TL;DR: In this article, the authors used a large set of daily rain gauge data covering the Sahel (defined in this study as extending from 20°W−10°E and from 11°N−18°N) since 1950, combined with an unparalleled 5 minute rainfall observations available since 1990 over the AMMA-CATCH Niger observatory.

TL;DR: In this paper, the authors reviewed and synthesized the literature on the drivers of these paradoxical behaviors, focusing on recent works in the West African Sahelo/Sudanian strip, and upscaling the hydrological processes through an analysis of recent data from two representative areas of this region.

TL;DR: In this article, the authors analyse les dossiers de 323 patients porteurs de syndromes drepanocytaires majeurs, suivis a l'hopital d'enfants Albert-Royer de Dakar.

TL;DR: In this article, a bootstrap approach is proposed to compute the uncertainty associated with the estimation of these four parameters and of the related rainfall return levels for durations ranging from 1 to 24'h.

TL;DR: It is likely that a large part of the anemia observed in young children is due to iron deficiency, although further research is needed to confirm this and fully justifies the nationwide programs of iron fortification of flour, currently undergoing in most countries of French-speaking Africa.
