Agricultural Fires in Indochina (IMAGE) NASA/Goddard Space Flight Center Caption The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite collected this natural-color image which detected dozens of fires burning in Indochina on Feb. 2, 2015. The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality. Credit NASA image courtesy Jeff Schmaltz, MODIS Rapid Response Team.
