The ban on the export of food and fertilizer from Russia was introduced until August. But Syria and Egypt have nothing to worry about, the ban only applies to unfriendly countries, which do not include African countries. Russia will not allow a humanitarian crisis in Africa related to food shortages, because it knows how much many of the countries of the black continent depend on food supplies from Russia.
Russian farmers invested heavily in the grains sector ever since 2014 and these sort of export bans can be self-defeating for them. African nations alone can't make up for all the shortfall in demand coming from Europe. BTW, the rise in food prices is impacting everyone. And it will have political consequences. Here in India, the ruling party is now facing a lot of criticism for failing to control the rising inflation rate. And even in the US, elections are due in less than 7 months, and the GOP seems to be in a position to wrest back the control of the senate.
As far as I know, Russia imports seeds for agriculture from other countries.
In addition, agriculture uses imported harvesting equipment, as well as Russian equipment, but with the presence of foreign components.
Some foodstuffs Russia does not produce in the required quantity to provide for its population - for example, beef (in India, as far as I know, cows are not eaten, and in Russia this is one of the main sources of meat).
A similar situation with the production of milk - Russia imports the semen of bulls manufacturers. Without semen imports, cows will produce less milk and the milk will have a low percentage of fat.
In addition, Russia is now in a critical situation with the production of railway cars and trains. Even with a good harvest, it is not a fact that the grain will be able to be delivered to the granary.
In addition, bans have been introduced on the entry of Russian ships into many seaports. This will lead to a significant increase in the cost of the transportation process.
All this suggests that agricultural production in the Russian Federation will decline.
The volume of food exports from Russia will also decrease.
Selling prices for Russian agricultural products will rise.
