Irrigation area, efficiency and water storage mediate the drought ...
2023年2月10日 · Days to Day Zero (DDZ) measures the resilience of irrigated agriculture to drought. Absorptive, adaptive, anticipative and transformative capacities can change DDZ. Improved irrigation efficiency and water storage can increase resilience and DDZ. But resilience and DDZ decline if efficiency and storage expand irrigated areas.
