Global water resources

Conclusion

  1. Globally, water use has increased rapidly in recent years due to population growth and increased per capita consumption. Most of the increase is in the developing countries. 70% of water use is for agriculture, 22% is for industry and 8% for domestic purposes, although there is considerable regional variation.
  2. Water is not scarce globally, but it often is on a continental or national scale. It is estimated that 31% of the global population will live in a waterscarce country (having less than 1000 m3 of fresh water per person per year) by 2025.
  3. Water is often unsafe to drink because of pollution. This varies with continent and locally between cities and rural environments.
  4. Water shortages have been the cause of major international disputes, particularly in the Middle East.
