Fig. 5: Sensitivity of soil carbon to changes in fire frequencies across savannah–grasslands globally.
From: Soil carbon storage capacity of drylands under altered fire regimes
Upscaling our analysis to savannah–grasslands worldwide across the distribution of the areas where our model predicted a change in SOC under observed trends in burned area. a, Predicted gain in soil C in areas with declining fire frequency, with a positive % illustrating a gain in soil C under the new fire regime. b, Predicted change in soil C with higher fire frequency, with a negative percentage illustrating a loss in soil C in the frequently burned. We estimated changes only in areas within environmental conditions used in our training model. Coverage of environmental variables is illustrated in Extended Data Fig. 8, and trends in burned area are illustrated in Extended Data Fig. 9.
