Although Central-South America is the original place of cassava, currently the most cassava producing region is Africa, and Asia is leading its industrial utilization. And research efforts have been ignored to cassava in C-S America. However, most recently there have been changing situation of concerns of production and utilization about cassava in Brazil.

Moreover, the North and the Northeast regions are put in the domestic, specialization of cassava production and distribution which is led by the Southern region. There are strong needs for the investment on research and development (R&D) for cassava, not only in production technologies but also in processing and marketing systems, and on coordination between companies and farmers relate to cassava.

This is the good opportunity to learn from Brazilian experience, in terms of cassava production technologies, marketing and distribution systems, in the middle of its another prosperity of the cassava sector.
