Recent increases in rice consumption in Sub-Saharan Africa are noteworthy. Most of the rice production in these countries depends on an enormous number of small-scale rice farmers. Because they have a poor investment capacity to follow the green revolution, that is, high-yield variety with fertilizer and irrigation, it is necessary to raise the annual production by increasing the number of annual cropping and to improve the water productivity drastically. Salibu rice ratooning technology allows harvesting paddy rice seven times in two years by cultivating ratoon crops with high yield and dramatically low consumption of irrigation water. The authors have conducted a series of cultivation tests in Ghana for over a year and found that the average annual production of rice under the Salibu system was higher than that of the conventional rice cultivation system with much higher water productivity. The authors have also conducted a social experiment on commercial finance by rural banks to farmer-based organizations (FBOs), organized by small-scale rice farmers. The first target of the scheme is group purchasing of small agricultural machinery, which most of the members of the group eagerly want to obtain. We introduced special collateral systems in order to persuade rural banks reluctant to make finance to rice farmers. After realizing the first commercial finance by rural bank to FBO the path to realizing future investment in irrigation was set out in a scenario of gradual solidarity and development.

改变不愿投资发展的小农的紧张心态*

近期撒哈拉以南非洲大米消费量的增长值得注意。这些国家的大部分稻米生产依赖于数量庞大的小规模稻农。由于他们跟上绿色革命的投资能力差，即施肥灌溉的高产品种，需要通过增加一年生作物的数量来提高年产量，大幅度提高水生产力。萨里布水稻再生技术通过培育高产且灌溉水消耗极低的再生作物，可以在两年内收获七次水稻。作者在加纳进行了一年多来的一系列栽培试验，发现萨里布系统下水稻的年均产量高于传统水稻种植系统，水生产力高得多。作者还进行了农村银行向小稻农组织的农民组织（FBO）商业金融的社会实验。该计划的第一个目标是小型农业机械的团购，这是大多数团员都渴望获得的。我们引入了特殊的抵押制度，以说服农村银行不愿意向稻农提供融资。
