Tourism is acquiring the attention worldwide especially in the developing countries (Akpabio et al. 2006). In the case of coastal areas, tourism is more sensitive to environmental degradation compared to other economic activities because the environment is its primary resource. With the help of efficient planning and proper management of natural resources, tourism can significantly contribute to environmental conservation and to achieve environmental sustainability in coastal areas (Orhon et al. 2011). The main purposes of this study are to explore the tourism development trend in coastal areas of Cox’s Bazar, to analyse existing environmental conditions of Cox’s Bazar coastal area, to examine the importance of environmental sustainability at coastal region. More positively, the study shows environmental sustainability can be achieved through more eco-friendly planning of installations in tourism hubs like Cox’s Bazar. The main methods of conducting this study were desktop research; data collection through questionnaire survey and expert interview; data input in SPSS, processing and analysis; evaluation of policies, strategies and institutional framework. To formulate study goal and objectives, a comprehensive literature review has been conducted to understand about tourism, tourism development, sustainability, sustainable development by reviewing relevant reports, journals, and international cases which has helped to develop the conceptual framework of the study. After extensive literature review and formulation of goal and objectives, the conceptual framework of the study data collection instruments such as questionnaire has been prepared to collect data from the field. The study is largely based on the primary data collected through field visit, interviews to the experts on tourism and environment, and questionnaire survey at the study area, Cox’s Bazar. In this study, the statistical data on the study area has been collected from Bangladesh Bureau of Statistics (BBS). Apart from this, information has also been collected from various sources e.g. journals, projects, periodicals, and the daily newspapers, archives of both home and abroad. From the analysis, it found that Cox’s Bazar sea beach is a good place for tourism development, and it is also found that the level of tourism is improving gradually. Tourism in Cox’s Bazar mainly depends on natural beauty and environment of the coastal area. Tourism is producing long term negative effects on the coastal environment. If the environmental systems degrade tourism will not sustain any more. However, tourism can provide incentive for the conservation and restoration of the natural environment. Nearly half of the respondents stated that because of tourism, natural environment is in better condition in Cox’s Bazar and tourism provides incentive for the conservation and restoration of the natural environment. The analysis also identifies that policies and strategies play a big role to the conservation of natural environment and resources, and the implementation of principles of sustainable development. Government of Bangladesh (GoB) has been formulated some policies and strategies related to tourism development, sustainable development and coastal zone management, but most of the policies and strategies are not implemented properly because of institutional conflicts. In the light of the data analysis, discussion and findings, some recommendations are suggested here to help and guide future decisions regarding tourism development, conservation of the environment, sustainable development and sustainability at coastal areas in Bangladesh. / published_or_final_version / Urban Planning and Design / Master / Master of Science in Urban Planning

L'inondation est l'un des principaux risques d'origine naturelle dans le monde. Face à ce risque amplifié par le changement climatique, penser les stratégies de gestion est devenu fondamental, particulièrement sur les côtes basses. La perception du risque, notion complexe renvoyant à des aspects cognitifs, sociaux, économiques et environnementaux, constitue un réel apport pour révéler les points de vulnérabilité des populations. Cette thèse porte sur l'analyse de la perception du risque d'inondation de la population de la communauté urbaine de Dunkerque. Sur ce territoire, situé sur une côte basse densément peuplée, urbanisée et historiquement concernée par l'inondation, une large enquête de perception a été menée auprès des habitants et des acteurs de la gestion du risque. Le but étant de mesurer leur perception du risque d'inondation et de mettre en évidence les différents facteurs qui l'influencent. L'enquête a été menée selon une méthodologie se situant à la croisée de plusieurs disciplines (géographie, sociologie, psychosociologie et économie). Les résultats mettent en évidence, dans la population : (1) une perception dissonante du risque d'inondation et une faible préoccupation à son sujet ; (2) des représentations spatiales du risque très différentes des officielles ; (3) l'influence de la perception du risque sur le consentement à payer pour s'en prémunir. Cette thèse fournit un apport pour les sciences cindyniques et la géographie des risques. Elle propose des adaptations pour diminuer la vulnérabilité de ces habitants face aux inondations. / Flooding is one of the world's main natural hazards. In view of this risk, being amplified by climate change, management has become crucial, especially in low-lying coastal areas. Risk perception, as a complex notion referring to cognitive, social, economic and environmental aspects, is a real contribution to reveal the vulnerability points of populations. This PhD thesis adresses the analysis of the population's perception of the flood risk within the "Communauté Urbaine de Dunkerque". In this territory, located on a densely populated, urbanized and historically flood-affected low-lying coastal area, a large perception survey was carried out among inhabitants and risk management stakeholders. Its aim was to measure their flood risk perception and to bring to light various factors that influence it. The survey was conducted according to a methodology at the crossroads of several disciplines (geography, sociology, psychosociology and economics). The results highlight : (1) a discordant perception of this risk and a low concern ; (2) spatial risk representations very different from official ones ; (3) the influence of risk perception on willingness to pay to prevent themselves from risk. This thesis provides input to cindynics sciences and risk geography. It suggests adjustments to reduce these inhabitant's vulnerability to flood risk.

In an era of rapidly growing maritime trade, national and international efforts to prevent marine environmental disasters have taken various dimensions, including vessel safety mandates, traffic control measures and increased state inspections and control of ships. The advent of large modern tankers has generated new marine environmental risks. The customary right of access to a place of refuge for vessels in distress is becoming a complex issue of increasingly conflicting values reflecting humanitarian response and environmental conservation. A national ‘Places of Refuge’ policy is an essential component of Canada’s oceans management strategy. A cohesive and robust structure for conflict resolution will help assure the continued progress and development of ocean-based industries and minimize threats to Canada’s oceans and marine environment. The input of ship and port management personnel in the development of a national strategy and risk assessment procedure is vital for credibility and acceptance. The Canadian and international experience of ships in need of assistance and the lessons learned dictate that developing a ‘Places of Refuge’ policy and risk assessment procedure is not only prudent but imperative if Canada is to continue to be a major player in the global marketplace. This dissertation outlines a risk assessment procedure to categorize Canadian ports as places of refuge. This categorization of ports based on defined risk levels allows for the optimum allocation of resources for upgrading the refuge suitability of ports. Twenty-one ports on the east coast are evaluated for their suitability as places of refuge, based on their risk category. The measures suggested in this thesis propose elements of a Canadian national policy and risk assessment procedure for places of refuge which are comprehensive, pragmatic and flexible within the country’s existing command and control infrastructure.

Les blocs supratidaux de tempête que l’on trouve au sommet des falaises vont à l’encontre du schéma classique qui décrit l’érosion des falaises. Généralement, le recul des escarpements rocheux se fait au rythme des écroulements gravitaires dont les éléments s’accumulent en pied de falaise, la mer intervenant surtout dans le déblaiement des matériaux accumulés à la base des versants. Dans le cadre de cette thèse, nous étudions les processus d’érosion qui se traduisent par l’accumulation de dépôts grossiers en sommet de falaise. Nous montrons qu’au cours des événements météo-océaniques extrêmes, les effets combinés d’un niveau d’eau à la côte particulièrement élevé et du déferlement de vagues de haute énergie peuvent se manifester localement par l’arrachement et le transport de blocs littoraux supratidaux. Leur masse peut dépasser plusieurs dizaines de tonnes, et leur remaniement peut se faire à plusieurs mètres au-dessus du niveau des hautes mers. De même, leur déplacement peut atteindre plusieurs dizaines à centaines de mètres à l’intérieur des terres. A l’heure où l’on s’interroge sur une possible intensification et/ou augmentation de la fréquence des événements météoocéaniques extrêmes, la dynamique morphosédimentaire de ces blocs littoraux apparait comme un indicateur géomorphologique pertinent pour l’évaluation de ces changements. Un suivi topo-morphologique, sédimentaire et hydrodynamique pluriannuel a été réalisé sur plusieurs sites bretons (Finistère) et islandais (presqu’île de Reykjanes). Les résultats de ce suivi ont montré des schémas de circulation hydro-sédimentaire bien distincts suivant le contexte morphodynamique. Si dans certains cas, les processus transversaux prédominent dans l’édification et le remaniement de ces accumulations, dans d’autres cas, la composante longitudinale contrôle une partie des transferts à la côte. Les processus d’arrachement et de transport de blocs sont concomitants, et peuvent se produire à plusieurs reprises au cours d’un même événement et/ou hiver, y compris pendant les tempêtes d’intensité modérée. L’étude rétrospective des conditions météo-océaniques favorables au déclenchement de ces processus sur les 70 dernières années montre une forte variabilité interannuelle, sans périodicité ni tendance particulière. Cette variabilité est commandée par la dynamique atmosphérique WEPA aux latitudes tempérées de la Bretagne, et par l’ONA aux latitudes sub-polaires de l’Islande. / Cliff-top storm deposits (CTSDs) corresponding to boulder accumulations are locally identified along the North–Atlantic coasts (Iceland, Scotland, Ireland, France), where they are defined as one of the most remarkable morphosedimentary storm signature. Their study aims to understand the effects of high energy storm waves on these specific rocky cliffed coasts facing deep–water and exposed to energetic wave–climates. Recent works demonstrated the role of high energy storm waves (instead of tsunami waves) in transporting and supplying in boulders these deposits. In the context of climate change, and the possible intensification and/or increase in frequency of extreme meteo-oceanic events, CTSDs appears as a potential geomorphological indicator for the monitoring of these changes on high-energy rocky coasts. This thesis propose an analysis of their morphosedimentary dynamics based on field observations realized at high (64°N) and medium (48°N) latitude of the Northeast Atlantic basin. In the present work, their morphosedimentary dynamics have been annually surveyed using low altitude aerial photographs. Results shows two different hydrosedimentary circulation patterns of CTSDs. The first one concerns inland boulder transport, corresponding the directions of the incident waves. This pattern confirms the contemporary edification of ridges. The second one concerns longshore or seaward boulder transport, describing a longitudinal drift of this sedimentary material.The processes of quarrying and transport of CTSDs are concomitant and can repeatedly occur during one single event and/or winter, including during regular storms. The retrospective analysis of sea weather forecast favorable to these processes during the last 70 years showed an infraannual frequency with no particular periodicity nor tendency.

Esta dissertação foi realizada junto ao Projeto Lagoas Costeiras 3, patrocinado pela Petrobras e desenvolvido por pesquisadores da Universidade de Caxias do Sul (UCS), entre 2014 e 2016. O estudo foi feito por meio de uma pesquisa exploratória de natureza qualitativa e teve como objetivo identificar, caracterizar e mapear as atividades do turismo de aventura no município de Osório-RS, dentro de uma perspectiva ambiental. Utilizou-se como técnicas de levantamento de dados visitas de reconhecimento à região, observação in loco com registro fotográfico e entrevista com ofertantes do segmento de aventura. As entrevistas foram aplicadas a nove operadoras especializadas em atividades de aventura, foram transcritas, tabuladas e analisadas para interpretação dos resultados. As visitas e observações in loco complementaram as informações obtidas pelas entrevistas. Em Osório, foram identificadas 12 modalidades do segmento (Kitesurf, Stand up paddle, Barco a Vela, Windsurf, Canoagem, Planador, Paraglider, Paramotor, Asa Delta, Mountain Bike, Caminhada em trilhas e Cavalgada). Entre os serviços oferecidos pelas operadoras, 65% são desenvolvidos na água, 20% no ar e 15% na terra. Chegou-se a uma estimativa de 4.060 atendimentos realizados por ano nas operações de aventura em Osório, em sua maioria, oriundos da grande Porto Alegre, Vale do Sinos e Serra Gaúcha. Dos nove entrevistados, oito relataram preocupar-se com a qualidade do ambiente onde realizam suas atividades, dos quais dois realizam ações para sensibilizar seus clientes sobre a conservação dos locais onde as atividades são desenvolvidas. Os resultados indicam a vocação do município para o turismo de aventura, devido sua diversidade de recursos naturais, lagoas, montanha e oceano, além, da presença marcante do vento, possibilitando a prática de 60% das modalidades identificadas. Uma característica marcante para o turismo em Osório é sua posição geográfica, localizada a cerca de 90 km da capital do estado, Porto Alegre, assim como possuir vias de acesso de qualidade o que facilita o deslocamento até o local. Osório possui características geográficas e paisagísticas que poderiam tornar o município um destino turístico de contato com a natureza, priorizando a qualidade de vida por meio do lazer somado ao esporte, saúde e aventura. / Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2017-02-17T16:10:27Z No. of bitstreams: 1 Dissertacao Lucas Fruet Gil.pdf: 3451987 bytes, checksum: 364b2a6151e0185c88a1e35de48a4939 (MD5) / Made available in DSpace on 2017-02-17T16:10:27Z (GMT).

The study was done by an exploratory research of qualitative nature. The objective was to identify, characterize and map the adventure tourism activities in the city of Osório-RS, within an environmental perspective. It was used as reconnaissance visits for data collection techniques to the region, on-site observation with photographic records and interviews with offerors segment of adventure. The interviews were applied of nine specialized operators in adventure activities, were transcribed, tabulated and analyzed to interpret the results. The visits and on-site observations complement the information from the interviews. In Osorio, were identified 12 activities (kitesurf, stand up paddle, boat sailing, windsurfing, canoeing, glider, paraglider, parafly, hang gliding, mountain biking, hiking trails and horseback riding). Among the services offered by operators, 65% are developed in water, 20% air and 15% on earth. It was estimated 4.060 attendances per year in adventure operations in Osório, coming from Porto Alegre, Vale dos Sinos and Serra Gaucha. Of the nine respondents, eight reported to worry about the quality of the environment where they perform their activities. Two operators take actions to educate their customers about the conservation of the sites where the activities are developed. The results indicate the city's potential for adventure tourism due to its diversity of natural resources, lakes, mountain and ocean. In addition, receiving enough wind allowing practice 60% of the identified activities. A striking feature for tourism in Osório is its geographical position, located about 90 km from the state capital, Porto Alegre. It also has quality access roads which facilitates transportation to the site. Osório has geographical and landscape features that could make the city a tourist destination. Promoting contact with nature, prioritizing the quality of life through leisure added to sport, health and adventure.

Os destinos localizados na região costeira, incluso os ambientes lacustres, são considerados os mais populares na atualidade no mundo. O Brasil destaca-se por sua extensa costa e por possuir atrativos relacionados ao sol e praia. No extremo sul do Brasil, no estado do Rio Grande do Sul, encontra-se uma região costeira considerada única no mundo. Essa região é privilegiada, pois além de possuir uma planície costeira com 37.000 km², ao longo de sua costa há aproximadamente 100 lagoas de água doce. A área de estudo abrange o município de Osório, localizado no Litoral Norte do estado, formado por um complexo lacustre com cerca de 23 lagoas. Além disso, essas lagoas estão inseridas em um mosaico de ecossistemas terrestres com uma alta diversidade, abrigando espécies ameaçadas de extinção. Assim, levando em conta a importância desses ambientes e as pressões antrópicas que o ameaçam, o presente estudo objetivou caracterizar o turismo nas lagoas de Osório, verificando a Disposição a Pagar-DAP dos moradores para sua preservação, utilizando-se do Método de Valoração Contingente. Os resultados do estudo demonstraram que essa teia de lagoas, além de seu valor ecológico, dispõe de um patrimônio histórico-cultural, ainda não explorados pelo turismo. Entre os entrevistados, mais de 70% estão dispostos a pagar pela preservação das lagoas costeiras. Estimou-se, por meio da DAP dos moradores, um valor total anual de R$ 931.491,86 para a preservação das lagoas costeiras. Acredita-se que esta pesquisa poderá contribuir para pensar as lagoas como ambientes plurais, fornecendo a comunidade e a gestão pública de Osório parâmetros para criação de um futuro fundo financeiro que vise a preservação desses ecossistemas. / Submitted by Ana Guimarães Pereira (agpereir@ucs.br) on 2017-02-17T17:20:11Z No. of bitstreams: 1 Dissertacao Rita Gabriela Araujo Carvalho.pdf: 4203296 bytes, checksum: 426e6a0566c92ee8e87b5c4850a64df9 (MD5) / Made available in DSpace on 2017-02-17T17:20:11Z (GMT).

The coastline of the city of Aracaju in Sergipe/Brazil, extending approximately for 24 km, is limited by the mouth of the Sergipe river in the north and the mouth of Vaza-Barris river in the south. In this work 7 beaches along Aracaju littoral were studied (Mosqueiro, Refúgio, Náufragos, Robalo, Aruana, Atalaia and Artistas), comprising 24 sampling points. The purpose of this dissertation is to outline the erosion and accretion processes of the Aracaju coastal area by using geoindicators of coastal erosion and accretion. The methodology included field campaigns over rainy (Aug/12) and dry (Feb/13) seasons, spatial geoindicators data, human settlement mapping and the development of coastal erosion vulnerability and risk maps using the ArcGIS 9.3.1 program. The Aracaju coastal area is characterized by beaches (ocean and estuary), surrounded by Quaternary sedimentary deposits predominantly from wind (foredune) and, by anthropogenic containment structures against coastal erosion. The erosion process is more effective on the beaches situated in contiguous areas to the mouths of Sergipe River ( Praia dos Artistas ), Vaza-Barris River ( Praia do Mosqueiro ) and in the middle of the beach arc ( Praia do Refúgio and Praia dos Náufragos , in the rainy season). The settlement level is high on the beaches of Praia da Atalaia , Praia dos Artistas , and non-existent on the beach of Praia do Mosqueiro . The coastal erosion vulnerability is high to moderately high on the beaches of Praia dos Artistas , Praia do Mosqueiro , Praia do Refúgio , Praia dos Náufragos , Praia da Aruana and Praia da Atalaia ; and moderately low to low in the other beaches. Depending on the coastal erosion vulnerability index and the human settlement level, the risk of coastal erosion is high on the beach of Praia dos Artistas and moderately high on the beaches of Praia do Refúgio , Praia dos Náufragos and Praia da Atalaia ; and moderately low to low in the other beaches. Although the coast of Aracaju pointed out a high risk just on the beach Praia dos Artistas , attention should be given to areas most vulnerable to erosion due to the intensification of human settlement over recent decades. The results of this study provide baseline information for environmental planning in the area analyzed, especially with regard to the human settlement near to the shoreline. / O litoral do município de Aracaju, Sergipe, com cerca de 24 km de extensão, é limitado a norte pela desembocadura do rio Sergipe e a sul pela desembocadura do rio Vaza-Barris. Neste trabalho foram estudadas 7 praias do litoral de Aracaju (Mosqueiro, Refúgio, Náufragos, Robalo, Aruana, Atalaia e Artistas), totalizando 24 pontos amostrais. O objetivo dessa dissertação de mestrado é caracterizar o processo de erosão e de acumulação do litoral do município de Aracaju através da utilização de geoindicadores de erosão e de acumulação costeira. A metodologia incluiu campanhas de campo no período chuvoso (agosto/2012) e no período seco (fevereiro/2013), espacialização dos dados de geoindicadores, e mapeamento da ocupação humana e elaboração dos mapas de vulnerabilidade e risco à erosão costeira no programa ArcGis 9.3.1. O litoral de Aracaju caracteriza-se por apresentar praias, oceânicas e de desembocadura, bordejadas por depósitos sedimentares quaternários, predominantemente de origem eólica (dunas frontais), e por estruturas antrópicas de contenção à erosão costeira. O processo erosivo é mais efetivo nas praias situadas nas áreas contíguas às desembocaduras dos rios Sergipe (Praia dos Artistas) e Vaza-Barris (Praias do Mosqueiro), e no meio do arco praial (Praias do Refúgio e dos Náufragos, no período chuvoso). O nível de ocupação é alto nas praias da Atalaia e dos Artistas, e inexistente nas praias do Mosqueiro. A vulnerabilidade à erosão costeira é alta a moderadamente alta nas praias dos Artistas, do Mosqueiro, do Refúgio, dos Náufragos, da Aruana e da Atalaia; e moderadamente baixa a baixa nas demais praias. Em função do grau de vulnerabilidade à erosão costeira e do nível de ocupação humana, o risco à erosão costeira é alto na praia dos Artistas e moderadamente alto nas praias do Refúgio, dos Náufragos e da Atalaia; e moderadamente baixo a baixo nas demais praias. Apesar do litoral de Aracaju apresentar risco elevado apenas na praia dos Artistas, atenção deve ser dada nas áreas mais vulneráveis à erosão em função da intensificação do processo de ocupação humana ocorrida nas últimas décadas. Os resultados deste estudo fornecem subsídios ao planejamento ambiental da área investigada, principalmente no que diz respeito à ocupação humana próxima à linha de costa.
