Região metrolitana da Grande Vitória: investigando correlações para integrar investimentos / Metropolitan Region of Grande Vitória: investigating correlations to integrate investments

Latussa Bianca Laranja Monteiro 05 May 2017 (has links)
Esse trabalho tem por objeto empírico de pesquisa a infraestrutura viária da Região Metropolitana da Grande Vitória, assumindo que a malha viária é em si definidora do urbano e que serve como aproximação à existência, ainda que potencial, das demais infraestruturas que conferem funcionalidade às aglomerações. O objetivo geral é contribuir para integração das políticas públicas de caráter territorial em busca da diminuição das discrepâncias internas de qualidade. Partindo desses pressupostos, sabe-se que o grau de conexão do sistema serve como parâmetro de análise da forma urbana, ensejando conjecturar que sua correlação com indicadores de qualidade de vida atuaria como proxy da distribuição de riqueza no espaço urbano. Assim, efetua descrições em dois sentidos: o primeiro relata a questão metropolitana, quadro mais amplo em que se insere a contribuição; o segundo trata de aportes teóricos de descrição do espaço urbano e investigação em centralidade topológica, com destaque para a Sintaxe Espacial ou Teoria Social do Espaço. A primeira descrição se desenvolve partindo brevemente do arcabouço histórico e normativo dos espaços metropolitanos brasileiros em que a heterogeneidade é a característica do conjunto. Cita as diferentes institucionalizações e importância nacional, que impacta até mesmo na assimétrica disponibilidade de dados para o planejamento. Nesse primeiro contexto, caracteriza-se a RMGV, as principais marcas territoriais de sua formação e o que permanece proposto para sua configuração futura, o percurso de seu modelo de gestão e as expectativas de ação integrada em atendimento à Lei n. 1.3089,Estatuto da Metrópole. A segunda linha de desenvolvimento parte da assertiva de que o planejamento depende de informações. Nesse segundo contexto, o trabalho lista esforços e fontes de pesquisa disponíveis, concluindo pela relevância dos dados Censitários do IBGE como base para elaboração de indicadores voltados à descrição das múltiplas condições dos espaços intrametropolitanos. Após análise, o Índice de Desenvolvimento Humano Municipal (IDHM) é selecionado como o indicador sintético utilizado para representar as diferenças internas na RMGV. O passo seguinte é introduzir os conceitos básicos associados às medidas de centralidade citando exemplos de sua aplicação na ciência de redes. Cita a teoria de grafos e a modelagem matemática subjacente aos cálculos. Na sequência, por meio da ferramenta computacional Depthmap, são calculadas medidas de centralidade topológica da rede viária principal. O grafo resultante é então georreferenciado, utilizando o sistema QuantumGIS, assim como a informação do IDHM por Unidades de Desenvolvimento Humano, menor espacialidade disponível. Os resultados são expressos por mapeamento das medidas de centralidade e do IDHM que possibilita [i] a investigação da correlação visual entre as variáveis e [ii] um exercício de correlação estatística. Ambos resultados apontam para uma correlação positiva, mas baixa,ainda assim permitindo indicar destaques na constituição futura da RMGV. Conclui-se que a correlação existe, mas não é suficiente para designar, incisivamente, aonde a integração de investimentos resultaria melhores efeitos na redução das diferenças urbanas. Para aprimoramento deste trabalho, parece ser necessário um estudo mais detalhado sobre a sensibilidade do modelo viário utilizado, bem como uma análise estatística mais sofisticada sobre os parâmetros e dados de entrada. / This work has for empirical research object the road infrastructure of the metropolitan region of Grande Vitória (ES), Brazil, assuming that the road network itself defines the urban space and serves as an approach to the existence, albeit potential, of other infrastructural networks that add functionality to the agglomerations. The general objective is to contribute to the integration of public policies at the territorial level, aiming the decrease of internal discrepancies of quality. Starting from these assumptions, it is known that a system\'s degree of connection serves as a parameter of urban form analysis, allowing one to conjecture that its correlation with quality of life indicators act as a proxy for wealth distribution in urban space. Thus, the work makes descriptions in two senses: the first relates to the metropolitan question, the broader framework in which the contribution is inserted; the second deals with the theoretical contributions of urban space description and research in topological centrality, with emphasis on Space Syntax or Social Theory of Space. The first description is developed starting briefly from the historic and normative framework of Brazilian metropolitan spaces in which heterogeneity is the characteristic of the set. It cites the different types of officialization and national importance, which impacts even on the asymmetrical availability of data for planning. In this first context, it characterized the RMGV, the main territorial marks of its formation and what remains proposed for its future shape, the route of its management model and expectations of integrated actions in compliance with Law n. 1.3089, Metropolis Statute. The second description starts with the assertion that planning depends on information. In this second context, the work lists efforts and available research sources, it concludes that IBGE\'s Census are the most relevant data base for indicators composition aimed at describing the multiple conditions of intrametropolitan spaces. After analysis, the municipal human development index (HDI) is selected as the synthetic indicator used to represent the internal differences in RMGV. The next step is to introduce the basic concepts associated with measures of centrality by citing examples of their application networks science. The work cites the theory of graphs and the mathematical modeling underlying the calculations. Then Depthmap, a computational tool, calculates the topological centrality measures of the main road network. The resulting graph is then georeferenced, using the QuantumGIS system, as well as the information of the HDI by Human Development Units, smaller spatiality available. The results are shown by mapping the centrality measures and the HDI enabling visual correlation investigation between the variables and [ii] a statistical correlation exercise. Both results point to a positive but low correlation, still allowing to indicate highlights in the future constitution of the RMGV. It concludes that the correlation exists, but it is not enough to indicate, incisively, where the integration of investments would have better effects in the reduction of urban differences. To improve this work, a more detailed study on the road model\'s sensitivity seems to be necessary, as well as a more sophisticated statistical analysis on the parameters and input data.

Transporte sobre trilhos na Região Metropolitana de São Paulo: estudo sobre a concepção e inserção das redes de transporte de alta capacidade / Rail Transit in the Metropolitan Area of São Paulo: a study about the conception and insertion of high capacity transit networks

Marcos Kiyoto de Tani e Isoda 15 May 2013 (has links)
O objeto desta pesquisa é a rede de transporte de passageiros de alta capacidade da Região Metropolitana de São Paulo - seus trens metropolitanos e seu metrô. Através do exame das políticas e planos recentes (1995-2012), buscou-se identificar os conceitos e métodos de planejamento que regeram a concepção das diversas versões dessa rede e interpretá-las no contexto maior do processo histórico de reprodução da sociedade brasileira, a acumulação entravada. Simultaneamente, foram estudados aspectos técnicos selecionados dos sistemas de transporte urbano de alta capacidade, visando a identificação de seus traços distintivos e dos principais critérios de escolha entre os mesmos. Ao fim, procurando sintetizar os conceitos e parâmetros técnicos estudados, é apresentada uma proposta de rede de alta capacidade para a Região Metropolitana de São Paulo, mas que se reporta a um contexto de planejamento urbano distinto do atual, em que as redes de transporte e infraestruturas urbanas, de modo geral, assumem plenamente seu papel na organização e qualificação do espaço social. / The subject of the following thesis is a high capacity passenger transit network for the Metropolitan Area of São Paulo - its metropolitan trains and subway system. Through the examination of recent policies and plans (1995 to 2012) we identified the planning concepts and methods that ruled the conceiving of the several versions of this network and interpreted it in the scale of the historical process of reproduction in the Brazilian society, that is, the hindered accumulation. Simultaneously we studied selected technical aspects of the high capacity urban transit systems, to reveal its distinctive features and the main criteria for selecting one or the other. By the end, in order to summarize the studied technical concepts and parameters, we presented one design proposal of a high capacity transit network for the Metropolitan Area of São Paulo, that relates to a context of urban planning, different than the current one, in which the transit networks and general urban infrastructure fully take its role in organizing and qualifying social space.

Initially developed countries realize these changes and subsequently developing countries. The changes in production patterns, especially with the crisis of Fordism, peripheral countries further accentuated the problems in the workplace. Flexible accumulation, in turn, was responsible for significant changes in the labor market at the periphery of global capitalism. This restructuring process, in Brazil, begun from the end of the 1980s and early 1990s, being more accentuated the impacts on the labor market in the poorest regions of the country, particularly the Northeast. In that sense, this thesis aims to evaluate the job market in the metropolitan areas of Fortaleza, Recife and Salvador in light of the transformation process in the production structures and labor market and its influences in the 2000s. The time frame are the years 2001-2008. Data are from the National Household Sample Survey - PNAD and were drawn from the study proposal developed by the Centre of the Metropolis. The study shows that the labor market of the three metropolitan areas continues to be affected by the restructuring process of the late twentieth century. It found high rates of unprotected busy at work is more precarious conditions of employment for non-whites, women, adolescents / young and old. We also highlight the high percentage of employed persons earning income up 1.00 minimum wage, and a large number of persons employed in the tertiary and tertiary non-specialist. With the picture observed in the three metropolitan areas you can see the major problems in the labor market that proliferate, especially in the metropolitan context of the Northeast, with characteristics similar to those observed in the literature that investigated the labor market in 1990 / As transforma??es econ?micas mundiais, do final da Segunda Guerra, elencaram mudan?as significativas nas estruturas produtivas e no mercado de trabalho em todo o mundo. Inicialmente os pa?ses desenvolvidos perceberam essas transforma??es e posteriormente os pa?ses em desenvolvimento. As transforma??es nos modelos de produ??o, sobretudo com a crise do fordismo, nos pa?ses perif?ricos acentuaram ainda mais os problemas no mundo do trabalho. A acumula??o flex?vel, por sua vez, foi respons?vel por transforma??es significativa no mercado de trabalho da periferia do capitalismo global. No Brasil assistiu-se a esse processo de reestrutura??o produtiva a partir do final dos anos de 1980 e inicio dos anos de 1990, sendo mais acentuando os impactos no mercado de trabalho nas regi?es mais pobres do pa?s, sobretudo o Nordeste. Nesse sentido, esta disserta??o tem como objetivo avaliar o mercado de trabalho nas Regi?es Metropolitanas de Fortaleza, Recife e Salvador ? luz do processo de transforma??o nas estruturas produtivas e no mercado de trabalho e suas influencias nos anos 2000. O recorte temporal utilizado s?o os anos de 2001-2008. Os dados s?o da Pesquisa Nacional por Amostra de Domic?lios PNAD e foram elaborados a partir da proposta de estudo desenvolvida pelo Observat?rio das Metr?poles. O estudo mostra que o mercado de trabalho das tr?s RMs continua sendo afetado pelo processo de reestrutura??o produtiva do final do s?culo XX. Constatou-se elevados percentuais de ocupados desprotegidos no trabalho sendo mais prec?rias as condi??es dos postos de trabalho para n?o brancos, mulheres, adolescentes/jovens e idosos. Destacam-se ainda elevados percentuais de ocupados auferindo rendimentos em at? 1,00 sal?rio m?nimo, al?m de grande contingente de pessoas ocupadas no terci?rio e terci?rio n?o especializado. Com o quadro observado nas tr?s RMs ? poss?vel perceber os grandes problemas no mercado de trabalho que se proliferam, sobretudo no contexto metropolitano do Nordeste, com caracter?sticas semelhantes ?s observadas na literatura que investigaram o mercado de trabalho nos anos de 1990

A mobilidade está vinculada aos aspectos socioeconômicos da população. A acessibilidade está relacionada ao uso do solo e a forma urbana, ambas envolvidas no processo funcional da cidade. Os moradores de bairros suburbanos, que utilizam o transporte coletivo, possuem sérios problemas de acesso às áreas centrais da cidade. Tais problemas surgem com maior intensidade quando se verificam as grandes migrações pendulares. A pouca infra-estrutura dos bairros, aliada à baixa renda da população, ocasiona sérios problemas de mobilidade e acessibilidade. Para realizar esta análise foi escolhido, como estudo de caso, o bairro Jardim São João, no município de Guarulhos, caracterizado pela escassez de equipamentos urbanos e por problemas de transporte público. Os dados foram obtidos por meio de entrevistas pessoais, realizadas no período de dezembro de 2002 a maio de 2003, em horário de pico, nos pontos inicial e final de duas linhas, o que permitiu uma escolha melhor dos entrevistados. Optou-se por entrevistar apenas moradores do bairro Jardim São João, ou seja, as pessoas que têm origem e destino no bairro e que tinham como destino o trabalho. A partir destes dados foi possível estimar o número de empregos atingidos por dia e por linha de ônibus. Conclui-se que os problemas relacionados a mobilidade e a acessibilidade não afetam, diretamente, a freqüência das viagens entre o Bairro São João e os centros de Guarulhos e São Paulo. Pode-se constar que há um descontentamento em relação ao tempo excessivo de espera nos pontos de parada e dos itinerários. Há também queixas em relação aos custos, segurança e conforto. Nota-se que os direitos dos moradores do bairro Jardim São João está abalado. A participação efetiva destes moradores, na vida social, política e econômica da cidade é prejudicada / Abstract: This research has the objective of analyze the mobility and accessibility for the public transportation. The mobility is related to the social economics aspects of the population. The accessibility is related to the use of the ground and urban shape, both involved in the functional process of the city. The people living in the suburbs, that use the public transportation, own a lot of serious problems to get to the main parts of the cities. These problems can be noticed by the migration seen to the main parts of the city the poor. Of some areas, plus the low income of the population, end up with serious problems of mobility and accessibility. To make this research it was chosen, as a case of study, the area called Jardim São João, in the county of Guarulhos, known by its lack of equipment's land by its public transportation problems. The dates were collected by personal interviews, realized from December 2002 to may 2003, in the rush time, from the initial to the final of the two lines, which allowed a better way for choosing the interviews; we opted by interview just the people living in the area called Jardim São João, therefore; people have their origin and destiny, in the area that they as a destiny. From those dates it was possible to estimate the numbers of jobs reached per day and per bus line. We come to understand that all of the problems related to the mobility and accessibility don't affect, directly in the trips between the area São João and others main parts of Guarulhos and São Paulo, we can see that the quality of trip is being damaged. Therefore, people living in these areas don't quit on commuting to downtown. Choose or are obligated to move in local ways. There is a not pleasant relation to the waiting time at the bus stop. They're also complaints about the costs, security and comfort. The right from the people living in the area Jardim São João is touched. The participation there, in the social life, political and economic of the city is damaged. / Mestrado / Transportes / Mestre em Engenharia Civil

Biological control as an integrated control method in the management of aquatic weeds in an urban environmental and socio-political landscape : case study : Cape Town Metropolitan Area

Stafford, Martha Louise January 2014 (has links)
Aquatic weeds transform and degrade the ecosystems which they invade, impacting various aspects of their surroundings ranging from the community level to disrupting important processes affecting ecosystem services. All of the major aquatic weeds of South Africa are found in the Cape Town Metropolitan Area. Landowners, whether private or public, are legally obliged to manage the listed invasive species through applying environmentally acceptable methodologies. This thesis provides an overview of the strategic management options, prevention, early detection, rapid response and eradication of new invasions, and containment and control species of established species. It discusses the different control methods available for managing aquatic weeds, namely mechanical, manual, chemical and biological, and the integration of different methods to improve their effectiveness. Although various studies have shown that biological control is the most cost–effective, environmentally-friendly and sustainable method, it is not yet fully integrated into weed management programmes in South Africa. In addition, the successes achieved in other parts of the world with the control of water hyacinth through biological control have not been repeated in the urban environment, despite the fact that South Africa has the highest number of biological control agents available for the weed. Urbanisation puts pressure on the natural environment and ecosystem functioning. Nutrient-enriched waters support aquatic weed growth and pose a challenge to the management thereof, in particular with regard to integrating biological control into management programmes. The aims of this study were to determine the reasons for the lack of integration of biological control into weed management programmes in South Africa, to determine the feasibility of integrating biological control in aquatic weed management programmes in a complex urban environmental and socio-political landscape by means of three case studies in the Cape Town Metropolitan Area, which showed that biological control is feasible in urban environments and should be considered. Two surveys were conducted to determine the reasons for the lack of integration of biological control into weed management programmes. The surveys showed that there is a gap between research and implementation as a result of poor communication, non-supporting institutional arrangements and a lack of appropriate capacity and skills at the implementation level. Recommendations were offered to address these issues.

Vývojová typologie nejrychleji rostoucí části metropolitních USA v desetiletí mezi roky 2000 a 2010 / The Developmental Typology of the Fastest Growing Portion of the Metropolitan USA in the Decade from 2000 to 2010

Kohl, Ondřej January 2011 (has links)
This text was written as a diploma thesis of master's degree study course "Regional and political geography." It focuses on the development between the last two censuses, of the fastest growing metropolitan areas in the United States. The economic crisis of the late 2000s has been a major turning point of the decade. The goal of the research was to create a developmental typology of the fastest growing metros. The text analyzes "classifiers" data in order to decide what developmental types have been among the metros. A major factor contributing to high population gains in the fastest growing metros was the migration induced by the housing bubble.

Towards the integration of the historical and structural theories of urban form

Martin, David Tilford 01 January 1975 (has links)
In this thesis we examine the effect which the obsolescence of central city housing exerts on the decentralization within urban areas of high status residents. In particular, we investigate whether housing obsolescence is a useful addition to a model which explains the decentralization of high status residents in terms of the intensity of competition for central city land. All of our data are official Census figures for 1970. The subjects of our study are Standard Metropolitan Statistical Are.as (SMSA.'s) whose central city had a population of 100,000 or more. From this group we delete the New York and Chicago Consolidated Areas because of their great size and the number of municipalities included within their borders. For each SMSA we compute the percentage of its families and unrelated individuals who had an income of greater than $25,000 and who lived in the central city. We then statistically control for variation across SMSA.'s in the decentralization of population and employment. The decentralization of population is measured by the percentage of the SMSA population which resided within the central city. The decentralization of employment is measured by the percentage of SMSA jobs which were located within the central city. Once we have controlled the decentralization of the well-to-do for the decentralization of population and the decentralization of employment, we regress it on population density, housing obsolescence, and city age. Population density is persons per square mile in the central city. Housing obsolescence is the percentage of the central city housing structures which were twenty years old or older. City age is the number of decades since the central city attained a population of 50,000. In our study we demonstrate that population density exerts a considerably stronger effect on the decentralization of the well-to-do than is exerted by housing obsolescence. We also demonstrate that most of city age's effect on the decentralization of the well-to-do can be explained by city age's effect on population density and housing obsolescence.

Assessing Working Models' Impact on Land Cover Dynamics through Multi-Agent Based Modeling and Artificial Neural Networks:  A Case Study of Roanoke, VA

Nusair, Heba Zaid 30 May 2024 (has links)
The transition towards flexible work arrangements, notably work-from-home (WFH) practices, has prompted significant discourse on their potential to reshape urban landscapes. While existing urban growth models (UGM) offer insights into environmental and economic impacts, There is a need to study the urban phenomena from the bottom-up style, considering the essential influence of individuals' behavior and decision-making process at disaggregate and local levels (Brail, 2008, p. 89). Addressing this gap, this study aims to comprehensively understand how evolving work modalities influence the urban form and land use patterns by focusing on socioeconomic and environmental factors. This research employs an Agent-Based Model (ABM) and Artificial Neural Network (ANN), integrated with GIS technologies, to predict the future Land Use and Land Cover (LULC) changes within Roanoke, Virginia. The study uniquely explores the dynamic interplay between macro-level policies and micro-level individual behaviors—categorized by employment types, social activities, and residential choices—shedding light on their collective impact on urban morphology. Contrary to conventional expectations, findings reveal that the current low rate in WFH practices has not significantly redirected urban development trends towards sprawl but rather has emphasized urban densification, largely influenced by on-site work modalities. This observation is corroborated by WFH ratios not exceeding 10% in any analyzed census tract. Regarding model performance, the integration of micro-agents into the model substantially improved its accuracy from 86% to 89.78%, enabling a systematic analysis of residential preferences between WFH and on-site working (WrOS) agents. Furthermore, logistic regression analysis and decision score maps delineate the distinct spatial preferences of these agent groups, highlighting a pronounced suburban and rural preference among WFH agents, in contrast to the urban-centric inclination of WrOS agents. Utilizing ABM and ANN integrated with GIS technologies, this research advances the precision and complexity of urban growth predictions. The findings contribute valuable insights for urban planners and policymakers and underline the intricate relationships between work modalities and urban structure, challenging existing paradigms and setting a precedent for future urban planning methodologies. / Doctor of Philosophy / As more people start working from home, cities might change unexpectedly. This study in Roanoke, Virginia, explores how work-from-home (WFH) practices affect urban development. Traditional city growth models look at big-picture trends, but this study dives into the details of workers' individual behaviors and their residential choices. Using advanced computer models such as machine learning and geographic information systems (GIS), predictions are made on how different work arrangements influence where workers live and how cities expand. Surprisingly, fewer people work from home than expected. This hasn't caused cities to spread out more. Instead, Roanoke is expected to become denser in the next ten years because on-site workers tend to live in urban centers, while those who work from home prefer suburban and rural areas and, sometimes, urban. Different work arrangements lead to distinct residential preferences. By including the workers' individual behaviors in the models, the model's accuracy increased from 86% to 89.78%. Logistic regression analysis highlights the factors influencing land use changes, such as proximity to roads, slopes, home values, and wages. This research helps city planners and policymakers understand working arrangement trends and create better policies to manage urban development. It shows the complex relationship between work practices and city structures, providing valuable insights for future city planning.

Uma metrópole em transição: reestruturação produtiva e a emergência do turismo na RM de Fortaleza-CE / A metropolis in transition: productive restructuring and the emerging of tourism over the metropolitan areas of Fortaleza - State of Ceará- Brazil

Montenegro Júnior, Ignácio Ribeiro Pessoa 26 September 2012 (has links)
A pesquisa tem como objetivo lançar luz sobre o debate em torno das transformações socioespaciais recentes nas cidades brasileiras. Nestas, observam-se processos e nichos de mercado vinculados a produtos imobiliários que participam como causas da dissolução urbana nas metrópoles contemporâneas, caracterizadas pela fragmentação territorial e segregação social. Enfocando os produtos imobiliários vinculados ao turismo, buscamos compreender como se dá a articulação dessa forma de produção social do espaço baseada na emergência de um novo quadro de agentes sociais. Tais agentes são considerados como sujeitos que realizam práticas urbanas inovadoras comprometidas, contudo, com a lógica de reprodução do capital. Este enfoque se justifica por provocar uma discussão em torno dos conceitos de \"padrão de ocupação\" e \"estruturação espacial\", na perspectiva de compreender o novo papel dos agentes imobiliários articulados ao turismo. No primeiro capítulo, abordamos a discussão teórica sobre a produção da cidade contemporânea no contexto da reestruturação, trabalhando os fundamentos da produção e apropriação do espaço urbano contemporâneo. Como ponto de partida, lançamos mão do conceito de espaço social e sua produção como estratégia de acumulação do capital, ressaltando o papel do mercado e do Estado na organização espacial da produção. Na sequência, discutimos a questão da transição metropolitana e a dissolução urbana das cidades contemporâneas, utilizando o conceito de reestruturação, associado ao de globalização, ressaltando o novo padrão de cidade e a nova configuração espacial. No segundo capítulo fazemos a primeira aproximação com a questão central, analisando a urbanização litorânea no contexto da reestruturação metropolitana de Fortaleza. Desse modo, examinamos as especificidades das Zonas Costeiras, o processo de ocupação do litoral cearense e a consolidação de Fortaleza como capital, enfocando em detalhes, o seu processo de metropolização. Para isso, partimos de uma análise que cobre desde a industrialização tardia no Nordeste à reestruturação produtiva e sócio-territorial do Ceará contemporâneo, a fim de ressaltar a emergência do turismo em sua relação com a produção do novo espaço urbano litorâneo. No terceiro capítulo, tratamos a questão central da reestruturação metropolitana e a emergência do turismo, enfocando a participação dos agentes imobiliários no caso de Aquiraz. Essa escolha deve-se ao fato de que esse trecho do litoral revela de modo mais evidente a questão em foco, proporcionando elementos conclusivos capazes de consolidar nossas considerações finais. Assim, foi possível concluir que a ação desses agentes imobiliários responde à reorganização de um novo processo de produção do espaço para o turismo, frente à necessidade de incorporar novos territórios à lógica de reprodução do capital. / The objective of this research is to shed light on the debate about recent socio-spatial transformations in Brazilian cities. One can observe in these transformations market processes and niches linked to real-estate products that participate as the causes for the urban dissolution in contemporary large cities, characterized by territorial fragmentation and social segregation. While focusing on those real-estate products that are linked to tourism, we have aimed to understand the process by way of which the articulation of such new form of social production of space, based on an emerging scenario created by social agents, takes place. Such agents are seen as the subjects who bring forth innovative urban practices though intrinsically committed to the logic of quick increase of capital. Such focus can be justified for provoking a discussion about the concepts of occupation pattern and spatial structuring, as an attempt to understand the new role played by real-estate agents involved in tourism. In the first chapter we approach the theoretical discussion on the production of contemporary cities in a re-structuring context, analyzing the fundamentals of production and appropriation of the contemporary urban space. As our point of departure, we took over the concept of social space and its production as a strategy towards the accumulation of capital, emphasizing the role played by the market and the State in the spatial organization of production. Then we discussed both the metropolitan transitional issue and the urban dissolution of contemporary cities, by using the concept of a restructuring standpoint associated with the concept of globalization, emphasizing the new pattern of city as well as the new spatial configuration. In the second chapter we carry out the first approximation to the central issue, analyzing the coastal urbanization in the context of the metropolitan re-structuring of Fortaleza. Thus, we examined the detailed features of the Coastal Areas of Ceará, the \'occupational process\' of those areas and the consolidation of Fortaleza as a Capital City, by emphasizing, in detail, the process as it gradually became a metropolis. For that reason, we started from an analysis that comprehends from the belated industrialization of the Northeast of Brazil to the productive and socio-territorial re-structuring of modern Ceará in order to emphasize the emergency of tourism in its relation to the production of a new urban coastal space. In the third chapter we treated the central issue of both the metropolitan restructuring and the emerging need for tourism, focusing on the participation of real-estate agents as in the case of Aquiraz. Such a choice is due to the fact that that coastal line reveals more clearly the issue under analysis, creating conclusive elements capable of consolidating our final considerations. Thus it was possible to say in conclusion that \'the action of those real-estate agents respond to the re-organization of a new process of production of space for tourism, in the face of the need to incorporate new territories into the logic of capital growth\'.
