Water use

Did you know that the world uses:
• 70 percent freshwater for irrigation
• 22 percent freshwater for industry
• 8 percent freshwater for domestic use
Did you know that by 2025, water withdrawals are predicted to increase by:
• 50 percent in developing countries
• 18 percent in developed countries
Did you know that by 2025:
• 1800 million people will be living in countries or regions with absolute water scarcity
• two-thirds 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 percent 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 percent of the total volume which is 1.4 billion km3
• about 24 million km3 or 70 percent of freshwater resources is in the form of ice and permanent snow cover in mountainous regions, the Antarctic and Arctic regions

Drinking water and sanitation
Did you know that:
• 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
• 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
• 2.5 billion people, including almost one billion children, live without basic sanitation.
• every 20 seconds, a child dies as a result of poor sanitation. That’s 1.5 million preventable deaths each year
• globally, diarrhoea is the leading cause of illness and death, and 88 per cent of diarrhoeal deaths are due to a lack of access to sanitation facilities, together with inadequate availability of water for hygiene and unsafe drinking water.

Water, agriculture and food security
Did you know that:
• it takes 1000-3000 litres of water to produce one kilo of rice
• it takes 13000 to 15000 litres of water to produce one kilo of grain-fed beef
• 277 million hectares, about 20 percent of all cropland is under irrigation
• rainfed agriculture is practiced on 80 percent of the arable land
• irrigation multiplies yields of most crops by 2 to 5 times
• irrigated agriculture currently contributes to 40 percent of the world’s food production and the remaining 60 percent comes from rainfed systems
• over the period to 2050 world’s water will have to support the agricultural systems that will feed and create livelihoods for an additional 2.7 billion people
• rapidly growing demand for meat and milk in urban areas of developing countries will place substantial new demands on agricultural water resources, especially for feed production.

Water pollution, environmental degradation and disasters
Did you know that:
• every day, 2 million tons of human waste are disposed of in water courses
• in developing countries, 70 percent of industrial wastes are dumped into waters where they pollute the usable water supply
• since 1900 we’ve lost half of the world’s wetlands
• between 1991 and 2000 over 665,000 people died in 2,557 natural disasters of which 90 percent were water-related events.
