Is closing the agricultural yield gap a “risky” endeavor? por Gatti, Nicolas, Cecil, Michael, Baylis, Kathy, Estes, Lyndon, Blekking, Jordan, Heckelei, Thomas, Vergopolan, Noemi, Evans, Tom

“…SIGNIFICANCE: The risk-related yield gap is only expected to increase with weather extremes driven by climate change. Promoting “one-size-fits all” solutions to closing the yield gap could underestimate the effect of risk mitigation on agricultural production while increasing farmers.…”
