Public ISBD Titre : Dust in the sahel : cause of drought. Type de document : texte imprimé Auteurs : Macleod, N. H. Mention d'édition : Department of Biology, the American of Biology Editeur : Department of Biology, the American of Biology Année de publication : 1974 ISBN/ISSN/EAN : CI-04121 Note générale : Dust in the monsoonal atmosphere of the west African sahel may reduce rainful by (1) suppressing formation of rain-producing clouds, and (2) retarding the normal northward progress of the summer monsoon systems which bring rain to the sahel. The dusts can originate from soil surfaces denuded by overcroping and overgrazing. This condition is found by satellite to occur not only in the sahelian zone, but throughout west african. Revegetation through crop and range management can improve the surface conditions which now give rise to dusty sahelian skies. Sach a program is urgently recommended.
