Avaliação de impactos ambientais em área de preservação permanente urbana, em um trecho do rio Jari, Laranjal do Jari - AP

Abstract

This study addressed the influence of unplanned urbanization and inadequate land use and occupation on the configuration of environmental phenomena, focusing on the negative impacts on urban Permanent Preservation Areas (APP). The general objective of the research was to assess the environmental impacts present in the urban PPA of the Jari River, in the municipality of Laranjal do Jari - AP, identifying their causes and proposing mitigating measures. The methodology employed consisted of bibliographic research and on-site data collection, using a checklist in the study area. Data analysis was performed using an Interaction Matrix, which allowed for the identification, classification, and valuation of the impacts. The results of the on-site assessment revealed the presence of several negative environmental impacts, with emphasis on soil compaction, alteration of water quality due to the disposal of untreated effluents, landscape alteration, and the presence of scattered solid waste. The final valuation of the impacts, carried out by the Interaction Matrix, classified most of the damage as of medium importance, highlighting the severity of the degradation in the PPA. In conclusion, the study provided a detailed environmental diagnosis, confirming that irregular occupation and the lack of adequate sanitary infrastructure are the main vectors of degradation. Mitigating and compensatory environmental measures were proposed. The work aims to contribute to the municipality's environmental management, proposing environmental improvements and assisting in the development of public policies focused on urban sustainability.
