Sensitivity and uncertainty propagation in coupled models for assessing smallholder farmer food security in the Olifants River Basin, South Africa
Farm family balance sensitivity and Monte Carlo uncertainty were investigated. Farm balance non-linearity to in-season rainfall is due to different crop yields. Farm food security complexity relates to climate, environment and crop management. Better investments returns were realised under supplemental irrigation. Family balance uncertainty (4254%) influences management and policy adoptions.
