Showing results for: Food chain stage
The food chain describes the physical flow of goods from agriculture through processing and distribution, to retailing to eventual consumption and waste disposal. The papers and reports in this category highlight the different issues and impacts associated with each particular stage of the food chain.
The global supermarket sector's commitments to protect public health are “generally disappointing”, finds FCRN member Claire Pulker of Curtin University. However, some progress is being made address food waste, assure food safety and quality, and support selection of healthy foods.
The upcoming book In Defence of Farmers: The Future of Agriculture in the Shadow of Corporate Power, edited by Jane W. Gibson and Sara E. Alexander, uses case studies of farmers to explore the tensions between conflicting views of the role of industrial agriculture.
A new method for monitoring nutrient concentrations in pasture in real time - using a small near-infrared spectroscopy device - could allow farmers to improve productivity by adjusting livestock grazing patterns, according to this paper.
This feature in the Guardian explores the reasons for the rapid growth of the anti-plastic movement. It also describes historical lobbying campaigns that painted plastic packaging as being the responsibility of the consumer rather than manufacturers, and outlines some of the issues associated with recycling plastic (in comparison to recycling, say, glass or metals).
Chicken processing plants in the United States will be allowed to apply for a waiver to increase their processing speed from 140 to 175 birds per minute, in response to a petition from the National Chicken Council. Civil Eats reports that workers in meat processing plants are already injured five times more frequently than all other private workers, and that both animal welfare and labour welfare advocates have previously sought to block increases in processing speed.
UK supermarket Tesco and wildlife NGO WWF have set up a four-year partnership to work on reducing the environmental impacts of food. They aim to halve the environmental impact of the average UK shopping basket, according to a metric that they will develop.
UK supermarket Sainsbury’s has started selling edible insects in 250 of its stores, becoming the first UK supermarket to do so. The barbecue-flavour roasted crickets are made by Eat Grub and contain 68 grams of protein per 100 grams of dried crickets. Eat Grub founder Shami Radia told Sky News, “We're on a mission to show the West that as well as having very strong sustainability and environmental credentials, they are also seriously tasty and shouldn't be overlooked as a great snack or recipe ingredient.”
This book, edited by John Dixon et al., sets out different farming systems used across Africa and their relationships to food security.
This paper describes the susceptibility of organisms such as bacteria to biocides such as antibiotics, insecticides and herbicide as a beneficial ecosystem service, since susceptible organisms can prevent the spread of biocide resistance by outcompeting resistant organisms (that is, in biocide-free environments). This framing is distinct from many other viewpoints, which focus on the negative costs of biocide resistance.
This paper compared soil moisture and biomass growth between pasture both with and without photovoltaic solar panel arrays. While average soil moisture was similar across the fields with and without solar panels, the field with the solar panels had more variable soil moisture: directly underneath the solar panels, persistent stores of soil water were available throughout the growing season. Without solar panels, the pasture experienced water stress in the middle of summer.
In a column for the Guardian, George Monbiot writes about the potential to create food without plants, animals or soil, using instead bacteria that feed on hydrogen (generated by solar-powered electrolysis of water) and carbon dioxide from the air. Monbiot argues that this form of food production could eventually drastically reduce the amount of land needed for the global food supply chain, and suggests that the new foodstuff could be used as an ingredient in processed foods.
This paper assesses the possibility that cephalopods, such as squid, octopus and cuttlefish, could become a more important source of food in the future. In contrast to many fish population, cephalopod populations have been rising over the last few decades, possibly due to warmer ocean temperatures. The paper gives an overviews of the nutrients provided by cephalopods and the ways that they can be used as food. The authors also note that some cephalopods, including the octopus, are intelligent and possibly sentient, raising ethical issues over their use as food.
Growing millet next to a woody shrub native to West Africa could increase biomass by over 900% compared to growing millet alone, according to this paper. The shrub, Guiera senegalensis J.F. Gmel, has tap roots that can reach water deep in the soil. The study traced the movement of water from the shrub’s deep roots to the millet stems in a simulated drought.
In a paper by FCRN member Johan Karlsson of the Swedish University of Agricultural Sciences, researchers worked together with NGOs to iteratively develop a vision for the future of food production in the Nordic countries. The final vision is based on organic farming and lower meat consumption with livestock fed only on pasture and by-products from food production.
In this piece for The Conversation, researcher Elise Wach discusses the consolidation of farmland in the UK and rising farmland prices. According to Wach, there were nine times more small farms in England 15 years ago than there are today, and the number of high-intensity large farms is rising swiftly.
This book, by David Lindenmayer, Damian Michael, Mason Crane, Daniel Florance and Emma Burns, describes best practice approaches for restoring Australian farm woodlands for birds, mammals and reptiles.
Sustainable Manufacturing and Recycling Technologies (SMART), a research and development centre at Loughborough University, has produced a post-event report of its expert panel discussion on reducing the impact of food waste held on 12 October 2018. The topics discussed include the influence of multibuy offers on food waste, the links between single-use packaging and food waste, the impacts of “wonky veg” ranges in supermarkets, and smart fridges.
13% of the UK population is now vegetarian or vegan, while a further 21% identify as “flexitarian”, according to the 2018-19 edition of the Food and Drink Report by supermarket chain Waitrose & Partners. Among other food trends, the report also discusses plastic packaging, claiming that 88% of survey participants who had watched the final episode of the wildlife documentary Blue Planet II have changed how they use plastic.
