Even the slightest perceived risk can drive up fertiliser prices, stall shipments and cause a seismic shift in food price inflation.This food insecurity scenario is not new: COVID-19 pandemic disruptions and the war in Ukraine drove fertiliser prices to record highs, exposing how dependent we have become on a handful of export hubs and bottlenecked transport routes.About 80 percent of fertiliser used across sub-Saharan Africa is imported, often at prices much higher than in Europe due to freight, financing and logistics.
