Rainfall Disturbances in the Context of Climate Change in the Diéma Circle, Mali

The evolution of rainfall is of great concern to Sahelian countries and particularly Mali. Thus, this research focuses on the analysis of rainfall disturbances in the context of climate change in the Diéma circle. To do this, a mixed methodological approach was used involving the collection of quantitative and qualitative data. The results show that rainfall has changed significantly over the last 60 years in the Diéma circle. This evolution is illustrated by a large fluctuation in annual rainfall amounts with a break detected in the rainfall series and by a poor spatio-temporal distribution of rainfall marked by the recurrence of dry sequences. It is also marked by a trend towards shortening the duration of rainy seasons from 1960 to 2019. These rainfall disturbances in the Diéma circle are a sign of climate change.
