Sustainability Performance of Local vs Global Food Supply Chains: a Comparative Assessment for Bread in Italy

There is an increasing interest in the potential of local foods and short food supply chains to overcome the unsustainable practices of global/industrial food supply chains. The opposition between local and global food systems is being questioned together with the actual sustainability performance of food chains. The assessment of the sustainability of food chains is challenged by the multiple dimensions to be considered, the diversity of actors involved, and the lack of a shared methodology. This paper presents a preliminary result of the EU research project Glamur (Global and Local Food Assessment: a multidimensional performance based approach) and develops a comparative assessment among three wheat-to-bread chains in Italy in relation to their degree of localness and different dimensions of sustainability. We develop a comparative assessment on two critical attributes of sustainability: nutritional value of bread and biodiversity preservation. The assessment is based on a set of indicators selected within a DPSIR framework. This allows to shed light on synergies and tradeoffs between local and global chains and potential paths for sustainability improvement.
