Although water stress exists in the United States and Mexico
and along the western coast of South America, the
world’s major belt of water stress lies across northern
Africa, the Middle East, central and southern Asia, and
northern China. These stresses are increasing because
this is also the zone of the largest projected population
growth during the next 15-20 years.
In some of these regions, water-from-air systems may be suitable for improving local drinking water availability. Tools such as water-from-air resource charts can assist in efficient deployment of water-from-air systems (atmospheric water generators).
