The Bronze Age breadbasket
In the arid Surkhandarya Region of southern Uzbekistan, archaeological work has uncovered evidence of a sophisticated Bronze Age agricultural society. This civilization is part of the Bactria-Margiana Archaeological Complex (BMAC), also called the Oxus Civilization, which flourished in Central Asia from approximately 2300 to 1700 BCE. The people of the BMAC were not nomadic; they were settled farmers who constructed fortified settlements and engineered complex irrigation systems to cultivate the fertile river oases.
Within these archaeological contexts, scientists have found caches of carbonized, or charred, plant matter. Accidental fires that might have destroyed a meal or a winter's grain storage instead created a perfect time capsule. The intense heat burned off organic material susceptible to decay, leaving behind pure carbon copies of ancient seeds. Among these remains are the staple crops that fueled the Oxus Civilization: wheat (Triticum) and barley (Hordeum). These perfectly preserved specimens show the food systems of a society that existed over 4,000 years ago.
