The current food system is not able to produce food to nourish the people in a sustainable way. Less environmental impact, resource use efficiency, maintaining soil fertility, closing of nutrient cycles, stable harvests, improved distribution, avoiding food losses/food waste, fair business models and food sovereignty are the main challenges in the current food system. The new design of existing or new supply chains on a local, regional and international level are of special relevance. They should be designed to foster the UN Sustainable Development Goals (SDG), which entered into force on 1 January. Young scientists will be relevant actors in this process of change. For them, ZHAW and FiBL offers an open online course and the opportunity to participate in th international summer school. The whole programm focuses on the topic of "Designing Food Value Chains to foster the UN Sustainable Development Goals."
