Abstract

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
灌溉水箱是传统上由当地社区管理的公共水池资源的典型例子。然而,泰米尔纳德邦社区管理下的坦克性能在过去几十年中有所下降,并威胁到当地的生计。本研究利用在泰米尔纳德邦100个水箱密集型村庄收集的两个时期的村级数据,调查了社区管理对灌溉水箱性能的影响。为了解决主观测量中遇到的问题,本研究采用了一种客观评估方法,使用陆地卫星7号的卫星图像来推导坦克性能测量。然后将卫星数据与实地调查数据结合起来,用于分析。结果表明,社区参与水箱管理对水箱性能有显著的积极影响,这表明加强灌溉水箱管理的传统机构可能是振兴水箱灌溉系统的可行策略。
