Vieira, Julien. "Éco-citoyenneté et démocratie environnementale." Thesis, Bordeaux, 2017. http://www.theses.fr/2017BORD0760/document.
Full textGenerated by the impact of human activities on the environment and without ever really being a notion explicitly consecrated by the law, eco-citizenship appears in many legal norms. Ambivalent, this notion suggests both a set of rights of which the public is creditor and a responsibility of the latter with respect to the environment.Starting from this duality of complementary values, the human right to a healthy environment is materialized by the recognition of a right of access to information, of participation in decision-making and access to justice. Thus, the law increasingly provides that the acceptance of decisions depends on the active support of citizens. The development of participatory democracy in the field of planning and sustainable development is indicative of a paradigmatic transformation. In effect, while preserving certain classical modes of public action, the law develops new concepts and organizational schemes that accompany this evolution which has not yet been completed.Whether it is influenced by social phenomena or spontaneously developed, environmental law gradually reveals the role of the citizen in the form of recourse to the courtroom but also by the evolution of the non-contentious administrative procedure. Centrally founded on the study of French environmental law as well as on several comparative incursions, this thesis is also based on sociology, philosophy or political and administrative sciences. This academic work intends to address the way in which the law takes into account the imperative of eco-citizen participation
Niang, Pathé Marame. "Les processus participatifs dans la gestion des écosystèmes en Afrique de l'Ouest : une contribution à la démocratie environnementale." Thesis, La Rochelle, 2015. http://www.theses.fr/2015LAROD003/document.
Full textThe participative processes basing on the principles of information and participation regarding environment contribute to the environmental democracy in Africa the West. This contribution is made beyond the implementation of these principles in the management of the ecosystems, by the research for an environmental social justice and the attempt to implement (operate) the principles of good governance in the service of the management of the ecosystems and the respect for human rights in the field of the environment. However, so that the participative processes make a better contribution to the environmental democracy in western Africa, it is necessary that the legal framework of the participation of the public is clarified. This legal framework concerns as well the access to the information, the procedures of participation of the public in the decision-making and in the management regarding environment, but especially to offer the possibility to the public to be listened by the justice or by of other one methods of payment of the disputes regarding environment and regarding management of the ecosystems
Tissiere, Laurie. "Espaces, temps et acteurs de la démocratie environnementale : analyse à partir d’une géoprospective des pêches maritimes du golfe de Gascogne." Thesis, Nantes, 2018. http://www.theses.fr/2018NANT2059/document.
Full textParticipation is normalizing in management and research practices, especially in environmental management and research. This trend founded this research in geography. Geoprospective is a way to collectively create spatial and long-term scenarios thanks to a large use of simulation tools. Moreover, it is considered as a mean to enhance environmental democracy. In this thesis, geoprospective is also considered as a mean to explore the contribution of space and time to the environmental democracy, in terms of power, knowledge, interactions between actors and models and social and political impacts of scenarios process. In order to test this hypothesis and for several other reasons (originality of spatial and temporal dimensions, centrality of power, hierarchy of knowledge), a geoprospective exercise has been applied to the fisheries of the Bay of Biscay.This exercise was based on a combination of participatory interviews and modeling. The materials and reflexivity analysis have shown that spatial and temporal dimensions of environmental democracy are multiwfaced. First, space and time lie in the transmission of knowledge. Then, space and time lie in the appropriation of models. In the end, space and time lie in actors narratives, play and imaginaries
Lejeune, Caroline. "En quête de justice écologique : théorie politique environnementale et mobilisations sociales." Thesis, Lille 2, 2015. http://www.theses.fr/2015LIL20022.
Full textThis work aims at analysing the theoretical evolution of social justice when it is progressively confronted to environmental limits. It is based on the study of the social and institutional movements that arose around an urban planning project – the Union Zone – in the metropolis of Lille, Northern France. These social movements were at first concentrating their claims on issues far from ecologicalconcerns. But a slow evolution of their claims took place when they were confronted to a project of “exemplary eco-district” (2006-2022). This work will focus on the shift from social claims (based on distributive justice and political acknowledgement) to ecological claims (where social justice is confronted to environmental limits). Drawing on an analysis of the transformation of discourses, of the participation procedures, and of the evolution of the theoretical frames used by the social movements, we offer an insight on the conditions of transformation of pluralist representative democracy. This analysis of the issues and purposes of ecological justice aims at reconsidering the way environmentallimits could be incorporated into the participative practices of democracies. Drawing on the field of green political theory, this work also aims at showing that ecological justice lays on an ecocentrist view of justice that could contribute to question the theory of democracy in the light of existentialinterdependences connecting the ecological and the social spheres
Samson, David. "La crise environnementale : critique historique et philosophique des notions de conscience écologique et de rationalité instrumentale." Thesis, Paris, EHESS, 2019. http://www.theses.fr/2019EHES0072.
Full textThis theoretical and empirical work aims to question two concepts which structure environmental studies and philosophy of technology: “ecological consciousness” (or “environmental awareness”) and “instrumental rationality”. In itself, it is also a reflexion on the relations between philosophy and social sciences and on transdisciplinarity, often considered as a central trait of “postmodernity” and of the “rule of technology”. In order to do so, il uses various sources (legal, political, mediatics and academics) and several experiences of participant observation to participative democracy apparatuses (in particular at the French High Council of Biotechnologies).By furthering the criticism of the “reflexive Modernity” paradigm, the first part analyzes the problematization of the “environment” in France (1870-1945) and in Germany (1900-1945). The genealogy of environmental governability and of expertise leads to question the opposition between “anthropocentrism” and “biocentrism” and to reconceptualize the idea of a sudden “environmental awareness”. We will rather conceptualize the “environment” as a composite, variable, heterogene and potentially contradictory agencement.This will also lead us to substitue to the conceptual triangle “Technology-Environment-Modernity” a four terms diamond, “Technology-Environment-Modernity-Nazism”. Notwithstanding the role of technology in the Holocaust and Heidegger’s particular status, the analysis of nazism leads us to question the equivocity of calls to live “in harmony with nature” and to “control technology” as well as the idea that we could identify an “occidental relation to nature”.In our second part, the commentary of Heidegger and of the Frankfurt School allows us to analyze the notion of “instrumental rationality” and the idea that anthrpocentrism would be the cause of the environmental crisis. Calling on history of philosophy as well as on the problematization of historical and legal cases, we will henceforth analyze common problems to the critique of technology and environmental ethics, in particular the notions of an “ecological conversion” and of the indermination of technology . We will in particular treat of the project of a technical and environmental democracy and of its limits. The main aim of this work is henceforth to think differently the environment, technology and sciences, but also law and politics which aims to regulate them and thus confront the environmental crisis
Larroque, Claire. "La gestion des déchets par les sociétés industrielles au regard de la problématique environnementale : enjeux éthiques, sociaux et politiques." Thesis, Paris 1, 2017. http://www.theses.fr/2017PA01H229.
Full textThis thesis aims at examining the ethical, social and political issues raised by waste management of industrialized societies. Philosophical analyses of waste management generally adopt a symbolic approach that tends, in one hand, to ignore political and social issues and, on the other hand, to disregard the human-nature relation since environmental issues of waste management are limited to technical sphere. Yet, I suggest that this dual approach must be criticized and question the idea that technicians should deal with the waste treatment while philosophers (or sociologists) should only considerer the symbolic significance. This work argues that waste management of industrialized societies is not only a technical issue since its continuously in relation with the social sphere and among other things raises issues of justice. In this regard, I support that the environmental issue caused by waste management can only be grasped if we assume a conception of nature as community: when wastes affect (unevenly) the environment in which people live, wastes also have an impact on the populations because people nurture interdependent relationship with their environment. Once this has been established, I demonstrate that a cultural vision of environmental inequalities should be defended in order to identify and determine normative principles of waste justice
Jacob, Théo. "De la conservation en Amazonie : norme environnementale et démocratie territoriale à l’heure du « Faire mieux avec moins ». La Guyane française et l'État brésilien de l'Amapá entre tensions et normalisations." Thesis, Paris Sciences et Lettres (ComUE), 2018. http://www.theses.fr/2018PSLEH074/document.
Full textIn Amazonia, nature conservation is oriented towards governing men. In the name of biodiversity, marginalized population are being monitored on peripheral territories. Initially designed as tools of restriction, protected areas now go together with decentralisation. Their new goals for local democracy and economic development participate of a globalized evolution of public administration, from « sovereignty » to « governmentality». By comparing French and Brazilian processes of State reforms, this thesis first explores how environmental norm, by imparting a scientific power to the diversity and subsidiarity principles, is prompting a liberal reshuffle in states that were historically centralized. Updating a « self government » myth, the Environment is shaping a new « social contract », in the form of a territorialized moral governance project that strives to counterbalance inequalities through community federation. Secondly, an historical study of large protected areas shows how conservation complements state redeployment. In Amapá and French Guyana, it comes after sovereign function strategies maintained on a distant Amazonia, switching between paternalistic attitude and delegation of authority to local elite groups. On these « abnormal » territories, where natural resources articulate strong financial interests, conservation institutions are trying to reconcile different legitimacies. In bringing together local communities, public officials and economic players, administrators organise spaces of state governance that go along with regional autonomy. These concertation places are aiming to restrain the development of social and political gaps, in creating new mobilities on the territories. Finally, a compared ethnography of role plays, enlistment strategies, and emerging conflicts, shows the securitarian origin of these mechanisms for these central States. Environmental protection justifies a frugal type of governance, by multiplying counter powers and surveillance entrenchments between stakeholders of a common space. When inciting the emergence of a new « civil society » in barely administered back lands, this creates new rivalries and spreads managing rationale of responsibility. If an analysis of subjectification reveals that « adaptable coercion » compel political and economical powers to adjust strategies, it also demonstrates its difficulty to satisfy « state request » originating from local population. Comparability of Guyanese and Amapaense experiences therefore questions the evolution of the « French model », which is each time more dependant of a « proactive citizenship », that only the most privileged parts of the territories can see emerge
Na Amazônia, a conservação da natureza contribui para governar os homens : em nome da biodiversidade, as populações marginalizadas são gerenciadas em territórios periféricos. Inicialmente concebidas enquanto ferramentas de proibição, as áreas protegidas acompanham hoje o processo de descentralização. As novas missões de democracia local e de desenvolvimento econômico participam de uma mesma evolução da administração pública, que vai de uma lógica de “soberania” ao registro da “governamentalidade”.Pela comparação franco-brasileira dos processos de reforma do Estado, a tese mostra em um primeiro momento como a norma ambiental, conferindo força científica aos princípios de diversidade e subsidiariedade, incita a “recomposição liberal” em Estados historicamente centralizados. Atualizando um mito de self-government, o meio ambiente delineia um novo “contrato social” : um projeto de governança moral, territorializada, contrabalançando as desigualdades pela federação comunitária. Num secundo tempo, o estudo histórico de grandes áreas protegidas mostra como a conservação vem apoiando a reforma do Estado. No Amapá, como na Guiana francesa, ela sucede às estratégias de manutenção da soberania sobre uma Amazônia afastada, alternando a tutela paternalista e sua delegação às elites locais. Nesses territórios « anormais », onde as riquezas naturais estruturam fortes interesses econômicos, as instituições de conservação da biodiversidade tentam reconciliar diferentes legitimidades. Reunindo comunidades locais, representantes públicos e atores econômicos, seus gestores animam espaços de governança que acompanham o empoderamento regional. Esses espaços tentam regular o desenvolvimento das disparidades sociais e políticas, estimulando novas mobilidades nos territórios. Enfim, a etnografia comparada dos jogos de atores, das técnicas de governo e dos conflitos emergentes, revela a natureza securitária desses dispositivos colocados em cena pelos Estados centrais. A proteção do meio ambiente justifica um sistema de governo frugal, multiplicando os contrapoderes e o encaixe das vigilâncias entre os atores de um mesmo espaço. Estimulando a emergência de uma “sociedade civil” em áreas sub-administradas, cria-se novas concorrências e difunde-se uma racionalidade gerencial de responsabilização. Se a análise das subjetivações mostra que essas “coerções flexíveis” obrigam as forças político-econômicas a adaptar suas estratégias, revela também a dificuldade desses dispositivos em satisfazer as demandas da população. A comparabilidade das experiências guianensas e amapaenses questiona então a evolução do “modelo Francês”, cada vez mais dependente de uma “cidadania proativa”, que só as partes mais privilegiadas dos territórios veem emergir

Full textThe consequences of our modes of production and consumptions on the global environment have been recognized and analyzed for many decades: climate change, biodiversity collapse, tensions on numerous strategic resources etc. Our work follows a line of thought aiming at developing other indicators of wealth, alternative to the Growth Domestic Product. In particular, in a perspective of strong sustainability, we focus on biophysical (non-monetary) accounting, with the objective of pinpointing environmental externalities. A large part of existing research in this domain being targeted towards national levels, we rather focus on subnational scales, with on strong emphasis on French regions. With decentralization policies, these territories are indeed given increasing jurisdiction and also benefit from greater margins of action than national or international levels to implement a transition to sustainability. After studying the characteristic of existing tools used in the fields of ecological economics and industrial ecology, such as the Ecological Footprint, Material Flow Analysis (MFA), Life Cycle Assessment or Input-Output Analysis, we focus on supply chains that we analyze through the quantities of materials they mobilize during the production, transformation, transport and consumption steps. The method developed, the Supply-Chain MFA, provides coherent flow diagrams at the national scale, but also in every region and, when data allow it, at infra-regional levels. These diagrams are based on a systematic reconciliation process of available data. We assess the precision of input data, which allows to provide confidence interval on results, and in turn, to put the light on lacks of knowledge. In particular, we provide a detailed uncertainty assessment of the French domestic road freight survey (TRM), a crucial piece of the Supply-Chain MFA. By doing so, we show that undertaking the study on a period of several years not only solves the issue of stocks but also significantly reduces uncertainties on trade flows between regions. We then adapt the Absorbing Markov Chains framework to trace flows to their final destination and to allocate environmental pressures occurring all along the supply chain. For instance, in the case of cereals, we study energy consumption, greenhouse gas emissions, the blue water footprint, land use and the use of pesticides. Material flows can also be coupled with economic modeling in order to forecast how they will likely respond to certain policies. In collaboration with the laboratory of forest economics (LEF), we thusly provide the first attempt of representing the whole French forest-wood supply-chain, and we analyze the impact of a set of policies on both the economy and physical flows. Finally, we show the opportunities of linking these supply-chain results with qualitative methods unfold in the domain of territorial ecology, stakeholder analysis in particular. We situate our work in the normative framework of deliberative democracy and are therefore interested in the contributions of biophysical accounting to public decision processes that include diverse stakeholders. We propose an overview of decision modes, key steps of decision-aiding, multicriteria methods, but also of the various forms taken by citizen participation. We eventually design a deliberation-aiding method, based on elicitation of each stakeholder’s satisfaction and regret regarding a given future. It aims at organizing the discussion on an apparent consensus mode, which by nature facilitates the respect of minorities. Finally, based on the main criticisms addressed to quantification, we propose in conclusion thoughts on the conditions that could put biophysical accounting at the service of democratic emancipation

Full textDeveloped by environmental economists during the 1990s, Payments for Environmental Services (PES) are market mechanisms, promised as being innovative for natural resource conservation. This theoretical construction, circulating within academic and international political spheres, coexists in practice with a « variety of PES ». Presented as an ideal example of PES, the Programme for Payment for Environmental Services (PPES) of Costa Rica, introduced in 1996, is however very far from the theoretical model of environmental economics. In fact, tico PES are incentives, financed and put into place largely by the state. They subsidize not only private forest conservation but also wood production. This work « reinserts » political variables, too often omitted in the environmental economic literature, in order to explain the specificities of the Costa Rican PES. By looking at the impacts of the internationalization of public action on national and local level, we identify two variables which help to comprehend the « translation» process of these international tools : government by coalitions and formal and informal rules of the national political regime. This study questions the democratization and the eclipse of the state usually associated with environmental politics. It shows that the Costa Rican political regime structures and authorizes a game by coalitions, which is rather closed and «discrete » (Culpepper, 2011), distant from « politics » and structured around the stakes linked with wood production. This game tends to take over the construction of PES mechanisms, in order to appropriate the financial flows which stem from the state’s redistribution and international cooperation. This game engenders an enclave of « limited pluralism » (Linz, 1964 ; Hermet, 2004) confined within the democratic Costa Rican regime

Full textDuring the 2000’s decade, two social movements, the décroissance movement in France and Transition Towns in the United- Kingdom, have contributed, both in parallel, to a renewal of the green political landscape. This thesis is an international comparative analysis of these two movements, which were first distinct, then progressively overlapped as they evolved to become international. This research will focus in particular on the catastrophist dimension of these two movements, understood as a form of political thought based on the anticipation of major ecological shifts (peak oil, climatechange, ecosystems collapse, etc.) that would put an end to the modern version of the democratic project. Far from being an intellectual framework only, catastrophism also gives rise to experimental deliberative practices that put into question the hypothesis of continuity that generally pervades theories of democracy.The analysis of these two movements aims at proposing new material to provide for a theoretical reflection on the intellectual tools that political science uses to investigate the ecological embeddedness of political communities. Dwelling on the pioneer work of green political theory, we will suggest that a théorie politique environnementale could contribute to reconsider theories of democracy, with an invitation for them to fit within the framework of the global ecological disruption

Full textThe Environmental Impact Assessment has proven itself as a tool for prevention of environmental damage and as a tool for public information and participatory democracy. However, experience gained in the implementation of the Directive EIA of 27 June 1985 and of the Espoo Convention of 25 February 1991, has quickly highlighted that in many cases, environmental assessment intervened too late in the decision making process, at a stage where the possibilities for significant changes are limited, so that it is possible to doubt the existence of an impartial administrative authorization taking full account of any impact assessment on the environment and public comments since the responsible political authorities have already decided clearly in favor of a project. You had to go further, because it is in fact at the level of strategic options that structural choices, often irreversible, are carried out, in other words at the level of documents such as town and country planning, to mention only the most current. That's why were adopted Directive SEA of 27 June 2001 on the assessment of certain plans and programs on the environment, as well as the Kiev Protocol of May 2003 on "Strategic Environmental Assessment", two very ambitious texts concerning a large pan of decision making in the public sector. It is also, only after having carefully determined the scope of the procedure and many difficulties it raises, it will then be possible to appreciate, in a more circumspect way, the "strategic" contributions or legal perspectives of the new requirement, the French ten years experience and a groping transposition, revealing in this regard that the path could still be long to go before full compliance with European and UN constraints

Full textCette thèse examine les questions éthiques, sociales et politiques posées par la gestion des déchets mise en place par les sociétés industrielles. La réflexion prend son point de départ dans le constat qu’en philosophie l’analyse de la gestion des déchets se limite à une approche symbolique des rapports que nous entretenons avec eux. Il s’agit de montrer qu’une telle approche occulte l’arrière-plan politique et social du problème et qu’elle ne fait pas de la gestion des déchets l’objet d’un questionnement sur le rapport entre l’homme et la nature, reléguant l’enjeu environnemental posé par les déchets au domaine technique. Ce travail propose de dépasser la logique dualiste selon laquelle il reviendrait aux techniciens de prendre en charge le traitement physique des déchets et aux philosophes de s’occuper de l’examen d’une signification symbolique (intrasociale). Il s’agit de démontrer que loin d’être circonscrite à la sphère technico-économique, la gestion des déchets par les sociétés industrielles est en interaction permanente avec le monde social et soulève des problèmes de justice. Dans cette perspective, le problème environnemental soulevé par les déchets ne peut être saisi que si l’on adopte une conception de la nature comme communauté : les déchets en atteignant (de façon inégale) l'environnement des populations affectent également celles-ci parce qu'elles entretiennent avec lui une relation d’interdépendance. Afin de déterminer les principes normatifs d’une justice détritique et de penser une juste gestion des déchets, la thèse soutient alors une conception culturelle des inégalités environnementales.

Tchoba, Charles. "Culture, développement durable et démocratie participative : l'exemple des ONG environnementales gabonaises." Pau, 2005. http://www.theses.fr/2005PAUU1005.
Full textAt present, the sustainable development is one of the topics that worry more the nongovernmental organizations (NGO's) on the international scene. How could NGO's constitute a strong vector of popular mobilization and promotion of the sustainable development through the projects that they implement ? Which are the links between sustainable development, culture and participative democracy ? The objective of this thesis is to wonder about the role of culture in sustainable development and participative democracy, related to the environmental protection. After a development on the concept of culture, the thesis shows that the little of interest granted to this concept constitutes an important lack in the approach of sustainable development and participation. Indeed, the culture is mediating the relations that the subject maintains with its environment. Such a lack explains the difficulties encountered by the actors who work in favour of the sustainable development and the conservation of biodiversity. It is what we show in the precise field of the forest starting from an empirical case : the Gabonese environmental NGO's. Ultimately, this thesis suggests not ignoring the topic competence, i. E. The capacity of subject to know how to function in space. Within the framework of sustainable forest management, it thus appears necessary to develop the aforementioned competence in thought and action, by holding account of the various representations of nature as well as deep aspirations of the topic actors
Breteau, Lucien. "Développement durable et mutations de l'Administration territoriale." Thesis, Lyon, 2018. http://www.theses.fr/2018LYSE2033.
Full textDespite its numerous uses in many juridical orders : sustainable development has differents meanings. On one hand, it means that the environment needs to be protected in order to guarantee rights of future generations. On the other hand, sustainable development is equally defined as the conciliation between environmental policies, economical development and social progress. Territorial restructuring drafts are confronted at this polysemous concept.In spite of this difficulty, sustainable development is consolidated by french public law in his finality as far as its means. About that, standstill principle and environmental responsability enhance this theory.Other principles contibute to sustainable development realization. Environmental democracy takes an independence compared to the classical reprensentative democracy’s concept. In reciprocity, territorial restructuring keeps an influence on public policies about this constitutionnalized notion since the 2005’s Environnemental Carta

Full textThe study of Public Participation in Environmental Decision-making demonstrates that participation contributes to Modern state's mutation. International, europeans and french laws offer from now on various perspectives for the public to influence the construction of environmental decisions. If it does not change the nature of the french notion of general interest, it surely modifies the way to elaborate such interest. The study emphasizes more precisely the role of individuals and groups of interest in this new procedural democracy. It underlines furthermore the conditions in which public participation can really satisfy its two main objectives, the legitimization of public action and the improvement of the content of environmental decisions

Full textThe Ebola hemorrhagic viral fever is an emerging infectious disease that occurs in the form of rapid outbreaks. Since its first event in 1976, several studies have given rises to various speculations about the nature of its natural reservoir of the virus, which has recently been linked to three species of fruit bats: Hypsignathus monstrosus, Epomops franqueti and Myonycteris torquata. However, although the reservoir seems now to be known, the infection transmission chain and the natural conditions of the epidemics emergence remain none elucidated. In addition, until now, we do not have a vaccine against the Ebola virus although considerable progresses have been accomplished in this way by researchers. Between 1994 and 2005, eight Ebola epidemics occurred in Gabon and Congo. Three main observations permitted us to consider that the Ebola fever is a phenomenon linked to environmental conditions : the virus caused epidemics in the same region “Northeastern of Gabon - West basin of Congo”; the epidemics showed a certain seasonality pattern, since it often occurred during the dry to rainy season transition period ; human epidemics occurred simultaneously or after great mortalities affected populations of gorillas and chimpanzees. Even though an effective treatment or a vaccine would be available in a very close future, prediction, prevention and rapid control of epidemics would remain a major priority in public health. With this in mind, a study was considered about the possible interactions between “the environmental conditions” and “the epidemics emergence”, using a geographical approach with remote sensing and GIS tools. This work has consisted on studying the spatial and temporal dynamics of environmental parameters, as for example, topography, hydrology, vegetation, and so on, in the epidemics area. This study has two main objectives: to characterize the natural environment of the epidemics area and to identify environmental indicators that may be linked to the ecological processes leading to the epidemics. It was shown that the epidemics region has generally a flat topography and it is located in high and pluvial lands, presenting a dense hydrographic network. This results on a very wet environment marked by dense vegetation with specific flora. The ecosystem is therefore subservient to high humidity conditions. In this context, the "environment humidity" is then playing a central role in the ecosystem functioning. This role consists on modulating crucial interactions between humans, forest and animals, which constitute the essential basis of the exchanges involved in the natural virus life cycle. We therefore conclude that "environment humidity" is a propriety closely linked to ecological processes that are at the origin of Ebola fever outbreaks in Gabon and Congo. Finally, the results of this study offer positive perspectives on the use of satellite imagery in determining a threshold of risk of epidemics. The temporal evolution of moisture in environment can be followed, firstly, through changes in the vegetation index NDVI and, secondly, through changes in the radar backscattering. Any value exceeding the critical threshold defined would constitute a warning signal from which the health authorities of the concerned countries could implement awareness and prevention actions

Full textMonkeypox (MPX) is a rare severe viral zoonotic smallpox-like disease affecting animals and humans living within tropical rain forest of West and Central Africa. The Democratic Republic of Congo (DRC) reports nearly 85 % of all known human cases and this country experienced several outbreaks over the past few years.After 30 years of cessation of vaccination campaigns against smallpox, the majority of authors agree that a significant rise of MPX cases is observed in several tropical regions including the DRC and this becomes a real problem for public health. However, MPX remains a rarely studied disease and the factors related to its transmission and its spatial distribution remain poorly understood.This research was conducted to contribute building a MPX prevalence estimator in scale of DRC and to understand the determinants of its spatial and temporal distribution. First, a score was constructed to assess the level of adequacy between reported morbidity generated by Integrated Disease Surveillance and Response (IDSR) data in DRC and real morbidity. Then, a study of the search for MPX spatial and temporal clusters in the DRC at the HZ scale was carried out using the SaTScan® software. Finally, a hierarchical Bayesian model was developed to explore the association between MPX cases and specific environmental risk factors with R®.A simple and pragmatic score was elaborated to quantify the validity of data generated by the IDSR in the DRC. The study of MPX spatial aggregates research showed an over-incidence of reported cases in the two traditional foci of Sankuru and Tshuapa districts but with an extension in some surrounding districts over the years making these areas epicenter of the circulation of the MPX pathogen in the central basin of Congo. The temporal analysis highlighted a seasonal trend with an increase in MPX cases during the dry season. The developed model suggests that several major physical environment factors alone are positively associated with the disease incidence but are not sufficient to fully understand the emergence and persistence of MPX outbreaks in the DRC. Therefore, it is necessary to take into account socio-economic as well as anthropological factors, which will support understanding the people relationships with their environment as the driver of risk exposure.Our study allowed targeting high-risk areas and periods that could be prioritized for prevention and interventions to control monkeypox outbreaks in DRC and other concerned African countries.Key words: Monkeypox, Democratic Republic of Congo, adequacy score, Integrated Disease Surveillance and Response, reported morbidity, real morbidity, SaTScan, spatio-temporal clusters, Bayesian model, and environmental factors

Full textA l’aide des techniques modernes de caractérisation (physico–chimique, minéralogique et morphologique), nous sommes arrivés à cibler, à adapter et à justifier l’utilisation d’une technique de valorisation des matières minérales existantes. Les minéraux utiles contenus dans les rejets UZK ont été sulfatés par digestion et sélectivement mis en solution après un grillage. La sulfatation s’est avérée l’étape déterminante du procédé et un intérêt particulier a été focalisé sur cette étape en réalisant une étude cinétique approfondie.
Les données et informations récoltées tout le long de cette recherche nous ont permis de réaliser une simulation du procédé par le logiciel ASPEN PLUS. Ce qui a permis de faire une ébauche d’un schéma de traitement industriel. Ce dernier s’est avéré souple vis-à-vis de l’utilisation d’autres matières comme les calcines des concentrés sulfurés cuivre-zinc.
Residues from the Kolwezi Zinc Plant (Usines à Zinc de Kolwezi UZK) essentially contain zinc in a refractory (ferrite) form, which is difficult to recover by conventional hydrometallurgical methods. « Heavy» metals are also present that make them hazardous towards the environment in which they are currently stored. Most of these metals are valuable; thus, the UZK residues are a real secondary deposit. It is therefore imperative to develop an appropriate method of treatment, hence the theme of the present thesis: « Recovery study of values metals from Kolwezi Zinc Plant residues, DRC ».
Using modern techniques of characterization (physical and chemical, mineralogical and morphological), we focused, adapted and justified the use of a technique for efficient recovery of the existing valuable minerals. The minerals contained in UZK residues have been sulphated by digestion and thereafter selectively dissolved after roasting. Sulphatation proved to be the decisive step of the process and a particular attention has been given to this step by performing a detailed kinetic study.
The data and information collected throughout this research allowed a simulation of the developed method by using the « Aspen Plus » software. This allowed us to propose a draft scheme of industrial processing. The latter proved flexible towards the use of other materials such as calcines of copper-zinc sulphide concentrates.

Full textOur investigation is a study of the process of spatial creation and uncontrolled development of the city of Kinshasa, in the hills of the West and of the Southwest. This research has attempted to analyze the challenges and opportunities for planning and urban development. We focused on the issue of the invasion of open spaces and interstices to cables in planned cities and its environmental and socio-economic consequences. Based on our analysis, we concluded that urban policies suffer from a lack of coherent organizing space. Management of urbanization includes controlling land which could constrain spatial expansion, characterized by the paradigm of ecological marginalization. This is one of the main ways to tame urban growth and give neighborhoods as well as the city of Kinshasa the desired physiognomy

Full textThis dissertation examines how environmental conflicts, during Franco's dictatorship in Aragon (1939-1979), became a component of social and political struggle against the regime. By combining local, regional and national data sources, we discovered how legal protests against industrial pollution from the early 1950s forced the regime to regulate industrial activities and expertise. Large dam projects and weak regulation during the 1960s transformed certain conflicts into radical social movements. In the early 1970s, the regime had to face discontented local authorities and an increasingly critical public opinion regarding environmental projects. The most problematic environmental projects included the first Ebro River Transfer, the large Pyrénées dams, the nuclear power plant settlements and industrial pollution. Since 1972 to free municipal elections in 1979, the anti-Franco opposition, every part of neighbourhoods affected, the new intellectuals and the new environmentalist associations joint subversive and legal actions to defend environmental quality. They mobilized urban and rural society against an "unfair distribution of environmental sacrifice", introducing "the right to the environment" within the democratization agenda. Since then, the State had to create new methods of control in order to respond to the emerging discontent regarding environment issues, while also catering to the special interests of the industrial manufacturers and lobbyists. Subrogation or subordination of these environmental claims, regarding national political parties and trade unions, emerged after the parliamentary elections of 1977 and generated the political ecology in Spain

Full textPour ce faire, une parcelle d’échantillonnage de 25 ha (500m 500m) a été délimitée dans le bloc sud de la RFY constitué d’une végétation ligneuse mixte et semi-décidue. Un inventaire forestier a permis d’analyser la composition floristique et structurale de la zone. Trois techniques (ou modèles statistiques) relevant de l’écologie spatiale pour l’analyse de la structure horizontale des espèces ont été utilisées :la méthode du voisin le plus proche de Clark & Evans (1954), la méthode d’échantillonnage aléatoire de Hines & Hines (1979), ces deux méthodes reposant sur une analyse à échelle unique de la parcelle d’étude, et la méthode de Ripley (1977) permettant non seulement une analyse multi-échelle mais aussi l’étude des relations intra et interspécifiques. Concernant ce point précis, les arbres ont été catégorisés en trois stades de développement sur la base de leurs diamètres (les jeunes, les immatures et les adultes). Une analyse comparative et théorique des trois méthodes a été effectuée.
Un total de 169 espèces appartenant à 36 familles dont 114 genres ont été identifiées, et la famille des Fabaceae dont la majorité des espèces appartiennent à la sous famille des Caesalpinioideae est apparue prépondérante. Trois espèces se sont révélées les plus abondantes et les plus représentatives du peuplement, et ont pour cette raison fait l’objet de toutes les analyses :Gilbertiodendron dewevrei J. Léonard (De Wild), Scorodophloeus zenkeri Harms et Uapaca guineensis Mull. Arg. Elles ont toutes les trois montré une structure agrégée, et cela à toutes les échelles d’analyse. Les agrégats observés présentent un rayon d’environ 25 m de distance. L’analyse en fonction du diamètre a indiqué une structure agrégée pour les plus petits diamètres et régulière pour les plus grands, et que l’agrégation diminue avec le diamètre. Les résultats montrent également que les structures spatiales observées dépendent de l’échelle d’analyse considérée et de la méthode utilisée. La méthode de Clark & Evans est sensible à la variation de l’étendue. À cet égard, l’échantillonnage aléatoire de Hines & Hines est apparu plus adaptée que celui de Clark & Evans. Les fonctions de Ripley et dérivées sont des outils efficaces et apportent plus d’information. Les analyses ont montré des associations positives entre G. dewevrei et S. zenkeri, ainsi qu’entre G. dewevrei et U. guineensis. Par contre, une indépendance a été constatée entre S. zenkeri et U. guineensis. Il apparaît également que les jeunes sont associés positivement aux adultes supposés reproducteurs, et que les immatures sont indépendants par rapport aux adultes. La dispersion faible ou limitée des graines à proximité des arbres parents en est le principal facteur endogène responsable. Ce facteur explique également les associations positives entre les jeunes et les adultes de la même espèce. La compétition entre des individus pour les besoins en espace, en lumière ou en nutriments dans le sol, explique la structure régulière observée ainsi que l’indépendance des immatures envers les adultes. La dispersion limitée n’est cependant pas le seul facteur explicatif de l’agrégation spatiale des arbres, d’autres facteurs tels que l’hétérogénéité environnementale (sol, topographie,…) ou la perturbation sont vraisemblablement aussi impliqués. La perturbation anthropique ou naturelle est un processus écologique qui devrait avoir joué un rôle déterminant dans l’organisation spatiale des communautés de la forêt. Combinée au phénomène de masting, aux effets de Janzen-Connell et aux ectomycorhizes, elle est très probablement à la base des structures spatiales et des relations spatiales observées entre les espèces de la RFY. / Tropical forests contain tree-stands with management and planning requires knowledge of their spatial organization and dynamics. Analyses of the spatial structure of tree species can be used in natural forests to identify the underlying mechanisms that structure of forest stands to improve the understanding of the relationships between species. This study was conducted in the Yoko Forest Reserve (YFR) around Kisangani in eastern DR Congo (DRC). It is to analyze the horizontal spatial structure of the most abundant species and to try to identify, on a local scale, factors and / or potentially explicative ecological processes to draw valuable lessons for the management of forest areas nearby Kisangani.
To do this, a sample plot of 25 ha (500m x 500m) was delineated in the southern block of the YFR consists of a mixed woody vegetation and semi-deciduous. A forest inventory was used to analyze the floristic and structural composition of the area. Three techniques (or statistical models) under spatial ecology for the analysis of the horizontal structure of the species were used: the nearest neighbor method of Clark & Evans (1954), the random sampling method Hines & Hines (1979), these two methods based on a single scale analysis of the study plot, and the method of Ripley (1977) allows not only a multi-scale analysis, but also the study of intra- and inter-relationships. Regarding this point, the trees were categorized into three stages of development on the basis of their diameters (young, immature and adult). A comparative and theoretical analysis of the three methods was performed.
A total of 169 species belonging to 36 families with 114 genera have been identified and the family Fabaceae which the majority of species belong to the subfamily Caesalpinioideae appeared decisive. Three species have proved the most abundant and the most representative of the stand, and for this reason the subject of all analyzes Gilbertiodendron dewevrei J. Léonard (De Wild) Scorodophloeus zenkeri Harms and Uapaca guineensis Mull. Arg. They all three showed an aggregated structure, and that all scales of analysis. Observed aggregates have a radius of about 25 m distance. The analysis based on the diameter indicated an aggregated structure for smaller diameters and regular for larger and that aggregation decreases with diameter. The results also show that the observed spatial structures depend on the considered analysis of scale and the method used. The method of Clark & Evans is sensitive to the variation in the extent. In this regard, the random sampling of Hines & Hines appeared more suitable than that of Clark & Evans. Ripley's functions and derivatives are effective tools and provide more information. Analyses showed positive associations between G. dewevrei and S. zenkeri, and between G. dewevrei and U. guineensis. By against, independence was found between S. zenkeri and U. guineensis. It also appears that young people are positively associated with the supposed breeding adults and immatures are independent compared to adults. The low or limited seed dispersal near parent trees is the main endogenous factor responsible. This factor also explains the positive associations between youth and adults of the same species. The competition between individuals to space requirements, light or nutrients in the soil, explains the observed regular structure and the independence of immature towards adults. Limited dispersal, however, is not the only factor explaining the spatial aggregation trees, other factors such as environmental heterogeneity (soil, topography, ) or disturbance are probably also involved. Anthropogenic or natural disturbance is an environmentally friendly process that should have played a decisive role in the spatial organization of forest communities. Combined with masting phenomenon, the effects of Janzen-Connell and Ectomycorrhizae, it is very probably the basis of spatial structures and spatial relationships observed between species of the YFR.

Full textCurrent energy challenges are multidimentional in nature as they blend together the economic, social, and environmental fields. They are also global, interconnected and transversal. Energy challenges are apprehended globally by international law, despite some shortcomings. Those shortcomings stem from the strategic nature of energy challenges and their simultaneous dependance on sovereignty. They also come to light in the context of environmental risks and risks of harm to humans. Yet, those shortcomings do not deprive international law of its capacity to adapt to energy challenges. It shows adaptation by taking into account their transversal character and the correlated necessity for solidarity. The inclusive and new finality of pursuing universal access to sustainable energy and the efforts shown toward energy democracy yet reinforce this adaptability. Thus, international law exibits all the tools necessary to help, and also be an engine for the energy transition

Full textIIn central Tunisia, the agricultural intensification of irrigated agriculture generates local and regional environmental impacts, linked to an increased consumption of inputs and resources, including water and soil. In favor of a more sustainable agriculture and in order to inform public policies of agricultural development, it is necessary to assess the impacts of agricultural practices and water and soil conservation planning (WSCP), and this at the territory scale. The question is how to implement an environmental assessment approach in a context of 1) scarcity of reliable data including statistics, and complexity of farming practices, 2) prominence of socio-economic issues over environmental concerns 3) lack of knowledge of the perception of local actors on these issues and therefore of difficulty in identifying relevant indicators (scientific and of the stakeholders) and mobilizable. We propose an innovative approach to design and implement a participative approach involving different types of actors, to enable them to get more insights into each other's logic and perceptions of the impacts of agricultural practices and WSCP. This approach is designed to produce quality information by valuing local knowledge, share and take into account the perceptions of different stakeholders, and finally, build a consensus to contribute to the development of more effective WSCP policies. This approach has been structured in two main stages: the design of a community of practices articulated to a participatory systemic rapid diagnosis and the implementation of participatory workshops. The evaluation mobilized a dual mechanism including external observers and a satisfaction survey among participants. The survey is based on an evaluation grid of this approach, its outcomes and its short term induced effect. Sharing and taking into account the information and data collected, as well as the expertise and perceptions of the various stakeholders, has made possible to produce information deemed satisfactory or very satisfactory by all the participants. This nourished the knowledge of almost all the stakeholders and contributed to a constructive dynamic of collective learning. Our approach has contributed significantly to the evolution of perceptions and to a stronger mutual understanding between government officials and farmers. A dashboard grouping the indicators mobilized by each stakeholder was discussed and allowed to highlight convergences and differences in their analysis grids. The gradual and adaptive structuring of the approach, the choices of the stakeholders, the venues for the workshops and the use of a neutral facilitator were very important factors for the commitment and the mobilization of the stakeholders, in particular at the central scale, in this operational space for consultation on territorial issues, agricultural practices and WSCP. This work demonstrates the interest of integrating the engineering of consultation and environmental assessment within one approach and its feasibility in a difficult context for the ACES policies implementation

Full textThe thesis explores the socio-spatial meanings of several conflicting dynamics related to the environment, anddevelopment in a heavily industrialized territory. The analysis focuses on the reasons for and the genesis of mobilizations by inhabitants and actors at work since the 2000s around the Etang de Berre and the Fos gulf (Bouches-du-Rhône), a territory which has been partly annexed for a century to serve the development of the Autonomous Port of Marseille. The first part presents the main social sciences lessons which help to understand the conflict and offers a specific reading when the situation is tied to the existence of industrial risks. The second part is a photograph, enhanced by a historical approach, of the realities of the coexistence between cities and risky sites from the perspective of social representations of livedspace, environmental issues and industrial risk management policies. The third part seeks to restore and analyze several conflicts related to the implementation of an incinerator, port development, and the implementation of new regulations in matters of industrial, and urban risks. The thesis shows that the mobilizations are working on an update of the territory’s fractures and the environmental inequalities inherent to industrial territories. They are socio-political, environmental and democratic objects, and involve forms of territorial reappropriation and environmental justice. This research opens newperspectives in the study of the potential for the emergence of eco-citizenship and the social integration of environmental issues on territories which have a high ecological burden

Full textThe introduction of GMOs into agri-business has brought forth many public concems, such as the type of agriculture or the kind of foods we choose for our future, the safekeeping of our ecosystems and our cultural heritage, or matters of justice linked to ethics and equity. Our argumentation is that only a democratic process that offers to the citizens the possibility to express their views and concems on the development of GMOs will allow the authorities to make enlightened decisions on these matters. Moreover, many govemments have already shown interest in opening communication lines with the general public on the stakes created by these new technologies. This study analyzes different forms of public participation in the decision-making process conceming GMOs in three different countries, France, Switzerland and Canada. These models have been divided into three categories : the instruments of direct democracy, participation of different members of society in the evaluation processes, and public debates. We note that in spite of the efforts of the govemments to democratize decisionmaking in these matters, many factors such as technical reasoning into which decisions are inscribed as weIl as the inherent gaps of the representative model, prevent from taking the opinions of citizens into consideration. Therefore, we should ask ourselves about the relevance and the convenience of using the referendum to treat the concems associated with GMOs.
