The Strait of Hormuz Proves Fossil Fuels Are Essential for Food Security

Why It Matters

Fertilizer supply constraints directly threaten global food security, especially for low‑income regions, while highlighting the trade‑off between climate mitigation and agricultural productivity. Policymakers must balance emission reductions with ensuring affordable access to essential agricultural inputs.

Key Takeaways

• Hormuz Strait blockage threatens 25% of global fertilizer shipments.
• Fertilizer price rise could push 45 million more into hunger.
• Half of global calories rely on natural‑gas‑based fertilizers.
• Aggressive emission cuts may increase food costs, harming vulnerable farmers.
• Historical data shows fertilizer access drives greater food gains than climate mitigation.

Pulse Analysis

The Strait of Hormuz, linking the Persian Gulf to the open ocean, handles an estimated 25% of the world’s nitrogen fertilizer trade. When vessels are delayed or rerouted, shipping costs surge and delivery timelines extend, creating a ripple effect across commodity markets. Fertilizer producers, many of which rely on natural‑gas‑derived ammonia, face higher feedstock prices, a pressure that quickly translates into higher farm input costs for growers from the United States to sub‑Saharan Africa. This logistical shock illustrates how geopolitical events can outweigh climate‑driven supply concerns in the short term.

Rising fertilizer prices have immediate implications for food security. A 15‑20% price jump can erode profit margins for smallholders and raise retail food prices, pushing an estimated 45 million people toward acute hunger, according to UN estimates. While climate advocates warn that carbon emissions jeopardize agriculture, the data show that modern yields are heavily dependent on synthetic inputs powered by fossil fuels. The contrast between long‑term climate risks and acute supply disruptions underscores the need for a nuanced risk assessment that separates gradual temperature effects from sudden geopolitical shocks.

Policy choices now face a stark trade‑off. Aggressive carbon pricing or rapid decarbonisation of fertilizer production could inflate costs for farmers, especially in regions lacking mechanisation and access to credit. Conversely, investments in resilient supply chains, diversified feedstock sources, and targeted subsidies for fertilizer can safeguard harvests and keep food prices stable. Balancing emission targets with food‑security objectives will require coordinated action among governments, industry, and international bodies to ensure that climate ambition does not inadvertently exacerbate hunger.
