L'intérêt de cette thèse est de surmonter le conflit entre la protection de l'environnement et le besoin du développement. En effet, le droit de l'environnement, en ayant comme objectif l'amélioration de l'état de l'environnement, peut être contraire au besoin du développement économique. Une première hypothèse est que le droit à l'environnement est l'outil juridique, qui, à travers son double caractère, à la fois comme droit et à la fois comme devoir, peut constituer la base afin de compenser l'équilibre entre l'état émergent de l'environnement et les besoins sociaux et économiques. Une deuxième hypothèse est que cette contradiction peut être surmontée en utilisant le concept du développement durable, qui promeut l'équilibre dans la satisfaction des trois besoins essentiels de notre société, à savoir les conditions économiques, environnementales, et sociales et culturelles. L'objectif de cette thèse est d'examiner les possibilités d'appliquer le concept du développement durable aux cinq plus grandes îles de la Méditerranée (Sicile, Sardaigne, Chypre, Corse, Crète), en proposant un cadre juridique commun pour la protection de l'environnement. / Slands are territories where the tensions between the protection of the environment and economicdevelopment appear in an exaggerated manner. From one hand, island's ecology needs strict natureconservation measures, because of its vulnerability. On the other hand, the limited available spacein islands, combined with an augmented demand to develop, nourishes the territorial conflicts. Lawis called to manage such conflicts, thus arises the interest of reflecting on the theoretical basis of anIslands Law.This work adopts a territorial approach that studies the Mediterranean island space by usingmanifold tools of social sciences.

Each year storms impact coastal areas, sometimes causing significant morphologic change. Cold fronts are associated with increased wave energy and frequently occur during the winter months along many coasts, such as the Atlantic and Gulf of Mexico. The higher wave energy can be responsible for a large quantity of the sediment transport resulting in rapid morphologic change. Using streamer traps, the vertical distribution of onshore-directed sediment transport during two different cold fronts on two low-wave energy beaches (i.e., along the northern Yucatan and southeast Florida) were compared with the resulting morphologic change. The objectives of this study are to: 1) analyze the grain size distribution (statistics) of sediment transported during a cold front, 2) compare the vertical sediment distribution throughout the water column, and 3) compare characteristics of bed sediment to the sediment within the water column. Understanding the changing grain size distribution of bottom sediments in comparison to directional transport (throughout the water column) should help determine the sediment fraction(s) being eroded or deposited, which could greatly improve predictions of storm-induced morphology change. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

O objetivo deste estudo foi avaliar se a estrutura da comunidade da meiofauna, das famílias e dos gêneros de Nematoda apresentam alterações devido à atividade antrópica na área próxima a Estação Antártica Brasileira (CF), em comparação com um controle (BP). A densidade média (ind.10cm-²) da meiofauna total variou entre 7028 (? 1529) e 16245 (? 12282) nos 20-30 m e entre 1569 (? 928) e 7088 (? 10338) nos 50-60 m, corroborando os valores altos já descritos para a zona rasa antártica. Nematoda foi dominante (>90%), seguido de Nauplii e Copepoda. 65 gêneros e 3 subfamílias de Nematoda foram encontrados, pertencentes a 24 famílias. Daptonema, Halailamus, Dichromadora, Sabatieria, Aponema e Sphaerolaimus foram dominantes nas duas profundidades, mas tiveram densidades mais altas nos 20-30 m relacionadas à maior biomassa de clorofila a. Não foram identificadas alterações na estrutura da comunidade da meiofauna, das famílias ou gêneros de Nematoda que pudessem ter sido causados por impacto antrópico. Porém, a riqueza e a diversidade das famílias e dos gêneros de Nematoda foram menores em CF, o que sugere um possível impacto, sendo importante a continuidade do monitoramento e a inclusão de outras áreas de referência. O nível taxonômico de família foi o mais apropriado para um estudo de monitoramento da zona costeira rasa antártica, visando o melhor custo-benefício. / The aim of this study was to verify if meiofauna, Nematoda family and genera community structure show modification caused by human activities at the Brazilian Antarctic Station (CF), in relation to a reference area (BP). Mean meiofauna densities ( ind.10 cm-²) ranged from 7028 (? 1529) to 16245 (? 12282) at 20-30 m and from 1569 (? 928) and 7088 (? 10338) at 50-60 m, being high as already described for the Antarctic coastal zone. Higher densities at 20-30m were correlated to more chlorophyll a and sand. Nematoda were dominant (>90%) followed by Nauplii and Copepoda. 65 genera and 3 subfamilies of Nematoda were found, belonging to 24 families. Daptonema, Halailamus, Dichromadora, Sabatieria, Aponema and Sphaerolaimus were dominant at both depths, but had higher densities at 20-30 m, which were correlated to higher chlorophyll a biomasses. Analysis for all levels of taxonomic resolution, separated the samples between depths, but not between areas, so differences caused by human impact were not detected. Number of genera ranged from 12 to 34 and diversity from 1.57 to 4.22 bits/ind, both being higher at 50-60m at BP, suggesting that an impact might have occurred, so monitoring should continue and be extended to other control areas. Identification of Nematoda to family level would be enough to evaluate environmental impact of the coastal antarctic zone.

The coastal zone of Belize is home to the largest recorded number of the threatened Antillean manatee (Trichechus manatus manatus) within the species' Caribbean range. The objectives of my study were: (1) to determine long-term trends in aerial survey counts and indices of the manatee population in the coastal zone of Belize; and (2) to examine the seasonal change in manatee distribution among habitats in the coastal zone. Standardized extended-area aerial surveys were conducted along the entire coastline of Belize in the dry and wet seasons of 1997, and 1999 - 2002. Manatees were counted in five habitat categories: cay, coast, estuary, lagoon, and river. Total sightings per survey ranged from 90 to 338; the greatest number was counted in the 2002 wet season. Calf percentage ranged from 5 to 13. A slight negative trend in total counts was significant for dry-season, not wet-season surveys, indicating an interactive effect of season and year. Based on analysis of variance, the Abundance Index (transformed manatee sightings per hour) did not differ significantly among years, although it varied significantly within year by season and habitat by season. In applying a spatial approach, the general survey route was buffered 1 km on both sides, and 1 km grids were overlaid and classified by habitat type. The presence or absence of each cell for each survey was used in likelihood ratio tests of the single and interactive effect of season and habitat. The Index for river habitat was higher in the dry season, while cay habitat was higher in the wet season. Overall, near-shore habitat (estuary, lagoon, and river) showed a higher Index than did the offshore habitat (cay and coast) although the total number of sightings was higher offshore. Considering the interactive effect of year, season, and habitat, long-term studies are needed, in both seasons, and among all habitats to account for variation. Continued broad-scale surveys, along with metapopulation analysis would fine-tune the understanding of specific sites, enhancing integrated coastal zone management for protected species and their habitat systems.

Coastal regions provide a lot of resources and benefits for all the humankind. For economic growth, these resources are needed. On the other hand, coastal resources should be maintained and preserved in some limits. Sustainable development is aimed to set a balance between economic growth and preserving the nature. Determination of the yacht carrying capacity is a major step for sustainable development. In this thesis study wind-induced water circulation in semi-enclosed basins are carried out in order to reach the yacht carrying capacity for Fethiye Bay. Hydrodynamics of bays is very complex, mainly affected by wind and wave climate and sea bottom topography. The sea bed profiles at the bay changes under winter and summer storms of different speeds and directions. This case study will be carried out with the developed methodology. The present structure of Fethiye Bay will be analyzed and necessary measurements will be proceeded. Moreover, two more cases will be studied besides the present conditions. Circulation models will be applied to the study case according to reached data. For this purpose, Finite Volume Coastal Ocean Model (FVCOM) numerical model will be used.

This study focuses on the determination of locality of Integrated Coastal Zone Management studies in Turkish legislation and applicability. Accordingly the process of the awareness of necessity for Integrated Coastal Zone Management in the world, related definitions, concepts and implementations, international institutional organizations and planning management experiences of different countries are firstly investigated. Afterwards coastal legislation, coastal planning process, recent studies in order to regulate authority in Turkey and as a result management, legislation, authority is evaluated. Finally Izmit Gulf (Kocaeli- Yalova) Integrated Coastal Zone Planning and Management Project are examined as a case study. State of Izmit Gulf, basic principles, zoning decisions and suggested strategies and activities are scrutinized. This study is also the first compilation concerning recent changes in planning legislation in Turkey related to ICZM studies.

Coastal zone become the object which is used to develop when the economy developed quickly and population increase. As a result of coastal zone is a region which involves economy, environment, ecology, and engineering. We must integrated many factors and coordinated related groups. Then we can achieve the goal of sustainable development. The research involved the knowledge and experiences from Europe, American, and Japan. Except they used a construct of Integrated Coastal Zone Management (ICZM) to think the questions, they combined ecology, water conservancy engineering, social economic activities, and environmental protection. Then they used DSR framework as the foundation to establish the system which evaluated sustainable development of the coastal zone, and they can develop the system dynamic model analyzing the coastal management in many conditions. Land subsidence is a potential crisis, it grows obviously with the time and has the impact to the environment., When typhoon occurs in the west part of Taiwan coastal area, draining which is unable to operate may cause flood, mole avalanche, seawater intrusion and soil salinization. First we must understand the origin and the management of land subsidence, then we can make the effective strategies by researching different background and geography characteristic of the region. As a result of land subsidence involves economy, environment, ecology and engineering, the process of land subsidence is a complex problem which has multiple causes. This problem usually involves time-delay and long-term effect. System dynamics is an approach that is used to describe, explore and analyze the procedure, information and the boundary of organizations in complex systems. Such model is good for solving dynamic complex problems with non-linearity, causal circulation, information feedback and time-delay as long as the estimative parameter fall in its confidence level. The object of the research is to inspect land subsidence in the Pingtung plain. Therefore, this study proposes to find strategies which is suitable to solve interested problems according to integrate social-economic and ecologic-environment development. The framework of the research is based on the DSR (Driving forces-State-Response) index, and it makes evaluated factor from collecting domestic and foreign literature. Then we selected the important factors and its weight value by using the method of AHP (Analytic Hierarchy Process) to visit the expert and the scholar. According to above, we developed the model of system dynamics and build confidence in the model. In addition, the result of the simulation can provide good supporting information for decision makers by using the model for several strategies simulation and making the index to represent the performance of simulation analysis.

Coastal zone is the region of rapid socio-economic development and the habitat of various marine lives. With the increasing complexity of land use, integrated spatial planning is important and indispensable to the development of coastal zone. Coastal environment is a complicated system with highly dynamic environment, coastal zone planning needs to achieve the objectives of environmental protection, economic development and ecological sustainability. To solve this planning problem, either analytic or simulation approaches have been used. However these two approaches have their own demerits in problem solving. The purpose of this research is to develop a model combing analytic and simulation methods to solve spatial planning problem in complicated dynamic marine environment. Through combined with Multi-Objective Programming, Fuzzy Sets Theory and System Dynamics, a spatial planning model of dynamic multi-objective programming approach to the coastal zone spatial planning will be constructed. It could be used in coastal zone development predicting, regional and city planning and marine policy decision making.

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.
