How does agriculture use water?

There are four main areas of water use in agriculture: growing of crops, supplying drinking water to livestock, cleaning farm buildings and animals, and supplying drinking water for those who work on the farm. The amount of each category varies according to the type of farm. For example, farms in the eastern part of North America usually receive enough rainfall and water from melting snow to meet most of the water needs. But drier areas, such as the U.S. and Canadian prairies, regions of Mexico, and some mountainous regions of the West do not receive sufficient natural moisture. On these farms, water must be supplied through irrigation.

How much freshwater is used for irrigation?

Nearly 60% of the world’s freshwater that is used by humans is used for irrigation. Of this water that is applied to crop fields, only about half returns to surface water or groundwater sources. The rest is lost by natural processes such as evaporation (when liquid water changes to water vapor) and transpiration (when water from plant leaves is transformed into water vapor), and accidental occurrences such as leakage from pipes or spillage.

How does drip irrigation work?

In drip irrigation, water runs through pipes that have tiny holes in them. When buried underground, water can ooze out of the pipe into the soil near the roots of the plants. The loss of water is reduced and less water is required to grow the crops.

Which is the largest consumer of water?

In modern times, in countries such as the United States and Canada, agriculture is not the largest user of water but is the largest consumer of water. Other activities such as the oil industry use more water than does agriculture . But, in these other industries, much of the water is put back into the ground or surface water after being used. Agriculture consumes water; the water does not go back to the surface or to the groundwater.

What are the crops grown in San Joaquin Valley?

Crops grown in the San Joaquin Valley include grapes for the state’s famous wine industry, lettuce, peppers, cherries, almonds, peaches, tomatoes, and asparagus. These and other crops and livestock make for a $4 billion a year industry. Many valuable farmlands are also valuable to developers, who build new neighborhoods as the population in the San Francisco Bay area and other urban centers grow. California officials predict that by 2020, the population in the San Joaquin Valley will increase by over 50%, adding additional strain to the remaining farmland and water supply. While many California citizens welcome the new growth, local governments are working to meet the needs of growth while preserving farmlands.

Annual M&I deliveries for the state total about 975,000 AF, accounting for approximately 6.7% of total deliveries for the state (CWCB, 2011; State of Colorado, 2015)). Statewide, nearly 94% of the 975,000 AF is diverted from surface waters and only 6% withdrawn from groundwater aquifers (WEC, 2016); however, 19 of Colorado’s 63 counties rely solely on groundwater for potable and domestic uses (Colorado Geological Survey [CGS], n.d.). Groundwater withdrawals by public water supply systems and private wells serve an estimated 20% of the state’s population (CGS, n.d.).

Why do recreational and environmental water needs overlap?

Recreational and environmental water needs often overlap: increasing the flow of a stream not only benefits fish and other aquatic life, but is also beneficial to anglers. Conversely, sometimes conflict can arise between the two if, for example, ideal river flows for rafting drastically differ from prime flows to support fish habitat. The deep interconnectivity of recreational and environmental water uses mean they are usually assessed and often managed together.

Where does Colorado’s water flow?

To further complicate growing water supply needs, supplies are not necessarily where demands are: approximately 80% of Colorado’s water falls and flows west of the Continental Divide, while 80% of the population and the majority of irrigated acres are found east of the Divide (Water Education Colorado [WEco], 2014; Colorado Water Conservation Board [CWCB], n.d., 2011). Although the West Slope is projected to grow at a faster rate than the Front Range, the Front Range basins (Arkansas and South Platte) will continue to have the largest populations in the state (CWCB, 2011).
