7.1.1 Sankeytool

• Name:
  Web app for drawing Sankey diagrams
• Keyword:
  Sankey diagram
• Scientific Description:
  A Sankey diagram is a visualization of sectors that are arranged in layers: in each layer, sectors are represented by nodes which are organized and aligned vertically. Flows are only possible between distinct layers, therefore they are mainly horizontally oriented. Each flow is represented by a graphic link (e.g. a Bézier curve) having a width corresponding to the flow volume. The main objective is to visualize an economic sector or another structure in the most efficient way, in other words the representation of the elements must facilitate human understanding of the structure. Literature offers several criteria which can be used and optimized to achieve this objective. This software generates Sankey diagrams automatically. The creation includes several steps, each of them focuses on the resolution of a specific optimization problem. The formulation of these is inspired by the article "Optimal Sankey Diagrams via Integer Programming" written by Zarate et al. in 2018. The software includes an implementation of this and several new methods. They are based on solving linear programming optimization problems.
• Functional Description:

  The software is an online web app that allows manual and automatic sankey diagram plotting. Among the functions these diagrams can be exported in svg or pdf format.

  A Sankey diagram is a type of visualization of flows (of data, physical entities, money, etc.) between sectors (for example, economic sectors). The main entries of the software are a table comprising a description of these sectors and the flows, as well as the flows' volume. The software contains functions that aim at computing an optimal disposition of the flow diagram (position of sectors and flows on the produced chart), according to different possible criteria. For instance, a disposition that minimizes the number of crossings between flows or that contains as horizontal as possible flows.

7.1.2 STA-Explorer

• Name:
  Socio-Technical Alternatives Explorer
• Keywords:
  Decision aid, Ecological transition scenarios
• Functional Description:

  The software is a decision support tool that allows to:

  * Describe an economic model, in different territories with different types of actors, in terms of bio-physical exchanges (to take into account the interactions between sectors, for example the fact that renewable energies consume materials which in turn require energy to be extracted and transformed) * Describe a Socio-Technical Alternative (STA), i.e., an arrival point in the future that is coherent from a biophysical point of view (as opposed to the description of a past situation) * From this description, the software allows the alternative to be evaluated by "reconciling" by optimization the parameters controlling the value of the flows rather than the flows themselves.

  Data reconciliation, Operational research, Constraint Programming
• Scientific Description:
  Data reconciliation and interval reduction algorithms for MEFA (material and energy flow analyses).
• Functional Description:
  To facilitate a meaningful comparison, multiple algorithms have been developed. A checker is proposed to ensure that the provided results are well-formed and respect the problem’s constraints. A visualization program is also proposed, along with an algorithm that provides the optimum, to compare the difference with it. A random instance generator has been developed to carry out larger-scale tests. Finally, numerous algorithms have already been described and a benchmark of real instances is offered to establish a preliminary comparison framework.

8.1.1 Evaluation of the robustness of the World3 model and the validity of its conclusions

Participants: Serge Fenet, Pierre-Yves Longaretti.

A scientific collaboration was launched in 2024 between the STEEP team (Pierre-Yves Longaretti and Serge Fenet) and the Tripop team (Arnaud Tonnelier). In this context, Antoine Cordoba began a two-year postdoc contract in the Tripop team in September 2024, and is working to continue the work initiated by Mathilde du Plessix on the iconic World3 model before her thesis was interrupted in 2022. The interest in the model has been revived in the last decade or so, in light of the growing concerns about planetary limits and the impact of human activity on natural systems, and we aim at re-evaluating both the robustness of the model and the validity of its conclusions. During her thesis, Mathilde has performed an extensive analysis of the parameterization choices made by the authors of the model, based on a comprehensive sensitivity analysis made possible by modern computing power. This analysis allowed us to identify the most influential parameters in an objective way. In the continuation of this work, Antoine is working on a fine-grain analysis of the inner dynamics of the model based on the relative importance of its feedback loops, taking over the incomplete work of Mathilde du Plessix on this topic. As the relevance of the model gathers a new importance in the emerging Anthropocene era, the results of this work will be the first comprehensive loop structural dominance analysis of the World3 model, letting us objectively describe the temporal dynamics of the feedback loops linking the variables of interests. The work will next focus on the level of endogeneity of the model.

8.1.2 Feasability of the energy transition

Participants: Antonin Berthe, Pierre-Yves Longaretti, Emmanuel Prados.

Louis Delannoy's thesis showed that the question of peak oil, largely forgotten since the 2008 crisis, needs to be addressed afresh. On the one hand, oil is the most critical of the three fossil fuels, both in terms of its range of uses and of the difficulty of its fast substitutability. On the other hand, oil supply will start to decline considerably by 2030/2040, due to falling energy returns on investment combined with falling gross production, even assuming that untapped resources will be brought on stream as quickly as possible in the future. The question is not about reserves, which are considerable, but about flows. From an economic point of view, the problem posed is whether demand will fall as fast or faster than oil supply, particularly from a long-term growth perspective. Both public discourse and the vast majority of integrated models from the scientific community assume that this is the case under the impact of the energy transition, but this assumption is not self-evident.

The aim of Antonin Berthe's thesis is to quantify the tension dynamics of oil supply and compare it with the possible deployment speed of a transition to electricity, particularly in transport (which accounts for 2/3 of our oil use), in order to assess the possibility of avoiding a long-term global structural macroeconomic crisis. The thesis is in its final stages, as are the articles that form its core.

The main result of the thesis is that a gap between oil demand and supply necessarily arises around 2030 in a BAU scenario in terms of global economic growth where the saturation of the fraction of electric vehicles in the world fleet reaches 25%, and delayed only by a few years (2035-2040) when this saturation level is increased to 50%. These two saturation levels are shown in the thesis to bracket all reasonable expectations on the electric vehicle market share in the future.

8.1.3 CRISIS model

Participants: Pierre-Yves Longaretti, Hugo Martin.

The CRISIS model (Cascading Reactions in Society's Interconnected Systems) is designed to address the role of energy tensions amplified by financial speculation on structural macroeconomic crises. In particular, this model aims at pinpointing the dynamical conditions leading to long term economic decline and its consequences. This work is a direct continuation of the theses of Louis Delannoy and Antonin Berthe in terms of global risks associated to the upcoming oil supply contraction, although the focus shifts from “physical” models to macroeconomic ones.

The model relies on the stock-flow consistent macroeconomic modeling framework, which is a self-consistent approach to macroeconomic dynamics. The framework enforces all macroeconomic identities, while making no specific choices for the behavioral equations characterizing the different sectors of a specific model (banking, production, households, etc). As such the framework accomodates as well orthodox or heterodox economic theories, although it is mostly used by the heterodox post-keynesian school of economic thought.

The model is now in its advanced production stage. A central BAU scenario has been calibrated and simulated, without any tension on resources or any financial speculation. This idealized setting has been used to bracket the relevant domain of variation of the main parameters of the model. The speculation module of the model is now also calibrated. The results of runs performed in presence of speculation are presently analyzed, in particular with the objective to characterize the spectrum of financial market variations on the production sector, from normal, sedate fluctuations to large magnitude crises, and comparison with data on real financial markets behavior. A first article is in its final stages of completion and should be submitted shortly. As an aside, an article has been written on the sensitivity analysis of a simpler but somewhat related macroeconomic dynamical model, as a stepping stone to produce a sensitivity analysis of the much more complex CRISIS model 54.

Dynamical simulations with tensions on energy supply are in a very early stage. This work should be completed and submitted in 2025.

8.1.4 Systemic crisis propagation: study of the health sector

Participants: Enzo Baquet, Valérie d’Acremont, Serge Fenet, Pierre-Yves Longaretti.

In January 2022, Enzo Baquet started a PhD thesis focusing on the analysis of the dynamics of the propagation of intra- and inter-sectoral disruptions in the context of short-term crises (week to year). While this work should ultimately lead to the creation of a generic modeling methodology, it first focuses on the thread given by a particular case study: in the context of civil health infrastructure, how can the impact of an electrical blackout spread to different subcomponents of the health sector, and impact health services. In order to answer to this questions, Enzo spent one year (from september 2023 to september 2024) at the Unisanté center of the University of Lausanne, our partner in this project. He deployed a participatory approach based on semi-directive interviews with several actors of the civil health system and key stakeholders of the Vaud district 41. The goal was to gather caregivers' perceptions of an interruption of electricity supply, the direct and indirect impacts they could identify, their willingness or unwillingness to act, and the actions they might already be taking. Interviewees also explored the role that they would see themselves playing in possible continuity plans that might be put in place by the health sector. Enzo is now processing and analyzing these interviews, in order to: a) interpret the results to identify the most salient weak points and their sequence of occurrence, and then build a representation of the intra- and inter-sector connections that they bring to light; b) propose a sequence of recommendations to be implemented by the sector in order to minimize impacts, or even anticipate them.

8.1.5 Post-growth lessons from real world examples

Participants: Albert Bouffange, Pierre-Yves Longaretti.

How can we understand the specific institutional arrangements of an economy that reduces its material base in a planned/organized way? Crossing the analytical prisms of political economy and social metabolism, this thesis examines a few real historical examples, at macro or meso level, that can highlight the socio-economic rules of the game specific to reducing the environmental footprint, in order to anchor reflections on post-growth and ecological bifurcation. Cuba during the “Special Period” is the first case study of the thesis 36. This is a relatively unique experience of the macro dynamics of the contraction of flows in the economy and the consequent institutional adaptations. The second case study focuses on the disarmament process in France and the partially planned downsizing of the armed forces and the defense industrial base. It provides elements of a meso-scale response to the problems of dismantling economic activities, in an institutional context closer to that of present-day Western societies than Cuba.

On the methodological side, this interdisciplinary thesis builds upon the material flow analysis tools developed in the STEEP team and on the French political science regulation theory for institutional and political analyses. These two approaches are combined to provide unique insights in the thesis case studies. The thesis was started in the Fall of 2022, following an internship on the Cuba case study. The main supervisor is Agnès Labrousse, from the Triangle political science laboratory in Lyon, with P.-Y. Longaretti as co-supervisor.

8.2.1 Territorialization of planetary boundaries

Participants: Guillaume Mandil, Gwendoline de Oliveira Neves, Damien Rieutor.

The aim of Damien Rieutor's PhD thesis is to provide a framework for downscaling the concept of planetary boundaries to the territorial level. This concept is an undeniable success of Earth system science. This success has attracted the attention of other scientific fields and sectors, notably public institutions, transforming reflections on local implementation of the concept into a major scientific and societal issue. Numerous attempts to implement the concept on a sub-global scale have raised a number of questions about this approach, and have highlighted the difficulties of operationalizing 'Planetary Limits' locally. These difficulties are due mainly to the dominant approach employed, which seeks above all to spatialize the Planetary Limits framework. The literature review we have carried out in this work examines this approach with regard to the distinction between the framework of Planetary Limits (biophysical dimension, spatial vision) and the concept of Planetary Limits (sociological dimension, territorial vision). Our results show that, by focusing on the biophysical aspects of the framework, it obscures the anthropological objectives of the concept and reduces the importance of the social specificities of the context 72. In this way, we demonstrate the limits of spatializing the framework. It hinders the concept's local operationalization, weakening its appropriation by territorial stakeholders and maintaining inconsistencies between the concept's global essence, its sub-global translation and local socio-biophysical specificities.

To overcome these limitations, this work will propose a method for territorializing the approach used to establish planetary limits at the global level. The main idea is to apply the notion of environmental limit to the satisfaction of a human need in the territory under consideration. The aim of the method will be to identify the bio-physical systems on which the satisfaction of the need depends, and then to identify the state variables that guarantee the stability of these systems.

8.2.2 Analysis of public policies dedicated to building waste

Participants: Jean-Yves Courtonne, Quentin Desvaux, Catherine Figuière, Guillaume Mandil.

Since November 1st, 2020, Quentin Desvaux has been involved in a CIFRE PhD thesis with the STEEP team, the CREG lab and the DPCTD (Direction de la Prévention, de la Collecte et du Traitement des Déchets) of Grenoble Alpes Métropole. The goal is to support the local authority in deploying a waste management strategy for the construction sector that is consistent with the specific features of its territory. This work comprises several activities: analysis of construction waste management and processing channels (based in particular on the team's material flow analysis tools); operational implementation of policy measures; coordination of working groups; perpetuation of the dynamics initiated with the stakeholders involved; restitution, promotion and dissemination of Quentin's work through public institutions. It is a contribution towards the decompartmentalization of the academic and professional sectors. An article was recently published in a special issue of the journal Géographie, Economie, Société30, see also 37. It illustrates how the national Producer-Extended Responsibility policy comes in contradiction with the local zero-waste and circular economy policy on several theoretical and practical dimensions.

8.2.3 Bridging the gap between the Musiasem and the Supply-Use Tables frameworks

Participants: Albert Bouffange, Jean-Yves Courtonne, Jérémie Klein, Emmanuel Krieger, Peter Sturm.

During a winter school organized in Grenoble in December 2023, during which we hosted Mario Giampietro (ICTA, UAB), we observed that Giampietro's Musiasem framework is highly relevant for sustainability analyses, but that the community has not fully embraced it due to its complex conceptualization and challenging vocabulary. We therefore examined how to bridge the gap between Musiasem and the Supply-Use Tables framework, which is commonly used in the field, to enable mutual enrichment of both approaches 32.

8.2.4 Numerical tools for data and parameter reconciliation

Participants: Alexandre Borthomieu, Thibaut Coudroy, Jean-Yves Courtonne, Vincent Jost, Guillaume Mandil, Peter Sturm.

Data reconciliation is an important building block for MFA (material flow analysis) and other problems with a similar structure, such as in chemical plant modeling. The goal is to construct a consistent representation of, for instance, an economic supply chain or a set of processes (production processes, chemical ones, etc.) that are related through flows (of materials, substances, goods, etc.). This representation usually has a graph structure and numerical values to be determined usually concern the volume of the mentioned flows as well as technical coefficients characterizing the processes. These values are determined from data, which are often only partially available, subject to uncertainties, and incoherent. The data reconciliation problem entails the estimation of coherent numerical values from such data, using constraints, such as mass preservation, aggregation constraints, or others that might be available (such as known inequalities between certain values). Data reconciliation can be followed up by an estimation of the values' uncertainty. In our applications, uncertainties are usually represented by uncertainty intervals. The above mentioned constraints often allow to narrow down given uncertainty intervals – we speak of “interval reduction” here.

This year we have developed several methods for interval reduction (PhD thesis of Alexandre Borthomieu). Their development was motivated on the one hand that the gold standard method, consisting of solving many linear programs ($2n$, $n$ being the number of the problem's variables), is time-consuming, and on the other hand that a previously developed method (MAJLOOP) is very fast but provides sub-optimal results. Sub-optimality is due the fact that this method processes one constraint at a time during its iterative procedure, which prevents it from reducing intervals to their minimal size. We developed several methods that function like MAJLOOP, but which uses linear combinations of constraints in order to improve the result's quality. Various ways were tested to produce appropriate linear combinations, including matrix factorisations and random sampling. These methods were tested on our benchmark datasets; results demonstrate a good compromise between computation time and accuracy.

Alexandre Borthomieu also developed several methods to visualise results of reconciliation methods. They consist in computing appropriate orderings of data-points of a set of graphs, such as to minimise for instance the number of crossings of graphs.

Data reconciliation is used in representing an observed supply chain or other set of interrelated processes. STEEP also aims at developing tools to conceive, model and assess potential socio-technical alternatives (STA's), e.g. for territorial prospective exercises. When modeling STA's, reconciliation problems also appear, but they are of a different nature. The construction of an STA relies on choosing involved processes (such as transformation processes in agro-food chains or industrial production processes) and connect them according to the material or other flows they are related through. Now, for any given type of production, several alternative processes may be available (such as organic and conventional agriculture) and it is natural for a user to think of an STA in terms of relative shares between such alternative processes. Obviously, when defining desired shares for different sets of alternatives processes, the induced flows among all them are in general not coherent. This creates the need of a new reconciliation problem: instead of operating on flow values, it operates on the mentioned relative shares. We speak of parameter reconciliation 94. This year we generalised the original parameter reconciliation formulation. The original formulation uses a linear least squares cost function, i.e. consists of penalising deviations between user-set and reconciled values through the bell-shaped Gaussian function. While this is the default choice and leads to simple solutions for optimisation, intended end-users of our software STA-Explorer (section 7.1.2) might find it more intuitive to define other ways of penalising deviations (such as box-functions or triangular ones). These in turn give rise to cost functions for the reconciliation problem that are no longer of linear least squares type and that require, for instance, to solve linear or non-linear programs. These results are yet to be published.

8.2.5 Energy flow analysis for the Briançonnais area

Participants: Mathilde Boissier, Jean-Yves Courtonne, Nils Ferrand, Emmanuel Krieger, Peter Sturm.

Modelling work was carried out by Emmanuel Krieger, a PhD student in the team, to represent the energy flow diagrams of the PETR of Briançonnais, Écrins and Guillestrois-Queyras, in order to support the debates in a concertation process on the territory's energy policy (see section 8.2.7). The aim is twofold: for the inhabitants of the territory, it is to provide information on how it operates in order to inform the decisions, and for our team, it is to test the use of these diagrams and to combine them with an approach based on socio-metabolic vulnerabilities, i.e. vulnerabilities arising from the territory's specific way of operating.

As a first step, two workshops were organised at the beginning of December 2024 with about ten inhabitants to carry out an initial assessment of these diagrams. A diagnosis was then presented to around forty citizens and stakeholders as part of the concertation process. Further workshops will be held in the first half of 2025 to refine the scientific conclusions related to the use of these diagrams and the socio-metabolic vulnerability approach.

Most of the diagrams have been constructed using open data. However, these data do not cover all the energy-related issues identified for this territory, so modelling was carried out to quantify the missing parts. These include electricity imports and exports, the disaggregation of sectoral energy uses, the breakdown of final energy into useful energy, the allocation of energy to different categories of users, and the energy used by tourists to enter and leave the territory. These models have been produced in various ways: by generalisation from sub-regional data, by down-scaling from national data, through harmonisation by making data comparable, etc. All the data produced in this way were then reconciled with the open data already collected to produce the energy flow diagrams 58. Figure 5 shows an example of a diagram produced this way.

8.2.6 Serious games for the exploration and analysis of sociotechnical alternatives

Participants: Mathilde Boissier, Thibaut Coudroy, Jean-Yves Courtonne, Serge Fenet, Nils Ferrand, Vincent Jost, Emmanuel Krieger, Sam Mellier, Roger Pissard, Nicolas Revilla Lopez, Peter Sturm, Marine Valette.

Accounting in biophysical flows is one grid of analysis providing insights on the sustainability of socio-technical alternatives. These tools are indeed relevant to highlight systemic effects (interdisciplinary understandings, spatial and temporal scales) on resources and important pressures to consider for the transformation of territories. Yet, this biophysical flow vision remains for expert use only, whereas one of the challenges of transition territories is to involve the populations in participatory processes. Among diverse participatory tools, serious games have long since proven their ability to sensitize to sustainability issues, facilitate learning and support changes. We aim to develop several games to play with material and energy flows while discussing the futur of their territories. This involves every stage of modeling (capturing reality into a biophysical and governance model, making this model simple enough to be played with, and bring back this model into the real world to collectively transform a territory's organization), game design as well as lab and field experiments. After developing two simple games in 2022 (see last year's report), we have designed a modeling framework – TransKey – based on social metabolism. Software implementation of a TransKey simulation platform has started last year and has continued this year, through the internship of Thibaut Coudroy (see Section 7.1.3 and 56, 55), with the support of Roger Pissard and Laurence Boissieux from the Inria Grenoble SED service. After the analysis of the experimental qualitative data gathered on the first version of a single-user game (see last year's report), a new version of the game has been developed. This version is multiplayer and already implements all the scientific objectives expected in the design. This version can be played either as a material board or as a video game. It has been tested and is expected to lead to publication in 2025. See figure 6 for illustrations.

The internship of Sam Mellier allowed to establish a state of the art review on the calibration of (serious) games and to make proposals for such calibration approaches 35, 59, 60

8.2.7 Participatory exercises in territories

Participants: Mathilde Boissier, Jean-Yves Courtonne, Nils Ferrand, Emmanuel Krieger, Peter Sturm, Marine Valette.

Since about 2021, we have started to work towards the creation of participatory exercises, to assist in the face of transition challenges in territories. See 85, 57 for a brief overview of our philosophy. We have been working on two territories, as follows.

The first project is the PETR du Grand Briançonnais (Pôle d'Equilibre Territorial et Rural – Briançonnais, Ecrins et Guillestrois Queyras), a so-called intercommunalité (grouping of 3 communautés de communes, comprising a total of 36 municipalities), located in the French Alps. This territory experiences recurring conflicts around the construction of hydroelectric power stations in mountain rivers, usually opposing energy producers, elected officials and NGO’s dedicated to nature preservation. On this background, the presidency of the PETR launched the initiative of a territory-wide participatory process, to be steered by STEEP and Nils Ferrand’s group at INRAE, covering the issues of energy, biodiversity, water, and territorial development. The year 2022 had seen the launch of the project with individual interviews and first meetings to better understand the territorial context and initiate the participatory process. Simple Sankey diagrams illustrating energy flows on the territory (created using the software described in Section 7.1.1) had also been put to the test. In 2023, procedural work has been conducted to formalize the project, helping the PETR to get funding from the Banque des Territoires (granted in the end of 2023). We have also conducted workshops to make stakeholders organize the participation (PrePAR approach), which ended up into a step and actions plan, as well as a governance for the process to support. 2024 has seen the real takeoff of this project. Indeed, with the unlocking of the Banque des Territoires funding, a project manager has been recruited by the PETR to animate and manage the project. A steering committee, a scientific committee as well as a citizen panel have been formed. A training ans sensitizing phase, aimed at everyone on the territory, has been lead with workshops about participation, water, energy, with a conference about climate change impacts for mountain territories, webinars about several other subjects, and a field trip. A detailed diagnosis about energy flows has also been conducted with first workshops to evaluate their impact. This work has been realised by Emmanuel Krieger, as part of his phd. Other diagnosis (socio-economic, biodiversity for example) have also been realised in a lighter way by a group of students from the master TEET (ENSE3). To complete this diagnostic, a participatory observatory has been launched to encourage anyone living in the territory to report some knowledge needs or important information for the following of the dialogue. A new game, EnerKey, has also been created (as part of Marine Valette's internship), see section 7.1.4. Based on TransKey, this game gathers the territory's stakes in this dialogue and brings people to play with complexity and resource nexus to understand better the situation, realize its complexity and start building options to implement. The tests have been realised and the game is ready to be widely played in 2025. Finally, 2024 has been a year of meeting with elected officials and institution to keep working on the legitimacy of this process and ensure its continuation. 2025 is supposed to end up the process with different steps : get several people playing EnerKey, discuss the territory's orientations, build an action plan and implement it. In a scientific perspective, 2025 is also supposed to bring scientific valuation with different articles expected (about the impact of energy flow modeling in the dialogue process, about the game EnerKey, about the process in its entirety).

The second territory is the greater Grenoble area and the perimeter of the programmed participative process is the establishment of an interterritorial food plan (Projet Alimentaire inter-Territorial (PAiT) de la grande région Grenobloise). Within the Scalable project (see Section 9.3.2), STEEP has been involved both in quantitative/analytical modeling and in the development of a participative approach 25, 51, 52.

8.2.8 Participatory reasearch on energy sufficiency

Participants: Mathilde Boissier.

Launched thanks to a IRGA exploratory funding, it involves 4 researchers from different disciplines (energy modeling, spatial planning, participatory research). This project aims at exploring how to discuss energy sufficiency collectively in the society. It also aims at documenting about interdisciplinary research work , with a reflective dimension about academic research. 2024 has been the beginning of the project with and analysis of the literature and sharing knowledge and methods between the members. A first workshop has been built and tested three times (with students and through the PETR du Briançonnais project, see section 8.2.7) to make participants consider collective sufficiency. 2025 is the last year of this exploration and should involve a synthesis document, 6 months internship on this subject and the application to further funding.

8.2.9 Modeling human resources in the health sector

Participants: Hannah Gelblat, Jean-Yves Courtonne, Valérie d'Acremont.

This project is based on the ongoing PhD thesis of Hannah Gelblat in Humanities and Social Sciences of Medicine and Health at the University of Lausanne, under the supervision of Pr. Valérie d'Acremont. The aim is to determine, for two contrasted scenarios, how many people with what type of training would be involved to care for communities and ensure a fair access to healthcare in Switzerland. Our model will represent contrasted scenarios for the Swiss health system - a “business-as-usual” scenario and an “alternative” scenario. With this approach, we hope to allow an informed arbitration between several organizational choices, thanks to a transparent representation of their resource requirements and a qualification of their potential benefits and limitations. The suggested system changes have been identified in the literature: WHO recommendations, experts’ insights or other countries’ practices. The alternative scenario will show a health system focused on health promotion and prevention, task-shifting from physician to non-physician health workers and transfer of efforts from hospitals to ambulatory care. Model parameters are selected based on their potential to address either of the following key global challenges faced by health systems:

1. Shortages of health professionals: the World Health Organization announces a “ticking timebomb”, saying that “without immediate action, health and care workforce gaps in the European Region could spell disaster” (World Health Organization, 2022)
2. Increase in health care needs due to ageing of the population and chronic disease increases;
3. Lack of access to primary care due to system organization;
4. Planetary global context - we intend to conceive new alternatives within a ‘post-transition’ perspective, considering the impact of environmental changes on health and the associated global risks brought by dependence on energy and pharmaceuticals.

The metastructure of our model is shown on Fig 8. The system organization is viewed as a key to determine both the sustainability of provision of human resources needed and the satisfaction of care needs of the population.

For this work, we rely on the social metabolism paradigm 89. This approach is inspired by the metabolism of living organisms: it compares the inputs into a system, the different elements within the system and the benefits provided by the system to the organism which it is part of. In social metabolism, we apply the same approach to a human activity sector by looking at physical resources and by describing the inputs of the sector, how it functions, and the benefits it provides. Our application of this approach on the health system is shown on fig 9. We draw inspiration from the flagship method in the field: material flow analysis (however accounting for working hours instead of mater or energy). Quantitative implementation of the model generally relies on data reconciliation 77 and, in our case, we will specifically utilize dynamic material flow analysis calculations to simulate the evolution of flows and stocks over time 99. The following parameters are to be tested in the model in order to improve health coverage and the sustainability of human resources provision:

• Effect of prevention and promotion on the prevalence of certain diseases or healthcare needs,
• Transfer of the efforts and of human resources from hospitals to ambulatory care, especially primary care centers (following the example of Nordic countries),
• Transfer of more responsibilities from physicians to non-physicians,
• Adjustment of working time (for physicians and non-physicians) and effect on job satisfaction and quality of care,

8.2.10 Exploring trade-offs in the relocalization of productive acitivities

Participants: Léon Fauste, Jean-Yves Courtonne, Mathieu Mangeot, Christine Solnon.

Léon Fauste started his PhD in oct. 2021 and took a "gap year" in school year 2023-2024 to study geography. The original motivation of his work was to explore how the optimization framework proposed by 93 could be combined with the social metabolism approaches developped in the STEEP team in order to highlight trade-offs in the relocalization of productive activities. In other words, the aims is to inform the public debate on the following question: for a given activity, to what extend and on which dimensions is relocalization beneficial or detrimental, and for who? Until now, Léon lead his research in three direction. First, he conducted an interdisciplinary litterature review to identify and link the diffent concepts associated to to idea of organizational scale. Core concepts (globalization, proximity, territory, delocalization and relocalization) as well as characterizing concepts (dependency, self-sufficiency, supply or production basin, economy of scale, economic integration, concentration and decentralization, specialization and diversification, short supply chains, territorialization, connectivity and localness) were thusly identified. Second, Léon questioned the identity between indexes of concentration of indexes of specialization from three different perspectives: a mathematical angle, a simulation angle and a historical data analysis angle (with databases on agriculture, energy and on international economic activity tables). He concludes that while the indexes are correlated, there are cases where concentration and specialization are not (or not completely) congruent, emphasizing the need for a more rigorous distinction in the litterature. Finally, Léon is finishing a toy model showing how trade-offs between self-sufficiency, satisfaction of local needs and environmental footprints can be explored with constrained optimization. The case study is agriculture and relies on previous data gathered by the team. These three works are planed to be submitted in international journals in 2025.

8.2.11 Reconfiguration of Cuba's metabolism after the collapse of the Soviet Union

Participants: Jérémie Klein, Albert Bouffange, Jean-Yves Courtonne, Renaud Metereau, Guillaume Mandil.

It is rare for a country's economy to suffer a sharp contraction in its supplies of raw materials essential to its metabolic functioning. One of the rare cases in history is Cuba in the 1990s. After the collapse of the USSR in 1991, which was Cuba's main trading partner, the island saw its imports of several raw materials plummet. Major changes were made to cope with this shock: this period is known as the “special period”. To study the metabolism of the territory during this period, data from the Food and Agriculture Organization of the United Nation, the International Energy Agency, scientific and grey literature were collected. Then, using the data reconciliation tools of the team, analyses of material and energy flows enabled us to take a closer look at the Cuban metabolism before and after the collapse of the USSR 34.

9.1.1 Participation in other International Programs

Serge Fenet is involved in a collaboration with the University of Lausanne (UNIL), Department of Ecology and Evolution (Jérôme Gippet) and the University of Düsseldorf (Mathematics and Natural Sciences faculty, Computational Cell Biology Group) (Charles Rocabert), working on the development of the MoRIS model of propagation of invasive species 27.

9.2.1 Visits of international scientists

9.2.2 Visits to international teams

In February 2024, Jean-Yves Courtonne (STEEP team) and Claudia Binder (HERUS team, EPFL) organized a two-days seminar in EPFL in order for the teams to meet and discuss potential subjects of collaboration. Presentations and discussions were organized in 3 sessions: (i) Tipping points, systemic risks and resilience, (ii) Transdisciplinarity, participation and games, (iii) Material Flow Analysis (MFA) and coupling MFA with other methods. The seminar gathered 6 permanent researchers of the STEEP team (including Nils Ferrand) and about 10 researchers, postdocs and Phd students from the HERUS team. Possible student exchanges were discussed but have not begun so far. However, for her expertise on social metabolism and on the links between quantitative assessments and social sciences, Claudia Binder was asked to be a member of the thesis committee of Hannah Gelblat.

9.3.2 SCALABLE – Metabolism of agricultural biomass: multi-scale representations, vulnerability analysis and evaluation by local stakeholders

Participants: Mathilde Boissier, Jean-Yves Courtonne, Nils Ferrand, Sophie Madelrieux, Guillaume Mandil.

Project funded by ADEME

Duration: 2021-2024 (36 months)

Coordinator: Sophie Madelrieux (Inrae Grenoble), Jean-Yves Courtonne for Inria partner.

Partners: LESSEM (Inrae Grenoble), Auvergne-Rhône-Alpes Énergie Environnement, TerriFlux, Parc Naturel Régional de Chartreuse, STEEP (Inria Grenoble).

Keywords: agriculture value chains, multi-scale analysis, multicriteria analysis, vulnerabilities, participative evaluation.

Abstract: SCALABLE focuses on agricultural biomass, on the different transformation steps (supply chain) from production to consumption, at several geographical scales (national, regional, local). The projects aims at improving knowledge on material and organizational vulnerabilities of territories with respect to these supply chains: to what extent are the needs of the local population satisfied in a sustainable way, and without transferring vulnerabilities to other territories? This work will be conducted by coupling an analytical approach (use of descriptive models) with a deliberative approach (evaluation by local stakeholders). It will also lay a basis for assessing the relevant scales of relocation of the different sectors of the value chains. The work at the national level with agricultural technical institutes resulted in two communications 33, 38 presenting the methodology, the multi-stakeholder working process, and a proposed analytical framework for interpreting flow diagrams (food sovereignty, competition for resource use and bioeconomy, consumption patterns).

9.3.3 BACCFIRE

Participants: Jean-Yves Courtonne.

Project funded by Ademe

Duration: 2022-2024

9.3.4 SOCLE

Participants: Jean-Yves Courtonne.

Project funded by Ademe

Duration: Dec. 2024 - Nov. 2027

Partners: INRIA, INRAE, TerriFlux, Le Basic, IDELE, CTIFL, IFCE.

Keywords: Agri-food sectors, Material Flows, Footprints, Employment, Co-design

Abstract:The development of the bioeconomy raises questions about the competition for the use of agricultural resources, which must meet food (human and animal), energy, and material needs. Furthermore, the observation of planetary boundaries being exceeded makes it urgent to precisely identify the causes of environmental impacts, which can be difficult to disentangle due to globalized production-distribution networks. Beyond these environmental issues, French agriculture must today address economic and social challenges to renew itself and meet consumer demands. At the intersection of all these concerns, the SOCLE project aims to improve knowledge of the biophysical structure of agricultural product flow networks in France and abroad, as well as their environmental impacts and employment implications. To this end, it brings together research partners, supply chain stakeholders, and two consulting firms.

The primary scientific objective of the project is to provide, for a recent year, a database describing:

• National and international flows of agricultural products, leveraging the highly detailed knowledge of a Flow Reference Framework that has been updated and expanded to describe French industries,
• The environmental pressures exerted by French industries in terms of energy, nitrogen, land use, and blue water (irrigation) use with a footprint perspective, i.e., focusing not only on what happens within French territory but also in the supplying countries,
• The direct and indirect employment linked to French industries.

From an operational standpoint, the project aims to enrich discussions on sectoral strategies that simultaneously consider planetary boundaries, international dependencies, and social and economic realities. Collaboration with industry stakeholders is planned throughout the project.

9.3.5 Research collaboration agreement with the PETR du Briançonnais

Participants: Mathilde Boissier, Nils Ferrand, Emmanuel Krieger, Peter Sturm, Marine Valette.

Duration: Dec. 2023 - Dec. 2025

Partners: Inria and Pôle d'Équilibre Territorial et Rural du Briançonnais, du Pays des Écrins, du Guillestrois et du Queyras.

Abstract: This bilateral collaboration agreement formalises and finances the activities described in section 9.4.1.

9.4.1 Supporting the dialogue on energy, PETR du Grand Briançonnais

Noting the difficulties in reconciling the Climate and Energy Plan (PCAET), the expectations of environmentalists and the management of local authorities, the President of the Pôle d'Équilibre Territorial et Rural du Briançonnais, du Pays des Écrins, du Guillestrois et du Queyras (PETR) asked the INRIA STEEP and INRAE G-EAU teams to set up and coordinate a research-intervention to support the territorial stakeholders (see the associated website). The aim of this dialogue is to define the region's energy policy, considering resource management and environmental impacts, while involving stakeholders throughout the process: in the construction of a participation plan and its implementation, including participatory modeling and the creation of an action plan to be implemented in the future. This collaboration involves a number of challenges, such as a joint search for funding, the mobilization of citizens and the decision-making nature of the process, as well as the scientific production (on the mobilization of biophysical accounting on territories) associated with the project (see 8 for further details). Following the researchers' support of the PETR's application to a funding from the Banque des Territoires, a convention between INRIA and the PETR has been signed to formalize this partnership both institutionally and financially (see section 9.3.5).

9.4.2 Contribution to the local food plan of the Grenoble area

As part of the SCALABLE project, the meat, dairy and cereal supply chains were studied based on extensive stakeholders (transforming industries) interviews and data analyses. Results were presented and discussed during two workshops. More generally, the SCALABLE project (which ended in Dec. 2024) was presented to the technical committee of the Pait (local food plan). See section 8.2.7 for more details.

9.4.3 Supporting the building waste policy of Grenoble Alpes Métropole

Quentin Desvaux is currently finishing his CIFRE PhD thesis in partnership with Grenoble Alpes Métropole. He was involved in the organization and animation of several workshops gathering stakeholders from public and private backgrounds and aiming at understanding concrete lock-ins for increasing building waste reuse. See section 8.2.2 for more details.

9.4.4 Local Risk Report for the Grenoble Metropolitan Area

The local authorities of Grenoble and adjacent territories2 have launched a long-term initiative entitled l'Atelier des Futurs. Its goal is to reconsider public action with regard to the complexity of current and coming issues (social, economic, environmental) and often contradictory injunctions between the urgencies of the short term and the uncertainties of the long term. To be able to better understand the changes linked to the climate and social degradations, and the associated public action methods, to share knowledge and experiences: these are the expectations expressed by elected officials faced with the complexity of territorial issues. STEEP was the first academic partner to join the initiative and sign (through Inria) its charter. We are particularly interested in aspects related to territorial prospective, participation, and risk analysis which are at the heart of the initiative.

The first concrete action launched within l'Atelier des Futurs is concerned with the creation of a “Local Risk Report” for the area (about 500,000 inhabitants), nicknamed RARRe (Rapport annuel sur les risques et la résilience dans la région Grenobloise). STEEP has been involved since the beginning in 2022, to provide scientific and general expertise. The idea of this action is to identify vulnerabilities and especially, systemic links between them, as well as attenuation or preparation measures, in order to inform public policies. The report is planned to appear on an annual basis. The methodology used is inspired by the Davos Economic Forum's annual Global Risks report. Our Systemic Risk Fresco (see Section 10.3.4) was used, among other approaches, to fuel preparatory discussions.

Overview of the 6 families of risks identified in the l'Atelier des Futurs initiative.

In 2023, 44 risks were identified as relevant to the Grenoble area. They are grouped into 6 thematic families (see Figure 10):

• Climate change, pollution, ecosystem collapse and natural or technological disasters
• (Un) availability of ressources and (dys) functioning of networks
• Economic activities
• (In) ability to act, anticipate and transform
• (In) capacity to respond to social needs
• Social cohesion

A questionnaire was created, tested, and then submitted to four panels of stakeholders (elected officials, citizens, business owners, local development councils). The goal was to understand how these risks are perceived by the population, in terms of gravity, likelihood (or being already in existence), possibility to act against them, the effect of actions already in place, the differentiation between local and global impacts of risks, etc.

The first edition of the RARRe was published in 2024. It contains a description and documentation of the above-mentioned risks and an analysis of the responses of the poll carried out based on the above questionnaire. The report was presented at the following occasions:

• A preliminary version was presented on 6 February 2024 to a forum of elected officials of the Grenoble area and directors of territorial agencies or services.
• The official release of the report was made on 10 April 2024, at the occasion of a special event open to the general public.
• We also presented the initiative to Sophie Heading, Global Risks Lead at the World Economic Forum and coordinator of the World Economic Forum's annual Global Risks Reports. According to her feedback, ours is the first local initiative worldwide of this type.
• The RARRe was presented, together with a serious game on risks, in a half-day session at the 2024 Archipel conference in Lyon, 16 april 2024.

10.3.1 Conference-debate series and YouTube-channel “Understanding and Acting”

In view of the global issues described in section 2.1, we initiated in 2016 a series of conference-debates entitled “Understanding and Acting” (Comprendre et Agir) that examines these issues in order to help researchers and citizens to increase their awareness of the various issues at stake in order to initiate relevant individual and collective actions. From now on, the scientific community at large must realize that its duty also lies in helping citizens to better understand these issues. If the fraction of people in society whose privilege is to be paid to think about society’s problems do not seize this opportunity in the critical times we face, who will? Researchers must become more involved in the search of socioeconomic alternatives and help citizens to implement them. The interactions between researchers and citizens have also to be reinvented.

Presentations typically last between 45 to 60 minutes; they are followed by a 45 minute public debate with the audience. The presentations are captured on video and then made accessible on the YouTube channelComprendre et Agir. As of 16 December 2024 the channel has about 14,300 subscribers and reached a total of over 1,135,000 viewings.

In 2024, we had the following conference-debates.

• Valérie d'Acremont (Unisanté, Université de Luasanne), Climate impact on health: what lies ahead and what can be done?, 25 January 2024.

10.3.2 “Faire face, Face cinéma” series

The STEEP team co-organizes with the Design Factory of Université Grenoble Alpes and the PACTE laboratory a series of screenings of documentaries or films dedicated to social-environmental issues called "Faire face, Face cinéma". The screenings are followed by a debate between the director (except in exceptional cases), the organizers and the public. This cycle is supported and animated in particular by Sophie Wahnich (STEEP) and Anne Delaballe (UGA Design Factory). In 2024, the following films and documentaries were screened: La jungle plate (Johan Van der Keuken), Jonas qui aura 25 ans en l’an 2000 (Alain Tanner), V pour vendetta (James McTeigue), Koyaanisqatsi (Godfrey Reggio), and Alphaville (Jean-Luc Godard).

10.3.3 Groupe artistique de recherche scientifique (GAES)

The Hexagone theatre (a French Scène Nationale) based in Meylan, in collaboration with Quai des Savoirs in Toulouse, organizes scientific exploration sessions for artists. These times of discovery are designed as a collective immersion between all participants, artists and scientists alike. The aim is to transmit knowledge on scientific subjects, dispensed by guest scientists, in order to generate exchanges and confrontations between scientific and artistic imaginations, and collective and individual representations. Building on two collaborations in 2021 and 2022, the two partners proposed a new session in 2024, entitled The sciences of prediction, Humankind faced with its contradictions (Les sciences de la prédiction, l’Homme face à ses contradictions) on the sciences of prediction for 2024.

Four STEEP team members (Serge Fenet, Emmanuel Prados, Peter Sturm, and Sophie Wahnich) participated at this 3-day event, together with other scientists from Grenoble and ten invited artists from various artistic disciplines. We gave presentations on our works, on issues of socio-environmental degradations, and on scientific modeling. The event enabled rich exchanges with the artists on their perception of socio-environmental issues, on how they integrate them in their practice, etc.

10.3.4 Productions (articles, videos, podcasts, serious games, ...)

Systemic Risk Fresco.

Systemic risks emerge from interactions within a system in which vulnerabilities are present. If elements of a system are sensitive and sufficiently intertwined, disrupting one or several of them can spread over the whole system, triggering chain reactions and feedback. Systemic thinking is not straightforward 102. Courses in education are often specialized, focusing on one or few themes or objects. Students often go from one subject to the other, without linking them. “All other things being equal” type reasoning then implicitly arises. This kind of reasoning is consequently blind to interactions with – and vulnerabilities to – changes in other elements of a system.

Studying Global Systemic Risks logically implies systemic thinking. Four PhD students of the team (Alexandre Borthomieu, Antonin Berthe, Léon Fauste, and Mathilde Jochaud du Plessix) created a game to vulgarize this kind of thinking. The Global Systemic Risks fresco (Fresque des risques systémiques globaux) is a serious game aimed at broadening the understanding of this aspect. It enables participants to explore interactions within a system and the spreading of disruptions. The game is a visual and spatial representation of the core elements of western societies.

A session takes place in three stages: (i) the construction of the fresco, (ii) the exploration of breakthrough scenarios and (iii) a time of “return to reality”. In the first stage, participants are invited to construct a map of elements they consider important for society; they are guided to first think about primary needs, then means to answer such needs (such as education or a construction sector) and finally, “sectors” allowing to realize these means (energy and materials, finance and geopolitics, “the environment”). Links between all these elements represent dependencies (see figure 11 for a sample outcome).

Photograph showing the outcome produced by participants of one workshop of the Systemic Risk Fresco, after phase I.

In the second stage, the thus established map allows to explore scenarios and questions such as how disruptions in one of the elements are links can spread through the system. The goal is to foster insight in the systemic nature of our socio-ecological system and to encourage participants to think about our needs in a new way, adapted to a degraded environment, and then eventually to create or imagine more resilient alternatives. As these topics are sources of discomfort and strong emotions, a workshop ends with a third stage, to share feedback on what they have just experienced, as well as a time for sharing emotions, which we believe is now essential for any research or knowledge creation around social and environmental issues that affect each person in different ways. Moreover, we believe that this time allows participants to be accompanied in the “return to reality” and to limit the feeling of powerlessness.

The Global Systemic Risks fresco has been employed in various workshops with different types of audience (scientists, students, general public) and we use it now routinely in several courses at university. It has also been demonstrated to members of the public authorities involved in the l'Atelier des Futurs initiative (section 9.4.4), as an input to the preparation of the Local Risk Report for the Grenoble area.

For more details on the fresco, please refer to this report.
