Valoração ambiental no uso do solo urbano: aplicação do método dos valores hedônicos - estudo de caso no centro de Florianópolis

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia Civil.Este trabalho apresenta uma aplicação do método dos valores hedônicos que é uma metodologia de valoração econômica do meio ambiente, para o uso do solo urbano. Esta metodologia de valoração se apoiará também na Engenharia de Avaliações, para medir a influência do meio ambiente no valor do imóvel residencial urbano. Para o desenvolvimento do método, foi selecionado o centro do município de Florianópolis, estado de Santa Catarina, região onde o desenvolvimento urbano foi intenso nos últimos anos. Uma das etapas mais importantes foi a pesquisa de mercado, com a coleta de informações sobre os imóveis e o reconhecimento da região através de observações in situ, para a localização das variáveis ambientais existentes. A essência deste trabalho foi determinar se existe um diferencial de preços entre os imóveis situados próximos a áreas verdes (parques, praças, etc.) e/ou locais onde as formas de poluição (sonora, atmosférica, etc.) são mínimas; e os imóveis situados em outros locais. Foi utilizado o método comparativo de dados de mercado, para mensurar o valor do uso associado ao meio ambiente. Concluiu-se que as variáveis ambientais são relevantes na formação do valor dos imóveis na região estudada

Geoprocessing and spatial analysis for identifying leptospirosis risk areas: a systematic review

Leptospirosis is a reemerging zoonosis caused by bacteria of the genus Leptospira sp. with global importance in the medical and veterinary fields, being responsible for about 59 thousand deaths each year in the world. The use of Geographic Information Systems (GIS) in the health sector is propitious and has been adopted by human and animal health professionals as an important tool in spatial analyses of health. The objective of this study was to conduct a systematic review on the geoprocessing and spatial analysis techniques adopted for mapping risk areas of human and animal leptospirosis. The articles were collected on scientific platforms by entering the following terms: SIG/GIS, leptospirose/leptospirosis, area de risco/risk area and distribuicao espacial/spatial distribution, and included in the study if they met the following criteria: a) publication in the period from 1998 to 2017; b) identification of risk areas and/or spatial distribution of leptospirosis as one of the research topics; and c) application of GIS in the methodology. As a result, we found 40 articles, published by 15 different countries, which adopted GIS for the spatial analysis and identification of risk areas of leptospirosis. Among these, only 45% (18) conducted an spatial statistical analysis. Brazil and USA had the highest numbers of publications, 16 and 7 articles, respectively. From 2007, the use of GIS and spatial analysis techniques, applied to the theme of this study, have been intensified and diversified, and 93% of the articles elected for this review were published from 2007 to 2017. The results point to a progressive interest of health professionals in applying these techniques for monitoring and conducting epidemiological analyses of leptospirosis, besides indicating a greater need for intersectoral integration between health professionals and others, in the use of spatial analysis and GIS techniques
