  1. In this table, a value of 0 means no land is available. In general, when ETA = 1, it shows that the average productivity of new land is equal to the average productivity of existing cropland. ETA values greater than 1 are also truncated to 1. aRows are AEZs from AEZ1 to AEZ18. bColumns R1 to R19 represent the following regions, respectively: USA, EU27, Brazil, Canada, Japan, China, India, C-America, S-America, E-Asia, Mala-Indo, R-SE-Asia, R-S-Asia, Russia, E-Europe-RFSU, Other Europe, M-East-N-Africa, Sub-Saharan Africa, Oceania. These regions and their members are listed in Additional file 1.
