Resumo: | The growth of urban areas over the past decades has interfered with the dynamics of mangrove ecosystems, hampering the provision of ecosystem services. The aim of the present study was to verify the profile of the distribution of plant species, changes in soil structure and parameters that attest to water quality in periurban mangrove ecosystem by the Itanhaém River, in the municipality of Itanhaém (São Paulo, Brazil). The results obtained in this study, carried out between the years 2017 and 2019, were then confronted with studies conducted between the years 1996 and 1998, reflecting a comparison of almost two decades of increase in urbanization, due to the population increase of 31% between 1997 and 2017. The analysis suggested that there was a change in the composition of plant species in the plots studied, especially in those closer to the Itanhaém River. The results of the sediment analysis showed an increase of organic matter in the soil of the collection stations. The analysis of the water quality in the different collection points showed results in disagreement with the parameters established by the Brazilian Resolutions CONAMA 357/05 and 274/00. From the results obtained, it was possible to verify that the speed with which urban expansion and speculation in coastal cities has been taking place and has led to a degradation of the mangrove ecosystem, emphasizing the importance of monitoring coastal vegetation. |

El objetivo del presente estudio fue verificar el perfil de distribución de especies vegetales, cambios en la estructura del suelo y parámetros que dan fe de la calidad del agua en manglares periurbanos a orillas del río Itanhaém, en el municipio de Itanhaém (São Paulo, Brasil). Los resultados obtenidos en este estudio, realizado entre los años 2017 y 2019, fueron comparados con estudios realizados entre los años 1996 y 1998, reflejando una comparación de casi dos decadas de aumento de la urbanización, debido al aumento poblacional del 31% entre 1997 y 2017. Los análisis sugieren que hubo un cambio en la composición de especies vegetales en las parcelas estudiadas, especialmente en las más cercanas al río Itanhaém. Los resultados del análisis de sedimentos mostraron un aumento de materia orgánica en el suelo de las estaciones de recolección y el análisis de la calidad del agua en los diferentes puntos de recolección arrojó resultados en desacuerdo con los parámetros establecidos por las Resoluciones brasileñas CONAMA 357/05 y 274/00. A partir de los resultados obtenidos, se pudo constatar que la rapidez con la que se viene produciendo la expansión urbana y la especulación en las ciudades costeras ha llevado a una degradación del ecosistema de manglar y se entiende que el monitoreo de la vegetación costera es de suma importancia.O crescimento das zonas urbanas ao longo das últimas décadas vem interferindo na dinâmica dos manguezais, prejudicando a prestação de serviços ecossistêmicos. O objetivo do presente estudo foi verificar o perfil da distribuição das espécies vegetais, alterações na estrutura do solo e nos parâmetros que atestam a qualidade da água em manguezais periurbanos às margens do Rio Itanhaém, no município de Itanhaém (São Paulo, Brasil). Os resultados obtidos neste estudo, realizado entre os anos de 2017 e 2019, foram confrontados com estudos conduzidos entre os anos de 1996 e 1998, refletindo numa comparação de quase duas décadas de incremento na urbanização, em face do aumento populacional de 31% entre 1997 e 2017. As análises sugeriram alteração da composição de espécies vegetais das parcelas estudadas, especialmente naquelas mais próximas ao Rio Itanhaém. Os resultados das análises de sedimento demonstraram incremento de matéria orgânica no solo das estações de coleta e as análises da qualidade das águas nos diferentes pontos de coleta mostraram resultados em desacordo com os parâmetros estabelecidos pelas Resoluções CONAMA 357/05 e 274/00. A partir dos resultados obtidos, foi possível verificar que a velocidade com que vem se processando a expansão e especulação urbana nas cidades litorâneas, tem levado a uma degradação do ecossistema manguezal e entende-se que seja da maior importância haver o monitoramento da vegetação litorânea.Research, Society and Development2021-01-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1065710.33448/rsd-v10i1.10657Research, Society and Development; Vol. 10 No. 1; e23610110657Research, Society and Development; Vol. 10 Núm. 1; e23610110657Research, Society and Development; v. 10 n. 1; e236101106572525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/10657/10451Copyright (c) 2021 Katia Domingues Blotta ; Luciana Lopes Guimarães; Eliane Marta Quinoñes Braz ; Mara Angelina Galvão Magenta; Renan Braga Ribeiro; Fábio Giordano https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBlotta , Katia Domingues Guimarães, Luciana Lopes Braz , Eliane Marta Quinoñes Magenta, Mara Angelina Galvão Ribeiro, Renan Braga Giordano , Fábio2021-02-20T21:19:23Zoai:ojs.pkp.sfu.ca:article/10657Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:40.451011Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
