How does double-cropping increase farm production in Anhui province?

Double-cropping increases farm production in Anhui by allowing farmers to grow two crops on the same land within a single year. This practice maximizes the utility of available agricultural land, which is particularly significant in the wetter Yangtze valley where most land is devoted to rice cultivation.1

The expansion of this practice has been supported by significant improvements in irrigation and water conservancy measures implemented since the 1950s. By better utilizing water resources, the province has been able to increase the amount of land capable of supporting multiple harvests, thereby improving overall yields and per capita farm income. Additionally, farmers often utilize crop rotation, such as planting soybeans in the north in rotation with wheat or barley, to further optimize land productivity.213
