Climate Change Could Worsen Supply Chain Turmoil

Academics say the effect of these disasters, and of higher temperatures in general, will be particularly obvious when it comes to food trade. Some parts of the world, like Russia, Scandinavia and Canada, could produce more grains and other food crops to feed countries as global temperatures rise.

But those centers of production would be farther from hotter and more densely populated areas closer to the Equator. Some of those regions may struggle even more than they do now with poverty and food insecurity.

One danger is that increasing competition for food could encourage countries to introduce protectionist policies that restrict or stop the export of food, as some have done in response to the pandemic and Russia’s invasion of Ukraine. These export restrictions allow a country to feed its own population, but tend to exacerbate international shortages and push up food prices, further aggravating the problem.

The World Trade Organization, citing the damage that protectionist policies could pose, has urged countries to keep trade open to combat the negative effects of climate change.

In a 2018 report, the W.T.O. pointed out that the global food trade was particularly vulnerable to disruptions in transportation that might occur as a result of climate change, like rising sea levels threatening ports or extreme weather degrading roads and bridges. More than half of globally traded grains pass through at least one of 14 global “choke points,” including the Panama Canal, the Strait of Malacca or the Black Sea rail network, the report said.

Ngozi Okonjo-Iweala, the W.T.O.’s director general, has described trade as “a mechanism for adaptation and resilience” that can help countries deal with crop failure and natural disasters. In a speech in January, she cited economic models estimating that climate change was on track to contribute to severe malnutrition, with as many as 55 million people at risk by 2050 because of local effects on food production. But greater trade could cut that number by 35 million people, she said.
