Do Almonds Use More Water Than AI?

Yes, by a wide margin. California’s almond orchards use far more water than every data centre in the United States, AI and otherwise. The Lawrence Berkeley National Laboratory’s 2024 data centre report puts direct water use by US data centres, mostly for cooling, at 66 billion litres in 2023. Counting the water consumed at the power plants that supply their electricity adds nearly 800 billion litres more.

Almond estimates vary with acreage and method. The Pacific Institute estimated total applied water for California almonds at around 3.1 million acre-feet in 2010. The California Water Impact Network, an advocacy group, put it at 4.7 to 5.5 million acre-feet a year in 2024. California had about 1.5 million acres of almonds in 2025, 1.4 million of them bearing, according to Almond Board of California and Land IQ. An acre-foot is about 1.23 million litres.

Even the lower almond figure is more than 50 times the data centres’ direct use, and about four times direct and indirect use combined. Two caveats. The Berkeley figures cover all US data centres, not AI alone; no official body yet publishes a separate water figure for AI workloads. And data-centre use is rising: the same report expects hyperscale sites alone to consume 60 to 124 billion litres directly in 2028.

Water Usage in Almond, Walnut & Pistachio Farming: The 2026 Scenario

Nut cultivation remains among the most notorious high water usage sectors in global agriculture.
When comparing almond water usage compared to walnuts and pistachios, stark differences reflect the crop types’ physiology, irrigation needs, climate adaptability, and farming methods employed.
In 2025 and beyond, advances in precision agriculture, especially in California and Central Asia — two hotbeds for nut production — are reshaping how farmers manage water to address intensifying scarcity.

Why are Almonds Considered Water-Intensive?

• ✔ Almond trees require sustained irrigation to thrive — especially in the dry, Mediterranean-like climates of California, a region responsible for 80% of the world’s almond supply.
• ✔ Producing 1 kilogram of shelled almonds takes about 16,000 liters of water as a global average, counting rain, irrigation and pollution dilution (Water Footprint Network). In California, irrigation alone is roughly 4,300–4,700 liters per kg (Pacific Institute).
• 📊 Almonds have a deep-root system, demanding continual water access throughout the growing season.
• ⚠ This high level of consumption has made almonds a target for sustainable agriculture critics.

Walnut Water Usage: How Does It Compare?

• ✔ Walnuts use about 4,900 liters per kilogram in shell, 9,300 liters per kilogram shelled (WFN).
• 📊 Their growing season is typically longer than almonds but requires moderately less water per period.
• ⚠ Like almonds, walnuts are often cultivated in arid zones with increasing water scarcity, especially in Central Asia and California.

Pistachio Water Usage: Drought-Tolerant, Not Low-Water

• ✔ Pistachio trees tolerate drought, but their global average water footprint is about 11,400 liters per kilogram (WFN).
• 📊 That is more per kilogram than almonds or walnuts in shell (about 8,000 and 4,900 liters), so drought tolerance does not make pistachios the low-water nut.

Key Differences in Traditional Water Usage Patterns

1. Almonds: Deep roots, need sustained and heavy irrigation, especially in dry periods.
2. Walnuts: Moderate water needs, lengthy season, less frequent but more prolonged watering.
3. Pistachios: High adaptability to drought, less overall irrigation required per growing cycle.

Water Consumption: By The Numbers

• 🌱 Almonds: ~16,000 liters/kg shelled (global average, WFN)
• 🌱 Walnuts: ~9,300 liters/kg shelled (global average, WFN)
• 🌱 Pistachios: ~11,400 liters/kg (global average, WFN)

Water Footprint Comparison: Almond, Walnut, Pistachio

Note: Figures are global average total (green, blue and grey) water footprints from Mekonnen & Hoekstra (2011), Water Footprint Network. There are no per-kg figures for aeroponic almonds, walnuts or pistachios, because no commercial orchard grows them that way.

Aeroponics Water Usage Compared to Traditional Farming: A Breakthrough for the Future

Aeroponics works by suspending plant roots in air and misting them with nutrient-rich water. Soilless systems like this can use much less water than field irrigation for the crops where it has been measured: a peer-reviewed Arizona comparison modelled hydroponic lettuce at about 20 litres per kg against about 250 litres per kg in the field, roughly 13 times less (Barbosa et al., 2015). No commercial almond, walnut or pistachio orchard is grown aeroponically; tree crops have only been trialled at the seedling or nursery stage.

How Aeroponics Works: Key Features

• 🔵 Closed-loop Systems: Water and nutrients are recycled within a contained chamber, preventing waste.
• 🔵 Precision Delivery: Misting is regulated based on plant need and environmental sensors, dramatically reducing consumption.
• 🔵 Less Evaporation: No soil means almost no water lost to run-off or deep percolation.
• 🔵 Reduced Water Use: Because the nutrient solution is recirculated, aeroponic systems use much less water than open-field irrigation.
• 🔵 Year-Round Production: Controlled environment enables continuous production, smoothing out supply and demand patterns for nuts and other crops.

Aeroponics water usage compared to traditional farming is so efficient that it’s earning strong consideration for seedling production, high-value nut crops, and even urban vertical farms in water-stressed cities in 2026.

Aeroponics Limitations and Critical Contemplations

• ⚠ Initial Capital: Higher up-front investment for controlled environment and misting infrastructure.
• ⚠ Nutrients Management: Requires sophisticated nutrient and disease control techniques.
• ⚠ Tree Nut Viability: Full lifecycle commercial nut production (like almonds and walnuts) in aeroponics has not been demonstrated; trials are limited to seedlings and nursery stock.

Aeroponics Innovations for 2026 & Beyond

• ✔ Hybrid Systems: Combining aeroponics with smart soil sensors and AI-driven irrigation for large orchards.
• ✔ Urban Vertical Farms: Nut seedlings and select high-value crops can be grown with minimal land in cities facing severe water limits.
• ✔ AI Integration: Sensor arrays optimize mist output and nutrient flow to precisely meet plant requirements 24/7.

📋 Visual List: Aeroponics vs. Traditional Farming Key Takeaways

• 💧 Water Use: Soilless systems use much less water per kilogram than field growing for crops where it has been measured, such as lettuce.
• 💡 Precision: Real-time moisture and nutrient data minimize excess and loss.
• 🌍 Greater Sustainability: Efficient for future food production under increasing water scarcity conditions.
• 🛠 Flexibility: Deployable in deserts, cities, or spaces with poor/arid soils.
• 🔬 Experimental Edge: Active R&D from 2025 onward for tree nut crop viability.
