During the Holocene, man's challenges with climate entered a new phase. Holocene climatic cycles, by creatingdry events, have imposed many subsistence tensions on water-dependent communities. The semi-arid and aridregion of North Central Iran, which has been very vulnerable to any climate change, experienced unfavorableenvironmental conditions during these climatic events. So far, only a handful of Early Holocene rural settlementshave been found in the region, possibly because of the mostly arid climate of the period. In general, the firstevidence of Neolithic villages in North Central Iran dates back to the beginning of the Middle Holocene, afterthe 8.2 ka BP event. The first cultural flourishing of this region can be seen from the last quarter of the sixthmillennium BCE. Each cultural flourishing period seems to have declined for some time with the occurrence ofa dry event. The effects of climatic tensions on human societies in North Central Iran have been found around6500-6000, 5700-5400, 5000-4700, 4300-4000, and 3300-2700 BCE. According to data analysis, the frequency ofsettlements and the trend of cultural progress gradually peaked from the early sixth millennium to the mid-fourthmillennium BC, but in the second half of the latter millennium, a gradual decline began which led to the BronzeAge collapse in ca. 2700 BCE. This event probably occurred due to the drop in temperature and the increase in thefrequency and severity of aridity in the transition phase to the Late Holocene.
