Socio-ecological issues, territorial metabolism, wealth creation: application to the Maurienne Valley

This thesis work aims to analyse the socio-ecological issues of human wealth-creating activities through the coupling of quantitative models for the analysis of territorial metabolism and qualitative and socio-economic approaches. The Maurienne Valley is the field of application of the thesis, the agri-food sector being the wealth creation activity mainly analysed in this study.

The research effort focuses on the coupling of quantitative models for the analysis of the territory's metabolism (material flow analysis, life cycle analysis, multi-scale analysis) with qualitative and socio-economic approaches (analysis of stakeholder groups and their interactions: proximity, power relationship, legitimacy, motivation). The monetary and intangible dimensions of the sector (information flows, traditional know-how, controlled techniques and territorial specificities) are also part of the analysis. The relationships between the agricultural subsystem and other wealth-creating activities are examined, including interactions with tourism, residential, industrial and hydroelectric sectors.

The objective of the thesis is finally to provide a better understanding of the paths of territorial transition to sustainability and the resilience of the territorial system in the face of disturbance factors that may threaten its sustainability. A particular effort is being made to ensure that the methodology deployed can be transposed to other sub-regional or departmental territories.
