water tables are falling, lakes are shrinking, wetlands are disappearing ... Perhaps
the clearest signs of water scarcity is the increasing number of countries in which
population has surpassed the level that can be sustained comfortably by the
water available. As cl rule of thumb, hydrologists designate water-scarce coun-
tries as those with annual supplies of less than 1000 cubic meters per person.
Today, 26 countries, collectively home to 232 million people, fall into that cate-
gory. (Postel. 1992a: 2332)
