Cassava Annual Report 2019 The Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT) delivers research-based solutions that address the global crises of malnutrition, climate change, biodiversity loss, and environmental degradation. The Alliance focuses on the nexus of agriculture, environment, and nutrition. We work with local, national, and multinational partners across Africa, Asia, and Latin America and the Caribbean, and with the public and private sectors and civil society. With novel partnerships, the Alliance generates evidence and mainstreams innovations to transform food systems and landscapes so that they sustain the planet, drive prosperity, and nourish people in a climate crisis. The Alliance is part of CGIAR, the world’s largest agricultural research and innovation partnership for a food-secure future dedicated to reducing poverty, enhancing food and nutrition security, and improving natural resources. www.alliancebioversityciat.org www.bioversityinternational.org www.ciat.cgiar.org www.cgiar.org CIAT. 2020.

What’s more, cassava and AGROSAVIA) and private organizations (i.e., will be a key crop to make crop production systems INGREDION and TTDI) primarily interested in more resilient to climate change in tropical better cassava varieties, access to clean planting environments. This potential will also increase the materials, monitoring and surveillance of pests crop’s susceptibility to pests and diseases, which and diseases, improved farming and postharvest will have a greater range of mobility. In most parts practices, and the development of sustainable of the tropics, cassava production is now labor- cassava value chains to unlock new cassava market intensive and subsistence-oriented, with low levels growth. of technology uptake, high production costs and postharvest losses, and weak linkages to markets, The following are some of the remarkable results despite being a feedstock for numerous industrial the Cassava Program achieved during 2019, applications, including food, feed, and starch. working under the six Research and Service Areas. The fact that Latin America is the center of origin for cassava was a compelling factor for CIAT to create its Global Cassava Program in the early 1970s, prioritizing cassava research that could not only serve the region but also provide diverse germplasm for the planned Cassava Program at the International Institute of Tropical Agriculture (IITA). After nearly 50 years, the program continues to deliver on its initial objective and has embraced the challenges outlined in the United Nations’ Sustainable Development Goals. The Global Cassava
