THE IMPORTANCE OF DIAGNOSING URBAN PERMANENT PRESERVATION AREAS FOR WATER RESOURCES MANAGEMENT IN GOIÁS: A CASE STUDY IN ITUMBIARA-GO

Abstract

The study aims to diagnose the Permanent Preservation Areas (APPs) in Itumbiara-GO, evaluating their conservation status and proposing measures for environmental preservation and recovery. The research focuses on the watersheds of the Água Suja, Trindade and Pombas streams, located within the urban perimeter of Itumbiara and belonging to the microbasin of the Meia Ponte River. The PPAs in these areas are inserted in the Cerrado biome, with phytophysiognomies of footpaths and riparian forests. The methodology adopted included the analysis of satellite images from 2023, on-site inspections with a camera and a DJI MAVIC-2 drone equipped with a thermal sensor to identify occupations. The APPs were evaluated according to their state of conservation, classified into five categories: Poor, Regular, Good, Excellent and Excellent. The diagnosis revealed degradation of the areas due to disorderly urbanization and irregular occupations, resulting in pollution, loss of biodiversity and increased flooding. Most APPs are in fair or poor condition, highlighting the lack of effective public policies. The study points to the urgent need for planned interventions to balance environmental preservation and sustainable urban development, suggesting the implementation of management and environmental education strategies to improve quality of life and protect natural resources.
