Human Responses to Climatic Variation in the Namib Desert During the Last 1,000 Years

Abstract

Radiocarbon dates for camelthorn trees in the Namib Desert reflect marked variation in rainfall during the last 1,000 years. These records and other proxy climate data indicate a loose teleconnection with the southern African climatic record, especially for regionwide episodes of dry conditions resulting from extreme El Niño events. However, archaeological evidence of hunter-gatherer and nomadic pastoralist occupation does not mirror the climate record by indicating that the desert was only inhabited during periods of favourable rainfall. It points instead to a specialized strategy which allowed continuous occupation of the Namib Desert despite extreme fluctuations in rainfall, by combining the use of primary resource areas with opportunistic use of secondary, ephemeral resources in an alternating density-dependent and density-independent dynamic.

Résumé

Des datations radiocarbone effectuées sur les arbres camelthorn dans le Désert du Namib soulignent des variations marquées du taux de précipitation au cours des milles dernières années. Ces datations, ainsi que d’autres données relatives au climat, sont globalement cohérentes avec l’enregistrement climatique de l’Afrique australe, en particulier avec les épisodes interrégionaux de sécheresse dus aux évènements El Niño. Toutefois, les vestiges archéologiques des occupations de chasseurs-cueilleurs et de pasteurs nomades ne s’accordent pas avec les données climatiques en indiquant une fréquentation du Désert limitée aux périodes de pluie plus favorables. Ils démontrent au contraire une stratégie spécialisée permettant l’occupation continue du Désert du Namib, malgré les fluctuations extrêmes des précipitations. Cela est rendu possible grâce à l’exploitation combinée de zones de ressources primaires et à l’exploitation opportuniste de ressources secondaires éphémères, selon une dynamique alternant dépendance ou indépendance à la densité des ressources disponibles.
