How does the present dry spell in the Sahel compare with the other dry spells in the past?

The present dry spell in the Sahel has been severe and prolonged, with significant impacts on agriculture and food security. While the Sahel region has experienced dry spells in the past, the current dry spell is considered more intense and longer-lasting, partly due to climate change exacerbating the situation. The frequency and intensity of dry spells in the Sahel are likely to continue increasing if global efforts to address climate change are not significantly scaled up.
