How much water do farmers use in California?

How will Arizona's water cutbacks affect farmers?
So far, mandatory cutbacks have mostly affected farmers in Arizona, who use nearly three-quarters of the state’s available water supply to irrigate their crops. The Colorado river helps fuel about 2.5 million acres of croplands across the western U.S.
Why don't urban gardeners use more water?
Because water is so inexpensive at the farm scale, there may be inefficiencies in irrigation and harvesting at the farm scale that do not translate to the small urban garden. Consequently, there are ways an urban gardener can reduce the amount of water applied and purchased.
Do farmers get water for free?
Irrigated agriculture remains the largest user of water globally, a trend encouraged by the fact that farmers in most countries do not pay for the full cost of the water they use.
Do farmers pay for groundwater?
The problem is that in most of California, agricultural groundwater use has long been a free-for-all. While the use of surface water (like river water) is limited, essentially anyone who owns a parcel of land can pump groundwater without limit and free of charge — farmers pay only the energy costs to extract it.

Why do farmers water during the day?
In plants, water passes through the stomata, which are small pores in the epidermis of leaves, stems and other organs. During the day, the stomates open to allow water to be taken from the plant's roots, then trade that water with carbon dioxide so that photosynthesis (and thus, plant growth) can occur.
Why is the cost of water a major concern for farmers?
Insufficient Water Water is a vital component of farming and natural ecosystems. Inefficiently managing the moisture in soil can lead to poor crop yields and increased runoff. In cropland, poor yields could be attributed to an insufficiency of soil moisture instead of inadequate rainfall.

Examples of such projects include DonPedro Reservoir, which is operated jointly by the Modesto and Turlock irrigation districtsand San Francisco’s Hetch Hetchy Reservoir and Aqueduct.
Why are crops important to farmers?
Crops such as rice and alfalfa provide valuable wildlife habitat andgrowing diverse crops can be invaluable to a farmer’s overall enterprise. Differentcrops use and return different nutrients to the soil and many crops are planted inrotation to provide to the soil balance and allow the land to regenerate. Somecrops, such as grains, are less water intensive per unit of production and therefore allowa farmer to keep more land in production when less water is allocated.
How much did agriculture contribute to the economy in 2004?

Why did California build dams?
Surface water supplies were developed early in the state’s history.Californians built dams, canals, pumping plants and aqueducts to carry waterto burgeoning cities and productive but dry farmland. These supplies were developedto compensate for the state’s uneven natural water distribution and to supplementavailable groundwater supplies.
How much water do vegetables need in California?
In practice, many vegetables need an application of water 2 to 3 feet deep to complete their life cycle, so on a volume basis this would add up to 2 to 3 acre-feet of water. So, how does the water cost translate ...
How much water does lettuce need?
So, how does the water cost translate to the yield and price of vegetables you may grow in your urban garden, like lettuce for your salad? Lettuce needs about 3 feet of water with conventional irrigation (sprinkler, flood or furrow). Consequently, the cost of 3 acre-feet of water for lettuce growing in a city is nearly $5,000. Of course, the cost of water will scale with the size of the urban garden plot and be less with smaller gardens. In comparison, the wholesale market value of an acre of lettuce produced by a farmer in the Salinas Valley is between $6,000 to $8,000. While the net margin difference in receipts and cost of water is still positive, it does not consider added costs of labor, value of land, seed and machinery to till ground.
What is supplemental irrigation in sub-Saharan Africa?
Agriculture in sub-Saharan Africa (SSA) countries is predominantly rainfed, but SSA could develop greater dependence on supplemental irrigation due to a changing climate with greater rainfall uncertainty and higher frequency of dry spells. Supplemental irrigation through small-scale water harvesting (SSWH) plays a vital role in helping rainfed small-scale farmers overcome the risk of dry spells and promotes greater investment in agriculture. This study employs a contingent valuation approach to estimate the demand for SSWH supplemental irrigation in Ghana. The study finds the mean willingness-to-pay estimates for SSWH supplemental irrigation to be GHC 25.36 (USD 6.67) per acre per season for open canal irrigation system and 24.76 (USD 6.52) per acre per season for pipeline irrigation system. Drought experience, access to credit, agricultural income, and land ownership are key determinants of the demand for SSWH supplemental irrigation. The findings are particularly important for pricing small-scale irrigation services from rainwater harvesting public water reservoirs. The study recommends that investing in rainwater harvesting in rainfed agriculture should form a cornerstone of any country's strategy for adapting to drought, particularly in developing countries where rainfed agriculture plays an important economic role.
How does tannery affect water?
The use of tannery effluent contaminates water for agricultural purpose had impacted rice growers in large scale. The present study has been conducted among rice growers in Walajapet block of Vellore district. A sample of 110 paddy farmers was selected using a proportionate random sampling method for the study. Ex-post facto research design has been used in this study. Results reveal that increased soil salinity, depleted soil nutrients, frequent pest and disease outbreak, increased cost of cultivation were the impacts faced by the paddy farmers.
How much does a farmer get for water?
Anywhere from $10-$15 per acre foot to $2,500, depending on location . Contrary to Mr. Jones’ post, only a small portion of the water farmers use receives a subsidy (interest forgiveness on the remaining portion of the capital cost), and that accounts for a small portion of their total water cost. The great majority of farmers do not receive any subsidized water. In recent years, the amount of subsidized water delivered to eligible districts was close to zero, and will likely remain very small in future.
Why are farmers selling their water rights?
CA is in a big drought and many farmers are just selling their water rights to other farmers because they don’t see any sense in trying to grow anything. Almond trees take tons and tons and tons of water and I imagine those might be the most affected. Cattle ranchers are selling off cattle early because they can’t afford to feed them. In general prices for food will go up in months to come from this. On the other extreme many farmers elsewhere have been flooded out and are not growing anywhere near what they usually do. This will also cause problems and price increases. Climate change is being

Why are there two reservoirs in California?
Only two new reservoirs have been built in California in the past 25 years, both to improve urban water supplies. For California agriculture to gain new water supplies, they must offer a joint environmental and agricultural benefit. One reason is that farmers alone likely cannot pay for the water it would yield and need the support of environmental groups to pay for the dams.
