Millet cultivation in Central Asia: A response to Miller et al.

Abstract

In a recent special issue of The Holocene, Miller et al. review the evidence for the spread of millet ( Panicum miliaceum and Setaria italica) across Eurasia. Among their arguments, they contend that millet cultivation came to Eurasian regions with hot, dry summers when irrigation was introduced, as part of a region-wide shift toward agricultural intensification in the first millennium BC. This hypothesis seems to align with the pattern of agricultural change observed in the Khorezm oasis, a Central Asian polity of the first millennium BC and first millennium AD. While we wholeheartedly accept this hypothesis for its explanatory value regarding trends across Eurasia, in this paper we nevertheless suggest that the introduction of millet to Central Asia needs further explication. Specifically, we seek to address the underlying assumption that this introduction was predicated upon centrally organized, state-level land development, increased sedentism, and the rise of Mesopotamian-style social complexity. We describe how millet cultivation in Khorezm was preceded by multi-resource strategies that included the cultivation of summer crops, and emphasize that this earlier history mattered significantly to the evolution of Khorezmian society and agriculture in the first millennium BC. In contrast to the imperial systems of West Asia, in Khorezm the introduction of complex irrigation works supported the expansion and greater stratification of pre-existing agropastoral lifeways, and helped to buttress the rise of nomadic elites within an agrarian zone. We believe the example of Khorezm is important because it helps to explain the emergence of integrated mobile-sedentist societies in the first millennium AD in Central Asia as a result of agricultural change. It also provides cultural and historical context to the spread of millet cultivation in the first millennium BC, suggesting that this phenomenon had significantly different implications for societies across Eurasia.

Arboreal crops on the medieval Silk Road: Archaeobotanical studies at Tashbulak

“…; 8%), melons (3%), peaches (3%), and almonds (3%) [ 28 ]. Moving further west, Brite et al [ 29 ] brought together a list of Soviet-period (mostly 1960-1970s) mentions of domesticated crops in archaeological reports. They noted the presence of grapes, millet, and barley as far back as the fifth century B.C., and peaches, Russian olives ( Elaeagnus angustifolia ), and melons possibly appearing sometime between the fourth century B.C.…”

New AMS 14C dates track the arrival and spread of broomcorn millet cultivation and agricultural change in prehistoric Europe

“…In the wider context of the long-lasting 'trans-Eurasian exchange 20 of many different elements, including raw materials, technologies, objects, animals and diseases 64 , 124 , broomcorn millet documents the process of 'food globalisation' in the Old World 17 , 21 – 23 , 26 , 125 . Reconstructing the When and Where of broomcorn millet in Europe helps us to understand whether the crop arrived “with a bang” 126 or if it ‘trickled in’ over the millennia of archaeologically well-documented communication between the east and the west. Europe in the Middle and Late Bronze Age is a paragon of connectivity and intercultural influences, which were particularly intensive in the second half of the 2nd millennium bc .…”

“…and Spengler et al 80 have discussed the importance of these complex multi-cropping systems in the Pamir Mountains by the tail end of the second millennium BC. Archaeobotanical data have also been used to demonstrate an increased prevalence of water-demanding crops in southern Central Asia 79 , and more intensive irrigation systems may have existed from the Murghab Oasis 81 , to Khorezm 82 , and Semirechye 77 in the late first millennium BC. Wilkin et al 83 recently suggested that the introduction of millet and possibly cereal farming in Mongolia may have played a role in the development of more complex social systems there as well.…”
