英文摘要	Agricultural trade and globalization pose new challenges for resource management and governance. In particular, many countries are dependent on imports of non-renewable mineral phosphorus (P) fertilizers for their agriculture. We propose a framework to assess the possible impacts of future disruptions in P resource availability by comparing countries’ P fertilizer use for export production (virtual P) to their existing domestic P resources (labile soil P stocks and phosphate rock reserves). We find that up to 26% of global P fertilizer use is linked to exported crop and livestock commodities, creating complex resource interdependencies across countries. Vulnerabilities to P resource shortage may be moderated by existing domestic P resources in some countries, which could mitigate either short- or long-term impacts of fertilizer trade disruptions. However, greater coordination among trade partners that acknowledges and manages multiple forms of mineral P interdependencies is needed to provide resilient access to P inputs for national food supplies globally. © 2021, The Author(s), under exclusive licence to Springer Nature Limited.
