| 英文摘要 | Climate change is intensifying the frequency and severity of droughts, posing a significant threat to global crop production. Accurately quantifying drought impacts is challenging and critical for mitigation. Here, we use a high-resolution, bottom-up assessment framework to analyze drought impacts on yields of four major crops-maize, soybean, rice, and wheat-at county, provincial, and national levels over 1997-2021. Results show yield losses escalate dramatically with spatial granularity, from 3.3% at the national level to 10.8% at the county level, with soybeans (16.3%) and maize (11.4%) being the most vulnerable. Despite an increase in drought frequency, drought-induced crop losses declined significantly, owing to the improvements in irrigation. Notably, a 10% increase in agricultural water use was significantly associated with a 1.71% reduction in yield losses. Our findings not only highlight the critical importance of scale-dependent risk assessments but also provide robust evidence and spatial pattern for the significant role of irrigation in mitigating drought risks. |
