Reflections on “Some Unsettled Problems of Irrigation”
通过分析Katharine Coman在《美国经济评论》首期关于美国西部灌溉集体行动问题的文章，并运用社会生态系统框架组织变量，发现改变正式治理结构不足以确保有效投资和农民生计，而建立知识与信任至关重要。
It is instructive to read the article that Katharine Coman published in the first issue of the American Economic Review to gain insight into the problems of collective action related to irrigation in the American West. One gains further understanding of the problems Coman identifies by using a social-ecological system (Ostrom 2007, 2009) to organize the diverse variables identified by Coman. One gains a general lesson from this analysis that changing the formal governance structure of irrigation is not sufficient to ensure efficient investment in facilities or that farmers are able to acquire property and make a reasonable living. Building knowledge and trust are, however, essential for solving collective-action problems.
