      On February 13, 2023, many dozen fires were burning across Ethiopia and   
      South Sudan as heavy smoke sprawled over the region. The Moderate   
      Resolution Imaging Spectroradiometer (MODIS) on board NASA’s Aqua   
      satellite acquired a true-color image of the scene on that same day.   
      Each red “hot spot” marks an area where the thermal bands on the   
      instrument detected temperatures higher than background. When combined   
      with typical smoke—as in this image—such hot spots mark actively   
      burning fires.   
      
      While it’s not possible to know, for certain, the cause of a fire via   
      satellite imagery, the location, time of year, and number of fires   
      strongly suggest that these are agricultural fires—fires that are   
      deliberately set to manage lands. Agricultural fire serves a variety of   
      purposes. It is often used to open new savanna, grassland, or forest   
      into cropland or pasture. In established fields, fire is an easy tool   
      used to clear stubble and waste at the end of a growing season and to   
      return nutrients to the soil. Pastureland is sometimes renewed by   
      burning, as it clears the field of unwanted weeds and encourages fresh   
      growth of forage.   
      
      While fire is a commonly used tool in traditional agriculture, it can   
      produce tremendous amounts of smoke that can harm the health of both   
      human and animals. Fire may also slip out of control to create wildfire   
      that may damage large areas. Widespread use of fire in “slash-and-burn”   
      practices is a major factor in deforestation across the Earth.
