Vulnerability assessment of agricultural production systems to drought stresses using robustness measures

Abstract Intensification of droughts in agricultural areas threaten global food security. The impacts of drought stresses vary widely across a region, not only due to climate variability but also due to heterogeneous soil and groundwater buffering capacities which protect against droughts.
