This opinion article suggests that microbial biomass from bacteria, yeasts, or fungi could be used as human food and animal feed, with the advantage of using less land compared to conventional crop production, particularly if feedstocks were derived directly from atmospheric carbon dioxide.

This paper finds that production of the top ten global crops has already been affected by climate change, with mixed impacts across both crop type and geographical area. Oil palm has seen a 13% decrease in yields relative to those that would have been seen under historical climate conditions, while soybean has seen a 4% increase.

This paper by FCRN member Elinor Hallström assesses the nutritional content and climate impact of 37 seafood products. The paper finds high variability in nutritional and climate performance, with no consistent correlation between nutrition and climate impact across different seafood species. The paper calls for dietary advice to promote species with low climate impact and high nutritional value, including sprat, herring, mackerel and perch.

A jury-style event hosted by the UK’s Food Ethics Council finds that a meat tax is too simplistic. The event saw four “expert witnesses” give evidence on the impacts of meat and sugar taxes, the environmental impacts of grazing livestock, and the health impacts of consuming processed and ultra-processed meat.

In this research note, the US-based Open Philanthropy Project discusses whether animal welfare might be helped or hindered by climate-focused reductions in meat consumption. For example, the note points out that meat types with a relatively low carbon footprint (e.g. chicken) are often from smaller animals (compared to, say, cows) and thus require more animals to be farmed and killed.

Organic charity the Soil Association is calling for the UK government to introduce a mandatory meat-free day each week for school catering to tackle climate change and increase fibre intake, noting that few schools currently follow the voluntary plant-based day recommended by the current School Food Standards.

This open access book, by Anna Davies, uses case studies to examine the past and present of food sharing in cities.

The US-based Good Food Institute, which promotes plant-based foods and lab-cultured meat, has produced two State of the Industry Reports on plant-based and cell-based foods. The report outline industry developments during 2018, list the main industry actors, discuss regulatory updates in the United States, and analyse investment trends.

This report from the Eating Better Alliance surveys 620 sandwiches available from retailers in the UK. It finds that 85% of sandwiches on the market still have meat, fish or cheese as their main ingredient, and only two sandwiches had any “better meat” certification (RSPCA Assured logos).
