Diagnóstico geoambiental com uso do geoprocessamento visando a determinação de potencialidades de uso do solo para a área estuarina do Rio Curimataú - Canguaretama(RN)

The activities developed in the coastal zone always arise the researchers interest, mainly when it is developed in fragile ecological areas, not observing the sustenable development laws. In this context, the analysis presented developed around the estuary of Curimatau river, located in the Eastern coast of Rio Grande do Norte state, integrates information provided by high resolution images of orbital remote sensing (IKONOS II, dated of July of 2003) and images of not-orbital remote sensing (Air photographs of DPU, dated of March of 1997) in a multitemporary perspective, diagnosising patterns of use and occupation, evaluating the main area´s impacts, together with the estuarian region fisiograph of Curimatau river. The use of high resolution images consequently allowed generates a precision cartography, facilitating the quantification of the evolution of the landscape and supporting decisions. Was possible yet, the definition of use areas, conservation areas and preservation areas; that were inserted in the concept of Potentialities: a fundamental element to management of vulnerable areas of the natural point of view. The information provided during the research had been stored in an Enviromental Georreferenced Data Base, constructed under the optics of Geographical Information Systems (GIS), that they facilitate the environment management Through fast access to information. The results were satisfactory, because permits the quantification of evolution of the landscape and the mapping. Beyond the geoenviromental diagnosis, was possible develop maps and matrixes that support the Rio Grande do Norte state costal Management.

Avaliação da biodegradabilidade de petróleo utilizando microrganismos isolados do estuário do Rio Potengi (RN)

The oil activity in the Rio Grande do Norte State (RN) is a permanent threat to coastal ecosystems, particularly mangroves, with the possibility of oil spills. In this context, the objective of this study was to evaluate the potential resistance of the mangrove environment of a possible spill. Were selected and isolated microorganisms degrading oil by the technique of enrichment cultures and formation of a bacterial consortium. The kinetic study of the consortium was held in rotary incubator shaken at 150 rpm and 30° C. Samples were taken at intervals of 4 hours for analysis of cell concentration and surface tension. The biodegradation was monitored using two methods of respirometry: manometric (OxiTop-C ®) and conductivimetry, where the biodegradation of oil was estimated indirectly by oxygen consumption and CO2 production, respectively. Furthermore, it was used a full 2² factorial design with triplicate at central point to the runs that used the conductivimetric methodology.. The technique of enrichment cultures allowed to obtain thirteen bacterial strains. Kinetic study of the consortium, we can showed the absence of the lag phase, reaching a maximum cell concentration of 2.55 g / L at 16 h of cultivation and a reduction on surface tension. When we adopted the methodology of OxiTop-C was detected a band indicating biodegradability (1% oil v/v), however when we used the conductivimetry methodology did not observe any band that would indicate effective biodegradation. By monitoring a process of biodegradation is necessary to observe the methodology will be adopted to evaluate the biodegradation process, since for the same conditions adopted different methodologies can produce different results. The oil-degrading isolates from soils of the mangrove estuary Potengi / RN are largely to be used in bioremediation strategies of these places, in the case of a possible oil spill, or it can be used in the treatment of waste oil generated in saline environments, since they are optimized the conditions of the tests so that the efficiency of biodegradation reach the minimum level suggested by the standarts

A reprodução do espaço da pequena produção rural familiar em Canguaretama/RN

This study aimed to explore the process of reproduction of space from the small family farm production in the municipality of Canguaretama, specifically focused on foodstuffs of plant origin, seeking to understand the changes in agrarian space canguaretamense and its impact on small family farms the last 35 years. Since colonization, during the seventeenth century, the production of space agrarian Canguaretama was founded under a structure based on large ownership and cultivation of cane sugar. Secondly, it was being built a small space reserved for food production to meet both the consumption of property, but also for local marketing. In the centuries following the changes in the capitalist system imposed a new dynamic for small food production, mostly in the early twentieth century, with processing plants and mills in the area extending toward the cultivation of sugarcane. In the second half of that century, mainly in the 1980s, the cultivation of cane sugar was encouraged to produce alcohol, which led to a further expansion of sugar cane toward the areas targeted for the production of foodstuffs. Currently, the framework of small food production differs little from the period of colonization in relation to the difficulties faced by this segment of agriculture. Thus, we have a reality based on socio-spatial inequality, and the near absence of the Government, which requires urgent implementation of public policies for the production and organization of small producers into associations or cooperatives to improve the productivity and hence in their standards of living and their families

Análise fitoecológica do manguezal e ocupação das margens do estuário hipersalino apodi/mossoró (rn brasil) a biotecnologia vegetal como alternativa para a cotonicultura

The mangrove is a coastal ecosystem of the big ecological importance, showing high fragility front by natural process and the human interventions in the coastal zone. This research has objective to analyses the relation between mangrove species distribution and geochemical parameters variation of the water and soil in Apodi/Mossoro estuary, located in the Rio Grande do Norte state north coastline. The results were obtained from floristic and structural analysis of the vegetation and Quick Bird satellite images interpretation (collected in 2006 year), manipulated with ENVI 4.3 and ArcGIS 9.2 software s. This estuary was characterized by to presents a gradient of the salinity around 40 kilometers extension, finding amount between 50 and 90 g/l-1. Will be identified the formation of the mix vegetation formation in the estuary mount, where the water salinity no show express wide variation on seawater (36 g/l-1), finding species: Rhizophora mangle L., Laguncularia racemosa (L.) C. F. Gaertn, Avicennia schaueriana Stap. & Leechman e Avicennia germinans L. Along of the estuary, have a streak formation of the vegetation composed by Avicennia spp. and L. racemosa. In high estuary, where the salinities value stay above 60 g/l-1, only A. germinans predominate in dwarf form. In this sense, the salinity is as a limiting factor of stress on the mangrove vegetation as it enters the estuary, this parameter should be taken into account when drawing up management plans and environmental restoration in the estuary in question

Melhoria da qualidade da atenção à saúde da pessoa idosa na Unidade Básica de Saúde Piquiri II, Canguaretama/RN

O aumento recente na expectativa de vida no Brasil resultante da mudança demográfica vem despertando a atenção dos gestores e dos servidores em saúde pública. O número de idosos em acompanhamento no SUS está crescendo em uma proporção maior do que o número de profissionais de saúde adequadamente habilitados para lidar com essa classe de usuário. Este projeto tem como objetivo geral melhorar a atenção à saúde da pessoa idosa no âmbito da atenção básica da seguinte maneira: ampliar a cobertura de acompanhamento, melhorar a adesão e a qualidade da atenção desses usuários, melhorar o registro das informações, mapear os idosos de risco na área de abrangência e promover a saúde. Essa sistematização foi amparada pelo uso da planilha de Objetivos, Metas, Indicadores e Ações (OMIA) e posta em prática com o preenchimento da ficha espelho e da planilha de coleta de dados durantes as atividades cotidianas. Foram cadastrados no programa apenas os usuários que foram atendidos durante as 12 semanas de intervenção. Após três meses de intervenção, foi observado um crescimento da proporção de atendimentos para idosos (de 13,2% para 20,2%), mesmo sem o cumprimento da meta inicial de cadastrar 80% dos idosos – 21,9% foram cadastrados no programa. As visitas domiciliares também aumentaram a frequência, sendo feito o cadastro de 81,2% dos idosos acamados e/ou com dificuldade de deambulação. Foi feito o rastreio para Hipertensão Arterial Sistêmica (HAS) e Diabetes Mellitus (DM) em 100% dos idosos acompanhados. Observou-se que 83,5% dos usuários tiveram acesso aos medicamentos prescritos. 100% deles receberam orientação para a adoção de hábitos alimentares saudáveis, e 68,2% foram orientados quanto a prática regular de atividade física. No entanto, as metas para o acompanhamento odontológico não foram atingidas. Ao final do período de observação, pudemos concluir que ocorreu crescimento tanto na quantidade como na qualidade da atenção direcionada aos idosos na UBS Piquiri II, mas os esforços devem ser continuados para que os resultados permaneçam em crescimento.

Os resultados do Pré-natal e Puerpério depende da implementação mais efetiva das ações de saúde, entre elas a assistência ao pré-natal adequada. Para este acompanhamento deve estar assegurado o desenvolvimento da gestação, onde a acessibilidade é importante para o prognóstico, o nascimento e a assistência precoce no primeiro trimestre para um adequado atendimento ao pré-natal permitindo o parto de um recém-nascido saudável. Foi realizada uma intervenção com objetivo de melhorar a atenção ao pré-natal e puerpério na UBS Sertãozinho I, Canguaretama /RN. Os objetivos específicos da intervenção foram: ampliar a cobertura do pré-natal e puerpério, melhorar a qualidade da atenção ao pré-natal e puerpério, melhorar a adesão ao pré-natal e puerpério, melhorar o registro do programa de pré-natal e puerpério, realizar avaliação de risco das gestantes e promover a saúde no pré-natal e puerpério. A intervenção foi desenvolvida no período de três meses com a participação de todas as gestantes e puérperas atendidas neste período, na unidade básica de saúde. A comunidade ficou mais orientada sobre a importância da prioridade do pré-natal, a organização, a qualidade de toda a documentação e a interação da equipe para desenvolver as diferentes atividades que precisaram as gestantes e puérperas. Desenvolvemos um trabalho em equipe, não de maneira individual. De fato também ajudou aos resultados alcançados a participação da família, importante na atenção primária de saúde.

Análise de sedimento de fundo: uma amostragem representativa do estuário Potengi/RN

The aim of this study is to quantify the presence of major and minor elements in the sediments of estuary Potengi. Four georeferenced sampling points were used in the study, at which sediment samples were collected in the channel of the river and on the right and left banks. In addition, dissolved oxygen, salinity and water conductivity were taken in situ at the time of sample collection. The percentage of organic matter, determined by gravimetry, and granulometric analysis of the sediment samples were conducted in the laboratory. To quantify the major and minor elements a prior test to open the sample was conducted with standard NIST 1646ª estuarine sediment to choose the best methodology to be adopted. The sediment samples were dissolved in microwaves with nitric acid and chloridric acid, according to methodology proposed by US EPA 3051ª. Quantitative analyses of the elements Al, Fe, Cd, Cr, Cu, Mn, Ni, Pb and Zn were conducted by inductively coupled plasma optical emission spectrometry (ICPOES). The results showed that the partial concentrations of the elements analyzed are below average worldwide shale levels, the standard described by Turekian and Wedepohl (1961)

Impactos Geoquímicos e Sócio-Ambientais no Estuário do Rio Potengi Região Metropolitana da Grande Natal/RN

The present work studied the problems faced riverine populations of the estuary Potengi, detaching its perception with regard to the environment, as well as in the evaluation of the institucional arrangement that acts in the place. Questionnaires were used in five riverine communities and conducted interviews with agents of public agencies and colonies of fishermen. There is little understanding of the needing to preserve and weakness in the application of the regulation mechanisms

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

Mídia impressa e meio ambiente: um estudo da cobertura da mortandade de peixes no estuário do Rio Potengi, Natal-RN

Environmental issues are becoming increasingly habitual to the media, particularly when calamities are involved. A feature of environmental disasters is that they disclose both environmental crises and the media limitation in reporting them. The research tried to contribute to the subject through the study of press media coverage of a large fish kill along an estuary in the State of Rio Grande do Norte, Brazil, in 2007. Thematic content analysis of newspaper reports identified the predominance of a superficial and denunciative coverage, lacking an educational perspective, and with little contribution to formation of a critical sense in readers. It also has identified the precarious treatment of those scientific concepts that could substantiate the actual causes of mortality of tons of aquatic fauna

Caracterização morfodinâmica do estuário do Rio Açu, Macau/RN

Estuaries are coastal environments ephemeral life in geological time, derived from the drowning of the shoreline as a function of elevation relative sea level. Such parallel systems is characterized by having two sources of sediment, the river and the sea. The study area comprises the Acu River estuary, located on the northern coast of Rio Grande do Norte State, in a region of intense economic activity, mainly focused on the exploration of oil onshore and offshore, likely to accidental spills. In the oil sector are developed for salt production, shrimp farming, agriculture, fisheries and tourism, which by interacting with sensitive ecosystems, such as estuaries, may alter the natural conditions, thus making it an area susceptible to contamination is essential in understanding the morphodynamic variables that occur in this environment to obtain an environmental license. Information about the submarine relief the estuaries are of great importance for the planning of the activity of environmental monitoring, development and coastal systems, among others, allowing an easy management of risk areas, and assist in the creation of thematic maps of the main aspects of landscape. Morphodynamic studies were performed in this estuary in different seasonal periods in 2009 to observe and quantify morphological changes that have occurred and relate these to the hydrodynamic forcing from the river and its interaction with the tides. Thus, efforts in this area is possible to know the bottom morphology through records of good quality equipment acquired by high resolution geophysical (side-scan sonar and profiler current by doppler effect). The combination of these data enabled the identification of different forms of bed for the winter and summer that were framed in a lower flow regime and later may have been destroyed or modified forms of generating fund scheme than the number according Froude, with different characteristics due mainly to the variation of the depth and type of sedimentary material they are made, and other hydrodynamic parameters. Thus, these features background regions are printed in the channel, sandy banks and muddy plains that border the entire area

Foraminíferos de manguezais do rio Curimataú (RN): estudos sinecológicos com aplicação no setor de petróleo e gás

O sistema estuarino do Rio Curimataú, uma planície lamosa amplamente coberta por vegetação de mangue e relativamente pouco impactada, foi estudado quanto à distribuição espacial da microfauna de foraminíferos e suas condicionantes. Vinte e cinco gêneros e quarenta espécies foram identificadas a partir dos sedimentos superficiais, considerando-se os indivíduos vivos e mortos presentes em 10 pontos ao longo do estuário, dos quais se extraíram ao menos 100 espécimes por amostra. O sistema pôde ser compartimentado em quatro sub-ambientes halínicos (hiperhalino, mesohalino, polihalino e euhalino), correspondentes, respectivamente, a quatro ecofácies de foraminíferos designadas de Ammotium spp., Miliammina fusca, Arenoparrella mexicana e Ammonia spp. Cada um destes segmentos ambientais foi caracterizado segundo os padrões de riqueza, diversidade e equitatividade das espécies. Os resultados deste estudo poderão servir para comparações a serem feitas com outros estuários tropicais modernos (impactados antropicamente ou não) e antigos. Tem aplicação, portanto, no setor de petróleo e gás, sendo de interesse às atividades de gestão ambiental de áreas litorâneas e de investigação da história geológica das bacias sedimentares
