The European Commission has set out a European Green Deal, a plan to transform the European economy to net-zero emissions by 2050, and to decouple economic growth from resource use. The Green Deal will include a new “Farm to Fork” strategy (to be set out in full in the spring of 2020) to reward food producers for services such as storing carbon in the soil, improving water quality and reducing the use of pesticides, fertilisers and antibiotics.

This report by the European Alliance to Save Our Antibiotics assesses the antibiotics policies of ten leading British supermarkets. It finds that six out of the ten supermarkets ban their suppliers from routinely using antibiotics, with Waitrose having the most comprehensive antibiotic policies.

This paper quantifies the economic impact of herbicide resistance developed by the weed Alopecurus myosuroides (black-grass). It finds that the annual cost of this resistance is £0.4 billion each year in England, based on lost profit from lower crop yields. The global cost of herbicide resistance could be much higher, as there are 253 known herbicide-resistant weeds.

This paper argues that international measures to protect marine biodiversity should include protected areas that can move over space and time to adapt to the changing ranges of certain species, whether because the species in question are migratory, or because their ranges are changing because of climate change.

This paper used satellites to observe the effect on yield of conservation tillage practices, such as reducing soil disturbance and leaving crop residues in the field, in the United States Corn Belt. The researchers found that long-term conservation tillage (i.e. from 2008 to 2017) was associated with a 3.3% increase in maize yields and a 0.74% yield increase for soybeans.

This Guardian article discusses farms that are growing crops organically without using animal manure or blood and bone meal, in contrast to most organic farms. This approach is not yet widespread, with only around 50 such farms in the United States. Relevant organisations include the Biocyclic Vegan Standard and the Vegan Organic Network.

This report from the Food Systems Group of Oxford’s Environmental Change Institute argues that small-scale (less than 20 ha) family farms are and will continue to be important suppliers of food in middle- and low-income countries, and that oversimplified narratives get in the way of effective policymaking.

This progress report to the Scottish Parliament from the UK’s Committee on Climate Change shows that, while Scotland’s overall greenhouse gas emissions fell by 3% in 2017, the Scottish Parliament's 2030 target to reduce emissions by 75% will be extremely challenging to meet.

In this report, the global non-profit World Resources Institute lists 23 ways in which the food service sector could encourage diners to choose dishes that contain more plants and less ruminant meat.

According to this paper, most meat-eaters think that vegetarian and vegan diets are ethical, good for the environment, healthy and socially acceptable, but also tend to believe that these diets are difficult, not tasty, inconvenient and expensive. Vegetarian diets tend to be viewed more positively than vegan diets across all measures included in the survey, except for ethical considerations and the environment, where vegan and vegetarian diets are viewed equally.

This report from FoodPrint, part of the GRACE Communications Foundation, describes the problems associated with plastic, metal and paper/fibre food packaging. It also sets out potential solutions, including reusable food containers, plastics that can be more easily recycled, compostable packaging materials, and bans on certain types of packaging (e.g. plastic straws).

In this report, the UK’s Sustain alliance describes progress made by six London boroughs in developing Good Food Retail projects (supported by Sustain). Projects included helping convenience stores to offer a greater range of healthy foods, and improving public awareness of and uptake of Healthy Start vouchers.

This review paper argues that obesity and mortality in the United States could be reduced by limiting consumption of sugar-sweetened drinks and processed foods and meats, because of the tendency of processed foods to encourage people to eat more food (based on trials in people), and the inflammatory effect of emulsifiers such as carboxymethylcellulose and polysorbate-80 (based on mouse and in vitro studies, not studies in people).
