Themes

Gender

The CGIAR Research Program on Roots, Tubers and Bananas (RTB) has developed a multi-faceted gender strategy that will be woven through its research and development portfolio during  the first three-year phase of the program and beyond. The strategy has been developed over several months and is based on extensive consultations with a wide range of stakeholders. The overall objective […]

Theme 7. Enhancing impact through partnerships

RTB strongly believes in the potential of formal and informal partnerships to mobilize complementary expertise and ensure that impacts are achieved in a cost-effective manner. To fully exploit this potential, the process of partnership building and management needs to be an integral part of program planning, drawing on a range of tools and experiences for […]

Theme 6. Promoting postharvest technologies, value chains, and market opportunities

RTB are consumed as a staple or supplementary food by the rural poor across much of the developing world. They enter in the transition to more market-based food systems, especially through added value products, both fresh and processed. Bulkiness and perishability have traditionally limited RTB use to on-farm and local markets. Specialized storage conditions or […]

Theme 5. Developing tools for more productive, ecologically robust cropping systems

Rural households in developing regions often grow RTB with few inputs beyond their own labor, land, and rainfall. What they produce is mostly used for subsistence consumption. However, market-oriented production opportunities are expanding, and traditional strategies to maintain crop and land productivity are increasingly complemented with purchased fertilizers and, in some cases, irrigation, especially for […]

Theme 4. Making available low-cost, high-quality planting material for farmers

The quality and availability of planting material are a recurrent concern of small farmers in developing countries, particularly for those who grow RTB crops. Organizations dealing with plant health issues are also concerned about planting material, because it is often an important carrier of new or existing pests and diseases. Planting material is a key […]

Theme 3. Managing priority pests and diseases

Pests and diseases can reduce yields and even wipe out RTB crops, both in the field and post-harvest. Pests and diseases of RTB crops include some of the most devastating biotic agents known, including diseases such as the viruses of cassava that threaten food security in parts of Eastern and Central Africa and the potato […]

Theme 2. Accelerating the Development and Selection of Cultivars with Higher, More Stable Yield and Added Value

The goal of Theme 2 is to exploit the genetic resources of RTB to improve productivity, enhance climate change adaptation and resilience, and boost nutritional content and commercial value. RTB crops share challenges regarding their breeding. They are genetically complex and sensitive to inbreeding. Because they are vegetatively propagated, RTBs exhibit relatively low multiplication rates and […]

Theme 1. Unlocking the value and use potential of genetic resources

The four RTB Centers (Bioversity, CIAT, CIP, IITA) play a leading role in the global conservation of RTB genetic resources both in farmer fields and natural habitats in their centers of origin (in-situ) and in genebanks (ex-situ). Each belongs to the “Clonal Crop Task Force” of the Inter‐Center Working Group on Plant Genetic Resources, which […]
