Short summary
Climate change is increasing compound disasters in China, where drought and extreme rainfall strike within five days. These events peak in summer, especially in the northwest, southwest. From 2000–2019, maize had the generally highest exposure risk, rice the lowest. Using soil moisture and rainfall data, the study links event frequency with crop areas, showing major threats to food security and guiding better disaster planning.
