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.

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.

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.

Consumers’ interest in local food has recently increased, even if the distinction between local and global food still remains unclear. Aside from the concept of food-miles, no metrics exist to quantify the level of “localness” of a product. In this study, five criteria for making this distinction are derived from the literature: geographical distance, supply chain size, supply chain length, identity, and governance. Two case studies from the Swiss cheese sector are analyzed using these criteria in order to illustrate the application of the framework and to show the differences in their localness. On average, the local cheese obtains a degree of localness of 56% and the global one achieves 31%. There are small differences in “geographical distance” and “supply chain length”; but the distinction lies more in “supply chain size,” “identity,” and “governance.” This study shows that these cheeses hide a local–global hybridity, by promoting local attributes and values while being embedded in international markets.

The circular economy (CE) has shown promise for achieving several of the UN’s Sustainable Development Goals, replacing the linear system and reducing negative impacts on the environment. This research aims to assess the effective adoption of CE principles in three cheeses with geographical indication (GI) through an analysis of the practices identified in their respective value chains. Qualitative interviews show the persistence of historical practices that preserve the heritage behind the product, maintain autonomy in relation to external inputs and save energy or make intelligent use of by-products. Radical adoption of CE principles requires innovation to reduce the use of new inputs and greenhouse gas emissions. GI food products are generally not constrained by standards beyond those set by law, but their specifications can be modified, while respecting practices consistent with the link to the terroir. However, the remoteness of small businesses in deep rural areas, far from research centers, is slowing down the transfer of knowledge and the adoption of the latest technologies, particularly in mountainous areas. More participatory research and innovative initiatives are needed to ensure the transition to a circular economy for traditional mountain products, which are strongly linked to local culinary traditions and cultural identity.
