Dozens of fires were burning in the western Africa country of Guinea(center) on April 27, 2004. This image of the fires was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aquasatellite. Red dots show the location of active fires detected by MODIS. Guinea is approaching the end of its dry season(December-May), when dry, dusty winds blow across the country from the Sahara Desert out toward the Atlantic. These winds are known as harmattanwinds, and they can fan the flames of brush and agricultural fires, creating naturalhazards.

Though some fires are burning in the coastal regions, most are concentrated in the Fouta Djallon Highlands in the central part of the country, the countrys agricultural heart.
The widespread nature of the fires and the time of year suggests these fires are being set intentionally for agricultural purposes like pasture and farmland clearing. Though not necessarily immediately hazardous, such burning can have a strong impact on climate, weather, human health, and natural resources.
