A regulation-allocation coupling approach for agricultural water resources management based on water quantity orientation

In water-scarce areas with low grain yields, people have to expand the farmland scale to gain more food. Rapid expansion of agricultural scale may lead to a higher risk of re-abandonment of wasteland due to waterless irrigation in water-deficient areas. Against this background, this study proposed a...

Rapid expansion of agricultural scale may lead to a higher risk of re-abandonment of wasteland due to waterless irrigation in water-deficient areas. Against this background, this study proposed a water resources regulation-allocation coupling model.
