Irrigation tanks are classic examples of common pool resources that have been traditionally managed by local communities. However, the tank performance under community management in Tamil Nadu has declined over the last few decades and threatened the local livelihoods. This study investigates the effect of community management on irrigation tank performance using village-level two-period data collected across 100 tank-intensive villages in Tamil Nadu. To address the problems encountered in the subjective measures, this study adopts an objective assessment method using the satellite imageries of Landsat-7 to derive tank performance measures. Satellite-derived data are then incorporated with the field survey data and used in the analysis. The results show that community participation in tank management has a significant positive impact on tank performance, suggesting that strengthening traditional institutions in irrigation tank management can be a viable strategy for reviving tank irrigation systems.

基于社区的水箱灌溉系统的性能及其决定因素：来自印度泰米尔纳德邦的证据

灌溉池是传统上由当地社区管理的公共池资源的典型例子。然而，泰米尔纳德邦社区管理下的坦克性能在过去几十年里不断下降，威胁到了当地的生计。本研究利用泰米尔纳德邦 100 个水箱密集型村庄收集的村级两期数据，调查了社区管理对灌溉水箱性能的影响。针对主观测量中遇到的问题，本研究采用客观评估方法，利用Landsat-7卫星图像得出储罐性能测量值。然后将卫星数据与现场调查数据合并并用于分析。
