Missions

The post-doctoral fellow will be involved in two tasks: 1) identifying the relevant territorial scales of the circular bioeconomy towards an interterritoriality of transition trajectories (the bio-waste flow approach) and 2) inventorying drivers (the bio-economic sector actor approach). The study areas for this project are the urban areas of Nantes and Rennes.

Activités

Her or his main tasks will be to:
- Development of a methodology to overcome the interdisciplinarity of the two approaches (by flows and by actors) presented by bio-economic trajectories, based on the theoretical frameworks of territorial ecology and political-industrial ecology, with the aim of defining scenarios that could eventually serve as a basis for comparison in the territorialized assessment of their environmental performance;
- The definition of reference scenarios for the transition trajectories identified in the Nantes and Rennes metropolitan areas;
- Collecting and formatting data from local players to produce a Material Flow Analysis (MFA) inventory for use with Life Cycle Assessment (LCA) tools;
- Analysis of the drivers of territorial metabolism in the bioeconomy-biowaste sector. This will involve the decentralization of waste treatment, metabolic outsourcing or relocation, spatial and technical regulatory constraints and their evolution over time, power relations between stakeholders, historical quantification of resource and bio-waste flow circulation, etc.
To this end, he/she will be asked to :
- Develop a flow analysis of the socio-economic metabolism of territories linked to the circular bioeconomy. Based on bio-waste flows, all related nexuses (energy, phosphorus, nitrogen, etc.) will also be identified.
- Carry out interviews with public, private and associative players in the sectors present in the regions, at different operational and functional stages, and at different territorial scales.
- To provide significant added value in data analysis and the characterization of trajectories in the articulation of territorial scales.

Compétences

PhD in planning/environmental sciences. Previous experience in a territorial approach to biomass/biowaste is desirable. Expertise in LCA and/or MFA methods is a real plus.
Good interpersonal skills, ability to work independently, interviewing skills, command of scientific English, ability to synthesize, openness and capacity for interdisciplinary dialogue.

Contexte de travail

Context
As part of the project BEECOME2 (Biowaste, Environment, ECOnomy and Metabolism) funded by ADEME, UMR ESO is offering an 11-month post-doctoral position in spatial planning, starting on October 10, 2023.
The aim of the project is to identify the socio-economic, spatial and metabolic drivers for the construction and evaluation of transition trajectories towards circular and sober management of territories' bio-waste. The aim of the project is to enable the construction of different transition trajectories based on all these drivers, the determination and definition of the articulation of the spatial scales concerned, towards a regime of interterritoriality for bio-waste (from kitchens, gardens, agri-food industries, crop residues, livestock effluents) and the environmental assessment of these trajectories.
The BEECOME 2 project is based on the proof-of-concept described above for a "drivers-scenarios-trajectories" model, and aims to move from proof-of-concept to a decision-making tool to help regions understand the drivers influencing their transition trajectories and, if possible, be in a position to influence them. The idea is to make the proof-of-concept more robust by working in greater depth on the metabolism of territories through the analysis of waste flows, but also their socio-economic metabolism, in order to compare metabolic functioning and stakeholder strategies. This increase in robustness will also require the removal of obstacles such as the relationships between drivers and the production of household bio-waste, and the distribution of the latter among the various recovery channels. All these elements will then be formalized mathematically using a dynamic numerical model to simulate transition trajectories. Two study areas will be explored: the urban area of Rennes and the urban area of Nantes.
He or she will be supervised by researchers Jean-Baptiste Bahers (territorial ecology) and Lynda Aissani (LCA specialist).
