Ukraine is a major player on the international agricultural market, accounting for about 10 percent of the global grain supply in recent years. In 2021, Ukraine exported 43.4 million metric tons of agricultural crops, most of which consisted of corn, wheat, and barley. About 90 percent of the exports were transported by sea. According to Ukrainian Grain Association President Nikolay Gorbachov, if it hadn't been for the war, Ukrainian grain exports may have reached 70 million metric tons this year — while the entire volume of global grain exports, according to the UN, was expected to reach 462.2 million metric tons.
Before the war, many Asian and African countries depended heavily on grain exports from Russia and Ukraine; at least 30 percent of their grain imports came from the two countries, and sometimes as much as 50 percent. The most dependent were Eritrea, Armenia, Mongolia, Azerbaijan, Georgia, Somalia, Belarus, and Turkey; these countries are now having to restructure their supply chains and search for grain on the global market, where the war has caused prices to surge from the already-high levels they reached during the pandemic.
The war may ultimately cause total global grain exports to fall by 5-10 percent, but not every crop will be affected equally. Ukraine provides about 10 percent of the world’s wheat exports, making it the sixth largest wheat exporter. Its share of global barley and corn exports is even higher, making it the third in the world. And Ukraine effectively monopolizes global sunflower seed exports, providing more than half of the traded volume, while Ukraine and Russia together account for more than 70 percent of the market.
Compared to the first months of this year, Ukraine’s grain exports have fallen by about two-thirds. Wheat exports specifically have almost stopped completely.
Russia, who launched a war of aggression against Ukraine. If that hadn’t happened, the grain from last year’s harvest that was intended for export would have left Ukraine already. What's important now is to figure out exactly how the current crisis developed and how it can be overcome.

In May, Turkey offered to implement a plan developed by the UN to get Ukrainian grain out of Ukraine. The details are still unknown; according to UN officials, disclosing them could disrupt “delicate negotiations.” All we know is that:
Even if Turkey manages to solve the problem of mutual distrust between Russia and Ukraine, the problem of insurance will remain: insurers won’t believe that export operations in Ukraine’s territorial waters can be safe while the war is still going on.
Definitely not all of it. If the grain were transported by railroad to the EU, it would have to be reloaded into different train cars due to the difference in standard track width in Ukraine and Western countries. Another problem is the lack of grain elevators in Poland, which would hinder the transshipment and further transportation of the millions of tons of grain. The U.S. has offered to build temporary elevators, but this is unlikely to solve the fundamental problem; according to Bloomberg, in the best possible scenario, Ukraine would manage to export two million tons out of the over 20 million tons of grain currently stuck there.
The biggest problem is the grain from last year’s harvest is currently sitting in elevators that will eventually need to be empty for the next harvest. In addition, a portion of the country’s elevators and flour mills have been destroyed or lost due to the war. As a result, there will be nowhere to put tens of millions of tons of grain that’s set to be harvested in the coming weeks, and the world could lose as much as 10 percent of its grain.
Theoretically, yes: according to forecasts from industry experts, Russia’s grain exports are set to grow this year. The country is expecting a record-setting harvest, and quotas restricting grain exports will expire on June 30. However, Western countries are concerned that Russia, on the contrary, will intentionally export less than usual; Security Council Deputy Chairman Dmitry Medvedev has hinted as much. Russia is openly demanding that at least a portion of the sanctions against it be lifted — only then will it agree to “save the world” from famine. The West has refused, calling the demand “blackmail” and the situation with the grain blockage a “war crime.” The Ukrainian authorities have also accused Russia of stealing grain from its occupied territories and attempting to export it through Crimea (claims that Russia denies).

That’s not quite accurate. There's always been hunger around the world; in recent years, it’s been fueled by the pandemic, which reversed a multiyear downward trend in world hunger. Different international organizations have different estimates of how many people don't have enough to eat, but according to data from the UN, there were about 760 million people facing food insecurity in 2020.
Information on global hunger in the last year is not yet available, but the UN’s World Food Programme (WFP) recently published estimates for some of the countries where the situation is most dire. If the war turns becomes a prolonged conflict, as it is currently expected to, the WFP projects the number of food insecure people to increase by 17 percent — but 276 million to 323 million people in 81 countries.
But if Russia wants, it will have every opportunity to cause a disaster that will make even the current projections seem small. Russia is a world leader not only in grain exports but also in fertilizer and natural gas, and if it wants, it will be able to block all three key export lines, leading to an unprecedented food crisis.
If that happens, we'll have to hope that even the most severe food crisis is a crisis of distribution rather than one of production. After all, the number of calories produced by the global food system is exponentially higher than the number of calories humanity needs, but a significant proportion of that output is used for other industries (such as biofuel), and almost half of is is used to feed livestock. In the event of a protracted crisis, it’s those industries that would have to take a hit to make room for the needs of starving people.
