March 15, 2006—World leaders gather in Mexico City for the Fourth World Water Forum, March 16 – 22, to tackle an increasingly urgent problem—the growing number of people without enough water resources, nor access to clean water or to basic sanitation.
Consider these projections:
In 1995, some 436 million people in 29 countries lived in places where the water supply was scarce or under stress. By 2025, more than 1.4 billion people in 48 countries are expected to be in the same position. By 2035, the number is expected to grow to three billion, according to the World Bank.
Despite improvements over the last 20 years, 1.1 billion still lack access to water supply and 600 million lack sanitation.
