a–d Absolute changes and e–h normalized relative changes in forest metrics. \(\delta\)Cover, \(\delta\)PD, \(\delta\)Height, and \(\delta\)NPP denote differences in forest cover, patch density, height, and net primary productivity (NPP) between road areas and background references, respectively. Inset pie charts show the frequency of grid cells with positive (\(\uparrow\)) or negative (\(\downarrow\)) differences. Insets 1–4 (numbered in a) are zoomed-in examples illustrating road impacts: 1, South America; 2, Africa; 3, Asia; 4, Europe. Bar charts depict latitudinal variations across 3° latitude bins. Continental boundaries were obtained from Natural Earth (https://www.naturalearthdata.com/). Source data are provided as a Source Data file.
