Resumo: | The Carahá River is one of the main urban rivers of Lages, Santa Catarina, Brazil, whose water quality is compromised by the inadequate disposal of sanitary sewage and household waste. Avenues surround its banks, and often overflow occurs affecting the riverine population. The objective of this study was to estimate the environmental value given by the population of Lages for its preservation through the application of the contingent valuation method (CVM), as well as to evaluate the differences in environmental perception considering the stratification of people according to its relation or influence with the evaluated environmental resource, considering its geographic location. Data were collected through the application of questionnaires using the referendum method and analyzed by logit regression and principal component analysis (PCA). The results show negative willingness to pay (WTP) for 61% of the interviewees, with 48% being characterized as a “protest vote”. The value of the individual benefit estimated by the logistic regression was R$ 2.95, considering the entire sample, and R$ 20.18, when the protest votes were removed, indicating strong influence of the protest votes in the results. The PCA was adequate and provided a more holistic view, especially when the aim is to compare different social groups that make up the sample. |

Avenidas contornam suas margens e, frequentemente,ocorre o transbordo, afetando a população ribeirinha. Em função dessaproblemática, o presente trabalho objetivou estimar o valor ambiental dado pelapopulação de Lages para sua preservação, por meio de aplicação do métodode valoração contingente (MVC), bem como avaliar as diferenças de percepçãoambiental considerando a estratificação das pessoas de acordo com a suarelação com o recurso ambiental analisado ou a influência deste no seu dia a dia,considerando sua localização geográfica. Os dados foram coletados mediantea aplicação de questionários utilizando-se o método referendum e analisadospor regressão logística (logit) e pela análise de componentes principais (ACP).Os resultados demonstram disposição a pagar (DAP) negativa para 61% dosentrevistados, sendo que 48% foram caracterizados como um voto de protesto.Os valores do benefício individual estimados pela regressão logística foram deR$ 2,95, considerando toda a amostra, e de R$ 20,18, quando foram retiradosos votos de protesto, indicando forte influência destes nos resultados. A ACPmostrou-se adequada e proporcionou uma visão mais holística, sobretudoquando se deseja comparar diferentes grupos sociais que compõem a amostra.Zeppelini Publishers2018-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/7110.5327/Z2176-947820180272Revista Brasileira de Ciências Ambientais (Online); n. 47 (2018): RBCIAMB - ISSN 2176-9478 - Março; 116-129Brazilian Journal of Environmental Sciences (Online); No. 47 (2018): RBCIAMB - ISSN 2176-9478 - March; 116-1292176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESporhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/71/46Copyright (c) 2018 Revista Brasileira de Ciências Ambientaisinfo:eu-repo/semantics/openAccessMombach, Gabriel Nathan NicolaWahrlich, JúliaClauberg, Ana Paula CoelhoBeninca, Lucas SilveiraSimioni, Flavio José2022-06-25T22:11:09Zoai:ojs.www.rbciamb.com.br:article/71Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2022-06-25T22:11:09Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false |
