E-book Root, Tuber and Banana Food System Innovations : Value Creation for Inclusive Outcomes
Root, tuber, and banana (RT&B) crops play a critical role in food and nutrition security in developing countries, increasingly so in sub-Saharan Africa (SSA). They have great potential to contribute to alleviate poverty, improve health and nutrition, and enhance the resilience of smallholder farmers to climate change. However, RT&Bs are characterized by unique challenges and, until recently, have suffered from neglect in both investment and research (Fig. 1.1). The CGIAR Research Program on Roots, Tubers and Bananas (RTB hereafter), which operated from 2012 to 2021, represents a novel and successful innovation model within the agricultural research for development domain. This program built upon the uniqueness of RT&B crops, including vegetative propagation, genetic complexity, and postharvest con-straints with bulkiness and perishability, compared to cereals, and also their high yield potential and the ability to deliver micronutrients at large scale.Historically, RT&B crops have suffered from lower investment, and thus, this field of research features fewer researchers than other crops. In this context, RTB raised the profile of this important crop group for global food and nutrition security and served as an effective advocate for more investment. As different chapters in the book will make clear, RTB has not only focused on developing and implementing articular innovations but has also addressed broader constraints for scaling innova-tions, since innovation only creates value when embraced and adopted by its users and beneficiaries at scale.This book delivers an updated stance on innovations in RT&B crops, within and outside of the CGIAR program. We will touch on how to design innovations with a high likelihood of success and impact and provide several successful examples of innovations in RT&B crops while examining the scaling readiness of the innovations.
