Outline of Final Research Achievements

The management of irrigation facilities has tended to shift from government-led management to farmer participatory management. In this study, 34 water users' associations receiving irrigation water supply from the Kulambu- Wilalung trunk canal in Indonesia, where a distinctive change in irrigation governance has been observed, were included in the study. In the study sites, two forms of governance of water users' associations, Swakelola and Lelang, have emerged since 1990. In addition, there has been a steady shift from Swakelola to the new system of Lelang, which uses auctions, with associations adopting a new system of governance. The reasons for the institutional change can be attributed to the existence of economic advantages for farmers, who are oriented towards quick infrastructure investment, and for association chairpersons, who can provide funds and obtain water use fees.

Academic Significance and Societal Importance of the Research Achievements

農家が直面する公共財や共有資源の配分問題の解決にとって農民コミュニティが創出する制度は重要な役割を果たす。本研究では、インドネシアの灌漑システムを事例に、灌漑施設や農道など利用料金を徴収することが不可能なインフラの供給を市場メカニズムのオルタナティブとして農民自らが自発的に制度を創出することによっていかに解決したかを事例分析を通して明らかにした。
