Cambios Paleoclimáticos Y Su Influencia Sobre El Desarrollo Cultural En El Sur Del Área Central Andina
Year: 2017
Type: article
Abstract: Until recently, the environmental history of the entire Central Andes was thought to be uniform. New insights about cultural dynamics show a recurrent pattern of boom and decline, coincident to regional changes in environmental favorability, which was out-of-phase. Remote palaeoclimatic proxy data from the tropics showthat these changes were triggered by ENSO variability. El Nino-like conditions and an enhanced South American Summer Monsoon (SASM) led to moisture transport to the Titicaca region, whereas La Nina-like conditions and a weak SASM were the prerequisites for drought around lake Titicaca and enhancedrainfall in the Palpa-Laramate region further north, supporting its lowland oases. This seesaw occurred several times since the Mid-Holocene, pointing to a general underlying mechanism of regional impacts of the superimposed ENSO system.
