“…In this study, the level of negative answers (54.4%) was high when compared to other studies in Brazil; Gullo (2010), for example, obtained 34.8% of negative answers for the preservation of a dam, and in the study of Silva and Lima (2004) on the preservation of the Chico Mendes Park, in Rio Branco, 32% of the responses were "zero". Similar results were reported by Saz-Salazar and Guaita-Pradas (2013), which had 52% of "zero" answers and by the study of Dziegielewska and Mendelshon (2007), in which more than 65% of the answers were "zero".…”

“…It is obtained by applying questionnaires in which people's preferences are evaluated (MITCHELL & CARSON, 1989). Econometric models are most commonly used in order to determine the willingness to pay (WTP), taking into account the respondent's profile characteristics, such as socioeconomic variables and other information related to the evaluated asset (SILVA & LIMA, 2004;MAJUMDAR et al, 2011;OLIVEIRA & MATA, 2013;LO & JIM, 2015). In the present work, environmental concern is introduced as an explanatory variable in the application of the CVM.…”

This paper estimates the value of environmental damage generated by pollution in the artificial lake Salto Caveiras, evaluating the willingness to pay (WTP) of the local population for its recuperation and conservation. Environmental Concern Scale (ECS) was introduced, in addition to the socioeconomic variables, collected by the Contingent Valuation Method (CVM) and modeled by Logit regression and evaluated by multivariate statistics instruments, utilizing Principal Components Analysis (PCA). We demonstrate that 45.6% of the interviewed are willing to pay monthly. The others answered negatively: 18.9% because of payment incapacity, 12.8% would donate a smaller value than the one proposed and 22.8% gave a protest response.. The introduction of ECS as a new variable to CVM is significant as a unique and innovative variable provided by multivariate analysis indicated to be promising, what recommends such procedures to other studies.Keywords: environmental concern; multivariate analysis; valuation economic; water resource; water pollution. RESUMOO objetivo deste trabalho foi estimar o valor dos danos ambientais gerados pela poluição ao lago artificial Salto Caveiras, a partir da mensuração da disposição a pagar (DAP) da população local pela recuperação e conservação do mesmo. Foi introduzida na análise uma Escala de Consciência Ambiental (ECA), além do perfil socioeconômico, obtidos com a aplicação do Método de Valoração Contingente (MVC) e modelados pela regressão Logit e avaliados por instrumentos da estatística multivariada, utilizando-se da Análise de Componentes Principais (ACP). Os resultados revelam que 45,6% dos entrevistados estão dispostos a contribuir. Os outros responderam negativamente: 18,9% devido à incapacidade de pagamento, 12,8% propuseram um valor menor do que o sugerido e 22,8% deram uma resposta com caráter de voto de protesto. A introdução da ECA como uma nova variável ao MVC se mostrou significativa, bem como a visão holística, inédita e inovadora proporcionada pela análise multivariada se mostrou promissora, recomendando-se tais procedimentos para outros estudos.Palavras-chave: percepção ambiental; análise multivariada; valoração econômica; recurso hídrico; poluição da água.

“…Mattos et al (2007) reported that as income rises, WTP is likely to increase as well, indicating that people with a higher income demand improvements in environmental quality. In contrast, both Mattos et al (2007) and Silva and Lima (2004) found no signifi cant relationships between education and WTP.…”

Valuation of the Aroeira (Myracrodruon urundeuvaAllemão ABSTRACT(Valuation of the aroeira (Myracrodruon urundeuva Allemão): Perspectives on conservation). Assigning an economic value to a given environmental asset has helped conservation proposals, and valuing these assets at levels comparable to market rates facilitates the establishment of environmental policies. Th us, this research aimed to assess the value of the species Myracrodruon urundeuva Allemão, using the method of contingent valuation to determine the maximum willingness to pay of frequent visitors to the Caruaru Fair, located in northeastern Brazil. Our results show that most interviewees agreed to participate in proposals to support species conservation, although the average willingness to pay (WTP) was relatively low compared to other surveys conducted in Brazil. However, a signifi cant number of the interviewees had exceptionally low monthly incomes. Another relevant aspect of this research was the high number of people (98.5% of the informants) who were concerned about biodiversity conservation; many interviewees stated that the preservation of biodiversity is not a duty exclusive to the government or the people but rather a collective responsibility. Th erefore, these fi ndings may encourage the provision of public proposals for environmental conservation, along with other surveys or government actions funded by a society that has the willingness to pay for them. Th is study is the fi rst economic valuation of a caatinga species, many of which are under threat of extinction.

“…A estimativa da disposição a pagar foi baseada no modelo de perguntas oriundo do método de valoração contingente chamado "jogos de leilão", que consistiu em criar uma situação-problema e, baseado nela, o indivíduo daria o valor (lance) da sua disposição a pagar, frente às múltiplas alternativas (Hildebrand et al, 2002;Silva & Lima, 2004;Morgado et al, 2011). O método foi escolhido por ser eficiente na definição entre dispostos e não dispostos a pagar, sendo este um modelo ideal de perguntas para o tipo de estudo (Tabela 1).…”

“…O problema nesse tipo de concepção reside no fato de que essa postura representa um distanciamento da população em relação à maneira como o parque vem sendo gerido e isso influencia diretamente na qualidade de vida da sociedade atual e das futuras gerações, como destacado por Silva & Lima (2004).…”

Avaliação Ambiental do Parque Olhos D’Água: Aplicação do Método da Disposição a Pagar

et al. 2017

RESUMOO objetivo do estudo foi o de aplicar o método da Disposição a Pagar (DAP) aos frequentadores do Parque Olhos D' Água e, com isso, contribuir para a valoração dos seus atributos ambientais visando à preservação e melhoria da referida Unidade de Conservação. O Parque Olhos D' Água localiza-se em área nobre de Brasília e foi criado na esfera administrativa do Distrito Federal. O presente estudo apoiou-se em variáveis de segmentação econômica, psicográfica e no conhecimento ecológico dos usuários. Para tanto, foram aplicados 100 questionários, contendo perguntas divididas em duas partes: 1) indicação da disposição a pagar pelos usuários do parque; 2) segmentação, segundo determinados critérios e caracterização dos usuários. Os resultados indicaram não somente que as pessoas com perfil altruísta e mais preocupadas com o meio ambiente apresentaram maior disposição a pagar pela conservação do Parque Olhos D' Água, como também que este segmento de usuários poderia contribuir para a definição do perfil do usuário verde e, com isso, servir de base para a elaboração de um programa de marketing ambiental orientado para o incremento dos recursos financeiros necessários para as ações de preservação e melhoria do referido parque.Palavras-chaves: valoração ambiental, marketing ambiental, gestão ambiental. Environmental Assessment of the Olhos D' Água Park: the Method of Willingness to Pay ABSTRACTThe aim of the study was to apply the method of Willingness to Pay (WTP) to users of the Olhos D`água park in order to contribute to the valuation of its environmental attributes aiming at preservation and improvement of the Conservation Unit. The Olhos D' Água park is located in a prime area of Brasília administratively created by the Federal District. This study was based on economic and psychographic segmentation variables and on the ecological knowledge of users. To this end, 100 questionnaires were applied with questions divided into two parts: 1) indication of willingness to pay by users of the park, and; 2) segmentation, according to specific criteria and characterization of users. The results indicated not only that people with altruistic profile and more concerned with the environment showed a greater willingness to pay for conservation of the Olhos D´água park, but also that this segment of users could contribute to the definition of green user profile and, thus, serve as a basis for the elaboration of an environmental marketing program geared to increase the financial resources for preservation and improvement of the park.
