The EAT-Lancet Commission sets out a “universal healthy reference diet” that it argues will allow the food system to remain within the planetary boundaries while feeding 10 billion people by 2050. The suggested diet includes a variety of plant-based foods and low amounts of animal-based foods.
Insects, seaweed, microalgae, cultured meat, mycoprotein and mussels are among the nine ‘future foods’ discussed in this paper, co-authored by FCRN member Hanna Tuomisto, which compares the nutritional profiles and environmental impacts of these foods with conventional plant- and animal-sourced foods.
A hard Brexit, where the UK trades with other nations on the terms and tariffs set out by the World Trade Organisation after leaving the European Union, could cause an additional 5,600 deaths in the UK, mainly due to reduced consumption of fruits, vegetables and nuts, according to a working paper published by the Oxford Martin School.
The global agricultural system doesn’t produce enough fruit, vegetables and protein to meet the nutritional needs of the world’s population, according to this paper. Meanwhile, grains, fats and sugars are overproduced, relative to what is needed for a healthy diet (defined in this paper as a diet in accordance with the Harvard Healthy Eating Plate (HHEP)).
The Food and Agriculture Organisation of the United Nations has released the September 2018 version of its quarterly reports, “Crop prospects and food situation”. According to the report, 39 countries currently require external food assistance, driven by conflicts and climate-related shocks. Of those countries, 31 are in Africa, seven are in Asia, and the remaining one is Haiti. World cereal production in 2018 is estimated to be 2.4% lower than in 2017, which saw a record high.
Utilities company Veolia and plastics charity RECOUP have together released the report “Plan for plastics”, which considers how the UK can improve plastic recycling. The report finds that 93% of people think plastic bottles should be made with recycled materials and are willing to pay 2.5 pence more, on average, for a recycled bottle (compared to a non-recycled bottle). Less than 5% of plastic film is currently recycled, compared to 59% of plastic bottles.
Alcohol production, packaging and transport in Sweden has a carbon footprint of 52 kg CO2 eq. per person and accounts for around 3% of dietary emissions, according to a new paper by FCRN member Elinor Hallström. Per litre of beverage, wine, strong wine and liquor have higher carbon footprints than beer. This study does not include emissions from retail or consumer activities.
A new paper in Science reviews trends in meat consumption and the associated health and environmental implications. The paper also discusses potential means of influencing meat consumption levels.
A new report from the Institute for Agriculture and Trade Policy (IATP, a US non-profit research and advocacy organisation) and Genetic Resources Action International (GRAIN, a non-profit headquartered in Spain) finds that the five largest meat and dairy companies together account for more greenhouse gas emissions than ExxonMobil, Shell or BP. The top 20 meat and dairy companies have greater emissions than some nations, including the UK and Australia. The report argues that by 2050, the meat and dairy industry could account for 80% of the planet’s greenhouse gas budget if the industry grows as projected.
The UK’s Eating Better alliance has published a survey of ready meals in the main UK supermarkets. The briefing reports that only 3% of the 1350 ready meals surveyed were entirely plant-based; vegetarian, plant-based and meat substitute meals altogether made up 14% of the meals surveyed; 77% of the meals contained meat; and 10% contained fish or seafood. Some retailers sell vegan and vegetarian ready meals at a higher price than other meals, most notably Tesco’s Wicked Kitchen vegan range, which is 67% more expensive than Tesco’s regular range. Nearly one third of meat-based meals did not specify the country of origin of the meat, while only three retailers included the meat in their own-brand ready meals under their farm animal welfare policies.
Smallholders with farms under two hectares produce 28–31% of all crops and 30–34% of all food supply on 24% of the world’s agricultural land, according to a new paper. This contrasts with common claims that smallholders produce 70–80% of the world’s food. The paper also finds that, relative to larger farms, farms under two hectares have greater crop species diversity, allocate less of their crop outputs towards feed and processing and are important suppliers of fruit, pulses, roots and tubers.
FCRN member Dr Rosemary Green of the London School of Hygiene & Tropical Medicine has published a paper that calculates the greenhouse gas (GHG) emissions and water use associated with five dietary patterns in India. As shown below, GHG emissions per capita are highest for the “rice and meat” dietary pattern (at 1.2 tonnes CO2 eq. per year) and lowest for the “wheat, rice and oils” pattern (at 0.8 tonnes CO2 eq. per year). For comparison, per capita dietary GHG emissions in the UK have been estimated at 2.6 tonnes CO2 eq. per year for high meat eaters and 1.1 tonnes CO2 eq. per year for vegans (Scarborough et al., 2014). Water use is highest for the “wheat, rice and oils” pattern and lowest for the “rice and low diversity” pattern.
FCRN member Martin Heller of the Centre for Sustainable Systems at the University of Michigan has calculated the greenhouse gas emissions (GHGEs) and energy demand associated with the diets of individuals in the US, based on a one day dietary recall survey. The highest-emitting 20% of diets are responsible for 46% of diet-related GHGEs, while the lowest-emitting 20% of diets cause 6% of diet-related GHGEs. The food types causing the highest percentage of GHGEs are meats (57%), dairy (18%), beverages (6%) and fish and seafood (6%).
This paper estimates greenhouse gas emissions (GHGEs) associated with the food purchased by US households (based on survey data) and examines the links between food GHGEs and demographic factors. It suggests that education on the links between food and climate could be targeted at more educated and more affluent consumers, since their research shows (see below) that the these households have more GHGE-intensive dietary patterns.
A new study published in Science has consolidated data on five environmental impact categories (land use, freshwater withdrawals weighted by local water scarcity, climate change, acidification and eutrophication) for 40 agricultural goods from over 38,000 farms. It finds that the environmental impacts of producing the same food are highly variable between different farms. It also finds that the environmental impacts of animal products are generally higher than plant-based products.
This book, by Ludovica Principato, reviews information on consumer-level food waste, including the factors and behaviours affecting food waste levels, policies and initiatives.
