Análise da expansão urbana da cidade de Piracicaba no período de 2006-2011

The fundamental objective of this research was analyzed the urban expansion’s process of municipality Piracicaba, it is located in the countryside of São Paulo state. The use and occupation of land by observing the social and environmental impacts related, including the Protection Permanent Area (PPA) of urban fringes according to the successive expansions of Piracicaba city in 2006, the publication year of the current city hall director planning, until 2011, when the approval of the eighth and most recent update of Piracicaba’s expanding the perimeter. The development of the study was conducted with the support of bibliographic, cartographic, considering maps and satellite images, further more field work. Thematic maps of the current urban expansion were created, urban voids and land use were developed, typifying the occupation according to the activities established thus through the analysis of land use through cartographic interpretation, as research in locus. To assist the research geotechnologies were used, both for production and for the interpretation of cartographic materials, specially in Geographic Information Systems

Análise geomorfológica do sítio urbano de São Pedro/SP: evolução urbana e alterações geomórficas

Este trabalho apresenta o resultado de estudo e análise do espaço urbano de São Pedro/SP para avaliar a interferência da urbanização nas mudanças geomórficas e na formação de feições associadas a processos erosivos lineares acelerados. A área de estudo localiza-se na porção centro-oriental do estado de São Paulo, distando cerca de 198 km da capital. Encontra-se limitada pelas coordenadas 22º30’ e 22º45’ de latitude sul e 47º45’ e 48º00’ de longitude oeste. (FACINCANI, 1995, p.4). Para atender ao objetivo proposto, foram realizados mapeamentos geomorfológicos e do uso da terra ao longo do processo histórico de expansão da área urbana do município, mais precisamente desde 1970 até o período atual, com base na proposta técnica de Tricart (1965) e Anderson (1979), respectivamente. Para isso, foram utilizadas fotografias aéreas de escala 1:25.000, 1:40.000 e 1:30.000, referentes respectivamente, aos cenários de 1972, 1988 e 2000. Para realização da análise integrada da dinâmica do uso da terra e das alterações geomórficas foi utilizada a “Teoria Geral dos Sistemas” como orientação metodológica, uma vez que uma das principais preocupações do geógrafo são os impactos ambientais e, conforme Christofoletti (1986), para compreender e executar ações preventivas e de recuperação do meio degradado, é necessário obter conhecimentos adequados desses processos, com base numa abordagem integrada do espaço, visando à compreensão do funcionamento e do equilíbrio da natureza integrados com as atividades humanas. Dessa forma, este estudo constatou que a expansão urbana de São Pedro foi uma das causas do surgimento e evolução das diversas voçorocas existentes na área de estudo. Ainda, por meio de...

Os ventos e seus impactos na área urbana de Rio Claro (SP) entre 2005 e 2010: um análise através dos jornais e dos boletins de ocorrência

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

Diagnóstico antropogeomorfológico em bacia hidrográfica urbana: o caso do Córrego do Jardim São João, Araras (SP)

Man can transform the nature according to their needs through technique which enables agriculture, cattle raising, constructions of buildings for housing, transport routes, etc. This action has brought significant transformations to the environment, and relief is one of the most changed elements, mainly at urban areas, which concentrates most of the Brazilian population. In these areas geomorphologic systems have undergone alterations in their flow of matter and energy by the action of man. Thus, it is possible o understand the action of man as geomorphologic action, nowadays, the tecnógeno, since the human action can interfere qualitatively and quantitatively in the input and output of these systems. The anthropic geomorphology has contributed to the analyses of the effects due to the urbanization at the form and at the geomorphologic process in the urban watersheds, indicating the transformations at the shape of the relief and the alterations due to the acceleration of the flow of matter and energy. From these questions, this study had the main diagnose the anthropogenic changes of the relief at the basin of Corrego do Jardim São João, Araras (SP), comparing two scenes, 1997 and 2006, through geomorphological mapping evolutionary in the area. The geomorphological feature altered at the basin are directly linked to the use of soil, mainly at the urban use, which caused effects in the relief at the studied area, making possible to define periods of the urban evolution and impacts caused by the urbanization. Among the changes it was found the decrease of the topographic breaks and at the riverbed channels, as the increase of the accumulation of the plain and riverbed terrace. The elaboration of a letter of the legal restrictions of the basin make possible to evaluate some of the environmental urban problems that occur, which are due to the occupation of the relief in the areas of permanent preservation that brings significant impacts to...

Desenvolvimento da malha urbana de Guaratinguetá e propostas de intervenção

The work consists of the historical city of Guaratinguetá, as well as data on their quality of life, economic development and population, transportation in Brazil and the transportation system of the city serving as a basis to support the development of the urban network. The urban fabric of the city was raised with plants of the city in different years, documents obtained by the Museum and Hall of Frei Galvão Guaratinguetá well to check the form of land use and growth drivers of the city over time. We studied also the main access roads to the city by focusing on an approach that has been the subject of a proposed urban intervention. A direct interview was performed and recorded with one of those responsible for planning the urban fabric of the city in order to gather information on the historical development, the future possibilities of interventions in the urban as well as problems encountered and other curiosities. Through the study it was observed that the urban grid Guaratinguetá developing a planned since 1970 and that the highlights of most cities in the Paraíba Valley. The work is grounded in concepts of sustainable city and also in quantitative and qualitative data from sectors responsible

Levantamento florístico da mata ciliar do Ribeirão Lavapés em uma área urbana do município de Botucatu/SP

As matas ciliares representam importante ecossistema na natureza, formando um ecótono entre o ambiente aquático e o ambiente terrestre apresenta elevada diversidade tanto da flora quanto da fauna sendo importantes corredores ecológicos para diversas espécies. Além da sua importância ecológica as matas ciliares apresentam importante papel na manutenção da quantidade e qualidade da água, essenciais para nossa sobrevivência. Para que projetos de conservação e recuperação das florestas ciliares ocorram com sucesso, trabalhos envolvendo a população através da educação ambiental são de grande importância, principalmente quanto se trata de corpos d’agua que atravessam a cidade como é o caso do Ribeirão Lavapés

Requalificação urbana em Luanda

O plano inicial é de desenvolver um projeto em uma área com 602.087,50 km2, em um dos bairros da periferia da cidade de Luanda capital de Angola. A idéia principal é de melhorar as condições de moradias, saneamento básico, acesso ao próprio bairro, acesso ao transporte, infra-estrutura urbana e outros. Chamaria este projeto como célula modelo em que futuramente poder-se-ia espelhar ou até mesmo reproduzir para outras áreas adjacentes. Será um projeto de parceria, entre governo, e entidades privadas ou até mesmo financiamento através dos bancos, e o principal objetivo é chegar a um projeto que funcione e que se possa aplicar futuramente. Com base no aprendizado sobre os planos diretores e instrumentos de gestão urbana, adquiridos durante o curso, se vai fazer um projeto adaptado ao sistema ou mesmo à legislação de Angola
