Environmental impacts in the low course of the Pajeú river, in the urban area of Floresta, Pernambuco

Abstract

The colonization and industrialization processes brought the urbanization of Brazilian cities, causing significant environmental and socioeconomic problems. Thus, the municipality of Floresta, which was part of the cattle inland route to the São Francisco River in the colonial period, was occupied by livestock and later grew and specialized in the sectors of agriculture and small industries, which modified the use and land occupation and, consequently, caused environmental impacts. Thus, the present work aims to identify the environmental impacts that occurred in the low course of the Pajeú River, in the urban area of ​​Floresta, analyzing them in a systemic and comparative way the impacts that occurred in the entire hydrographic basin of the Pajeú River and in the light of the laws municipal, state and federal environmental policies, in addition to bringing mitigating measures to these problems encountered. For this, a field visit, bibliographical surveys, construction of a thematic map of the situation of the riparian forest and the interaction network of environmental impacts were carried out. From this, it was found that the study area is quite uncharacterized as to the original situation, as well as in other municipalities in the Pajeú watershed, requiring mitigating actions. Environmental laws exist, however, they lack rigor and compliance with them.
