Managing
reactive nitrogen (N<sub>r</sub>) to achieve a sustainable
balance between production of food, feed and fiber, and environmental
protection is a grand challenge in the context of an increasingly
affluent society. Here, we propose a novel framework for national
nitrogen (N) assessments enabling a more consistent comparison of
the uses, losses and impacts of N<sub>r</sub> between countries, and
improvement of N<sub>r</sub> management for sustainable development
at national and regional scales. This framework includes four key
components: national scale N budgets, validation of N fluxes, cost-benefit
analysis and N<sub>r</sub> management strategies. We identify four
critical factors for N<sub>r</sub> management to achieve the sustainable
development goals: N use efficiency (NUE), N<sub>r</sub> recycling
ratio (e.g., ratio of livestock excretion applied to cropland), human
dietary patterns and food waste ratio. This framework was partly adopted
from the European Nitrogen Assessment and now is successfully applied
to China, where it contributed to trigger policy interventions toward
improvements for future sustainable use of N<sub>r</sub>. We demonstrate
how other countries can also benefit from the application our framework,
in order to include sustainable N<sub>r</sub> management under future
challenges of growing population, hence contributing to the achievement
of some key sustainable development goals (SDGs).
