Resumo
Esta dissertação tem o objetivo de apresentar um estudo sobre as enchentes no interior do estado do Rio Grande do Sul. A cidade de Lajeado foi a escolhida para estabelecer nosso foco de investigação. Embora o tema inundações e enchentes de rios seja recorrente no viver da contemporaneidade, nos mais diversos aspectos, tais como as mudanças climáticas, as alterações da paisagem e da vida humana em lugares de alta vulnerabilidade socioeconômica, ainda se apresenta como um assunto que merece uma abordagem voltada para a história da humanidade e do planeta, entrecruzando as fontes documentais e os aspectos da produção midiática. De todas as formas, as enchentes e inundações sazonais são naturais e os humanos convivem com esses fenômenos desde sua composição como sociedade. Para contribuir com o estudo firmamos como objetivo geral uma análise, a partir da ciência Histórica, de como as enchentes do Rio Taquari interferem nas dimensões sociais e ambientais da comunidade lajeadense. Lajeado é uma cidade do interior do Rio Grande Sul, banhada pelo Rio Taquari e com aproximadamente 80 mil habitantes. Os objetivos específicos consistiram em: (1) Historicizar as enchentes, históricas e recentes, com o auxílio de fotografias e reportagens, respectivamente, dando prioridade para as de maior impacto humano, consideradas desastres ambientais, que atingiram a cidade no recorte temporal estabelecido entre 1970 a 2000; (2) Analisar o processo de urbanização da cidade de Lajeado/RS, buscando relações entre as enchentes e a legislação local; (3) Analisar os episódios das enchentes a partir da imprensa. Para tanto, utilizou-se o método qualitativo. Inicialmente foram aprofundados os conceitos referentes ao tema proposto, buscando construir um marco teórico sólido capaz de sustentar as análises das fontes e fomentar a construção dos resultados. Realizou-se pesquisa documental no arquivo histórico do município de Lajeado/RS, a fim de catalogar as reportagens publicadas pela imprensa local que tenham como assunto “enchentes”. Foram selecionadas 50 reportagens, sendo que 16 delas, as de maior relevância, foram analisadas com maior profundidade; as reportagens foram avaliadas por meio de análise de conteúdo e, ao final, foram analisadas fotos de enchentes históricas do rio Taquari. A partir da análise das reportagens e fotografias, além do aporte teórico, elaborou-se a presente pesquisa a fim de contextualizar e historicizar as enchentes em Lajeado/RS, especialmente as ocorridas entre os anos de 1970 a 2000.
This dissertation aims to present a study on floods in the Rio Grande do Sul (RS) countryside. Lajeado was the city chosen to establish the focus of our investigation. Floods and river floods are a recurring theme in contemporary life and are related to climate change, landscape modifications, and urban life in highly vulnerable socioeconomic areas. Its recurrence makes it a significant subject that deserves an approach concerned with the history of humanity and the planet, which crosses documental sources and media production aspects. In any case, seasonal floods and inundations are natural phenomena, and humans have been dealing with them since the composition of society. Our contribution to the study has as its primary objective to analyze, based on Historical Science, how the floods of the Taquari River interfere with the social and environmental dimensions of lajeadense community. Lajeado is a city in the countryside of Rio Grande do Sul on the bank of the Taquari River and has a population of around 80 thousand inhabitants. Our specific objectives are: (1) to historize the historical and recent floods with photographs and news, respectively. Our priority is the floods with the most significant human impact classified as natural disasters from the 1970s and 2000s. (2) to analyze the urbanization process of Lajeado/RS and the relationship between the floods and the local legislation. (3) to analyze the flood events as reported by the press. To do so, we used a qualitative method. At first, we studied the core concepts of the theme; they were essential to building up the theoretical framework on which the source analysis is supported and promoting the framing of results. Then, documental research on the city archives was made to catalog the news published by the local press with the 'floods' theme. Fifty reports were selected, and sixteen of them, being of more significant relevance, were analyzed in detail. The reports were evaluated by their content, and the photographs of historical floods of the Taquari River were analyzed. This research was developed to contextualize and historicize the floods in Lajeado/RS, especially those between the 1970s and 2000s.
