  • Existing datasets of nitrogen (N) balance in agriculture are often discrepant. Comparing 13 of them regarding five metrics (fertilizer application, manure application, biological N fixation, atmospheric deposition, and N harvested as crop products) over 1961–2015 reveals why. Recommendations for improving N quantification and an N budget benchmark dataset are also proposed.

  • Climate change has already impacted nitrogen use and crop production. Nitrogen and climate scientists have to work together to understand future agricultural nitrogen use and adapt nitrogen management in a changing climate.

  • Determining the safe operating space for sustainable food production depends on the interactions of multiple processes within the Earth system. Expert knowledge provides critical insight into how these processes interact that improves Earth system modelling and our understanding of the limits of global food production.

  • Quantifying the long-term (LT) response of crop yields to nitrogen fertilizer is critical to improving nutrient management practices. Based on 25 LT field experiments, this study develops a generic LT nitrogen response function for global cereals to characterize the yield impacts, associated LT economic benefits and external costs of changing nitrogen inputs.

  • Population growth and associated increases in food and feed demand may drive cropland expansion at the expense of natural area and biodiversity, as well as higher greenhouse gas emissions. This study shows how a more efficient and better targeted use of phosphorus is key to avoiding such environmental problems.

  • The incorporation of saturated bioisosteres of phenyl rings has emerged as an appealing strategy in drug-discovery programmes. However, stereocontrolled access to these sp3-hybridized skeletons remains elusive. Now, the enantioselective synthesis of bicyclo[2.1.1]hexanes has been achieved through a Lewis-acid-catalysed [2 + 2] photocycloaddition, making it possible to obtain different drug analogues with improved properties.

  • A global model finds that the environmental impacts of the food system could increase by 60–90% by 2050, and that dietary changes, improvements in technologies and management, and reductions in food loss and waste will all be needed to mitigate these impacts.

  • Improving manure management can reduce nitrous oxide (N2O) emissions, but its impacts on indirect N2O emissions and other greenhouse gases need to be assessed. Structural changes that address livestock demands and spatial planning are needed.

  • One-third of human-induced reactive nitrogen emissions can be traced to livestock supply chains. Highly variable nitrogen use efficiencies along these chains uncover opportunities for more sustainable nitrogen management.
