  • Many parts of the world already suffer from a severe lack of water impacting on all forms of human development
  • Population growth and economic development are increasing the demand for fresh water
  • Climate change tends to reduce availability of potable water – either through increased likelihood of flooding (too much water) or increase likelihood of drought
  • A global water crisis is developing that particularly impacts on countries with largest populations
World demand for water is increasing while supplies are shrinking
