Through participation, consumers tended to increase their consumption of fruit and vegetables, and improve their cooking skills and knowledge about food. The research also found some evidence of a ‘graduation effect’, whereby involvement in an alternative food scheme encouraged consumers to change their consumption behaviours in relation to other goods, such as household products and clothes.
Although the majority of consumers use alternative food sources alongside supermarkets, they often did not trust them and felt that the quality of supermarket food was inferior. Many reported that they only shopped there out of necessity. Alternative food projects also challenge supermarket-led notions of food choice. Although they may provide less choice in terms of types of product, consumers in our research associated these projects with a greater variety of foods, many of which are unavailable on supermarket shelves.
People take part in alternative food networks for a range of economic, ethical and personal reasons and these vary over time and in relation to life events such as moving house or the birth of a baby. For many, a key motivation was a desire to care for people and places, both close and distant. This involved reducing food miles, sourcing Fairtrade whenever possible, or looking for products with reduced environmental impacts and high animal welfare standards.
Dr Moya Kneafsey from Coventry University, who led the research commented “Consumers enjoyed being able to ask the producers about their products and felt reassured about the quality and safety of the food. Alternative food schemes enable consumers to make a direct connection with food producers, and can result in relationships of trust and loyalty.”
The researchers also identified challenges for alternative food networks. There were concerns amongst producers as to how to maintain their connection with consumers in the face of possible future growth. Many alternative food projects do not necessarily want to get bigger, as they might lose the sense of ‘connection’ which has been established between producers and consumers.
On the other hand, small schemes are under threat from two directions. First, large retailers are trying to create a sense of ‘connection’ with producers through the use of marketing strategies – such as providing names and pictures of growers and farmers on packaging. Second, rapidly expanding semi-national box delivery schemes such as Abel & Cole and Riverford Organics are also tapping into the interest in sourcing organic foods.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
