Das Projekt "Klimatische Veraenderungen im suedwestlichen Afrika (speziell Namibia): Verschiebung von Wuestengrenzen und Palaeomonsune (ICGP 349)" wird vom Umweltbundesamt gefördert und von Universität Stuttgart, Institut für Geographie durchgeführt. The phenomenon of shifting desert margins during Pleistocene and Holocene times shall be analysed on Namibian territory. The Eastern boarder of the Namib Desert as well as the Western part of the Kalahari, react on climatic fluctuations or changes (key-words: Paleomonsoon, Mega-ENSO events) by altering their ecosystems and geomorphodynamics. Following the todays ephemeral rivers from the Namibian highlands or Great Escarpment trough the Namib, fluvial deposits and eolian sediments are investigated with the aim to identify magnitude, frequency, duration and absolute age of climatic variations in arid and semiarid environments.
