Mots clés : Groupe à Haut risque - Typologie - TS - HSH –VIH -IST- Afrique CentraleProblématique : Les femmes travailleuses du sexe (TS) et les hommes qui ont des rapports sexuels avec des hommes (HSH) constituent les populations les plus à risque d’infection au VIH dans différents pays d’Afrique subsaharienne. A ce jour, très peu d’interventions sont menées pour réduire le risque d’infection en influant sur les facteurs de risque dans ces deux populations en Afrique Centrale et particulièrement en République Centrafricaine. Les objectifs de cette thèse étaient d’établir une typologie documentée des transactions sexuelles féminines à Bangui et de mesurer la prévalence du VIH et des comorbidités associées dans ces deux populations.Méthodologie : D’abord de 1384 femmes volontaires sensibilisées ont été recrutées sur les lieux de leurs activités et orientées au niveau du site de l’enquête. Parmi lesquelles 345 ont été identifiées comme travailleuses du sexe. Et, par effet « boule de neige », 131 Hommes ayant des rapports sexuels avec des Hommes (HSH) ont été recrutés pour constitués la deuxième population de l’étude. Des analyses biologiques ont été effectuées. Un volet d’entretien est réalisé auprès de 20 TS.Résultats : Les résultats en ce qui concerne les TS montrent que cette pratique est très hétérogène et que la prévalence du VIH varie selon les catégories. Ainsi, la prévalence du VIH était de 6 fois plus élevé chez les "katas" que chez les "pupulenge" (39,1% contre 6,3%). Parmi les TS non professionnel, les «élèves/étudiants», «fonctionnaires ou salariées » et «femmes au foyer» étaient moins infectées par le VIH (6,1%, 9,8%, 13,0%, respectivement), tandis que les «vendeuses ambulantes», constituait la catégorie la plus touchées par le VIH (31,9%). Et, l'infection à VIH était fortement associée à la pratique du sexe anal avec les clients (OR ajusté, 4.3), à l'utilisation ou non du préservatif avec les clients (OR ajusté, 24.9), à la consommation d'alcool avant le travail du sexe (OR ajusté, 2.8) et à la notion d’antécédents d'IST (OR ajusté, 4.2).La population de HSH à Bangui est identifiée pour la première fois comme un groupe à haut risque pour l’infection à VIH, étant 5 fois plus infectées par le VIH que la population générale d'adultes hétérosexuels. Parmi eux 20 % étaient infectés par le virus de l'hépatite B (VHB) (Ag HBs), dont 6 cas étaient co- infectés par le VIH et le VHB et dans 3,8 % cas la sérologie positive pour la syphilis. Les HSH à Bangui ont donc besoin d'interventions d'urgence spécifiques de prévention et de soins de santé.Conclusion : Les résultats de ce travail permis de mieux caractérisés et documentés les populations des femmes TS et les HSH à Bangui. Deux groupes de populations « originales » pour la République Centrafricaine, vulnérables et à haut risque d’infection à VIH. / Keywords : high risk group- typology - FSW - MSM –HIV -STD- Central AfricanBackground: The population of female sex workers (FSW) and the group of men who have sex with men (MSM) constitutes a priori an important core group of HIV transmission. In the context of the Central African Republic the situation of FSW and MSM is yet unknown. The objectives of this thesis were to establish a documented typology of female sexual transactions in Bangui and to measure the prevalence of HIV and associated comorbidities in these two populations.Materials and Methods: First 1384 sensitized female volunteers were recruited to the site of their activities and oriented at the survey site. Finally, 345 FSW questionnaires were selected for study analysis. MSM were recruited on a voluntary basis by the way of local network of nonprofit organizations working in the field of HIV infection. Included MSM were referred to the National STD center of Bangui for social, behavioral and medical evaluation. After collection of social and behavioral characteristics, each participant received a physical examination and a blood sample was taken for HIV and STD testing.Main results: Female prostitution in the CAR is remarkably heterogeneous. Risk-taking regarding HIV infection is very different between each category of female prostitution. HIV varied according to FSW categories, Thus, HIV prevalence was 6-fold higher among « kata » than « pupulenge » (39.1% versus 6.3%).Among non professionnal FSW, « students », « civil servants » and « housewifes » were the less infected (6.1%, 9.8%, 13.0%, respectively), whereas « sellers » constituted the category of highest HIV prevalence (31.9%).HIV infection in the whole study FSW population was strongly associated with anal sex practice with last clients (adjusted OR, 4.3), condom use in last 3 months (adjusted OR, 24.9), alcohol consumption before sex (adjusted OR, 2.8) and past history of STIs (adjusted OR, 4.2). The population of MSM in Bangui is identified for the first time as a yet unexpected high-risk group for HIV, being 5-fold higher HIV-infected than the general adult heterosexual population. The 131 (100%) MSM accepted blood sampling: 24 % were HIV-1-infected; 20% were infected by hepatitis B virus (HBV) (Ag HBs), including 6 cases of co-infection by HIV and HBV; 3,8 % showed positive syphilis serology. The MSM in Bangui, needing urgently specific interventions for prevention and heath care.Conclusion: The results of this work led to better characterized and documented populations of women and TS MSM in Bangui. Two groups population "original" for the Central African Republic, vulnerable and at high risk of HIV infection.

Depuis 1996, conflits armés, grand banditisme (coupeurs de route) et razzias ont forcé des centaines de milliers de Centrafricains à migrer, à l’intérieur de leur pays (déplacés internes) ou vers l'étranger proche (réfugiés au Cameroun et au Tchad). Au travers divers courants de la géographie (politique, du développement, des mobilités), ce travail montre que les migrations forcées se construisent au croisement entre les pratiques des migrants et les choix politiques des structures d'encadrement (États, groupes armés, organisations d'aide humanitaire). Il se fonde sur une approche transversale de la migration forcée (du lieu d'origine au retour éventuel) et sur des enquêtes de terrain multi-situées (Centrafrique, Cameroun, Tchad). Une première partie démontre que les violences ne sont pas causées par la faiblesse de l'État centrafricain, mais par les politiques de ses dirigeants. Les populations sont prises pour cible dans des conflits irréguliers pour contrôler l'appareil d'État et par des groupes armés qui pillent les ressources (bétail, récoltes, infrastructures publiques, diamants). Une seconde partie montre que si les insécurités jouent sur l'ampleur, la répartition spatiale et la durée des exils, les migrants orientent leurs cheminements selon leurs habitudes circulatoires. Ils empruntent divers champs de mobilités pour fuir les violences (mobilités agricoles et pastorales, relations villes-campagnes). Une troisième partie met en perspective le rôle de l'aide humanitaire et des politiques d'asile dans la production de l'espace migratoire, autour de deux formes d’accueil : les camps de réfugiés, la dispersion des migrants dans des villes et des villages. / Since 1996, armed conflicts, organized crime (road bandits) and raids have forced hundreds of thousands of Central African Republic people to migrate within their own country (IDPs) or to bordering countries (refugee in Cameroon and Chad). Through various geographical schools (political, development, mobility), this work demonstrate that forced migrations results from both the practices of migrants and the political choices or the supervisory organizations (states, armed groups, humanitarian organizations). It is based on a transversal approach of forced migration (ranging from the starting point of the migrant up to his possible return) and multi-located field surveys (CAR, Cameroon, Chad). The first part shows that violence is not caused by the weakness of the CAR state, but by the policies of its leaders. The populations are targeted in the course or irregular conflicts aimed at controlling the political machinery and by armed groups plundering ressources (livestock, crops, public infrastructure, diamonds). The second part shows that if insecurities influence the extent, the spatial distribution and the duration of exiles, migrants direct their paths according to their regular circulations. They use various fields of mobility to escape violence (agricultural and pastoral mobility, urban-rural relationship). A third part put sinto perspective the role of humanitarian aid and asylum policies in the production of the migratory space (refugee, camps, dispersion of migrants).

The internationalisation of conflicts has made the study of the effects of external support a prominent subfield within peace and conflict studies. How supporting states affect conflict strategies and changes the conflict dynamic has been the prime concern of this thesis. I have argued that when a government actor is supported by an external state with high soft power, in the form of political and economic capital, the government is less inclined to use one-sided violence as a conflict strategy. By using the principal- agent theory as a model to explain the relationship between the supporter and the supported state, I have found support for my argument. The government of the Central African Republic has conducted low levels of one-sided violence when supported by the soft power France. The government of South Sudan, on the other hand, has conducted high levels of one-sided violence when supported by the non-soft power Uganda. By coming to this conclusion, this paper has introduced soft power as an important concept in peace and conflict studies while also helping to elucidate the role of external supporters in conflict strategies. Future research should develop on the findings in this thesis by controlling for other possible explanations to why one-sided violence decreases depending on the characteristics of the support and include a greater number of cases.

Private Military Companies (PMCs) have increased significantly since the end of the Cold War, primarily hailing from the Western countries and South Africa, and notably employed in the War on Terror. In recent years, the Russian group generically known as ‘Wagner PMC’ has been deployed in Ukraine, the Middle East and Africa. While often referred to as Russian ‘proxies’, the Wagner group has not previously been analysed through the lens of proxy theory, and academics are divided on whether PMCs may be considered proxies at all.  Russia’s intervention in the Central African Republic through Wagner provides an important case to study this new development. Employing a theoretical framework combining elements from both proxy and PMC literature, this thesis contributes to both fields by suggesting key analytical elements through which a PMC may be considered a proxy and explains how this alters the dynamics between the intervener and its proxy. Moreover, this permits a novel analysis of Russian strategies to expand its influence in Africa, suggesting that intervention through Wagner may serve as a model for interventions in other weak countries requiring security support.

Bien que le Code de droit canonique prévoie au canon 281 la rémunération des clercs et leur assistance sociale en cas de maladie, d’invalidité ou de vieillesse, cette disposition est loin d’être appliquée convenablement aux prêtres séculiers de Centrafrique. En plus de la pauvreté structurelle, le pays est en proie à une guerre civile qui a détruit tout le tissu socio-économique. Mais la guerre ne justifie pas tout. Il y a un problème de gestion et d’administration des biens ecclésiastiques. La gestion rigoureuse et transparente des maigres ressources financières dont dispose l’Église reste un défi majeur. S’il est vrai que la subsistance du clergé est de la responsabilité de l’Église, les prêtres ont aussi une part importante à jouer. Notre thèse propose les mesures à prendre pour rendre possible l’auto-prise en charge des prêtres en Centrafrique. / Although the Code of Canon Law provides at canon 281 the remuneration of clerics and their social assistance in case of sickness, invalidity or old age, this provision is far from being properly applied to the secular priests of Central Africa. In addition to structural poverty, the country is in the throes of a civil war that has destroyed the entire socio-economic fabric. But war does not justify everything. There is a problem of management and administration of ecclesiastical goods. The rigorous and transparent management of the meager financial resources available to the Church remains a major challenge. While it is true that clergy subsistence is the responsibility of the Church, priests also have an important part to play. Our thesis proposes the steps to be taken to make possible the self-reliance of the priests in the Central African Republic.

Cette thèse propose une description ethnographique et une analyse sociologique de l’arrivée des traitements antirétroviraux (ARV) à Bangui, c’est-à-dire de cette rencontre singulière entre un programme international à l’ampleur inédite et une société locale durement touchée par l’infection. S’appuyant sur trois années de terrain entre 2005 et 2011, la démarche qualitative vise à répondre à la question suivante : de quoi les antirétroviraux sont-ils vraiment l’incorporation ? Les programmes d’accès au traitement constituent un pouvoir thérapeutique qui se structure comme une « politique de la vie » mettant en lien ARV, ONG et une histoire postcoloniale. La distance entre les prétentions et les réalités du pouvoir thérapeutique explique les ambivalences ressenties lors de l’incorporation biologique et sociale des ARV. Le pouvoir thérapeutique dans le contexte social centrafricain se caractériserait alors moins par des formes exclusivement biomédicales de subjectivité, que par un processus d’individuation fragmenté, basé sur des pratiques biomédicales souples, démonstratives et oublieuses. Il apparaît alors clairement que les programmes internationaux de traitement de l’infection à VIH contribuent à produire de l’oubli ou plus précisément à écrire l’oubli à partir des « pratiques scriptuaires »: l’oubli des histoires individuelles enchâssées dans des inégalités sociales insurmontables, mais aussi l’oubli d’une Histoire plus longue qui montre que l’infection à VIH est l’incorporation d’un passé colonial. Prendre un temps pour reconnaître ces temporalités du traitement paraît alors de plus en plus nécessaire pour construire un présent qui émancipe, plutôt qu’il ne répète. / This thesis proposes an ethnographic description and a sociological analysis of the arrival of antiretroviral (ARV) in Bangui. It highlights the encounter between an international program with an unprecedented scale and a local society hardly hit by the HIV infection. The qualitative approach, based on three years of fieldwork from 2005 to 2011, aims at answering the following question: what are ARVs really the incorporation of? Treatment programs represent a therapeutic power that is structured as a « politics of life » linking medicines, NGOs and postcolonial history. The distance between the claims and the realities of therapeutic power explains the ambivalence felt in the biological and social inclusion though ARVs. Eventually, we observe that the therapeutic power in the Central African social context is less characterized by exclusive biomedical forms of subjectivity than by a fragmented process of individuation based on flexible, demonstrative and forgetful biomedical practices It appears then increasingly clear that international programs for the treatment of HIV infection contribute to produce oblivion or more precisely write oblivion with "scriptural practices", which is to say the oblivion of individual stories embedded in insurmountable social inequality, but also the omission of a longer history which shows that HIV infection is the incorporation of a colonial past. Taking time to recognize these temporalities of treatment then appears increasingly necessary to build a present that empowers, rather than repeats. / Réalisé en co-tutelle avec le laboratoire Santé-Individu-Société, Ecole doctorale Interdisciplinaire Sciences et Santé, Université de Lyon, avec l'obtention du grade de docteur en sociologie.

The Örebro Mission was founded by John Ongman in 1891. Missionary work in Central Africa began through Ongman’s local church in 1914, at first within other mission societies, but was later continued by the Örebro Mission. From 1921 the Örebro Mission developed its own work in Middle Congo and Oubangui-Chari within French Equatorial Africa. The aim of this thesis is to study how the process of change took place, starting with pioneering work undertaken by Swedish missionaries and resulting in the founding of independent Baptist churches. The analysis is based on the classic three-self policy, aiming at self-governing, self-supporting and self-extending indigenous churches. Using the principal-agent perspective in history writing, the role and significance of a number of key persons are focused. The interaction between the internal process and the cultural, political and ecumenical contexts is taken into consideration. The thesis shows that the three-self formula was used from the beginning as a theoretical goal, but also that its realization was seen in a very long time perspective. Several steps were gradually taken in that direction, but the study shows that contextual factors became as important incitements for the change as the missionaries’ own theologically based motives. It rather took “a second conversion” from a colonial mental framework to speed up the process in its final phase towards the creation of African denominations and the integration into them in 1962 of the Swedish mission structure and work.
