RTB Narrative

RTB is planning a second phase beginning in January 2017

The CGIAR Research Program on Roots, Tubers and Bananas (RTB) is one of eight Agri-Food System CRPs (AFS-CRP). During the second phase it will incorporate livelihood systems work, especially from the CRP Integrated Systems for the Humid Tropics (Humidtropics) with which strong collaboration has been established. It will expand collaboration with four Global Integrating CRPs which work on important topics such as Climate Change, Policy, Nutrition and Health and Water and land use. It will also work much more closely with  the AFS-CRPs which work on cereals, legumes, fish, livestock and trees which are part of  the new CGIAR portfolio.

RTB brings together four CGIAR centers (Bioversity, CIAT, CIP, and IITA) and CIRAD (also representing the French organizations IRD, INRA, and Vitropic) with more than 200 partners for research on banana, cassava, potato, sweetpotato, yam, and minor roots and tubers. Termed “vegetatively propagated staple crops,” they are linked by common breeding, seed, and postharvest issues, and by the frequency with which women are involved in their production and use. RTB crops are the backbone of food security in a swathe of countries running through the humid tropics in Sub-Saharan Africa (SSA) and in more localized areas of Asia and Latin America. Elsewhere, RTB crops often complement maize, rice, wheat, legumes, vegetables, and livestock, while also forming part of many agro-forestry systems. Around 300 million poor people in developing countries currently depend on RTB value chains for food and nutrition security and income; many more benefit through their consumption. RTB crops are increasingly taking on roles in income generation in value-added markets. However, climate change could potentially undo progress in poverty reduction and markedly increase food insecurity especially in SSA where RTB crops are the most important.

Agri-food systems affect the incomes of those employed in them, the nutrition and health of consumers, and the quality of the natural resource base. They embody a mosaic of different crops, animals and fish and other options at different levels of scale and involve women and men in varied and changing roles. Hence RTB research requires appropriate involvement of women and men at each of these levels from household, to community to landscape and above and promotes the use of participatory and multi-stakeholder approaches, aimed at strengthening engagement and targeted at livelihoods enhancement.

RTB and its partners, will conduct research for development (R4D) on its key crops and support scaling to achieve the following goals over the  six years of the second phase:

RTB will achieve these goals with five interlinked and interactive flagship projects (FPs).

Flagship Projects


Flagship Project 1 (FP1) contributes breeding methods and tools such as markers and new traits that can be incorporated into the Flagship Project 2 (FP2) clusters as its primary next users. It seeks to influence changes in policy and regulatory frameworks for enhancing conservation and safe exchange of RTB genetic diversity. FP2 includes not only all of the upstream part of the breeding for each of the crops, but also complementary seed and other technology and approaches for demand creation based on systems analyses. Each of the FP2 clusters has its own scaling strategy, but FP2 also links with Flagship Project 3 (FP3) and Flagship Project 4 (FP4) as next users of prototype varieties that require further participatory selection to match end user’s needs and particular constraints (e.g., disease resistance).

FP3 develops an array of products for pest and disease characterization and management in diverse crops and improved agronomy for more resilient cropping systems, but also for supporting breeding efforts. FP4 also uses prototype varieties with high micronutrients or desired postharvest, processing and consumer traits. Likewise, it develops set of research products which complement varieties and translates them into nutrition outcomes, improved efficiency in postharvest technology, and reductions in postharvest loss. Flagship Project 5 (FP5) functions as a systems research platform and as an “innovation broker” and provides a livelihood system-related guiding framework for the whole set of flagships to steer them toward the areas of greatest return, build their capacity for better partnering and capacity development, provide evidence of impact and ensure improved attention and taking into consideration of gender-related aspects.
