Extended Data Fig. 8: Global distribution of rice yield reduction and potential P pollution risk.
From: Reduced phosphorus availability in paddy soils under atmospheric CO2 enrichment
a, Global distribution of yield reduction risk level (1: extremely low, 2: low, 3: medium, 4: high, 5: extremely high; see Methods). b, Global distribution of potential P pollution risk level (0: no risk, 1: with potential environment risk). Note the size of the squares does not represent the actual area of rice paddy fields in Panels a and b.
