This paper summarizes the main findings of the GLAMUR project which starts with an apparently simple question: is "local" more sustainable than "global"? Sustainability assessment is framed within a post-normal science perspective, advocating the integration of public deliberation and scientific research. The assessment spans 39 local, intermediate and global supply chain case studies across different commodities and countries. Assessment criteria cover environmental, economic, social, health and ethical sustainability dimensions. A closer view of the food system demonstrates a highly dynamic local-global continuum where actors, while adapting to a changing environment, establish multiple relations and animate several chain configurations. The evidence suggests caution when comparing "local" and "global" chains, especially when using the outcomes of the comparison in decision-making. Supply chains are analytical constructs that necessarily-and arbitrarily-are confined by system boundaries, isolating a set of elements from an interconnected whole. Even consolidated approaches, such as Life Cycle Assessment (LCA), assess only a part of sustainability attributes, and the interpretation may be controversial. Many sustainability attributes are not yet measurable and "hard" methodologies need to be complemented by "soft" methodologies which are at least able to identify critical issues and trade-offs. Aware of these limitations, our research shows that comparing local and global chains, with the necessary caution, can help overcome a priori positions that so far have characterized the debate between "localists" and "globalists". At firm level, comparison between "local" and "global" chains could be useful to identify best practices, benchmarks, critical points, and errors to avoid. As sustainability is not a status to achieve, but a never-ending process, comparison and deliberation can be the basis of a "reflexive governance" of food chains.

In the debate surrounding the sustainable future of food, claims like “buy local” are widespread in publications and the media, supported by the discourse that buying “local food” provides ecological, health and socio-economic benefits. Recognising the lack of scientific evidence for this claim, this paper aims to compare the results of sustainability assessments for 14 local and global food products in four sectors within four European countries. Each sector has been analysed independently using sustainability indicators across five dimensions of sustainability: environmental, economic, social, health and ethics. In order to determine if local products generally perform better, an outranking analysis was conducted to rank the products relative to their sustainability performance. Outranking is a multi-criteria decision aid method that allows comparison of alternatives based on quantitative and qualitative indicators at different scales. Each product is also characterized by a degree of localness in order to relate sustainability and localness. The results are given in the form of phi flows, which are relative preference scores of one product compared to other ones in the same sector. The rankings showed that global products consistently come last in terms of sustainability, even when the preference functions and weighting of the indicators were varied. The first positions of the rankings were taken either by the most local or an intermediary product. Moreover, detailed rankings at the attribute level showed the relative strengths and weaknesses of each food product along the local-global continuum. It appeared that the strength of local and intermediary products was mainly in health and socio-economic dimensions, particularly aspects of care and links to the territory such as biodiversity, animal welfare, governance or resilience. In relation to global food products, they presented substantial advantages in terms of climate change mitigation and affordability to consumers. This contrasts with the food-miles ecological claim. Thus, we conclude that distance is not the most critical factor in improving sustainability of food products, and that other criteria of localness (identity, governance or size) play a more critical role. © 201

Abstract:Local food has recently gained popularity under the assumption that it is more sustainable than food from distant locations. However, evidence is still lacking to fully support this assumption. The goal of this study is to compare local and global food chains in five dimensions of sustainability (environmental, economic, social, ethical and health), covering all stages of the chain. In particular, four cheese supply chains are compared in detail: a local (L'Etivaz) and global (Le Gruyère) case in Switzerland and a local (Single Gloucester) and global (Cheddar) case in the UK. A multi-dimensional perspective is adopted to compare their sustainability performance. Eight attributes of performance (affordability, creation and distribution of added value, information and communication, consumer behaviour, resource use, biodiversity, nutrition and animal welfare) are used to frame the comparative analysis. The results suggest that local cheese performs better in the field of added value creation and distribution, animal welfare and biodiversity. Global chains, by contrast, perform better in terms of affordability and efficiency and some environmental indicators. This analysis needed to be expressed in qualitative terms rather than quantified indicators and it has been especially useful to identify the critical issues and trade-offs that hinder sustainability at different scales. Cheese supply chains in Switzerland and the UK also often present hybrid arrangements in term of local and global scales. Comparison is therefore most meaningful when presented on a local (farmhouse)/global (creamery) continuum.

Abstract:The protection of geographical indications (European regulation 1151/2012) is arguably the most significant initiative, certainly within Europe, that promotes foods with territorial associations and reorganises agri-food chain governance through a strategy of reterritorialisation. Research on Protected Designation of Origins (PDOs) and Protected Geographical Indications (PGIs) suggests that they generate significant economic value at an EU-level, especially in certain countries. They can also help to deliver territorial rural development policy and develop new food markets. In this paper we examine the way the PDO scheme has been developed and applied in one commodity sector (cheese) in two countries (Switzerland and the UK), where the uptake of PDOs is variable. We adopt a food chain approach and examine specific cheese product case studies (at micro and meso levels) in both countries to better understand how the PDO scheme (as a territorialisation and respacing strategy) is implemented. L'Etivaz and Le Gruyère are examined in Switzerland. Single Gloucester and West Country cheddar are examined in the UK. The PDO scheme is an important governance strategy and regulatory system, but despite strict guidelines regarding implementation and geographical infrastructure there are notable differences between the UK and Switzerland in terms of how the label is used to organise and respatialise food chains: it is framed as a strategy to protect the rural economy in Switzerland but is promoted more as a mechanism to communicate and reconnect with consumers in the UK.
