Key Info
  • Desertification and climate change
  • Duration: 02:18
  • The cumulative cause of desertification is outlined. The cycle begins when vegetation is removed. This vegetation would normally hold moisture, which evaporates into the atmosphere due to the warm climate. The evaporated moisture condenses to form clouds and rainfall normally occurs in the afternoons. If the vegetation is removed, the soil becomes drier and there is less moisture available for evaporation. Rainfall decreases and dry soil can easily be blown away.
