10-Year Production Trajectory: Rising Stars & Fading Producers
Romania is the EU’s leading walnut producer, delivering between 20.9% and 30.0% of total EU output across the decade. Romanian production rose from 31.9 thousand tonnes in 2016 to 50.9 thousand tonnes in 2025, adding 18.9 thousand tonnes at a 5.31% CAGR. Romania’s trajectory featured steady mid-decade growth, peaking at 58.1 thousand tonnes in 2023 — its strongest single-year performance — before settling to 50.9 thousand tonnes in 2025. Romania recorded years below its decade mean in only 4 of 10 years, underscoring the consistent upward momentum.
Greece is the decade’s most dynamic — and volatile — producer. Greek output rose 75.3% from an estimated 28.1 thousand tonnes in 2016 to an estimated 49.2 thousand tonnes in 2025 at a 6.44% CAGR, adding a net 21.1 thousand tonnes. All Greek values carry an estimated (e) flag throughout the decade. The trajectory was anything but smooth: production spiked to 66.0 thousand tonnes in 2021, fell to 39.6 thousand tonnes in 2023, surged to an extraordinary 96.9 thousand tonnes in 2024, then dropped 49.2% to 49.2 thousand tonnes in 2025. The 2024 value of 96.9 thousand tonnes was the highest single-year output recorded by any country in the dataset, yet its precipitous decline the following year exemplifies the challenge of relying on Greek walnut supply.
France is the decade’s most consequential decliner. French output was the EU’s largest in 2016 at 40.5 thousand tonnes but fell to 34.3 thousand tonnes by 2025 (CAGR −1.81%), a net loss of 6.1 thousand tonnes (−15.1%). France’s best year came in 2022 at 49.7 thousand tonnes, driven by a strong harvest, but the general trend was downwards: production hit a decade low of 27.7 thousand tonnes in 2024. A break in series (b) flag in 2020 introduces some uncertainty into the long-run comparability of the data. Spain posted one of the steadiest growth profiles among the top 8, rising from 14.9 to 21.4 thousand tonnes at a 4.07% CAGR (+6.4 thousand tonnes net). Spanish output never fell below 14.9 thousand tonnes and expanded in 7 of 9 year-over-year intervals. Italy grew 25.6% from 12.2 to 15.3 thousand tonnes (CAGR 2.56%), with a notable spike to 21.9 thousand tonnes in 2022 — its best year — before settling back to the 15–16 thousand tonne range.
Portugal is the decade’s fastest-growing producer, expanding from 4.3 to 11.2 thousand tonnes at an 11.11% CAGR — more than doubling output (+158.1%). Portugal’s 2025 value of 11.2 thousand tonnes carries a provisional (p) flag. Poland followed a modest ascending trajectory from 7.2 to 8.1 thousand tonnes (CAGR 1.29%), though Polish output oscillated between a low of 3.7 thousand tonnes (2017) and a high of 10.7 thousand tonnes (2022). Hungary is the second and most pronounced decliner: output fell from 6.3 to 4.1 thousand tonnes (CAGR −4.72%), a 35.3% net loss, with a consistent downward trend accelerating after a 2017 peak of 7.9 thousand tonnes.

Supply Stability Scorecard: Reliability Rankings
Supply stability — measured by the coefficient of variation (CV%) — places Spain as the most reliable supplier among the top 8 producers, with a CV of 11.37% (moderately stable). Spain’s mean annual production of 17.47 thousand tonnes is modest relative to the top three, but its maximum single-year drawdown of only 12.13% makes it the most predictable source of walnuts in the EU. Spain recorded years below mean in 6 of 10 years, a consequence of its consistent upward trend elevating the decade average.
Romania, the bloc’s largest producer, ranks second in stability with a CV of 14.04%. This is a rare combination — being both the volume leader and among the most stable suppliers — and speaks to the maturity of Romanian walnut production. Romania’s maximum drawdown of 9.28% is the lowest of any country, indicating that even in the worst single-year drop, Romanian output contracted less than 10%. France ranks third on stability (CV 15.43%), but its supply risk profile is dominated by a maximum drawdown of 36.84% — the 2024 harvest of 27.7 thousand tonnes represented a 44.3% drop from the 2022 peak of 49.7 thousand tonnes. A break in series (b) flag in 2020 partially complicates long-run comparability.
Hungary’s stability profile is striking: a CV of 17.35% (moderately stable) conceals a maximum drawdown of 26.96% and a consistent downward trend. Italian walnut supply falls into volatile territory with a CV of 20.24% and a max drawdown of 31.60% — the 2022 spike to 21.9 thousand tonnes was followed by a 31.5% drop to 15.0 thousand tonnes in 2023. Poland (CV 26.07%), Portugal (CV 34.97%), and Greece (45.00%) occupy the most volatile positions. Greece’s CV of 45.00% is the highest in the dataset and reflects the extreme year-to-year oscillation — from 39.6 thousand tonnes in 2023 to 96.9 thousand tonnes in 2024 (+144.7%) and then back to 49.2 thousand tonnes in 2025 (−49.2%). Greece’s maximum drawdown of 49.26% is the largest single-year supply shock any EU buyer could have experienced during the decade.
CV < 10% = Very stable, 10–20% = Moderately stable, > 20% = Volatile. Greece’s extreme CV driven by the 2024 surge to 96.9 thousand tonnes followed by a 49.2% pullback in 2025.

Land Allocation Shift: 10-Year Cropland Transformation
EU-27 harvested area for walnuts expanded from 72.6 thousand hectares in 2016 to 109.4 thousand hectares in 2025 — a net gain of 36.8 thousand hectares (50.7%) at an annualized growth rate of 4.66%. Every top-8 country expanded its walnut area, making this one of the few crop categories with unanimous acreage growth among major producers. The EU total area CAGR of 4.66% runs ahead of the production CAGR of 3.20%, indicating that walnut cultivation is increasingly extensification-led — more land, not higher yields, is driving output growth.
France remains the EU’s largest walnut grower by area, expanding from 21.4 to 26.9 thousand hectares (+25.9%, annualized 2.60%). The divergence between France’s expanding area (+2.60% annualized) and declining production (−1.81% CAGR) signals a significant yield compression — French walnut yields have fallen from 1.89 t/ha in 2016 to an implied 1.27 t/ha in 2025, a decline of approximately one-third. A break in series (b) flag in 2020 warrants caution. Greece holds the second-largest walnut area at 19.5 thousand hectares in 2025, having expanded from 12.0 thousand hectares in 2016 (+62.0%, annualized 5.50%). All Greek area values carry estimated (e) flags.
Romania’s area expansion from 1.7 to 3.2 thousand hectares (+92.2%, annualized 7.53%) far outpaced its production CAGR of 5.31%. The dramatic disconnect between Romania’s high production volume and small harvested area — producing 50.9 thousand tonnes from just 3.2 thousand hectares — implies exceptionally high yields (15.9 t/ha in 2025), far above the EU average. Hungary recorded the most paradoxical land-use transformation: harvested area nearly doubled from 4.8 to 9.9 thousand hectares (+104.7%, annualized 8.29%), yet production fell 35.3%. Hungary’s implied yield per hectare collapsed from 1.31 t/ha in 2016 to 0.41 t/ha in 2025, a 68.7% decline. Portugal expanded area from 3.3 to 5.7 thousand hectares (+72.3%, annualized 6.23%), with the 2025 value flagged as provisional (p). Spain’s area grew modestly from 9.6 to 10.7 thousand hectares (+11.3%, annualized 1.20%), while production grew at 4.07% CAGR — the strong positive yield gap suggests efficiency gains outpacing land expansion. Italy added 2.0 thousand hectares (+44.1%, annualized 4.14%), and Poland expanded modestly from 2.5 to 2.9 thousand hectares (+17.4%, annualized 1.80%).

Frequently Asked Questions
Which EU country grew walnut production fastest over the decade?
Portugal grew fastest by CAGR at 11.11%, more than doubling output from 4.3 to 11.2 thousand tonnes (+158.1%). In absolute terms, Greece added the most — 21.1 thousand tonnes — though all Greek values carry estimated (e) flags. Romania remains the largest producer at 50.9 thousand tonnes in 2025, accounting for 25.1% of EU output.
Which country is the most stable walnut supplier in the EU?
Spain is the most reliable supplier with a coefficient of variation of 11.37% (moderately stable) and a maximum single-year drawdown of 12.13%. Romania combines top volume with second-best stability (CV 14.04%, max drawdown 9.28%) — a rare pairing that makes it the EU’s most strategically important walnut producer.
Where is EU walnut farmland expanding or shrinking?
All eight major producers expanded walnut area. The EU-27 total grew 50.7% from 72.6 to 109.4 thousand hectares. Hungary showed the largest percentage area expansion (+104.7% to 9.9 thousand hectares) despite a 35.3% production decline — a yield paradox likely reflecting orchard immaturity. No top-8 country registered contracting walnut acreage.
