Since 2008, JICA has made great efforts toward doubling rice production in Sub-Saharan Africa in 10 years. This study explains JICA's approach and projects and reviews the research findings on JICA's rice training projects. The trainings on rice cultivation practices increased the rice production of the training participants, not only in the short term but also in the long term. The training benefits seem to spill over to the neighbors within the same irrigation scheme. When introducing upland rice to areas where rice was not grown, selecting areas suitable for rice cultivation is a key for sustainable adoption and production.
