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.

This paper investigates firms' optimal location choices explicitly accounting for the role of inwards and outwards knowledge spillovers in a dynamic Cournot oligopoly with firms that are heterogeneous in their ability to carry out cost-reducing R&D. Firms can either locate in an industrial cluster or in isolation. Technological spillovers are exchanged between the firms in the cluster. It is shown that a technological leader has an incentive to locate in isolation only if her advantage exceeds a certain threshold, which is increasing in firms' discount rate, in industry dispersion, and in the intensity of knowledge spillovers. Scenarios are identified where although it is optimal for the technological leader to locate in isolation, from a welfare perspective it would be desirable that she locates in the cluster.
Over the 2000s', consumers' food purchases have been increasingly informed by supply chain-related issues, with growing concerns about the sustainability of chains differing for their geographical scope. As a result, short food supply chains and local food systems have risen to policymakers and food chain stakeholders' attention as more sustainable alternatives to mainstream food networks. However, associating food chain's geographical scope and sustainability performance may not be straightforward. This paper aims at shedding lights on the connection between geographical scope and sustainability by comparing and discussing 19 attributes owing to different sustainability dimensions. The analysis anchors on the wheat-to-bread chain, due to its global relevance. Bread is a worldwide staple food and wheat is (generally) a commodity traded globally. However, wheat processing often occurs locally and baking is influenced by local heritage and consumption patterns, particularly in the EU and in Italy, where gastronomy is culturally embedded. The paper identifies critical aspects and provides a qualitative assessment of the performances of local vs global wheat-to-bread chains. The assessment is carried out on Italian case studies.

The negative impacts of the COVID-19 pandemic have further exposed and exacerbated the structural weaknesses and inequalities embedded in the global industrial agri-food system. While the mainstream narrative continues to emphasise the importance of ensuring the uninterrupted functioning of global supply chains to counter COVID-related disruptions, the pandemic has also highlighted the resilience of small-scale, sustainable family farming and of spatially and socially embedded food systems. Based on a quantitative and qualitative analysis of three surveys, this study examines organic and agroecological farmers’ responses to the first COVID-related lockdown (March–May 2020) in Italy, as well as the responses of grassroots alternative food networks (AFN) in the city region of Rome. The results show how local grassroots action played a significant role in ensuring food access, provisioning, and distribution, often in the face of delayed or insufficient action of mainstream food system actors and institutions. These grassroots responses identify opportunities and barriers for agri-food system transformation away from neoliberal, market-based interventions and towards policies that support food sovereignty and democracy in the context of localised, agroecology-based and more resilient agri-food systems.
