Resumo: | The relevance of studies aimed at the understanding of socio-spatial vulnerability is emphasized, with the basin as a spatial cut-off, to support the prognosis and planning for droughts and floods. Thus, the objective of the research was to analyze the socio-spatial vulnerability of the Sub-basin of the Piracuruca River to the occurrence of droughts and floods. The sub-basin is located between the states of Ceará and Piauí, drains an area of 7,704 km2 and is very heterogeneous, both from a biophysical and socioeconomic point of view. The study was applied multivariate statistical model (FA) and method of estimation Principal Components Analysis (PCA), using variables - demographic, infrastructure, basic sanitation, natural, economic and social population - considering the 296 (two hundred and ninety-six) setore census, from the 2010 census. It is noteworthy that from this method / model and integration of the elements Criticity (characteristics and behavior of the population) and Support Capacity (infrastructure), it was possible to construct the Socio-Spatial Vulnerability Index Sub-basin of the Piracuruca river. Thus, the variables used to know the Criticity indicated that in 87 (29.4%) sectors of the Sub-basin predominate the upper class. In turn, it was inferred through the Capacity of Support that 137 (46.3%) sectors of the Sub-basin are in the very high class. However, the socio-spatial vulnerability index indicated the predominance of the lower class, which is distributed by 172 (58.1%) sectors of the sub-basin surveyed. However, it is necessary to invest in improving socioeconomic indicators and reducing Criticality and maintaining Support Capacity. |

Dessa forma, o objetivo da pesquisa foi analisar a vulnerabilidade socioespacial da Sub-bacia Hidrográfica do rio Piracuruca à ocorrência de secas e inundações. A Sub-bacia está localizada entre os estados do Ceará e do Piauí, drena uma área de 7.704 km2 e apresenta-se bastante heterogênea, tanto do ponto de vista biofísico quanto socioeconômico. Ao estudo foi aplicado modelo de estatística multivariada Análise Fatorial (AF) e método de estimação Análise das Componentes Principais (ACP), a partir do emprego de variáveis – demográficas, de infraestrutura, de saneamento básico, naturais, econômica e social da população – considerando os 296 (duzentos e noventa e seis) setores censitários, do censo demográfico de 2010. Destaca-se que a partir desse método/modelo e integração dos elementos Criticidade (características e comportamento da população) e Capacidade de Suporte (infraestrutura) foi possível a construção do índice de vulnerabilidade socioespacial (IVSE) da Sub-bacia do rio Piracuruca. Desse modo, as variáveis utilizadas para conhecimento da Criticidade apontaram que em 87 (29,4%) setores da Sub-bacia predomina a classe alta. Por sua vez, inferiu-se por meio da Capacidade de Suporte que 137 (46,3%) setores da Sub-bacia encontra-se na classe muito alta. Entretanto, o índice de vulnerabilidade socioespacial indicou a predominância da classe baixa, que se distribui por 172 (58,1%) setores da Sub-bacia pesquisada.Contudo, é necessário realizar investimento para melhoria dos indicadores socioeconômicos e redução da Criticidade e manutenção da Capacidade de Suporte.Universidade Federal de Uberlândia2020-05-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/4916010.14393/SN-v32-2020-49160Sociedade & Natureza; Vol. 32 (2020); 321-334Sociedade & Natureza; v. 32 (2020); 321-3341982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/49160/28907https://seer.ufu.br/index.php/sociedadenatureza/article/view/49160/28908Copyright (c) 2020 Francílio de Amorim dos Santos, Maria Lúcia Brito da Cruz, Lúcia Maria Silveira Mendesinfo:eu-repo/semantics/openAccessdos Santos, Francílio de AmorimBrito da Cruz, Maria LúciaSilveira Mendes, Lúcia Maria2021-07-01T16:18:20Zoai:ojs.www.seer.ufu.br:article/49160Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2021-07-01T16:18:20Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
