Other claims from this paper (8)
- Method / resource APSIM realistically simulated farm-scale grape yields.
- Observation Western Cape experienced several severe droughts over recent decades.
- Association Severe droughts coincided with lower rainfall and higher temperature.
- Association Most severe Western Cape droughts occurred in El Niño years.
- Association At district scale, drought index and grape yield were weakly correlated (r≈−0.5).
- Association At farm scale, drought index and grape yield were strongly correlated (r≈−0.9).
- Association Poor farm-scale grape yield years coincided with moderate or severe drought periods.
- Mechanism Authors infer that irrigation management mitigates drought impacts on grape yields.
