This paper summarises selected research activities at Crops For the Future (CFF) in pursuit of its mission ‘to develop solutions for diversifying future agriculture using underutilised crops’. CFF is a research company focussed on the improvement of underutilised crops, so that they might be grown and consumed more widely with benefits to human food and nutritional security; its founding guarantors were the Government of Malaysia and the University of Nottingham. From its base in Malaysia, it engages in research around the world with a focus on species and system diversification. CFF has adopted a food system approach that adds value by delivering prototype food, feed and knowledge products.
