Vers une gouvernance anticipative des changements globaux. L’emprise des interdépendances socioécologiques sur une métropole estuarienne : Bordeaux Métropole et l’estuaire de la Gironde

Abstract : The thesis aims to analyze the emergence of anticipatory governance in order to understand how adaptation to global change - defined as all anthropogenic environmental disturbances - transforms the governance of estuarine metropolises (based on the case of the Bordeaux metropolis). The politico-ecological footprint of these metropolises on the estuarine peri-urban and rural areas is exacerbated by the growing socio-ecological interdependencies to govern the risks of flooding, loss of biodiversity and drinking water supply. The rise in importance of these major issues, which constrains the sustained attractiveness of estuarine metropolises, promotes dedicated public policies that go beyond the metropolitan institutional scale, extending to its adjacent functional territories. These policies, which involve highlighting the socio ecological interdependencies between metropolitan areas and their estuarine hinterlands, compel local authorities and stakeholders to renew their approaches in terms of urban and territorial planning. The emerging paradigm shift in urban/rural relations is reinforced on the one hand by recent territorial reforms (MAPTPAM, GEMAPI, NOTRe), which confirm the influence of cities beyond their administrative territory, and on the other hand by the socio-ecological functions of hinterlands within a metapolitan territorial system. The sociological analysis of these issues is based upon an original theoretical framework of socio-ecological interdependencies able to link the territorial conditions associated with the emergence of anticipatory governance facing global change. Through various ways of exposure, these socio-ecological interdependencies reveal themselves as public problems and as strategies of actors in public and private decision-making arenas. Three case studies serve as an empirical basis for this thesis: flood-submersion risk management, metropolitan water drinking supply and, governance of urban biodiversity.
