This systematic review examines the impacts on environment, food security and human health of seven types of plastic used in the food system. The authors created an interactive evidence map, which can be viewed here. Most publications focused on the agricultural stage, with fewer looking at retail, household or food waste disposal. There is relatively little evidence on the impacts of food system plastics in low- and middle- income countries.

This paper finds that suddenly banning wild meat from diets and markets, for example in response to the COVID-19 pandemic, could put some countries at risk of food insecurity, require an extra 124,000km2 of land to rear livestock as a replacement, and drive an additional 267 species towards extinction.

This paper, co-authored by Table member Prof Ken Giller, investigates how herbicide use impacts casual labour patterns on farms in Central Malawi. It finds that while herbicides can be beneficial for the households using them, herbicide use can replace some casual labour. This results in many households going hungry as they cannot find work. The study is based on a survey of 275 households as well as consultation with village leaders. 

This paper, co-authored by Table member Georg Andersson, evaluates the trade-offs between greenhouse gas emissions, calorie output and biodiversity for several farm types in Sweden. It finds that while no one farm type maximises on-farm performance for all categories simultaneously, there is potential to manage the trade-offs, for example by reducing the land used for dairy farming in favour of both cropping for food production and extensive livestock grazing.

This report by the Centre for Food Policy at City, University of London summarises the qualitative research methods that are available to help understand how people interact with food environments, including interviews, community observation and photo elicitation. The report notes that there has been relatively little qualitative (compared to quantitative) research on lived experiences of food environments, and that existing qualitative research often guides commercial product development but is less often used to inform policy.

This white paper, funded by Our Land and Water (one of 11 National Science Challenges run by the New Zealand government) and the NEXT Foundation, explores what regenerative agriculture means in the context of New Zealand and identifies 17 topics where more research is required. It acknowledges the alignment between regenerative agriculture and Māori food practices and knowledge.

This synthesis report by the United Nations Environment Programme examines how climate change, biodiversity loss and pollution can be tackled as part of the framework of the Sustainable Development Goals, including by transforming food, water and energy systems.

This briefing paper from UK food waste NGO Feedback argues that supermarkets’ strong influence on the food system means they must act urgently if the UK is to significantly reduce meat and dairy consumption - and associated greenhouse gas emissions - over the next decade.
