Rios (in)visíveis em Itabaiana : a questão das águas urbanas no ensino das geociências

Abstract

Discussions about water are an increasingly debated topic, especially in relation to environmental problems in urban centers. Disorderly urban expansion without the accompaniment of sustainable planning limits the availability of water resources. Rivers, streams and streams are channeled, suppressed and filled; Urban drainage systems are linked to sanitary sewage, and solid waste management is precarious, as is the issue of sewage treatment. These problems are present in the daily life of Brazilian urban centers. Based on this, it is necessary to develop and produce knowledge about the dynamics of water, and all the surrounding issues, discussion, reflection and problematization are necessary points to offer the population a critical view of the situation and the basis for demanding improvements in relation to issues of the urban fabric. Thus, this work aimed to analyze the problem related to the channeling systems of water bodies in Itabaiana – SE and to promote the understanding of the importance of sustainable urban planning from the application of a didactic sequence in basic education. To this end, based on fieldwork and analysis of the city's urban expansion process, mapping of Itabaiana's main canals and their areas of influence was produced. This allowed for the analysis of the relationship between the municipality's urban expansion and the increased recurrence of flooding phenomena, as well as the identification of potential future scenarios for urban water overflows in other parts of the city. Based on this material, a didactic sequence was planned and implemented in a 1st-year high school class, focusing on the dynamics of urban water in Itabaiana, Sergipe. In this way, in addition to investigating increasingly frequent urban environmental problems in the city center, it was possible to presente the results and reflections on the issue to the school community, using active learning methodologies.
