Sistemas de dunas do parque das Dunas e Barreiras do Inferno/Natal (RN: levantamento geológico /geofísico, elaboração do modelo deterministico e avaliação da vulnerabilidade/suscetibilidade

The current work was developed on the dune systems of the Parque das Dunas and Barreira do Inferno. These places are located in the cities of Natal and Parnamirim (RN, Brazil), respectively. This project has the purpose of developing the deterministic model on a specific blowout at Parque das Dunas, based in the geophysical interpretations of the lines gotten with the Ground Penetration Radar and the planialtimetric acquisitions of the topographical surface of the land. Also analyses of the vulnerability/susceptibility of these dune systems had been done in relation to the human pressures. To develop its deterministic model, it is necessary to acquire inner and outer geometries of the cited blowout. In order to depict inner geometries underneath the surface are used the GPR observing the altimetric control for topographical correction of the GPR lines. As for the outer geometries, the geodesic GPS gives us the planialtimetric points (x, y and z points) with milimetric precision, resulting in high-resolution surfaces. Using interpolation methods of the planialtimetric points was possible create Digital Elevations Models (DEM´s) of these surfaces. As a result, 1,161.4 meters of GPR lines were acquired on the blowout at the Parque das Dunas and 3,735.27 meters on the blowout at the Barreira do Inferno. These lines had been acquired with a 200 MHz antenna, except the 7 and 8 lines, for which we had been used a 100 MHz antenna. The gotten data had been processed and interpreted, being possible to identify boundary surfaces of first, second and third order. The first order boundary surface is related with the contact of the rocks of the Barreiras Group with the aeolian deposits. These deposits had been divided in two groups (Group 1 and Group 2) which are related with the geometry of stratum and the dip of its stratifications. Group 1 presented stratum of sigmoidal and irregular geometries and involved bodies where the reflectors had presented dips that had varied of 20 to the 28 degrees for the Parque das Dunas blowout and of 22 to the 29 degrees for the Barreira do Inferno blowout. Usually, it was limited in the base for the first order surface and in the top for the second order surface. Group 2 presented stratum of trough, wedge or lens geometries, limited in the base for the second order vi surface, where the corresponding deposits had more shown smoothed reflectors or with dips of low angle. The Deterministic and Digital Elevation Models had been developed from the integration and interpretation of the 2D data with the GOCAD® program. In Digital Elevations Models it was possible to see, for the localities, corridor or trough-shaped blowouts. In Deterministic Model it was possible to see first and second order boundary surfaces. For the vulnerability/susceptibility of the dune systems it was applied the methodology proposal by Boderè al (1991); however the same one did not show adequate because it evaluates actual coastal dunes. Actual coastal dunes are dunes that are presented in balance with the current environmental conditions. Therefore, a new methodology was proposal which characterizes the supplying and activity sedimentary, as well as the human pressures. For the methodology developed in this work, both the localities had presented a good management. The Parque das Dunas was characterized as a relic dune system and the Barreira do Inferno was characterized as a palimpsestic dune system. Also two Thematic Maps had been elaborated for the environmental characterization of the studied dune systems, with software ArcGis 8.3, and its respective data bases

Organização espacial e processo saúde-doença no bairro Guarapes, Natal/RN

La santé et la maladie sont des objets de préoccupation dans la société. Tout au long de l'histoire de l'humanité, ils ont été traités sous différents yeux. La géographie est une façon de comprendre les processus liés à des questions de santé et de maladie, de façon privilégiée dans le but d'être une science concernées par la zone géographique où cela implique non seulement une structure de la matière, mais les personnes et les flux découlant de la relation est établie Entre la société et la nature. Un lien est établi entre l'organisation spatiale de la santé-maladie est au c ur de ce travail, avec la coupe Guarapes espace du quartier, situé dans l'ouest de la Région administrative de Natal (plus bolsão pauvreté de la ville) pour la période correspondante de la 1990 par 2004 (jalon important pour le bien et la dynamique des populations de la zone d'étude) et de réduire le temps de la recherche. Au cours de l'analyse procède à l'étude des formes de production et d'organisation de l'espace vécu. Depuis comprendre le quotidien des personnes souffrant d'un réseau de relations, motivés par les besoins et la solidarité qui génèrent des formes et des contenus qui façonnent l'aire géographique. Sur la base de revue de la littérature, la recherche empirique à travers la réalisation des feuilles de route des entretiens avec le représentant des gens du quartier (résidents, des dirigeants communautaires, des coordonnateurs pédagogiques, des infirmières et des agents de santé de la PSF). Outre les visites effectuées à l'Agence de régulation des services d'assainissement de la municipalité de Noël - ARSBAN, le Secrétariat spécial pour l'Environnement et Urbanisme - SEMURB, secrétaire du Travail et de la protection sociale SEMTAS, Secrétariat municipal de la santé - SMS. Sur la base de l'espace vécu voir que les éléments du quotidien local exercer une forte influence sur la santé et La maladie de la population étudiée, avec un accent sur les problèmes découlant de chômage, sous-emploi, l'insécurité et un manque d'assiduité de certains responsables de l'USF - Guarapes. La production et l'organisation de la région convergent à l'apparition de maisons, les rues et les petits commerces non équipés de l'infrastructure de base dédiée à la prise en charge des personnes favorables à l'occupation désordonnée et non planifiée pour plusieurs zones du district, ainsi que l'apparition De vecteurs transmetteurs de maladies

Setor informal da economia e a dinâmica dos territórios nas praias da cidade do Natal/RN

La recherche sur secteur non-formel de l économie et la dynamique des territoires dans les plages de la ville de Natal/RN, a le but de la compréhension des espaces de ces territoires ainsi que leurs caractéristiques; le rapport des acteurs sociaux et l existence de politiques dirigées direct ou indirectement vers ce secteur de l économie et ses territoires. Pour celà, on donne emphase au scénario économique moulé par le système de production et reproduction dans la mondialisation, ce qui, parmis d autres actions aq l inetrférence sur le marché du travail, lequel subit constamment des transformations importantes cherchant à suivre les changements en niveau global, en devenant, pour ainsi dire, un marché chaque fois plus exigeant et, conséquemment, sélectif. Moyennant la réalité économique et politique vécue, il augmente le nombre de chômeurs dans le pays suscitant, à tort et à travers, la croissance du secteur non-formel de l économie avec ses inombrables travailleurs qui occupent les plus différents segments parmi lesquels les travaux autonomes, ici représentés par les camelots, les propriétaires de baraques, les propriétaires de kiosques ; etc. Pour atteindre ce but, on a cherché les reférenciels théorico-scientifiques ayant pour base la connaissance empirique à travers les inombrables cas d études matérialisés au moyen de donnés primaires et sécondaires. Finalement, on est sûr de ce que les travailleurs du secteur non-formel complèmentent la chaîne repoductive, ils créent et recréent des territoires avec des contenus variés qui sont indispensables pour la croissance et le développement social

Monitoramento da qualidade das ásguas de chuvas conforme a atuação dos sistemas sinóticos na cidade de Natal/RN

Acid rain is a major assault on the environment, a consequence of burning fossil fuels and industrial pollutants the basis of sulfur dioxide released into the atmosphere. The objective of this research was to monitor and analyze changes in water quality of rain in the city of Natal, seeking to investigate the influence of quality on a local, regional and global, in addition to possible effects of this quality in the local landscape. Data collection was performed from December 2005 to December 2007. We used techniques of nefanálise in identifying systems sinóticos, field research in the search for possible effects of acid rain on the landscape, and collect and analyze data of precipitation and its degree of acidity. Used descriptive statistics (standard deviation and coefficient of variation) used to monitor the behavior of chemical precipitation, and monitoring of errors in measurements of pH, level of confidence, Normalized distribution of Gauss, confidence intervals, analysis of variance ANOVA were also used. Main results presented as a variation of pH between 5,021 and 6,836, with an average standard deviation of 5,958 and 0,402, showing that the average may represent the sample. Thus, we can infer that, according to the CONAMA Resolution 357 (the index for fresh water acidity should be between 6.0 and 9.0), the precipitation of Natal / RN is slightly acidic. It appears that the intertropical convergence zone figures showed the most acidic among the systems analyzed sinóticos, taking its average value of pH of 5,617, which means an acid value now, with a standard deviation of 0,235 and the coefficient of variation of 4,183% which shows that the average may represent the sample. Already in field research and found several places that suffer strongly the action of acid rain. However, the results are original and need further investigation, including the use of new methodologies

As faces da exclusão social na comunidade África - Natal, RN

This dissertation deals with the study of the faces of social exclusion at present, through a spatial section constituted of a subnormal area (the Community Africa), which groups these aspects in a limited, but revealing, context regarding such problems. Through the following chapters, inequality, exclusion, segregation, the socioeconomics of the Community Africa, and the environmental impacts identified in this community are discussed. At the end of this piece of work, alternatives of possible solutions to the community area pointed, with also the discussion of propositions related to the questions concerning the mitigation of the most relevant problems

Arborização urbana e percepção ambiental: uma análise descritiva em dois bairros de Natal / RN.

The current paper aims to check the environmental population perception of the two east side districts of Natal / RN (Rocas and Petrópolis) on its afforestation. The issues related to the environmental perception and afforestation of cities are gaining prominence in the many different areas of knowledge. However, the approaches and methodologies that are following an analytical perspective that by the rule aimed an policy of spatial planning not always responds to the aspirations and needs of the urban population. The research has been consisted of a preliminary survey, collecting data through the representative population of the neighborhoods in Petrópolis and Rocas, which were applied 210 forms (with the households), 130 in the neighborhood of Rocas and 80 in Petrópolis, which corresponds to 5% of the total households of the two districts, using as indicators, among many others, the income, the level of education and the environmental characteristics of the neighborhood. Through analysis sample was possible to verify that Petrópolis neighborhood that, 68% of interviewee believes their lives in the neighborhood where good and only 2% consider bad, in Rocas neighborhood, 57% considered life in his neighborhood good and only 5% consider bad. When asked about the main characteristics that remind the neighborhood Petrópolis, 90% of residents mentioned that one of its main advantages are the means of transport available, followed by 82% who quoted the ventilation as one of the main benefits of the neighborhood. In Rocas neighborhood, items mentioned by residents, were the ventilation with 47% of all interviewee and 32% said that peace is one of the most positive point of the neighborhood. From the description of some of the environmental needs of the neighborhoods Petrópolis and Rocas, it is possible to infer that environmental issues in general, and afforestation are always present in the speech of the residents, even indirect way, it shows that regardless of the education degree or the income, environmental quality is present as one of the basic needs of urban areas with implications both in the personal and social life as of its inhabitants.

Para onde sopram os ventos :politicas públicas de turismo no grande Pirambu/Fortaleza/CE

PARA ONDE SOPRAM OS VENTOS , metaphor used to indicate turism public politicsway to the west zone of Fortaleza, against the direction where until now this public politics was targeted, to the east zone. This context, análise the public politics implemented in the Grande Pirambu, so like the processes of nonterritorialization and reterritorialization unchain by the program os settlement and indemnification of the Projeto Costa Oeste. Aim to learn the transformations that unroll in the studied área, based in proceding methodologic that privileged the interviews with many social actors resettled, indemnificators, intirenants, livers and fishmen. The public politics analyzes run to the Grande Pirambu infer that the same answer at trying of urbam requalification of the área, object of the new exigence pretender by the touristics activities developed in Fortaleza, wish to incorporate this área at the turistics dynamic of the city. However, the implementation of the Projeto Costa Oeste do not occuring in calm way, by opposite sence the beginning, the same has been propitiated polemics and discussions, stired up about public politics between the municipa and state power, to bring about injury in the public coffers, to the developing turismo f the city and, mainly to the living around Grande Pirambu, unquiet and sad with the buildings of the referring project that there is running for four years

A reafirmação do bairro:um estudo geo-histórico do bairro do Alecrim na cidade de Natal-RN

By the end of the 21st Century, economy globalization trends to show a velocity process through which market being expanded characterized by an intense going on of the internationalization of finance, after that marginalizing the periphery of the social spaces. It is clear to see that this process occurred in those less developed countries happens in an accentuated way just because income distribution that is so regressive and also because the insufficient enclosing of the social programs, we find this situation in a big part of Brazilian cities. The marginalizing social economical process observed in Natal, a city located in the east coast part of Northeast region in Brazil and that owns a population upper to 778 thousand in habitants is nearly linked to the extension of goods and services commerce. The installation of new urban activities in the city pointed out tourist activity as the greater impulsive thing in the phenomenon promotion, most of them aiming to promote Natal to the national and international scenery. It privilege strongly in the South zone with economical implementations such as shopping s centers, supermarkets, and home buildings condominiums leading to a loss of functionality of some traditional district located in central areas of the city. Notwithstanding, some spaces, for instance Alecrim district officially created in 1911, has notably resisted to the expansion of the urban process pointed out in Natal in the last years. So that this put Alecrim District as a district with originally characteristics reaffirmed along the historical process form old times. The predominance of some residential characteristics such as the incidence of some villages and a concentration of a big and confuse popular commerce distributed along streets puts Alecrim District as a resistant space in Natal. The same way analyze Alecrim District under the prism of Historic Geography because we understand this way it accomplishes a fundamental role in the theoretical methodological development of our work, just when we analyze the time as a variant in our object of study. It is still inside this theoretical field that we carry out a brief reviewing about quarter/district definition, under the optic from several registered and scientific resources taken into account along this work, because we understand that it was necessary to think this important spatial unit especially to know exactly what we are referring to as a district and so we can reaffirm Alecrim as an important and traditional district to Natal and it has been resisting to spatial transformation verified in the last years in Natal city. To give support to our reflection we used methodological tools related to inhabitants lifestyles knowledge and also the study of Alecrim District as a space that promote a certain centrality in Natal as some indicators to keep original characteristics in the district in Natal

O uso do território pelos serviços privados de saúde em Natal/RN

Nowadays we can observe in Natal city, the development of the structure and the health s private service. However, the spatial distribution of these services will be marked by an uneven distribution on the places, what will be in according with the conditions offered by the same in each historical period. Accordingly, the objective of this job is analyze the use of the territory by the health s private service and the dynamics that promotes in Natal city in the technical scientific information period. Thus, seeking to search this goal, realized literature, documentary, empirical, considering the process of development and the spatial distribution of the health s private service in the city. From a topology we can observe that prevails in the city a service s concentration at all levels of complexity in only a few neighborhoods, being Tirol and Petrópolis, which are neighborhoods that have high densities of engineer system, bigger fluidity, and the best level salaries of the city, which present a greater number of these establishments. However, equal this concentration has occurred a dispersion of these services to other neighborhoods, as for example Lagoa Nova which is presenting the same attractiveness in the view of attributes territorial, begins to protect services presenting the same profile like the firsts. However, the city has a significant demand to this kind of service found in these neighborhoods, some events provided the emergency of another type of market of health s private service, that are those created to attend guests with a lower purchasing power, which will have their establishments in the same way selectively distributed in some areas of the city, which will not be the same pursued by the other, showing how selective is the installation of an enterprise guide by the logic of capitalism reproduction. So, the imperative of spatial selectivity presented by the health s private sector exposes an use of the differential territory for these services

A dinâmica territorial do comércio varejista moderno da Zona Norte de Natal/RN

This work studies the territorial dynamics of the trade modern retailer in the North Zone of Natal/RN, undertaken by the expansion of that following of the tertiary section in the researched space. For so much, we accomplished bibliographical and documental research during whole the process of construction of the work and the field research based close to in interviews the responsible for the establishments of the modern retail and application of questionnaires with the residents and consumers of the area in subject. Leaving of the understanding that the territory is used by the society producing the movement of capitalist reproduction in the places, we inferred that the expansion of the modern retail in the North Zone has been promoting a new dynamics in your territory, fact that has been valuing the space and attracted investors to the place. Therefore, we organized the study in this dissertation in three chapters: the first, "North Zone: use and occupation of the soil ", brings us the process of historical and social formation of the North Zone inserted in the context of the urban expansion of Natal; the second chapter, " Expansion of the tertiary section: the growth of the modern retail trade in the North Zone", makes direct reference to the tertiary section and the expansion of the I trade modern retailer; and finally, the third surrender, " The territorial dynamics and the modern retail trade in the North Zone of Natal", in which we expose all the results of the field research, looking for to understand the territorial dynamics that the expansion of the modern retail trade has been producing in the study area

O esgotamento sanitário e o uso do território em Natal/RN (1969 - 2009)

Natal é uma cidade bastante antiga, data desde o ano de 1599. Durante seus três primeiros séculos de existência ela praticamente não cresceu, porém teve um significativo aumento populacional e crescimento urbano na década de 1940, a partir da Segunda Guerra Mundial. Nos últimos anos, Natal tem passado por um intenso processo de urbanização, que exigiu da cidade um acompanhamento na sua infraestrutura, principalmente por ser uma cidade turística; o que aumenta bastante a sua demanda. O esgotamento sanitário entra como um dos problemas que Natal tem que resolver. A cidade possui apenas cerca de 32% do seu território servido por um sistema de coleta de esgotos. O serviço de esgotamento sanitário é de extrema importância para a manutenção da saúde e da qualidade de vida da população, assim como os demais serviços que compõem o saneamento básico. Tal serviço tem sido um grande desafio para a população e para os administradores públicos. Este trabalho tem como principal objetivo analisar os impactos socioespaciais causados pelas diferentes formas de esgotamento sanitário existentes em Natal. Durante a elaboração deste trabalho, foram realizadas pesquisas bibliográfica e de campo através de estudos documentais, visitas aos órgãos públicos, entrevistas, aplicação de formulários junto à população e observação direta. O embasamento teórico parte dos estudos de Milton Santos sobre território usado, adotando também, ao longo do desenvolvimento do trabalho, as contribuições de outros autores. O território usado foi escolhido como categoria de análise deste trabalho, por entendermos que as questões do esgotamento sanitário passam pelo uso do território, e este se dá pela sociedade como um todo

Mercado imobiliário informal e dinâmica urbana: o caso do bairro de Mãe Luiza Natal/RN

This paper aims at analyzing the dynamics of informal housing in Mãe Luiza, in the context of real estate valuation of the city of Natal/RN, which, like any other urban center, has problems related to access to urban land, which increasingly more is appreciated due to their scarcity and, consequently, has led to the segregation of urban spaces. Recently, the informal housing market has received special attention by scholars who wish to discuss the production of space and ways of access to urban land and housing, especially for those disadvantaged by the housing policies of the government where these exist. When talking about the housing market, we are automatically referring to concepts or categories intrinsic to the existing mode of production in our society - the capitalism. Thus, the categories: income, value (use and exchange), commodity, capital, profits and capital gains, along with other important concepts as well as land use (urban) and real estate agents are of great relevance to discussion we intend to do within the context of production space

Praia de Ponta Negra: uma abordagem da paisagem costeira de 1970 a 2010, Natal/RN

With process urbanization process the Brazilian cities have been goin through, Natal/RN does not differ from the other ones, it has had a fast, inordinate and planned urbanization, but not applied, it has caused a high increase of social environmental problems. One of the worrying problems observed is the change in the coastal landscape, which has caused serious damage to the city‟s population, more specifically, of Ponta Negra beach neighborhood. For the geographical studies, the issue, concerning the occupation of the beaches that has been getting higher and higher in the last decades is extremely important because these, in addition to being used as homes in the new urban configuration, have incorporated new ways of environmental interference, without a simultaneous advance of knowledge which would be necessary for a more suitable and rational use of litoral spaces. Thus, the current assignment aimed to focus the coastal landscape of Ponta Negra Beach, in the city of Natal/RN, checking and analyzing the effects caused by anthropic and natural action, and the way it reflects in the quality of life of the resident, working population and of the frequenters as well as the landscape transformations in the area which is object of study, from 1970 through 2010. The methodology used followed to stages, the first concerned the theoretical work bibliographic surveying and composition; and second one the empirical work marking of the environmental characterization and application of the questionnaires. So, we can measure that Ponta Negra, is very susceptible to environmental changes, the ones caused by the natural dynamics of the beach, as well as the human actions (society) in this really fragile and mutable space, so it needs, a more profound systematic study about the coastal landscape. In order to reach a minimization of the change of the landscapes in the coastal zones there must be an integrated management of the environments, based on the planning of actions and territorial reordination of the occupations of these so important spaces, environmentally, as well as socioeconomically. Whereas, only this way, we will have a sustentable development and a suitable use of that space
