Wind born sediment also transports billions of tons annually, most prominent in Saharan dust, but thought to be substantially less than rivers; again, variance of year to year and human impacts of land use remain unquantified on this data.
Wind-borne sediment, particularly Saharan dust, plays a significant role in transporting large quantities of material annually.  However, its magnitude is compared to river transport, which remains uncertain due to the influence of yearly variations and human impacts on land use.
