Global food threat: What to do about Russia's blockade of Ukrainian exports?

We ask what it would take to reopen the Black Sea and about alternatives, such as the land route through Poland suggested by the EU agriculture commissioner. 

But Moscow has ideas of its own, warn the Ukrainians. They accuse the Kremlin of stealing their land, stockpiles and farm equipment with the long-term aim of playing the generous benefactor who feeds the planet. 

It's not just about Ukraine and the developing world. How to ensure food security for all? What lessons have we learned from global warming, population pressure, supply chain disruptions during Covid and now war in Europe's breadbasket?
