The global disruptions caused by the war in Iran have brought renewed focus to the vulnerability of global fossil fuel supply chains. But what has received less attention is how the war also highlights the vulnerability of industrial agriculture supply chains reliant on massive amounts of chemical fertilizers and other inputs. Like oil and gas, these frequently travel long distances through turbulent waters.

A big advantage of renewable energy technologies like solar is that sunlight doesn’t have to pass through the Straits of Hormuz. The same can be said for many of the inputs required for agroecological and regenerative farming systems. The development of these approaches would see a food system that is not only less vulnerable to the supply chain shocks being felt today, but would be better for the environment, human health, and animals. It would be healthier, kinder, and more resilient.

A global economic recession and possible food shortages are looming as the war in Iran grinds on. While the devastating impact of the current conflict on people, their families, and communities must be foremost in our minds, the shock waves from the crisis are having system-wide impacts on energy supplies, cost of living, and food prices. As the seasons turn and farmers prepare to plant their crops, they are facing a new pressure: a sudden and critical rise in fertilizer and fuel costs.

As the price of petrol and diesel have skyrocketed since the closure of the Strait of Hormuz, so too have fertilizer costs due to shortages of urea and ammonia. A third of the world's key fertilizer chemicals pass through the Strait, and prices have risen steeply since the outbreak of war, with predictions that prices for nitrogen-based fertilizers like urea could roughly double if the war drags on. Alongside a rise in red diesel prices, agricultural profit margins are highly volatile.

The current war is heinous, but inadvertently it has created an inflexion point, a moment to rethink global distribution of goods, and our broken food system.

Farmers taking the financial hit will likely pass on the costs to the consumer, but this isn’t sustainable and undermines the financial, social, and environmental health of the global food system. What if we flip it? Could the Middle East War not only accelerate a shift to renewable energy but also reduce our dependency on fertilizer-hungry crops? Legumes such as beans and peas, which fix nitrogen in soils, root vegetables, soybeans, and hardy grains such as rye could be viable alternatives.

Since the Second World War, a burgeoning (and hugely profitable for a few) chemical industry has created food systems dependent on inputs such as fossil fuel-based fertilizer, pesticides, herbicides, and fungicides. While delivering greater crop surplus, industrial farming has brought new problems: algal blooms, less wildlife and pollinators, monocultures, local air pollution, global climate change, and the loss of small-scale farming and farmers.We’ve reached a tipping point; we overproduce food, a third of which is wasted, and too many people are eating too much of the wrong types of food. Noncommunicable diseases such as cardiovascular disease and diabetes are becoming a much bigger health burden than infectious diseases. Meanwhile, entrenched inequalities mean that, despite a global food surplus, millions of people go hungry every day, and 2.6 billion people........
