Our Food Depends on Oil. Sustainable Farming Is How We Change That

Every time oil prices spike, food prices follow. That link is not a coincidence; it is a design flaw baked into our agricultural system over the past 60 years. Sustainability in agriculture is not just a feel-good idea; it is a structural necessity. In this article, I want to explain how we got here, why the status quo is fragile, and what a realistic path toward sustainable farming actually looks like.

A phased transition over 10–20 years: realistic, not romantic


The Hidden Oil in Your Food

Most people do not realise how much of their food depends on fossil fuels, not just to transport it, but to grow it in the first place. The connection runs through fertilizers.

The dominant method for producing nitrogen fertilizer is the Haber-Bosch process, an industrial technique developed in the early 20th century that converts atmospheric nitrogen into ammonia. It is a remarkable feat of chemistry, and it now underpins roughly half of all food consumed globally (Nature, 2026). The catch: natural gas serves as both the feedstock and primary energy source, accounting for 70–80% of ammonia production costs (Nature, 2026). When gas prices go up, fertilizer prices follow, almost immediately.

This is not a theoretical risk. When the Strait of Hormuz was effectively closed in early 2026 following US-Israeli strikes on Iran, urea prices jumped by nearly 46% in a single month (Nature, 2026). Energy, fertilizers, and food are so closely intertwined that constraints in one area quickly cascade into the others (UNCTAD, March 2026). I covered the full Hormuz picture in a previous article, but the agriculture angle deserves its own conversation.

The deeper problem is structural: modern crops have been bred and optimised to perform well with heavy doses of synthetic nitrogen. They are, in a real sense, unable to grow organically at scale without a deliberate transition (IATP), because the farming methods that depend heavily on chemical fertilizers do not maintain the soil's natural fertility, creating a cycle of increasing dependency.

How Did We Get Here? The Green Revolution

We did not always farm this way. The shift happened remarkably fast, within a single generation.

The term "Green Revolution" was coined in the 1960s to describe a dramatic breakthrough in crop yields, driven by Norman Borlaug and colleagues who developed high-yielding dwarf wheat strains in Mexico in the 1950s. The new seeds, backed by the Rockefeller and Ford Foundations and spread across Asia and Latin America, were specifically engineered to respond to petrochemical fertilizers and controlled irrigation (IATP). By the 1970s, they had replaced traditional farming practices across much of the developing world. Cereal production tripled between the 1960s and 2000s, a genuine achievement that prevented widespread famine. But the trade-off was soil degradation, biodiversity loss, and deep dependency on chemical inputs (Britannica). The seeds worked brilliantly, but only within a system of oil, gas, and water that we assumed would always be cheap.

The problem was that this success was never really sustainable. Only 30–50% of applied nitrogen fertilizer is actually absorbed by crops (ScienceDirect); the rest leaches into waterways or is released into the atmosphere. Farmers end up needing ever more fertilizer just to maintain the same yields, year after year.

What Sustainable Farming Actually Offers

Sustainable farming is not simply about going back to ploughs and horse carts. It is about restoring the biological systems that make soil productive without constant chemical inputs.

The long-term benefits are significant:

  • Soil health: Organic farming builds soil organic matter over time. A meta-analysis of 74 studies found that organically managed soils sequester meaningfully more carbon than conventionally managed ones (PNAS, 2012).
  • Carbon sequestration: Organic systems are one of the highest-potential tools for reducing agricultural CO2 emissions, according to the IPCC's 2023 Synthesis Report, and a critical step toward a carbon neutral food system.
  • Biodiversity: Fields managed organically for years show lower pest pressure due to greater biodiversity and more complex ecological interactions, reducing the need for pesticides.
  • Resilience: A farm that draws its fertility from crop rotation, composting, and legume cover crops is not exposed to the price of natural gas in Qatar. That is circular economy thinking applied to agriculture: closing the loop on nutrients rather than importing them from a geopolitically volatile supply chain.
  • Long-term yield stability: The yield gap between organic and conventional farming narrows significantly over time, as soil health builds up. The transition period is the hard part, not the destination.


A Realistic Roadmap: How Do We Get There?

Getting back to sustainable farming does not mean dismantling the global food system overnight. It means building a credible transition pathway, one that takes the yield question seriously and does not pretend the shift is painless.

Here is what a realistic 10–20 year roadmap looks like:

Phase 1 (Years 1–5): Reduce dependency at the margins

  • Promote split fertilizer applications and soil testing so farmers apply only what is needed, not standard rates regardless of soil condition
  • Scale biological alternatives: nitrogen-fixing bacteria and cover crops can reduce synthetic nitrogen needs by 20–30% with relatively low disruption
  • Invest in farmer education and transition support; the biggest barrier is economic risk, not willingness

Phase 2 (Years 5–10): Restructure incentives

  • Redirect agricultural subsidies from yield-maximisation toward soil health outcomes. Most countries still pay farmers per tonne of output, which bakes in the fertilizer dependency
  • Price the environmental cost of synthetic nitrogen honestly, including its contribution to water pollution and greenhouse gas emissions
  • Support mixed farming systems that integrate livestock and crops, a cornerstone of nutrient cycling that industrial monoculture eliminated

Phase 3 (Years 10–20): Scale regenerative systems

  • Mainstream agroecological practices: crop rotation, agroforestry, composting at scale
  • Develop regional seed systems that perform well under lower-input conditions, reversing the Green Revolution's legacy of fertilizer-dependent varieties
  • Build a circular economy for organic waste: municipal food waste and sewage sludge (treated safely) are enormous untapped sources of natural nitrogen, currently landfilled or incinerated

None of this is fringe science. The EU's Farm to Fork strategy, for example, targets a 20% reduction in fertilizer use and 25% of farmland under organic management by 2030. Whether those targets are met is a political question. Whether the direction is right is not.


The Argument I Keep Coming Back To

We are not short of evidence that the current system is fragile. The 2022 Ukraine crisis disrupted fertilizer supply chains. The 2026 Hormuz crisis did it again, faster and harder. Each time, the same conclusion surfaces: a food system built on fossil fuels is a food system held hostage to geopolitics.

The real question is not whether we should transition toward sustainable farming. It is how fast, how fairly, and who bears the cost of a transition that the whole world benefits from. Those are political and economic questions, and as I argued in Sustainability Explained, they are only answerable when the right policy incentives are in place and institutions are strong enough to hold the course across political cycles. But they are only answerable if we stop treating the current system as the default and start treating it as a choice.

It was a choice, made in the 1960s, under pressure, with good intentions. We can make a different one.
