Walnut Production — Walnut production refers to the total quantity of walnuts harvested and produced from walnut trees within a country or region during a specific year. It measures the agricultural output of walnuts, including commercially cultivated walnut orchards and other agricultural production systems. The indicator represents harvested walnut quantities and is generally measured in tonnes, reflecting the scale, productivity, and growth trends of the walnut industry across different regions.
Worldwide production increased from approximately 3.26 million tonnes in 2015 to 4.35 million tonnes in 2024, highlighting sustained long-term growth in the global walnut industry. This expansion was supported by increasing orchard areas, higher yields, improved farming practices, and rising consumer demand for walnuts in food processing, bakery products, confectionery, snacks, and health-oriented diets.
Throughout the decade, leading producers such as China, the United States, Iran, Turkey, India, Chile, Mexico, France, and several European and Central Asian countries made significant contributions to global output . Government support, agricultural research, and investments in sustainable farming practices also strengthened productivity across many walnut-producing countries.
Despite the overall positive growth trend, annual global production experienced moderate fluctuations due to adverse weather conditions, including droughts, excessive rainfall, frost, heatwaves, and changing climatic patterns that affected flowering, pollination, and harvest yields in key producing regions. In addition, challenges such as water scarcity, pest outbreaks, labour availability, and rising production costs influenced output in certain years. Nevertheless, continuous technological advancements and improved farm management practices enabled producers to maintain resilient production levels and support long-term industry growth.
Walnuts remain one of the world's most valuable tree nut crops, supplying domestic consumption, food manufacturing industries, and international trade. Increasing awareness of the nutritional benefits of walnuts, expanding export opportunities, and growing demand for plant-based, protein-rich foods continue to drive global market expansion. Overall, global walnut production between 2015 and 2024 reflects a steadily growing, technologically advanced, and increasingly sustainable agricultural sector that plays a vital role in supporting food industries, rural economies, and international agricultural trade.
