Water Scarcity in 2025
Physical water scarcity: these countries have not sufficient water resources for the needs in 2025
Economic water scarcity: this group has enough water resources, but only with regulations (more
supply than 1995, more than 25%)
No physical water shortage: no water scarcity, less water supplies than 25% of 1995
