ABSTRACT

This study examines the importance of generating proper water accounts for large gravity-based irrigation schemes in order to assess scheme performance. It shows how the use of simplistic criteria used to assess the performance of gravity-based irrigation schemes can lead to an underestimation of the role they play in enhancing food security and agricultural production in countries such as India, which has established a huge network of irrigation canals. The paper offers specific suggestions on improving irrigation statistics that, in turn, can help in better evaluation of the returns on investments of public surface irrigation schemes.

摘要

本研究探讨了为基于重力的大型灌溉计划生成适当水帐户的重要性，以评估计划绩效。它显示了使用简单的标准来评估基于重力的灌溉计划的绩效如何导致低估它们在加强印度等国家的粮食安全和农业生产方面所发挥的作用，印度已经建立了一个庞大的灌溉网络运河。该文件就改进灌溉统计数据提出了具体建议，进而有助于更好地评估公共地表灌溉计划的投资回报。
