This paper by Verma et al., with FCRN member Thom Achterbosch as co-author, estimates that consumers across the world are probably wasting over twice as much food as previously believed. The study is based on the FAOSTAT Food Balance Sheets, but goes further than the Food and Agriculture Organisation in that it factors in how consumer affluence affects food waste. It finds that once people spend more than $6.70 per day (in total, not just on food), food waste starts to rise - suggesting that consumer food waste is an issue even in lower-middle income countries, not only in wealthier countries.

This review paper examines how people are increasingly using the ocean - even previously inaccessible areas - for seafood, animal feed, nutraceuticals (such as omega-3 fatty acids), fuels and minerals, shipping, waste disposal and many other purposes. It argues that the view of the ocean as being too big to be affected by humans is now outdated, and that effective governance is required to manage the ocean’s ecological health while allowing sustainable use of its resources.

This article in the Guardian, by food writer Bee Wilson, author of The Way We Eat Now, describes the debate around so-called ultra-processed foods. Wilson describes the classification system for processed foods developed by researcher Carlos Monteiro and the research being done on the health impacts of ultra-processed foods.

This textbook uses case studies and models to present an interdisciplinary perspective on the interactions between food, energy and water.

This book explores the many factors influencing how land use decisions are made, including culture, values, ethics, trade, governance and pressure on farmland.

FCRN member ffinlo Costain has published a response to the paper Climate change: ‘no get out of jail free card’ (summarised on the FCRN website here). Costain argues that biological methane emissions - such as those from grazing livestock - can be “warming neutral” as long as they fall by 10% by 2050. Citing Oxford climate scientist Myles Allen, Costain argues that sharply cutting ruminant numbers would only deliver a warming reduction of 0.1ºC at most, which would be outweighed within a few years by continuing carbon dioxide emissions.

The University of Oxford’s Livestock, Environment and People project has published a new series of blog posts exploring controversies in the food system. The series aims to explore and clarify areas where evidence is unclear.

UK waste charity WRAP has published guidance on compostable plastic packaging, aimed at retailers and manufacturers. The guidance covers what compostable plastics are, how they might contaminate conventional plastic recycling processes, how to label them appropriately to help people dispose of them, and six applications where compostable plastic packaging is likely to be beneficial within the UK’s current waste management infrastructure.

The UK government’s Department for Environment, Food & Rural Affairs (DEFRA) has published a set of resources on “enabling a natural capital approach” (ENCA) to guide policymakers and decisionmakers.
