peer reviewedSince the late 1960s, the Sahel of West Africa is affected by a dramatic drought. Based on long-term daily datasets in four synoptic stations, this article analyses recent trends in the Eastern Niger rainfall regime from 1940 to 2007. Results suggest that the Sahelian drought ended in the early 1990s. However, several rainfall indices still present strong significant downwards trends. We also show that the length of the rainy season has not been heavily impacted, except in its amplitude, which may suggest an increasing degree of vulnerability.Depuis la fin des années 1960, la région sahélienne est touchée par une terrible sécheresse.
