How Arizona water gets “sold to Saudi Arabia”

Why this matters. The cargo is baled alfalfa, and the water rides along inside the crop. Once you see that substitution, the whole thing reads as ordinary commodity arbitrage against a mispriced input, and the policy options get much clearer.

This doc explains the mechanism, does the arithmetic, and covers why a state cannot simply ban the export.

1. Virtual water

“Virtual watervirtual waterThe water it took to grow or make something. Shipping alfalfa overseas exports the water inside it, even though no water crosses the border.” is the water consumed producing a good, accounted to wherever that good ends up. The term dates to the 1990s and is standard in water economics.

Alfalfa is a nearly pure virtual watervirtual waterThe water it took to grow or make something. Shipping alfalfa overseas exports the water inside it, even though no water crosses the border. product. It is bulky, cheap per ton, and has no value except as animal feed. Its entire economic content is the water and sunlight that grew it.

The United States exports about 82 trillion gallons of virtual water annually, more than twice any other country, and imports about 62 trillion gallons (National Geographic, citing UNESCO-IHE).

The numbers for Arizona alfalfa

Arizona uses more water per acre of alfalfa than any of the 7 western states in that study, because the low desert growing season runs nearly year round and supports up to 8 or 9 cuttings.

Work the arithmetic at 6 acre-feetacre-footEnough water to cover 1 acre a foot deep: 325,851 gallons. Roughly what 2 or 3 suburban households use in a year. per acre and 8.3 tons per acre. A single ton of Arizona hay embeds about 235,000 gallons. A truckload of 25 tons embeds about 5.9 million gallons. A 3,000 acre farm consumes about 18,000 acre-feetacre-footEnough water to cover 1 acre a foot deep: 325,851 gallons. Roughly what 2 or 3 suburban households use in a year. per year, roughly 5.9 billion gallons, which is water for something like 54,000 Arizona homes at the Attorney General’s conversion of 3 homes per acre-foot.

That is the number that makes people angry, and it is correct.

Why alfalfa specifically

Alfalfa fits the arbitrage better than any other crop.

It is a perennial, so you plant once and cut repeatedly, which converts a water input directly into tonnage with minimal labor. It tolerates heat and salinity. It has a deep, established global trade in dry baled form with container logistics already built out.

Shipping economics help. Empty containers head back to Asia and the Gulf anyway, so backhaul rates are cheap. One water economist noted it costs less to ship a ton of alfalfa from Long Beach to Beijing than from California’s Imperial Valley to the Central Valley (National Geographic, 2014).

And alfalfa is fungible. A ton of hay is a ton of hay, so the only lever on margin is input cost. When water is free, the producer with free water wins.

The Saudi ban, in detail

The Saudi Ministry of Environment, Water and Agriculture issued a 3 year phase-out plan in December 2015, reaffirmed it in October 2016, and detailed the restrictions in October 2017. The ban took effect in early November 2018 across the 6 major fodder-producing regions: Riyadh, Eastern Province, Qassim, Hail, Jouf and Tabuk (MEWA, Netherlands agricultural service summary).

Ministry estimates: green fodder consumed more than 17 billion cubic meters of water per year, and the ban would save roughly 8 to 9 billion (Argaam).

The replacement plan named 7 approved investment paths for displaced growers. Path 7 was “cultivation of green fodder outside the Kingdom for export to Saudi Arabia.” The offshoring was policy, stated in writing.

USDA forecast the shift would add roughly 825,000 metric tons of annual import demand worth about $250 million at 2016 prices (USDA FAS GAIN report, 2017).

Note that Fondomonte’s Arizona purchase closed in March 2014, before the first decreedecreeThe court order at the end of an adjudication, spelling out exactly who gets how much water and in what order.. The company was ahead of the policy, which is what you would expect from an operator that saw the ban coming.

3. The state land lease angle

The purely private half of this (land Fondomonte owns in fee) is a normal property transaction. The part that generated a scandal is the land Arizona leased to it.

Fondomonte held 5 state trust land leases in La Paz County totaling more than 6,608 acres: 4 in the Butler Valley Basin (3,520 acres) and 1 in the Ranegras Plain Basin (3,088 acres, running to 2031), plus 3,163 acres of state grazing land (Arizona Auditor General Report 24-101, Feb 2024, KJZZ).

State trust land in Arizona is held for beneficiaries, mostly public schools. The State Land Department has a fiduciary duty to get market value.

The Auditor General found it had not. As of calendar 2023, the Department was still charging agricultural lessees in farm areas 3 and 6, including Fondomonte, rates set in 2006 from a 2005 mass appraisal. Against that stale 2005 appraisal, rates ran about 46 to 48 percent below market. Against a 2018 market study the Department commissioned and then never applied, rates ran about 80 to 83 percent below market (Auditor General Report 24-101).

The leases charged for the surface only. Groundwater came with the lease at zero price and zero quantity limit, and the Department did not require the lessee to disclose how much it pumped.

Read as a term sheet, Arizona sold surface access at roughly 20 cents on the dollar and threw in an unmetered call option on the aquiferaquiferUnderground rock or sand with water in the spaces between the grains. It is not an underground lake. Water seeps through it slowly, often only feet per year.. The Governor’s office later described the pumping as occurring “free of charge” and cited it as the reason not to renew (Governor’s office, Oct 2, 2023).

Butler Valley made it worse. Almost all land there is state or federally owned, and the state parcels were specifically set aside as a groundwater reserve for the initial AMAsActive Management AreaAn Arizona zone where groundwater pumping is actually regulated: metered, reported, and capped. Outside these zones there historically were no limits at all., meaning Phoenix, Pinal, Prescott, Tucson and Santa Cruz. Arizona was leasing out the surface of its own strategic water reserve (ASU AZ Water Innovation Initiative).

4. Who else does this, and how much of the problem is foreign

This is where most coverage went wrong, so be careful with the numbers.

Other foreign operators

Al Dahra, an Emirati agribusiness, farms about 3,000 acres of forage near Wenden in the McMullen Valley. Its water use is not tracked by the state; a neighboring farmer estimated 15,000 to 16,000 acre-feet per year from his own operation’s requirements. Al Dahra leases from a private North Carolina corporation, which gives Arizona less control than it had over Fondomonte’s state leases. The company is controlled by ADQ, an Abu Dhabi state investment holding company (AP, Nov 2023).

Fondomonte also farms in California’s Palo Verde Valley near Blythe, buying 1,790 acres for nearly $32 million in January 2016. Those operations draw Colorado River surface water under an existing entitlement rather than unregulated groundwater, and they have attracted far less scrutiny (CNBC, Jan 2016).

The volume math

Put the foreign share in context against the whole state.

Sources: Arizona Senate issue brief, ADWR agriculture page, UA MAP Dashboard, WAEA 2023, AG complaint, Dec 11, 2024.

Be fair about what this shows. The overwhelming majority of Arizona groundwater depletion is caused by American farms and American cities. Foreign-owned farms are well under 1 percent of Arizona farms. Domestic alfalfa growers in the same basins pump comparable volumes per acre and face the identical (nonexistent) rules. The Arizona Farm Bureau has pushed back on the “groundwater pirates” framing, and on the volume math it has a point.

Two things are true at once. The foreign angle got the coverage that finally moved policy, and the foreign angle is a small minority of the volume. Anyone selling you the story as a national security problem is overstating the hydrology. Anyone dismissing it because the volume is small is missing that a basin is depleted locally, and in the Ranegras Plain, Fondomonte was the single largest user in a basin whose withdrawals exceeded inflows by more than 900 percent.

Basin-level concentration is what matters for the neighbor whose well went dry. Statewide percentages are what matter for the aquiferaquiferUnderground rock or sand with water in the spaces between the grains. It is not an underground lake. Water seeps through it slowly, often only feet per year. as a whole. Keep the 2 questions apart.

5. Compare: exporting water in a pipe

Arizona has a second, entirely separate practice that actually does move water: “water ranchingwater ranchingThe same practice as buy and dry, usually run by an investor rather than a city utility.,” or buy-and-drybuy and dryBuying farmland mainly for its water, retiring the farming, and moving the water to a city. It works financially and it hollows out the communities it drains..

The pattern is simple. An investor or a city buys farmland whose value is mostly its attached water entitlement, retires the farming, and transfers the water to a municipal user.

The canonical deal: Greenstone Resource Partners, through subsidiary GSC Farm LLC, bought 485 acres in Cibola, La Paz County, in 2013 and 2014 for about $9.8 million. In 2018 it agreed to sell the attached Colorado River entitlement to Queen Creek, a fast-growing Phoenix suburb 200 miles away, for about $21 million. ADWR endorsed the transfer in September 2020, recommending approval of a partial volume. Reclamation ultimately approved 2,033 acre-feet per year in April 2023. Greenstone’s gross profit was around $14 million (Guardian, Apr 2024, azcentral, Nov 2021).

A federal court later ordered a full environmental impact statement, and Reclamation issued a notice of intent to prepare one in September 2025 (Federal Register).

Pipe versus bale

The regulatory asymmetry is the whole point. Moving 2,033 acre-feet through a canal took roughly a decade, 2 agencies, a lawsuit and an environmental impact statement. Moving 31,196 acre-feet through hay bales in a single year took no approvals at all.

Water law regulates the transfer of a water right. Virtual water export never touches a water right. The water is consumed on site, in place, by a crop, entirely legally, and what crosses the border is a dry agricultural commodity.

6. The federalism constraint: why a ban probably fails

The obvious response is to ban exporting Arizona water out of state. The Supreme Court closed that door in 1982.

In Sporhase v. Nebraska ex rel. Douglas, 458 U.S. 941 (1982), decided July 2, 1982, the Court held that groundwater is an article of commerce, and therefore subject to the Commerce Clause and its dormant limits.

Nebraska’s statute required a permit to move groundwater to an adjoining state, conditioned on 4 findings. The Court split them:

The Court also held Congress had not consented to otherwise-impermissible state groundwater regulation, despite 37 federal statutes and numerous compactscompactA binding agreement between states that Congress approves. Once approved it becomes federal law and overrides conflicting state rules. The Great Lakes Compact is one. deferring to state water law (LII, Justia).

Full brief: ../01-cases/1982-sporhase-v-nebraska.md.

What a state can still do

Sporhase forbids discrimination against out-of-state or foreign users. It leaves a wide field of evenhanded regulation intact.

1. Regulate the pumping, not the destination. Cap withdrawals, require permits, require metering. A rule that applies to everyone in the basin survives Sporhase because the first 3 Nebraska conditions survived. This is exactly what an AMAActive Management AreaAn Arizona zone where groundwater pumping is actually regulated: metered, reported, and capped. Outside these zones there historically were no limits at all. designation does.

2. Charge for the water. A volumetric groundwater withdrawal fee applied uniformly is a classic evenhanded regulation. Arizona already levies withdrawal fees inside AMAs. Pricing an input at zero and then complaining who consumes it is a design failure, not a legal one.

3. Restrict transport between basins. A.R.S. § 45-544 and Article 8.1 already do this, and they are geographically neutral. They constrain moving water from basin A to basin B regardless of who owns the pump or where the owner is incorporated.

4. Manage state land as a landlord. The state has no obligation to lease its own trust land to anyone. Arizona has broad discretion over lease terms, renewal, rent, and water conditions as a proprietor rather than a regulator. This is the lever Hobbs actually pulled in 2023.

5. Enforce nuisance law. Public nuisance is a generally applicable state tort. Arizona’s AG sued under A.R.S. § 13-2917, a statute that says nothing about foreign ownership.

6. Restrict foreign ownership of land, carefully. Several states have passed farmland ownership restrictions aimed at specific countries. These raise separate constitutional questions (federal preemption of foreign affairs, equal protection, and in some cases the dormant Commerce Clausedormant Commerce ClauseA constitutional rule that stops states from unfairly blocking trade across state lines. It is why a state generally cannot just ban water from leaving.) and are being litigated. Treat as unsettled.

Notice what all the durable tools have in common. They regulate the resource or the conduct, never the nationality of the buyer. Every action that actually stuck against Fondomonte took that form.

---

7. Compressed answer to the original question

Arizona priced groundwater at zero across roughly 80 percent of its land area, and a Saudi dairy company bought the land sitting on top of it. No water is sold or shipped as water at any point in the chain.

The water leaves as alfalfa, at roughly 235,000 gallons per ton. The crop is a delivery vehicle.

Saudi Arabia banned this activity at home in 2018 to protect its own aquifers, and its own policy documents listed offshore fodder cultivation as an approved alternative.

The arbitrage was between 2 regulatory regimes, not between 2 countries. American farms in the same basins ran the identical trade, at greater aggregate volume, and drew almost none of the attention.
