文摘
We live in a global phosphorus (P) system paradox. P access is becoming increasingly limiting, leading to food insecurity but at the same time an over-application or abundance of P in many agricultural and urban settings is causing environmental degradation. This has been recognised in the academic literature and at regulatory levels, but swift action and multi-level cooperation of all stakeholders is required to ensure the economically, environmentally and socially responsible use of P. To provide foundations for future cooperation, a conceptual model describing the elements of P need, P availability and P use in different systems and at different scales was developed during the Young Scientists Workshop in P Week 2014 in Montpellier, France. Here we describe our extended conceptual model and a theoretical P balance calculation tool for describing multi-scale P balances and imbalances to impartially advise all stakeholders on more sustainable P use across the world.
