Why is Water Consumption Increasing?

Like the increasing demand for food, water consumption is rising because of a growing global population and because of economic development.

Increasing global population size

Increasing global population size

  • The global population was 2.6 billion people in 1950.
  • The global population was 6.1 billion people in 2000.
  • The global population was 7.8 billion people in 2020.
    • The world contains 5.2 billion more people than 70 years ago.
  • The global population is expected to be 9.8 billion by 2050.
  • Water is drunk by humans, drunk by livestock, used for washing and manufacturing.
  • The growing demand for food also means that more water is needed to grow crops and rear livestock.
Economic development

Economic development

  • As countries become more developed, people's incomes rise and their preferences change.
  • People demand more food and more meat, which increases water consumption.
  • People demand more clothing and manufactured products, which also increase water consumption.
  • As countries develop, people wash more frequently, using more water for baths, showers, dishwashers, and washing machines.
  • 10% of the USA's water consumption is used in the energy generation process. Water is often used to cool power generators and power stations.
