With WORLD WATER DAY 2012 just around the corner (March 22, 2012), how much do doctors, nurses and other health professionals know about water?

Here are “25 Facts Every Health Professional Should Know About Water”:

2. Oceans, surface water and ground water are interconnected and interdependent.
3. Most of the Earth’s water (99%+) is not fresh, not accessible, or neither fresh nor accessible.
4. Humans need 2.3 liters of water on average per day to survive. Humans’ average daily diet however derives from an investment of 3,000 liters of water.
5. Agriculture is the leading consumer of water worldwide, consuming 70% of our fresh water.
6. Irrigated fields have 400% greater food yield than rain-fed fields. By 2030, 70% of the world’s grain crop will come from irrigated fields.
7. Currently 27% of fish consumed by humans is “grown” through aquaculture. China alone is responsible for 70% of the “crop.”
8. Industry is the second leading consumer of fresh water, consuming 22% of our total supply worldwide.
9. Water is essential for all forms of energy generation worldwide.
10. Global hydropower currently provides about 20% of our energy worldwide.
11. Supplies of safe, fresh water are declining and global population is increasing. In the past 100 years our population has tripled, and water consumption has increased six-fold.
12. Water scarcity is increasingly common. 3.4 billion global citizens will live in water-scarce areas by 2025.

21. Water-related disasters between 1990 and 2000 claimed over half a million lives. Most could have been prevented by Integrated Water Resource Management and Disaster Preparedness.
22. Global warming is a significant contributor to water scarcity and water disasters.
23. Integrated Water Resource Management (IWRM) is organized at the catchment level, proactively balancing infrastructure development, allocations of water and mitigation of risk.
24. IWRM has social, political and economic dimensions that directly impact human health, poverty levels and gender equality.
