As the need for water continues to increase to meet the demands of a growing population, understanding the relationship between groundwater and agriculture and groundwater and energy will be essential for safeguarding continued delivery of food, energy, and water to consumers.
The National Ground Water Association has researched and created an information brief that detail the importance of these relationships.
Agriculture requires a steady supply of water to meet crop and livestock requirements—linking food security directly to water security. Agriculture is the largest consumer of freshwater resources in the world.
Some countries do not have sufficient supplies of surface water to meet their agricultural demands, so groundwater is extracted to compensate for the difference.
In the United States, about 65% of groundwater withdrawals are for agricultural irrigation, which averages an estimated 50 billion gallons of water per day.
