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.
If you only read one report highlighted in this section – read this. It’s a study commissioned by the Committee on Climate Change as supporting research for the publication of its latest Annual Report and is a really fascinating piece of work.
An interesting article demonstrating the rebound effect resulting from increasing energy efficiency in the road freight transport sector in Portugal. Matos F J F and Silva F J F (2011). Energy Policy. The rebound effect on road freight transport: Evidence from Portugal, 39, 5, 2833-2841
The Deparment for Transport has published its 2010 report which reveals a declining level of concern for the environment and and the usual complex tangle of human inconsistencies and hypocrisies.
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.
WWF has released its Livewell report, that looks at whether it is possible to eat a diet that is both lower in GHG emissions and more nutritionally balanced than current dietary norms in the UK.
This workshop was organised by the Food Climate Research Network and supported by Defra and the Committee on Climate Change on 21 January 2010. The workshop participants explored the role that soil carbon sequestration approaches can play in reducing agricultural emissions, the potential downsides and trade offs with other environmental concerns, and the gaps in our knowledge that need to be filled.
This paper summarises the presentations and discussions that took place at a workshop organised by the Food Climate Research Network on 21 January 2010.
This paper reports on an in-depth study of refrigeration in the UK food chain. It identifies the greenhouse gas impacts of the ‘cold chain’ and discusses some of the technological options for reducing these.
The Committee on Climate Change has published its second progress report to Parliament. It says that a step change in the pace of underlying emissions reductions is still required if the UK is to meet its legislated carbon budgets - which require at least a 34% cut in emissions by 2020 relative to 1990 levels. Emissions of greenhouse gases have declined over the past year (by 8.6%), but this is almost entirely due to a reduction in economic activity caused by the recession and increased fossil fuel/ energy prices, and is not the result of the implementation of measures to reduce emissions.
Pelletier N, Pirog R, Rasmussen R (2010). "Comparative life cycle environmental impacts of three beef production strategies in the Upper Midwestern United States", Agricultural Systems 103 (2010) 380–389 This paper compares three US beef rearing systems. Cattle are finished either in: feedlot systems (having received hormone implants); backgrounding systems (also with hormone implants); or on pasture (no implants).
In November 2009 Japan's Ministry of the Environment released an Annual Report on the Environment, the Sound Material-Cycle Society and the Biodiversity in Japan 2009, Abridged and Illustrated for Easy Understanding.
Premier Foods (manufacturers of brands such as Hovis, Sharwoods, Mr Kipling, Quorn, Ambrosia, Angel Delight, Bisto, Cadbury, etc) is moving forward its target on 100% sourcing of sustainable palm oil. The original target (made in 2008) was to source all its palm oil from sustainable sources by 2011. The target has now been moved forward to the end of 2010.
In November 2009 the World Watch Institute released a report arguing that the FAO's estimate of livestock's total contribution to global GHG emissions (18%) is a serious underestimate and that the true footprint of livestock production is around 51% higher.
A study published in September 2008 finds that organic agriculture in Africa can be equal or better for food security than most conventional systems and is more likely to be sustainable in the longer term, as it builds up levels of natural, human, social, financial and physical capital in farming communities. It also favours the use of low carbon footprint production methods and local resources.
The Food Standards Agency has published a systematic review which it commissioned which sought to determine the size and relevance to health of any differences in content of nutrients and other substances in organically and conventionally produced crops and livestock products. The focus of the review was the nutritional content of foodstuffs.
This paper argues that organic agriculture can feed the world. The authors state that the principal objections to the proposition that organic agriculture can contribute significantly to the global food supply are low yields and insufficient quantities of organically acceptable fertilizers. They evaluate the universality of both claims.
