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.
FCRN member Charlotte Kildal has co-authored this paper documenting the Norwegian Armed Forces’ attempt to introduce the Meatless Monday campaign, where only vegetarian meals are served on one day each week. The paper found that the initiative had mixed results.
College students who take a course on food and the environment reduce their reported ruminant meat consumption by 28% relative to their consumption prior to the course, according to this paper by FCRN member Jennifer Jay of UCLA Civil and Environmental Engineering.
According to this randomised controlled trial, people eat an average of 500 kcal more per day when offered ultra-processed food compared to unprocessed food (as defined by the NOVA system). Furthermore, the trial subjects gained weight on the ultra-processed diet and lost weight on the unprocessed diet.
According to this paper, survey participants were less likely to support implementing carbon taxes if they were also given the option of implementing a “green nudge” policy (making renewable energy plans the default option for residential consumers, but not compulsory).
This modelling paper finds that strategies to mitigate climate change could put an additional 160 million people at risk of hunger by 2050, if they are not designed carefully. However, these trade-offs could be avoided at a cost of around 0.2% of GDP in 2050.
This paper, produced by the Centre for the Study of Existential Risk at the University of Cambridge, outlines a system that could produce animal feed with lower environmental impacts than conventional soybean production. The system combines LED lighting, indoor photobioreactors, atmospheric carbon capture and geothermal energy to produce an algae-based feed product.
This paper explores industrial influence over industry-funded studies, using Coca-Cola as an example. It finds that, despite Coca-Cola developing a set of principles to guide transparency in the research it funds, the terms of funding it provides for some projects theoretically allow Coca-Cola to terminate studies early without reason and demand the recall of all documents from the study. However, no evidence was found of Coca-Cola having actually suppressed the publication of studies with unfavourable results.
Extreme climate events such as droughts and heat waves are better predictors of yield anomalies than indicators of climate averages in maize, rice and soybeans, according to this paper. Irrigation can mitigate the negative yield impacts of frequent warm days.
This paper, written by researchers on the University of Oxford’s LEAP project and co-authored by the FCRN’s Tara Garnett, explores what drives the intensification of dairy farming, and the consequences for the environment, animal welfare, socio-economic wellbeing and human health. The paper also considers three potential approaches to addressing these consequences: sustainable intensification, multifunctionality, and agroecology.
This paper calculates the environmental impacts (climate change, acidification, eutrophication, land use, and water use) caused by either making a meal by using a meal kit (which contains pre-portioned ingredients for cooking a meal) or by buying the ingredients from a grocery store.
One in five adults in England, Wales, and Northern Ireland experienced some level of food insecurity in 2016, according to this paper, with people who are younger, non-white, less educated, disabled, unemployed or low-income being more likely to experience food insecurity. Low-income adults had a 28% probability of being food-insecure in 2004, which by 2016 had risen to 46%.
The impacts of palm oil plantations on human wellbeing depend on context and are neither uniformly negative nor positive, finds this study of villages in Indonesia. Oil palm plantations are more likely to lead to improved basic, physical and financial well-being in villages with relatively low existing forest cover and where most people make a living by producing goods for market, compared to villages with higher forest cover and where most people have subsistence-based livelihoods.
This paper maps the potential for different subnational, national, or regional areas to reduce their agricultural dependence on imported phosphorus fertiliser by recycling manure or urban waste (including both human excreta and household and industrial wastes).
This paper reviews data from the UK Biobank study and finds that higher consumption of red meat and alcohol are associated with a higher risk of colorectal (bowel) cancer, while higher consumption of fibre from bread or breakfast cereals is associated with a lower risk.
