Figure 1 Relationships between Above-Ground Carbon Stock Density and Agricultural Yield in Three Farming Systems Relationships between above-ground carbon stock density and agricultural yield in three farming systems. Shaded areas show the bootstrapped 95% confidence intervals around estimates. See STAR Methods for details on yield and carbon stock estimation and modeling approach. See Figure S1 for separate curves fitted to different soil types in Poland and Figure S2 for the uncapped curve for Ghana. See also Table S1.

Figure 2 Schematic of Three Different Land-Use Strategies: Land Sharing Uses All Available Land at the Lowest Possible Yields Schematic of three different land-use strategies: land sharing uses all available land at the lowest possible yields; land sparing maximizes yields and conserves natural habitats; intermediate strategies use yields between these two extremes. All landscapes produce the same amount of food, with numbers representing the relative yields of different agricultural lands. We show a representative intermediate strategy but tested hundreds of strategies between land sharing and land sparing.

Figure 3 Projected Mean Above-Ground Carbon Stocks Averaged across Entire Study Regions under Different Land Use Strategies at Different Production Levels Projected mean above-ground carbon stocks averaged across entire study regions under different land use strategies at different production levels. Dark colors show projected stocks under projected 2050 production levels; intermediate colors show stocks under 2014 production levels; light colors show stocks with production at 50% of 2014 levels. We tested 148 possible intermediate strategies but show the results for when yields are halfway between those under land sharing and land sparing. Error bars show the bootstrapped 95% confidence intervals around estimates—see Quantification and Statistical Analysis in STAR Methods for details and Figures S3 and S4 for explanation as to why, despite the overlap of confidence intervals, we conclude that land sparing outperforms all other strategies.
