Crise da cafeicultura e seus efeitos socioeconômicos no município de Dracena (SP)

The coffee crisis in the 1980s reached deeply municipality of Dracena, considering that the coffee had significant social and economic importance to the area. In this context, the research aimed to analyze the socioeconomic consequences that this crisis has provided small rural proprietors of the county. To achieve this goal we seek to articulate the theoretical reference, with data from secondary sources, interviews with the main responsible for the agricultural sector and an application questionnaire to 21 small rural proprietors of the county. It was found that, due to the dependence relationship with the coffee, the economy of the city suffered from the attack of said culture during the 1980s. Rural producers who cultivated such crops as the main, had to readjust productively to remain in the countryside, but the economic and social development that coffee was brought in earlier times was not rescued. As a consequence, there has been an intensification of evasion demographic of rural municipality, a process that had begun in the 1970s and was strongly reinforced by the crisis of the coffee culture. We note that from the 2000s, the situation became better for small rural proprietors in order that public policies implemented now serve, in part, the needs of those with greater efficiency. This situation can be evidenced by a slight reduction in the number of rural people dracenense. Despite improvements recorded since the 2000s, the situation is still not ideal, given that many small proprietors surveyed expressed dissatisfaction. In this context, we note that the performance and joint of federal, state and municipal government are essential so that public policies are efficient, thus providing decent conditions for social reproduction of small rural proprietors and their dependents in the countryside

A precarização do trabalho: migrantes nordestinos no município de Leme-SP : caminhos, estradas e sonhos

This paper aims to examine the genesis of migration to the city of Leme-SP, as well as the influence of the social matrix northeastern expansion and redevelopment through the territorialization of the migrant population, particularly workers from the state of Ceará, migration from the 1970s. This process is evidenced by the territorial division of labor, through the economic, political and cultural insecurity through the work of cutting sugar cane, the territoriality of culture and northeastern faith in the city, and becomes another object before the materiality in which occurs.

A fisiologia da paisagem e as potencialidades turísticas ao longo do vale histórico da Serra da Bocaina-SP

The region encompassed by the cities of Bocaina’s Historic Valley has your formation closely linked to the coffee´s culture, that were installed during the nineteenth century bringing, at first, a great economic and population growth. However, with the time, the incorrect wear land of the area combined with the antislavery movement and the discovery of more fertile soils in western of São Paulo, among other factors, brought serious setbacks for coffee production in the region which ultimately migrate to other areas, causing an economic crisis in the region that endures to this day. Thus, this paper aims to conduct a study that part of an update of the concept of physiology landscape to identify the physical, ecological and social facts that make up the area of this region, to understand the real causes and consequences of the crisis and what potential persist to circumvent it

Análise de ocorrências dos impactos pluviais na área urbana de Rio Claro (SP)

The Urbanization is a notable process in our society, being part of it since around 3500 BC in Mesopotamia, currently Iraq area. Since the Industrial Revolution, cities had a significant increase in their growth and began to concentrate increasingly labor and capital. Brazil, despite having had a late industrialization, also had a high population growth in cities, especially in the XVIII century, which were not provided with any kind of planning that targets the ordering and implementation of the urban essential apparatus. Therefore, Brazilian cities started to exhibit countless structural and environmental problems. Associated with inadequate infrastructure, the modifications in the urban atmosphere, like increased heat, air pollution and increased rainfall and storm frequency, cause different types of impacts in cities. Among the most worrisome are those from the intense rain, which cause human and material damage. The city of Rio Claro (SP) can be considered an example of this reality. Thereby, the objective of this study was to analyze the impacts on the population originated from rainfall in the urban area during the period 2005-2010, by the mapping of events and analysis of the active atmospheric systems. The information of the events were collected in the Fire Department and the Press and the synoptic maps were obtained in the library of INPE, in Cachoeira Paulista (SP) and in the site of the Navy of Brazil. The data showed that among 247 occurrences, during the six years, 233 occurred in the spring-summer period. Moreover, after finalizing the maps, it was found the locations considered critical regarding the frequency of occurrences, as: Visconde do Rio Claro Avenue and central area of the city, both with a total of 23 occurrences; Jardim Inocoop, with 20; Tancredo Neves Avenue, with 12 and Vila Paulista, with 10 occurrences. Through the graphs, it was found that the most recurrent atmospheric system, during the studied period, is...

A influência das características morfométricas e de uso da terra na morfodinâmica: um estudo da alta bacia do Rio Itanhaém - Baixada Santista/SP

Diante do desenfreado uso da terra, gerando impactos muitas vezes irreversíveis, o planejamento ambiental insere-se como uma ferramenta atualmente necessária. Visto que é sob o relevo que se consolidam as atividades antrópicas, a cartografia do relevo surge como um importante instrumento, indicando setores cujas características naturais impõem limites ao uso da terra. Assim, o objetivo desta pesquisa é analisar as características geomorfológicas da alta bacia do Rio Itanhaém, com ênfase à questão morfográfica e morfométrica do relevo, avaliando também as modificações impostas a este em decorrência do uso da terra, contribuindo, portanto, com a gestão ambiental desta área. Para tanto, foram elaborados documentos cartográficos capazes de evidenciar as características do relevo que impõem limites ao uso antrópico, a saber: as cartas morfométricas (carta de declividade, carta de dissecação vertical, carta de dissecação horizontal e carta de energia do relevo), que são documentos que evidenciam a suscetibilidade potencial do relevo sob a influência da ação das águas e gravitacional; a carta geomorfológica (cenário de 1962), que possibilita a espacialização das formas do relevo, contribuindo para a análise da morfodinâmica; e as cartas de uso da terra (cenário de 1962 e 2000), que, em conjunto com os documentos já especificados, possibilitam a análise da influência da atuação antrópica sob o sistema relevo. De maneira geral, pôde-se detectar problemas na morfodinâmica da área de estudo, evidenciados pela presença de feições denudacionais localizadas, tais como sulcos erosivos, voçorocas, ravina e cicatrizes de escorregamentos, os quais vinculam-se ao potencial natural que o relevo da área de estudo possui ao desencadeamento de processos morfogenéticos; à dinamização de processos naturais pela atuação antrópica...

Análise do conforto térmico da cidade de Mirandópolis/SP em seus espaços abertos

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

Um estudo sobre aspectos da gestão dos resíduos sólidos no município de Ribeirão Preto (SP)

Since the beginning of it’s existence the humankind coexists with the production of waste, both organics and inorganics. Over the years the world population is raising, and consequently the different kinds of waste, causing significant problems not only for the public authorities, but also for the population, not only those related with its final or temporary destination but also with its crescent production. Considering it, the cities are not able to handle there volumes, and its landfills and dumps are working over their capacities, leading to a serie of environmental problems due to the lost of environmental quality and the natural and social vulnerabilities arising. This paper plans to working over visits, photographic registration and a review on the theme literature, study the perception and valuation of the landscape on the Ribeirão Preto landfill, São Paulo state (SP), that today is disabled but still an area of risk and environmental vulnerability, well as the perception of environmental quality in the surrounding population

Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem

Avaliação do método de classificação baseada no objeto em imagens de alta resolução espacial aplicado para o monitoramento de faixa de dutos: estudo de caso no entorno da refinaria de Capuava em Mauá - SP

The metropolitan region of São Paulo is the most populous of the country, this happens because of its great importance in the national economy and the job opportunities that are offered to the population. These factors result in intense population growth and urban expansion, reaching some non-habitable places of the metropolis, as areas of pipelines, which are very important for the transportation of natural gas, oil and its derivatives. Before the population growth of the region, these sites were unoccupied, do not presenting problems for the population. However, with the disorderly occupation is generated great anthropogenic pressure on the pipeline stitches, causing risks to people who are around them. Therefore it is extremely important to monitor the strip of pipelines through products and techniques of remote sensing and geoprocessing, enabling, through high spatial resolution images, identification of objects or phenomena that occur on Earth's surface that can alter the functioning and safety of pipelines. Therefore, this study aims to monitor a stretch of the area of the pipeline mesh GASPAL/OSVAT and Capuava Refinery (RECAP), located on the outskirts of the metropolitan area of São Paulo in the city of Mauá, who suffer great human pressure, proving thus the techniques of remote sensing and geographic information system (GIS) as effective tools for monitoring phenomena occurred in urban areas of great complexity. The monitoring was done by object-based classification applied in orbital images Ikonos II and RapidEye, of high spatial resolution and, image processing, detection of objects, segmentation, classification and editing were developed through the eCognition and ArcGis softwares. To determine the statistical accuracy of the mapping of the land cover of the stretch of pipeline in Maua, the results were analyzed by error matrix...

Impactos pluviais na cidade de Presidente Prudente-SP

Os eventos extremos pluviométricos quando ocorrem em cidades sem um prévio planejamento capaz de suportar tais episódios, trazem certo desconforto para a população e seu habitual modo de vida. Os impactos registrados nos ambientes urbanos estão associados, na maioria das vezes, à inadequação do uso e ocupação do solo urbano. Assim, através deste estudo buscou-se analisar os impactos deflagrados por eventos de precipitação na cidade de Presidente Prudente, baseando-se principalmente no referencial teórico-metodológico Sistema Clima Urbano, em especial, no Subsistema Hidrodinâmico, proposto por Monteiro (1976). Assim, procurou-se analisar os transtornos que ocorreram na dinâmica socioambiental da cidade durante os eventos de precipitação mais expressivos. Para isto foram analisados os dados quantitativos da Estação Meteorológica da FCT/UNESP de Presidente Prudente e também dados qualitativos por meio dos registros dos jornais da cidade. Para as análises quantitativas foram utilizados os dados da estação meteorológica do período de 1969 a 2009, e para as análises qualitativas foi considerado este mesmo período. Através desse estudo, foi possível conhecer e estudar a distribuição espacial dos problemas sociais e ambientais deflagrados pela precipitação no ambiente urbano de Presidente Prudente e também entender a dinâmica desses impactos. Portanto, com este estudo pretende-se contribuir com os órgãos públicos de gestão urbana para que eles possam tomar medidas preventivas para diminuir os impactos em época de chuvas intensas, visando assim, à melhoria da qualidade de vida

Mapeamento do uso da terra como subsídio a um plano de recuperação das áreas de preservação permanente no entorno da represa de Salto Grande - Americana - SP

Currently, the dam of Salto Grande is very degraded. Water quality is seriously amended, and lack of riparian vegetation, as well as the advance of feed crops and land occupation in areas that should be permanently preserved, only complicate this situation. The permanent preservation area is essential for the water sources protection, soil erosion control and consequent watercourse sedimentation. Through aerial photography, using GIS techniques, it was able to identify the outwards bounds of the dam, to demarcate the permanent preservation areas and generate maps for land use. With this data, in addition to studies and ideas of reforestation in different environments, the development of a plan for restoration of degraded areas surrounding the dam is easier to be done. This study confirmed that about 72% of land use in permanent preservation areas is not in accordance with specific laws, making necessary its recovering.

Avaliação das taxas de erosão química e física na bacia hidrográfica do Ribeirão Jacutinga (SP)

Currently with the growing technological advancement and global, new areas are being devastated, and as a result, the erosion became more frequent causing loss of soil, infiltration capacity of the surface and weathering of rocks.
