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.
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.
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.
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.
There is widespread engagement of the scientific community with industry. Statements of competing interest are, therefore, an important mechanism for readers to assess real and perceived biases in published research and commentary.
Trade-offs between land-based climate change mitigation efforts and food security are common to most decarbonization scenarios. Accounting for climate impacts and inclusive policy design can reverse this trend.
Chemical and pathogenic hazards in aquaculture supply chains threaten the provision of safe aquatic food. The Seafood Risk Tool is an integrated, semi-quantitative system that develops bespoke supply chain and risk management strategies.
High-resolution maps of livestock production in China indicate that dietary and production changes to lower nitrogen pollution could generate human and ecosystem benefits that outweigh the costs.
Aquaculture sector expansion requires limiting the chemical and pathogen hazards that can disrupt seafood supply. A schema is presented here for mitigating these risks and informing policy.
Emissions abatement efforts in the agriculture, forestry and land-use sector are vital to achieve climate change mitigation targets, but their effects on food security remain poorly understood. Using six global agroeconomic models, this study explores how afforestation, bioenergy and non-CO2 emissions reductions could impact agricultural prices and the risk of hunger under different scenarios.
Aquaculture must grow above the current rate of 11% per year to meet projected demand and reduce dependence on seafood imports. Government support and private investment are urgently needed for sustainable growth.
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.
Relocating livestock closer to croplands could increase opportunities for manure recycling and reduce the need for synthetic fertilizer — facilitating nitrogen pollution abatement and reducing the impacts of nitrogen pollution on human health.
