In 2022, Families across Africa are paying about 45% more for wheat flour as Russia's war in Ukraine blocks exports from the Black Sea. Some countries like Somalia get more than 90% of their wheat from Russia and Ukraine. That's forcing many people to substitute wheat for other grains. But the United Nations is warning that the price hikes are coming as many parts of Africa are facing drought and hunger. (AP Photo/Jerome Delay, File)
