Diagnóstico ambiental preliminar para recuperação de área de preservação permanente de reservatório artificial: o caso do ‘açude do governo’ em Crateús-CE.

Abstract

This study aimed to assess the conservation status of the margins of the Açude do Governo, in Crateús-CE, delimit its Permanent Preservation Area (PPA) and propose recovery measures for the most degraded area. Using geoprocessing tools, field analysis and drone imagery, an area of approximately 6 hectares was identified with signs of intense degradation, mainly characterized by the irregular disposal of solid waste. The delimitation of the APP, carried out based on regulatory criteria, revealed that a small portion of the degraded area is located within this protection zone, however, it may impact the overall environmental quality of the reservoir, due to its polluting-degrading potential. The proposed measures include the removal and proper disposal of waste, the implementation of revegetation techniques, and the creation of physical barriers to prevent further anthropogenic activities. The recovery of this area is essential for the protection of the water quality of the reservoir and the maintenance of the ecosystem services, directly benefiting the local community. It is recommended to develop a Degraded Area Recovery Plan (PRAD) for the entire reservoir protection area, with continuous monitoring of the area to assess the effectiveness of the implemented measures and the need for adjustments in the recovery process.
