SUMMARY:

The Brazilian coastal zone stretches approximately 10,800 km, with extremely complex environmental systems, such as dunes, sandbanks, beaches, reefs, mangroves, lagoons, estuaries, and rocky shores, home to diverse species of flora and fauna. Socioeconomic pressures on coastal areas have resulted in rapid, unplanned urbanization and the degradation of natural resources. On the other hand, the advance of the sea has destroyed and caused irreparable socio-environmental damage to beaches worldwide. However, this supposedly did not occur in the municipality of Nísia Floresta, as the city is far from the sea and its beaches are largely protected by sandstone ridges, despite urban density in these areas. The hypothesis of this study is that, due to the protection of municipal beaches by reefs, there have been no impacts, degradation, or destruction in the coastal zone due to human occupation. Using geotechnology, satellite imagery, and geographic information systems, it was possible to process and analyze the transformation of land use and occupation in the municipality of Nísia Floresta. The results point to disorderly human occupation and significant negative environmental impacts throughout the municipal territory. During the analyzed time period, the urbanized area grew significantly, from 42.56 hectares in 1985 to 1,081.78 hectares in 2022, resulting in the reduction of natural areas, loss of biodiversity, increased soil impermeability, and a greater risk of flooding and heat islands in cities. Furthermore, savanna formation decreased from 2,788.38 hectares to 971.14 hectares, resulting in biodiversity loss and altered ecological balance. The beach area has also suffered negative environmental impacts, such as property destruction, erosion, and the transport and deposition of sediments on beaches. Reefs, which could theoretically minimize the energy of waves that hit them, do not appear to be sufficient to prevent the degradation of the physical environment in many places where human presence is significant.
