A produção do espaço rural no município de Ceará-Mirim

This research intended to study the process of production of the rural space in the municipal district of Little Ceará-Mirim, looking for to identify the transformations in him happened, above all in the last thirty years. Since the beginning of your historical formation, the area in study had as element modelador and transformer of the physiognomy of your territory the culture canavieira that printed in your economy and in your society marks of a powerful nobility. The sugar-cane is covered of a cyclical character facing acme phases and decadence, as the one that it happens at the present time. Simultaneously, the sphere rural cearimirinense is going by changes by the implantation of modern companies gone back to the papaya production destined to the internal market and more precisely to the external market. Of this context they also consist the supplying farms of this same product. In the group of the establishments in the rural landscape here analyzed, they still interfere the mixed farms, the ones that practice agriculture, the ones that were devoted to the livestock, as well as the farms and the ranches. Another innovation is the caprinocultura developed in modern molds, using the system voisin of pasture rodízio being constituted in a pioneering experience in Brazil. Of that reality they announce other elements, to example of the establishments, being configured as new forms of use of the soil. In the perspective of turning them productive, the challenge resides of overcoming the difficulties in them existent. The reality of the space in screen is replete of lacks in all the instances. It is inferred that the municipal district possesses an enormous potential, however the performance of the administrative components is seen as deficient. He becomes urgent that the municipal public power promotes changes, mainly in what it respects to the social area, with a better attendance to the rural communities, for them to act positively in the process of the development of this municipal district

Percepção Ambiental: Areado - o olhar do povo, a visão da ciência

The objective of this research is to know the conscience, the sensibility and the interperformance's vision man-environment of some residents from Areado's slum, theirs attitudes and motivations to link individual and collectively with their environment seeking ransom the diferences and compare them in relacion of an scientific look. The study to the valorization of experience from individual or from the group consisted of humanist approach of Geography having the phenomenology as underlying philosophy. The theorical formulations manifested from ideas whole, detaching the effort to discipline the use at least these concepts: landscape, space, place and environment. Opposite the importance of knowing the interelation manenvironment, we insert more two concepts: topofilia (felling joins people to the place where they lives) and topophobia, because our preoccupations in the ambit of evironmental question, immediate to the human beings. The research had been developed from interview and percepition workshop, when the interviewed people answered about they understand what are environiment and Areado's environment. The gotten results allow a reflection about the evironmental thought thinking found there, constituting in subsidy to programs of evironmental education that be worried about local problems

Modelagem de vulnerabilidade de sistemas ambientais no municípo de Guadalupe/PI

In the Guadalupe city, with the arrival of the Boa Esperança Hydroelectric, the landscape of the municipal district lived important transformations. Those transformations continue growing today, now together with new vectors of territorial ordering, especially the agricultural industry. In front of the context of stability-instability of the environmental systems, it original of its natural vulnerability to the instability and of the transformations in the territorial dynamics of Guadalupe, the present research it analyzed and it mapped that municipal territory with relationship to the degrees of vulnerability of the environmental systems. Therefore, working a leaning methodology in a systemic perspective of the landscape and in the geoprocessing technique, the dissertation showed with thematic mapping, the most vulnerable and less vulnerable parts of the municipal district of Guadalupe, looking for a strategic vision of the problem.

Proposta de zoneamento geoambiental do município do Crato/CE

The geo-environmental zoning is an important means to plan the management of the territory, once it is the result of integration of different elements of the physical environment. The Municipality of Crato has a diversity of geo-environmental systems due to its complex landscape, which characterization and delimitation will contribute to the most appropriate occupation and the fewer prejudicial to municipal area. This study, which was supported by geo-systemic theory, searched to reach the following objectives: to elaborate a proposal of geo-environmental zoning; to characterize identified and demarcated geo-environmental systems, including their potentiality and limitations of land use and human occupation; and to generate a database on digital maps through GIS Geographic Information System. Four geo-environmental systems were identified (Chapada do Araripe: plateau and hillside, Massif and residual crest, Sertão of peripheric southern depression and fluvial Plains) and ten geo-environmental subsystems (Eastern plateau covered by cerradão/cerrado, Western plateau covered by cerrado/carrasco, Northern-west hillside, central residual Massif, Northern Residual Massifs, Sertaneja depression dominated by sedimentary materials, Sertaneja depression dominated by embasement crystalline material; wet fluvial plains and dry fluvial plains). The identified system and subsystem are similar to those proposed by FUNCEME in spite of some changes due to the more detailed mapping

Dinâmica do uso e ocupação do solo no litoral de Macau-RN no período de 1978 a 2008

This study was developed in the northern coast of the city of Macau, a total area of 88,52 km², located in the State of Rio Grande do Norte. It presents relatively plain surface, with interlaced of streams and gamboas, characterized by contributions of oceanic water, flooding areas of swamps. Altogether, the climatic and topographical conditions provide an ideal environment for the development of saline activity. Inserted in the geologic context of the Potiguar Basin, the region presents favorable conditions for the production of hydro-carbons. It still presents natural conditions for shrimp breeding and artisanal fishing. This work analyzes the transformations occurred in the land use, using air photographs of 1978, Landsat 5 ETM Images of 1988, 1998 and 2008. A secular analyzes was carried through the dynamics of the use of the territory and the transformations occurred in the landscape due to the increment of the productive activities. In the survey of the data for study of the area, it was verified that little alteration occurred in the 30 years. The saline activity that was present since the year of 1978 having an increase of about 5% in thirty years; the shrimp breeding activity that had its presence in the decade of 1990, presented a high growth in the land use, therefore in 1998 it presented 0.45% and currently it presents 6.59%. In the field it was observed that great areas used previously for the saline activity, today it is prepared for shrimp breeding and that the areas of petroleum exploration occupy salt mines, beaches and trays. In 1988 it presented a percentage of 0, 07% and currently it occupies 0.46%, having grown 50% in the last 10 years. Although the variation of the occupation of the area has been little expressive, shrimp breeding showed a growth of 1,200% in only 10 years. In regards to petroleum activity, there wasn t any demonstration of an increasing impact in the land use in the area of study in 26 years of exploration

Sobre pedras, entre rios: modernização do espaço urbano de Caicó/RN (1950/1960)

thèse de maîtrise, qui a été idealizée et exécutée à partir de la réunion et les relations dialogiques établies entre la géographie et l'histoire, et l'espace et le temps, a considéré l'environnement urbain comme le thème général et, comme la référence empirique, l'espace urbain de Caicó, incrusté dans les terres semi-arides du Sertão do Seridó Potiguar, plus précisément à la mi-sud de l'État du Rio Grande do Norte. Dans cet espace, à travers de recherche des fragments de mémoires acquis de diverses sources historiques, on a tenté de faire des investigations sur les transformations urbaines qui ont eu lieu dans la ville au cours des années 50 et 60 du XXe siècle. Ces transformations, dans l espace urbain de Caicó à un moment du pic de l'activité de développement de coton, reflétaient et conditionnaient les propres projets de modernization urbaine qui représentants des élites locales eurent conçu avec l'objectif de la construction d une ville idéal dans les regions isolées du Seridó: moderne, civilisé, progressive et capitale régionale du Seridó. Pour cette construction, les nouveaux équipements et services urbains ont passé du plan imaginaire à l espace réel, installés dans plusieurs quartiers de la ville en transformant le paysage urbain. Face à cette situation, cinémas, magasins, station de radio, énergie électrique, institutions de l'éducation, téléphonie, maison de soins infirmiers, usine de bénéficiement de coton, banques, politiques urbaines, hygiéniques et sanitaires, modes de comportement, sociabilités urbaines distincttes, parmi d'autres éléments géographiques se sont institués à travers la réalisation de certains idéaux de progrès social et dans un esprit de modernité urbaine, dans de nouveaux espaces et pratiques inventés, tramés et éprouvés sur les rochers et entre le cours d eau au milieu d'un quotidien urbain marqué par ruptures et permanence de certaines coutumes et habitudes antiques et de certains paysages et environnement ridé

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

Fotografia e paisagens da modernidade : Currais Novos/RN de 1950 a 1980 / Gênison Costa de Medeiros

This dissertation promotes a dialogue between visual representation and the new cultural geography theory to critically examine the photography representation of an specific urban landscape. The interest here is to explore the ways in which the images of the city of Currais Novos - RN, captured by the photographer Raimundo Bezerra from 1950 to 1980, have taken a great part in shaping people s understanding and imagination of this city s modernizing process. What comes out of this work is the comprehension of that photography permites a geographical study of urban landscape as it can revel perceptions, imaginations, discourses e subjetivities which are based on especific urban cultural dreams and aspirations related to the case studied. So, the aim of this dissertation was to analyse how the discourse of modernity could be seen as part of and impregnated to the urban landscape of Currais Novos by Bezerra s photographs. Then, an intertextual, hermeneutic and phenomenalogical understanding of the geographic object and how it fits within the cultural context was fundamental

A construção e estruturação do território comercial no bairro Alecrim Natal/RN

The study done has as objective the comprehension of the constructed territorial spaces through the commercial perspective, because it is a social practice which enables the dynamic of the space and the appearing of territories. Related to the territory, we emphasized the interest for the idea of used territory treated by Milton Santos, because we agreed with him believing that is the use of the territory which warrants its legitimacy. Then, the spatial dimension chose concentrates itself into the district of Alecrim, localized at the east zone of Natal/RN, where it is recognized by its strong commercial dynamic which was built during years, facing some events which happened in the context of the city. However, this dynamic counts with a hard dichotomy which involves as the considered by the State formal activities, as the informal one. About the commerce of the district, it has characteristics into its activities whose make him to be considered popular, as by the existing products, as by the strong presence of informal workers that constitutes the district s landscape. The informal workers practice expresses one of the multiples constructed alternative territorialities. We believe that this fact has direct relation with the growing process of the exclusion from the formal jobs market. Still talking about the spatial dimension, this real example of the Alecrim district shows how the techniques changes, together with the capitalism process, may influence one entire spatial dynamic across years, involving many agents, since the transient people from somewhere, until the State. Shall the Geography understand the multiple forms from the space, face to the relations that occur into it and also how new territories have been built

Inferência geográfica para delimitação de corredores ecológicos: um estudo de caso para a Mata Atlântica do município de Tibau do Sul/RN

The Atlantic Forest biome occupies much of the Atlantic coast of Brazil, in addition to portions of Paraguay and Argentina. Due mainly to its biodiversity which falls in the group of global hotspots, i.e., areas that have high priority for conservation. Although currently there are some available devices that assist in their protection in the course of the history of occupation and exploitation of the Brazilian territory, this biome has gone, and is still going through, an intense process of devastation, caused mainly by the pressure from economic activities, culminating in a significant reduction of its area and consequent fragmentation of the landscape, which brings with hosts a series of problems at various scales and aspects. As in most municipalities included in the reach area of the biome, the situation of forest fragmentation in Tibau do Sul / RN is quite critical, reflecting on a truly diverse landscape with broad typology of land uses. Among the alternatives aimed at the conservation of this biome include the creation of protected areas and the creation of ecological corridors, the latter being more efficient by connecting the remaining forests, increasing landscape connectivity, providing significant gains in relation to biodiversity. However, a major problem on implementation of Ecological Corridors projects is related to the selection of areas for this purpose, in this sense Geography can provide important contributions through the integrated study of landscape in the light of the geosystemic approach and the use of Geographical Information System (GIS) in order to permit assessment of reality having as a base the integration of ecological, biological and man-made aspects. Thus, this research aims to indicate potential areas and propose scenarios delimitation of Ecological Corridors in the municipality of Tibau do Sul / RN through Geographic Inference techniques in GIS platform. Therefore, the methodology adopted is based on the Geosystemic approach. From these elements were created 4 models to indicate potential areas for implementation of Ecological Corridors from the environmental perspective (potential erosion), socioeconomic (cover and land prices), legislative (areas protected by environmental legislation) and integrated (combination of environmental factors, socioeconomic and legislative), which in turn served as a basis for proposing scenarios aimed at this purpose. The results showed that all models can be quite useful in indicating potential areas for the establishment of ecological corridors, especially when based on an integrated approach between environmental and anthropogenic. The Corridors delimitation proposes shown may perform duties beyond the establishment of connectivity between fragments, since they also may have usefulness in controlling erosion and protecting fragile environments. Among the models developed, the integrated constituted itself as the best option because it enabled the interconnection of a larger number of fragments from a better use of the potentialities present in the landscape

Análise e monitoramento geoambiental da praia de Genipabu/RN

Issues concerning coastal regions, especially the beaches have sparked quite complex because studies are there that most people in the world has secured housing, mainly from the half of the last century, without concern for the natural dynamics of these environments, which have complex interactions of continental and oceanic, coastal responsible for changes in locations that can be perceived in a few years and sometimes even a few days or hours. The search took as main goal, analyze the Genipabu Beach, in the municipality of Extremoz/RN, fragile environment and rapid momentum, which has been occupied in a disorderly and unplanned. Carried out a beach monitoring through profiles beach environments: defined stages morphodynamics; realization of characterize hydrodynamic processes; identification of changes in the landscape. To this end, made necessary a survey from the bibliographic collection for theoretical and conceptual rationale. An empirical step for conducting the environmental characterization of hydrodynamics, leveling and topographic analysis of sediments (in laboratory), for observation of changes in features, influenced, and natural dynamics, anthropic action that increasingly comes taking the characteristics from the natural landscape. Underlines therefore the importance of academic studies in several areas in these environments, for setting up a coastal zoning giving public subsidies for managers for managing and planning the use and occupation of the coast in their areas

Vende-se uma vila: análise intra-urbana das vilas na Vila de Ponta Negra e no bairro de Nova Descoberta - Zona Sul de Natal

This dissertation is about low-income rental housing vilas in the South Zone in the city of Natal. Vilas are a string of houses, built privately in an urban plot of land, usually a backyard, facing a narrow street beco. This type of housing is originated in the 19th century in the Brazilian scenario. In Natal, this has become more popular since the late 1960s. This study is aimed at analyzing the urban integration of the vilas, considering that these house a low income population, vis à vis the speedy development of Natal s most economically dynamic area. The study starts with a discussion of the production of space, taking into consideration categories such as use value, exchange value, commodity and land rent. Field work was undertaken through structured interviews with dwellers of vilas in Nova Descoberta and Ponta Negra neighbourhoods. Owners of vilas were also interviewed. Data collected indicated worrisome housing conditions. Vilas, in the areas researched, are increasingly becoming unwelcome, constituting guetos in a place where landscape is changing rapidly. Gentrification is fast under way, first because of rise in rent and taxes; second because of general rise in living costs

Fragilidade ambiental da bacia hidrográfica do Rio Punaú (RN) e área litorânea adjacente

Hydrographic basins always exercised a big fascination over humankind that attracted for its scenery beauty or for its richness in natural resources, had been acting in order to modify these important ecosystems without, therefore, considering the possible consequences of these changes. The attributed importance to the coast ecosystems, in eminence to the hydrographic basin of Punaú river and adjacent areas, is had when it s verified the diversity of the ecosystems that contemplate it. Hydrographic basin in evidence in Rio Grande do Norte state, occupies an area of nearly 652.71 km², being it sited in the homogeneous micro-region Litoral Nordeste, with a regional population estimated in nearly 75,188 inhabitants, according to the Anuário Estatístico do Rio Grande do Norte 2004. The region of the researched basin is formed by seven municipal districts related as it follows: Maxaranguape, Pedra Grande, Pureza, Rio do Fogo, São Miguel de Touros, Taipu and Touros, but Maxaranguape, Rio do Fogo, Touros and Pureza have a direct participation in the basin. Basin in study have it lands evaluated according to the agriculturist aptitude by the conventionally methodology practiced in the country, having as objective, then, a compara-tive analysis between the ambient unities, Aeolian littoral and coast tray, identified in the researched area. From the characterization of the physic way of the area in study and owning the kept data, it was proceeded the integrated analysis of the structural elements of the landscape which were evidenced that the fragile areas are associated with the areas of agriculture cultivation, such as the ones of irregular occupation. About the degradation, the ambient diagnostic of the basin indicated that the equivalent to the Aeolian Littoral Ambient Unit correspond to the bigger pledging of the ambient quality, in other words, high ambient fragility, being this result due to the use and occupation of the soil, propitiating this way, vulnerability in the vegetal cover of the area, despite it disposes of a low agriculture cultivation percentage. Already in the Coast Ambient Tray, is emphasized the medium ambient fragility, despite of the high index of cultivated area. In a general way, the total area of the hydrographic basin of Punaú river and adjacent areas presented ambient impacts over the tolerance limit, indicating the necessity of a review of the practices of use and handling of the soil, reforesting of the water courses edges, control of erosion and contamination of the aqueous in the perspective to reduce the effects of the impacts due to the use and occupation of the basin in regard. The present search evaluated the ambient impacts diagnosised in the hydrographic basin of Punaú river and adjacent areas, pointing the causes and the probable consequences of the damages caused by these impacts to the basin ambient. From the analysis of these data, if was possible to become explicit how they are fundamental as key elements in the process of decision taking in the ambient questions
