The Nature of the Governance of Japanese Irrigation Common-Pool Resources

摘要

This study critically analyzes how Japanese irrigators govern their irrigation common-pool resources (CPRs) to address CPR problems. The study contradicts the traditional belief that state and market approaches are necessary to address CPR problems and reveals that a "patronized self-governance" approach can be an effective way to resolve the problems. State and market approaches ignore CPR users' endogenous institutions and recommend that external authorities such as governments exercise coercion tomake rational, self-interested users achieve group benefits or privatize their resources. This study explains why and how a patronised self-governance approach has been effective in managing Japanese irrigation CPRs. While irrigators organize themselvesand formulate endogenous institutions to self-govern irrigation CPRs, the government strategically patronizes the users' self-governance. The irrigators are farsightedly rational in collective action situations and the government does not need to applycoercion to make the rational, self-interested irrigators achieve their common interests.
