Abstract Arising from D. Renard & D. Tilman Nature (2019)

Stable agricultural systems are fundamental for the reliability of agricultural production and food security. Recently, Renard and Tilman1 reported that crop diversity, calculated as the exponential value of the Shannon diversity index of harvested areas of 176 crops, stabilizes national food production. Here we show that crop asynchrony—that is, asynchronous production trends between different crops2—is an even better predictor of agricultural production stability than is crop diversity. Our finding suggests that asynchrony is one important property that can explain why a higher crop diversity supports the stability of national food production, and that it should be considered in strategies to stabilize agricultural production through crop diversification.
