Ida piles on climate threat to U.S. food supplies

As drought continues to punish food producers throughout the American West, Hurricane Ida has reminded us that the very opposite problem — raging storms and floods — not only imperils crop production but can devastate global food distribution networks.

Centralized shipping networks are vulnerable to disruption — one storm in Louisiana can paralyze 60% of U.S. grain exports to the rest of the world.

It’s the same lesson we learned from the devastating impacts of COVID-19 and cyberattacks on major meat processing facilities, which showed that consolidation has made the U.S. meat industry fragile.

Again we’re left asking in the wake of disaster: When are we going to get serious about shifting the paradigm?

Hurricane Katrina caused $900 million in agricultural damage, inundating swaths of cropland, killing millions of chickens and thousands of cattle, and forcing dairy producers to dump vast quantities of milk. Hurricane Maria decimated 80% of Puerto Rico’s agricultural economy, which is still trying to recover.

The coming days will reveal the extent of losses to livestock and the bumper crops of cotton, corn and soy that were growing in Louisiana and surrounding states before Ida struck, but the infrastructure damage was immediately apparent: In a matter of hours, the Category 4 hurricane impeded exports from one of the busiest agricultural ports in the world.

When Ida pummeled the Louisiana coast, it destroyed docks and export terminals used for agricultural trade, crushed grain storage and processing facilities, shut down agrochemical plants and paralyzed major transport routes for soybeans and corn along the lower Mississippi River.

The Gulf of Mexico is the world’s largest grain export shipping market. Storms that rip through this region also threaten the vital barge transportation system that runs along the Mississippi river, linking Midwestern farmers to the port. More than half of U.S. grain exports are hauled down the lower Mississippi and loaded onto ships that travel through the Gulf — many of them enroute to Asia.

Ida has reminded us that this region, a lynchpin of the global food supply chain, is vulnerable at a time when global grain supplies are shrinking and demand from China is strong. It serves as a warning to Congress and the Biden administration, who need to examine the weaknesses of a food system that has become so heavily dependent on long-distance trade. Our lawmakers must investigate what it will take to build flexibility and redundancies into food distribution networks, while continuing to support sustainable, climate-resilient farming and incentivizing smaller-scale local food production.

The U.S. imports more than half of the fruit we consume and a large share of our vegetables. Overall, U.S. farmers export more than 20% of everything they produce. There’s no getting around the fact that vulnerable distribution networks translate into longterm food insecurity.

As President Joe Biden and Congress begin to invest the funds from their gargantuan infrastructure bill, they must do so with an eye toward resilience and redundancy, especially for shipping networks.

In the long term, we must remember that climate change is, fundamentally, a disturbance in hydrology. Increasingly, we are living in a world with too much water in some regions, and far too little in others; a world where the pressures to adapt to climate change are becoming ever greater.
