Analyse sociale de cycles de vie : les cycles de vie des représentations paysagères de l'éolien

Abstract : The increasing use of the transition terms in the public debate contributes to the emergence of new research methods whom geographers begin to apprehend. Transition invites to consider a new action framework. In the matter of energy domain, the transition concept involves geographers in their socio-spatial interpretations. This new spatiotemporal frame, where are introduced the notions of territorialisation of the energy and the reversibility, provides an opportunity to consider these issues from a reinterpretation of the space-time couple. In this context, the thesis aims in understanding and analyzing of socio-spatial mechanisms tested by the renewable energies development, especially wind turbines. The specificity of this approach may be a geographical rendition of the Life Cycle Assessment method. For this purpose, the thesis requires the concept of landscape in its dynamic meaning. However, the life cycle assessment invites us to reshape the idea of landscape dynamics according to the notion of event. The thesis explores the arrival of a wind turbines project as an event and it focus on its sudden emergence, the induced socio-spatial destabilizations and the individual and social adaptations. The purpose of this research is to investigate a Social Life Cycle Assessment of the landscape representations of the wind energy. This ambition faces a time constraint. The allowed time of a PhD thesis faces political times and the times of the experience. Created events or suffered events impact the socio-spatial representations differently and over various timescales. Considering a diachronic study brings about rethinking the epistemological and methodological issues raised by a corpus which gathers several types of data, from different sources and which would be analyzed together. The analysis is led on discourses and especially on spatial textual references along with the individual sensibilities revealed when a wind turbines project is initiated on territory. The thesis tracks the life cycle steps of windpower-events that we interpret according to the socio-spatial context of the study terrains.
