Reactive nitrogen (Nr) is essential for agricultural production and human nutrition, but also leads to Nr pollution. Nr pollution induced by food are created by millions of diverse producers/products worldwide with vastly different climates, soils and agronomic management.
To identify effective solutions under this heterogeneity, we presented a methodological framework to build the evidence-based nitrogen (N) indexes for global food at varying levels of detail and complexity. It would provide a comprehensive assessment of Nr loss for individual food items, a robust prediction of associated environmental and socioeconomic impacts to make global agriculture more sustainable, less polluting and more profitable.
