Situação ambiental da área de abrangência da nascente do Rio Timbó, João Pessoa-PB

Abstract

The availability of fresh water, especially from the rivers, has been fundamental for the socioeconomic development of cities and municipalities. However, as a result of urban sprawl, cities have generated disorderly patterns of land use and occupation that have led, among other things, to changes in river courses and degradation of river basins. In the municipality of João Pessoa, due to an increasing urban expansion, there was an intense modification in its natural landscape, resulting in the degradation of practically all natural environments. The Timbó river represents one of those environments that has suffered, in a general way, a strong sequence of degradation, a result of the process of the occupation in its surroundings. In view of this reality, we sought to evaluate the environmental situation of this aquatic body, especially in its spring area. For that, analyzes of water quality and environmental impacts were carried out around this region. The data of the environmental impacts showed that the surroundings of this area is impacted in its two margins, especially in the right margin and those of the water analysis showed that, despite this, it presented satisfactory conditions in several occasions, and could even be classified in class 1 based on Resolução CONAMA n° 357/2005. Although the Timbó river has satisfactory water and a relatively expressive vegetation cover, it is necessary to intervene in this area by public institutions so that the impacts that are occurring in this region can be reversed and, thus ensuring the preservation of this ecosystem for the current and future generations.
