The Graphic Truth: Are we headed for a food price crisis?

Global food prices have jumped by one-third since a year ago, as a result of pandemic- and climate-related supply chain disruptions as well as export restrictions. While the situation isn't (yet) as bad as in 2007-2008, when sharp increases in food prices triggered civil unrest across many parts of the world, the trend isn't a good one. Food price inflation and, in more extreme cases, the risk of famine will only exacerbate the challenges of economic collapse and mass unemployment left behind by COVID. We take a look at how the global prices of five key food products have changed since the pandemic began.

What We're Watching: Biden-Putin summit, North Korea's food crisis, Tunisian constitutional reform

No fireworks in Geneva: Russian President Vladimir Putin and US President Joe Biden sat together for four hours on Wednesday, and as we anticipated in Signal, both leaders agreed to continue to cooperate where they can and to continue to pursue their national interests, as they see them. They're now expected to work together on nuclear disarmament. That's good, since these two countries still account for most of the world's atomic weapons. They're also open to exchanging prisoners, a welcome development. But more importantly, Biden and Putin set down their red lines: for the US it's the critical infrastructure that should be off-limits from hackers, and for Russia it's further expansion of NATO. US sanctions will remain in place. If the summit was a "success," it's only because expectations were low. Curb your enthusiasm indeed. For now, we'll be watching to see whether US-Russia ties enter a period, however brief, of the stable and predictable relations Biden says he wants, or if some new controversy triggers a new war of words.

The Graphic Truth: Has climate change hurt or helped farmers?

Over the past half century, climate change has had an immense impact on the farmers who produce the food we eat. A new study by Cornell University shows that global warming has knocked 21 percent off of global agriculture productivity growth since 1965, equivalent to seven years of normal growth if humans had not polluted the planet. But not all countries have been affected in the same way. Farmers in warmer parts of the world have been hit hard as conditions grow more arid, but sub-polar regions in Canada or Siberia are now actually better for agriculture because they are not as cold as they used to be. Here we take a look at how climate has affected farming productivity growth around the world.
