A Nature Communications study from Aalto University finds that large-scale climate oscillations, including El Niño-Southern Oscillation, the North Atlantic Oscillation and the Indian Ocean Dipole, affect up to two-thirds of the world's cropland. The researchers say improved forecasting could help agricultural planning.
The findings reinforce that ENSO and related cycles drive yield variability in corn, soy, rice and wheat, which supports risk premiums when forecasts shift, but the study itself does not signal an immediate supply change.
After 445 past neutral weather events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.6%), and +0.7% over 20.
After 324 past neutral weather events, Soybeans moved a median +0.0% over 5 sessions (52% higher; middle half -1.4% to +1.7%), and +0.7% over 20.
After 224 past neutral weather events, Wheat (SRW) moved a median -0.1% over 5 sessions (46% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
After 31 past neutral weather events, Rough Rice moved a median -0.0% over 5 sessions (48% higher; middle half -2.1% to +2.1%), and -1.5% over 20.
