Proposição de índice de qualidade ambiental de vida municipal /

Silva, Wanderlei Sergio da. January 2006 (has links)
Orientador: Leandro Eugênio da Silva Cerri / Banca: José Bueno Conti / Banca: Antonio Manoel dos Santos Oliveira / Banca: Maria Inez Pagani / Banca: Fábio Augusto Gomes Vieira Reis / Resumo: Adotando a premissa básica de que a sociedade depende, para o seu bem estar, de bons indicadores relacionados aos fatores ambientais em seu sentido amplo, esta Tese analisa o significado dos termos qualidade ambiental e qualidade de vida sob o ponto de vista das Geociências e da ciência ambiental e propõe um novo índice que busca contemplar tais fatores de um modo mais abrangente, integrado e representativo da realidade. Para isto, discute o processo de formação da idéia sobre qualidade ambiental de vida, balizando-se em conceitos oferecidos por diversos estudiosos das questões que nela se incluem e destaca os principais indicadores que servem de parâmetros para a qualificação ambiental da vida, seu objeto precípuo, culminando na definição do Índice de Qualidade Ambiental de Vida IQAV, que pretende refletir a real situação dos locais objetos de sua aplicação. A Tese destaca o papel do adensamento humano como fator de queda da qualidade ambiental de vida, uma regra para todo lugar onde se pretenda aplicar este índice, e a necessidade de desenvolvimento de novas pesquisas nas áreas das Geociências e das Biociências para a efetiva aplicabilidade do índice proposto de um modo ideal. / Abstract: Adopting the basic premise that the well-being of society depends on positive indicators related to environmental factors in the broadest sense, this Thesis analyzes the significance of the terms environmental quality and quality of life from the perspective of the Geosciences and environmental science, and proposes a new index which seeks to take into consideration such factors in a more comprehensive fashion, integrated with and representative of reality. With this in mind, it discusses the process of the formation of the concept of environmental quality of life, with reference to concepts offered by various researchers into such questions, and focuses on the principal indicators which serve as parameters for environmental qualifications of life, its primary objective, culminating in the definition of an Index for Environmental Quality of Life IEQL (Indice de Qualidade Ambiental de Vida IQAV), which intends to reflect the actual situation in each local regarded as a focus of its application. The Thesis emphasizes the role of population density as a factor in the loss of environmental quality of life, a constant for each local where the Index might be applied, and the necessity for the development of additional research in the areas of Geoscience and Bioscience for the effective application of the Index as proposed in an ideal manner. / Doutor

Análise comparativa de técnicas de recuperação ambiental em áreas degradadas no município de Bofete/SP /

Castelli, Karen Regina. January 2014 (has links)
Orientador: Alexandre Marco Silva / Banca: Henry Lesjak Martos / Banca: José Mauro Santana da Silva / Resumo: As áreas usadas para plantio de espécies florestais comerciais que foram submetidas às atividades de recuperação ambiental ainda constitui um cenário raro no Brasil e muito pouco se sabe em termos de indicadores ecológicos destas áreas após o início do processo de recuperação, especialmente sobre os aspectos forísticos, edáficos e climatológicos. Desta forma, compararam-se indicadores ecológicos em três áreas submetidas e diferentes métodos de recuperação ambiental (transposição de solo (TS), poleiros artificiais (POL) e bosque abandonado de eucalipto (EUC) e uma área com vegetação nativa utilizada como referência (REF). As quatro áreas localizam-se numa propriedade rural no município de Bofete-SP. Em cada área levantou-se informações sobre os atributos fitossociológicos, edáficos e microclimáticos. O solo é de textura arenosa e com inexpressiva variação na composição granulométrica e grau de compactação entre as áreas de estudo. Os parâmetros químicos indicaram fertilidade significativamente baixa nas áreas POL e REF, sendo o solo de área EUC, o mais fértil. Foram identificadas 50 espécies arbóreas, sendo 29 espécies na área REF, 28 na área EUC, 8 na TS e 7 na POL. Apenas uma espécie foi comum a todas as áreas de estudo (Siparuna guianensis). O índice de Shannon variou em 1,05 (REF), 1,17(EUC), 0,65 (TS) e 0,58 (POL). O índice de Jaccard foi maior que 50% apenas na comparação entre as áreas REF e EUC, demonstrando baixa similaridade entre a composição florística das áreas. Observou-se que as áreas onde os valores de incidência luminosa e velocidade do vento foram maiores (POL e TS), exibiram menor diversidade florística, sendo essa composta apenas por espécies de estágios iniciais de regeneração. Os métodos de recuperação TS e POL não evidenciaram até o momento, eficiência na recuperação das áreas degradadas. A ação mais promissora seria manter o bosque com... / Abstract: Areas used for cultivation of commercial forest plant species subjected to environment recovery activities have constituted a rare scenário not yet well established in Brazil. Little information is provided in terms of ecological indicators where the recovery process has started in such areas, specially about the floristic, edaphic and climatologic features. In this study, the ecological indicators have been compared in areas where has been applied three methods of environmental restoration (soil transposition (ST), aritificial perches (PER), and areas with native vegetation (REF). The four areas are located in a rural one in Bofete, state of São Paulo, Brazil. The data regarding phytosociological, edaphic and microclimatic attributes have been surveyed. The soil is sandy-textured with an inexpressive spatial variation of the particle-size distribution and degree of comparison on the soil. The chemical attributes have indicated fertility significantly low in the PER and REF, and the soil of the EUC plot has been the most fertile. It has been identified 52 plant species, with 29 species in REF area, 28 in EUC, 8, in ST and 7, in the PER parcels. Only one species has been common in all study areas (Siparuna guianensis). The Shannon index values are: 1.05 (REF), 1.17 (EUC), 0.65 (ST) and 0.58 (PER). The Jaccard index was higher than 50% between REF and EUC areas, evidencing low similarity among the floristic composition of such areas. It has been observed where the light incidence and wind velocity values were higher (PER e ST), the floristic diversity were smaller. The set of species has been mostly composed of species of initial stages of ecosystem regeneration. Up to now, the recovery methods ST and PER have evidenced low effectiveness in recovering the degraded areas. The most promising action might be to keep the eucalypts woodland alilve, selectively pruning them and keeping the wood and herbaceous understory in continous growth / Mestre

The environmental Kuznets curve case for the USA and the BRIC countries

Rashid, Shehryar 20 November 2009 (has links)
Previous literature on the Environmental Kuznets Curve has focused extensively on why or why not such a relationship is observed given specific scenarios. More recent literature has shifted attention towards factors that may explain differences in the distribution or threshold of the curve. The purpose of this paper is to determine why we witness different cutoff points for environmental improvement given the same dependent variable. For this analysis, the relationship between CO2 emissions and GDP growth is observed in the United States and the BRIC countries (Brazil, Russia, India and China) from 1981-2006. The results suggest that the standard for environmental improvement is lower for the BRIC countries compared with the United States. Factors that explain this are FDI inflow, share of production from different industries, share of energy from different sources, and overall incentives.
