Outline of Final Research Achievements

This research constructed panel datasets of rice farmers in eight Sub-Saharan countries. We have found the following three. (1) Recent economic growth and a substantial increase in international rice price have been accelerating domestic rice production as a cash crop, but it does not necessarily induce a rise of productivity like a green revolution because production can be augmented by area expansion too. (2) Technology dissemination to farmers through training effectively enhances productivity, although its scale-up remains a problem. (3) Rice farmers’ income increases in most cases once their technology is improved and the productivity is enhanced. Therefore, we can conclude that the promotion of rice production is an effective way to reduce poverty.
