This report captures the main findings of the European Commission (EC) Conference entitled "Harnessing Research and Innovation for FOOD 2030: A science policy dialogue", which was held in Brussels on 16th October 2017 on the occasion of World Food Day. The event, which represents an important milestone in the EC's FOOD 2030 process, served to showcase promising Research and Innovation (R&I) outcomes contributing to sustainable food systems transformation in Europe and beyond. Furthermore, the conference provided a space for multi-stakeholder reflection and dialogue towards envisioning future R&I needs relevant to the urgent issue of ensuring long term food and nutrition security, particularly challenging due to the compounded effects of climate change, resource scarcity and increasing global demand for food. The outcomes will further feed into the deliberations of the FOOD 2030 EC Expert Group and the Second FOOD 2030 High Level Event under the Bulgarian Presidency of the Council to be held in Plovdiv in June 2018.
