Over-grazing

• Desertification =
  • is processes that reduce the quality of land.
• Degraded =
  • when land is worn down, bad condition.

Effects of overgrazing 

• Plants don’t have enough time to grow
• Bare patches of soil appear
• Weeds and alien plants replace grass
• Soil is eroded by wind and water.
• Dams begin to fill with washed away soil
• Animals start eating alien plants 
• Animals then become sick because the alien plants don’t contain enough nutrias
• Weak animals (less offspring’s)
• Animal productivity decreases 
• Young animals need more grass = more overgrazing 
• Desertification takes place
• The land is no longer useful
• People leave the land.

Overgrazing has a huge effect on the environment and people.

Sustainable grazing 

• Fodder =
  • food for animals
• Silage =
  • animal fodder stored in large tanks called silos.

Sustainable grazing methods - 

• Rotational grazing
