In Brazil's Pantanal, the vegetation compacted under the marshy floodwater during the wet season dries out as ponds and lagoons evaporate, leaving flammable deposits underground that can continue to smolder long after visible flames die down. Like in the Amazon region, the Pantanal is also threatened by land grabbing for cattle pastures and soy cultivation.
