Food price data at the retail level are critical to assessing the impacts of covariate shocks on people’s access to healthy, nutritious diets. Through the calculation of cost and affordability, retail food prices can also help identify entry points to improve food and nutrition security, such as in the context of COVID-19.
Degrowth can aid climate mitigation in the food system by integrating reduced animal protein demand, emissions pricing and wealth redistribution into a global food systems transformation.
Substituting animal-source foods with novel and future foods in our daily diets is essential to mitigate global environmental change. An integrated statistical approach and optimization model support a shift to alternative, more sustainable diets.
Tillage intensity is increasing across the US corn–soybean cropping systems due to increased weed resistance. The more intensive tillage regimes are likely to have negative impacts on greenhouse gas emissions from soils.
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.
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.
Animal-derived serum use in culture media is a financial, ethical and sustainability challenge for scaling up cultured meat production. Now, an omics approach has identified key cellular signals that allow myocytes to develop in the absence of animal serum.
Feeding animals with low-opportunity-cost biomass — a principle of circular agriculture — may upgrade the role of cattle and pigs in sustainable and healthy food systems, as represented by the EAT–Lancet dietary recommendations.
