Des cumuls de pluies globalement excédentaires et normaux sont respectivement attendus sur le Sahel Est et sur le Sahel Centre et Ouest, en juillet-Aout-Septembre 2024 ; Des dates de fin de saison tardives à normales et des séquences sèches longues dans la deuxième moitié de la saison sont attendues sur la bande sahélienne. Des écoulements globalement supérieurs aux moyennes sont attendus dans les principaux bassins fluviaux du Sahel.

Sahelian Africa faces a persistent problem of variability in rainfall, which is the major driver of vulnerability in the region. Populations in the Sahel are among the poorest and most vulnerable to climatic variability and land degradation. They depend heavily on healthy ecosystems for rainfed agriculture, fisheries, and livestock management to sustain their livelihoods. These constitute the primary sectors of employment in the region and they generate at least 40 percent of the gross domestic product (GDP) in most of the countries. Furthermore, ecosystem services provide much needed livelihood products, such as fuelwood and bushmeat, among others. Unfortunately, increasing population pressures on food, fodder, and fuelwood in a vulnerable environment have deteriorating impacts on natural resources, notably vegetation cover. Climate variability along with frequent droughts and poorly managed land and water resources (surface and underground) have caused rivers and lakes to dry up and contribute to increased soil erosion.
