Pursuing sustainable nitrogen management following the “5 Ps” principles: Production, People, Planet, Policy and Partnerships

Abstract

Nitrogen (N) is an essential nutrient to support life, but if poorly managed, can adversely affect the environment, ecosystems and human health. The global challenge of achieving food security with minimal ecosystem degradation and human health impacts hinges on sustainable N management, which goes beyond farm level and requires concerted efforts from a range of stakeholders. While various metrics have been developed to inform N management, most of them focus on one or two stakeholders only. Few efforts have tried to integrate N metrics to derive a coherent set of actions for all stakeholders. Here we propose the “5 Ps” principles (Production, People, Planet, Policy and Partnerships) that sh..
