               A fifth of the world’s people,
               more  than 1.2 billion, live in
               areas of  physical water
               scarcity, where  there is
               not enough water to  meet
               all demands.  A further 1.6
               billion  people live in areas
               experiencing     economic
               water    scarcity,   where
               the lack of investment in
               water or insufficient human
               capacity makes it impossible
               for authorities to satisfy the
               demand for water.

              Physical water scarcity:  More  than  75%  of  river  flows  are  allocated  to  agriculture,
            industries, or domestic purpose.
             Approaching physical water scarcity : More than 60% of river flows are allocated.
             Economic water scarcity Water resources are abundant relative to water use, with less
            than 25% of water from rivers withdrawn for human purpose, but malnutrition exists.  What makes the desert beautiful is
              Little or no water scarcity : Abundant water resources relative to use. Less than 25% of   that some where it hides a well.
            water from rivers is withdrawn for human purposes.
