Resumo: The river basins in urban areas have undergone several negative structural interventions, which have generated changes in the hydrological dynamics. Thus, the present study aims to identify the urban evolution between 1976 and 2014 in the João Mendes river basin and to evaluate the most vulnerable areas in the basin in terms of socioeconomic aspects, which require priority actions, either structural and/or nonstructural measures, by the public power. For that, fieldwork was carried out, generation of the classification map of built-up areas and vegetation cover, and socioeconomic analysis based on income ranges in number of minimum wages by census sector (2010 census) and percentage of households with exhaustion by sector census based on the database provided by IBGE (2010). The results showed that there was an increase of approximately 85% of urban occupation (from 14% to 26.64%) in the basin between 1976 and 2014. It is important that the public power intensifies investments in the census tracts that presented the lowest percentages of households with exhaustion ranging from 0 to 25%.

Así el presente estudio objetiva identificar la evolución urbana entre 1976 y 2014 en la cuenca hidrográfica del Río João Mendes y evaluar las áreas más vulnerables en la cuenca en lo que se refiere a aspectos socioeconómicos, las cuales necesitan acciones prioritarias, sea de medidas estructurales y / o no estructurales por el poder público. Para ello se realizaron trabajos de campo, la generación del mapa de clasificación de las áreas edificadas y de la cobertura vegetal y análisis socioeconómico basado en las franjas de ingresos en número de salarios mínimos por sector censal (censo 2010) y en el porcentaje de hogares con agotamiento por sector de acuerdo con la base de datos proporcionada por el IBGE (2010). Los resultados mostraron que hubo un aumento de aproximadamente el 85% de ocupación urbana (del 14% al 26,64%) en la cuenca entre los años 1976 y 2014. Es importante que el poder público intensifique inversiones en los sectores censales que presentaron los menores porcentajes de hogares con agotamiento que oscilan entre el 0 y el 25%.As bacias hidrográficas em áreas urbanas têm sofrido várias intervenções estruturais negativas, o que gera mudanças na dinâmica hidrológica. Assim, o presente estudo objetiva identificar a evolução urbana entre 1976 e 2014 na bacia hidrográfica do Rio João Mendes e avaliar as áreas mais vulneráveis na bacia, no que tange aos aspectos socioeconômicos, as quais necessitam de ações prioritárias, seja de medidas estruturais e/ou não estruturais, pelo poder público. Para tanto foram realizados trabalhos de campo, geração do mapa de classificação das áreas edificadas e da cobertura vegetal e análise socioeconômica baseada nas faixas de rendimentos em número de salários mínimos por setor censitário (censo 2010) e na porcentagem de domicílios com esgotamento por setor censitário com base no banco de dados disponibilizados pelo IBGE (2010). Os resultados demonstram um aumento de aproximadamente 85% de ocupação urbana (de 14% para 26,64 %) na bacia entre os anos de 1976 e 2014. É importante que o poder público intensifique investimentos nos setores censitários que apresentaram as menores porcentagens de domicílios com esgotamento variando entre 0 e 25%.Universidade Estadual de Londrina2020-01-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3635710.5433/2447-1747.2020v29n1p107GEOGRAFIA (Londrina); v. 29 n. 1 (2020); 107 - 1232447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/36357/26739Copyright (c) 2020 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessLeal, Thiago dos SantosLeão, Otávio Miguez da Rocha2022-09-20T15:53:45Zoai:ojs.pkp.sfu.ca:article/36357Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-20T15:53:45Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
