Abstract The present paper aims to explore the relationship between the environmental changes produced in the Puna Seca Argentina during the period 12 000-4000 years BP and its incidence in the variability observed in the adaptive strategies developed by human groups in lithic technology. The lines of evidence used for the study of the paleoenvironment were mainly the pollen analyzes, and for the mobility it was used the technological analysis for the approach of supply of the different types of rocks. The results show that the Early Holocene was more stable and humid environment, with a smaller distance between patches of vegetation and those groups of hunter-gatherers developed a direct supply of certain raw materials and the rock-carving sequence was fully developed in the same residential base; while during the middle Holocene an environmental and technological variations are detected and the period were divided into two different moments, which is reflected in a higher specialization of the sites in relation to the different technological activities, accompanied by a growing aridity process. Likewise, an increase in the environmental variations in the second half of the middle Holocene is detected, which may have influenced the decision-making of human groups in relation to this risk factor.
