In most regions of the world, over 70 percent of freshwater is used for agriculture.
By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals.
What crops in California use the most water?
Alfalfa and pasture are also the second- and third-most-water-intensive crops in California, requiring irrigation to be applied at depths of between three-and-half feet and five-and-a-half feet, according to the Pacific Institute’s calculations. (Almonds and pistachios are the fourth-most-water-intensive crops.)
How much water does California use?
A 2011 study of a sampling of 735 California homes across ten water districts found that the weighted average annual total water use of these homes was 132,000 US gallons (0.41 acre⋅ft) per year or 362 US gallons (0.00111 acre⋅ft) per household per day.
How much do California farmers pay for water?
Water $70 to $2.4 million per acre foot. California farmers pay an average of $70 per acre-foot for water to irrigate crops.
Why does agriculture use the most water?
When agricultural water is used effectively and safely, production and crop yield are positively affected. A decrease in applied water can cause production and yield to decrease. Management strategies are the most important way to improve agricultural water use and maintain optimal production and yield.
How many gallons of water does agriculture use?
Estimating Farm Water Use Needs
|Automatic flushing||1,000 to 2,000 gallons per wash|
|Sprinkler*||4,000 gallons per acre per day|
|Drip*||1,000 gallons per acre per day|
