"Increasing diversity within agricultural systems by intercropping offers a realistic and practical opportunity to enhance and stabilise crop yields and produce food, feed and fuel with fewer inputs. As environmental conditions become more variable, diversifying cropping systems can also reduce production risks. The Horizon 2020-funded projects DIVERSify and ReMIX, alongside other projects, are conducting research trials as well as working with farmers and other agricultural stakeholders across Europe and internationally to design, test and provide practical solutions for multi-species intercropping. It is timely to bring together the intercropping community to showcase the latest findings on intercropping research from the lab and the field and encourage debate on uptake and best practice. DIVERSify and ReMIX are working with other Horizon 2020-funded projects in the Crop Diversification Cluster to transfer project findings to scientists, farmers, advisers, industry and policy makers (see www.cropdiversification.eu for information about other joint events). The Congress will cover topics that range from basic research to practical application of intercrops."
