Water use throughout the time

Global freshwater consumption rose sixfold between 1900 and more than twice the rate of population growth. About one third of the world's population already lives in countries considered to be 'water stressed' - that is, where consumption exceeds 10% of total supply. If present trends continue, two out of every three people on Earth will live in that condition by Global freshwater consumption rose sixfold between 1900 and more than twice the rate of population growth.

Some facts: While freshwater supply is limited, demand keeps on escalating as population grows and consumption per capita increases. During the last 70 years, the global population has tripled, but water withdrawals have increased over six times. Since 1940, annual global water withdrawals have increased by an average of nearly 3 per cent per year, while population growth has averaged between 1.5 and 2 per cent.

Increasing in number of people leads to increasing of water use and decreasing of availability of water on a per capita basis. In 1989 there was some 9,000 m 3 of freshwater per person available for human use. By 2000, that figure had dropped to 7,800 m 3 and is expected to plummet to 5,100 m 3 per person by 2025, when the global population is projected to reach 8 billion.

Global consumption of water is doubling every 20 years, more than twice the rate of human population growth, while pollution and over-extraction in many regions of the world has reduced the ability of supplies to meet demand. According to the United Nations, more than one billion people on earth already lack access to fresh drink water. If current trends persists, by 2025 the demand for freshwater is expected to rise to 56 per cent more than the amount that is currently available Global consumption of water is doubling every 20 years, more than twice the rate of human population growth, while pollution and over-extraction in many regions of the world has reduced the ability of supplies to meet demand.
