In Africa, the rate of change of burned area on the continent as a whole ranged from a non-statistically significant -0.45% yr1 in the period 2002-2016  to a significant -1.9% yr1 in the period 2001-2016 . These decreases coincided with areas of agricultural expansion or areas where drought reduced fuel loads . It is possible, however, that the 500-m spatial resolution of Modis remote-sensing fire data underestimates the area burned in Africa by half, by missing small fires . In the Serengeti-Mara savanna of east Africa, burned area showed no significant change from 2001 to 2014, although an increase in domestic livestock would tend to reduce the grass cover that fuels savanna fires .
