Fig. 4: Resilience of the quasi-decentralized system to droughts under different climate conditions.

a Irrigation self-sufficiency for the growing season scale with various aridity index; b Irrigation self-sufficiency for the irrigation event scale with various no-rain days before irrigation. The edge histograms show the distribution of climate conditions and irrigation self-sufficiency. The center plots show the relationship between system irrigation self-sufficiency and the climate conditions, the dots represent all different cases and the lines are the mean values for specific climate conditions.
