Water scarcity factsheet

Agriculture
water scarcity info
Agriculture is by far the biggest user of water, accounting for almost 70 percent of all withdrawals, and up to 95 % in developing countries.

water scarcity infoThe water needed for crops amounts to 1000-3000 cubic meter per tonne of cereal harvested. Put another way, it takes 1—3 tonnes of water to grown 1kg of cereal.

water scarcity infoThe daily drinking-water requirements per person are 2-4 litres. However, it takes 2000—5000 litres of water to produce a person's daily food. —FAO

Food Security
water scarcity infoBetween now and 2030, the world's population is expected to grow by 2 billion people. Feeding this growing population and reducing hunger will only be possible if agricultural yields can be increased significantly and sustainably.

water scarcity infoWith so much of the Earth's water being used for agriculture, it is clear that an improvement in the management of agricultural water becomes key to the achievement of global food security.

Water
water scarcity info
One out of every three people is affected by water scarcity. Water researchers believe that the problem is getting worse with urbanization, population growth, industrialization and competitive commercial activities.

water scarcity infoAlmost one fifth of the world's population (about 1.2 billion people) live in areas where the water is physically scarce. One quarter of the global population also live in developing countries that face water shortages due to a lack of infrastructure to fetch water from rivers and aquifers. —WHO/Water Scarcity/Fact3

water scarcity infoIn many poor and rural communities, people use waste-water to water their crops and farms because there is water shortage or scarcity. It is believed that 10% of all the foods we eat come from crops cultivated by wastewater. These can contain chemicals or disease-causing organisms.
