Cara e coroa: O PRONAF B e os impactos na ocupação rural do município de Ceará-Mirim

The present work deals with study on the National Program of Reinforcement of Familiar Agriculture, Group B, referring it offers of agricultural credit the agriculturists who possess familiar prescription until R$ 2,000, 00, and its impact in the agricultural occupation of the city of Ceará-Mirim. From theoretical referencial regarding the agricultural occupation, it collects of data, application of questionnaires between the beneficiaries of PRONAF B and interviews with the involved actors, it was made possible ascertainment of the hypothesis of that the program in this modality of credit, is capable to provide only to the maintenance or diversification of the occupation in the familiar unit and not it generation of remunerated occupation not familiar. This research disclosed to the diverse possibilities of use of the credit and its impact in the agricultural occupation, exactly when it is deviated for other purposes not waked up next to the financial institution, generating impacts not waited, however positive. When destined to the waked up end, still new forms appear of way occupation to complement it the deriving familiar prescription of the main activity. Unable to discard the rise even though very small and informal, non-family gainful occupation. The knowledge is added of that exactly ahead of the easinesses of access to the social base of the program, many familiar agriculturists still find difficulties in the approval of the which had credit, on the other hand, the requirements of the financial institutions

A história local e seu lugar na história: histórias ensinadas em Ceará-Mirim

This Researchis about history education and is directed toward the understanding of teacher practices in schools of the basic education in Ceará-Mirim, a city located in the state of Rio Grande do Norte. Its purpose is to understand the approaching forms of local history in 5ª to 8ª grade classrooms in the light of the recent innovations in the fields of the historiografy and education. The study was done with a view of investigating local history is being taught by teachers, as well as reflecting on the necessary conditions to the accomplishment of a teaching whose know how to make possible to break, on the one hand, with the limits of the narrow `local view`, and, on the other hand, with the globalized view, negating the local particularitities and especifications. Such questions had emerged as the understanding of what local history contents can constitute in a significant component in the production of school historical knowledge in 5ª to 8ª grade classrooms. History education is analyzed, considering the depositions of three teachers of Ceará-Mirim in reagard to its historiography conceptions and history as a school subject. This inquiry is of a qualitative nature and had as a main strategy of data construction from the interviews with the teachers. The analysis indicates the permanence of teacher practices who, even though presenting innovations, bring an implicit value hierarchy where the place or thematic places are not contemplated in the school contents or appear overwhelmed by general history and the Brazilian history, configuring itself as a hierarchical relation to problematic historical ones. Thus the necessity of having historical school knowledge, that considers the local especifications, without, however, ignoring the articulations with other spatial dimensions

Patrimônio, Memória e Espaço: a construção da paisagem açucareira do Vale do Ceará-Mirim

This work aims to understand how the installation of sugar culture along the river Ceará-Mirim defined the spatial organization of the Valley, and thus setting the landscape. This space has begun to be defined only in the second half of the nineteenth century, when the sugarcane growth had atarted on land located on the banks of the river Ceará-Mirim. The passage of this period of great prosperity can be seen through the heritage material which is still presented in the region. Walking through the Valley, we found a considerable number of architectural buildings, many in ruins, linked to this historical moment. This perception, caused by these buildings, will take us on a trip to the past, back to a time characterized by great-houses, mills, sugarcane plantations, planters, slaves, etc. The references that lead us to consider the sugar mills located along the valley of Ceará Mirim as a patrimony, which carry an entire historical baggage, guide us to the first half of the twentieth century. During this period, the role of intellectuals from the Rio - Sao Paulo through the modernist movement will be decisive in the formation of a national identity. The heritage material identified along the valley of Ceará Mirim defined its current spatial organization, setting the landscape. But we must conceive this landscape into two ways: first, as a material representation of social practices carried out in this space, where social, cultural, economic and environmental aspects have interacted to their training; as well as a landscape that carries a whole historical baggage which was built throughout the twentieth century

Análise da degradação ambiental das áreas de preservação permanente localizadas no estuário do rio Ceará-mirim/RN

The purpose of this paper is to identify and analyze the main environmental impacts taking place in the permanent preservation areas located in the Ceará-Mirim River estuary/RN and its surrounding areas. For that, the study was divided in two chapters, structured in the shape of a scientific paper. The first is a theoretical proposition on the occupation of the APPs in light of the discussion of the geographic space and the sustainability of the development, where a bibliographical review was made emphasizing the production of the geographic space, the sustainability of the development and the permanent preservation areas. In the second chapter, from a systemic approach, geoprocessing techniques and the adaptation of the Pressure-State- Response Indicators System were used, the latter being developed by the Organization for Economic Co-operation and Development OECD. Therefore, from the methodological approaches used, it's been observed that the use of permanent preservation areas for purposes other than those determined in the legislation and, mainly guided by capitalist interests, leads to the environmental degradation of these areas, fact which has been confirmed in the empiric study conducted in the second chapter, where it was possible to identify a series of environmental impacts such as: deforestation of mangrove and riparian vegetation for carciniculture implantation, the devastation of dune areas caused by the urban expansion in the coastal stretch and siltation of fluvial channel

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

Geografia, turismo e meio ambiente: uma nova face do litoral dos municípios de Extremoz e Ceará-Mirim

La presente pesquisa contempla reflexiones referentes de la actividad turística en la organización socio-espacial en el litoral de las comarcas de Extremoz y Ceará-Mirim, región de la Grande Natal. Nuestro objetivo principal es el estudio de las transformaciones del espacio y de sus implicaciones socio-ambientales en curso en el proceso de producción del espacio turístico en el litoral de las referidas comarcas desde 1997 hasta 2007, momento de importancia publica-privada que, a partir del PRODETUR, tuvo la base para el incremento de las potencialidades turísticas. En este sentido, varias fueron las técnicas para una mejor compresión de las aspiraciones y de la percepción de los actores envueltos con la actividad turística (comerciantes, turistas, populación y poder publico local) para conocer cuales son sus consideraciones en cuanto a los cambios que proceden de la implantación de la actividad turística en el lugar, cuanto a la mejora de la calidad de vida, de la generación de empleo y de renta, comercialización, conservación, preservación del ambiente, cumplimiento de la legislación, afirmación cultural así como las acciones puestas en ejecución en las comarcas. Para tal necesidad, se buscó analizar los datos estadísticos a partir del uso de los cuestionarios con preguntas estructuradas y semi-abiertas como instrumento de colecta de información que les era correlacionada con la opinión de los actores locales de modo que podamos formar y entender los elementos básicos que son parte de los espacios turísticos en foco. Fueran utilizadas fotografías aéreas de las comarcas de Extremoz y Ceará-Mirim, provistas por el IDEMA, con la intención de percibir acerca de los cambios del espacio y las implicaciones socio-ambientales de la área en estudio. Concluimos en función de los resultados que el modelo de Turismo concebido por lo Brasil, estimulado y financiado por lo Gobierno Federal, está insertado en el contexto de la economía global y, por lo tanto, el Estado del Rio Grande del Norte, en específico los espacios litoraneos de las comarcas de Extremoz y Ceará-Mirim, que poseen características similares a este modelo, con sus particularidades, que si traduzca por la exclusión social, formas de apropiación privada de los espacios público y áreas de protección ambiental como las playas, las dunas y las lagunas, el desacato o no el cumplimiento de la legislación ambiental, aumento de las desigualdad de renta en una región que posee una problemática social grave y sin inversión, implantación de la infraestructura, ausencia de política pública local, donde los intereses económicos son prioridad delante de las aclamaciones populares. Se sugiere un repensar cuanto al modelo actual de desarrollo adoptado, que el planeamiento sea pautado en base a la participación integrada de los varios agentes implicados con la actividad turística, incluyendo en la medida del posible, las aspiraciones de la población local como precusoras de sus reales necesidades, donde esta acción interactiva contestará ciertamente en un esfuerzo significativo en la construcción de un nuevo paradigma, modelo del desarrollo sustentable, siendo posible superar gradualmente el incremento de la pobreza, de la exclusión y de los impactos ambientales, donde la calidad de vida sea factor fundamental

Entre veados, carneiros e formigas: conflito pela posse de terra na ribeira do Ceará-Mirim, e concepções de mentalidade possessória, 1725-1761

Shaping the Luso-Brazilian space in Portuguese America was through constant conflicts between different individuals and institutions. Regarding to land ownership, such conflicts were aggravated, depending on the individuals involved and their context. The captaincy of Rio Grande, there is conflict over land ownership Cidade dos Veados and Olho d' Água Azul and its stakeholders: priests of the Society of missionaries of the village Guajiru; indian mission Guajiru; and members of Carneiro da Cunha family. In 1725, the jesuit mission Guajiru requested a league of land at a place called Cidade dos Veados for the indians of his mission claiming that the land that the mission had was not sufficient for the subsistence of the same. In 1727, priest requested another league of land in place Olho d'Água Azul, stating that the mission had more than 192 couples. Both lands were properly required for the mission guajiru. however, in 1760, with the changes imposed by the indian directorate ombudsman responsible for investigating indigenous possessions realized that the indians did not occupy the two lands requested in the 1720s , due to the fact João Carneiro da Cunha has taken possession of the same. As a result, the impasse over land are ligth. This conflict over land ownership Cidade dos Veados and Olho d'Água Azul, we intend to highlight in particular the motivations and mindsets about possessory property of each party involved. We seek to understand the motivations of each group involved allowed the use of specific strategies and set out to try to take possession of the lands of the Cidade dos Veados e Olho d'Água Azul

Segurança alimentar e nutricional dos agricultores familiares da associação dos produtores e produtoras orgânicas de Ceará Mirim/RN

The proposition of this research is supported by the definition of Food Safety and Nutrition (FSN), established by the II FSN National Conference. Taking this concept as reference, the research instrument aimed to analyze strategies and actions related to FSN, developed by members of Ceará Mirim Organic Producers Association, located in Rio Grande do Norte state (Brazil), from aspects related to family feeding, as well as means of access, quantity and food culture. It was aimed to answer the following questions: Do the families benefited from Ceará Mirim Organic Producers Association have strategies that assure their FSN? If so, do these strategies originate from public policies or own actions? Do these strategies focus on family revenue? In expenses with food and proper feeding? How do these strategies articulate together and which social networks do they form? In this research, there were also approached questionings which comprise market opening through the declaration of the products as Organization of Social Control (OSC), aggregate value and participation in agroecological fairs, aiming to identify and characterize if these strategies contribute for Food Safety and Nutrition of these families. The data here analyzed were obtained from semi-structured interviews, conducted in the production sites of each farmer, and have a qualitative approach. 21 questionnaires were applied to the family farmers, in seven projects of agrarian reform settlements (Carlos Marighella, Nova Esperança II, Aliança, Marcoalhado I, Santa Águeda, Santa Luzia and União). From this study, it was concluded that most of FSN strategies result from a series of distinct public policies, which potentiate the existing strategies and create new ones, such as in the case of organic production, which is the main motivation, even for the organization of the studied group. These strategies brought improvements in feeding and caused changes in eating habits, especially in the diversification of production for own consumption. This, on the other hand, is assuring greater food autonomy and increasing marketing channels, through fairs or institutional markets. It was also verified that reciprocity relations increased after the organic production, and they are indispensable to assure food in difficult times, also contributing to incentive organic production itself, through supplies exchange.

Dinâmica de expansão urbana de Ceará-Mirim-RN: aspectos locais e metropolitanos?

This study aims to understand the growth dynamics of Ceará-Mirim city considering the aspects that define its current urban sprawl. We chose to use as methodological approach the concept of space as a product and producer of social relations and the same constitutes by objects and actions that relate in a dialectical process over time. As a research tool, it took place bibliographical study that features the historical aspects of use and occupation, in order to evidence the regional ground agents that explain its current urban setting. Then, it was collected a secondary data of economic analysis activities from municipality and their impact on local social structure. Between these aspects, the sugar economy, even in decline, had appeared as defining the boundaries of urban growth. At the regional scale, other factors were discussed in a way of urban influence processes forming the Greater Natal (RMNatal), and Ceará-Mirim appears integrating into this scale in a very low level according to Metropolis Observatory (2012). However, we have pointed out that in recent years, especially in growth vector of BR 406, settled metropolitan scope equipment. These objects have been associating in a real estate sector's reasoning while the possible "metropolization" have been promoting as investments in the city's expansion area.

Condicionamento estrutural das zonasa de cisalhamento da região de Forquilha, domínio Ceará Central: uma abordagem integrada de sensoriamento remoto e geologia estrutural

The studied region, named Forquilha and localized in northwestern Central Ceará domain (northern portion of Borborema Province), presents a lithostratigraphic framework constituted by paleoproterozoic metaplutonics, metasedimentary sequences and neoproterozoic granitoids. The metasedimentary rocks of Ceará group occupy most part of the area. This group is subdivided in two distinct units: Canindé and Independência. Canindé unit is represented basically by biotite paragneisses and muscovite paragneisses, with minor metabasic rocks (amphibolite lens). Independência sequence is composed by garnetiferous paragneisses, sillimanite-garnet-quartz-muscovite schists and quartz-muscovite schists, pure or muscovite quartzites and rare marbles. At least three ductile deformation events were recognized in both units of Ceará group, named D1, D2 and D3. The former one is interpreted as related to a low angle tangential tectonics which mass transport is southward. D2 event is marked by the development of close/isoclinal folds with a N-S oriented axis. Refolding patterns generated by F1 and F2 superposition are found in several places. The latest event (D3) corresponds to a transcurrent tectonics, which led to development of mega-folds and several shear zones, under a transpressional regime. The mapped shear zones are Humberto Monte (ZCHM), Poço Cercado (ZCPC) and Forquilha (ZCF). Digital image processing of enhanced Landsat 7-ETM+ satellite images, combined with field data, demonstrate that these penetrative structures are associated with positive and negative geomorphologic patterns, distributed in linear and curvilinear arrangements with tonal banding, corresponding to the ductile fabric and to crests. Diverse color composites were tested and RGB-531 and RGB-752 provided the best results for lineament analysis of the most prominent shear zones. Spatial filtering techniques (3x3 and 5x5 filters) were also used and the application of Prewitt filters generated the best products. The integrated analysis of morphological and textural aspects from filtered images, variation of tonalities related to the distribution of geologic units in color composites and the superposition over a digital elevation model, contributed to a characterization of the structural framework of the study area. Kinematic compatibility of ZCHM, ZCPC, ZCF shear zones, as well as Sobral-Pedro II (ZCSPII) shear zone, situated to the west of the study area, was one of the goal of this work. Two of these shear zones (ZCHM, ZCPC) display sinistral movements, while the others (ZCSPII, ZCF) exhibit dextral kinematics. 40Ar/39Ar ages obtained in this thesis for ZCSPII and ZCPC, associated with other 40Ar/39Ar data of adjacent areas, indicate that all these shear zones are related to Brasiliano orogeny. The trend of the structures, the opposite shear senses and the similar metamorphic conditions are fitted in a model based on the development of conjugate shear zones in an unconfined transpression area. A WNW-ESE bulk shortening direction is infered. The geometry and kinematic of the studied structures suggest that shortening was largely accommodated by lateral extrusion, with only minor amounts of vertical stretch

Estrutura e dinâmica do fitoplânctone bacterioplâncton em cultivos de camarão no Rio Grande do Norte-Brasil: impacto sobre o ambiente natural

This work aimed to study the structure and dynamic of Phytoplankton and Bacterioplankton in a complete cycle of shrimp cultivation (Litopenaeus vannamei) and determine the environmental factors responsible for the structural changes of these communities. The study was realized in a saltwater shrimp farm (Macaíba, RN), between September/2005 and February/2006, and in a freshwater shrimp farm (Ceará Mirim, RN), between May/2007 and September 2007. The samplings were collected weekly in saltwater farm and every fifteen days in freshwater farm. Total phosphorus, chlorophyll a and environmental parameters (pH, dissolved oxygen, salinity, temperature, depth and water transparency) were measured. Qualitative and quantitative analysis of the phytoplankton and bacterioplankton were carried out. The Shannon-Wiener ecologic indexes of diversity and the Pielou equitability indexes were calculated to the phytoplankton. Bacterial density was determined by epifluorescence microscopy. The data were statistically analyzed by Pearson correlation and t-Test. Chlorophycea were predominat in salt water and in the captation/drainage point (24 to 99%). Diatoms had higher wealth. The species Choricystis minor had the highest occurrence (100%) and dominance (90-100%), thus showing its adaptation to the high temperatures, salinity and low water transparency conditions. Filamentous Cyanobacteria like Oscillatoria sp., Pseudoanabaena sp. and Phormidium sp. had constant levels. The negative correlation between chlorophycea and water transparency, and the positive correlation between chlorophyll a and salinity, showed that the phytoplankton was well adapted to the low transparency and to the high salinity. The bacterioplankton was negatively correlated with the total phosphorus and salinity. In freshwater, Cyanobacteria were predominant (>80%), presenting some producers of toxins species like Microcystis sp., Aphanizomenon sp., Cylindrospermopsis raciborskii e Anabaena circinalis. Cyanobacterial density and total phosphorus and chlorophyll a concentrations exceeded the maximum value allowed by legislation. The means of total phosphorus varied from 264 to 627 Wg.L-1 and the means of chlorophyll a oscillated between 22 and 182 Wg.L-1. The phytoplankton species were selected by low availability of the light, high pH, temperature and high availability of total phosphorus. The bacterioplankton showed high densities (5,13 x 107 to 8,50 x107 Bac.mL-1). The studied environments (ponds and rivers) presented a high level of trophic state based on the high concentrations of chlorophyll a and total phosphorus and cyanobacteria dominance. The composition of species in the ponds and rivers was similar, as well as high concentrations of total phosphorus and chlorophyll a, highlighting the pollution caused by the discharges of the farms in natural environment

Síntese e caracterização de peneiras moleculares mesoporosas do tipo MCM-41 e AlMCM-41 a partir de fontes alternativas de sílica e de alumínio

The mesoporous molecular sieves of MCM-41 and AlMCM-41 type are considered as promising support for metal in the refining processes of petroleum-based materials as catalysts and adsorbents for environmental protection. In this work the molecular sieves MCM-41 and AlMCM-41 were synthesized by replacing the source of silica conventionally used, for quartz, an alternative and abundant, and the use of waste from the production of diatomaceous earth, an aluminum-silicate, as a source aluminum, due to abundant reserves of diatomaceous earth in the state of Rio Grande do Norte in the city of Ceará-Mirim, with the objective of producing high-value materials that have similar characteristics to traditional commercial catalysts in the market. These materials were synthesized by the method of hydrothermal synthesis at 100 º C for 7 days and subjected to calcination at 500 º C for 2 hours under flow of nitrogen and air. The molecular sieves were characterized by X-ray diffraction (XRD), differential thermal analysis (DTA) and thermogravimetric analysis (TG), adsorption of N2 (BET and BJH methods), spectroscopy in the infra red (FTIR), microscopy scanning electron (SEM) and transmission electron microscopy (TEM). The analysis indicated that the synthesized materials showed characteristic hexagonal structure of mesopores materials with high specific surface area and sort and narrow distribution of size of pores
