The fires are scattered across southern Tanzania and northern Mozambique, places where the peak seasonal burning typically occurs in September or October. African savanna fires are mostly caused by humans for agricultural activities such as clearing pasture or cropland or driving game. Although the fires are not necessarily immediately hazardous, the frequency and wide extent of the burning can have strong influence on weather, climate, human health, and natural resources.
