The coastal zone including coastal waters and littoral zone are influenced by the interactions between sea and land, and the resources of coastal areas have significant functions and values whatever the regards of nature ecology, industry development, transportation, tourism, national defense, and academic research. Following the population growth, economic advancement, and the change of industry, the land use of coastal zone is more diverse and complex. The incompatible between development and marine environment was happened sometimes. In order to solve the conflicts of coastal resources multiple use and mitigate the negative effects by human activities, integrated coastal zone management was become the most important way for sustainable using the sea. ¡§Integrated Coastal Zone Management (ICZM)¡¨ is a resource management system applying the process of integration, connection, and interaction, to analyze the complicated management problem at coastal areas. It is also a framework of principles and methodology for identification of important environmental priorities and allocation of scarce resources. It is an integrated management planning process emphasizing the comprehensive aspect to achieve the sustainable development of the coastal zone. Because the laws and regulations about land planning and coastal zone management is under legislation and the ¡§Coastal Zone Management Plan¡¨ of Kaohsiung County is not accomplished, the research attempts to understand the future development concept and direction about coastal areas in Kaohsiung County according to ¡§Kaohsiung County Comprehensive Development Plan¡¨. The research formulates some phenomena at present involving artificial construction causing coastal erosion, making land destroying the ecology, development project standing, development location overlapping, project contents competing each other, objective scale too large, disregard environmental sensitive areas, using a lot of hard structures, etc. Furthermore, we survey the planning and management of coastal zone through the aspects of integration among sectors, between the land and the water sides of the coastal zone, among levels of government, and among disciplines. Synthesizing the discussions of research, we can find the major problem of coastal zone management at Kaohsiung County is not lacking of planning project, instead of having too many but the implement result is not satisfactory. It is perceived that investigating and evaluating of the resource supply and the user demand at advance planning process was insufficient. Besides, it didn¡¦t have a comprehensive development plan which thinks about coastal environment from the first to be a basis of integration and coordination the various land use. Expecting the future coastal zone development and management, the responsible agency and project proponent can discard the departmental egoism, prior consider the integrated environment, proceed to communication, coordination, and integration continuously in search of a common consensus and vision. Only if that, the coastal zone development can be sustainable.

La question des énergies marines renouvelables dégage des problématiques juridiques complexes qui intéressent le droit tant dans sa dimension internationale, européenne que nationale. L’effervescence des initiatives publiques et privées en ce domaine implique une approche adaptée en vue d’améliorer et de développer les instruments juridiques nécessaires au développement durable des énergies de la mer. Cette approche suppose trois niveaux d’analyse. Au regard du droit international, celle-ci se caractérise par une finalité environnementale qui relève plus globalement de l’intérêt général. En ce sens, la conversion d’énergies marines n’engendre pas d’émission de gaz à effet de serre et son impact sur le milieu marin est généralement minime. Avec le concours des énergies de la mer, les États seront à même de respecter leurs engagements supranationaux, notamment en matière de changements climatiques. De surcroît, le droit de la mer offre une sécurité juridique dans l’utilisation de l’espace maritime en définissant non seulement les droits, mais les obligations des États côtiers. À l’échelle européenne, la sécurité juridique est liée à l’objectif d’une part d’au moins 20 % d’énergie produite à partir de sources renouvelables dans la consommation finale brute d’énergie de l’Union d’ici à 2020 et encouragée par l’initiative des États riverains des mers du Nord en faveur d’un réseau off-shore dans le contexte de l’émergence du marché européen des énergies renouvelables. Au plan national, l’analyse du droit interne met en lumière les meilleures pratiques relatives au développement des énergies marines renouvelables en termes de promotion des investissements et de gestion durable des mers et des océans. / The issue of marine renewable energies raises complex legal problems which interest the Law in its International, European and Domestic dimension. The effervescence of public and private initiatives on the matter requires a tailored approach to improve and develop legal instruments to support development of ocean energies. This approach elicits three levels of analysis. According to the International Law, it is marked by an environmental objective resulting from public interest. In this sense, marine energy conversion does not generate greenhouse gas emissions and its impact on the marine environment is generally minimal. With the help of these renewable energies, States will be able to respect their supranational commitments, particularly regarding climate change. In addition, the Law of the Sea provides legal certainty in the use of ocean space, by defining not only rights but obligations to coastal states. At the European level, legal certainty is connected to the target of at least 20 % share of energy from renewable sources in the Union's gross final consumption of energy by 2020, and is especially encouraged by the North Seas Countries' Offshore Grid Initiative in the context of the Europe's emerging renewable energy market. On a National perspective, the analysis of Comparative Law highlights the best practices related to offshore renewable development in terms of promoting investment and sustainable ocean management.

L’Algérie est un pays producteur et exportateur d’hydrocarbures, mais cette source de revenus qui fait vivre plus de 30 millions d’habitants sera tarie dans moins de 30 ans. Le spectre de l’après-pétrole se manifestera au moment où l’on s’attendra le moins sans qu’aucune mesure n’ait été prise pour y faire face. L’une des solutions de substitution aux hydrocarbures est de développer le secteur du tourisme. C’est un enjeu économique qui assurera des ressources en devises et leurs effets positifs sur la balance des paiements. Sur le plan social, il permettra d’accroître l’emploi sachant qu’il existe un écart important entre la demande et l’offre en matière de travail. C’est également un enjeu environnemental puisqu’il nécessite l’existence de potentialités de qualité pour assurer sa pérennité.C’est dans ce cadre que nous avons inscrit notre recherche pour un développement touristique en Algérie dans sa dimension intégrée, respectueux de l’environnement, en étayant notre travail en prenant pour cas d’étude Alger, la capitale étant la vitrine du pays. Pour ce faire, nous avons établi un état des lieux du tourisme en Algérie et des impacts environnementaux sur les espaces touristiques. Le tourisme n’est pas développé malgré la diversité des potentialités et les multiples stratégies de développement touristique qui se sont succédées. Par ailleurs, sachant que le secteur touristique subit les impacts des autres activités sur l’environnement, nous avons détaillé les sources de dégradation en revenant sur le cas algérois qui montre bien la situation environnementale catastrophique qui prévaut dans le pays. Tout cela a permis de dégager des perspectives / Algeria is a producing and exporting country of hydrocarbons, but this revenue stream which made live more than 30 million inhabitants will be dried up in less than 30 years. The spectre of it after oil will show itself as we shall expect least unless no measure was taken to face it. One of the substitution solutions to hydrocarbons is to develop the sector of the tourism. It is an economic stake which will assure resources in currencies and their positive effects on the balance of payments. On the redundancy plan, it will allow to increase the employment knowing that there is a distance mattering between the demand and the offer regarding work. It is also an environmental stake because it requires the existence of quality potentialities to assure its sustainability.It is in this frame that we registered our research for a tourist development in Algeria in its integrated dimension, environment-friendly, by supporting our work by taking for study case Algiers, the capital being the showcase of the country. To do it, we established a current situation of the tourism in Algeria and the environmental impacts on the tourist spaces. The tourism is not developed in spite of the diversity of the potentialities and the multiple strategies of tourist development which followed one another. Besides, knowing that the tourist sector undergoes the impacts of the other activities on the environment, we detailed the sources of degradation by returning on the case of Algiers which shows well the catastrophic environmental situation which prevails in the country. ll this allowed to clear perspectives for a development integrated of the tourism on the coast of Algiers, which can be adapted to every entity of the algerian coast.

Port of Kaohsiung is the most important harbor of southern Taiwan and it was once the third biggest cargo harbor in the world. Recently, the ranking of Port of Kaohsiung dropped from the 3rd to the 13th, thus the Central Government of Taiwan has introduced a plan to enhance the situations. ¡§Urban Renewal Project of Kaohsiung Port Railway Station,¡¨ involves the development planning of many sites and the waterfront regeneration along the Kaohsiung Harbor. This paper argues that the sustainability is the key of success of the project. This paper will (1) to discuss the gains from the economic developments, (2) to examine the details and discuss the coming challenges and potential obstacles in pursuing greater socio-economic goodness, and (3) outline the possible solutions, practices, and mechanisms which might be useful in attaining a sustainable development of Kaohsiung Harbor by studying other countries¡¦ success and failures in their waterfront redevelopment projects.

La question de la remontée des niveaux marins et du recul du trait de côte est aujourd'hui une préoccupation de premier ordre face à laquelle les sociétés sont en attente de connaissances et de propositions. Or, les littoraux les plus menacés, les côtes basses, sont d'une part le siège de pratiques séculaires, de "défense contre la mer" et ont, d’autre part, été investis dans une période récente par des activités touristiques tournées vers l'exploitation des plages. Cette vulnérabilité physique et sociale explique notre choix pour les littoraux correspondants aux trois communes de Vias, Agde et Marseillan (golfe du Lion). Ces terrains réunissent un ensemble de caractéristiques qui en font un terrain laboratoire propice à l’observation et au traitement de cette problématique. L’érosion et la submersion marine ont marqué l’espace et les paysages de ces territoires. Face à cette situation de vulnérabilité se pose la question de l'adaptation des systèmes socio-économiques qui se sont développés dans ces espaces et de la résilience des territoires. La résilience désigne la capacité à anticiper, à réagir et à rebondir après un événement perturbateur. Cette approche nous permet de comprendre comment la société locale réagit face à des situations de vulnérabilité et comment se construisent les capacités d’adaptation et de résilience dans sa dimension territoriale. L’approche monographique est mobilisée dans notre travail à partir des entretiens semi-directifs, l’objectif est de confronter la notion théorique de la résilience des territoires à sa réalité pratique. À travers, ces trois territoires, il s’agit d’apporter des connaissances empiriques afin de décrypter les enjeux et révéler un modèle de développement axé sur la littoralisation des activités. Nous proposons à la fin de ce travail une nouvelle démarche, la Résilience Intégrée de Zones Côtières (RIZC), pour dépasser la complexité du réel et entretenir les solidarités entre tous les acteurs concernés. La RIZC permet de maintenir un niveau d’activité à l’aide des capacités de la souplesse du système afin de limiter les conflits d’intérêts entre public et privé et renforcer leur confiance mutuelle. / Rising sea levels and coastline recession have become a major issue about which society requires knowledges and solutions. The shorelines most threatened are low seacoasts which are both places of century-old traditions of coastal protection and localities exploited for tourism attracted by their beaches. This material and social vulnerability explains our choice of three municipalities: Vias, Agde and Marseillan (France, Gulf of Lion). These cases highlight features that permit pertinent observations on the subject. Erosion and coastal flood have shaped their landscape and planning. Can socioeconomics systems adapt to this new vulnerability? Resilience is the capacity to anticipate, react and bounce back after a disturbance. This approach allows us to understand how local communities react to vulnerability and plan new forms of resilience and adaptation. We use semi-structured interviews to build monographs and contrast theoretical resilience against real life experiences. These three territories are used to gather empirical knowledge in order to clarify the issues at stake and the need to abandon the concentration of activities on shorelines. Finally, we discuss how a new approach known as integrated coastal zone management; can overcome the complexity of the real situations encountered and underpin solidarity between all the stakeholders. Using a more versatile system, integrated coastal zone management, can help to maintain activities, limit conflicts of interest between public and private stakeholders and strengthen their mutual trust.

As preocupações com a integridade e o equilíbrio ambiental das regiões costeiras decorrem do fato de serem as mais ameaçadas do planeta, justamente por representarem para as sociedades humanas um elo de ligação e de intensa troca de mercadorias entre si, com a exploração desordenada e muitas vezes predatória de seus recursos naturais, tornado-se, já na era industrial o principal local de lazer, turismo ou moradia de grandes massas de populações urbanos. A vocação de uso de determinada paisagem esta relacionada às funções que a mesma desempenha. O que ocorre é que o padrão de desenvolvimento adotado e a atual configuração sócio-econômica determinam usos que nem sempre coincidem com a sua melhor utilização. A fim de subsidiar futuros planos de uso e ocupação racional do solo das áreas naturais adjacentes ao Balneário Cassino (Rio Grande, RS), de acordo com os preceitos do Gerenciamento Costeiro Integrado, desenvolveu-se um Dianóstico Sócio-Ambiental da área dentro de abordagem sistêmica. Foram considerados principais componentes e processos urbanos e ambientais, definidos a partir da interpretação de aerofotografias, levantamentos de campo quali-quantitativos e informações bibliográficas. Os resultados são apresentados na forma de tabelas, quadros, levantamentos fotográficos, modelos diagramáticos conceituais, e mapas temáticos, que permitiram entender a organização estrutural e funcional da paisagem, e fundamentar uma ordenação espacial dos usos desta área, de modo a adequá-los às suas especificidades ambientais, histórico-culturais, sócio-econômicas e legais. / The integrity and the environmental equilibrium of coastal zones are increasingly becoming a concern to environmental scientists. Coastal environments are one of the most threatened in the world. Besides, they represent, to the human societies, a link of connection and intense exchange of merchandise amongst each other, with disordered and, at many times, predatory exploration, becoming, already at the industrial age, a main site of leisure, tourism and habitation of large masses of urban population. The vocation of a determined landscape is related to the functions and roles it plays. What actually occurs is that the development pattern adopted and the actual socio-economics determine the uses, which not always coincide with its best utilization. In order to assist future plans of rational use and occupation of natural areas adjacent to Cassino's Bathing Resort (Rio Grande, RS), in agreement with the Integrated Coastal Zone Management, a social-environmental diagnosis of the study site was developed using the systemic approach. The main environmental and urban processes and components were considered. They were defined based on aerophotos interpretation, quail-quantitative field survey and bibliographic information. The results, presented in the form of tables, photographic surveys, conceptual diagrammatic models and thematic maps, allowed to understand the structural and functional organization of the landscape and to establish a spatial ordering of land use to adequate them to their environmental, historic-social, socioeconomics and legal specificities.

El objetivo de la tesis es establecer un marco metodológico para la identificación de indicadores GIZC orientados a problemas y temas de interés, para contextos geográficos específicos. La tesis parte de la idea de que los sistemas de indicadores, utilizados para medir el estado de la costa y la implementación de proyectos de Gestión Integrada de las Zonas Costeras (GIZC), deben orientarse a problemas concretos de la zona de estudio y que su validez debe ser comprobada no sólo por la opinión de los expertos, sino también por la percepción de los usuarios y por el análisis estadístico cuantitativo. / The problem addressed by this thesis is the identification of site-specific and problem-oriented sets of indicators, to be used to determine baseline conditions and to monitor the effect of ICZM initiatives.The approach followed integrates contributions from coastal experts and stakeholders, systems theory, and the use of multivariate analysis techniques in order to provide a cost-effective set of indicators, oriented to site-specific problems, with a broad system perspective.A systems approach, based on systems thinking theory and practice, is developed and tested in this thesis to design models of coastal systems, through the identification of the system's components and relations, using the contribution of experts and stakeholders.Quantitative analysis of the system is then carried out, assessing the contribution of stakeholders and using multivariate statistics (principal components analysis), in order to understand the structure of the system, including relationships between variables.The simplification of the system (reduction of the number of variables) is one of the main outcomes, both in the participatory system's design and in the quantitative multivariate analysis, aiming at a cost-effective set of key variables to be used as indicators for coastal management.

In this thesis, it has been aimed to analyse the efforts undertaken by the European Union (EU) to stimulate and enhance Integrated Coastal Zone Management (ICZM) in the European coastal zone, within the context of the EU Environmental Policy. ICZM was formally accepted in the international community during the 1990s as an alternative to traditional sectoral coastal zone management approaches. It aims to establish an integrated management mechanism among different sectors to minimise resource use conflicts in coastal zones. Sustainable development constitutes the underlying idea of ICZM, the overall goal of which is to achieve sustainable development in coastal zones. Therefore, ICZM is founded on the internationally accepted principles of sustainable development. Chapter 17 of Agenda 21, which is a formal output of the United Nations Conference on Environment and Development, made an explicit statement of the need for integrated management of coastal and ocean areas to achieve their sustainability and called the participating nations to take the necessary steps. The EU, being at the forefront of such international developments and embraced sustainable development as a broader policy objective, is devoted to take concerted action in terms of protecting the European coastal zone and fostering ICZM action at the EU and the Member States (MSs) level. Since the early 1990s, the EU institutions began to put substantial effort to achieve this goal, and initiated dedicated actions. Those existing and the foreseen EU actions are elaborated within the context of this thesis. For the time being, the EU ICZM action is a flexible one without a regulatory binding instrument for ICZM. The ongoing EU ICZM action is based upon the existing EU policies and legislation. Within this framework, the central aim of the EU is laid down as to ensure the coordination and integration of these diversified policy objectives and legislative instruments to contribute to sustainable management of the European coastal zone. Since they constitute the backbone of the current EU ICZM efforts, those policies and legislation are also investigated within the scope of this study. This thesis accentuates the importance of concerted EU action in terms of stimulating ICZM action in Europe and the probability of a future EU level devotion towards a more regulatory approach in the longer term.
