Report Details How Climate Crisis Fuels Crop Failure Risk in Global Breadbaskets

The climate emergency is sharply increasing the risk of crop failure in regions that produce an outsized share of the world's staple food grains, according to a report published Tuesday that warns of "serious threats to Europe, the NATO alliance, and global stability" if cooperative resilience initiatives and other mitigation strategies aren't pursued.

The report, "Global Breadbaskets: Food System Resilience as a Strategic Imperative," was published by the Center for Climate and Security—part of the Council on Strategic Risks, a Washington, DC-based security policy think tank—and the Woodwell Climate Research Center, an independent nonprofit located in Falmouth, Massachusetts.

"Geopolitical fragmentation, conflict, extreme weather, and global aid cuts already strain food security. Meanwhile, climate change is increasing the likelihood of crop failures in the American, European, and Asian breadbaskets, which produce most of the staple crops underpinning global food security," the report states.

The publication follows an April report from a pair of United Nations agencies on how extreme heat is impacting food production and food security around the planet. The new report includes a storymap that explores climate change-driven threats to wheat, rice, and maize (corn) crops in France, Germany, and India—three of the world's "global breadbaskets."

The analysis' authors note that compared with 2010 threat levels, by 2040, "the risk of a given year’s crop failing is projected to grow roughly twofold for Indian wheat and German maize, roughly threefold for French wheat, roughly fourfold for French maize, and roughly sixfold for Indian rice, with sharp increases in critical producing regions."

Climate-driven extreme heat "not only threatens crops, but also the laborers and infrastructure that translate them into food security," the report continues. "Extreme heat is projected to reduce the suitability of 15-40% of India’s rain-fed rice-growing regions by 2050, and to reduce physical work capacity during the average growing season to as little as 40% of 2000-era levels by 2100."

"By 2040, southwestern France will average up to 16 additional days per year above 35°C (95°F), exceeding thresholds that reduce yields, impact grain quality, and cause heat stroke," the paper warns. "Extreme heat also threatens to damage or disable road and rail networks critical to food transportation, agricultural machinery, civil defense, and military mobilization."

The publication also states that global breadbasket failures in Europe "could open rifts for Russian meddling, fuel instability in key partners, and elevate food production as a geopolitical lever."

The Council on Strategic Risks operates within the transatlantic security policy community, whose work often overlaps with NATO's interests.

“We have plenty of examples of how crop failures can contribute to political instability, from the French Revolution to the Arab Spring," Center for Climate and Security deputy director and report lead author Tom Ellison said Tuesday in a statement. "In today’s environment, global breadbasket failures could strain NATO priorities, prompt unrest in key countries, and upend trade relationships."

Woodwell Climate Research Center scientist and report co-author Alexandra Naegele warned that “climate change doesn't just threaten crop yields and grain quality—it destabilizes entire food systems, from labor and livestock to food storage and transport."

"Quantifying these climate-driven risks is an essential step toward building resilient food systems and safeguarding global food security," she added.

The report recommends steps countries—specifically members of the European Union and NATO—can take to mitigate risks to food security, including strengthening cooperative resilience, anticipating instability and hybrid warfare, supporting strategic and vulnerable partners, coordinating trade responses, and investing in agricultural research and development.

"Amid climate change, geopolitical uncertainty, food shocks from the war in Iran, and Russian hybrid warfare, investing in a resilient food system isn’t in competition with security—it’s a key part of it," Ellison stressed.

Monica Caparas, a scientist at the Woodwell Climate Research Center and report co-author, said, "Understanding and preparing for breadbasket failures is both a national security priority and a humanitarian imperative—one that can help protect lives, reduce instability, and strengthen food resilience before a regional shock becomes a wider crisis."
