Lettuce is national security by Sabine Fischer

For decades, governments have treated food as a commodity, agriculture as an economic sector and supermarkets as temples of endless abundance. We became so comfortable with the miracle of global distribution that we forgot a rather embarrassing detail: food does not grow on supermarket shelves, and a nation cannot eat a shipping forecast.

Now extreme weather is disrupting harvests, geopolitical conflicts are shaking trade routes, and global supply chains are demonstrating their extraordinary capacity to collapse at precisely the moment we need them most. Yet the political establishment continues to behave as though food security means negotiating another trade agreement, signing another import contract and crossing its fingers that somewhere on the planet the rain will arrive on time.

This is not food security. It is national dependence wearing a business suit. The local food revolution must therefore stop being marketed as a fashionable ecological hobby for urban middle classes who enjoy expensive organic tomatoes and photographs of community gardens. It is becoming a matter of national resilience, economic survival and, ultimately, defence. A country that cannot feed its population when international distribution breaks down is not strategically independent. It is simply lucky until its luck runs out.

Consider the absurdity of our present arrangements. Food may travel thousands of kilometres, cross several borders, pass through centralised warehouses and depend on fuel, refrigeration, digital logistics and political stability before reaching a family’s kitchen. The system is efficient when everything works. But efficiency without resilience is an invitation to disaster. A blocked shipping route, a fuel crisis, a cyberattack, a prolonged drought or a regional war can turn apparent abundance into an expensive shortage remarkably quickly.

And when that happens, people do not eat efficiency reports. The pandemic offered a warning. Conflicts have reinforced it. Extreme weather is making the warning harder to ignore. Droughts, floods, heatwaves and shifting growing seasons threaten agricultural production across regions that the global market has come to treat as interchangeable suppliers. They are not interchangeable when several major producers suffer simultaneous crop failures or when exports are restricted to protect domestic populations.

A global food system built around concentration and maximum short-term profitability can become dangerously fragile. The answer is not to abandon international trade or pretend every country can grow every crop. That would be economic nonsense. The answer is to stop confusing global cooperation with total dependence on distant suppliers.

Food resilience begins at the municipal level. Cities and towns should identify what they can produce locally, which surrounding farms can supply them, what storage capacity they possess and how food would reach vulnerable residents during a prolonged emergency. Municipal authorities should protect agricultural land from speculative development, support local farmers, encourage cooperatives, invest in regional processing facilities and create distribution networks that do not collapse when a single warehouse or transport corridor fails.

Schools, hospitals, public kitchens and care homes can become dependable customers for regional producers. Rooftops, vacant plots, community gardens and suitable urban spaces can supplement production, although nobody should pretend that a few lettuce beds will feed a metropolis. Serious local food policy requires serious agriculture, infrastructure, land management and investment.

And yes, it requires governments to pay farmers properly rather than treating them as disposable suppliers whose livelihoods can be sacrificed whenever supermarket chains demand lower prices.

Here lies the political scandal: governments spend enormous sums discussing national security while leaving a fundamental element of it exposed to market concentration, environmental disruption and logistical failure. We protect borders, discuss military readiness and worry about hostile powers, yet frequently neglect the agricultural foundations that allow a society to function in the first place.

What exactly are soldiers defending if the population cannot reliably obtain food? National defence must expand its understanding of security. It should include seed diversity, soil health, water management, agricultural knowledge, regional storage, resilient electricity supplies and the survival of small and medium-sized farms. These are not sentimental rural concerns. They are strategic assets.

There is also a democratic dimension. Communities with stronger regional food networks possess more choices when international markets become unstable. They can keep more economic value circulating locally, strengthen relationships between producers and consumers, and reduce the distance between a shortage and a practical response. Local production will not eliminate food inflation or protect every harvest from climate disasters, but diversified systems can provide alternatives when one part of the chain fails.

The transition will not be cheap. Building storage, supporting farmers, improving irrigation and establishing processing facilities requires public money and long-term planning. But resilience always costs something before a crisis. Dependence costs considerably more during one. The real revolution is not about replacing every imported banana with a patriotic apple. It is about designing a food system in which international trade provides opportunity rather than holding entire populations hostage to its uninterrupted operation.

The next great security crisis may not begin with tanks crossing a border. It may begin with empty warehouses, failed harvests, interrupted deliveries and governments discovering that their supposedly sophisticated food systems have no adequate backup. A nation cannot eat its stock market. It cannot digest a trade agreement. And it certainly cannot survive on political speeches about strategic autonomy. The defence of a country begins long before the first shot is fired. Sometimes, it begins with the farmer down the road.
