuca hydrographic basin, municipality of Ubatuba-SP, with an emphasis on the restinga, to promote the importance of having a properly preserved area and thus being able to positively influence the quality of life in the terrestrial environment. Through information provided by satellite images, it was possible to quantify the variation of the classes determined within the study area, where it was observed that there was a decrease in vegetation and sand, and a significant increase in the areas of buildings. provide support for decision-making regarding the recovery of degraded areas, for the continued preservation of the Itamambuca beach in the municipality of Ubatuba.
