Materialization of West African Green Revolution through Sawah Based Eco-technology and Creation of African Adaptive Satoyama watershed Systems

在过去的50年里，几乎所有的农业研究成果都不能推广到农民的田地里。因此，绿色革命尚未实现。为了实现绿色革命，本文对以下两个假设进行了检验，即：(1)农民田间sawah系统的发展是应用科学技术的前提条件（sawah假设1）；(2)特定地点的低地sawah系统可以维持水稻产量高于4吨/公顷（sawah假设2）。为了证实这两种假设，我们开发了战略认知生态技术集。这项技术使农民能够开发他们的个人灌溉系统，并在三年内使用一台动力播种机（3000- 5000美元）每季生产20-50吨稻田（相当于10,000-25,000美元）。这项技术在加纳的50个地点和100个地点以及尼日利亚的100个地点和200个地点成功地进行了测试。该技术得到了世界银行和两国政府的积极评价，该技术可以在成本方面大幅改革传统的基于ODA的灌溉项目，低于10%，并通过内生发展实现可持续性。目标是在全国和撒哈拉以南非洲地区广泛推广该技术，与jicto合作实现绿色革命梦想。

Almost all agricultural research resultscould not scaleup to farmers 'fieldsduring last 50 yearsin Africa. Thus, the Green Revolution is yet to be realized. In order to realize the green revolution, following two hypotheses were tested, i. e., (1) the development of sawah systems atfarmers' fieldsis the prerequisite condition to applyscientifictechnologies(Sawah hypothesis 1), and (2) site-specific lowland sawahsystems can sustain rice yield higher than 4t/ha(Sawah hypothesis 2). In order toconfirm the two hypotheses, the strategicsawah ecotechnologyset wasdeveloped. The technologymakes possible farmersto develop their personal irrigated sawah systems and to produce20-50 tonsof paddies(equivalent to$ 10,000-25,000) per season using one powertiller($ 3000-5,000) within three years. The technology wassuccessfully testedat 50 sites and 100 hain Ghanaand 100 sites and 200 hain Nigeria. The technologywas positively evaluated by World Bank and the two governments, whichcan reformdramatically traditional ODA based irrigation projectsin terms of cost, less than 10%, and sustainability byendogenous development. Thegoalis nation-wide and Sub Saharan Africa wide scale up of the technology in collaboration with JICAto realize green revolution dream.
