AGRICULTURE:
Agriculture is easily the world’s heaviest consumer of water, most of which is used for irrigation. It takes around 2500 kcal per day to meet one adult’s energy requirements. One kilogram of bread contains around 3500 kcal, and it takes roughly 1000
liters of water to produce one kilogram of bread under optimum growing conditions. Based on this assumption, it takes around 260 m3 of water to feed one person for one year with a vegetarian diet. The more meat contained in a person’s diet, the
higher the associated water consumption. When meat accounts for 20% of a person’s diet, twice as much water is consumed for its production.1 This calculation
does not take into account the fact that conditions for food production are seldom ideal.
Much of the water used is wasted due to crop failures and losses in irrigation. If production losses are factored in as well, 550 m3 of water are required to feed one person a purely vegetarian diet for one year. WaterMicronWorld,Ltd
