Degradação ambiental da mata ciliar no trecho urbano do Rio Piancó em Pombal - PB

Abstract

Riparian forest is a natural environment composed of native vegetation and wildlife, being essential for the maintenance and balance of terrestrial and aquatic ecosystems. The environmental degradation of riparian forests is one of the main environmental problems of our time. In this study, aimed to diagnose the environmental degradation of the riparian forest in the urban stretch of the Piancó River in Pombal-PB, Paraíba, Brazil. The methodology was conducted through bibliographic research, field visits, photo documentation, geoprocessing tools and environmental impact assessment. A simplified environmental diagnosis was made in the area of influence. The environmental impacts were identified through the methods: Ad Hoc and Check Lists. Then, the forms and intensities of environmental degradation in the area were determined. Finally, measures to control of the environmental degradation were proposed. According to the results, 10 anthropic activities in the area of influence were identified and mapped. There were 19 negative environmental impacts: 01 "Not Significant", 07 "Significant" and 11 "Very Significant", being the biotic environment the most affected in the area. A total of 18 forms of degradation were verified, in which 50% had "moderate" intensity, 33% had "high" intensity, and 17% had "low" intensity. Among the environmental control measures, the following stand out: Propose environmental education and awareness measures for residents and farmers; Promote the recovery of the environmental quality of the river's waters; Treat sewage released directly into the river; and Promote the effective management of the APP.
