Full textSince its creation in 1849, Libreville has experienced unplanned and uncoordinated urbanisation. Over the decades, this anarchic urbanisation has been accompanied by environmental imbalances and has subjected city dwellers to numerous ecosystem risks. This research focuses on anarchic urbanisation, its production universe and the resulting ecosystem risks. Questions that are not often addressed in Gabon are raised: how, by whom and why is anarchic urbanisation produced? What does this form of urban production reveal? To what extent does the production of anarchic urbanisation contribute to the increase in ecosystem risks? The answers are formulated along four lines. In the first axis, land use changes in the city were identified, characterised and analysed. Remote sensing and GIS tools were used to produce land use maps and risk maps. A second axis studies nature-society relations in Libreville, and highlights the perceptions of the city and nature, while identifying the benefits that the population derives from nature, and the ecosystemic risks to which the population is exposed. The urbanisation process underway in Libreville was characterised and analysed in a third axis. These last two axes are based on fieldwork using semi-directive interviews and life stories collected from local populations and actors. In the fourth section, a prospective view of Libreville was taken using land-use simulation maps. The results of this research show a rapid, significant and unstructured expansion of the urban area of Libreville and its surroundings, accompanied by significant deforestation of the region, mainly in the north. The dynamics observed in the city are the result of a vicious circle: anarchic land occupation, access to land by mutual agreement, land speculation, lack of land control by the state and laissez-faire, etc. These results show a widespread perception of nature degradation and conservation and protection practices by both city dwellers and decision-makers, a reduction in biodiversity and evidence of city-nature conflicts. The degradation and extensive deforestation of mangroves and the construction of houses are the main causes put forward by the respondents. Thus, changes in land use and impacts on nature lead to an increase in the ecosystem risks of flooding and coastal erosion, which are perceived differently according to age, location, professional status, etc. Continental erosion is very little perceived as a risk or a problem, despite mapping results showing exposed areas. As a co-production of local populations and actors, the various actors find an interest in uncontrolled urbanisation. Routines structure the co-production of space: precarious settlements, roads and tracks pave the way for urbanisation and deforestation, etc. A lack of synergy, conflicts of competence, insufficient decentralisation, financial mismanagement and excessive politics also mark this anarchic urbanisation. In a laissez-faire scenario, prospective land-use modelling shows a significant reduction in dense vegetation in protected areas. In a control scenario, on the other hand, it shows a conservation of almost all the protected areas. These situations, which provide information on the future of Libreville, raise questions about urban and environmental governance in Gabon. An attempt is therefore made to analyse the possibilities for change based on models of cities in Africa and the world, both on urban and environmental aspects

Full textThe 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

Full textThe most striking of these last forty years is the major transformation of Libreville, because of a very rapid urban growth. It is characterized by a high concentration of population and a dramatic expansion space mainly because to migratory movements. However, the constant arrival massive and uncontrolled populations in the city led to the proliferation of sub-integrated neighbourhoods, densely built and unhealthy. Indeed, when new immigrants arrive, their main concern is to find a roof. They have not at their disposal plots; colonize the empty spaces, inconstructibles, mostly beside the parent or the friend, first arrived in Libreville. This illegal occupation of spaces leads inevitably impact on the distribution plan landscape, and hence of urban development and especially the precarious land it caused. The public no longer able to offer land because of economic crisis, legitimate illegality by regulating land that originally were acquired unlawfully. Libreville has grown without any pattern of urban development. The existing land regulations do not guarantee access to the land for the greatest number. The procedures are lengthy and complex, which is likely to discourage those who want to venture. How to facilitate access to property to the greatest number, while respecting the harmonious development of the city? We have proposed revision procedures, adapting to the mores and customs of the people

Full textLibreville 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

Full textThis work proceeds of a report between the abstract districts and logics of actors of installation. By criticizing the town planning and installation imposed by the World Bank, the organizations of development as the French agency of development and the Canadian agency of international development, and on the local plan, the political actors (ministers, deputies, senators) true developers, we want to try out participative step who implies all the actors and takes account of the representations, the practices and the local habits. The conflicts of images which rise from these logics, lead to not-town planning. This is why the emergence of associations of district, the law on decentralization and of the actors such as the PAPSUT-PROTOTIPPEE, on the urban scene reveals the will to reduce these authoritative practices to the profit of a participative urban development

Full textPort Gentil is an industrial and harbour town relatively young. After having been the principal way of penetration of the interior of the country during the fifteenth century, Mandji remained a long time the stronghold of wood before becoming the economic capital of Gabon thanks to and especially oil which covers more 70% of the receipt of Gabon. This industrialization involved flows of populations to meet the industrial requirements in labour. Thus, Port-Gentil ast since the years 1950, the second most populated city country, in spire of the natural conditions unfavorable to the installation of the men. The city thus developed of its site initial towards the marshy west and whose altitude of the grounds is very in lower part of the sea level. Blow, the populations are victims of the floods. In addition, the installation of industries along bay of the Cape-Lopez and especially the infrastructures oil (pipelines and gas pipelines) became spaces at the risks. Because, the current urban development largely crossed these limits. Beyond the fact that Port-Gentil always does not receive on behalf of the State the rebate which it deserves, the city is today confronted with the problems of floods, anarchistic urbanization, an insufficiency maintenance of the network cleansing, of pollution industrial, and especially of a coastal erosion. All these risks are responsible for morphodynamic urban, harm pubic health and obstruct extension continues urban fabric. The stablishment of the men and the management of environment of Port-Gentil thus imply the control of these instabilities. That implies an application of the plan; installation and cleansing, the protection of the emissary of urban drainage and, the rigorous management of waste
