peer reviewed ; The Luxembourg government aims to achieve 20% organic agriculture until 2025 and 100% organic agriculture until 2050. The aim of the project is to analyse the impact such a change will have at the farm, as well as on the food system level in Luxembourg. This will be done by conducting a sustainability assessment at the farm-level and the food system-level. For the farm-level sustainability assessment, farm management systems and their respective sustainability implications according to the FAO SAFA Guidelines (Guidelines for the Sustainability Assessment of Food and Agriculture Systems) will be assessed using the SMART-Farm Tool. At the food system-level, the mass-flow model of the agriculture and food sector Soil and Organic Livestock (SOL)-Model will be employed to analyse the environmental implications of dietary patterns and agriculture production systems, where the data from the farm-level assessment will be used to increase specificity of the scenarios.
