Increase in African dust flux at the onset of commercial agriculture in the Sahel region
Emissions of African dust increased sharply in the early 1970s, but the human contribution to land degradation and dust mobilization remains poorly understood. Now, a 3,200-year record of dust deposition off northwest Africa has been constructed. On the basis of this dust record and a proxy record for West African precipitation, it is suggested that human-induced dust emissions from the Sahel region have contributed to the atmospheric dust load for more than 200 years.
