Full textSpatial Data Infrastructures (SDIs) have been implemented over the last twenty years in particular in order to contribute to Environmental Policy by improving geographic information access and sharing processes. Given the current dynamics of both production and circulation of environmental geographic information, the general aim underlying this research is part of the general framework for a better understanding of environmental management practices. This research focuses specifically on French SDIs and their contribution to Integrated Coastal Zone Management (ICZM), a complex form of territorial governance for which the collection and sharing, particularly via SDIs, of geographic information have been identified, since the 2000s, as a major component on which to found coastal and marine public policies. However, the real contribution of SDIs depends on the answers they provide to their users. From a methodological perspective, this PhD is implemented by an exploratory research approach focusing on the usages and needs of coastal stakeholders as well as on the complex and dynamic nature of SDIs. The research approach is divided into two phases: - A national online survey examined by a triple analysis: Statistical analysis, Social Network Analysis (SNA) and thematic analysis;- A sub-national case study based on semi-structured interviews with key informants and analyzed thematically and by Data Flow Diagrams (DFD). These data collection and analysis techniques have been selected and implemented in an integrated and complementary approach to enable understanding, explanation and generalization of the "SDI system" in the context of ICZM. For each phase of the research, three types of results emerged: the profile of users, the type of SDIs playing a role in the management of French coasts, and their contribution to the management of these areas. The above-described research has resulted in a contribution to the knowledge of SDI appropriation and the associated information flows

Full textThis thesis investigates the usages of spatial representations (maps, simulations, 3D representations…) described in the literature as essential to any process of Integrated Coastal Zone Management (ICZM). The aim is to understand how spatial representations contribute to implementing and organising ICZM processes at a local scale.An ethnographic methodology is implemented in two case studies in France (Brest and Lorient) in order to observe spatial representations in concrete and tangible situations of uses. Circumstances, goals and uses conditions are analysed as well as interactions that they induce with stakeholders, contributing (or not) to move on the process to a next step. We used the actor network’s theory to analysed a corpus made of 15 non-participating observatories, 24 semi-structured interviews with the stakeholders and 300 documents (reports, slides show…) including 115 spatial representations.The results show that the ICZM’s stakeholders use only a few potentialities offered by the Geographic Information Technologies. Furthermore, spatial representation’s uses are mainly intended to construct and stabilise the actor’s network rather than to organise the territory as generally described in the literature.Finally, the spatial representation’s status (inscriptions, intermediary objects, actants) vary slightly. Indeed, spatial representations are mainly used as intermediary objects, helping stakeholders to collaborate

Full textCoastal systems where sediment transport is perturbed by engineering interventions on the shoreline and shoreface commonly provide fine examples liable to throw light on these links. This is especially so where shoreface bathymetric datasets, which are generally lacking, are collected over time, enabling more or less fine resolution of the meso-scale coastal sediment budget. Agadir Bay and the city of Agadir together form one of the two most important economic development poles on the Atlantic coast of Morocco. Using a combined methodological approach based on wave–current modelling, bathymetric chart-differencing, determination of shoreline fluctuations, and beach topographic surveying, we highlight the close links between variations in the bed of the inner shoreface and the bay shoreline involving both cross-shore and longshore sand transport pathways, sediment budget variations and new sediment cell patterns. This work discusses also the morphological changes and evolution of Agadir Bay beach (Morocco) in response to eight storms between January 2014 and March 2014. A comparison is carried out of the evolution and variability of the beach in a sector of the bay protected by the commercial harbour of Agadir relative to a sector down drift of the harbour that is more exposed to waves, and changes affecting the beach following these storms are examined. Wave influence is evaluated using numerical simulations. The results show that despite being of relatively low intensity, the two first storm events, and especially storm 1, are responsible for major beach morphological changes

Full textSlands 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

Full textOver the centuries society has modified its representation of marine space, moving from the concept of «empty oceans» to that of «saturated seas ». Indeed, in addition to « traditional» established activities (commercial fishing, navigation etc,) have been superimposed the intensification of certain practices (extraction of marine aggregates, leisure navigation etc. ) and also new activities which, until now, have been purely terrestrial or coastal but which are destined for development in the open sea (marine renewable energy, offshore aquaculture etc. ). In the face of these new developments, the necessity of conserving the marine environment has also encouraged the multiplication of marine protected areas (marine nature parks, Natura 2000 sites, etc. ). There is thus an increase in the demand for maritime space which the actual availability of space cannot respond to, outside of integrated management enabling the cohabitation between ail the various maritime activities. But the particularities of maritime space call for a specific approach. Nowadays, lntegrated Coastal Zone Management (ICZM) is a procedure which is recognized at an international level in response to these issues. But its applications are still too often limited to an experimental stage and the feedback on experiments show that they are limited to coastal land or to confine maritime spaces. It is in this context that Maritime Spatial Planning (MSP) would seem to be useful, enabling the extension of the principles of ICZM towards the sea. After studying the implications of MSP, in particular thanks to the analysis of existing experiences at an international level, this thesis focuses on an evaluation of the position of France in relation to MSP in the context of the elaboration of its strategy of Integrated Management of the Sea and Coastline (IMSC). The theoretical aspects of MSP are compared to the conditions on the ground at different levels and, in particular, to those of the maritime basin of Lorient. This approach enables the identification of key elements and issues related to the application of MSP in the context of metropolitan France

pour optimiser la gestion de l'information et de la connaissance dans les dispositifs de GIZC. Compte
tenu de l'hétérogénéité des ressources informationnelles nécessaires et réparties chez des acteurs variés de l'importance de l'information géographique dans ce domaine, nous proposons, en réponse à cette problématique, une solution qui s'appuie sur l'utilisation d'un service de métadonnées pour décrire et localiser l'information existante et d'un référentiel sémantique pour intégrer et partager la connaissance experte. Ces outils sont accessibles sur un portail Web. Le premier implémente la norme ISO 19115 relative à la gestion de métadonnées pour l'information géographique), le second s'appuie sur un modèle d'ontologie a priori qui structure l'inventaire des concepts du domaine et exprime la connaissance qui leur est associée. Les concepts spatiaux possèdent des propriétés géométriques qui permettent leurs représentations cartographiques géoréférencées et des relations spatiales normalisées d'après les travaux de l'Open Gis Consortium. Le référentiel sémantique sert pour le contrôle de la valuation d'éléments clés du service de métadonnées, en particulier les éléments de descriptions thématique et spatiale (avec une interface cartographique). Le gain en qualité d'indexation améliore la localisation d'information. Le détail du référentiel est consultable sous la forme d'une base terminologique, d'un réseau sémantique et d'un atlas cartographique (basé la norme relative aux Web Mapping Service de l'OGC) dans le cas des concepts spatiaux. De tels systèmes distribués sont capables d'interopérer et partager les métadonnées, l'information géographique, ou les concepts qu'ils hébergent.

Full textThe sea plays a vital role in regulating climate and in maintaining ecological balance. The oceans and the sea constitute a source of wealth, an immense reservoir of food resources and of employment for many people. The Mediterranean Sea is a sensitive ecosystem, subject to strong pressures derived from human activities, such as fishing, oil and gas exploration, dumping of waste and other matter in the sea, maritime transport, transfer of aquatic invasive species via ballast water and littoral tourism. France, severely affected by the sinking of the Amoco Cadiz, the Erika and the Prestige, took numerous initiatives not only at an international but also at a regional level. The complexity of the marine pollution problem, due to the diversity of polluting factors and to their diffuse sources, has favored a regional approach. This approach has resulted in the adoption, at a national, regional and international level, of a network of policies, legislative texts, programs and action plans in the field of marine environment protection. It constitutes a stifling body of rules, comprising preventive and repressive measures. The institutional and legal complexity of marine protection hinders, however, the effective protection of the marine environment. ln this context, the international community encourages the implementation of an ecosystem approach to oceans. At European level, the adoption of the Framework Directive «Strategy for the Marine Environment» favours a consistency between different EU policies as well as an integration of environmental considerations into ail policies related to the sea. Furthermore, the effectiveness of European legislation in the field of the fight again marine pollution, has been reinforced by the adoption of a common framework of liability with regard to the prevention and remedy of environment damage

Full textOn observe que des configurations spatiales récurrentes apparaissent quant à la localisation des conflits d'usage. Cependant, le mode d'expression et les formes de régulation diffèrent selon les types de territoires (lagunes, zones périurbaines, départements, communes, etc.) et les types de conflits (urbanisation et aménagements, protection des espaces et des espèces et gestion de l'eau et des déchets).
L'analyse des conditions d'émergence, des modes d'expression et des formes de régulation à une échelle locale révèle les interactions fortes entre les réseaux d'acteurs et les mutations spatiales. L'apparition d'un conflit bouleverse les pratiques et les représentations socio-spatiales. Les territorialités se redessinent et participent d'une part à la restructuration des réseaux d'acteurs, et d'autre part à l'évolution des stratégies et des comportements des acteurs qui influencent en retour l'organisation du territoire.

Full textIn the context of climate change and sea level rising, the activities of coastal communities can increase the vulnerability of the seashore to coastal erosion particularly in small developing islands as Anjouan in the Comoros archipelago where the human density on the coast is quite heavy. This thesis focuses on sandy beaches, studied as a system. The monitoring of topographic profiles of beaches and landscaped geoindicators show that a large part of the sandy coast of Anjouan is very degraded and eroded. The erosion is mainly localized to areas of high human pressure, including beaches subjected to the extraction of sediments . Combined with natural hazards, the erosion due to human activities generates serious damages for the economy, society and environment of Anjouan, including the degradation of ecosystem services on which the government could draw to initiate the development of the island . To reduce the vulnerability of the coastline to erosion, walls are built with the financial support of international and regional bodies, but they are inefficient and the risk of coastal degradation is even greater. For beach users, causes erosion are to be found in the work of the man and not in nature. Minimizing this risk requires socio-economic measures to reduce anthropogenic degradations. This study shows that a policy of ICZM in Anjouan in the Comoros and elsewhere will only be effective if those responsible for its implementation take into account local realities and perceptions of coastal users
