DEVELOPMENT STRATEGY FOR HILLSIDE AGRICLTURE WITH THE BASIN NETWORK FRAMEWORK

在本研究中，引入了“流域系统”、“网络”和“山坡”等农业农村发展与改善战略的关键概念。在这里，“流域系统”被定义为一个经济圈，在这里，水的需求和供应系统被有机地组织成一个独立的水网。运用“流域系统网络”的概念，以日本关西地区为例，提出了丘陵地区发展山地农业的策略。因此，首先提出并讨论了基础设施改善项目的内容，并将其应用于基诺河流域的案例中。其次，池塘灌区灌溉管理系统的原理，主要针对历史上由农民制定的习惯管理规则下的小池塘灌溉管理制度。对阪神-Awaji大地震对灌溉系统的影响进行了评估，结果表明，在异常情况下，网络形式的系统是灵活的和有弹性的。最后，对涉及风险管理的农村发展战略进行了讨论，并建议在日本未来的项目中使用。然后，从环境保护的角度讨论了灌溉系统存在的问题，并介绍了琵琶湖流域的情况。

In this research, introducing key concepts of "Basin system", "Network" and "Hillside", the strategy for development and improvement of agriculture and rural area. Here, a "basin system" is defined as an economic sphere where the water demand and supply system is organically organized as one dependent water network. Using the concept of "basin system network", the strategy for promotion of hillside agriculture in hilly areas is proposed, base on case studies mainly in the Kansai Region, Japan. As the result, firstly, contents of infrastructure improvement project was proposed and discussed to be applied to the case in the Kino-River Basin. Then, measures for conservation of terrace paddy fields with less labor productivity are discussed, in comparison with consolidated lowland paddy fields where lager farming system could be established with larger agricultural machines.Secondly, the principle of irrigation management system in pond-fed irrigation areas, focusing on the small ponds in the Awaji Island with customary management rule historically developed by farmers. Evaluation of the effect of the Hanshin-Awaji Great Earthquake on the irrigation system make clear that the network style system is flexible and elastic in the case of unusual situation.Finally, the rural development strategy involving the risk management was discussed and proposed to be utilized in the future projects in Japan. Then, problems on irrigation system in view of the environmental conservation were discussed, introducing the case of the Lake Biwa Basin.
