Disadvantages of irrigation

  • A lot of water stored in the reservoirs and water channels is lost through evaporation. Over time the water table drops and eventually the store of water in the ground runs out, turning the land into desert.
  • Some rivers have almost no water reaching the sea. This can reduce the area of fertile delta land and increase salination at the river mouth, which upsets the local ecology.
