The world uses:

By 2025, water withdrawals are predicted to increase by:

in developing countries

in developed countries

By 2025

1800 million people will be living in countries or regions with absolute water scarcity

2/3 of the world population could be under stress conditions caused by water scarcity

Did you know that:the world's six billion people are using 54% of all accessible freshwater contained in rivers, lakes and underground aquifers

the volume of freshwater resources is around 35 million km3, or about 2.5% of the total volume which is 1.4 billion km3

about 24 million km3 or 70% of freshwater resources is in the form of ice and permanent snow cover in mountainous regions, the Antarctic and Arctic regions

Water pollution, environmental degradation and disasters

the UN suggests that we need 20-50 litres of safe freshwater a day for drinking, cooking and cleaning

more than one in six people worldwide - 894 million - don't have access to 20-50 litres of safe freshwater a day

2.5 billion people, including almost one billion children, live without basic sanitation.

the daily drinking water requirement per person is 2-4 litres, but it takes 2000 to 5000 litres of water to produce one person's daily food

every 20 seconds, a child dies as a result of poor sanitation. That's 1.5 million preventable deaths each year

globally, diarrhea is the leading cause of illness and death, and 88% of diarrhea deaths are due to a lack of access to sanitation facilities, together with inadequate availability of water for hygiene and unsafe drinking water.

20-50L

2000-5000L

Did you know that:

every day, 2 million tons of human waste are disposed of in water courses

since 1900 we've lost half of the world's wetlands

Water footprints

between 1991 and 2000, over 665,000 people died in 2,557 natural disasters of which 90 percent were water-related events.

in developing countries, 70% of industrial wastes are dumped into waters where they pollute the usable water supply

Did you know that we need:

13 litres of water of a tomato

25 litres of water for a potato

35 litres of water of a cup of tea

70 litres of water for an apple

75 litres of water for a glass of beer

120 litres of water for a glass of wine

170 litres of water of a glass of

orange juice

184 litres of water for a bag of

potato

200 litres of water for a glass

of milk

2400 litres of water for a
