Estudo da dinâmica costeira da região da foz do rio Piranhas-Açu para geração de mapas de sensibilidade do litoral ao derramamento de óleo

The study area is located in the northern coast of Rio Grande do Norte State comprising the mouth of Açu-Piranhas river including the cities of Porto do Mangue e Areia Branca. The local geological setting comprises Cretaceous, Tertiary and Quaternary geological units of the Potiguar Basin. One is about a region of high morphologic instability due to action of the rigorous dynamic coastal processes, beyond the intense human activities mainly for the performance of the petroliferous industry, salt farms and tanks of shrimp industry.For the accomplishment of this work Landsat 5 TM and Landsat 7 ETM + from four distinct dates were used as cartographic base, in which one applied techniques of digital processing to elaborate thematic maps of the existing natural resources to support the geologic and geomorphologic characterization and the soil and landuse maps. The strategy applied was the interpretation of multitemporal images from aerial and orbital remote sensors alIied to the terrain truth recognition, integrated through a Geographic Information System. These activities had alIowed the production of Sensitivity Maps of the Coast to Oil Spilling for the area, on the basis of the Coastal Sensibility Index. Taking into account the seasons were created maps to distinct datas: July 2003 represents the winter months that presented a sensibility lower when compared with the month of December 2003. For the summer months greater sensitivity is due to the hydrodynamic data that suggest a lesser capacity of natural cleanness of the oil and its derivatives in spilling case.These outcomes are an important and useful database to support an assessment to a risk situation and to taking decision in the face of an environmental disaster with oil spilling in coastal area, alIowing a complete visualization of the area and identifying all portions in the area with thei environmental units and respective Coastal Sensibility Index.

Análise de vulnerabilidade ecológica da Bacia Lagos São João, RJ: uma contribuição metodológica para estudos de adaptação às mudanças ambientais globais.

Este trabalho objetiva contribuir para o desenvolvimento de metodologia de análises de vulnerabilidade ecológica de bacias hidrográficas, com foco nos ecossistemas de água doce. Partiu-se de uma base metodológica proposta pela Rede WWF e de sua adaptação para a Bacia Lagos São João. Através da aplicação da metodologia desenvolvida, foi possível realizar uma análise multicriterial que identificou, por um lado, os principais estressores afetando a integridade ecológica da bacia, e sua severidade e frequência, mediante avaliação colaborativa de um painel de especialistas; por outro lado, avaliou-se a sensibilidade da bacia aos estressores selecionados. O uso de ferramentas de sistemas de informação geográfica permitiu espacializar, localizar e quantificar as ameaças (estressores), gerando mapas de risco ecológico, identificando em especial, as unidades mais desequilibradas do território em análise. Estas são indicadas como prioritárias para as ações de conservação dos ecossistemas aquáticos, e dos serviços ecossistêmicos providos, do qual depende grande parte da população da bacia. Esta dissertação apresenta, portanto, duas principais contribuições: um estudo global e preliminar da integridade ecológica da bacia Lagos São João; e, sobretudo, adaptações e detalhamentos da base metodológica desenvolvida pela Rede WWF, replicáveis em outras bacias hidrográficas. Ressalte-se que esta análise constitui etapa preliminar para a definição de estratégias de adaptação e resiliência de bacias hidrográficas às mudanças ambientais globais associadas às variabilidades e mudanças climáticas.

Análise da vulnerabilidade socioambiental na Zona de amortecimento do Parque Estadual do Ibitipoca (MG), por geoprocessamento: contribuindo no apoio à tomada de decisão.

Conservar as últimas florestas tropicais é uma preocupação mundial, e como formas de proteção legal são criadas Unidades de Conservação (UCs), dedicadas para a preservação e manutenção da biodiversidade e recursos naturais. O entorno das áreas protegidas também são locais amparados pela lei e as atividades nelas devem ser restritas, a fim de não gerar impacto sobre a UC. O Parque Estadual do Ibitipoca, localizado em Minas Gerais, possui uma zona de amortecimento (ZA) de 100,41 km que pertence aos municípios de Lima Duarte, Santa Rita do Ibitipoca e Bias Fortes. O presente trabalho, portanto, visa caracterizar a vulnerabilidade socioambiental na zona de amortecimento do Parque Estadual do Ibitipoca (PEI), utilizando para tal, técnicas de geoprocessamento. Para chegar ao resultado final foi feito uma análise da vulnerabilidade social da ZA, utilizando dados do censo de infraestrutura (água, esgoto e lixo) e renda per capita; e para a vulnerabilidade ambiental foi realizado a sobreposição dos mapas de uso da terra, declividade e tipos de solos. Esses dados foram tratados no programa ArcGis, através da análise multicritério e seguindo a metodologia proposta por Moura (2007). O mapa de vulnerabilidade socioambiental possibilitou apontar os locais que necessitam de maiores cuidados e investimento, auxiliando assim os gestores do Parque no manejo e preservação da ZA. Os processos adotados nesta pesquisa permitiram a geração de um banco de dados georreferenciado, que será disponibilizado aos gestores, à população do entorno e à comunidade técnico-científica.

A Problemática da Erosão Costeira: O Caso Específico da Praia do Pedrógão

Ao longo das últimas décadas, tem-se verificado uma crescente ocupação populacional e urbanística, em paralelo com a concentração de diversas actividades económicas, ao longo das zonas costeiras. Neste sentido, torna-se fulcral o desenvolvimento de políticas de gestão integrada destes ecossistemas naturais, dada a sua grande vulnerabilidade, no que respeita aos usos e ocupação do solo. Como resultado de acções naturais e do Homem (na sua grande maioria), a erosão estabelece-se como o principal problema que assola as zonas costeiras, em Portugal. Neste sentido, as Tecnologias de Informação Geográfica, em especial os Sistemas de Informação Geográfica, conferem-se como importantes ferramentas, tanto na monitorização do litoral, como no apoio aos processos de tomada de decisão. A presente dissertação detém, como principal objectivo, demonstrar as mais-valias dos SIG no estudo das zonas costeiras, especialmente na área da prevenção. Tendo como área de estudo a praia do Pedrógão, em Leiria, considerando o período temporal 1947 – 2014 (1947-1983; 1983-2003; 2003-2007; 2007-2012; 2012-2014), propõe-se: estabelecer uma base cartográfica que analise, espacialmente, o comportamento da linha da costa face à gradual erosão; quantificar as taxas de erosão/acreção e, por fim, proceder à delimitação de faixas de perigo, em paralelo com a análise dos resultados previamente conseguidos, assim como da topografia do local em análise. Para o troço costeiro seleccionado, é de constatar que existe, efectivamente, um recuo da linha da costa, especialmente na praia Sul (Praia dos Campistas), onde se regista o maior recuo médio anual (-17.72m, entre 2012-2014). Na praia Norte, as v taxas anuais variam entre os -0.64m (1947-1983) e os -15.07m (2012-2014), tendo apresentado valores de acreção, com excepção para o intervalo de tempo mais recente. É certo que as recargas de areia, iniciadas em 2011, procuram minimizar os impactos da erosão, o que pode condicionar os resultados obtidos. Por outro lado, no que respeita às faixas de perigo, é certo que, com o recuar da costa, há uma tendência da frente urbana aproximar-se do nível de “perigo muito elevado”. Nesse sentido, a grande maioria do edificado situa-se na faixa de perigo moderado (211 edifícios), constatando-se que outra grande parte (193 edifícios) não se encontre ameaçado. De um total de 413 edifícios, apenas 1 encontra-se em perigo elevado. Mantendo-se esta tendência de recuo da costa e tendo por base o trabalho de campo efectuado, estima-se que os valores apresentados venham a alterar-se, isto é, tanto a população local, como o edificado tendem a aproximar-se do perigo máximo/elevado.

A mineração na porção média da Planície Costeira do Rio Grande do Sul : estratégia para a gestão sob um enfoque de gerenciamento costeiro integrado

A porção média da Planície Costeira do Rio Grande do Sul constitui-se numa região crítica em termos de planejamento de uso devido a uma estreita conjunção de fatores de ordem econômica, ambiental, social e histórico-cultural, estabelecida, em princípio, pela presença de um importante complexo estuarinolagunar. Nessa área, bem como no restante da zona costeira do Brasil, as diretrizes para o uso sustentável dos recursos naturais estão materializadas em leis e programas governamentais, dos quais o Plano Nacional de Gerenciamento Costeiro representa a linha mestra para as ações nos três níveis de governo. A exploração de recursos minerais nessa região é uma atividade antiga, relativamente de pouca expressão no contexto estadual, mas de grande significado social, econômico e cultural em nível regional, sustentando a demanda de vários municípios da região. Caracteriza-se principalmente pela exploração de areia e argila para uso na construção civil e para aterro, apresentando ainda potencialidade alta para exploração de turfa e minerais pesados. Com o objetivo de contribuir para a solução dos conflitos gerados por um modelo de exploração mineral ainda inconsistente com as demandas atuais de conservação e desenvolvimento, realizou-se uma análise ambiental integrada da área dos entornos do estuário da Laguna dos Patos, compreendendo os municípios de Pelotas, Rio Grande e São José do Norte. A análise considerou os marcos legais e institucionais, as características diferenciadas do meio físico-natural, os processos econômicos, sociais e culturais, as características da atividade de mineração na região e suas repercussões e interações no sistema ambiental como um todo. As informações disponíveis permitiram a geração de um banco de dados no Sistema de Informações Geográficas IDRISI 32®, na escala 1: 100.000, o qual forneceu a base para a análise interpretativa. Utilizando técnicas de geoprocessamento obteve-se uma síntese dos diagnósticos realizados através da definição, mapeamento e descrição de 19 unidades de planejamento, denominadas unidades geoambientais, posteriormente detalhadas em 108 unidades físico-naturais. A síntese de uma grande quantidade de dados, espacializada na forma de um mapa digital, auxiliou a definição dos critérios para elaboração de um mapa de vulnerabilidade ambiental relativa para a região. Este, aliado ao plano de informação que contém todas as áreas com restrição legal de uso, possibilitou o mapeamento das áreas mais críticas para gestão ambiental. Adicionalmente, considerando a potencialidade de recursos minerais para uso na construção civil e para aterro, os critérios que determinam a maior ou menor atratividade econômica para a sua exploração e as áreas mais críticas em termos de gestão ambiental, elaborou-se um mapa prescritivo que indica as áreas que devem ser consideradas prioritárias para um gerenciamento preventivo. Finalmente, a análise ambiental integrada permitiu a elaboração de um modelo de um plano de gestão para o setor, onde é apresentada uma estrutura seqüencial e ordenada do plano, exemplificada, em cada passo, com as informações disponíveis.

Análise da vulnerabilidade de Natal/RN frente às mudanças climáticas

The interaction between land and water, resulting from dynamic agents, such as wind, waves and tides, characterizes the coastal zone as a dynamic environment that is constantly disturbed and that may alter the balance of natural and man-made environment. Such modifications may be intensified when considering the climate change. This environment is highly attractive for the development of economic activities and urbanization, current scenario of the city of Natal. Weighing the economic importance for the state and the physical environment in which the capital of Rio Grande do Norte is inserted, this study aims to identify and analyze vulnerabilities and impacts caused by the rising sea level in the municipality. To that end, we defined a coastline, delimited areas susceptible to flooding and presented some flood scenarios. This way we could identify and analyze the impacts of each flood scenario in its respective section. Finally, it appears that the coastal zone in which Natal is inserted is a fragile area that requires actions aimed at mitigating vulnerabilities and facing the problem that caused the rise in the mean sea level (MSL), and mitigating the presented vulnerability framework; it is necessary to implement actions that effectively contribute to the protection and adaptation of the most fragile areas

Educomunicação: uma estratégia para promover o ambiente em uma área de proteção ambiental costeira

This study aimed to evaluate the potential of two public schools in Educommunication related to Environmental Protection Area Jenipabu (APAJ) located in Rio Grande do Norte / Brazil, based on perceptions of educommunicatives practices on the environment as well as perform an action included in the school APAJ. In the first phase of the research were three separate questionnaires designed to identify the actions, practices and experiences of three sets of audiences: teachers, students and parents from both schools. In the second phase, activities were carried out as educomunicatives class actions involving ride, maps of environmental design and construction of a mural on the school newspaper APAJ. We opted for the participant, making the observation in a previous visit to knowledge of the schools, where they made the first contacts with the administrative team, teachers and students, and then the application of semi-structured questionnaire to teachers, students and parents of the 4th and 5 years of elementary school the morning hours. The results showed the detachment of these actors in the knowledge, participation and involvement with APAJ, caused by the absence of actions and actions involving teaching practices educomunicatives students to interact with the environment, taking as its starting point the living space.

Dinâmica Costeira dos Campos petrolíferos Macau/Serra, litoral setentrional do Estado do Rio Grande do Norte

This thesis describes the general behavior of the northern shore of the State of Rio Grande do Norte relating beach profile morphology with hydrodynamic and sedimentological parameters. The Macau and Serra Oil Field are inserted on this area and are under accelerated coastal erosion. At these oil fields are installed oil wells from PETROBRAS, nowadays located directly in the shoreline, under constant attacks of coastal processes (e.g. waves, tides and currents), which promote an intense morphodynamic variability of this sandy coast. The area was monitored for 24 months in three different stations (P01, P02 and P03). The methodology applied involved current techniques of beach profiles, hydrodynamical processes, remote sensing and geophysics. A synthesis of results obtained through the use of different time scales (monthly, lunar cycle, seasonal, annual) from a coastal dynamics study is presented. The average wind direction corresponded to 77ºAz (NE). The steepness of the berm and of the shoreface, as well as coastal current direction, do not present major changes, with an average of 36º for the steepness of the berm, 15º for the shoreface and 15º for the coastal current direction. This data set allows us to infer that the months of larger coastal erosion were November/2000 and April/2001, because of the largest wave parameter during this time. The months of worse coastal erosion in this area are related with the increasing wavy energy. This in turn, seems to be related to seasonal climatic variations, with the wave energy and tide currents speed increasing during months of minor precipitations (June to January). The months of worse coastal erosion were September and November, when the largest wave parameters and speed currents are measured in the area. Since these months are included on the period of minor precipitations, we related the coastal erosion to seasonal climatic variations. The results obtained during these 24 months of monitoring confirms a situation of accentuated erosion, mainly in Profile 03 (Barra do Corta-Cachorro), where the wave height, period, and coastal current speed are always larger than the values found in Profile 02 (Macau5). Probably these values are more expressive in Profile 03, because it does not present any natural structure of protection against the wave impacts, as the barrier island located at Ponta do Tubarão, or the sand banks in front of Macau5. The transport of the sediments occurs from East to West, and the sand accumulation is more pronounced on Profile 03 intertidal zone, where there are embrionary dunes in dryer months. The tidal currents speed, on the other hand, is more accentuated in the Macau5 area (Profile 02). At Ponta do Tubarão, the tidal currents presented a preferential direction for NE, at times of flood, currents and for NW, at times of ebb current; at Barra do Corta-Cachorro the direction of the currents were predominantly for NW, independent of the tide phase, coinciding with the preferential direction of the longshore current. This currents inversion at Ponta do Tubarão is attributed to the presence of the Ponta do Tubarão island barrier and by the communication channel of the lagoon with the sea. The tide currents are better observed in protected areas, as in the Ponta do Tubarão, when they present inversion in their direction accordingly to the flood and ebb tide. In open areas, as in Barra do Corta-Cachorro, the tide currents are overprinted by the longshore currents. Sediment analysis does not show important modifications in grain size related to seasonality (dry- and rainy seasons). On the foreshore and backshore zones, the sediments vary from fine to medium sand, while in the shoreface they very from fine to very sands. The grains are mostly spheres, varying from sub rounded to sub angled. Quartz is the main component alongside Feldspat and heavy minerals as accessory components. Biogenic content is also present and mainly represented by mollusks fragments. The calculated sediment transport show values around 100 m3/day. The morphodynamic studies indicated that this is a reflexive area from October to April, and intermediate from May to September. The Relative Tide Range-RTR for this area is 4 < RTR < 15, and so classified in the mixed wave-tide group. Having this exposed we can affirm that the more active natural factors in this area are the currents, followed by the tides and the winds. The anthropic factors are exclusively local and punctual (Macau and Serra Oil Field). Taking in account the economic importance of the area, as well as the intensity of coastal processes acting on this shore, it is important a continuity of the monthly environmental monitoring looking for variations on longer-period cycles. These data have been stored on the geo-referenced database of the projects MARPETRO and PETRORISCO (REDE 05), aiming to model the coastal and sea environment, susceptible to oil spills and their derivatives

Análise de risco à erosão costeira na região de Tibau do Sul/RN através de mapeamento geoambiental e análise morfodinâmica

The research area is located on the county of Tibau do Sul, in the east coast of Rio Grande do Norte State, about 80km south of the capital Natal. The tourism represents the main income activity and Pipa beach is the most visited beach in the city, annually receives a large influx of domestic and foreign tourists. Some recent studies have reported the occurrence of coastal erosion in this littoral, being the main objective of the research, analyze the existing coastal erosion, through two methodologies, the geoenvironmental mapping and beach morphodynamics. The geoenvironmental mapping was done from oblique aerial photographs and field visits, which sought to carry out first the geomorphological mapping, with the purpose of analyzing features that suggest susceptible areas to erosion, as areas without protection of natural dunes, marine terraces, or sandstones (beach-rocks and ferruginous sandstones), areas with the presence of gullies and stretches where the sea-cliffs were in direct contact with the action of the sea, representing the beginning of the beach profile. In the morphodynamic study sought to carry out the survey of the physical and morphological characteristics, the analysis of sediment grain of the beaches and finally the analysis of the morphodynamic parameters to generate a table of risk to erosion by sector of the beach. The morphodynamic parameters were defined by the methodology proposed by Short (2006), in which considers different patterns of dynamism on beaches with characteristics favorable and unfavorable to erosive profiles. The maps indicated different levels of risk to the segments of the beaches analyzed, suggesting risk to erosion low and low to moderate only in areas north and northwest of the beaches of Madeiro and Curral, and levels of moderate and high risk sectors in the south and southeast of these beaches . The beach of Pipa showed moderate levels of risk and moderate to high at the ends and high risk to erosion in the central portion. The study of the coastal environment, its morphological evolution, and areas with problems of erosion, are of fundamental importance to assist coastal management policies, giving grants for planning activities undertaken in these regions

Estudo evolutivo das condições ambientais da região costeira do município de Guamaré - RN

The work concerns on the evolutionary study of the environmental conditions of the coastal area of Guamaré-RN, where was investigated the geo-environmental transformation occourred in this region, whose primordial purpose was to diagnose the changes verified in the temporary space of five decades (1950 to 2001). With the objective of evaluanting the action of the active coastal processes (currents, waves, tides and winds), in order to understand the generating mechanisms of the erosion/sedimentation, evidenced by constant morphologic changes. The adopted methodological procedure consisted of a succession of stages, involving bibliographical and cartographic study, aereal photographs study, digital treatment of images, field work (sample collection, beaches profiles, characterization of the beach environment and morfodynamics), mapping correction and laboratory analyses (granulometry). The evolutionary study of the morphologic features indicated significant variations in the studied period, mainly, in the dunes, sea terraces, variation of the shore line and tidal flat, evidencing the largest transformations in the temporary space between 1988 and 2001. The analyses of the beach profiles showed a sedimentation tendency in the area of the profiles P1, P2 and P3, however in the monitored pediod, it was observed in the referred profiles, erosive and depositionals intervals evidencing a need of more effective monitoring. The results of the granulometric analyses indicate a predominance of mean to coarse sand in the backshore and estirancy area, as in the shoreface, the analyses indicated medium to fine sand. The morfodynamic state, showed that beach of Minhoto is intermediate state, with alternancy to reflective. The areas of larger vulnerability and sensibility are the tidal flat, shore line, barrier island and mobile dunes, that actually is suffering great environmental impact with expansion of the carcinoculture, urban presence and natural impacts (erosion of the shoreline)

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

A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais

The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed parallel to the coast, combined with coast engineering interventions. High energy hydrodynamic process are responsible for the morphological instability of the coast. The study was based on remote sensing data obtained between 1954 and 2007 which consist in orbital images from Landsat, CBERS and Ikonos satellites and aerial photos. With all data integrated on GIS environment it was possible to update thematic maps of geology, geomorphology, vegetation, soil and landuse and development of multitemporal maps pointing areas with erosion and depositions of sediments, defining the critical erosion process on this region. The bigger morphological changes are related to changes on wind patterns during the year, terrestrial and sea breezes during the day, with spits and barrier island migration, opening and closing of channels like the one parallel to the coast on the area of Serra and Macau oil fields. These factors combined with the significant reduction on sediment budgets due to the loss of natural spaces to sediment reworking contribute to the low resilience which tends to be growing on the area of Serra and Macau oil fields. In front of such scenery a detailed monitoring was done in order to find technological possibilities for coastal restoration. A pilot area was defined to start the project of mangrove restore together with beach nourishment in order to minimize the effect of the erosion caused by the channel parallel to the coast, contributing to stabilize the northeast channel as the main one. It s expected that such methodology will aid the coastal environments restoration and the balance between industrial activities and coastal erosion
