Available in PDF, EPUB and Kindle. Book excerpt: Quiconque a séjourné au Sahara/Sahel aura pu prendre la mesure de l'importance de l'eau dans la vie des populations du nord-ouest de l'Afrique, qu'elles évoluent en milieu urbain ou en milieu rural. L'eau structure les modes de vie, les itinéraires de nomadisme, les choix de sédentarisation, l'habitat. La Mauritanie constitue un laboratoire privilégié pour appréhender les enjeux autour de la ressource hydrique, de sa gestion et des multiples risques auxquels elle est aujourd'hui exposée. Ce double numéro, hommage à Pierre Bonte, est le fruit d'un colloque tenu à l'Université de Nouakchott en mai 2018. Si l'essentiel des contributions porte sur la Mauritanie et la Vallée du fleuve Sénégal, les lecteurs trouvent des points de comparaison avec les montagnes de l'Atlas marocain, le Sahara algérien et le Nord Soudan.

This book was released on 2021-07-22 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Publication combines results obtained by interdisciplinary groups from numerous academic institutions working on Paleoproterozoic formations to decipher the origins of the main mineralization resources in the West African Craton (WAC) and their impacts on African economic development. Structural, geophysical, sedimentological, stratigraphical, geochemical, petrophysical and mineralogical analyses have been used to highlight the complexities involved in mineralization emplacement and its origin and evolution within the WAC. Fourteen articles contribute to new knowledge in mineral research. They show that the geodynamic evolution of the WAC is complex from one area to another: it involves subduction, collision and obduction during several deformation phases ranging from Birimian (2.3–2.0 Ga) to Pan-African (650–450 Ma) events. Various modelling techniques, when integrated, help in understanding the mechanisms of mineralization emplacement, some of which are still a matter of debate. The challenge for further studies is mitigation for sustainable development that can be appropriately used to minimize such damage.

Book excerpt: Rapid growth, unmanageable cities, urban crisis, macrocephali... The cities of west Africa are no longer ‘plannable’ – at least not using traditional urban development tools. Without negating the importance of participatory processes in city creation, it nonetheless seems crucial to return to city plans and models, to what cities convey, and how they are built. But to understand the city in all its depth and richness, we must also hit the streets. The West African City proposes a dual perspective. At the urban scale, it analyses historical trajectories, spatial development, and urban planning documents to highlight the major trends beyond the plans. At the second level – that of public space – the street is discussed as the city’s lifeblood. By innovating approaches and testing new methods, The West African City offers an unconventional look at Nouakchott, Dakar and Abidjan, the three study sites for this investigation. The city of today, in Africa or elsewhere, must re-examine its many social, economic, cultural, political, and spatial dimensions; for this, urban research has begun challenging its own methods. This book is also the companion of Chenal's MOOC African cities.

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."

This book was released on 2008-12-10 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.
