Distinguishing anthropogenic and natural contributions to coproduction of national crop yields globally

Abstract Crop production is a crucial ecosystem service that requires a combination of natural and anthropogenic contributions to high and stable yields, which is a coproduction process. We analysed this coproduction based on nationally aggregated data for 15 major crops for 67 countries and the Eur...
