Has the war in ukraine sparked a global food crisis? (bbc - the inquiry) 

BBC – The Inquiry produced a video stating that key export routes are blocked due to blockades by Russia against Ukraine as part of Russia’s war strategy. Governments are nervous. Dozens of countries stopped or restricted international food sales. Senior research fellow David Laborde said, “For example, Millions of people depend on Indonesia for palm oil (a basic food product); we have seen export bans on wheat from Central Asia, Malaysia has banned poultry exports to Singapore.” Underpinning all of this is food security. “It is a quantity concept—the amount of grains available; do you have the economic means to buy this food—the price question; do you have daily availability or will there be lean times?”
