Creation of new methods for African rice assistance to the bases of area study

自2008年以来，日本政府主导的对非洲水稻种植的支持已经持续了10年。在肯尼亚西部维多利亚湖附近的目标区域，有一个地方，在20世纪70年代，肯尼亚政府建立了大型灌溉系统，称为国家灌溉委员会（National irrigation Board， NIB），并引入了灌溉水稻种植。另外，开始调查后发现，至少有6个水稻种植区被称为“种植户”，由农民管理供水。经过两年和不同季节的初步调查，对400户稻农进行了基线调查。结果发现，在NIB下的每单位面积和每户水稻产量都高于水稻农民。另一方面，我们还发现，在我们调查的4个种植户中，水稻的生产力和盈利能力存在很大差异。另一方面，我们还发现，在我们调查的4个种植户中，水稻的生产力和盈利能力存在很大差异。在利润较低的外农中，约40%的稻农在研究年度因种植水稻而蒙受损失。

Support for rice cultivation in Africa has been performed by Japan government-led for 10 years since 2008. In target area located near the lake Victoria in western Kenya, there is a place in which large irrigation systems has been built by Kenyan government called National Irrigation Board(NIB) in the 1970s, and irrigated rice cultivation has been introduced. In addition, after starting survey, it was found that atleast six rice cultivation areas called out grower where farmers manage the water supply by them. After a preliminary surveys during the two years and different seasons, was carried out a baseline survey of 400 households rice farmers has been conducted. As a result, rice production under the NIB was found to be higher compared to the rice farmers out glower in both per unit area and per household. On the other hand, it was found also that there is a large difference in productivity and profitability of rice among four out growers which were investigated. On the other hand, it was found also that there is a large difference in productivity and profitability of rice among four out growers which were investigated. In the less profitable out grower, about 40% rice farmers was loss by rice cultivation in the study year.
