Walnuts—renowned for their buttery flavor, health benefits, and culinary versatility—are cultivated across diverse climates worldwide. But one country stands head and shoulders above all others in production. Let’s crack open the data and discover which nation leads the world in walnut production, why it dominates, and what this means for the global market.
China: The Walnut King
Leading by a wide margin, China dominates the global walnut scene.
- Production volume: Approximately 1.4–1.5 million metric tons of in-shell walnuts per year fas.usda.gov+1currentaffairs.adda247.com+1, which translates to roughly 56–57 % of global output fas.usda.gov.
- Historical dominance: As of 2016/17, China already produced over 1.06 million tons, accounting for ~50 % of world output worldatlas.com. Recent growth continues; in 2023, production was about 1.1 million tons, and forecasts for 2024/25 estimate 1.5 million tons—a testament to rapid expansion fas.usda.gov.
- Production increase: A recent report highlights China’s overall output rising approximately +4 % year-over-year .
Why China Leads
- Ideal geography & climate
Regions such as Shaanxi, Hebei, and Xinjiang provide long, warm summers and well‑drained soils ideal for English walnut (Juglans regia) trees theworldranking.com+10worldpopulationreview.com+10en.wikipedia.org+10. - Investment & modernization
Robust infrastructure, government subsidies, and investment in precision agriculture, irrigation systems, and mechanization have significantly boosted yield efficiency sweetishhill.com+3currentaffairs.adda247.com+3en.wikipedia.org+3. - Domestic demand
Exploding per capita consumption—rising from 0.17 kg (1995) to 1.8 kg (2016)—fuels domestic market expansion alongside export potential worldatlas.com. - Export dynamics
While China consumes most of its walnut output domestically, it’s also increasing exports to markets like the UAE and Kyrgyzstan worldpopulationreview.com+3currentaffairs.adda247.com+3worldunfolds.com+3.
Thanks to this strategic synergy, China stands firmly as the world’s largest walnut producer.
United States: A Strong Second in California
The United States ranks second in global walnut production—anchored by California, which contributes nearly 100 % of U.S. output.
- Annual output: Around 607,000–689,000 metric tons, making up ~13–23 % of global production reportlinker.com+3worldpopulationreview.com+3bootstrapbee.com+3.
- Marketing year 2024/25 estimate: 607,814 tons (~23 % global) worldatlas.com+2fas.usda.gov+2fas.usda.gov+2.
California: The Walnut Powerhouse
- Native & cultivated: Home to the English walnut (Juglans regia) variety, introduced in the 1770s by Franciscan Fathers fas.usda.gov+5en.wikipedia.org+5en.wikipedia.org+5.
- Major acreage: By 2018, California had over 335,000 acres of walnut orchards, producing $1.6 billion worth en.wikipedia.org+1en.wikipedia.org+1.
- Yield per acre: Increased from 1.50 tons/acre (2007) to 1.87 tons/acre (2017) en.wikipedia.org.
- Export emphasis: California walnuts are heavily exported to the EU, Japan, South Korea, and others; in 2017 alone, exports totaled $1.37 billion .
However, challenges—like frosts, heat waves, and irrigation needs—have impacted recent yields. The U.S. walnut crop fell ~19 % in 2024/25 due to adverse weather, although stocks and exports rebounded slightly .
Other Key Walnut Producers
Although China and the U.S. dominate (~70 % combined output), other countries make important contributions:
| Rank | Country | Production (~2023‑24) |
|---|---|---|
| 3 | Iran | ~387,000 t (~6–7%) sweetishhill.com |
| 4 | Turkey | ~325,000 t (~2%) |
| 5 | Chile | ~195,000 t (7–3%) |
| 6 | Ukraine | ~115,000 t (~2.7%) |
| 7 | Mexico | ~136,000 t (3.8%) |
| 8 | Romania | ~54,000 t |
| 9 | France, Greece, Uzbekistan, etc. | 25,000–62,000 t range |
These countries benefit from favorable climates, heritage varieties, and, in some cases, government support. Iran—renowned for Persian walnuts from Kerman and Zanjan—ranks high due to efficient cultivation worldpopulationreview.com.
Global Walnut Production: Scope & Growth Trends
- Total global output has climbed to around 2.7 million metric tons (marketing year 2024/25) bootstrapbee.com+7fas.usda.gov+7fas.usda.gov+7.
- Ten-year growth: An average of ~3 % CAGR since 2015 (~2.29 million in 2015 to 2.69 million in 2024) fas.usda.gov.
- Leading share: In 2023, China contributed 57.7 %, the U.S. 13.0 %, Iran 6.7 %, with Mexico, Chile, and Ukraine each around 3 % reportlinker.com.

Why Production Varies: Key Factors
Walnut yields depend on a complex web of factors:
- Climate & soil
Trees thrive in long summers, well-drained soils, and cold winters for dormancy. Regions lacking these may see lower yields atlasbig.com+15worldatlas.com+15worldpopulationreview.com+15. - Water & irrigation
In arid zones, like California or Iran, sufficient irrigation is crucial. Droughts or water restrictions can severely limit output . - Orchard management
Techniques such as pruning, disease control, and beekeeping for pollination are essential for high yield . - Economic policy & subsidies
Many governments (China, Iran, Turkey) support walnut farmers through aid and research, pushing productivity worldatlas.com+11worldpopulationreview.com+11bootstrapbee.com+11. - Technological adoption
Precision agriculture, new cultivars, mechanized harvesting, and pest management enhance output and quality—especially in China and California . - Climate change
Rising temperatures, erratic rainfall, and extreme events are beginning to reduce yields in vulnerable regions .
What This Means for the Walnut Market
The global walnut industry is evolving rapidly:
