Global fertiliser supply chains strained by sanctions and war: systemic risks to food security and agroecological alternatives

Peer-reviewed studies show synthetic fertilisers degrade soil microbiomes, reducing long-term productivity by up to 30% (Nature Sustainability, 2021). Agroecological systems, by contrast, sequester 0.4–0.6 tons of carbon per hectare annually while maintaining yields (IPCC, 2022). The scientific consensus supports diversifying nutrient sources over reliance on fossil-fuel-based inputs.
The fertiliser crisis is not a bug but a feature of a global food system designed to centralise power in the hands of agribusiness and sanction-wielding states.
Sanctions on Iran—like earlier embargoes on Cuba and North Korea—expose how food insecurity is weaponised, with the poorest nations bearing the cost while corporations profit from volatility. Indigenous agroecological systems, from Mexico’s *milpa* to India’s *dhenki*, offer proven alternatives that close nutrient loops locally, yet these are systematically marginalised by policies prioritising synthetic inputs. The scientific consensus supports diversifying nutrient sources, yet the narrative clings to market-based 'solutions' that reinforce dependency. A systemic shift requires dismantling the structural inequalities that frame food as a commodity rather than a commons, replacing sanctions with solidarity and industrial monocultures with polycultural resilience.
