Organisation et gestion du littoral - évaluation des ressources humaines : réfugiés environnementaux et aménagement du territoire en Europe et en Méditerranée : Etudes de cas : La Gironde (L’estuaire) en France et Thessalonique (Les deltas d’Axios-Loudias-Aliakmonas) en Grèce.

Abstract : The present thesis seeks to define a conceptual framework in order to examine the populationmovements related to environmental risks. For about twenty years, several terms haveemerged to describe thedisplaced people such as: environmental refugees, eco-refugees,climate refugees or eco-migrants. The terms and the status attributed to these populations arelargely dependent on the nature, strength and speed of the environmental event contributing totheir displacement. It is therefore necessary to specify the criteria in order to avoid anyconfusion and to be able to assess the physical flows generated by the environmentaldisasters. Our analysis is focused on the risks of submersion and inundation along the coastand in the delta areas associated with rise in the sea levels. In view of these increasing risks, it is absolutely necessary to set up a "proactive strategy", based on the triptych protection -prevention - anticipation. For each type of risk considered, this strategy requires, beyond thedelimitation of the geographical areas concerned, quantification and qualification of thepotentially affected populations. Consequently, the main aspect of our problematic combinestwo types of vulnerability:the firstdue to environmental disasters’ risks such as floods and thesecondto increasing population pressure. Finally, we chose to examine in our study two areashighly subjected to flood risks such as the Gironde estuaryin France and the Axios -Loudias-Aliakmonas Deltas in Central Macedoniain Greece trying to estimate the potential size ofpopulation movements in 2025 and 2050.
