abstract = {This thesis explores the political use of history relating to environmental issues. Anchored in political science, it mobilises environmental history and strategic analysis of environmental management. Its objective is to understand how the reference to the past is used by different actors involved in environmental policies to make their voices heard in argumentative struggles.
The thesis first examines how scientists use history in relation to environmental policies. An exploratory literature review reveals that the use of history is not limited to historians. It is also found in approaches based on political ecology, which aim to build narratives considering the oppressed, and in approaches that examine the functioning of socio-ecological systems through contributions from historical ecology.
This analysis is supplemented by a qualitative survey of French-speaking historians working on environmental issues to explore their relationship with public action. It identifies four typical interaction situations between history and public action, in which historians play different roles: producing knowledge for society, stimulating new thoughts, cooperating to mutually enrich public action and research, and responding to commissions to inform public action.
Scientists in social sciences and ecology are far from the only ones to make the past a political resource.
Engineers, who dominate the process of river management and use, also refer to the past to defend progress and legitimize their actions. An in-depth study of the journal "La Houille Blanche" led to the development of a methodology to identify scattered references to the past in a scientific and technical journal without disconnecting them from their context of enunciation. The analysis of the 220 historically significant articles helped characterize different archetypes of reference to the past in this journal.
The past also serves as a political resource for various coalitions of actors advocating for the recognition of rivers as living ecosystems. Ecologists use the past heuristically as a counterfactual to human action to better anticipate the potential of ecological restoration. Other actors highlight an idealized heritage vision of managed rivers to oppose their restoration.
In response to this political use of the past in argumentative struggles over ecological restoration, an intervention research was conducted in collaboration with the Haut-Rhône Syndicate. Based on a strategic diagnosis of the management situation and the associated stakeholders’ dynamics, the intervention shed light on the various existing public policy narratives about the Rhône. On this basis, a pluralistic narrative was developed and visualized to represent the different voices at play, contributing to a rebalancing of power relations in the territory.
The thesis highlights the tension between the instrumental use of history, employed as a tool for specific objectives, and the historical method, which emphasizes rigorous source critique and narrative plurality.
It asserts that such a method, when strategically mobilized, can become a powerful resource to legitimize actors engaged in ecological restoration.

Anyone can produce political content that can reach a global audience, and social media has become a vital tool for political leaders to convey messages to the electorate. The 2022 Italian election campaign has seen the term “nuclear” debated with two different declinations: on the one hand, regarding nuclear energy for civilian use, and on the other hand, regarding the fear of an escalation of the conflict in Ukraine and the use of atomic weapons. This research aims to analyze the social media debate by exploring multiplatform dynamics to qualitatively identify and analyze the connections between social media platforms that we have termed Bridges, a concept drawn from Transmedia Theory to describe the narrative relationship between platforms. The methodological approach will follow an explanatory sequential design that will rely on digital methods to identify connections between platforms (bridges) and then apply an exploratory qualitative approach to enrich the data and capture the nuances of the debate. As expected, we found polarized positions and fragmentation on both issues of civilian nuclear energy and the atomic conflict narrative. Primary evidence shows bridges spreading affective, defective, and infective content across platforms in a multifaceted social media ecosystem. Affective refers to rhetoric that appeals to people’s feelings. Defective means the discussion that brings attention to hyper-partisan news channels, fake news, and misinformation. Infective means bridges with below-the-radar platforms, niche channels, or pseudo-information channels. They use bridges with mainstream platforms to gain the potential to go viral.

abstract = {Purpose
The global prevalence of social media and its potential to cause polarization are highly debated and impactful. The previous literature often assumes that the ideological bias of any media outlet remains static and exogenous to the polarization process. By studying polarization as a whole from an ecosystem approach, the authors aim to identify policies and strategies that can help mitigate the adverse effects of polarization and promote healthier online discourse.
Design/methodology/approach
To investigate online polarization, the authors perform a systematic review and analysis of approximately 400 research articles to explore the connection between cognitive bias and polarization, examining both causal and correlational evidence. The authors extensively evaluate and integrate existing research related to the correlation between online polarization and crucial factors such as public engagement, selective exposure and political democracy. From doing so, the authors then develop a PolarSphere ecosystem that captures and illustrates the process of online polarization formation.
Findings
The authors' review uncovers a wide range of associations, including ideological cognition, bias, public participation, misinformation and miscommunication, political democracy, echo chambers and selective exposure, heterogeneity and trust. Although the impact of bias on social media polarization depends on specific environments and internal/external conditions, certain variables exhibit strong associations across multiple contexts. The authors use these observations as a basis from which to construct PolarSphere, an ecosystem of bias-based polarization on social media, to theorize the process of polarization formation.
Originality/value
Based on the PolarSphere ecosystem, the authors argue that it is crucial for governments and civil societies to maintain vigilance and invest in further research to gain a deep comprehension of how cognitive bias affects online polarization, which could lead to ways to eliminate polarization.},

The Horizon Europe (HE) Mission “A Soil Deal for Europe” aims to accelerate the transition to sustainable soil and land management and healthy soils through an am-bitious transdisciplinary research and innovation (R&I) programme, largely based on actor engagement, Liv-ing Labs and Lighthouses. The H2020 Soil Mission Support (SMS) project supported the implementation of the HE Mission, and aimed to improve the coordination of R&I on sustainable soil and land management. Through a co-creation process together with actors, SMS collated available knowledge, actors R&I needs and identified R&I gaps that need to be addressed for successful transition towards sustainable soil and land management.
The first step was to identify existing R&I knowledge through a keyword-based analysis of scientific literature published and peer reviewed, related to sustainable soil and land management. The literature analysis ad-dressed the full range of societal challenges, soil health objectives, land use types and knowledge domains necessary to capture the socio-ecological complexity of soil health. Covering some 15,700 scientific articles, this literature analysis represents the current peer reviewed knowledge stock on sustainable soil and land management. A textual analysis using the digital platform CorTexT was undertaken to explore the identified literature and submitted to project consortium internal experts, who analysed and processed the collected information of their respective area of expertise (Annex III). The literature analysis revealed that the societal challenges “reduce soil degradation” and “improve disaster control” have been studied extensively. Con-versely, the societal challenges “mitigate land take” and “increase biodiversity” and the knowledge domains “science-based policy support” and “awareness, training & education” are less discussed. Factsheets present-ing the results of the literature analysis per societal challenge were developed and can be found in Annex VIII. Note that as the key-word based literature search was limited to Scopus-indexed scientific journals, other publishing formats such as conference papers, books, book chapters, non-digitalized articles, grey literature, reports, patents, etc., may be underrepresented or not included in the used data base. The exclusive use of Scopus-indexed scientific articles provided quality insurance of the material through the publication peer-review system. Nonetheless, important documents and knowledge have been incorporated by the consor-tium experts when analysing the collected literature.
The second step was to consult actors through online workshops and surveys in order to gain a practice-oriented ‘real-life’ picture of current knowledge and R&I needs for swift implementation of sustainable soil and land management. This step was seen as complementary of the published and peer-reviewed literature.
Finally, after exploring our stocktaking of R&I from existing knowledge evidenced by literature review and the actor’s knowledge needs identified from actor consultations, we identified R&I gaps. The main knowledge gaps across all Mission Objectives were of socio-economic nature: drivers and causes of land degradation, knowledge management, governance and policies for inciting improved management, and interaction with other sectors are not sufficiently understood. Second, the HE Missions’ focus on improving soil literacy was supported by the literature analysis and by the actor consultation, which both revealed knowledge gaps re-lated to education and capacity building in all land use types and domains affecting soil health: production, consumption, trade, policy and governance. Thirdly, there is a gap in the long-term implementation of a new mode of knowledge co-design, where researchers and practitioners together develop solutions for sustaina-ble soil and land management in a real-world context. The HE Missions’ focus on Living Labs and Lighthouses has the potential to close this gap. Finally, there is a need to define several concepts (e.g. soil health, soil degradation, footprint). Such definitions should be shared and will be a basis to identify relevant indicators and respective thresholds, and to develop guidelines to support monitoring programmes in order to translate knowledge into evidence for decision making.

abstract = {The thesis aims to study both theoretically and empirically the management of ecosystem services by the farmers from the perspective of the economic theory. The concept of ecosystem services is an interdisciplinary concept that refers to "the services that nature offers to human for free". The economic literature has mainly investigated this concept in measuring the value of these services, with few attention to the behavior of agents modifying these services. The thesis is divided into two parts.
In the first part, I study both the supply and the demand for the productive ecosystem services (for example, pollination or biological control) by analyzing the behavior of farmers, considered as potential agroecosystem managers. Inspired by the literature on landscape ecology, I introduce biodiversity indicators that are function of land-use into existing models from
agricultural production economics literature. This reunion provides a unified theoretical model for analyzing farmers' choices regarding the management of productive ecosystem services.
The empirical works consists in estimating all or parts of this theoretical model. My main contribution to the literature is to prove, based on the farmers' observed behavior, that farmers do manage productive ecosystem services. I bring other elements to the literature, notably by providing new insights on the agricultural technology when productive ecosystem services are considered, or by showing that collective management of productive ecosystem services can only rarely arise spontaneously in real landscapes where farmers are heterogeneous.
In the second part, I study the demand for the jointly provided public goods by the farmers’ modification of ecosystem service flows, i.e. I study the specificities of the demand for environmental services provided by farmers (in the sense of Engel et al., 2008). In particular, I study the role of the geographic scale of the demand for the design of agri-environmental policy. Indeed, if local public goods influence the welfare of the agents within a defined geographical
area (e.g., the improvement of water quality by maintaining a wetland upstream of a treatment plant), global public goods can influence the welfare of all agents (e.g., the carbon sequestration into the soil of a wetland). In this part, I apply the framework of several literatures developed in environmental economics (for example, the literature on environmental federalism or on the "distance-decay") to the specificities of the environmental services provided by farmers; in particular, I integrate that the environmental service provided by a farmer affects the supply of multiple public goods in most cases, the demand for these public goods arising at different geographical scales. I contribute to the literature by showing that, although most of the demand for environmental services provided by farmers is captured locally (at the municipal level), some of the demand is captured by larger and farer areas. This has implications for the governance and the design of agri-environmental policies, which I explore through two examples: the reduction of pesticide application and the maintenance of agricultural wetlands.

Dans la première partie, je m’intéresse à l’offre et à la demande de service écosystémique productifs (par exemple, la pollinisation ou le contrôle biologique) en analysant le comportement des agriculteurs, considérés comme de potentiels gestionnaires des agroécosystèmes. Inspiré par la littérature en écologie du paysage, j’introduis des indicateurs de biodiversité dépendant des assolements dans des modèles existants issus de la littérature en économie de la production appliquée à l’agriculture. Ce rapprochement fournit un modèle théorique unifié où l’on peut analyser les choix des agriculteurs vis-à-vis des services écosystémiques productifs. Les travaux empiriques développés par la suite consistent à estimer toute ou partie de ce modèle théorique. Ma principale contribution à la littérature est de prouver, à partir de l’analyse des comportements observés des agriculteurs, que les agriculteurs gèrent consciemment les services écosystémiques productifs. J’apporte d’autres éléments à la littérature, en fournissant notamment des éléments importants sur la technologie agricole lorsque les services écosystémiques productifs sont considérés, ou en montrant que la gestion collective des services écosystémiques productifs ne peut que rarement émergée spontanément
dans des paysages réels où les agriculteurs sont hétérogènes.
Dans la deuxième partie, je m’intéresse à la demande pour les biens publics fournis conjointement par les agriculteurs via la modification des flux de services écosystémiques, i.e. je m’intéresse à la demande pour les services environnementaux fournis par les agriculteurs (au sens de Engel et al., 2008). En particulier, j’étudie le rôle de l’échelle géographique de la demande sur la conception de politique agro-environnementale. En effet, si les biens publics locaux vont influencer le bien-être des agents au sein d’une zone géographique délimitée (e.g. amélioration de la qualité de l’eau en maintenant une zone humide en amont d’une station de traitement), les biens publics globaux peuvent influencer le bien-être de l’ensemble des agents (e.g. séquestration du carbone dans une zone humide).

d’analyse de plusieurs littératures développées en économie de l’environnement (par exemple, la littérature sur le fédéralisme environnemental ou sur le « distance-decay ») aux spécificités des services environnementaux fournis par l’agriculture ; en particulier, le service environnemental fourni par un agriculteur influe le plus souvent sur la fourniture de multiple biens publics, biens publics dont l’échelle de la demande diffèrent.

En effet, si les biens publics locaux vont influencer le bien-être des agents au sein d’une zone géographique délimitée (e.g. amélioration de la qualité de l’eau en maintenant une zone humide en amont d’une station de traitement), les biens publics globaux peuvent influencer le bien-être de l’ensemble des agents (e.g. séquestration du carbone dans une zone humide). Dans cette partie, j’applique les cadres
d’analyse de plusieurs littératures développées en économie de l’environnement (par exemple, la littérature sur le fédéralisme environnemental ou sur le « distance-decay ») aux spécificités des services environnementaux fournis par l’agriculture ; en particulier, le service environnemental fourni par un agriculteur influe le plus souvent sur la fourniture de multiple biens publics, biens publics dont l’échelle de la demande diffèrent. Je contribue à la littérature en montrant que, bien que la plupart de la demande pour les services environnementaux fournis par les agriculteurs soit capturée localement (à l’échelle de la municipalité), une partie de la demande s’exprime à des échelles plus importantes. Cela a des implications pour la gouvernance et la conception des politiques agroenvironnementales, que j’explore à travers deux exemples : la réduction de l’application des pesticides et le maintien des zones humides agricoles.

The concept of ecosystem services is an interdisciplinary concept that refers to "the services that nature offers to human for free". The economic literature has mainly investigated this concept in measuring the value of these services, with few attention to the behavior of agents modifying these services. The thesis is divided into two parts. In the first part, I study both the supply and the demand for the productive ecosystem services (for example, pollination or biological control) by analyzing the behavior of farmers, considered as potential agroecosystem managers. Inspired by the literature on landscape ecology, I introduce biodiversity indicators that are function of land-use into existing models from agricultural production economics literature. This reunion provides a unified theoretical model for analyzing farmers' choices regarding the management of productive ecosystem services. The empirical works consists in estimating all or parts of this theoretical model. My main contribution to the literature is to prove, based on the farmers' observed behavior, that farmers do manage productive ecosystem services. I bring other elements to the literature, notably by providing new insights on the agricultural technology when productive ecosystem services are considered, or by showing that collective management of productive ecosystem services can only rarely arise spontaneously in real landscapes where farmers are heterogeneous. In the second part, I study the demand for the jointly provided public goods by the farmers’ modification of ecosystem service flows, i.e. I study the specificities of the demand for environmental services provided by farmers (in the sense of Engel et al., 2008). In particular, I study the role of the geographic scale of the demand for the design of agri-environmental policy. Indeed, if local public goods influence the welfare of the agents within a defined geographical area (e.g., the improvement of water quality by maintaining a wetland upstream of a treatment plant), global public goods can influence the welfare of all agents (e.g., the carbon sequestration into the soil of a wetland). In this part, I apply the framework of several literatures developed in environmental economics (for example, the literature on environmental federalism or on the "distance-decay") to the specificities of the environmental services provided by farmers; in particular, I integrate that the environmental service provided by a farmer affects the supply of multiple public goods in most cases, the demand for these public goods arising at different geographical scales. I contribute to the literature by showing that, although most of the demand for environmental services provided by farmers is captured locally (at the municipal level), some of the demand is captured by larger and farer areas.

These findings call for the implementation of agricultural research programmes that will consider the socio-agro-ecosystem as a whole and broaden the traditional issues addressed by agricultural sciences. We insist on three main management and operational issues that needs to be overcome if this is to be done: working at the landscape scale, increasing inter-disciplinary collaborations and take uncertainties into account.

abstract = {En 2005, le Millenium Ecosystem Assessment (MEA) a permis de reconnaître l’importance des écosystèmes pour le bien-être humain, ainsi que la diminution d’un certain nombre de services fournis à l’homme par ces mêmes écosystèmes au cours des dernières décennies. L’agriculture est considérée comme responsable de la diminution d’un certain nombre de services, ainsi que de la biodiversité, au profit du seul service d’approvisionnement en nourriture (Carpenter et al., 2009). Elle se trouve donc aujourd’hui plus que jamais confrontée à deux impératifs qui mettent en avant sa multifonctionnalité : garantir la fourniture de biens de consommation (nourriture, bois, eau potable...) et de bénéfices sociaux (e.g. emploi) tout en préservant la capacité des écosystèmes à fournir d’autres services (purification de l’eau, régulation du climat, etc.). EcoServ est un méta-programme de recherche en construction à l’Inra afin qu’y soit développée une recherche inter-disciplinaire sur les services fournis par les écosystèmes continentaux dépendants des activités agricoles et forestières. La présente analyse a été engagée dans le cadre de sa construction, afin de connaître la place des systèmes agricoles dans la littérature sur les services écosystémiques. Ce travail de scientométrie a été guidé par quatre questions principales : quelles sont les disciplines scientifiques impliquées dans cette recherche ? Quels sont les services écosystémiques abordés dans la littérature ? Quels sont les écosystèmes étudiés ? Quelle est la place de l’Inra dans ce paysage ? Le corpus est issu de la base de données bibliographique Web of Science. Il a été construit de manière large afin d’inclure les différents synonymes de la notion de « service écosystémique ». Différentes analyses lexicales ont ensuite été réalisées pour la période postérieure au MEA (2006-2012) à l’aide de la plateforme CorTexT manager de l’Ifris et de R (R Core Team, 2012) : extractions lexicales, catégorisations de termes, calculs de fréquences, cartes de cooccurences. Les termes les plus fréquemment utilisés dans les articles de la période 1975- 2012 sont ecosystem service (39 % des documents indexés), puis ecosystem function (29 %), ecological function (14 %) et environmental service (9 %). Le terme ecosystem function dominera jusqu’en 2007 où il sera supplanté par celui de ecosystem service qui connait une progression exponentielle suite à la publication du MEA (Millenium Ecosystem Assessment, 2003, 2005). Ce concept est particulièrement mobilisé par l’écologie et la biologie de la conservation, d’où il tire son origine. Les trois références les plus citées de ce corpus se situent en écologie (Costanza et al., 1997; Daily, 1997; Hooper et al., 2005). Les sciences agronomiques utilisent plutôt le terme de « services environnementaux », qui met l’accent sur les services rendus par l’homme à l’environnement. La place de l’Institut dans ce corpus étant très faible (1.5 %) malgré les résultats importants obtenus au cours de l’enquête réalisée début 2013 auprès des départements, il est très probable qu’un grand nombre de services soient étudiés à l’Inra sans que les chercheurs se réclament de cette notion. Le service le plus étudié est celui de production agricole. La majorité des services sont étudiés de manière isolée. Lorsqu’ils sont étudiés conjointement, les services concernés sont majoritairement des services qui agissent en synergie. Les services antagonistes sont très peu étudiés conjointement. Par conséquent, lorsque la notion de trade-off apparait dans la littérature, elle est surtout abordée de manière théorique et programmatique. En outre, elle peut concerner différents niveaux et différents objets : il peut s’agir de faire des compromis entre acteurs, ou bien entre désirs et réalité, ou bien encore entre Environnement et Humanité. Si les écosystèmes forestiers et agricoles sont parmi les écosystèmes les plus étudiés, ils le sont principalement dans leur dimension bio-physique, et très peu dans leur dimension sociale. L’idée d’étudier un socio-écosystème dans son ensemble n’est pas encore mise en oeuvre. Les problématiques de gestion des ressources naturelles sont abordées principalement par des méthodologies de l’économie classique : consentement à payer, évaluations contingentes, etc. Elles sont également très liées à un argumentaire en faveur du développement social. Tout ceci amène à penser qu’une grande partie de la littérature sur la gestion des services écosystémiques est avant tout d’ordre programmatique. Cette étude met également en évidence la limite du cadre conceptuel du MEA, limite qui a déjà été pointée à de nombreuses reprises dans la littérature. Ses catégories de service sont en effet de portée limitée pour repérer les services dans la littérature et elles ne permettent pas de détecter les dysservices (entendus ici comme des dysfonctionnements des écosystèmes), qui représentent pourtant une part importante de cette littérature. Cette étude possède également des limites importantes dans la mesure où sa source de données est loin d’être exhaustive et où son travail de catégorisation n’a pas permis de lever certaines ambiguïtés thématiques. Il est en effet souvent difficile de déterminer à partir de la liste de termes s’il s’agit d’un service rendu par les écosystèmes ou d’un service rendu par l’homme (ex. : forest protection). Pour conclure, ces résultats montrent que ce concept a peu été saisi par les sciences agronomiques, quand bien même de nombreuses études traitent des milieux agricoles ; qu’il est beaucoup abordé de manière programmatique et sans considérer le socio-écosystème dans son ensemble. Un grand nombre de travaux effectués à l’échelle du paysage incluent les agro-écosystèmes mais ne sont pas réalisés par les sciences agronomiques. Celles-ci ont intérêt à se placer sur ces « approches paysage » qui gagnent une place de plus en plus importante. Le développement d’une recherche intégrée sur la gestion des écosystèmes anthropisés prend donc tout son sens dans ce contexte, et un travail de sensibilisation important sera à réaliser à l’Inra pour familiariser les chercheurs avec la notion de « service écosystémique ». },
