Climate Change Implications and Use of Early Warning Systems for Global Dust Storms - Reducing Disaster: Early Warning Systems for Climate Change - page 150

Fig. 8.2 A dust storm occurred on 29 July 2012 near Laguna Mar Chiquita due to low lake levels and
exposed, dried out sediment (NASA MODIS Aqua image, NASA 2012 ; visualisation by author)
regional contributor (Goudie 2009 ). Other dust-producing regions include the
Middle East, the Taklamakan Desert in northwest China, southwest Asia, central/
western Australia, the Etosha and Mkgadikgadi basins of southern Africa, the Salar
de Uyuni (Bolivia) and the southwestern United States (NRL 2009 ; Washington
et al. 2003 ; Shao et al. 2011 ). These dust-producing regions have minimal moisture
saturation, as indicated by a high erodible fraction value 2 (Fig. 8.3 ).
2 Erodible fraction value refl ects land cover type and associated wetness.
