History of agriculture [SEP] Ancient China
Although the chain pump found use in public works of providing water for urban and palatial pipe systems, it was used largely to lift water from a lower to higher elevation in filling irrigation canals and channels for farmland. By the end of the Han dynasty in the late 2nd century, heavy ploughs had been developed with iron ploughshares and mouldboards. These slowly spread west, revolutionizing farming in Northern Europe by the 10th century. (Thomas Glick, however, argues for a development of the Chinese plough as late as the 9th century, implying its spread east from similar designs known in Italy by the 7th century.) Asian rice was domesticated 8,200–13,500 years ago in China, with a single genetic origin from the wild rice "Oryza rufipogon", in the Pearl River valley region of China.
