The origin of rice cultivation in the Lower Yangtze Region,China

About the former half of the sixth millennium bc (Kuahuqiao culture) settlement area expanded to alluvial lowlands in the lower Yangtze region, and during the fifth millennium bc (Hemudu culture), adaptation to the wetland settings established. Although older rice remains have been found in this area, it is safe to say that rice cultivation began during Kuahuqiao and Hemudu cultures. At the beginning, it was only a part of broad-spectrum production highly dependent on lacustrine resources, and it took another millennium to establish the ancient civilization (Liangzhu culture) based on rice cultivation.
