UK charity Oxfam has launched a new campaign, Behind the Barcodes, to highlight human suffering in the food supply chain. Oxfam has scored the major UK supermarkets on their human rights policies in the categories of transparency, workers, farmers and women, and is encouraging shoppers to contact supermarkets to voice their concerns.

Disruptions to supplies of food-grade CO2 in Europe are causing shortages of carbonated drinks, meat and crumpets, and could threaten animal welfare. Gasworld explains that several European CO2 plants have prolonged their periods of maintenance downtime due to low CO2 prices (read more here).

This paper examines the role that agricultural research and innovation has in changing the food systems of developing regions, including urbanisation, decline in the importance of cereals in the diet, rise in processed foods, and shift in types of grains produced. Ways in which research affects the food system include: new breeds and varieties that are suited to small farms and/or ease of processing; cheaper inputs such as irrigation, fertilisers, herbicides and tractors; and introduction of motorised transport and temperature controlled storage. The authors call for more investment in the post-farm stages of the food system, such as processing, logistics, and wholesale, because these stages add significant value to food products.

A podcast by Planet Money discusses price fixing in the US chicken industry.

The book “A handbook of food crime: Immoral and illegal practices in the food industry and what to do about them”, edited by Allison Gray and Ronald Hinch, discusses some of the problems in current food systems that lead to food crime. Topics discussed include food adulteration, forced labour in the chocolate industry, animal transportation and regulation of food waste.

A report by Friends of the Earth Europe finds that plastic food packaging is not a solution to growing levels of food waste in Europe, contrary to some claims that packaging can reduce food waste by extending the shelf life of foods. For example, using packaging to group food together in larger packs could encourage customers to buy more food than necessary. Another example is that green beans are often cut to fit into the packaging, causing losses of 30 to 40%.

The World Wide Fund for Nature (WWF) hopes to use blockchain technology to make the entire seafood supply chain traceable. Working with tech startup TraSeable, fishing company Sea Quest and blockchain company Viant, WWF is running a pilot project to trace tuna through the supply chain by tagging catches with radio-frequency identification chips and QR codes - which can be scanned by a mobile phone.

Shoppers do not notice sustainability rating logos on packaging, according to a report by QuadPackaging and Package Insight. In the study, 60 participants had their eye movements tracked while “shopping” in a retail laboratory. The products they were presented with were fictional brands with logos claiming different levels of sustainability. The logos did not represent a real sustainability standard. While 40% of the participants said that sustainability affects their purchasing decisions, the eye-tracking technology showed that 92% of the participants did not notice the sustainability logos.

Last year, members of the European Parliament voted to ban palm oil in biofuels in Europe by 2020, citing concerns over deforestation (read more about the environmental impacts of palm oil production here). The Guardian spoke to palm oil farmers in Malaysia who are worried they will lose their livelihood. Some of the farmers were given land by the government in the 1980s and do not use recently deforested land. “Our whole community here totally depends on palm oil… everybody is scared of what is going to happen to us in two years time,” said farmer Hussain Mohamed.
