The report's authors forecast that the need for water would double within 50 years, due to global population rise, more people choosing to eat a diet of meat and vegetables rather than primarily consuming cereals, and climate change. [4] Generally, about one litre of liquid water gets converted to water vapour to produce one calorie of food.
These include water and waste treatment, electric power, and telecommunications services.

When ground water is extracted for irrigation and other uses, most of the return flows seep back into the ground instead of joining the nearby surface stream.
The water scarcity issues around the world largely revolve around lack of access to fresh water; water is still extremely abundant in the world. Desalination is a method of turning unusable saltwater into potable water. In a sense, it is transporting water from areas of high availability into low availability. Aqueduct systems do the same.
