Soil erosion decreases soil productivity and threats global food security. Various relationships between crop yield and soil erosion were found for different regions, but a comprehensive global synthesis of the relationship is lacking. To quantify crop yield and soil erosion, we conducted a meta-analysis with a hierarchical mixed-effects model based on global-scale studies, and incorporating erosion depth, crop yield, grain type, soil type, measure, and other factors. The results confirmed thatdoi:10.22541/au.158221375.54116578 fatcat:stpso42co5dshlylneiiepfcvm
