Diagnóstico da Área de Preservação Permanente do Arroio Raiz na área urbana do município de Condor - RS

Abstract

The intense territorial expansion of urban centers is evident and has been causing increasingly serious social and environmental harm, such as the degradation of rivers, either on their banks or even in water quality. As a result, it is common for these to be used as disposal channels for the release of solid waste, where there is a certain lack of basic sanitation infrastructure. Thus, this study aims to map the permanent preservation area and identify the main impacts present in the urban stretch of Arroio Raiz, in Condor - RS. The Arroio Raiz belongs to the Ijuí River Basin, in which the municipality of Condor - RS is part. The mapping was carried out using geoprocessing tools, while the identification of the main anthropic actions was carried out through on-site visits. It was identified that the study area, through urban expansion, does not have the environmental preservation range proposed in the current legislation in some points, in addition, it was verified the presence of solid waste irregularly thrown directly into the river, or on its banks. Based on this, it is concluded that the area has problems related to its preservation, being necessary, where possible, its isolation for natural recovery or even the planting of forest species, aiming at its regeneration. It is also recommended to map the points of release of domestic sewage, and to carry out awareness campaigns for the population, highlighting the importance of the source for society.
