A ocupação humana desordenada e sem planejamento pode resultar em impactos ambientais como esgotamento do solo, perda de cobertura vegetal, erosão e perda de solo, assoreamento de leitos fluviais, contaminação das águas (superficiais e profundas), entre outros. Estas conseqüências estão presentes também no município de Ipeúna-SP, onde predominam as pastagens e o cultivo de cana-de-açúcar. Este quadro atual mostra a necessidade de se desenvolver estudos e levantamentos que contemplem diversos fatores ambientais (bióticos e abióticos) básicos para o entendimento das características, potencialidades e fragilidades da área, possíveis de subsidiar o planejamento e a gestão do uso da terra e adequar a utilização dos recursos naturais disponíveis com conservação do meio ambiente. O estudo da fisiografia permite a caracterização e classificação das paisagens terrestres levando em consideração os fatores formadores destas paisagens (clima atual e passado, hidrologia, geologia, geomorfologia e indiretamente aspectos bióticos) e as relações (processos) que os afetam. Desta forma, o objetivo da pesquisa foi investigar as características fisiográficas do município de Ipeúna-SP e, assim, contribuir para o melhor conhecimento dos aspectos do meio físico. Para atingir o objetivo foram realizadas as técnicas de interpretação de fotografias aéreas em escala 1:25.000, geoprocessamento e levantamentos de campo. A sistemática de trabalho adotada se resume a duas etapas: I) diagnóstico zero e; II) análise fisiográfica. O resultado final é o Mapa Fisiográfico em escala 1:50.000. A análise fisiográfica permitiu identificar e compreender os processos endógenos e exógenos que atuam e atuaram na evolução paisagem. O município de Ipeúna-SP é caracterizado por paisagens policíclicas de origem aluvial, coluvial/aluvial e estrutural... (Resumo completo, clicar acesso eletrônico abaixo)

The intensive development in the urbanization process implied a series of economic, social, and gradually, environmental transformations, essentially, since its intensification, which took place from the Industrial Revolution in Europe and North America. In Latin American countries, including Brazil, there was such acceleration in urban sprawl, only in the middle of the twentieth century, fomented by a peculiar industrialization, coming from the scientific-technical revolution, which occurred in developing countries. In this context, and with a lack of planning and an effective organization, cities of the dependent countries face an inordinate population growth and an unprecedented industrial swelling. Brazil, following this trend, presents several issues regarding the gaps in the provision of necessary infrastructure to meet the most basic needs of its population and the intense activity and anthropogenic effects on the environment. In this sense, environmental problems, related to air and water pollution, degradation and contamination of soil, paving roads, reduction of green areas, urban heat island, among others, reaching ever deeper into the Brazilian urban areas. It is important the analysis in this final project, the weather events related to episodes of strong winds and the events and the impacts to the population of Rio Claro (SP) in the period 2005 to 2010, basing themselves in Geographical Climatology and Urban climate studies. In this scenario, we found the prevalence of occurrences linked to falling trees in the study area, connected, at the same time, to the occurrence and to the absence of episodes of extreme events, with measurements of strong winds, showing a connection between the events and external facts to episodes of winds

As unidades de paisagens naturais se diferenciam pelo relevo, clima, cobertura vegetal, solos ou até mesmo pelo arranjo estrutural e do tipo de litologia. A caracterização pedológica e o entendimento das relações entre pedologia, geologia e geomorfologia são importantes para a compreensão da distribuição dos solos numa paisagem. Considerando esta como sendo uma combinação dinâmica e instável de elementos físicos, biológicos e antrópicos, e estando em constante evolução, realizou-se o estudo das características químicas, físicas, mineralógicas e morfológicas das coberturas superficiais de uma mesma Unidade Fisiográfica na região do Planalto Ocidental e da Depressão Periférica Paulista nas proximidades de Rio Claro – SP, para a compreensão de suas relações genéticas e cronológicas na evolução das paisagens da área. Para isso foram comparados os solos de dois transectos dentro dos compartimentos, levantando e analisando as características citadas para que se possa obter informações que permitiram o diagnóstico da evolução da área, visando contribuir para o avanço das coberturas superficiais e sua relação com a evolução da paisagem. Foi possível compreender determinados processos e produtos que deram origem às coberturas superficiais e consequentemente a algumas paisagens representativas da Quadrícula de São Carlos a partir dos métodos empregados. O estudo das coberturas de alteração intempérica da região centro-oeste paulista, e seu reconhecimento, são fundamentais para o ordenamento territorial e seu planejamento regional

Mirandópolis/SP appeared in 1934 from the railroad “the Brazil Northwest”, that there it served one of the points of its stretch that had as main function to drain the agricultural production northwestern native of São Paulo of that time. The installation of the town happened absent of concerns with initial urbanístico planning, thus modifying its natural landscape and modifying characteristic ambient without compensatory measures aiming at a future expansion of the urban mesh. Fact this that still causes today consequences the quality of life of the people and also the observed thermal comfort later. Ahead of this, the present work had for objective to identify through measurements of temperature and relative humidity of the city of Mirandópolis/SP the differences that in the fabric urban they corroborate for a comfort situation or thermal discomfort to the outdoors in accordance with the Diagram Bioclimático de Olgyay the collection of data was made throughout the month of July of 2011 involving the attainment of information of Temperature and relative humidity of air and questionnaire applied to the passer-bys in the act of the measurements. Also approaching the different thermal dynamic of the zones of housing in relation to the Urban Cannyon that develops the commerce as predominant activity. This research sample that, although a city to be small, the quality of life of its inhabitants is not only guaranteed by the transport or that its thermal comfort reveals inside homogeneous of the urban perimeter, but that it has yes heterogeneidade in the scope of the urban climate in these spaces

Este trabalho teve como objetivo principal analisar a dinâmica geomorfológica, bem como a apropriação humana do relevo, mediante a interpretação de forma integrada dos documentos cartográficos elaborados a partir de técnicas da cartografia morfométrica, geomorfológica e de uso da terra, de forma a subsidiar ações vinculadas ao planejamento ambiental da Bacia do Ribeirão Tijuco Preto (SP). Sob os auspícios da abordagem sistêmica, a partir de uma visão integrada e complexa dos sistemas geomorfológicos, propôs-se a quantificar os atributos das formas de relevo, representando-os cartográficamente com a elaboração das Cartas Morfométricas de Declividade ou Clinográfica (De Biase, 1970 e 1992), de Dissecação Horizontal (Spiridonov, 1981 e adaptações de Mauro et. al.,1991), de Dissecação Vertical (Spiridonov, 1981) e de Energia do Relevo (Mendes, 1993). Também, contemplou-se a cartografia geomorfológica de detalhe, com a elaboração da Carta Geomorfológica (Tricart, 1965), bem como o mapeamento do uso da terra, expresso na Carta de Uso da Terra (Ceron e Diniz, 1966). De forma geral, a análise dos Produtos Cartográficos elaborados, permitiu constatar que a Bacia do Ribeirão Tijuco Preto vem sofrendo o desencadeamento de processos erosivos variados. Tais processos estão associados a uma conjunção de condicionantes, que podem ser apontados pelas variadas condições morfométricas do terreno, o clima quente e úmido reinante, as diferentes litologias aflorantes, a tipologia dos solos, bem como, e, de maneira veemente, a intervenção humana. O condicionante antrópico está majoritariamente representado pela monocultura canavieira e pela urbanização, sendo agentes cruciais no desencadeamento dos processos erosivos existentes e na interferência direta na dinâmica do escoamento fluvial da Bacia do Ribeirão Tijuco Preto.

Air pollution is an environmental issue worldwide and frequently cause negative effects on population health and ecosystems on cities. The relationship between climate and atmospheric pollution can be used as a surrogate to the intensity of air pollution. The present and quantity of some gases can be used as indicators to air quality: particulate matter (PM), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2). Among those gases, CO has its major source within the cities, where automobiles are the main emitter. But measure pollutant concentration are challenging, sometimes because the lack of good equipments due to high costs and of the large variability of models that varies in precision, way of measure and distribution of sellers. Modeling are useful when there are an intend to evaluate air pollution, its sources and evaluate scenarios. This work aims to use CAL3QHCR model developed by the U.S Environmental Protection Agency (EPA) to generate predictive surfaces of CO concentration distribution on a site within Campinas city, located in São Paulo state, Brazil. CAL3QHCR model use data urban automobile circulation to generate spatial results for CO distribution. We observed that the pollution concentration was lower on our modeling than the concentrations measured by Companhia Ambiental do Estado de São Paulo (CETESB), the main environmental company on the São Paulo state. Also the correlation between average estimates of our model and the measure by CETESB was weak, indicating that the model used on this study need to be or better parameterized, or the scale we measured of CO emissions need to be rescaled. Although the model failed to correlate to CETESB data, maybe one that explore the estimated emissions distributed within the sites to understand spatial distributions of CO on the regions. Also, the generated information can also be used to other studies, and come to be useful to explain heat island

The knowledge of how animals deposited chemical components as water, protein, fat and ash in the carcass is importance for the formulation of a balanced diet, allowing maximum performance with a low environmental impact. So, the study was carried out to evaluate the influence of different tilapia strains (Chitralada, Commercial, Red and Universidade Federal de Lavras [UFLA]) on the deposition of bodily chemical components in the carcass. The bodily components analyzed were water, protein, fat and ash. For the determination of the bodily chemical deposition curves by age, the exponential, Brody, logistic, Gompertz and von Bertalanffy models were adjusted. The Commercial and UFLA strains deposited water at a faster speed (P<0.05) compared with the remaining strains. As for protein, the Red strain had a lower estimated maturity weight (49.37 g), and was more precocious (202 days) with regard to maximum deposition in comparison to the other strains (Chitralada, UFLA and Commercial) in which there was an estimated maturity weight of 231.5 g and maximum depositionfor 337 days. There were no differences (P>0.05) for the logistic model parameter between Red, UFLA and Commercial strains for fat, which presented a maximum fat deposition (0.23 g) at 310 days of age. Regarding ash deposition, the Commercial strain presented a higher maximum deposition (0.10 g) at 337 days, occurring later than the other strains that presented maximum deposition (0.033g) at 254 days of age. Thus, it was concluded that the genetic strains evaluated differ in chemical deposition curves of water, protein, fat and ash.
