Cassava has become an important crop in South-East Asia, both for the livelihoods and income of smallholder households and for national economies. This small research activity will review the cassava value chains in South-East Asia, focusing on Vietnam and Indonesia. It aims to gain a better understanding of the production, marketing, and processing systems and how they vary within these countries and across the region. It also aims to identify likely research, development, extension, and policy requirements for the future. Outputs will include a report on cassava value chains in the region, and an assessment of major activities needed to drive improvements in the sector.
