Book Description
La presente recherche conduite dans le bassin versant de Yakouta est une contribution pour expliquer comment les producteurs saheliens s'adaptent au changement climatique qui menace l'efficacite de leurs systemes de production. Les donnees d'analysees provenaient de la meteorologie nationale, des enquetes socioeconomiques et la cartographie classique ou des releves de terrain. Les resultats indiquent une forte variabilite temporelle de la pluviometrie, et une hausse de la temperature de 1961 a 2008. Cette situation a ete confirmee par les resultats des enquetes aupres des populations qui ont pour ce faire adopte des mesures palliatives. Leurs principales strategies sont le zai, les cordons pierreux, les bandes enherbees, la fumure organique, le paillage, les puits, les puisards, les forages, les bouli, les barrages, les mares. La determination de leur efficacite par Analyse multicritere a mis en evidence un impact spatial de 11,34% de bonne gestion de l'eau en saison des pluies et 7,43% en saison seche. Ces resultats sont relativement faibles et traduisent le bas niveau des pratiques de strategies de gestion de l'eau mises en uvre par les populations.

Rainwater harvesting technologies in the Sahelian zone of West Africa and the potential for outscaling
Author: Barry, Boubacar
Publisher: IWMI
ISBN: 9290906847
Category : Water harvesting
Languages : en
Pages : 44
Book Description
In West Africa, especially in the Sahelian countries of Burkina Faso, Niger, Mali and Mauritania, erratic rainfall sequences within and between years has often led to a high uncertainty in rainfed crop production. Over the past three decades, severe food shortages attributed to drought have been frequently reported in several Sahelian countries, most of which are amongst the least developed of the world. Innovative and indigenous ways to achieve improved crop yields through integrated land and water management such as rainwater harvesting and soil water conservation have been successfully tested and, in some cases, adopted in West Africa. This paper highlights the successful interventions of improved indigenous rainwater harvesting/soil water conservation technologies such as Zaï or tassa, stone rows and half-moon in the Sahelian zones of West Africa over the past 10 years, and their contributions to enhancing food security and alleviating poverty. The potential for adoption of these technologies at the farm level and their outscaling to areas with similar agroecological zones are also discussed.

Les ailes du Sahel
Author: Le Zwarts
Publisher: BRILL
ISBN: 9004278125
Category : Science
Languages : en
Pages : 564
Book Description
'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."
