How is water used for agriculture?

Around 70 percent of freshwater withdrawals go into agriculture. The uses within the sector are very diverse and include mainly irrigation, pesticide and fertilizer application, and sustaining livestock. Further along the value chain, water is used for food preservation (crop cooling, for example) and processing.

How can farmers use water?

Through the process of drip irrigation farmers can supply water directly to the roots of their crops rather than sprinkling the water on top. Through properly installed drip irrigation systems, farmers can save up to 80% more water than standard sprinkler irrigation systems. Additionally, by creating ponds and reservoirs, farmers can draw their supply from there, taking the pressure off of local watersheds.

Why does farming livestock require a lot of water?

Farming livestock requires a considerable amount of water due to the amount of animals that need to be fed, cleaned, and maintained. The water intensive form of farming livestock is dairy farming.

How much water does a cow use?

The water intensive form of farming livestock is dairy farming. For just one milking cow, daily water usage is roughly 40-50 gallons when accounting for basic consumption and hygiene. However, when looking at livestock as a whole, it accounts for just 30% of the 2 quadrillion gallons used for agriculture annually.

Why do fruits and vegetables require the most water?

Farming fruits and vegetables requires the most amount of water to keep plants hydrated to produce enough food to feed the country. For example, to grow one pound of coffee 2,500 gallons of water will be used. Plants require consistent amounts of water everyday to take their life cycle from seed all the way to harvest. Another reason why farming produce requires such a large percentage of water when compared to farming livestock due to a large amount of the water being wasted through irrigation.

How can farmers draw their supply from there?

Additionally, by creating ponds and reservoirs, farmers can draw their supply from there, taking the pressure off of local watersheds. As the practice of farming changes, and the number of people on Earth grows, we must continue to look for more ways to conserve and maintain our global water supply.

Why do plants need water?

Plants require consistent amounts of water everyday to take their life cycle from seed all the way to harvest. Another reason why farming produce requires such a large percentage of water when compared to farming livestock due to a large amount of the water being wasted through irrigation.

How much water is lost to the environment?

On average, farms around the world account for 70% of all water that is consumed annually. Of that 70% used by farmers, 40% is lost to the environment due to poor irrigation systems, evaporation, and overall poor water management. As the world continues to increase in population, demand for food and water will continue to rise.

What is the largest share of the nation’s consumptive water use?

Irrigated agriculture , which accounts for the largest share of the Nation’s consumptive water use ( see definitions ), makes a significant contribution to the value of U.S. agricultural production. In 2012, irrigated farms accounted for roughly half of the total value of crop sales on 28 percent of U.S. harvested cropland.

What is water use estimate?

U.S. Geological Survey water use estimates generally refer to withdrawals, or the quantity of water withdrawn from a water source —e.g., a river, lake, or aquifer.

How does gravity irrigation work?

Gravity irrigation systems use on-field furrows or basins to advance water across the field surface through gravity-means only. Pressurized systems apply water under pressure through pipes or other tubing directly to crops. Pressurized irrigation includes acres irrigated by sprinkler and micro/drip irrigation systems. Under many field conditions, pressurized irrigation systems are generally more water-use efficient than gravity systems as less water is lost to evaporation, deep percolation and field runoff. Over the last 30 years the conversion of gravity to pressurized irrigation systems has increased. In 1984, 37 percent of all irrigated cropland acres in the western U.S. used pressurized irrigation systems, as compared with 72 percent in 2018.

What are the topics examined in the irrigated agriculture?

Topics examined include the following: The value of irrigated agriculture to U.S. agriculture; Where irrigation occurs across the United States; Crops produced with irrigation; Trends in water use and onfarm irrigation efficiency; Private and public investment in irrigation improvements; and. Definitions.

What is the importance of irrigation in agriculture?

Water applied as irrigation allows for crop production in arid regions and supplements soil moisture in humid regions when growing season precipitation is insufficient. Irrigation has enhanced both the productivity and profitability of the agricultural sector. According to the 2017 Census of Agriculture, farms with some form of irrigation accounted for more than 54 percent of the total value of U.S. crop sales, while irrigated land accounted for less than 20 percent of harvested cropland. Irrigated crop production helps to support local rural economies in many areas of the U.S., and contributes to the Nation’s livestock, food processing, transportation, and energy sectors.

How many acres of land were irrigated in 2012?
