Mexico Water Crisis Could Cost Up to 5% of GDP, Experts Warn
MEXICO · ECONOMY
Key Facts
—The warning: Mexico’s water crisis could affect output equivalent to 4 to 5 percentage points of GDP, the head of the Water Advisory Council (CCA) told EFE.
—The gap: International organizations recommend investing 1.3 percent of GDP a year in water; Mexico is far below that level. One point of GDP is about 350 billion pesos (US$20.5 billion) annually, needed for at least a decade.
—The plan: President Claudia Sheinbaum’s government has earmarked 186 billion pesos (US$10.9 billion) for water investment through 2030.
—The exposure: Agriculture consumes about 76 percent of the water used in Mexico, and experts warn of production curbs, rising costs and supply-chain disruption.
—The current cost: Insufficient treatment and water discharges already generated losses above 66 billion pesos (US$3.87 billion) in 2023 — over 102 billion pesos (US$5.99 billion) including aquifer depletion.
The Mexico water crisis is no longer only an environmental story. Specialists now put a macroeconomic price tag on it: four to five points of GDP at risk unless investment rises sharply and stays high for years.
Mexico’s worsening water scarcity could affect between four and five percentage points of gross domestic product, while investment in the sector remains far below the country’s needs, experts consulted by EFE warned on 31 August. The Mexico water crisis has moved from a regional supply problem to a national economic risk, they said, as drought, aquifer depletion and aging infrastructure converge with the upcoming debate over the 2027 federal budget.
A 4 to 5 percent GDP risk
The headline estimate comes from Raúl Rodríguez, president of the Water Advisory Council (CCA), a business-backed think tank. “There is talk that the global crisis could cost 1 percent of world GDP, but quite a few countries are at an average negative impact of between 2 and 10 percent of GDP. Where would Mexico be? We are talking about between 4 and 5 points of GDP that could be affected by this crisis,” he told EFE.
Rodríguez acknowledged that the current cost of the Mexico water crisis is “very difficult to estimate,” but placed the country at a medium level among economies facing damage from the deterioration and scarcity of water resources. The range he cited would put Mexico’s exposure well above the global average — a reflection of how far scarcity has advanced in key farming and industrial regions.
Investment far below the need
International organizations recommend annual water-sector investment equivalent to 1.3 percent of GDP, Rodríguez said, and Mexico “is far from that level.” By his estimate, an effort of close to one point of GDP would mean roughly 350 billion pesos (US$20.5 billion) per year, sustained for at least a decade.
He contrasted that need with the 186 billion pesos (US$10.9 billion) in water investment contemplated through 2030 under the plans of Sheinbaum’s government (2024–2030) — a program that includes about 20 billion pesos (US$1.17 billion) for water projects within the Plan México industrial strategy. Even spread over the remaining years of the administration, the committed sums cover only a fraction of what the CCA considers necessary.
With discussion of the 2027 federal budget approaching, Rodríguez asked for more resources for the sector and wider room for private co-investment. “Hopefully we will see a change, greater investment in this area,” he said.
Growth at risk, from farms to factories
Jorge Arriaga, executive coordinator of the Water Network of the National Autonomous University of Mexico (UNAM) and of the Regional Center for Water Security under UNESCO auspices, agreed that the deterioration of the resource can become a brake on the economy. “Water can limit economic growth,” he warned, citing “direct restrictions on production, rising costs, interruptions in supply chains” and impacts on food security.
Few sectors are as exposed as agriculture, which consumes around 76 percent of the water used in Mexico. Both specialists said farming requires deeper technification — drip irrigation, measurement and more efficient crops — to reduce its vulnerability. The stakes are rising with each decade: per-capita water availability in Mexico has fallen from about 10,000 cubic meters in 1960 to roughly 4,000 in 2012 and is projected by IMCO, the Mexican Institute for Competitiveness, at under 3,000 cubic meters by 2030, below the threshold international standards define as water stress. Around 15 million people still lack reliable access to potable water, according to national estimates.
The bill is already due
Some costs are no longer hypothetical. Rodríguez estimated that in 2023 insufficient treatment and water discharges generated losses above 66 billion pesos (US$3.87 billion), a figure that rises beyond 102 billion pesos (US$5.99 billion) once the depletion of aquifers and the degradation of the resource are included. That annual loss, he noted, is roughly half of what a serious investment program would cost — money the economy is already paying without fixing the underlying problem.
What to watch
Three markers will show whether the Mexico water crisis is being treated as the economic threat the experts describe: the size of the water allocation in the 2027 budget proposal due in the coming months; the degree to which private co-investment is opened in treatment, reuse and irrigation; and whether irrigation technification programs reach the states where scarcity and production overlap most.

Frequently Asked Questions
How much could Mexico’s water crisis cost the economy?
Raúl Rodríguez, president of the Water Advisory Council (CCA), told EFE the crisis could affect between 4 and 5 percentage points of Mexico’s GDP, placing the country at a medium level among economies hit by water deterioration and scarcity.
How much should Mexico invest in water?
International organizations recommend 1.3 percent of GDP per year. The CCA estimates one point of GDP at roughly 350 billion pesos (US$20.5 billion) annually, sustained for at least a decade. Current federal plans contemplate 186 billion pesos (US$10.9 billion) through 2030.
Which sector is most exposed to water scarcity in Mexico?
Agriculture, which consumes about 76 percent of the water used in the country. Experts from UNAM and the CCA say farming needs deeper technification, and warn of production restrictions, higher costs, supply-chain interruptions and food-security impacts.
What does water scarcity already cost Mexico?
The CCA estimates that insufficient treatment and discharges caused losses above 66 billion pesos (US$3.87 billion) in 2023, rising to over 102 billion pesos (US$5.99 billion) when aquifer depletion and resource degradation are included.
