  abstract = {{T}o examine the climate of the mid-{H}olocene and early human settings in the {A}ndes when the {A}ltiplano was recording the most arid phase of the {H}olocene, we analyzed plant-related proxies (pollen, phytoliths, diatoms, stable isotopes) from a sediment core sampled at high elevation in the {E}astern {C}ordillera of {B}olivia. {O}ur study was carried out in the wetland of {T}iquimani (16 degrees 1206.8{S}; 68 degrees 351.5{W}; 3760 m), on a well-known pathway between {A}mazonia and {A}ltiplano. {T}he 7000-year old record shows a two-step mid-{H}olocene with a dry climate between 6800 and 5800, followed by a wetter period that lasted until 3200 cal. yr {BP}. {I}n the {C}entral {A}ndes of {B}olivia, a widespread aridity was observed on the {A}ltiplano during the mid-{H}olocene. {H}owever, here, we show that moisture was maintained locally by convective activity from the {A}mazon lowlands. {D}uring the arid interval between 5000 and 4000 yr {BP}, these niches of moisture produced specific grasslands that may have enabled the survival of an archaic culture of hunter-gatherers on the {P}una. {T}his development occurred 2000 years before expansion of quinoa cultivation on the {P}una.},
