| Research Abstract |
This study assessed the reliability of the first global cropping prediction. Significant climate.crop relationships were found between the percentage changes in yield relative to that in the previous year and conditions of temperature and soil moisture level averaged over the 3-month period, commencing 3 months before harvesting and ending at harvesting. Using the derived statistical relationships and seasonal climatic forecasts, it is revealed that skillful within-season predictions of crop failures of wheat and rice are possible over approximately 20% of the global harvested area.
