    Dozens of fires burned across the southern coast of West Africa in late
    December 2021. The Moderate Resolution Imaging Spectroradiometer
    (MODIS) on board NASA’s Terra satellite captured a true-color image of
    the smoke-filled scene on December 23.

    Each red “hot spot” marks an area where the thermal bands on the MODIS
    instrument detected high temperatures. When combined with typical
    smoke, as in this image, such hot spots mark actively burning fire. The
    fires span five countries. From west to east they are Côte d'Ivoire,
    Ghana, Togo, Benin, and Nigeria. Most are clustered in Côte d'Ivoire
    and Ghana. Smoke covers the entire region and streamers of smoke pour
    across the Gulf of Guinea.

    The location, high number, and time of year strongly suggest that these
    are agricultural fires, which have been deliberately set to manage
    crops or pasture. The economy of many of these countries is dominated
    by agriculture, with high numbers of residents employed as farmers.
    Fires are used to clear stubble from harvested crops, prepare land for
    new crops, and to clear new land for pasture or cropping. They are also
    sometimes ignited to facilitate hunting, by driving game towards the
    hunters. On a small scale, the fires do not necessarily do serious
    harm, but large numbers of fire and smoke can cause respiratory
    problems in people and animals, damage air quality, and may even impact
    climate.
