Alors qu'un peu plus de la moitié de la population mondiale vit en ville depuis 2007, les espaces urbains semblent être devenus les lieux de cristallisation des enjeux du XXIème siècle, du réchauffement climatique et de ses conséquences aux inégalités sociales et territoriales qui se creusent chaque jour davantage. L'explosion démographique de plus en plus galopante que connaît l'Afrique subsaharienne et son lot de difficultés accentue les inégalités. La population africaine double en effet tous les vingt-cinq ans. Cette situation pose le problème crucial de la prise en charge des besoins des citadins en matière d'équipement, de réseau et de planification, de construction durable, d'urbanisme, de la gestion du foncier, d'assainissement, de l'économie circulaire, de mobilité, du transport, de l'accès à l'eau, etc. C'est dans ce sens que s'inscrivent les Agendas 21 locaux qui est la déclinaison au niveau local des conclusions de la Conférence de Rio (1992). Depuis, des initiatives nouvelles pour une ville durable sont mises en évidence partout dans le monde ou sont en phase d'expérimentation dans les projets d'aménagements urbains. La ville est ainsi peu à peu identifiée comme un lieu de développement et d'expérimentation de « bonnes pratiques » du développement durable. L'objectif de cette thèse est de contribuer significativement à une base de réflexion synthétique pour l'aide à la décision et la programmation des projets et programmes d'aménagement en Guinée-Bissau et au Sénégal. Deux types de méthodes différentes mais complémentaires ont été combinées. Il s'agit de consulter les documents d'archives et mener des enquêtes sur le terrain auprès de personnes ressources pour compléter mon travail de terrain. L'approche s'est appuyée sur un regard transversal et croisé des thématiques interdisciplinaires du développement durable en insérant les questionnements propres à la conduite des projets et programmes d'aménagement urbain.

ISBN: 3030376354

This book brings together the papers presented at the Smart and Sustainable Built Environments Conference, 2018 (SASBE).This latest research falls into two tracks: smart and sustainable design and planning cities; and the technicalities of smart and sustainable buildings. The growth of smart cities is evident, but not always linked to sustainability. This book gives an overview of the latest academic developments in increasing the smartness and sustainability of our cities and buildings. Aspects such as inclusivity, smart cities, place and space, the resilient city, urbanity and urban ecology are prominently featured in the design and planning part of the book; while energy, educational buildings, comfort, building design, construction and performance form the sub-themes of the technical part of the book. This book will appeal to urban designers, architects, urban planners, smart city designers and sustainable building experts.

Human activities are significantly modifying the natural global carbon (C) cycles, and concomitantly influence climate, ecosystems, and state and function of the Earth system. Ever increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands. However, land-based sinks require long-term management and a protection strategy because C stocks grow with a progressive improvement in ecosystem health.

Multi-party Elections in Africa

Genre: Literary Collections
ISBN:

This volume contains electoral studies of multiparty politics in 14 African countries during the 1990s. Most are about national elections in Anglophone Africa. There are also less well-known examples from Sudan, Ethiopia and Guinea Bissau. The collection also features studies of the local elections in Namibia and of a significant by-election in Malawi. The multiparty period had been put, wherever possible, within the historical context of earlier elections in Africa. Questions addressed include: how did incumbent governing regimes learn to live with multiparty politics? Why have some elections been so closely fought and others have suffered from apathy? Why has there been relatively open political expression and activity when the elections have increased the political and economic manipulation by incumbent governments? Why have the elections of the 1990s been so marked by local and ethnic variations? To what extent did this wave of democracy result from pressure from donor countries?
