The project aims to step change manufacturing productivity, consumer safety, financing and trust within the food supply chain. nnnn Emerging from the case were innovative new applications connected to supply chain performance data, as well as new challenges associated with privacy and commercially sensitive data.    nnnn The challenge is interdisciplinary, affecting the areas of food production, land use, policy/regulation, food logistics, energy systems, consumer behaviour, and many others. nntt n
