Compreender os processos evolutivos que ocorreram para a conformação atual do ambiente costeiro é de suma importância para estudos relacionados ao planejamento e a gestão do litoral. O presente trabalho tem como objetivo caracterizar a barreira costeira holocênica do setor sul de Jaguaruna-SC, do ponto de vista geológico, geomorfológico e evolutivo, através de dados de superfície e de subsuperfície, a fim de subsidiar a gestão costeira da região. O estudo foi realizado com base na interpretação de fotografias aéreas e na análise de dados geofísicos de GPR. Em superfície foram identificados quatro depósitos sedimentares compondo a barreira costeira: Depósito Eólico, Depósito Marinho Praial, Depósito Lagunar Praial e Depósito Paludial. Do ponto de vista geomorfológico, esses depósitos se apresentam na forma de dunas, praia, planície de cordões litorâneos e banhados, respectivamente. Além destes, cristas de precipitação e paleocanais se destacam na morfologia da barreira. Quanto às informações de subsuperfície, a principal observação está relacionada à influência do rio Urussanga sobre o ambiente marinho e praial durante a evolução da barreira. A presença de paleocanais em subsuperfície, juntamente com outras informações identificadas em superfície, permitiram caracterizar o comportamento evolutivo da barreira como regressiva. As seções de GPR possibilitaram identificar os paleocanais devido à presença de uma superfície erosiva em forma côncava, com alta amplitude e continuidade lateral. Acima dessa superfície ocorre o preenchimento dos canais em fases distintas. Estas informações de caráter geológico e geomorfológico têm implicações importantes para o planejamento e gestão territorial. O litoral sul de Jaguaruna é uma das poucas áreas costeiras do município que se encontra em estágio inicial de ocupação. No entanto, possui muitas restrições à ocupação que devem ser consideradas nesta urbanização. / Understanding the evolutionary processes that occurred for the current conformation of the coastal environment is very important for studies related to the planning and management of the coast. This study aims to characterize the Holocene coastal barrier southern sector of Jaguaruna-SC, geological, geomorphological and evolutionary point of view, through surface and subsurface data in order to support the coastal management in the region. The study was based on interpretation of aerial photographs and geophysical analysis of GPR data. In Surface, were identified four sedimentary deposits composing the coastal barrier: Eolic deposit, Beach-Marine deposit, Beach-Lagoonal deposit and Paludal deposit. The geomorphological point of view, these deposits are in the form of dunes, strandplain and wetlands, respectively. Beside these, precipitation ridges and paleochannels stands out in the morphology of the barrier. About the subsurface information, the main observation is related to the influence of the Urussanga river on the marine and beach environment during the barrier evolution. The presence of paleochannels in subsurface, along with other information identified in surface, allowed to characterize the evolutionary behavior of the barrier as regressive. The GPR sections enable to identify the paleochannels due to the presence of concave erosive surface with high amplitude and lateral continuity. Above these surface occurs channels filling in different phases. These geological and geomorphological information has important implications for the planning and territorial management. The southern coast of Jaguaruna is one of the few coastal areas of the municipality which is found in early stages of occupation. However, it has many restrictions on the occupation that must to be considered in this urbanization.

A zona costeira no Brasil tem mostrado progressiva concentração e diversificação das atividades humanas e já demonstra comprometimento dos recursos naturais e ecossistemas. Localizado no Sudeste do estado de Santa Catarina, o município de Jaguaruna possui área de 328,347 km² e 37 km de orla. A orla do município, assim como nos níveis regional, nacional ou global é o resultado da interação do continente com o mar. Da grande variedade de usos que nela se aplicam, torna mais complexa sua análise e planejamento. Nos seus subsistemas (meio físico natural, socioeconômico, e político jurídico administrativo) possuem suas complexidades e seus conflitos. Seja na degradação ambiental, nos conflitos de usos ou na ilegalidade de alguns empreendimentos, a gestão e planejamento destas problemáticas é uma meta a ser alcançada. Para subsidiar este objetivo, esta dissertação aprimora o método de valoração de conflitos da orla, a Matriz de Interações Costeiras, observando e analisando as interações entre usos e estruturas na orla do município. Juntamente com a aplicação da Matriz de Interações Costeiras, este trabalho desenvolve uma caracterização do meio físico natural e socioeconômico proporcionando uma visão de espaço geográfico que auxilia na compreensão e comparação dos resultados obtidos na Matriz. Nesta caracterização foi concluído que o espaço geográfico de Jaguaruna possui suas sensibilidades ambientais e praias de grande valor cênico, que sua economia, baseada no setor de serviços, ainda pode ser mais diversificada buscando atividades turísticas como matriz. Ainda, na aplicação da Matriz de Interações Costeiras, observou-se uma insatisfação da população quanto à gestão do território urbano, revelando nos conflitos de uso a ausência de planejamento. / The coastal zone in Brazil has shown a progressive concentration and diversification of human activities and has demonstrated commitment of natural resources and ecosystems. Located in the southeastern state of Santa Catarina, the city has an area of Jaguaruna 328.347 km² and 37 km of coastline. The edge of the city, as well as in regional, national or global levels is the result of the continent's interaction with the sea. The wide variety of uses to which it applies, becomes more complex analysis and planning. In its subsystems (the natural physical, socio-economic, administrative and legal political) have their complexities and conflicts. Be environmental degradation, conflicts of uses or illegality of some projects, the management and planning of these issues is a goal to be achieved. To support this goal, this work enhances the valuation method of the waterfront conflicts, Matrix Coastal Interactions, observing and analyzing the interactions between uses and structures in the city's waterfront. Along with the application of the Coastal Interactions Matrix, this paper develops a characterization of the natural and socioeconomic physical environment providing a view of geographic space that helps to understand and compare the results obtained in the Matrix. This characterization was concluded that the geographic space Jaguaruna has its environmental sensitivities and great scenic value of beaches, its economy based on the services sector, may still be seeking more diverse tourist activities as matrix. Still, the implementation of Coastal Interactions Matrix, there was a dissatisfaction of the population as the management of urban territory, revealing the use conflicts the lack of planning.

O Balneário Cassino, Rio Grande - RS possui intensa atividade turística, com uma população fixa estimada em 30.000 moradores (2010), chegando a abrigar nos meses de verão, aproximadamente 150.000 visitantes. Nesses períodos, a demanda de serviços como habitações, comércios e infraestruturas é aumentada drasticamente. E a carência destes serviços acarreta consequências graves para o meio ambiente e para a economia. Buscando minimizar os possíveis impactos negativos e explorar melhor as características do balneário é que este trabalho tem como objetivo propor subsídios para a construção de um plano de ações para o desenvolvimento do sistema turístico no Balneário Cassino. Para tanto, foi necessária a aplicação de questionários aos principais atores envolvidos com esta atividade. As questões trabalhadas tinham como base duas ferramentas metodológicas, o Protocolo de Avaliação Turística (Inskeep, 1991), e a Análise SWOT. Como resultado principal, foi identificado que, hoje, a opinião dos principais envolvidos com o turismo é de que o balneário não está preparado para esta atividade. Sendo apontadas como maiores empecilhos questões ligadas à infraestrutura e a especulação imobiliária. Como pontos positivos, foram destacadas a beleza cênica e a geração de empregos. Por fim, com base nas informações dos entrevistados, foram apontadas as ações de planejamento para subsidiar melhorias ao setor turístico. / Tourism has emerged as the activity with the highest growth rate in the last decade. At the Cassino Beach, Rio Grande – RS has an intense tourist activity, with a permanent population estimated at 30,000 residents in 2010, and the village comes to house during the summer months approximately 150,000 visitors. In these periods, the demand for services such as housing, shops and infrastructure is drastically increased. The lack of these services entails serious consequences for the environment and the economy. Seeking to minimize possible negative impacts and exploit the best features of the beach this paper aims to propose subsidies for the construction of an action plan for the development of the tourism system at the Cassino Beach. Therefore, it was necessary to apply questionnaires to the main actors involved in this activity. The questions were worked out based on two methodological tools, the Evaluation Touristic Protocol (Inskeep, 1991) and SWOT Analysis. As a main result, it was identified that, today, the views of the key stakeholders in tourism is that the beach is not ready for this activity. Being identified as major obstacles infrastructure issues and real estate speculation. The positive highlight the scenic beauty and jobs creation. Finally, based on the respondents information’s, also were identified planning actions to support improvements to the tourism sector.

Há na zona costeira brasileira uma significativa ação antrópica datada de muito tempo, que foi acentuada após o início do processo de colonização no litoral do país. Dentro deste contexto, a questão dos impactos antrópicos nesse sistema natural torna-se de grande importância. Em função da fragilidade ambiental e a pressão do uso da terra observadas na região do Litoral Norte do estado de São Paulo, o presente trabalho realizou um estudo de zoneamento geoambiental para os municípios de Caraguatatuba, Ilhabela, São Sebastião e Ubatuba, em escala 1:100000, por meio da Geoecologia das Paisagens em uma metodologia proposta por Rodriguez, Silva e Cavalcanti (2007), que buscou analisar os aspectos naturais e antrópicos, definindo unidades geoambientais e o estado ambiental das diferentes regiões na área de estudo, para que os resultados pudessem servir como auxílio para o Gerenciamento Costeiro / Abstract: The coastal environment is constantly changing, and this is a dynamic and fragil environment, forming areas of high vulnerability due to natural processes that predominate, therefore, a naturally unstable area. There in the Brazilian coastal zone a significant anthropic activity dated since a long time, which was accentuated after the beginning of the colonization process on the coast. Within this context, the issue of human impacts in the natural system becomes of great importance. According to the environmental fragility and the pressure of land use observed in the North Coast of São Paulo, this research conducted a study of geoenvironmental zoning for the municipalities Caraguatatuba, Ilhabela, São Sebastião and Ubatuba, in a scale 1:100,000 through the Geoecology of Landscapes on a methodology proposed by Rodriguez, Silva and Cavalcanti (2007), which seeks to analyze the natural and human aspects, defining geoenvironmental units and environmental status of different regions in the study area, so that the results could serve as an aid for Coastal Management / Mestrado / Análise Ambiental e Dinâmica Territorial / Mestra em Geografia

Depuis les années 1980, les dispositifs participatifs se sont multipliés de par le monde, sans pour autant qu’ils n’aient permis de démocratiser la vie politique. Alors que l’adoption de tels dispositifs est souvent pensée comme un impératif, en particulier pour les pays en développement et dans le domaine de l’environnement, cette thèse s’applique à expliquer la construction de la participation environnementale en Afrique du Sud, à l’aide d’une démarche visant l’identification des acteurs impliqués, l’analyse de leurs motivations et de la manière dont ils l’influencent. Notre cadre d’analyse propose d’étudier le comportement de catégories d’acteurs au travers de quatre dimensions : la compétition entre acteurs politiques ; le poids des structures administratives ; le profil des prestataires professionnalisés ; les combats des acteurs sociaux. Notre enquête s’appuie sur des entretiens semi-directifs, l’observation de réunions, la littérature grise ainsi que la collecte d’archives. Au terme de notre thèse, nous constatons un faible intérêt des acteurs politiques pour les dispositifs participatifs environnementaux en Afrique du Sud. Cela engendre un manque d’incitation à la prise en compte de la voix du public par les structures administratives, conduisant généralement à une organisation a minima de la participation du public par les consultants, qui ne permet qu’à une minorité de la population sud-africaine de s’exprimer. Des fonctionnaires qui ne sont pas soutenus par les structures administratives avec lesquelles ils devraient collaborer cherchent toutefois à les contourner en s’appuyant sur le public pour mettre en œuvre leur mandat de préservation de l’environnement. Afin de trouver une place sur le marché sud-africain de la participation dominé par des consultants environnementaux, des consultants indépendants choisissent également de se spécialiser dans la participation publique et de favoriser l’organisation de dispositifs participatifs adaptés aux contextes locaux. / Since the 1980s, participatory processes have proliferated all over the world, without having enabled for a democratization of political systems. While the adoption of such processes is often thought has an imperative, in particular for developing countries and in the environmental field, this thesis seeks to explain the construction of environmental participation in South Africa, using an approach aiming at identifying the actors involved, analyzing their motivations and the way in which they influence it. Our analytical framework offers to study the behavior of groups of actors through four dimensions: the competition between political actors; the weight of administrative structures; the profile of professionalized service providers; the struggles of social actors. Our study relies on semi-structured interviews, meetings’ observations, grey literature and the collect of records. At the end of our thesis, we notice little interest from political actors for environmental participatory processes in South Africa. This causes a lack of incentive for administrative structures to take the public voice into account, usually leading to a low-cost organization by consultants, which does only allow for a monitory of the South African population to express itself. Civil servants who do not have the support of administrative structures with which they should collaborate try nonetheless to circumvent them by seeking public support so that they can implement their mandate for environmental preservation. In order to make their way into the South African participation market dominated by environmental consultants, independent consultants also choose to specialize themselves into the public participation field and to favor the organization of participatory processes adapted to the local context.

Effective coastal planning is inclusive and incorporates the variety of user needs, values, and interests associated with coastal environments. This requires understanding how people relate to coastal environments as ‘places’, imbued with values and meanings, and accordingly, tools that can capture place and connect with people’s ‘sense of place’ have the potential for supporting effective coastal management strategies. Realistic, immersive geographical visualizations, i.e., geovisualizations, theoretically hold potential to serve such a role in coastal planning. However, significant research gaps exist around this application context. Firstly, place theory and geovisualizations are rarely explicitly linked in the same studies, leaving questions around the (potential) relationship between these tools and sense of place. Secondly, geovisualization work has focused on terrestrial environments, and research on how to realistically model coastal places is currently in its infancy. This dissertation aims to address these gaps by pursuing two research objectives. The first objective is to explore the ‘human component’ of geovisualizations, referring to how these tools operate within the social and cultural dimensions germane to environmental management plans and processes. In accordance with the discussion above, this exploration is framed through place theories and concepts, and regards realistic geovisualizations as ‘place-based’ tools. The second objective concerns the coastal context, and it involves elucidating the considerations around developing and using terrestrial-to-marine geovisualizations as tools for inclusive coastal planning and management. The dissertation is composed of five manuscripts, which have been prepared as standalone articles for submission to academic journals. Each manuscript details a study designed to support an aspect of the research objectives, respectively serving (1) to develop a theory of geovisualizations as place-based tools, (2) to explore the theory in the coastal context, (3) to examine the relationship between sense of place and one’s mental visualization of place, (4) to develop a coastal geovisualization under place-based considerations and examine its capacity for connecting to sense of place, and (5) to assess the geovisualization’s potential as a tool for inclusive coastal planning efforts. The first and second study consist of literature review work. The third study involves a survey administered to residents of the Capital Regional District, which collected data for examining a potential relationship between the way people visualize coastal places and how they value and relate to these places. The fourth and fifth study involve developing a coastal geovisualization of Sidney Spit, and then employing focus groups to examine its ability for connecting with people’s sense of place (i.e., fourth study) and utility as a tool for inclusive planning (i.e., fifth study). Outcomes from the first study include a theory on how geovisualizations can function as place-based tools, and this was developed by integrating place concepts with ideas and conceptual models from human-media interaction and sense of presence research. The second study produced insight on how values and interests of different coastal user groups can influence understandings and perceptions of coastal places, and it used this insight to develop recommendations for coastal geovisualizations - full navigability, dynamic elements, and flexibility (i.e., allowing for continual modification and scenario building). The third study produced empirical evidence that place-based values and interests (i.e., framed through sense of place and concerns for place) can influence one’s mental visualization of place in terms of the types of elements people include and perspectives they take in said visualization. The fourth study demonstrated that the presence of certain elements in coastal geovisualizations (such as people, dogs, birds, marine life, vegetation, and boats) can contribute to realism and sense of place; however, simultaneously, deficiencies in numbers and varieties of these elements can detract from realism and sense of place. In addition, the fourth study found that the incorporation of soundscape and viewshed elements is significant for the tool’s ability to connect with sense of place. The fifth study demonstrated the geovisualization’s usefulness for assessing certain qualities of management scenarios, such as aesthetics and functionality of fencing around a restoration area and potential viewshed impacts associated with locations of moored boats. The study also found that incorporating navigability into the geovisualization proved to be valuable for enhancing understandings around scenarios that hold implications for the marine environment because it allowed users to cross the land-sea interface and experience underwater places. / Graduate

Egmont Key, located at the mouth of Tampa Bay, is part of a dynamic system with many interrelated natural and anthropogenic factors influencing its morphodynamics. This study started in August 2012. During the 3-year period until August 2015, 28 beach profile transects were established and surveyed 10 times. Seventeen historical aerial images from 1942 to 2013 were geo-rectified and analyzed. Three hundred and fourteen sediment samples were procured from the navigation channel dredge area and the beach nourishment area and analyzed for grain size. A numerical wave model was established to simulate the nearshore wave field. The overall goals of this study are to understand the complex morphodynamics of Egmont Key and to evaluate the shore-protection efforts. The overall area of the Egmont Key has reduced 52% from 2.1 km2 in 1942 to 1.o km2 in 2002. The area loss was mostly caused by beach erosion along the Gulf-facing beach. The island-area reduction from 1942 to 2002 was largely linear. Two periods of accelerated area loss from 1978-1984 and 1999-2002 can be related to dredging of the Egmont Channel and the disposal of dredged materials along the channel. Concerning the relatively high mud content in the borrow area for the 2014 nourishment, a large amount of the fine sediment was lost at a temporal scale of hours to days during the dredging and beach nourishment construction processes. Some of the mud was deposited outside the surf zone at water depths of 2 m or greater. This mud became eroded naturally by energetic conditions at a temporal scale of months. Beach erosion and accretion along the Gulf-facing beach can be related qualitatively to tidal flow patterns. Numerical wave modeling shows that the transverse bars offshore Egmont Key have a moderate influence on the wave field, leading to slightly different wave heights along the shoreline. However, there is no clear relationship between the nearshore wave conditions and the erosion/accretion patterns. The severe shoreline erosion has exposed various fort structures at the shoreline and in the nearshore zone. These structures function as detached breakwaters or groins and have localized influence on the beach state.

To achieve true sustainability, planners must balance the interests of environmental protection, economic development, and social equity. In a critically changing, complex ecosystem such as Louisiana’s coast, challenges to achieve the perfect equilibrium are further compounded. Following the logic of emerging adaptive co-management literature, the planning framework for Louisiana’s Coastal Master Plan could be transformed into a more collaborative, democratic process. Adaptive co-management is a regime which provides power to local citizens, often in possession of invaluable traditional ecological knowledge. In general, it focuses on constant learning and collaboration. Through power-sharing and participatory action, we embrace science, but step back from technocracy. We utilize local knowledge, and combine it with expertise.
