Walnut Production, Consumption and Trade in the Word and Turkey

According to FAO data in 2013, the word walnut production is about 3.5 million tons. Turkey made 190 thousand tons of it by taking a share of about 6% of world production which ranks fourth after China, Iran and the United States.
Production areas, production and yield From Table 1, 999.081 ha of walnut are produced in the world. 43% of this production area in China, 11% in the US, Turkey also has 10%.
Chart 3 shows that the average world walnut yield is 3.528 kg / ha. When countries are examined in terms of walnut yield, an interesting picture is encountered. In terms of walnut production and production areas, it is observed that the countries that are in the first place do not perform the same efficiency in productivity.  Slovenia ranks first in the world with a walnut yield of 22,294 kg / ha. It would be correct to say that Slovenia's success in the past is to cultivate high-yielding varieties suitable for the production of walnuts and to have a high rate of walnut hatching. China that is at the forefront in production and area statistics, ranks 14th with 4.000 kg / ha in productivity. Turkey is 1,950 kg / ha ranks 31 in the world with efficiency.
World walnut foreign trade is shown in Table 4.
Walnut is subject to foreign trade both crusted and without crust, and walnut foreign trade is increasing compared to years. The export amount (crusted + crustless) was 411,821 tons in 2009, 493,791 tons in 2013 and 20% increase in these years. Looking at Table 3, walnut imports in the world between the years 2009 and 2013 increased by 30%.
Table 4 and 5 shows that exports of 298.061 tons of inshell and 196.730 tons of kernel walnuts are exported to the world in 2013. The USA ranks first in world walnut exports. US takes share of 46% with 120,215 tons of inshell and 35% with 70,788 tons of kernel production in foreign trade.
Table 6 shows the share of countries in world walnut imports. In 2012, imports of 253.306 tons of inshell and 156.953 tons of kernel were imported in the world. As seen in Table 6, Chine which is the clear leader in the world of walnut production, is also has the first rank in the import of inshell walnuts.  Chine inshell walnut imports account for 20% of the total imports in the world.
Of the walnut producer countries, only US is the production export base. The US has been built on the policy of exporting walnut products and they are directing production for this purpose.
Although China has a 50% share in production, it is an absolute importer country, meaning that this large production is making up for domestic consumption. Iran, which is in the second place in the production order, gives the impression that the foreign trade does not take place in significant quantities and has a production amount to meet the domestic demand.
In Table 7, years in Turkey's walnuts foreign trade was examined. 2005-2014 period, Turkey's exports of walnuts (shelled + unshelled) has increased from 216 tons to 4884 tons. In the same period, the import amount increased from 14,360 tons to 27,457 tons. In the same period the product deficiency of Turkey has increased from 14 144 to 22 572 tons.

The scientific studies shows that; the production area will increase by 30% and consumption by 17% until the end of  2019, imports will increase to 40,785 tons and exports will increase to 5,603 tons by 2019, proportionally imports will increase further compared to exports and foreign trade will continue to increase if measures are not taken to increase production.
