Warning on global food supply - a podcast by BBC World Service

One of Ukraine's biggest food producers has warned of the impact of war on food supply. Dr John Rich is the chairman of MHP, and tells us further Russian advances in Ukraine could prevent farmers from sowing seeds for this year's crops. And we consider the importance of Russia and Ukraine's food production to the global food chain with Arnaud Petit, director of the International Grains Council. Also in the programme, the BBC's Ed Butler explores how much the Ukraine war is actually costing Russia in terms of munitions, equipment losses, sanctions and isolation. Plus, we get a Russian perspective on the events of the last two weeks from Andrei Kolesnikov, who is chair of the Russian Domestic Politics and Political Institutions Program at the Carnegie Moscow Center.

Today's edition is presented by Fergus Nicoll, and produced by Faarea Masud, Ivana Davidovic and Nisha Patel.(Picture: Last year's harvest in Ukraine. Picture credit: Getty Images.)
