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 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 report from the US-based Breakthrough Institute suggests that increasing the productivity of grazing systems, particularly in lower-income countries, can help to shrink the area of land used as pasture.

This report from the UK’s Triodos Bank calls for a radical overhaul of the food system with a focus on environmental sustainability, healthy diets, and fair pay for farmers.

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 book examines the impacts that climate change is expected to have on food security and also explores the contribution to food security that could come from wild relatives of food crops.

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.

The Oxford Martin School has helped to develop NaturEtrade, an online marketplace for ecosystems services. Landowners or managers can set a price that they would accept in return for keeping their land in its present ecological condition, rather than putting it to other uses that might degrade it. Buyers who want the land to remain unchanged, e.g. a business further downstream that wants to limit flooding, can enter into a contract with the landowner or manager.

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.
