VITTURINI, ELIA. « The Gaboye of Somaliland : Legacies of Marginality, Trajectories of Emancipation ». Doctoral thesis, Università degli Studi di Milano-Bicocca, 2017. http://hdl.handle.net/10281/180856.
Texte intégralDrawing on fieldwork conducted in 2014 and 2015 in Hargeysa, the capital of the Republic of Somaliland (Somalia), the dissertation presents the historical and ethnographic reconstruction of the social position held by a cluster of minority groups. They have a much lower population than the other Somalilander genealogical groups and are instantly identified as being subject to certain forms of discrimination such as marriage segregation and being associated with occupational tasks despised by the rest of society. The most common denomination applied to them, across all Somali territories, is Gaboye. The main objectives of this research are to define the dynamic contours of this form of marginality and to reconstruct how it gradually lost the attributes of a social institution. Scholars and travellers of the colonial period defined this institution in terms of ‘caste’ because it implied the integration of ascribed status, notions of ritual impurity, occupational and marriage segregation. The analysis examines the trajectories of emancipation and the plastic ways of being at the ‘margins’ of political institutions and of economic networks that have affected the lives of the Gaboye from the colonial period until today. This historical and ethnographic investigation encompasses a range of aspects of the social, political and economic life of the people of the north-western Somali territories, the first of which is the urbanisation waves that started in the 1920s in the British Protectorate of Somaliland, and their implications for local populations. The subsequent ones are the transformations of ‘traditional’ institutions such as the co-contribution to blood compensation and the establishment of their genealogical group leadership, the different forms of inhabiting urban areas in the post-colonial and the post-civil war periods, the transformations of urban based businesses intended either as economic sectors or objects of social representations and finally the connections between contemporary forms of transnational migration and the reproduction of economic vulnerability.

Texte intégralLibreville the capital of Gabon makes face since the end of 1980s with important problems of insalubrity in touch with the solid waste. Developed geographical approach offers an analysis of correlations between the actors, their logic and means of action in an agglomeration marked by socio-space inequality to reveal the major dysfunctions which affect the quality of the urban service of the solid waste. The recent policies of decentralization and concession still do not contribute to resolve efficiently the problems of inequality of access to the local service of the solid waste because they are the object of institutional conflicts enters les for you and the State. The technical choices of elimination of garbage implemented by SOVOG, society private concessionary, do not take into account the diversity of the situations of development and equipment of the quarters of Libreville. That's why in the popular péricentraux and peripheral quarters, the populations which live in the enclosed shoals are excluded from the collecting of garbage. It is in this context that develop the informal practices of rejection of waste certain borrowed in the middle country. On the contrary in the rich quarters, the rates of collection are well brought up. The popular initiative which develops in quarters registers in a context of gouvernance and democratization still fragile and uncertain. Of this fact the public institutions remain the central actors of the management of waste

Texte intégralSolid wastes management has an impact on environment. It requires the awareness of the whole society, at every level. The insalubrity is an old phenomenon in Libreville, which leads to multiple mobilisations. It sets in motion all the social actors; so that is it deserve a study as a revelatory of social dynamics. The piling of waste damages the living conditions of the citizens. Public services, traditionally in charge of removing waste, are forced to reforms - delegation, decentralization. At the same lime, various individual and collective actors - environmentalist movements, citizens' organizations, and cottage industries- are trying to organize themselves. The inquiries on those processes have shown that the multiplicity of the actors and practices in the city, the territorialization of management strategies, and the deficit of regulation create disparities and tensions, revealing cleavages in Libreville's society. Votecatching, the solution chosen by authorities to contain social tensions, facilitates the inequalities in urban services by reducing the efficiency of the solutions imagined by inhabitants
Mouvagha-Sow, Myriam. « Processus matrimoniaux et procréation à Libreville (Gabon) ». Paris 10, 2002. http://www.theses.fr/2002PA100128.
Texte intégralGabon has a particular demographic context. Its fertility never reached very high levels because of a widespread pathological infertility, which appears to have decreased in a significant way these last years. According to the first Demographic and Health Survey (DHS), conducted in 2000, the country seems to have started its fertility transition, in spite of a pro-birth policy enforced until recently. Moreover, as in many African countries there is a marriage transition, marked by a significant delay of the marriage age and the development of informal unions. These evolutions -are caused by "modernisation" (increasing of educational levels, urbanisation, etc. ), but also by the economic crisis. In addition, changing fertility and marriage behaviours are tightly related to a redefinition of the relationships between men and women. The censuses and the DHS are not fully appropriate to the study of these transformations, because they give only a cross vision of them, whereas in Africa the constitution of the unions is a process which can be long and complex. Moreover, they do not take into account sexuality, visiting unions and male behaviours. Our research is thus based on interviews and a quantitative survey. The survey I conducted in Libreville in 1999, on a sample of 484 women and 424 men, deals with sexual, matrimonial and reproductive behaviours. It gives the detailed matrimonial history of the individuals, with the various stages of the marriage process, and their fertility biography. Thus, this thesis explores, partly with event history analysis, the matrimonial and fertility changes between different generations, the relationships between matrimonial life and fertility life and compares female and male life-cycles

Texte intégralThe study of the dynamics of the town of Lambarene made it possible to distinguish the various factors which contribute to the development of this city. On the geographical level, Lambarene occupies, a strategic position; it is the node of relation, the crossroads of communication networks road and river. Its central position and its economic assets explain the surge of the populations of various national and foreign origins. The multiplicity, the mixing and the diversity of those make of Lambarene a genuine melting-pot. With the economic plan and industrialist, whereas the small towns are in general mono-industrial, Lambarene is pluri-industrial. This character pluri-industrialist is due to a large number of foreign companies which strongly take part in the development of this urban area. The presence of these multinationals is revealing anchoring and opening of Lambarene to globalization. The interest of this study is articulated around the double demographic and economic dynamics which underlies the development of Lambarene and in fact an economic pole of importance in Gabon

Texte intégralSince a score of years, important upheavals characterize the sociolinguistic landscape of Libreville. These upheavals result in the fast increase of the local migrations, the integration of former rural zones in the urban perimeter, the schooling of the young people by the means of a language not of origin, but of great prestige, the reception of a great number of foreign populations having brought with them their languages. These phenomena of reorganization of space and contact of the languages and cultures became such extensive in the Gabonese capital in the period of colonial post modernity, that they gave the city the image of a strong, heterogeneous and multilingual company. The situations of contact of the languages and cultures are not without consequences. They imply changes relating to the linguistic behaviors of the groups and individuals. These changes are known and several researchers identified and studied them, in particular those concerning the dynamic socio-linguistic ones of the raised or undervalued languages. Main goal of this thesis consists in questioning on the uses of the local languages by young people of Libreville district (15-35 years). More specifically, it is a question of analyzing the impact of the social practices in use in the public places of sociability, through the word in order to highlight the extent of the practice of the local languages in the aforementioned districts. Generally, the results of the analyses are summarized as follows: - Firstly, three important languages are spoken in Libreville district among the linguistic exchanges. They are the fang, the punu and the nzebi. - Secondly, the declared knowledge of a language necessarily does not mean that its speakers include/understand it and/or speak it very well. - Thirdly, quarters of the east of Libreville are areas quality of life and linguistic territories favorable to the practice of the local languages of East Libreville, and the expression of the plurilingualism in local language

Texte intégralThe study of deposits of three lakes of Gabon revealed: At Kamalété two episodes were recovered: from 1410 to 520 BP, one observes the end of forest deterioration that central Africa knew between 2500-2000 BP. This episode is marked by a low lake level and a landscape slightly forester. Then, from 520 BP until today a wetter episode is characterized by a high lake level and a landscape increasingly forest. At Nguène, one notes three episodes. From 4110 to 2540 BP, a wet phase is characterized by a primary forest and a marshy environment receiving irregular fluxes from Abanga river. From 2540 to 1950 BP, forest deterioration is marked by an opening of the landscape and a marshy environment where sandy fluxes of Abanga river gradually disappeared. Lastly, from 1950 BP until today, one observes a new wet phase marked by a high lake level, a permanent communication between the lake and Abanga river and by a late forest renewal which took place only as from 990 BP. At Maridor, one notes three episodes. Former to 3795 BP, an immersion of the site would indicate a wet phase characterized by a marshy environment. During the second episode an emergence is due to a climate slightly wet around 3795 BP, it shows a podzolisation of the deposits. Lastly, the third episode of installation of the lake goes from ca. 3500 BP until today. It reveals three sub-episodes of which first going from 3500 to 2190 BP shows the forest deterioration that central Africa knew between 2500-2000 BP. This sub-episode is marked by a gradual opening of the landscape
Nan-Nguema, Sandrine. « Mémoires pétrolières au Gabon ». Paris 7, 2002. http://www.theses.fr/2002PA070076.
Texte intégralGabon's Petroleum memories began in the early 1900s. They are rooted in older memories from which they were fed. Territorial and genealogical knowledge of the nomad tribes represented the main aspect of collective memory during Gabon's pre-colonial period. Memory was transmitted through orality in a context of slavery. This context caused the appearance of a social hierarchy within tribes and among those established along the river Ogooué. Slavery was the first economic cycle to bind Europe to future Gabon. With the colonisation new memory contents based upon specialised economic cycles reshaped Gabonese societies. These cycles were mainly concentrated on small land extensions, in a little country counting few people. The exploiting of the Okoumé was the last of these cycles ; it started at the beginning of the 19th century thirty years before the petroleum conquest would follow the colonial and precolonial cycles inheriting and remoulding their own memories. The first Oil discovery in Gabon on the Mandji Island in 1956 occurred few years before the independence, in 1960. Once again, all the human energies of the country were focused on this cycle, which "petrolized" and urbanized the coast. This cycle reinforced the social hierarchies that pre-existed while adding new ones : national professional categories separated "Expatriates" from "Africans", and "Managers" from "Non Managers". An oil ideology was emerging. Written, it served both the Gabonese state and the oil company. Meanwhile, an orality of an injured memory was spoken among the lower classes of society. These memories were mixing, getting richer with the impact of politics and religion through collective or individual strategies of identity defence

Texte intégralThis academic dissertation is a reflection on the mode of management of infertile couples in Gabon. It gives a peculiar eyesight on the introduction and reception of medically assisted procreation ((MAP) in the Gabonese collective imagination. This research analyses in-depth, behavior, beliefs as to domestic infertility and the new reproductive techniques. Besides, this study reports changes/evolutions of family solidarity towards infertile couples. Many field data give rise to the opinion that medically assisted procreation would be the ultimate mean for fighting infertility regardless of its pretended witchcraft origins. Infertile couples hence find in such method the opportunity to take the spell off themselves, and also to free themselves from the "children threatening ogre" label. Individualization of Gabonese society implies that fostering is less approved: couples hence seek through medically assisted procreation a biological child rather than social

That implies firstly the revision of the alliens rights and secondly, benefits by giving them an approach more favorable for their legal status, and thirdly permits to thinking of some points conflicts of laws, mobile or interpersonal conflicts.

Texte intégralStomoxyine flies are hematophagous and represent, for man and his domestic animals, a plague by their direct harmful effect (harassing and blood predation), and they can be at the same time potential vectors of pathogenic agents. Those of the afrotropical region remain still badly known. The study of populations trapped in eight localities from Gabon made possible to identify seven species: Stomoxys calcitrans, S. N. Niger, S. N bilineatus, S. Omega, S. Inornatus, S. Transvittatus, and S. Xanthomelas. Population survey was carried out for 13 months in Makokou, along a transect crossing three environments: primary forest, secondary forest and a strongly anthropized area (a village). Results showed the major influence of each type of environment on the abundance of flies. The abundance was low in primary forest and very high in secondary forest and anthropized medium The S. Xanthomelas species is characteristic of the forest area while the S. N bilineatus species is strongly localised in the savannah zones. Except S. Omega, which is a crepuscular species, other species have a diurnal activity. The daily activity of the various species varies according to the environment. In primary forest they present a unimodal activity while in the two other media they have a bimodal activity. The stomoxyine flies take their bloodmeals on various vertebrate hosts of wild or domestic fauna, and sometimes on the man. The S. Transvittatus species is ubiquist, and mainly takes his bloodmeals on duikers (Cephalophus spp) while S. Xanthomelas prefers monkeys (Cercopithecus spp. )

Texte intégralThe site of Libreville is characterized by a hilly landscape, makes of hills, but especially boxed small valleys and wide swampy valleys: the slums. At first, the city evolved on hills and zones exshowers, avoiding systematically the stiff slopes, the boxed small valleys and the swampy zones. With the increase in population of the 1970s and in the absence of any planning, the urbanization continued in the slums creating sub-integrated districts where concentrate the main urban troubles. In the physical depressions thus settled down the social depressions, making of Libreville a city mined by the urban problems of any orders. The floods, the landslides and the collapses coexist with the insalubrity and the problems of health, the poverty and the precarious living conditions. The slums, still called matitis or mapanes, represent more than 80 % of the built surface today and are the expression of a not mastered urban growth. For a long time indicated as spaces of socio-spatial segregation, matitis is henceforth places of social coeducation where meet themselves populations of various social classes. To envisage the development of the Gabonese capital supposes the drastic arrangement and the viabilisation of mapanes. It also supposes that the local authorities take in hand and supervise the urban growth. For that purpose, the application of the principles of good governance turns out authoritarian in a city which lived at the rate of the more or less scandalous diversions of the public deniers. The eradication of matitis is a challenge for authorities and a chance for thousands of populations which live there

Texte intégralThis thesis is a reflection on the cohabitations outside marriage in Gabnon. It analyzes the changes in the process of marital union, in sexuality, in the family solidarity necessary to the constitution of the dowry or marital deal of a close relative who wishes to get married, in family roles with regard to sex and generations. Our conclusions show that marriage no longer constitutes the family basis and unions outside marriage also known as cohabitation have become the first stage leading to the union. With regard to the new forms of conjugality and to the aspiration of the couples, we notice that rules and forms of "traditional" matrimoniality reconstitute with the current transformations. The current process of social individualization reflects a changing society whose mechanisms are fueled by "traditional" as well as "modern" considerations. The Gabonese modernity is based on various cultures stemming from ethnic mix and from social models coming from outside
Ehazouambela, Doris. « L’islam au Gabon : socio-anthropologie politique d’une minorité confessionnelle ». Paris, EHESS, 2015. http://www.theses.fr/2015EHES0675.
Texte intégralThis study deals with Islam in urban areas in Gabon and aims at showing that Islam, as a primarily urban phenomenon, is now an integral part of the social, religious, economic and political environment of Gabon. Islam is considered a minority religion on a social level, and is practiced by a population consisting primarily of immigrants. However, due to conversions Islam currently occupies the second place among the religions of the Book in Gabon. The unique dynamics of islam in Gabon allow us to understand Gabonese social reality not only through the study of models and patterns, which preside over it in part, but also through the lens of religious practices, which demonstrate that that society is constantly in the process of renewing itself. In this way, we can examine how Islam structures historical situations and social organizations, as well as the existing gaps between "official" aspects of society and its social practices. Islam in Gabon is a minority religion that accomplished its social development and constructed its uniqueness on the local level, assisted by members of "political society" themselves converted to the faith of Mohammed, the Mamadous. These individuals consider Islam as one of their managing domains capable of reinforcing the power of the hegemonic block. In this way, the conversion to islam of President El Hadj Omar Bongo Ondimba and his entourage, combined with his political longevity, has established an imaginary in the Gabonese society, that is to say, a place for the construction of its social, economic and political history, both before and after the independence of the country. Thus, for the "political society", Islam in Gabon is one of the central elements of political and economic power, and it is constitutive of the dialectic of accumulation of "powers" of the reign of President Omar Bongo Ondimba. By bringing Gabonese population into new contingencies – notably religious - African modernity has tended to substitute lineages : that of the clan by that of the national community, that of the Church by that of the Mosque. This is "deparentelisation" which means an emphasis on social and political relations. Thus, through the conversion of deparentelized persons, the Mamadou and the Makaya, islam reconfigures and reconstructs the positions of the social and political relations in Gabonese society. Therefore, Islam in Gabon is part of the power structure called "phantom power" that operates on the basis of both visibility and invisibility
Nkoma, Ackye Gisele. « Les familles recomposées au Gabon : réalité, enjeux et discours dans l’exercice de la fonction parentale ». Paris, EHESS, 2012. http://www.theses.fr/2012EHES0548.
Texte intégralIn Gabonese society, blended families were traditionally due to fostering, levirate and sororate marriages, widow(er) hood, and polygamy which presented the advantage of allowing the family to function as an institution. Yet today, divorces, separations, remarriages and cohabitation have given way to new forms of blended families where the parental link is increasingly based on selection, which creates competition between blood relations and voluntary relations. These changes, which touch the social redefinition of relations within blended families, have been made possible with the adoption of a civil code since Gabonese families have gone from genealogical relations to biological relations. These relations celebrate the triumph of the conjugal family. In addition, the arrangements of the civil code have disqualified the statuses and cultural mechanisms that had previously permitted parents to raise children that were not theirs. From that point, the question of social redefinition of family relations was at the heart of the debate. In this context where endogenous and exogenous cultural logics confront each other, the joint exercise of the parental function within blended families is either legitimized or damaged. When it is legitimized, the real status of the spouse is hidden and the spouse assumes the role of social father or mother of a child. When it is legitimized, the real status of the spouse is unveiled and their position as the social parent by marriage is denied, they become a simple foster father or stepmother

Texte intégralWith the notice that, today, Gabonese ethnic languages are less spoken by the young, parents become more concern with the necessity to pass on their language to their children. The approach adopted here is based on the analysis of endogroup and exogroup phenomena. We examine, on the one hand the interaction process among members of a linguistic group, and on the other hand the relationships that speakers of different ethnic languages may have one another. Our study is backed upon declared usages stemming from a survey carried out in two Gabonese cities (Libreville and Lambaréné), chosen because of their multiethnic feature. It comes out from this survey that the family still stands as a trustworthy element for the transmission of ethnic languages in Gabon. However, conscious of the fact that the only domestic unit seems not sufficient enough for the maintaining of ethnic languages, we must consider their introduction in the curriculum. But with regard the failure of the various attempts to introduce ethnic languages in the education system, we start wondering about the range of the linguistic policies implemented on the national level. The review of these policies allows us to conclude that the learning of Gabonese ethnic languages needs first a language planning. Their statute is still precarious before the imperialism of the colonial language, French

Texte intégralThe rise of Asian interests has been one of the most significant developments faced by the logging industry in Gabon over the past two decades. Perceived as participating in China's strategy for access to natural resources in Africa, their presence raises concerns that highlight different webs of interests, both complementary and antagonistic, between a so called weak state and supposedly aggressive investments. This thesis aims to better understand these complex dynamics. The approach is interdisciplinary and examines society-environment relations through the lens of logging in Gabon. Based primarily on the socio-political and economic components of this industry, the analysis highlights the opportunistic character of the strategies employed by logging companies, by the State and by state officials. The shift to sustainable management fosters a hybrid form of forest governance, which favors the most adaptable economic strategies – notably those of Asian operators

La rampe paléogène comprend les trois éventails turbiditiques majeurs alimentés par de grands canyons, par contre, le système deltaïque montre des petits éventails à des vallées incisées et à des distributaires deltaïques. Douze lithofaciès fondamentaux correspondant à cinq environnements de dépôt ont été caractérisés sur carottes. Les debris flows et les faciès sableux de chenaux sont dominants dans les canyons miocènes, au droit du paléo-Ogooué. Le remplissage de ces canyons présente des séquences de groupement de chenaux d'origine allocyclique, en relation avec la structuration de la marge. Par contre, les séquences de remplissage des chenaux seraient liés à des processus d'avulsion. Leur superposition détermine une architecture générale rétrogressive, en relation avec une remontée du niveau marin relatif ; les chenaux deviennent corrélativement plus méandriformes. Les canyons éloignés du dépôt-centre présentent un remplissage contouritique dominant. Ce travail souligne la prédominance du forçage tectonique dans la construction du prisme de l'Ogooué

Texte intégralThe advent of specialization in Gabon due to the internationalization of the capital remains - far beyond the vicissitudes of history - the foundation of the sociological upheavals registered in this field. Nevertheless, the effects are so far slow to arouse the national integration, key-factor for the social progress for the emancipation of the national population. In fact, as a positively demographical phenomena, but a fundamentally sociological nature, the urban growth of Libreville remains at the same time the condensed and localized expression of the national development. Compendium of the fringes of society, the crises of decentralization and town and country planning that the urban growth socially but indirectly displays - considered from the point of view of the dynamic of specialization by the international division of work - are so many patents traces of these fringes. The only suitable therapy consists in the institution of a rational planification. However, the preliminary and compulsory condition is the advent of a really independent state, which is the judicial and thus legitimate emanation of the civil society

Texte intégralAs we know, the colonial period has produced a complex linguistic situation which also caused heavy social cultural implications in French speaking countries in black Africa, especially in Gabon. Overall, we observe a surperimposition phenomenon of languages on the hand French set as the language of power and prestige at the disposal of elites and civil servants, on the other African languages often reduced to a less laudatory status, as indigenous dialects not proper to teaching and acquiring scientific acquaintances. The purpose of this work is to help us understand and know, the speaking and promotion of French around the world as a cultural force and a kinetic energy in the building up of a Gabonese nation that is in motion since its independence in 1960. Our main purpose isn’t to justify the speaking and promotion of French around the world but to show the contribution it has brought to the building up of a friendly and prosper Gabon ever since the French language arrived on the Gabonese soil

Texte intégralThe study of gabonese broadcasting, television and press accentuates the close links between media and politics. Though, for a long time, radio and television were considered by the leaders as instruments of power, justifying the existence of state monopoly. This one was maintened until the end of eighties by law nʿ 4/89 of july, 6th 1989, determining the legal system of broadcasting and television in Gabon. The democratic wave that spread over French Africa in the early nineties didn't spare Gabon. Indeed, the political evolution towards multipartism thanks to the National Conference (Libreville, march 27th - april 21st 1990) was accompanied by an undeniable media pluralism. Beside the traditional public sector, a private one grew. Press, governed in the past by law nʿ 84/59 of January, 5th 1960, about freedom of the press ant thought was even touched by those changes. For the moment, many papers - thirty or so - were created. This quest for freedom was especially translated into will of redefine the communication laws. Therefore, the edict nʿ 7/93 of October, 1st 1993 about audiovisual, press and film communication was adopted. In the same way, the Constitution of march 26th, 1991 modified assert once again and establish the fundamentals principles of freedom of thought, expression and communication. It also establishes a regulatory authority of media (the National Council of Communication) and a constitutional Court, both in charge of assuring and looking after pluralism in press and audiovisual communication, which pluralism has a constitutional value

Texte intégralThe 2007-2008 world food crisis, once again, has somewhat laid emphasis on the serious handicap of the Gabonese agricultural sector, though seen as the top priority of the economy. Gabon is undoubtedly one of the rare Sub-Saharan countries where agriculture, cattle breeding and fishing combined are less than 6% of the GDP. The dominating feature of oil, mining activities and the inadequate agricultural policy of the authorities (with a clear agricultural option) have ended up creating not only a deep gap between the various branches of the economy, but also resulted in a tremendous urban growth. Those changes have occurred to the detriment of the Gabonese rural area, emptied of its most valid forces. In the food-producing sector, the agricultural methods have remained unchanged, rudimentary and hardly productive. Despite their recent setting up of a market gardening belt around the main towns (especially Libreville), Gabonese peasants still lack dynamism and competitiveness. Their incapacity to draw substantial revenues from their activities and save money cripples their effort to contribute to the economic growth of the country. All the agricultural parameters are on the wane and keep the national output below the food needs of the populations, which makes Gabon depend on foreign foodstuffs heavily

Texte intégralIn 1993, the census estimated the number of unemployement people at 67,000 in a labour force of about 470,000. The official unemployement refers to the statistics numbers developed by the employment national office (eno) in accordance with the standards of the international labour office (ilo). The unemployment represents all those who - at any time- enterred the labour market and then left it or been laid off for various reasons. So, is it appropriate to talk about unemployment in a society in which labour relations are not very developed, both because of the lack of the state policies and the consequent size of an informal economic sector? while referring the study of unemployment to libreville, the author reveals that every unemployed workers are not necessarly devoid of profitable activities. The jobless activities fit into the odd jobs framework. These activities which are the competence of the informal labour in urban area represent odd jods such as pieceworking, fritters sale, door to-door selling, photographs and so on. The odd jobs, according to wages it procures avoid the libreville inhabitants to suffer from the fringe in an area in which the social element remains the monetary income

Texte intégralThe Gabon of todays is caught between two different worlds with strongly antagonist values : the sacred traditional society versus the modern and materialistic world. That duality naturally applies as for as justice is concerned. The western type for justice and the informal type coexist in opposition and reflect the daily experiences of the Gabonese people. For that reason, the situation of the judge is indeed very uncomfortable, his dilemma is in deciding whether to render justice that is rooted in the law or one that is reflection of Gabonese society. At a time when there is a lot of talk about acculturation, underdevelopment, crisis of the judiciary system and when by the same token we are also witnessing the clamoring for a state of law in Gabon, the recognition of customary law does not derive from any dream or love of past. On the contrary, taking into consideration its general principles can lead to the construction of a modern system of law, truly rooted in Gabonese culture with the advantage of being understood, recognized and respected. This unique and original system of law which embraces the cultural values and is able to transcend and is also capable of evolving by integrating modern values. Judges could become tomorrow's masters. It is up to them to follow the wisdom of their ancestors in order not to become despots. The sources for the elaboration of a new law could also be obtained from experience in the African countries i. E. Beyond the frontiers of Gabon. Beyond the concepts and technique the system of law is also a certain way of looking at the world, the social interactions and justice

Texte intégralAs an exporting country of raw material among which petroleum wood manganese and uranium ), gabon has nothing but the sea way to sell outside its outputs having efficient port facilities at one's disposal is there fore something essential. That is why the gabonese state has undertacken a number of projects in order to make the equipements of its major maritime outlets - which are libreville and port-gentil - meet its commercial needs. Throughout those port equipements, the state has intended to carry out a real economic development policy in the country following this triple objective: opening the country to the outside word, promoting its industrial progress, and contributing to town and country planning. After a working which has been lasting for more than twenty years one can wonder whether the different facilities in the harbours of libreville and port-gentil are sufficient to endow the country with an excellent maritime service or other plannings should be conceived for a balanced development. Do the existing infrastructures meet the maritime wants of the country? as owing to data concerning the gabones coast as well as those related to nature, people and all endeavours in favour of a national intergration, what could be the future of gabonese ports? those are some of the questions to which our survey tries to give answers

Texte intégralGenerally speaking, the purpose of this project is to clarify the notions of risk and trust, particularly with regards to banking, insofar as questions relating to bank financing for SMEs in Gabon, as in the majority of African society, are often clouded by an understandably excusable inclination to write off the enterprises' difficulties as a simple result of financial difficulties. Pitting such an analysis against the basic realities of underdeveloped economies demonstrates the variety of constraints that the overall environment exerts on banks and the entirety of economic operators. The limitations related to the irreducible particularities of the businesses must be taken into consideration. Where risk is concerned, the cumulative constraints engender exceptional risks, explaining not only the epiphenomenal nature of the financial constraint, but also an accrued difficulty of credit risk evaluation. An ensuing credit rationing phenomenon becomes more an imperfect means of limiting bank risk rather than an efficient selection mechanism. Further, without pretending to provide blanket solutions for formidably complex problems, we were able — for the benefit of the country's fledgling economic law — to glean a few implications relative to policies that would diminish the risk aversion of certain economic operators and thus make the pertinent decisions. Restoring the trust that is the cornerstone of both credit and business in general is an integral part of such orthopraxy. For neither law nor economics can attain their goals without trust

Texte intégralIn the 1990’s, Gabon started the army’s professionalization. It was the continuation of theinstitutional reforms that came from the society democratization and the reform of the State.Indeed, after the frustration crisis and the 1964’s putsch which ensues from it, the single-partysystem introduced nepotism at all levels of the gabonese army. This army was since, and until1999, in the classic pattern of the « huge bureaucracy in charge of spying and crackingdown » like many black african armies. Turned into a pretorian army, the gabonese army wasseparated from the State, its former employer. Subject to the profesionalization, the gabonesearmy is now reorganizing, restructuring and rationalizing itself. So adopting a new positionbesides the State, the gabonese army is progressively affirming itself as a sociopolitical actor.This research work relies on strategic documents, concrete facts and empirical data to analyzethe transformation (structural and organisational) of a state institution and of its new rolebesides State, Society and Nation

Texte intégralThis thesis has for objective to examine the mechanisms governing the corporatist dynamics and logics of action of the collective of teachers in Gabon. This reflection has been directed at the outset by two observations: the teacher collective action and statutory changes marking the evolution of this occupational group. The methodological approach relies on the contribution of several disciplines of social sciences and various theoretical approaches. The theoretical assumption rests on the idea of the creation of a corps of business. This thesis attempts to apprehend the profession of schoolmaster from a triptych linking three areas of analysis: social relations, organization and social context.The field survey conducted among different educational actors, mainly teachers, is centered on the life and work of these conditions. The analysis focuses both on the statutory aspects, relations between teachers and other actors of the educational action - mainly students, families, public authorities - and the daily practice of the class. It highlights, the plurality of professional identities and professional practice variability following relational configurations, organizational rules, and, the social and cultural context of work. For example, the significant teacher in a village becomes an employee being poorly paid in the city. Similarly, when the management of discipline in the classroom, the multiplicity of varied activities, looking for teaching tools, maintenance of the class, punctuate a morning's work of public school teacher and of his students, the maximum exploitation of the many educational resources available characterized a morning's work of the partner school teacher.The analysis can also identify the mechanisms underlying the agreements and disagreements within the school system in its entirety. Training devices not adapted to the actual conditions of work, the marginalization of the teacher in the province, the expectations of the families against the teacher in his home village, leakage of exam classes or oversized classes by some teachers, the constitution and the management of budgets in institutions, radicalization or non of Union action... are all factors sources of opposition characterizing the relationships of teachers between them teachers with parents of students or the public authorities

The following stage deals with handling and consumption by different households. However handling of halieutic products encounters many problems : - shortage and bad quality of fish retailers' equipment - insufficiency and bad quality of roads - maladjusted or non-existent of landing and conditioning infrastructures. In such conditions, one should fear the non realization of fish-markets development projects

Texte intégralThe purpose of this study is to develop a business framework for enterprise development and venture creation in Libreville, Gabon. The question that guides this research is: How are hotels and restaurants created and developed in Libreville, Gabon? The level of poverty and the unemployment rate have pushed many people to become creative in finding a way to generate income. The resultant entrepreneurial activity is a key element in the potential economic growth of the country. The Gabonese Government took the initiative to promote SMEs by providing the necessary economic environment. However, from a financial perspective it appears that the majority of entrepreneurs are using their own capital to finance their business during the start-up and developing phases. The limited access to finance remains a major issue for entrepreneurs in both developed and developing countries. It is an ongoing challenge for them to acquire financial support from the available financial institutions. In order to make this study effective, a quantitative approach was followed. A selfadministered survey questionnaire was distributed to seventy owners and managers of hotels and restaurants. The findings show that the key elements which lead to the failure of SMMEs are; the limited access to finance to start up a new business, the lack of funds to maintain operating expenses during the start-up stage, the low return on investment and the mismanagement and poor understanding of the financial cycle of a start-up. Therefore this study proposes a business framework for venture creation and development so that entrepreneurs in Libreville will become educated in the correct procedures to successfully manage and grow their businesses, which will have a positive effect on the economy as more businesses become self-sustainable. SMMEs are regarded as an important means of addressing unemployment and poverty and boosting the economy of the country.

Texte intégralThanks to its abundant natural resources and its relatively high standard of living, gabon has experienced considerable migratory flows from ather african countries. These have mainly concentrated in the urban centers, and more particularly in libreville, the state's capital city. To this oil-boom-encouraged wave of immigration, it has to be added a phenomenon of rural depopulation that is not without urbanization consequences. The resulting situation involves some alterations in the city structure and the population's way of life along with the creation of new (informal) activities in order for this latter to adjust the urban environment. Obviously, the population explosion originating from that townsmen grouping, in the one hand, poses health, transport and accomodation problems with corollary is the manifest expansion of underintegrated areas (and districts) as well as environmental damages, and, in the other hand, it increases the country's employment difficulties as the very time when this latter undergoes structural adjustment measures limiting the state's capability of resorbing unemployment
