    Fire and Smoke

    Hundreds of fires were burning across Western Africa in early December
    2022. The Moderate Resolution Imaging Spectroradiometer (MODIS) on
    board NASA’s Aqua satellite acquired a true-colored image of clouds,
    smoke, and fire across several countries lying on the coast of Guinea
    on December 7.

    Each red “hot spot” marks an area where the thermal bands on the MODIS
    instrument detected high temperatures typical of actively burning fire.
    The largest cluster of fires lie in Ghana, a country slightly smaller
    than the size of the U.S. state of Oregon. Fire also can be seen in
    Cote d'Ivoire, to the west of Ghana, as well as Togo and Benin, two
    countries to the east of Ghana. Further west, few fires are visible in
    Nigeria. few fires are also seen in Burkina Faso, in the northwest or
    Niger, located in the northeast. A smokey haze covers the landscape
    over the visible hot spots and northward, while clouds likely obscure
    many hot spots from view.

    While it is not possible to discern the cause of a fire from satellite
    imagery, the time of year, location, and number of the fires strongly
    suggest that these fires are agricultural in origin. Most farmers in
    Ghana and nearby countries have small holding and still use traditional
    practices, such as fire, to manage land. Fires are used to clear
    stubble from old crops, to renew pasture, to open new land for cropping
    or pasture, or to prepare for planting.
