FCRN member Ujué Fresán has co-authored this paper, which calculates the environmental impacts associated with the packaging of several breakfast foods (including orange juice, cereals and peanut butter). For each food product, significant differences in carbon footprint were found, depending on packaging size, packaging materials and brand. Packaging consistently accounted for a lower carbon footprint than production of the food item itself.

This paper argues that animal product alternatives (including both plant-based products and cellular agriculture) are likely to be implemented within the current “corporate food regime” and may not be compatible with a food sovereignty perspective. However, it suggests that using a “food tech justice” lens could guide animal product alternatives towards a role in a food system that considers health, equity and sustainability.

This paper, co-authored by FCRN member Alexandra Sexton (who is part of Oxford’s Livestock, Environment and People project), identifies key moments in the field of cellular agriculture from the past two decades. The first wave of largely university-based research lasted until the 2013 presentation of the cultured burger created at Maastricht University, while the second wave has seen the emergence of a start-up culture.

This paper maps the potential for restoring forests across the world, finding that there is room for a 25% increase in forested area without interfering with existing forests or urban and cropland areas. This could store 205 Gt of carbon after several decades (for comparison, current emissions from fossil fuels and cement production are roughly 10 Gt of carbon each year).

This narrative review paper explores how understanding of nutrition and public health have changed over time, influenced by developments in science, social changes and policy-making. The paper identifies some major paradigm shifts, such as the identification of vitamins in the early 20th century, and the recognition of the link between dietary patterns and some chronic diseases in the late 20th century.

This paper describes four scenarios that reflect ways in which the food system might change in the near future, based on two main factors: dietary shifts and degree of globalisation. The paper suggests that such scenario analyses can be helpful in envisaging future paths beyond “business as usual”, even when the future of the food system is non-linear and hard to predict.

Fisheries often discard large quantities of unwanted catches at sea, but policies are being brought in to limit such discards. According to this paper, Northern gannets (seabirds) rely more on fishery discards in years when there are shortages in their natural prey (mainly mackerel) - shortages that may be due to pressure from fisheries. The paper argues that fishery discards are not an adequate substitute for natural prey.

This book chapter questions the validity of viewing food primarily as a tradable commodity, noting that doing so encouraging policies based on markets, corporate profit and the private enclosure of resources that were previously freely available to all. The authors propose, instead, that food should be viewed as a commons, i.e. a shared resource.

This systematic review of taxes on sugar-sweetened beverages (SSBs) finds that the taxes are associated with a decrease in the amount of sugar-sweetened beverages that are bought and consumed. A 10% tax lead to a 10% decrease in purchase and intake levels, on average, although there was considerable variation between results in different locations.

This paper presents a newly developed open-source system for precision agriculture in lettuce production. The system, known as AirSurf, uses a lightweight manned aircraft to gather images of lettuce fields, then a deep learning algorithm assesses the state of the lettuce crops on a number of characteristics, including lettuce size and number per field.

This paper analysed thousands of items of children’s clothing and found that many feature images of food - particularly on girls’ clothing - and that those images often depict unhealthy food types.

According to this paper, households in the Netherlands wasted 41kg of solid food per person in 2016 - a 15% decline since 2010. Furthermore, 57 litres per person of potable liquids such as coffee, tea and milk are disposed of via the sink or toilet each year. Rice, bread, pasta, vegetables and pastries are among the food types most likely to be wasted (as a percentage of purchased quantity).

This paper sets out a new method to account for nutrition in the functional unit of life cycle assessments of single foods. The method accounts for the wider dietary context of each food type, which is found to affect the results relative to using either mass as a functional unit, or another nutrient-based functional unit that does not consider the dietary context.

This perspective piece argues that the definition of protein quality should be updated to reflect both environmental and nutritional concerns.

According to this study of farmland birds in Finland, bird abundance is positively correlated with the nearby presence of organic animal farms, as well as the percentage of nearby field cover and the presence of natural grasslands.

Methane emissions from ammonia fertiliser manufacturing plants (which use natural gas as a feedstock and energy source) in the United States are around one hundred times higher than currently reported levels, according to this study. Researchers used a Google Street View car equipped with methane analysers to take measurements downwind of six ammonia fertiliser plants (there are only 23 such plants in the US).
