Water requirement and food

Food production requires huge amount of water. One tonne of wheat needs 1,000 tonnes of water. If our daily drinking average is 4 liters per day, the water required to produce our food is 2000 liters or 500 times more. In affluent society, where grain is used in the form of livestock products, water consumed for our daily food production can reach 4,000 l/d.(FAO 2003).
