- Today, 6.8 billion people inhabit the world
- One billion people worldwide lack access to clean drinking water
- Three billion more live in water-scarce regions
- Many key rivers, aquifers, wells and lakes around the world are drying up
Trends that Increase Water Scarcity
- Growth in the world’s population and increased urbanization: Increased population and urbanization (both of which are expected to continue), and the failure of governments to instill a sense of urgency for water conservation practices, have led to overuse of natural water systems.
- Global weather patterns: Increased droughts are having a dramatic effect on municipal water systems that rely on surface-based water sources.
- Competition for water resources: Water demands for other uses (agricultural, industrial) reduce available supplies for drinking water.
