Madagascar’s famine has been exacerbated by events of this type known as tiomena which gain their characteristic red (-5[1])tint from iron-rich laterite. Outbreaks of meningococcal meningitis in its namesake “belt” correlate with increased instances of these events during the Harmattan. The Bodélé Depression of Lake Chad feeds many of these events whose simoom variety can overwhelm the sweating response causing (15[2])sudden (*) heatstroke.

Pneumonia (-5[1])and (-5[2])silicosis may result (-5[1])from (-5[1])excessive exposure to these events which, in Africa, provide enriching (-5[1])nutrients to the Amazon Basin.
