Effective interfaces of knowledge and policy are critical for food system transformation. Here, an expert group assembled to explore research needs towards a safe and just food system put forward principles to guide relations between society, science, knowledge, policy and politics.

An analysis of historical Escherichia coli samples from livestock reveals how antimicrobial resistance can spread — and how understanding the biology underlying its spread can inform effective policy actions.

Steep-slope agricultural areas are more vulnerable to future climate impacts than average global agricultural lands. Based on a new high-resolution steep-slope agricultural landscape map, this study estimates the distribution of global steep-slope agricultural landscapes in the present-day (1980–2016) and future (2071–2100) scenarios across the five major climate classes.

Genomic analyses reveal Escherichia coli samples from livestock in China have a third more plasmids than 50 years ago, contributing to the spread of antimicrobial resistance.

Greenhouses and vertical farming enable food production in cities, but their energy and energy-related land demands may affect their overall sustainability in specific regions. Through geospatial and mathematical modelling, this study compares open-field and two indoor farming methods for vegetable production in nine city-regions around the world.

Modelling analysis shows that the current rates of annual rice yields of the Southeast Asia region will not be able to produce a large rice surplus in the future unless the exploitable yield gap is narrowed down substantially within the next 20 years.

The reduction of food loss and waste is urgent, yet strict food waste regulations can be costly and unpopular. Drawing on a large set of survey experiments conducted in a high-income country, this study assesses the positive impact that specific policy framing, design and feedback may have on citizens’ level of support to these regulations.
