Uma cidade em transformação: a influência da atividade do crediário nas mudanças da paisagem urbana de Tenente Ananias-RN

Studies on the urban landscape and on the changes of the urban space are relevant, since they reveal the economic dynamics and the way of life in the cities. Research on small towns, in particular, can display particular aspects and by so doing broaden the comprehension of this theme. The purpose of this research is to analyze the changes in the urban landscape and in the way of life of the inhabitants of the town of Tenente Ananias-RN that have been taking place since the 1990s up to the present (2013) and which result mainly from the commercial activity of crediário. The study is, therefore, a reflection on the impact of crediário economy on the urban landscape and on the way of life of a small town located in the hinterland of the State of Rio Grande do Norte. For this reason, it was necessary to study the landscape and the way of life found in Tenente Ananias in two moments: a) before the rise of the crediário, a period of time ranging from the town‟s initial emergence until the beginning of the 1990s; b) during the progress of crediário activity, from the beginning of the 1990s, when it starts, up to the present (2013). For this research, primary data (interviews, local survey visits) and secondary data (books, articles, reports, census data) were used. As a result of this study, it was possible to conclude that crediário plays a fundamental role for the explanation of the changes taking place in Tenente Ananias-RN, especially in the urban landscape and in the way of life of people. We have attempted, through this research, to contribute to the studies of a historical, social and economic process related to the urban landscape and space of a small town in the State of Rio Grande do Norte

Parâmetros urbanísticos na regulação do uso e ocupação do solo: estudo da densidade e do coeficiente de aproveitamento nos planos diretores de Natal de 1994 e 2007

A Constituição Federal de 1988 e o Estatuto da Cidade estabelecem o Plano Diretor como instrumento básico da política de ordenamento territorial, tendo como princípio fundamental o cumprimento da função social da propriedade e do direito à cidade. Na perspectiva de adequação às diretrizes e objetivos da política urbana estabelecidos em 1988, o município de Natal elaborou os Planos Diretores de 1994 e 2007, definindo instrumentos e parâmetros de regulação do uso e ocupação do solo possíveis de assegurar o cumprimento da função social da propriedade urbana e de gerar subsídios ao planejamento e à gestão da cidade. Apesar de Natal ter sido um dos municípios brasileiros pioneiros na adoção desses princ pios, antecipando e incorporando os instrumentos que em 2001 viriam a ser definidos no Estatuto da Cidade, identifica-se que alguns desses instrumentos e parâmetros direcionados à regulação do uso e ocupação do solo não tiveram sua aplicação plena, a exemplo do mecanismo de acompanhamento e controle dado pelo Estoque de Área Edificável e da Densidade, que foi substituída pelo Coeficiente de Aproveitamento no Plano Diretor de 2007. Questionando esse procedimento, busca-se na presente pesquisa investigar de que maneira essa substituição do parâmetro densidade pelo coeficiente de aproveitamento influenciou na capacidade da gestão pública de regular os processos de uso e ocupação do solo, de forma a adequar a sua intensificação ao suporte da infraestrutura instalada. Foram tomadas como referência teórico-conceitual as contribuições sobre a prática de planejamento urbano no Brasil, nos marcos do ideário da reforma urbana, com destaque para as reflexõe s de Flávio Villaça, Orlando Alves Santos Junior e Daniel Todtmann Montandon, Luiz César de Q. Ribeiro, Raquel Rolnik, Ermínia Maricato, Laura Machado de Bueno e Renato Cymbalista, José Roberto Bassul e Carlos F. Lago Burnett, e, com relação aos parâmetros de controle urbanístico, o estudo identifica as diferentes abordagens sobre a densidade urbana e o coeficiente de aproveitamento com base nas reflexões de Claudio Acioly Jr., Forbes Davidson, Juan Luis Mascaró, Ricardo Ojima, Marcelo de Souza, José Rámon Navarro Vera e Armando Ortuño Padilla, Nestor Goulart Reis, Marta Dora Grostein e Susana Ricardo Alves. Como conclusão, discute-se a hipótese formulada, inicialmente, de que a mudança de parâmetros verificada colocou limites para o município realizar uma gestão adequada do solo urbano e, portanto, de fazer cumprir a função social da propriedade, considerando a necessidade de adequação entre a intensificação do uso e ocupação do solo e a infraestrutura instalada

Espaço público e sociabilidade urbana: apropriações e significados dos espaços públicos na cidade contemporânea

Study public space is studying the city and its dynamics through a representation point. The changes that are observed in these spaces and in the relations established there, or with it, are related to changes that occurred in the city as a whole, in the urban way of living. Study public space allied to urban sociability permits an even better focus on this relation between people in these spaces and with the spaces and in the consequences and fragile aspects this relation can impose to people and cities. This work is aimed towards this relation between public space and urban sociability. Through a conceptual/theoretical discussion aims, specifically, comprehend how to establish and what is the relation between urban space and urban sociability (appropriation/perception of place, tendencies of seclusion), from an isolated analysis of each one of these themes in the contemporaneous city. The Brazilian public space has peculiar characteristics, arising from its historical process of construction, also influenced by the public sphere fragile construction that permeates it, as well as more recent variables such as the sensation of insecurity and commodification of these places. The urban sociability influences and is influenced along all this process of significance and reframing of the public space. The conceptual discussion about each isolate variable provides the necessary coverage for discussion and analysis of the relation between them and the consequence of this relation in the city, such as the notation of relevant experiences of this process of revaluation of the public space. The hereby search is not through a path to reestablish the relation as it already existed, but also for an understanding of the dynamic as is established today and for existing possibilities for maintenance and appreciation of the relation between people and the city by believing in its importance to urban life

Percepção ambiental do patrimônio cultural: estudo de caso na Cidade Alta e Ribeira em Natal-RN

Contemporary studies have shown that the evolution of the heritage concepts is accompanied by an affirmation of the importance of social participation in recognizing heritage values and in managing cultural assets. We used the Brazilian context to emphasize the challenges for democratizing this process. This problematic is discussed based on the cases of Cidade Altaand Ribeira, neighborhoods that date from the formation of Natal-RNand have cultural assets recognized by levels of government. The study builds elements to answer the research question: what meanings and representations does the culturalheritage in the case study have for its users? The research method analyzes the representations and the meanings of the neighborhoods, firstly is based on historiographical studies, memories records of the city and on the process of heritage management. Secondly, it isbased on the field research, it is structured in environmental perception studies (areas of Environmental Psychology, Architecture and Urbanism) and has been applied with users with different bonds with the studied environment (residents, workers and visitors). The data were obtained with the multi-method which included direct observation, questionnaire survey and mentalmaps (that replicate Kevin Lynch). The analysis of result verified the research hypothesis, emphasizing aspects of the relationship between users and cultural heritage relevant to strengthening collective memory, local identity, contributing to heritage management. Among the results, the socio-environmental image obtained which emphasized a "cultural axis" linkingboth studied neighborhoods and confirms the influences of elements rein the memories records of the city and in the area s management. Identified aspects to strengthen the relationship between the users and cultural assets, such as the presence of placeswith affective ties to certain groups, as well as the need to fight off negative images (of degradation and insecurity) associated to the site and also expand the participation of the population, including residents, in policies and cultural activities. After all, recognition of value and the involvement of societycultural assets have the potential of contribute to integrate city development with heritage conservation

Geografia da dominação: um estudo sobre a organização espacial da terra do sal (Macau-RN)

This work aims to understand the spatial organization in the Town of Macau, State of Rio Grande do Norte, Brazil. This approach focus on bringing back the history of the town, the main personages responsible for the construction of this place, denominated "social agents", as well as its social processes and the spatial forms derived from them. As the personages and their practices were identified, it was found out the existence of a driving force for structuring, interlocking, and maintaining the actions carried out by the social agents during the time. Such actions were materialized in the urban space: "the social segregation". The social segregation takes place as a specific geography of domination. The outcome of those owning the best areas" and ways of accessibility in the urban space, varies from the enrichment by property valorization, because of the concentration of public investments of infrastructure, to the comfort of easily reaching all the daily needs related to the displacements in the urban space. In the latter case, such facility has contributed to improve life quality. While one takes advantage of the location in the urban space, others are negatively affected by the same process. This research identified the salina worker as the weakest element of this social structure, occupying the urban periphery of the town of Macau. Such area is characterized by the lack of services and urban equipment in opposition to the center of the town, the locus of elite. This way, it is established the most known segregation pattern: center x periphery, in which the space acts as a mechanism of segregation

Um espaço pioneiro de modernidade educacional: Grupo Escolar Augusto Severo -Natal/RN -1908-13

Cette recherche a pour but d analyser l Ecole Augusto Severo, située dans la ville de Natal dont la construction date de 1907,étant le premier établissement d enseignement primaire à l état du Rio Grande do Norte, pendant le processus de restructuration de l enseignement républicain. On cherche à comprendre la représentation de ce milieu scolaire, comme équipement urbain, dans le processus de modernisation de la ville et comme modèle éducationnel pour l état entre 1908 et 1913. En se servant des études historiographes sur le processus de modernisation de quelques villes brésiliennes et des innovations de l enseignement public primaire au pays, à la fin du dix-neuvième siècle et pendant la première décennie du vingtième siècle, comme source pour mieux saisir le contexte général et spécifique. On reconstitue les aspects économiques, sociaux et politiques déterminants des interventions publiques réalisées dans cette ville par les gouvernements républicains ayant comme obectif la construction d une ville embellie,hygiénique et civilisée. Située au quartier Ribeira, principal scénario de la modernité de Natal, l Ecole Augusto Severo est mise em relief comme symbole de civilité du paysage urbain de l époque pour le citoyen du Rio Grande do Norte. Elle disposait de services d énergie et d un tram électrique. Il y avait devant, un grand lac arborisé et une station ferroviaire. A côté, il y avait le théâtre Carlos Gomes (actuellement Alberto Maranhão). Par suíte de son imposante architecture, raffiné style éclectique,on reflète l idéal républicain des elites locales, avec une conception d espace symbolique et éducative de surveillance et contrôle, caractéristiques de l école graduée républicaine

Indicações para o projeto arquitetônico de edifícios multifamiliares: uma análise pósocupação em Natal/RN

Confirming the Brazilian tendency in the field, the multifamily vertical condominium habitats in Natal are defined as buildings with three or more floors which have been an increasingly used solution. In the mentioned project, the connection between the projectarchitects and the user/ buyers are spread out, by which the first people conceive the realestate property as a creation for the market and not the individual client in specific. Such situation along with technical and financial limitations of the project lead to the adoption of standard solutions to be utilized by clients with different profiles. Besides that, there are various legal and urban parameters by the City Director Plan showing elements of great influence in the final solution adopted by the mentioned edifices. Moving to this subject in general, this project is focused on the case study of the Ed. Ville de Montpellier, having as a base of Post Occupancy Evaluation (POE), considered an efficient tool to analyze and keep up with the progress of the construction of the building, including technical approvals, the application of surveys with the local residents and the creation of informal interviews. The data shows that with time some items that initially motivated the acquisition of the realestate property (with a social common area) move to being less valued, and that the residents quickly alter the pre constructed space, thus seeking to alter the property in a more personal and conforming manner. The possibility of a new emphasis for projects on the mentioned space should also be in discussion, the created project calls for the attention of projected conceptual aspects and interdependence within project and construction which permits the indication of some recommendations for the projection of multifamily residential buildings within the studied realm

Dos caminhos de água aos caminhos de ferro: a construção da hegemonia de Natal através das vias de transporte (1820-1920)

At a time of changes on the territory during the 19th century, the political and socioeconomic elites of the province and later State of Rio Grande do Norte evolved a discourse in order to justify the permanence of Natal as a city holding a status of capital. In this work we analyze the means employed by the ruling classes to impose their wish to raise Natal to an outstanding position among the existing cities by intervening on the territory during a period of one hundred years (1820-1920). During that time, which was characterized by changing commercial flows and technological development, the elites interventions were essentially directed to the implementation of modes of transportation, especially the railway. We try to understand the reinforcement of Natal as a capital city not only in political and administrative terms, but mainly in a commercial and symbolic manner, through the discourse and interventions undertaken by the local administrative elites, who stimulated the creation of a set of relations on the territory that also imprinted visible marks in the capital s urban fabric. These interventions were based upon the establishment of an infrastructure for exporting the State s production, firstly through and despite the Potengi River, and later on by the construction of railways. Although the project of Natal s hegemony had been outlined before the establishment of the railway network, in both cases the ultimate objective was to reinforce and develop the capital city as a commercial urban center to the detriment of other cities

Paisagem, um patrimônio esquecido: subsídios para a construção de uma metodologia de valoração e proteção do cenário natural litorâneo

The so-called "residential tourism" came to intensify the previous occupation of the coastal zones, characterized by traditional beach houses, and brought significant consequences for their spatial configuration, and especially for its scenic value of the landscape. Although there is the intention to regulate the activities of enterprising groups by some legal instruments to control the use and occupation of land, and to contain some negative effects, the actions of government are still inefficient in trying to follow the implications on the landscape from the accelerated growth of the real estate and touristic sectors. Supported in the speech of economic development and income generation, public managers prioritize areas to attract tourists to the detriment of preserving important physical attributes of the natural environment that contribute significantly to the quality of life. The result can be noticed in the use of natural elements as one of the major components in the land valorization, and in the immediate attraction of investors and enterprising. Therefore, the objective of this work is to contribute to the debate on the landscape preservation a little detailed thematic in view of their relevance in the current context - by indicating subsidies to the creation of a methodology for the evaluation and protection of coastal zones that may assist the government in creating new instruments, and better prepare it in control of the occupation of these areas. For such, was followed two ways to analysis: the indirect method and the direct method. The first is grounded in the evaluation of landscape attributes, which is based on the work of Raquel Tardin (2008) and Eduardo Cuesta, Encarnación Algarra and Isabel Pastor (2001). The second, based on the research of Leticia and Carlos Hardt (2010) and on the concepts of phenomenology - expressed by Antonio Christofoletti (1985) and Yi-Fu Tuan (1983) - considers the population perspective on the quality of the natural scenery. Developed through cartographic materials, photographic collections and quantitative tables, this dissertation utilized as a case study the beaches of Barra de Tabatinga and Camurupim, located in the city of Nísia Floresta/RN. Despite already being sighted spaces of advanced stage of landscape degradation in these locations, areas of remarkable scenic value can still be found, what reinforce the urgency in adopting preservationists actions. The absence of laws focused on the management and protection of the landscape singularities associated with the inefficiency of the government to invigilate the land occupation in coastal zones, encourage the excessive action of the real estate-tourism, and consequently make the government the main responsible for the environmental and landscape impacts in these areas - by its omission or by their connivance. Therefore, the legislation permeates this entire process and constitutes itself as the most effective way to guarantee the right to the landscape to present and future generations. Are also pointed some important considerations to build a methodology, especially concerning possibilities of improvements and adaptations of its applicability in each case

Análise bioclimática e investigação do conforto térmico em ambientes externos: uma experiência no bairro de Petrópolis em Natal/RN

This study was intended to investigate how the urban form has been influencing the changes in the climate of the city and make a correlation between the climate and the thermal sensation of the users of open spaces. The research was developed in the district of Petrópolis in Natal/ RN whose occupation has been almost consolidated. Among other reasons, this district was selected because it was planned considering the environmental aspects of comfort. The methodologies used are based on KATZSCHNER (1997) and OLIVEIRA (1988) studies, which suggest the drawing and analysis of maps of the area under study, including topography, height of the buildings, land use, green areas, and types of soil pavement, as well as measurement of the environmental variables: air temperature, relative humidity, direction and wind speed for a comparative study. As part of this, study local users of the district were interviewed about their thermal sensations in open spaces. For the statistical analysis, data was collected at 10 distinct points characterized by BUSTOS ROMERO (2002), being 8 within the district and 2 at different places (outside the district), at climatologic stations, in 3 periods (August/2000, January/2002 and June/2002), for 4 consecutive days for each measurement (from Sunday to Wednesday) at the time of lower and higher temperatures in the city, 6:00 am and 1:00 pm, respectively. At the same time interviews were carried out with users of the open spaces in the area, totaling 171 valid formularies. The urban form showed a rather leveled topography, great diversity of land use and height of the buildings, with the existence of an area mostly occupied with high buildings, very little green area and soil practically impermeable. The statistical analysis showed high temperature and humidity levels. The wind direction is predominantly Southeast with extremely variable speeds. When the data from this district is compared with the data from other areas in the city and its outskirt, it was observed that this district is hotter and less ventilated than the others; besides, most users said that they felt uncomfortable in the local environmental conditions. The results of the analysis generated a zoning for the district with recommendations for soil occupation. The profile of the user was defined regarding the thermal comfort, as well as some discussion about the comfort parameters, including the proposal of limiting areas of temperature and humidity for the thermal comfort in the open spaces

Ventilação e prescrições urbanísticas: uma aplicação simulada no bairro de Petrópolis em Natal/RN

The present work studies the natural ventilation and its relationship with the urban standards, which establishes the form of occupation and use of the land in our cities. The method simulates the application of the urban standards of the City Master Plan over the last three years. The simulation takes place in the District of Petrópolis, in the city of Natal , Brazil and analyses the effects of the standards of natural ventilation. The formulated hypothesis states that the reductions in the urban spaces between buildings rises up the vertical profile of ventilation, reducing, therefore, the velocity of the wind at the lower levels of the buildings. To develop the study, occupation models were built, using computerized, three-dimensional models. These occupation models were analyzed using the CFD (Computational Fluid Dynamics) code. The conclusion is that the more we reduce the urban space between buildings, the more we reduce the wind speed in constructed areas, increasing, therefore, the possibility to generate heat islands

Estética do apocalipse: (re) considerações acerca da (des) arborização urbana de Natal e seu contributo à saúde pública

This study intends to establish a relation between environmental degradation, particularly the devastation of the green canopy, and public health. Utilizing a mapping of the trees included in the researched area, each individual tree was analyzed according to its age, taxonomic listing, architecture, shape and size (determined by aesthetic/convenience reasons or deformed by pruning). Initially investigated were the covert reasons lying underneath the constant aggression against trees (which many times seem to contain elements of hatred and contempt) within the urban environment. In addition to that, the aspects concerning environmental modifications and the consequent impact on public health were also assessed. Two main problems promptly emerged as a result of the removal of trees: a) without a canopy to protect the areas, they became subject to winds directly blown from SW Africa and impregnated with aerosol partic les, which are common causes for respiratory disorders and, b) direct UV solar radiation, which causes some types of skin cancers and eye disorders. To reach such results, we studied the origins and formation of UV radiation induced cancers and searched for the UV radiation spectra of action, e.g., usual intensity and quantity reaching clear and shadowed spaces in a certain area and its consequences. In a second instance, we also searched for pertinent data resources in order to confirm the increase of skin cancer cases due to exposure to UV radiation and the relation between the destruction of the green canopy and the above mentioned problems. We believe that a few significant results have been achieved by this study, namely: the relation between a culture based on medieval beliefs and its consequences on the environment; how this culture exploits and deforms nature in pursuit of financial and psychological interests to a point of transforming the landscape into a copy of something devoid of any relation to latitude and altitude; and above all, the indifference concerning the alarming results carried by these modifications

Clima urbano e vegetação: estudo analítico e prospectivo do Parque das Dunas em Natal

The present study deals with the relationship between urban vegetation and climate. The process whereby the Parque das Dunas a 1,172 ha green area in the city of Natal, State of Rio Grande do Norte exerts influence on the climate of the city is analyzed. The hypothesis on which the present work rests is that the green area referred to acts upon the climate of the city. The study is based on the analysis of climatic factors and elements of this green area and of the city of Natal. In order to give rise to final recommendations, a methodology grounded on a quantitative and qualitative standpoint has been used. The data were collected both within and without the limits of the Parque das Dunas area. Secondary and primary data resulting from the measurements taken by the researcher and her work group have been used. The aim was to contribute to the understanding of the influence of vegetation on the climate of a city having a warm and humid climate. A historical and environmental characterization of the Parque das Dunas was then sought. The local climatic factors and the elements of the climate have been studied within the scope of the city of Natal. A comparative study between the climatic elements within and without the limits of the Parque das Dunas area from the survey of technical data and the systematization of the information collected has been made, aiming at proposing a set of bioclimatic recommendations for the urban design in Natal. The results of such work allowed for the validation of the important role that the Parque das Dunas plays in the climate of Natal. This has led to the acknowledgement of the relevance of the green areas on the climate of cities. They bring about important benefits to the process of rendering agreeable the climate in the urban environment by providing pleasant microclimates that give a valuable contribution to the environmental comfort of urban nuclei having the same size of Natal
