Trans-Disciplinery Study on Irrigation Technique Transfer Projects from Viewpoint of Sustainable Regional Development

20世纪50年代至80年代，以增加粮食产量和农民收入为目标的灌溉发展项目得到了广泛的推广，但在20世纪90年代，这些项目一度陷入低迷，在21世纪，随着水问题成为全球性问题，这些项目成为人们关注的焦点。首先，我们的团队对日本的灌溉项目进行了整体分析，特别是爱知县优穗灌溉项目，该项目的用水热情非常高。我们调查了1960年代写的各种文件，并采访了该项目的发起人。然后，从可持续性的角度分析了日本官方发展援助资助的印度尼西亚西拉威西岛、爪哇岛、巴厘岛和龙目岛的灌溉发展项目。在印尼东部，不仅传统的水资源开发项目，而且以节水和高生产率为目标的新项目也在不断推广。在这些项目中，正在进行新技术的启蒙和推广。在一些项目区，农民收入得到了改善，福利得到了提高。在印度泰米尔纳德邦，位于城市边缘地区的传统罐（库）灌区在土地利用、水资源利用和劳动力分配等方面受到破坏。在这方面，应该追求新的秩序，以导致新的可持续条件。通过这些案例研究，选择土地生产率、水生产率、劳动生产率、与其他行业的竞争力等作为灌溉技术转移项目的评价指标。在项目实施过程中，农民、捐助者和地方政府等主体之间的角色分配被提取出来，成为一个重要因素。

Irrigation Development Projects, aiming food production increase and rural income increase, had been spread in from 1950's to 1980's, however, the projects had depressed in 1990's, then became into the spotlight in the 21st century, after the water problems have become a global issue..First, our team analyzed irrigation projects in Japan holistically, especially in Aichi Yousui irrigation project, in which the eagerness of water users is very high. We investigated various documents written in 1960's and made interviews to the promoters of the project. Then, irrigation development projects in Selawesi, Jawa, Bali and Lombok islands of Indonesia funded by Japanese ODA are analyzed from viewpoint of sustainability. In eastern Indonesia, not only traditional water resource development projects but also new projects which aim water saving and high productivity have been spreading recently. In those projects, enlightenment and distribution of new techniques are in execution. And in some project area, improvement of farmers' income and increase of welfare are reported.In Tamil Nadu state in India, traditional tank (reservoir) irrigation areas located in urban fringe area are damaged in land use, water use and labor distribution. In which area, new orders should be pursued to lead to new sustainable conditions.Through these case studies, land productivity, water productivity, labor productivity, competitiveness with other industries and so on are chosen as evaluation indicators of irrigation technique transfer projects. And in the process of the projects, role allotments between main actors, such as farmers, donors and local governments, are extracted to be an important element.
