Download or read book La question nerg tique au Sahel written by Jean-Paul Minvielle and published by KARTHALA Editions. This book was released on 2000-01-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: La totalité de la consommation d'énergie des 8 pays sahéliens continentaux membres du CILSS ne représente que 1 % de celle de la seule agglomération new-yorkaise ! Et pourtant, malgré cette faiblesse, la seule consommation domestique d'énergie suffit à détruire progressivement un environnement forestier fragile. Les faibles niveaux de développement atteints, caractérisés par l'écrasante prédominance des usages thermiques domestiques sur les usages mécaniques productifs de l'énergie, combinés à une croissance démographique toujours forte, dessinent un avenir préoccupant. Si les tendances actuelles ne sont pas renversées, il n'est pas exagéré de penser que la communauté internationale sera rapidement confrontée à la nécessité de fournir au Sahel une aide énergétique, de la même manière qu'elle a été amenée, depuis le début des années 70, à assurer à cette région une aide alimentaire permanente.

Available in PDF, EPUB and Kindle. Book excerpt: Au Sahel, le bois-énergie, sous une forme brute ou sous forme de charbon, est la première source énergétique des populations rurales et urbaines. La demande croissante des grandes villes fait peser sur les ressources forestières avoisinantes une pression de plus en plus forte, pouvant remettre en cause leur durabilité. Dans ce contexte, la question de l'organisation spatiale des bassins d'approvisionnement des villes sahéliennes, est un enjeu majeur pour la définition de politiques de gestion à long terme des ressources ligneuses. La modélisation spatiale de l'aire d'approvisionnement de Bamako (Mali), utilisée comme un processus heuristique, permet de mettre en évidence les déterminants de la localisation et de l'intensité des prélèvements. Il apparaît que le facteur principal d'explication des flux de bois réside dans l'organisation des ventes de bois en milieu rural. La présence d'une foire hebdomadaire ou d'un marché rural du bois-énergie est un facteur d'attractivité plus important que la distance à Bamako. Cette caractéristique de l'échange est négligée dans la plupart des modèles de localisation existants qui, en majorité, s'attachent au seul coût du transport. Le modèle ainsi élaboré, par sa capacité de prédiction des flux et de mesure des potentiels, offre également un intérêt pratique pour la planification d'actions, équitables et efficaces, visant à rendre l'approvisionnement de Bamako plus durable

Available in PDF, EPUB and Kindle. Book excerpt: The conference "Combating Desertification with Plants" was held in Beer Sheva, Israel, from November 2-5, 1999, and was attended by 70 participants from 30 countries and/or international organisations. Desertification - the degradation of soils in drylands - is a phenomenon occurring in scores of countries around the globe. The number of people (in semiarid regions) affected by the steady decline in the productivity of their lands is in the hundred millions. The measures required to halt and reverse the process of desertification fall into many categories - policy, institutional, sociological-anthropological, and technical. Although technical "solutions" are not currently in vogue, the conference organizers felt that perhaps the pendulum had swung too far in the direction of "participatory approaches." Hence IPALAC - The International Program for Arid Land Crops - whose function is to serve as a catalyst for optimizing the contribution of plant germplasm to sustainable development in desertification-prone regions - felt the time was opportune for providing a platform for projects where the "plant-driven" approach to development finds expression. Some 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and Mechanisms of Plant Transfer. The conference was funded by UNESCO (Division of Ecological Sciences), the Ministry of Foreign Affairs of Finland, and MASHAV, Israel's Center for International Development Cooperation.

Book excerpt: Niger is sand, light, and heat. Starting from the necessity of the Mission Catholique du Dosso, which has worked in Niger for several years, this book speaks about the Nigerien situation which is characterized by a countrywide spread of poverty. Along with studying the country’s environmental, geographical conditions, the book discusses raw earth architecture in both vernacular and contemporary contexts. A number of the most common techniques are described. The possibilities for these methods to adapt to the contemporary language of architecture without losing the technical and physical benefits inherent in them are illustrated. The book embraces some topics that are not common but highly relevant in the Developing World, such as identity through the evolution of architecture and the value of transmitting knowledge related to the vernacular building process. Nowadays, Niger’s condition is characterized by a lack of resources, both physical and cultural. Earthen technology appears to be a valid solution in this situation for the creation of an environmentally sustainable approach. The book aims to provide an overview of the possibility of constructing new buildings related to the climate and traditional context, applying vernacular technology and solutions in a contemporary application. Providing a balance between teaching vernacular knowledge and the contemporary architectural language could help face this out-of-resource situation, aiming to get comfortable and affordable living spaces.

Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."

Available in PDF, EPUB and Kindle. Book excerpt: "L'Afrique est confrontée à deux défis majeurs liés à l'augmentation extrêmement rapide de sa population : Comment fournir des aliments en quantités toujours plus abondantes et comment approvisionner ces populations en énergie nécessaire en particulier à la cuisson des aliments ? Ces enjeux dépassent largement le seul continent africain. D'une part, cela suppose d'agrandir les surfaces agricoles, souvent aux dépens de la forêt dont les sols sont les plus fertiles. D'autre part, le bois provenant de ces défriches agricoles est utilisé comme bois de feu ou transformé en charbon de bois. Avec le très fort accroissement des populations à nourrir, les jachères ne sont plus aussi longues, la terre s'appauvrit et le bois est de plus en plus rare : il faut aller toujours plus loin de la ville tentaculaire pour chercher nourriture et bois - énergie. Soutenu par l'Union européenne, le projet Makala " Gérer durablement la ressource bois - énergie en Afrique centrale " a été entrepris pour comprendre et quantifier ce problème et proposer des solutions afin d'enrayer le cycle infernal de la dégradation de l'environnement et la difficulté d'approvisionnement en énergie domestique. Les résultats de ce projet réalisé de 2009 à 2013, à Kinshasa et à Kinsangani en République démocratique du Congo et à Brazzaville en République du Congo, constituent le coeur de cet ouvrage. Sont présentés tout d'abord l'état de la consommation en bois - énergie des grandes villes, particulièrement le bassin d'approvisionnement de Kinshasa, puis des outils indispensables à une bonne gestion de la ressource en bois, donc utiles à la gestion des arbres et de la forêt. Ensuite, sont proposés les modèles de gestion de cette ressource élaborés dans le cadre de ce projet. Enfin, les auteurs élaborent des perspectives d'avenir et des pistes de réflexions afin d'apporter des réponses aux besoins en alimentation et en ressources en bois - énergie dans ces régions dans une optique de développement durable."
