| Summary: | <p dir="ltr">Global food security relies on the resilience of dominant crops to intensifying climate extremes. Conservation agriculture (CA), integrating minimal tillage, permanent soil cover, and crop diversification, is widely advocated as a climate-smart strategy, yet global, data-driven evidence for its effectiveness in strengthening crop yield resilience under climate extremes is lacking. We synthesized 7,350 yield records of eight staple crops from 397 long-term experiments to assess <a href="" target="_blank">whether CA enhances global crop yields and their temporal stability by providing resistance during, and recovery after, extreme climate events.</a> Complete CA systems, adopting all three principles simultaneously, increased both mean yield and interannual stability during climate events, whereas partial adoption reduced stability and amplified historical yield losses. Contrary to prevailing assumptions, CA provided limited resistance during extremes but substantially enhanced recovery afterward, especially following drought. Crop type and adoption duration play a central role in building CA’s resilience. Long-term (>15 years) and crop-tailored implementation of complete CA systems delivers enduring gains in yield stability, food security, and climate resilience, establishing a foundation for adaptation to future climate extremes.</p> |
