Without dust to move nutrients around, much of the earth would be infertile - phosphorus
Gill, 1996
Reactivation of basins (as a result of anthropological disturbance) results in aeolian transport which has major impacts on health

Nield et al., 2015
Use of TLS in the Mkgadikgadik Basin, Botswana to show that surface changes considerably over weeks/months/a year.
