ADDIS ABABA, Ethiopia, May 20 2026 (IPS) Sharp surges in energy, fertilizer, and food prices triggered by the ongoing conflict in the Persian Gulf strikingly illustrate the deep interconnections between geopolitical conflict, food insecurity, and the fragility of fossil fuel–dependent food systems. Besides carrying roughly 20 million barrels of oil per day (about 27 percent of global oil exports), the Strait of Hormuz also handles 20–30 percent of internationally traded inorganic fertilizers, which uses natural gas as a key ingredient in its production. Its closure has immediately disrupted the flow of these essential commodities, triggering sharp price spikes in fuel and key agricultural inputs.
This situation demonstrates how geopolitical instability can rapidly disrupt essential agricultural functions under current input-dependent, industrial production systems that rely heavily on external energy and supply chains. This crisis highlights, more clearly than ever, a critical reality: food systems tied to fossil fuels are inherently unsustainable, continually undermine food sovereignty, and disproportionately affect farmers, particularly smallholders in low- and middle-income countries (LMICs). World Food Programme estimates warn that, if the conflict continues, the soaring oil, shipping and food costs will push an additional 45 million people into acute hunger, driving the global total beyond its record 319 million 1 . Reducing food systems’ reliance on fossil fuels and external inputs is essential to strengthen our collective resilience to future shocks. The truth is that fossil fuels courses through every stage of the food system – from fertilizers and pesticides to processing, preservation, transportation, packaging, food waste disposal, and even food preparation. Moreover, entrenched economic and political structures lock in this fossil-fuel dependence through massive subsidies and price protections – estimated at over $1 trillion in recent years 2 . Food systems account for at least 15 percent of total fossil fuel use – mostly through synthetic fertilizers 4 – but also to power machinery and vehicles, and generate electricity and heat for key processes like irrigation, grain drying, livestock housing, and food storage. Agroecological approaches to food production offer an alternative to reduce our dependence on fossil fuels while still meeting the needs of a growing global population. This supports a transition from energy-sink systems to regenerative ones, radically enhancing food systems’ resilience in the face of escalating geopolitical instability and environmental vulnerability.
Agroecology is based on natural processes and local resources for sustainable soil fertility. Crucially, many of these practices draw directly from indigenous knowledge systems, where local communities have long maintained soil health through time. Practical steps include the use of organic fertilization (often blended with minimal synthetic inputs), efficient soil microorganisms, nitrogen-fixing plants, and soil health practices like crop rotation, cover cropping, intercropping, reduced tillage, and crop-livestock integration.
Research consistently shows that agroecological approaches – such as farm diversification and tree integrated systems – outperform conventional systems in climate resilience, nutrient cycling, and soil health 5,6 , often while boosting yields 7-9 . Agroforestry also provides a source of wood fuel, making it a valuable alternative during fossil fuel shortages and price spikes.
Examples can be found worldwide. Peruvian cocoa farmers are using bokashi and bio-oil amendments to restore soil organic matter, regenerate microbial activity, and enhance nutrient cycling 10 . In Vietnam, rice-fish coculture systems optimize nutrient cycling, curb pests, and diversify outputs – lowering costs while stabilizing farmer incomes 11 . Ethiopian farmers practicing wheat-fava bean rotations are cutting fertilizer needs while improving soil structure and building long-term fertility11. India’s agroecology programme, ‘Zero Budget Natural Farming (ZBNF)’, delivers biodiversity benefits while more than doubling farmers’ economic profits and maintaining comparable crop yields, than chemical-based farming 12,13 . Other farm-level steps to curb fossil fuel dependence include integrating renewable energy sources for on-site generation and operations – like solar panels, biogas digesters, and wind turbines; solar water pumps, adopting fuel-efficient engines and draft animals; and embracing practices such as minimum tillage, precision irrigation, integrated pest management, and low-input crop-livestock systems. More fundamentally, shifting from global, industrial commodity chains toward territorial, agroecological food networks can relocalize production, processing, and consumption – shortening supply chains and reducing energy-intensive operations. Shorter, localized supply chains reduce reliance on long-distance transport, lower packaging demand, and promote reusable packaging systems, thereby decreasing fossil fuel consumption. These efforts can be reinforced by complementary practices that strengthen food sovereignty, such as home gardens and urban agriculture. Crucially, agroecology also aligns with reduced production of ultra-processed foods – among the most energy-intensive products – helping to curb fossil fuel use while potentially improving public health.
In the short term, it is crucial that the allocation of emergency funds are earmarked to procure or purchase organic alternatives to synthetic fertilizers, particularly in the most affected regions. Longer-term, it is necessary to reduce structural barriers to farmers’ adoption of these agroecological approaches including reforms to agricultural subsidies and strengthening support for technical assistance and local governance.
