Why Farmland is Abandoned:
As groundwater pumping increased, water tables dropped, requiring pumping from deeper levels and at greater costs. Because of the increased cost, irrigation became prohibitively expensive. Farms thus were abandoned as unprofitable, especially in Cochise and Pinal counties.
China's "one child" policy of the late-1900s applied MOSTLY to rural areas. The one-child policy was a population control policy of China. It began during 1978 until 2015 where it was formally phased out. It was strictly enforced at the provincial level.
