Dust occurs mainly during the dry season, either locally or transported, with a peak between February and May • main sources are from Mauritania/ Algeria and the Bodele depression • impacts on transport through reduced visibility • impacts on health (meningitis, respiratory diseases, flu, eye infections) • impacts on agriculture through land degradation 2nd training course on WMO SDS-WAS, Antalya, 21-25 Nov. 2011
