Global Food Prices at Record Highs: A Looming Crisis?
Global food prices have ascended to record levels, surpassing even the peaks seen after the 1970s energy crisis. This surge, once inflation is accounted for, was initially triggered by Middle Eastern conflict. Now, a new, potentially more severe food shock looms, as turmoil in Iran propels fuel, fertilizer, and pesticide costs skyward.
Farmers, confronting escalating expenses, are likely to scale back planting in the coming weeks. This reduction in cultivated land directly foreshadows future shortfalls and, consequently, higher food prices later in the year. While this trend is already evident, the ultimate severity of the crisis hinges on numerous variables. These include the duration of ongoing conflicts and the impact of global warming-fueled extreme weather events on crop yields.
Matin Qaim of the University of Bonn in Germany warns of the “potential for this to develop into a major crisis for poor and hungry people.” Similarly, Tim Benton from the University of Leeds in the UK describes the situation as “a bit of a perfect storm, and there isn’t any easy way out of this.” He further notes that even if immediate solutions were found, recovery would still require considerable time, echoing the challenges observed in post-COVID reconstruction.
Global food prices, after a prolonged decline following their 1970s peak, have been on an upward trajectory in real terms since the early 2000s. They are now approaching that historical record. Climate change plays a significant role, with escalating heatwaves, floods, and storms diminishing agricultural yields, sometimes leading to global food shocks akin to the one experienced in 2010. The COVID-19 pandemic and the conflict in Ukraine have also contributed to substantial price increases.
The increasing demand for biofuels further exacerbates the situation. Over 5 percent of food calories are now diverted into fuel production rather than human consumption. While some governments acknowledge the need to phase out food-based biofuels, a recent report indicates that a substantial 92 percent of biofuels will remain food-based by 2030. The current geopolitical situation, involving escalated tensions with Iran, is creating significant shortfalls in essential raw materials vital for both the production and distribution of food. Fuel is a primary concern; diesel powers agricultural machinery, along with the vast network of ships and trucks that transport food. Therefore, an increase in oil prices inevitably translates to higher costs at the supermarket.
The Fertilizer Crisis
Fertilizers are indispensable for global food supply. Qaim emphasizes, “If we stopped using mineral fertilizer completely worldwide, we would probably see half of the world starving.” The production of nitrogen fertilizers involves a reaction between hydrogen and atmospheric nitrogen to create ammonia, a process reliant on natural gas for both hydrogen supply and the energy required. Ammonia is then typically converted into urea, a solid form convenient for transportation.
Qatar, possessing extensive natural gas reserves, has emerged as a major fertilizer producer. According to Anthony Ryan of the University of Sheffield, the country supplies 15 percent of the world’s urea and 50 percent of urea traded internationally. However, the flow of this urea through the Strait of Hormuz, a narrow maritime passage between Iran and the Arabian Peninsula, has been severely restricted. This disruption extends to other nations. Countries like India, Bangladesh, and Pakistan, which rely on Persian Gulf gas for their domestic fertilizer production, are now facing factory shutdowns. With natural gas production facilities in the region damaged by conflict, these supply chain disruptions could persist for years. Compounding these issues, a significant fertilizer plant in Australia has also ceased operations due to an accident.
Consequently, nitrogen fertilizer prices have already risen by over a third and are projected to increase further. Qaim suggests that a doubling of fertilizer prices could easily lead to a 20 to 30 percent increase in food prices. The impact is not confined to urea. Gulf nations such as Qatar and the United Arab Emirates are also key producers of sulfur fertilizers, essential in many regions, and sulfuric acid, required to convert mined phosphate into forms usable by plants.
Pesticides and Broader Economic Impacts
Pesticides, crucial for maintaining global food yields, are also facing price surges. This is particularly relevant as many pests are expanding their range and becoming more problematic with global warming. Pesticide prices are closely tied to naphtha, a fossil fuel derivative used to create a wide array of chemicals, including plastics integral to food packaging.
Analyst Jide Tijani of Argus Media reports that “Three of the world’s global naphtha-exporting hubs have been struck by drones so far in March.” These affected locations include the Ust-Luga port in Russia, recently targeted by Ukraine, as well as sites in Qatar and the UAE. These cumulative effects are projected to result in heightened prices for food and numerous other goods in the coming months and years.
Jason Hill at the University of Minnesota observes that “The number of markets that are being affected by this is staggering.” The problem extends beyond farmers facing increased costs for fuel, fertilizers, and pesticides, assuming they can even obtain them. Qaim highlights that if farmers are uncertain about profitability, they may opt for different crops or abandon planting altogether. Adding to the complexity, speculation and profiteering could further inflate prices, as noted by Jennifer Clapp of the University of Waterloo.
Assessing the Severity and Potential for Escalation
The severity of the unfolding crisis remains a subject of concern. Clapp points out that the significant food price spike in the 1970s was partly attributable to depleted global food reserves. While reserves are currently ample, this situation could change if conflicts persist, especially when combined with climate-change-induced extreme weather impacting yields. Clapp expresses a strong concern about the potential for the situation to “spin out of control and lead to a just as severe, if not a worse, crisis.” She adds, “If we have major climate events, it could definitely spiral into something much more severe.”
Qaim reiterates the global nature of these price increases, stating, “In the end, prices are global prices, and fertiliser prices are going up everywhere, and food prices are going up everywhere.” He stresses that “People who are at the lower spectrum of the income distribution are the ones that are most hurt, because they spend a lot on food. They can’t afford significantly rising food prices.”
Compounding these challenges, international aid has already seen substantial cuts, with further reductions likely. Benton notes that “When food prices go up and international aid is more needed, the availability of the money goes down and the price of what it can buy goes up.” Paul Behrens at the University of Oxford predicts that these economic pressures will lead to social unrest in the hardest-hit nations, citing historical patterns: “Every time that we’ve seen a food price spike in the past, you see this instability.”
Strategies for Mitigating Food Shocks
Measures exist to ameliorate the damage. Behrens highlights the “crazy way to produce energy” in Europe, where approximately 15 million loaves of bread are burned daily for biofuels. He asserts that governments, through subsidies and mandates, possess the authority to curtail biofuel production, thereby increasing food availability in the market. Qaim agrees that this action “could definitely help.”
Qaim advocates for an international agreement to automatically restrict food-based biofuel production when food prices reach excessive levels. However, he observes that nations are not even implementing such measures unilaterally. “We haven’t seen that happening in previous crises,” he remarks.
Conversely, Qaim anticipates that nations may opt to increase biofuel production in an effort to mitigate fuel price hikes, a move that could significantly amplify food price inflation on top of existing pressures. This trend is already emerging, with the US announcing an increase in the proportion of bioethanol in its fuels to manage price increases, and Australia considering similar measures.
The fundamental issue is that escalating biofuel production from food crops offers minimal benefit to fuel prices yet exerts a substantial impact on food costs. Hill provides an example from the US, where one-third of corn becomes bioethanol, which in turn supplies only a few percent of the gasoline market. This demonstrates “a disproportionate effect on food markets.”
Simon Donner of the University of British Columbia criticizes the policy of “blending more ethanol into gasoline” as a relic of the 1990s that fails to address air pollution or climate change. He suggests that the current oil price spike presents an opportunity for the US to transition to cleaner technologies like electric vehicles, but observes that the government is moving in the opposite direction. Hill emphasizes that other nations will be resistant to enduring similar predicaments again. “This is a major shock to the system and so, even if things were to go back to the status quo in terms of movement of ships and production and such, there is going to be, in everyone’s mind: ‘How can we produce a more resilient system?’,” he states.
Accelerating the adoption of renewable energy, electric vehicles, and heat pumps—essential for achieving net-zero emissions—will also render economies significantly less vulnerable to oil price fluctuations. Ryan further advocates for decoupling the chemical industry entirely from fossil fuels.
For nitrogen fertilizers, this necessitates production powered by electricity rather than natural gas. Ryan affirms, “Absolutely, you can do a no-greenhouse-gas-emissions ammonia.” He confirms that “The technology is there. What we don’t have is enough renewable electricity.” The concurrent rise in electricity demand for data centers supporting artificial intelligence suggests that this situation is unlikely to improve soon, unless the AI sector experiences a significant downturn.
Reducing Fertilizer Use and Shifting Agricultural Practices
In the interim, several strategies can reduce fertilizer consumption. Overuse is prevalent in many regions, leading to nutrient runoff into waterways and the conversion of excess into nitrous oxide, a potent greenhouse gas. Methods to curb overuse include precision farming technologies, crop rotation incorporating legumes, more effective manure management, and the breeding of plants that utilize fertilizers more efficiently.
Qaim clarifies that this approach pushes “towards more sustainable farming systems, but sustainable is not equivalent to organic.” He notes that a widespread shift to organic farming would result in substantial price increases due to reduced production and would necessitate increased deforestation to accommodate more farmland. Behrens calls for “a food system transformation,” which includes dietary changes, such as sourcing most protein from beans and legumes, which naturally fix nitrogen, rather than grain-fed meat. He concludes that such a shift “makes such a big difference.”
