I want to know the answer to the following question:
What did cultivation shift from to salt-tolerant barley during the Ur III phase?
All the background I'm provided with is that "During the Akkadian and Ur III phases, there was a shift from the cultivation of wheat to the more salt-tolerant barley, but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three fifths.". Is that enough to answer the question?
Answer: yes
