CORE Organic is an ERA-NET - a network of European ministries and research councils funding research in organic food and farming systems funded in 2004. The main focus of the ERA-NET is to join forces and fund transnational research projects supporting a focused and coordinated research and innovation effort covering the most important challenges along the organic value chains. The network receives funding from the European Commission under the "Horizon2020". During 15 years of joint collaboration, ERA-NET CORE Organic partners launched seven transnational calls under CORE Organic I, CORE Organic II, CORE Organic Plus and CORE Organic Cofund for around 48 million EUR of funding.
