Extended Data Fig. 1: Historical trends of yield and harvested area for soybean and second-crop maize in Brazil.
From: Protecting the Amazon forest and reducing global warming via agricultural intensification
Fitted models are shown in (a) and (b), but not in (c) to avoid overlapping. Slopes of the fitted linear regression models are shown. Slopes were statistically different from zero in all cases as evaluated using double-tailed, t-tests: P < 0.0001 for all slopes in (a) and (b) and P = 0.0075 (Amazon), P = 0.0113 (Cerrado), and P = 0.0057 (A. Forest) for slopes in panel (c). Data on yield and crop area was retrieved from IGBE16.
