Achieving food and nutrition security (FNS) is a priority in developing countries. One of the key routes to achieve a resilient global food system and improved FNS requires a reorientation of relevant policies. Among them, policies associated with the creation, adoption and adaptation of technologies, knowledge and innovations and with their related institutional adjustments are key factors to counter the complex and evolving challenges of the global food system. In line with this notion, the objectives of this chapter are severalfold. First, we discuss the main features of innovations for FNS. Second, we describe the impact of innovations on FNS using the examples of new platform and traditional technology. Third, this chapter elaborates on the views of a variety of stakeholders concerning the impacts of technological and institutional innovations, as well as the future priorities of FNS innovation.
