Approaching a dynamic view on the availability of mineral resources: What we may learn from the case of phosphorus?

► The Hubbert curve is an inadequate model for predicting global phosphorus reserves. ► Physical scarcity and economic scarcity have to be distinguished. ► There is geological evidence for economically mineable phosphorus for centuries. ► There is incomplete knowledge about total phosphorus resources/reserves which are dynamic figures. ► The complexity of sustainable P management necessitates a transdisciplinary approach.
