    Abstract

    A Gruta do Maquiné, importante ativo ambiental do Município de Cordisburgo-MG, foi formada ao longo de milhares de anos pela natureza. Suas especificidades a tornam fonte de conhecimento e de geração de renda, sendo, portanto, essencial a sua proteção. A determinação do perfil do visitante da Gruta do Maquiné e a estimativa da demanda de visitantes são informações que podem contribuir para a tomada de decisão dos gestores desse ativo. Dessa forma, o objetivo geral deste trabalho consistiu em determinar o valor econômico do ativo ambiental Gruta do Maquiné - MG. Especificamente pretendeu-se: traçar o perfil do turista da Gruta do Maquiné, analisar a resposta dos consumidores às variações na taxa de admissão da Gruta do Maquiné e o excedente do consumidor por município e por indivíduo. As teorias que deram suporte ao estudo foram a de demanda e a de bens públicos, que fornecem o suporte necessário às metodologias de valoração econômica para a estimação dos “preços” dos ativos ambientais. O procedimento analítico usado foi o método do custo de viagem. Os dados foram obtidos por meio de questionários (298) aplicados aos visitantes da gruta no mês de julho de 2007. Os resultados obtidos demonstram que a maioria dos visitantes possui bom nível de escolaridade; em geral viajam acompanhados e visitam a gruta pela primeira vez. A disposição total média a pagar por visitas à Gruta de Maquiné, revelada pelos visitantes de cada região, foi R$ 80.654,81. Quando avaliado por indivíduos esse valor foi ainda menor, R$ 12.688,32, comparativamente àquele valor obtido por município. Concluiu-se, portanto, que os valores estimados não traduzem a real disposição dos indivíduos a pagarem por visitas à Gruta do Maquiné, visto que o valor de uso direto do ativo representa apenas uma pequena parcela do valor econômico total deste ativo ambiental. Mas se consideradas as restrições do valor encontrado, este pode fornecer um importante subsídio para a elaboração de projetos de conservação.--------------------------------------------------The Maquine Cavern, an important natural resource system located at Cordisburgo-MG, was built by nature in the last few thousand years. It is a source of knowledge to researchers and income to local people. Therefore, it is very important to preserve it. Visitors’ characteristics and econometric estimation of demand systems are key information which may be important to resource management decisions at local, state and federal levels. This study objective was to find the economic value of the Maquine Cavern. Specifically, the objectives were: a) To profile the Maquine Cavern visitor; b) To analyze the consumer surplus and the visitors’ response to variations in the admission fee by county; b) To analyze the consumer surplus and the visitors’ response to variations in the admission fee by consumer. The theory behind this study was the demand theory and public goods theory which support economic valuation methodologies to estimate natural resource “prices”. The analytical procedure was the Travel Cost method. Data were obtained by interviews (298) made with visitors in July 2007. Results showed that most visitors have high educational levels and generally do not travel alone and visit Maquine Cavern for the first time. Visitors which travel using their own cars show a high demand for visits and most visitors have monthly income between 2 and 5 minimum wages. The estimated Maquine Cavern average value with county data, i.e., the average willingness to pay for visits to the Maquine Cavern, revealed by visitors’ decisions in each county, was R$ 80.654,81. The average willingness to pay for visits to the Maquine Cavern, revealed by visitors when using individual data, was even smaller, R$ 12.688,32. The main conclusion was that estimated values do not show the real willingness to pay by individual for Maquine Cavern visits since the estimation of use values which represents a small part of total economic value of this natural resource.
