Different foods will have different consequences for greenhouse gas emissions, other environmental impacts and for health. This category contains links to research which analyses particular food groups including meat, fruit and vegetables, carbohydrates and dairy products.
FCRN mailing list member Kurt Schmidinger has recently been awarded his thesis on the following subject: "Worldwide Alternatives to Animal Derived Foods – Overview and Evaluation Models", subtitle "Solutions to Global Problems caused by Livestock".
FCRN mailing list member Anna Flysjö has successfully defended her thesis. The thesis takes the form of a summary overview section and 6 papers (5 of them published journal papers). Details as follows:
The PhD project has focused on some of the most critical methodological aspects influencing GHG emission estimates of milk and dairy products and how the methodology can be improved. In addition, the CF for different types of dairy products has been analysed. Based on these results, mitigation options have been identified along the entire dairy value chain.
The findings of this study are unlikely to surprise anyone – the research is based on experiments carried out in the US and the UK and finds that there is a strong connection in people’s minds between eating meat—especially muscle meat, like steak—and masculinity.
The cross-research council Food Security website reports on the findings of a team from the University of Cambridge and Rothamsted Research. This team has identified a family of genes that could help us breed grasses with improved properties for diet and bioenergy.
This paper fish demand in 2050 will be met but only if fish resources are managed sustainably and the animal feeds industry reduces its reliance on wild fish.
This paper finds that in 2007–2008, oil palm plantations directly caused 27% of total and 40% of peatland deforestation. Under a business as usual (BAU) scenario, by 2020 ∼40% of regional and 35% of community lands will be cleared for oil palm, generating 26% of net carbon emissions.
The Scottish Aquaculture Research Forum has published a study on Scottish produced suspended mussels and intertidal oysters.
The study considered the cradle-to-gate impacts of the shellfish, from spat collection in the case of mussels, and hatching in the case of oysters, through growing, harvesting, depuration, and packing ready for dispatch. To illustrate the carbon impacts of the full life cycle, a scenario is included that, based on various assumptions, illustrates the potential impacts of distribution, retail, consumption and disposal of the shells.
The UK dairy sector has published its first report which looks at the carbon footprints of a selection of British dairy farms with a view to establishing a baseline against which progress can be measured. The study reveals very substantial differences in the GHG footprints expressed as CO2 eq/kg fat corrected milk, of different farms, and also finds that there is more variation between farms, than between production systems. It also concludes that there is no one variable (eg milk yield, fertiliser use or energy consumption) that accounts for most of the variation between farms.
This study, commissioned by the Australian Egg Corporation, investigates the egg industry’s impacts in terms of greenhouse gas emissions, energy and water use. It looks at both caged and free range egg production.
France’s Constitutional Council has approved a tax on sugary drinks. The tax, which works out to one euro cent per can of drink, is expected to bring in 120 million euros ($156 million) in state revenues.
John Forster, an FCRN mailing list member, has written two very interesting articles on aquaculture for the UK Research Councils’ Food Security website www.foodsecurity.ac.uk
In June 2011, Arla Foods launched its Global Environmental Strategy 2020, which maps the entire environmental impact of its dairy products and includes a pledge to reduce global CO2 emissions by 25% by 2020 within the areas of production, haulage and packaging.
This should get you out into the garden. If you don’t want to get your hands dirty, you can buy a half dozen chocolate coated ants or worms at Fortnum and Mason’s for a mere £7.
This paper is by some of the same authors who wrote a paper for Friend of the Earth (see mailing of 23/10/10) which modelled the health impact of a lower meat diet. You can read the FoE report here.
The FOE report essentially argues that a lower meat diet would deliver major health improvements largely because it assumes that a reduction in meat intakes will be compensated for by an increase in fruit and vegetables – which of course may or may not be the case.
This paper considers what we know about the contribution that the fruit and vegetable sector makes to the UK's greenhouse gas emissions. It also looks at what we know about the options for achieving emissions reductions.
