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.

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.

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.

Systems used to categorize processed foods display variation in the impact of highly processed food on risk factors for non-communicable disease. Clarity is needed on the contribution of nutrients, additives and sensory properties of foods categorized as highly processed to health and disease.

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.

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.

A self-powered electrical stimulation system that harvests wind and raindrop energy has the capacity to stimulate crop growth via the all-weather triboelectric nanogenerator. A small-scale experiment shows that the system can increase ~26.3% of the germination speed and ~17.9% of yield for peas.

The pace of dietary shifts towards the EAT–Lancet dietary guidelines varies widely across countries. By analysing the supply of 15 essential foods in 172 countries over almost six decades, this Article estimates the level of convergence of national diets with the EAT–Lancet reference diet and the impact that closing such a diet gap would have on national and global water footprints.

Spatial planning and policy could guide China’s livestock sector towards reducing human exposure to ammonia—provided that 5–10 billion animals are relocated across the region.

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.
