The CGIAR Research Program on Roots, Tubers and Bananas (RTB) is one of a new series of initiatives spearheaded by CGIAR to bring together the research synergies and resources of multiple agricultural research-for-development centers to improve efficiencies and increase impacts. The purpose of RTB is to tap the underutilized potential of root, tuber, and banana crops to improve food security, nutrition, and livelihoods.
