      On November 28, 2022, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a remarkable   
      false-color image showing burn scars scattered southern Sudan and   
      northwestern South Sudan.   
      
      Most of the land visible belongs to South Sudan, including the wetlands   
      near the White Nile River and rich agricultural lands to the west of   
      the wetlands. To the north, the landscape of Sudan changes rapidly from   
      the green at the border with South Sudan to more arid land at the edge   
      of the Sahara Desert.   
      
      By using visible and near-infrared light (bands 7,2,1) burn scars –   
      which may appear black, brown, or brick red - stand out in stark   
      contrast to vegetation, which appears bright green. Open land appears   
      tan, deep water is colored deep blue and clouds, when present, may   
      appear either white or tinted with electric blue. The color variation   
      in burn scars depends on type of vegetation burned, the completeness of   
      the burn, the amount of residue remaining after the burn, and the age   
      of the burn. Fresh burn scars most often appear black or brick red,   
      while older scars, where vegetation has begun to regrow, become lighter   
      and eventually tinted with green.   
      
      In this image, burn scars are abundant across all of the bright green   
      (vegetated) areas, especially along the Sudan-South Sudan border, while   
      the vegetation near the darkly-colored waters of the White Nile and   
      associated wetlands show little scarring. The heavily-burned areas sit   
      in the location where traditional agriculture is practiced. Farmers in   
      this location have used fire to clear new land for fresh cropping, to   
      clear stubble from harvested fields in preparation for planting the   
      next crop, and to renew pasture for centuries. The multiple shades of   
      burn scars give evidence of fires burning in this area over many years.
