O presente trabalho teve o intuito de resgatar o fenômeno ocorrido em agosto de 1986, no município de Cajamar, onde ocorreu o primeiro caso de formação de dolinas de subsidência e colapso no Brasil em área urbana. Mostra-se assim, através de interpretações da Fisiologia da Paisagem do local atingido, o modo que a cidade se reorganizou após o impacto, tanto na questão ambiental, como nas questões sociais e urbanas, através de entrevistas, relatando o modo de vida e as condições que se encontram a população e o local atingido neste episódio, sendo constatada então, a estabilidade do solo na área em questão

The city of Guaratinguetá, SP, presents in its history, several instances of property damage and human losses, conditional on the event of flooding and mass movement of soil, resulting from the development of erosion processes. The extent and severity of these events that affect humans and their properties is the result of the illegal occupation of these areas as potential geohazard. Thus, it is of great importance to physical characterization and identification of such areas within the map of the same city as a way to minimize the effects and mitigate the consequences of these events. Thus, this graduate report presents a series of field campaigns, geotechnical laboratory testing, consultation with maps and satellite images, representative of the physical environment, and the city plan as a means conclusive for the delimitation of risk areas with potential for occurrence of erosion and / or flooding on the map representing the urban area of Guaratinguetá, SP. Also featured are the descriptions of the main characteristics of those areas identified as being at risk, along with proposals to avoid or minimize the impact of problems related to flooding and erosion processes on the local population

Localizada no centro-oeste do Estado de São Paulo, Bauru é considerada uma cidade de médio porte. Possui aproximadamente 360 mil habitantes (estimativa da população em 2009, segundo o IBGE), e com isso, apresenta diversos problemas relacionados à mobilidade urbana e ao planejamento urbano, tais como: trânsito intenso em determinadas vias, calçadas em mau estado de conservação, falta de incentivo aos meios de transporte mais sustentáveis – modos não motorizados (a pé e bicicletas) e transportes coletivos. Este Trabalho Final de Graduação propõe a requalificação urbana em uma das principais avenidas que da cidade de Bauru, a Nações Unidas. Este projeto tem maior destaque nos usuário de transportes não motorizados, incentivando assim, a maior utilização desses modos no cotidiano dos cidadãos

El objectivo del trabajo fue analisar los impactos ambientales y sociales de las politicas publicas y de la especulación imobiliária sobre las áreas remanescientes de la vegetación nativa en la Granja Carolina. Con base en la definición del Património Cultural y Património Natural, fue abordado el proceso de formación desa región oeste de la metrópole, especificamente en lo entorno de la Granja Carolina situada entre los municipios de Cotia y Itapevi. La identificación deses problemas y la realización de un estudio sobre el modelo de la ocupación y el uso de lo solo urbano permitiu identificar su grau de vulnerabilidad a los impactos traydos por la expansión urbana. Para lo entendimiento de tais cuestiones analisamos lo proyecto y lo EIA/RIMA de um empreendimiento imobiliario que si pretendia instalar em la área de estúdio. Entendese también que el planejamiento territorial debe conter el debate sobre la protección del Património Cultural y Natural, cuestiones también pertinentes em el campo de la Geografía

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

This paper proposes an analysis of two major polluting elements of the atmosphere of São Paulo city, carbon monoxide (CO) and sulfur dioxide (SO2). This study was performed through analysis of data on the quality of air, by means of published reports and records obtained by experiment using measuring rate monitor for CO2. Atmospheric data were collected and sorted. From this work it was possible to identify the concentration of carbon dioxide in the center of São Paulo on September 14, 2012 using the infrared gas analyzer (IRGA). From the ratios of carbon monoxide and sulfur dioxide spatially analyzed could identify major emitters by comparing records of pollutants and their origin. The analysis makes it possible to map the intensity of air pollution in urban areas, identifying the polluting elements, their issuers and thereby contributes to the current understanding of atmospheric features, bringing a geographical spatial analysis of air pollutants in São Paulo, contributing to awareness of vulnerabilities, enabling a useful tool for planning and maintenance of the urban environment related public policies
